Description

휴대용 부탄가스 용기용 과압안전밸브의 휘슬타입 스프링스토퍼{A whistle type spring stoper for safety valve in a gas cylinder}A whistle type spring stoper for safety valve in a gas cylinder

본 발명은 휴대용 부탄가스 용기용 과압안전밸브의 휘슬타입 스프링스토퍼에 관한 것으로 더욱 상세하게는 가스 용기 내부에 과압이 발생할 경우 폭발방지를 위해 과압가스를 배출할 수 있도록 한 과압안전밸브에 있어서; 상기 과압안전밸브의 압축스프링을 고정하는 스프링스토퍼에 과압가스 방출시 피리소리(whistle)가 발생하도록 한 과압안전밸브의 스프링스토퍼 개선안에 관한 것이다.The present invention relates to a whistle-type spring stopper of a overpressure safety valve for a portable butane gas container, and more particularly, to an overpressure safety valve for discharging overpressure gas to prevent explosion when an overpressure occurs in a gas container; The present invention relates to a spring stopper improvement of an overpressure safety valve in which a whistle is generated when the overpressure gas is discharged to a spring stopper fixing the compression spring of the overpressure safety valve.

일반적으로 가스용기는 부탄가스나 각종 분사형 유체 등과 같은 다양한 유체를 충진하여 사용자의 요구에 따라 충진된 유체를 외부로 분사하여 사용할 수 있도록 한 용기의 일종이다.In general, a gas container is a kind of container that fills various fluids such as butane gas and various injection type fluids so as to inject the filled fluid to the outside according to a user's request.

이러한 가스용기에 충진되는 내용물은 부탄가스를 비롯하여 각종 분사형 유체의 경우 원활한 분사를 위해 내용물에 압력을 가할 수 있도록 액화가스(LPG)가 동시에 충진되는데, 부탄가스를 비롯하여 내용물과 같이 충진되는 액화가스의 경우 휘발성이 매우 강한 성질을 가지는 것으로 충격이나 고온이 작용할 경우 용기의 내압을 상승시켜 용기의 변형이나 파열 및 폭발과 같은 안전사고를 유발시킬 수 있는 문제점을 안고 있었다.The contents filled in the gas container are filled with liquefied gas (LPG) at the same time to apply pressure to the contents for smooth injection in the case of various injection type fluids including butane gas, but the contents of the liquefied gas filled with the contents such as butane gas In the case of having a very volatile property, when the impact or high temperature acts, the internal pressure of the container is increased to cause a safety accident such as deformation, rupture and explosion of the container.

그리하여 이러한 가스용기에는 부탄가스나 액화가스의 과압발생시 용기를 보호하기 위해 별도의 과압안전장치인 과압안전밸브가 개재되며, 이러한 과압안전밸브는 다양한 구조와 장착부위에 적용됨이 일반적이다.Thus, such a gas container is provided with an overpressure safety valve that is a separate overpressure safety device to protect the container in the event of overpressure of butane gas or liquefied gas, and such overpressure safety valves are generally applied to various structures and mounting parts.

그 가운데 과압안전밸브의 구성간소화와 장착효율성을 향상시키기 위해 도 2에서와 같이 스템밸브하우징과 안전밸브하우징을 일체화하여 구성한다.Among them, the stem valve housing and the safety valve housing are integrally formed as shown in FIG. 2 in order to simplify the configuration of the overpressure safety valve and improve the mounting efficiency.

상기와 같이 스템밸브하우징(10)과 안전밸브하우징(11)을 각각 독립작동할 수 있도록 구성하면서 각 밸브하우징(10,11)은 일체로 사출성형하여 한정된 공간과 박판의 마운팅캡(100)에서 내용물의 충진과 배출 및 과압작용시 안전밸브 작동을 동시에 수행하여 그 활용도가 점차 증가하고 있는 실정이다.As described above, the valve valve housing 10 and the safety valve housing 11 are configured to be operated independently, while each valve housing 10 and 11 is integrally injection molded to form a limited space and a thin plate mounting cap 100. In the filling and discharging of the contents and overpressure, the safety valve is operated at the same time, and the utilization thereof is gradually increasing.

