본 고안은 분사를 위한 분무기와 고압펌프와의 사이에 연결하여 사용하는 바이패스(By pass)밸브에 관한 것으로서 펌프를 가동시킨 상태에서 잠시 분사 작업을 정지하였을 때 펌프내에 고압과 부하가 걸리지 않도록 하여 동력장치의 마모를 감소시킴으로써 소모동력의 절감과 펌프의 수명을 연장 시킬 수 있도록 한 고압펌프의 압력조절용 우회밸브에 관한 것이다.The present invention relates to a bypass valve that is used between the atomizer for spraying and the high pressure pump, so that high pressure and load are not applied to the pump when the spraying operation is stopped for a while while the pump is running. The present invention relates to a bypass valve for pressure control of a high pressure pump, which can reduce power consumption and extend the life of the pump.
종래에 알려진 통상의 분무용 펌프는 가동중에 분무밸브를 닫았을 때에는 펌프내에 과부하가 걸리게되며 이 과부하 량은 안전밸브를 통해 압력이 배출되도록 되어 있는 것으로 이러한 장치를 이용하여 연료를 보급할때는 연료의 유실을 동반하게 되는 등 실용적이지 못하였으며, 또한 안전밸브를 통해 과부하압이 배출된다고해도 배출되는 량은 이미 정하여져 있는 정격압보다 높은 약간의 압만이 배출될 뿐이고, 펌프의 동력장치에는 여전히 일정한 정격 고압이 부하상태로 작용하고 있게된다.Conventionally known spray pumps are overloaded in the pump when the spray valve is closed during operation, and the amount of overload is to release pressure through the safety valve. It was not practical such as accompaniment, and even if the overload pressure is released through the safety valve, only a slight pressure higher than the predetermined rated pressure is discharged, and the pump power unit still has a constant rated high pressure. It is working in a state.
그러므로 펌프동력장치는 동력의 소모가 많아지게 될 뿐만 마모가 심해 그 수명을 단축시키게되는 문제점을 안고 있는 것이다.Therefore, the pump power unit has a problem that the consumption of power is increased and wear is severe and shorten its life.
본 고안은 이와같은 종래의 문제점을 해결하기위해 펌프와 분무기 사이에 압력우회밸브를 설치하여 펌프가동중에 분사 정지시로 인해 발생되는 과부하압력이 유도배출되면서 펌프내로 재차순환 될 수 있도록 안출한 것으로 그 구성 및 작용효과를 첨부도면에 의해 상세히 설명하면 다음과 같다.In order to solve such a conventional problem, a pressure bypass valve is installed between the pump and the sprayer, and the overload pressure caused by the injection stop during pump operation is discharged so that it can be recycled into the pump. Referring to the configuration and the effect in detail by the accompanying drawings as follows.
펌프(17)와 분무기(14)사이에 연결하는 우회밸브 본체(1)의 밸브실(2) 상측에는 분무기연결용 압력공급구(3)를 천공하고, 좌측에는 캡(4)내부의 스프링(5)에 탄지된 조절밸브(6)를 내장하며 밸브실 우측에는 펌프와 연결되는 유입구(8)를 가진 마개(7)를 끼워 압력 공급선로를 구성하며 마개(7) 일측에는 유입구(8)와 연통되는 체크밸브(9)를 설치하여 펌프로 연결되는 우회배출로(10)를 형성함을 특징으로한 것이다.On the upper side of the valve chamber 2 of the bypass valve body 1 connected between the pump 17 and the sprayer 14, a pressure supply port 3 for connecting the sprayer is drilled, and on the left side a spring inside the cap 4 5) Built-in control valve (6) is mounted on the right side of the valve chamber is fitted with a stopper (7) having an inlet port (8) connected to the pump to form a pressure supply line, one end of the stopper (7) and the inlet port (8) and It is characterized in that by installing a check valve (9) communicated to form a bypass discharge path (10) connected to the pump.
도면중 미설명부호 12는 스프링장력 조절보울트, 15는 분무기 개폐밸브이다.In the drawings, reference numeral 12 denotes a spring tension adjusting bolt, and 15 denotes an atomizer on / off valve.
이와같이된 본 고안은 통상의 방법에 따라 마개(7)의 유입구(8) 우측에 펌프(17)로부터 연결되는 호오스를 끼우고 밸브실(2) 상측의 압력공급구(3)에는 분무기(1) 호오스를 연결하며, 우회배출로(10)에는 다시 펌프(17)로 압이 되돌아 갈수 있도록 우회 호오스를 연결한후 펌프(17)를 가동하여 사용하면 된다.In this way, the present invention inserts a hose connected from the pump 17 to the right side of the inlet 8 of the stopper 7 according to a conventional method, and the sprayer 1 to the pressure supply port 3 above the valve chamber 2. The hose is connected, and the bypass discharge path 10 may be used by operating the pump 17 after connecting the bypass hose so that the pressure can be returned to the pump 17 again.