특히 과압안전밸브(11)는 가스용기 내 과압발생시 스프링의 장력에 의해 폐쇄된 배출로가 개방되면서 과압이 가스용기 외부로 방출되도록 한 안전장치로서,In particular, the overpressure safety valve 11 is a safety device that allows the overpressure to be discharged to the outside of the gas container while the discharge passage closed by the tension of the spring when the overpressure occurs in the gas container,

원주형의 안전밸브하우징(12) 내방으로 평상시 가스의 유출을 방지하기 위한 기밀가스켓(13)이 배출로(14) 상방에 개재되고, 이러한 기밀가스켓(13)은 과압에 비하여 다소 작은 장력을 가지는 압축스프링(15)에 의해 압축된다.An airtight gasket 13 is interposed above the discharge path 14 to prevent the outflow of gas in the columnar safety valve housing 12, and the airtight gasket 13 has a somewhat smaller tension than an overpressure. It is compressed by the compression spring 15.

상기 압축스프링(15)은 스프링스토퍼(16)에 의해 상측이 단속되어 스프링스토퍼(16)와 기밀가스켓(13) 상간에 위치하게된다.The compression spring 15 is interposed by the spring stopper 16 to be positioned between the spring stopper 16 and the upper airtight gasket 13.

이와 같이 압축스프링(15)의 상측을 단속하는 스프링스토퍼(16)는 압축스프링(15)의 단속이외에도 배출로(14)를 통해 방출되는 과압가스의 방출통로(17)를 포함하고 있으며, 이러한 스프링스토퍼(16)는 도 1에서와 같이 합성수재재를 통한 사 출성형되는 것으로, 원통형으로 내방 중심에는 과압가스의 원활한 방출을 위해 상광하협의 방출통로(17)를 형성한다.As such, the spring stopper 16 which intercepts the upper side of the compression spring 15 includes a discharge passage 17 of the overpressure gas discharged through the discharge passage 14 in addition to the interruption of the compression spring 15. The stopper 16 is injection molded through the synthetic resin material as shown in FIG. 1, and forms a discharge passage 17 of a light receiving strait in the inner center to smoothly discharge the overpressure gas.

이상과 같이 구성된 과압안전밸브(11)는 가스용기 사용시 내부에 과압이 발생하면 배출로(14)를 폐쇄하고 있는 기밀가스켓(13)을 상방으로 밀게 되고, 이로 인해 개방된 배출로(14)를 통해 과압가스가 방출되고, 방출된 과압가스는 다시 스프링스토퍼(16)의 방출통로(17)를 따라 가스용기 외방으로 방출되어 과압에 의한 가스용기의 변형이나 폭발을 미연에 방지한다.The overpressure safety valve 11 configured as described above pushes the airtight gasket 13 closing the discharge passage 14 upward when overpressure occurs inside the gas container, thereby opening the discharge passage 14 opened. The overpressure gas is discharged through the discharge gas, and the released overpressure gas is discharged to the outside of the gas container along the discharge passage 17 of the spring stopper 16 to prevent deformation or explosion of the gas container due to the overpressure.

하지만, 과압이 발생하여 과압안전밸브를 통해 외부로 방출되는 과압가스는 누구나 쉽게 간단히 식별하기 어려우며, 이는 현재 사용중인 가스용기가 과압상태인지를 확인할 수 있는 장치나 방법이 전무한 상황이다.However, it is difficult for anyone to easily identify the overpressure gas that is released to the outside through the overpressure safety valve due to overpressure, and there is no device or method for confirming whether the gas container currently being used is in an overpressure state.

이는 과압발생원인을 파악하기 어려우며, 나아가 과압이 발생된 상태에서 계속 가스용기를 사용함으로 인해 연속한 과압현상발생을 야기하여 사용자의 안전사고 유발이 우려되는 문제점이 있었다.This is difficult to determine the cause of the overpressure, and furthermore, the continuous use of the gas container in the state in which the overpressure is generated, causing a continuous overpressure phenomenon, there was a problem that the user's safety accidents caused concern.

또한 별도의 과압표시장치를 추가할 경우 전반적인 가스용기의 생산단가 상승을 초래하고, 이로 인한 사용자의 경제적 부담을 야기하는 원인으로 작용하였다.In addition, the addition of a separate overpressure display device caused an increase in the production cost of the overall gas container, which caused a user's economic burden.

본 발명에서는 종래 가스용기에 과압상태를 표시할 수 있는 장치나 방법이 전무함으로 인해 야기되는 사용자의 안전사고 유발 우려를 해결하기 위함이다.In the present invention is to solve the user's safety accidents caused by the absence of any device or method that can display the overpressure state in the conventional gas container.