이렇게 펌프(17)의 가동으로 공급되는 압은 제1도에서와 같이 펌프(17)로부터 마개(7)의 유입구(8)로 들어오게되고 분무기개폐밸브(15)를 열어놓은 상태 이므로 분무기측과 우회 밸브 본체내의 압력차로 인하여 압력은 체크밸브(9)가 있는 우회배출로(10)로 나가지 않고 스프링(5)에 탄지된 조절밸브(6)을 밀고나가 밸브실(2) 상측의 압력공급구(3)를 통해서 분무기(14)로 분사된다.In this way, the pressure supplied by the operation of the pump 17 enters the inlet 8 of the cap 7 from the pump 17 as shown in FIG. 1 and the atomizer opening and closing valve 15 is opened. Due to the pressure difference in the bypass valve body, the pressure does not go to the bypass discharge path 10 with the check valve 9, but pushes the control valve 6 supported by the spring 5 and then the pressure supply port above the valve chamber 2. It is injected into the nebulizer 14 through (3).
이와같이 분사작업을 하고 있다가 잠시 중단할 때 즉, 펌프(17)의 계속적인 가동으로 압이 공급되면서 분무기(14)의 개폐밸브(15)를 잠시 잠글때에는 압이 압력공급구(3)쪽으로 나가지못하기 때문에 이때는 밸브실(2) 및 유입통로에 차여 있다가 유입구(8) 일측에 있는 체크 밸브(9)를 밀고 우회배출로(10)로 나가게 된다.In this way, when the spraying operation is interrupted for a while, that is, when pressure is supplied by the continuous operation of the pump 17, the pressure is released toward the pressure supply port 3 when the on / off valve 15 of the sprayer 14 is temporarily closed. Since it is not possible at this time, the valve chamber (2) and the inlet passage is pushed to the check valve (9) on one side of the inlet (8) and exits to the bypass discharge path (10).
이는 제2도에서 보는 바와 같으며, 압력이 우회배출됨에 의해서 조절밸브(6)은 압의 작용이 없으므로 스프링(5)에 의해 전진하여 밸브실(2)을 차단한다.This is as shown in FIG. 2, and since the control valve 6 has no action of pressure due to the bypass of the pressure, it is advanced by the spring 5 to block the valve chamber 2.
이때 우회배출로(10)로 나간 압은 다시 펌프(17)로 되돌아 가게되므로 압은 계속 순환될 수 있어 펌프(17)에 과부하 압력이 걸리지 않게 되는 것이다.At this time, since the pressure exited to the bypass discharge path 10 is returned to the pump 17 again, the pressure can be continuously circulated so that the overload pressure is not applied to the pump 17.
이와같은 본 고안은 밸브실(2) 상측의 압력공급구(3)로 나가는 압보다 펌핑하는 압력이 더 클 때, 또는 분무기밸브(15)를 잠궜을때에 그 잉여압이 모두 체크밸브(9)를 열고 우회 배출로(10)를 통해 다시 펌프(17)로 돌아갈 수 있도록 하므로서 펌프의 동력장치는 종래와 같이 압에 의해 과부하가 걸리지 않게되는 것이다.The present invention is such that when the pumping pressure is greater than the pressure going out to the pressure supply port (3) above the valve chamber 2, or when the atomizer valve 15 is closed all of the excess pressure check valve (9) By opening the back and back to the pump 17 through the bypass discharge path 10, the power unit of the pump is not overloaded by the pressure as in the prior art.
따라서, 본 고안은 종래와 같이 개폐밸브의 폐쇄에 따라 밸브실의 압력이 상승될때까지 펌프에 무리를 안겨주며 안전 밸브로의 배출로 일시적 압력강하를 시켜 주었던 장치와는 달리 체크밸브를 밀고 우회배출로를 경유하는 압력이 펌프로 흡입되는 과정이 계속적으로 이루어지게 됨에 따라 압력이 밸브실에 과도하게 작용되지 않으므로 펌프에 무리를 주지 않고 하나의 사이클을 이루며 순환되므로 압력으로 작용하는 연료, 또는 물의 유실을 방지하게 되는 것이며, 이러한 순조로운 압력의 흐름은 펌프내의 동력전달 장치의 마모를 감소시킬 수 있는 것이며, 부품의 마모 방지는 동력전달장치의 원할한 구동을 기대할 수 있게되어 수명과 기능을 효과적으로 유지하게 되므로 펌프 구동에 따르는 소모 동력을 절감 할 수도 있게되는 매우 유용한 고안인 것이다.Therefore, the present invention pushes the check valve and bypasses the check valve, unlike the device that puts a pressure on the pump until the pressure in the valve chamber increases according to the closing of the on-off valve as in the prior art, and causes a temporary pressure drop by the discharge to the safety valve. As the pressure passing through the furnace continues to be sucked into the pump, the pressure is not excessively applied to the valve chamber. Therefore, the pressure or the loss of fuel or water acts as it circulates in one cycle without straining the pump. This smooth flow of pressure can reduce the wear of the power train in the pump, and the wear protection of parts can be expected to drive the power train smoothly, effectively maintaining its life and function. Very useful design that can reduce the power consumption of the pump Will.