본 발명인 휴대용 부탄가스 용기용 과압안전밸브의 휘슬타입 스프링스토퍼는 중공의 원통형 구조로서 하측 선단에는 압축스프링을 안치하는 단턱을 형성하고, 과압가스 방출이 가능하도록 중공으로 형성하여 구성함에 있어서;The whistle type spring stopper of the overpressure safety valve for a portable butane gas container according to the present invention has a hollow cylindrical structure, which forms a stepped portion at which a compression spring is set at a lower end thereof, and is formed by forming a hollow to enable overpressure gas discharge;

상기 스프링스토퍼는 중공 개구(22) 내방의 단턱(20) 경계지점으로 횡격벽(23)을 형성하고, 상기 횡격벽(23)과 일정 거리 이격된 지점에는 스프링스토퍼(2)와 일체로 형성되는 박판의 떨림판(21)이 종방향으로 배치되도록 설치하여 구성한 것을 특징으로 한다.The spring stopper forms a transverse bulkhead 23 at a boundary point of the step 20 in the hollow opening 22, and is integrally formed with the spring stopper 2 at a point spaced apart from the transverse bulkhead 23 by a predetermined distance. The vibration plate 21 of the thin plate is characterized in that it is installed and configured to be arranged in the longitudinal direction.

상기와 같은 본 발명인 휴대용 부탄가스 용기용 과압안전밸브의 휘슬타입 스프링스토퍼는 도 4에 도시된 바와 같이, 휘슬타입 스프링스토퍼(2)가 과압안전밸브하우징(40)의 내측 상방에 위치하고, 이어 스프링스토퍼(2)의 단턱(20)에 압축스프링(30)이 끼움·설치되며, 상기 압축스프링(30) 하단에는 과압가스 배출로(31)의 개폐를 단속하는 기밀가스켓(32)이 압축스프링(30)의 장력에 의해 안전밸브하우징(40) 바닥면에 밀착 개재되도록 하여 사용된다.Whistle-type spring stopper of the overpressure safety valve for portable butane gas container according to the present invention as shown in Figure 4, the whistle-type spring stopper 2 is located above the inside of the overpressure safety valve housing 40, the ear spring The compression spring 30 is fitted and installed in the step 20 of the stopper 2, and an airtight gasket 32 for controlling the opening and closing of the overpressure gas discharge passage 31 is provided at the lower end of the compression spring 30. It is used to be in close contact with the bottom surface of the safety valve housing 40 by the tension of 30).

상기와 같은 상황에서 가스용기 내에 이상 과압이 발생하면, 과압가스는 배출로(31)를 통해 기밀가스켓(32)을 가압하게 되고, 이렇게 발생한 가압력이 압축스프링(30)의 인장력보다 클 경우 압축스프링(30)을 압축하여 기밀가스켓(32)으로 하여금 배출로(31)가 개방되도록 한다.When abnormal overpressure occurs in the gas container in the above situation, the overpressure gas pressurizes the gas-tight gasket 32 through the discharge passage 31, and the compression spring is larger than the pressing force of the compression spring 30. Compress 30 so that the airtight gasket 32 opens the discharge passage 31.

상기 배출로(31)가 개방됨과 동시에 과압가스가 과압안전밸브하우징 내방을 거쳐 휘슬타입 스프링스토퍼(2)의 내측으로 유입되며, 스프링스토퍼(2)로 유입된 과압가스는 횡격벽(23)에 의해 그 방출면적이 감소하여 유속이 증가하게 되고, 유속이 증가로 인해 떨림판(21)에 진동(떨림)현상이 발생하여 진동현상에 따른 피리소리가 발생하게 된다.At the same time as the discharge passage 31 is opened, the overpressure gas is introduced into the whistle-type spring stopper 2 through the inside of the overpressure safety valve housing, and the overpressure gas introduced into the spring stopper 2 flows into the horizontal partition wall 23. As a result, the discharge area is reduced to increase the flow rate, and the vibration is generated in the shake plate 21 due to the increase in the flow rate, thereby generating a flute sound according to the vibration phenomenon.

It is discharged through the wedge-shaped space 26 formed at both edges.

이상과 같은 과정으로 과압가스 방출과 함께 스프링스토퍼에 형성된 떨림판의 진동에 의한 피리소리가 발생하므로, 사용자는 현재 가스용기의 상태를 직감할 수 있게 되고, 이는 곧 사용자가 가스용기의 사용중단을 자연스럽게 유도하여 알지 못하는 상황에서 발생할 수 있는 안전사고를 미연에 방지할 수 있는 결정적 장점을 가진다.Since the flute sound is generated by the vibration of the vibration plate formed on the spring stopper along with the discharge of the overpressure gas, the user can feel the current state of the gas container, which means that the user can stop the use of the gas container. It naturally has the decisive advantage of preventing accidents that can occur in unknown situations.
