Abstract

The utility model relates to a corrugated diaphragm valve with high sealing, comprising a valve body, a seal head and a handlebar. The seal head which is provided in the valve body can plug the through hole in the valve body. The valve is characterized in that the seal head is connected with the handlebar via thread. A corrugated diaphragm is provided between the seal head and the inner wall of the valve to make the handlebar keep away from the sealing of the seal head. The utility model is simple in structure and easy to use, in particular adopts the sandwich rubber corrugated diaphragm made by new technology as isolated seal to make the screw isolated and sealed completely and guarantee the gas from leakage. The valve is suitable for the gas pipeline and the gas holder to use.

Description

High leak tightness convolution diaphragm valve
The utility model relates to the meter valve, specifically a kind of high leak tightness convolution diaphragm valve that is suitable for gas pipe line and gas-tank use.
The house coal gas tank is still used by huge numbers of families at present, and used gas valve is to be enclosed within by seal ring to seal on the valve rod, when the valve open and close, screw mandrel just moves up and down, time has been grown and can cause wearing and tearing, causes producing the gap between valve and the seal ring, is easy to generate gas leakage.The fire that causes because of gas leakage in actual life, blast and security incident are countless, have caused tremendous loss to the people's lives and property.
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, to propose a kind of leak free high leak tightness convolution diaphragm valve, making it have good Security.
For achieving the above object, the utility model adopts following technological scheme: a kind of high leak tightness convolution diaphragm valve, it comprises valve body, end socket and handle, end socket is positioned at valve body and the through hole of valve body can be blocked, its special way be described end socket with handle between link to each other by screw thread, between described end socket and the valve interior wall convolution diaphragm is housed, handle and end socket is sealed keep apart.
Furtherly, link to each other by the mode of sliding sleeve with screw thread between described sliding sleeve and the end socket, the central authorities of convolution diaphragm are clamped by the junction between sliding sleeve and the end socket, and the gland nut that the edge of convolution diaphragm is positioned at the valve body upper end is pressed on the inner face of valve body.
Furtherly, adopt the mode of screw rod and screw to be movably connected between described handle and the slide block, handle is installed in the gland nut of valve body upper end.
Again furtherly, limit position part is arranged above the convolution diaphragm in valve body, this limit position part is a stop collar that is enclosed within the slide block outside, and it is fixed on the junction between gland nut and the valve body.
Specifically, described convolution diaphragm adopts the elastomer diaphragm of interlayer to make, and its interlayer can adopt bright and beautiful silk, nylon wire, silk bolting silk, terylene, metallic sieve.
The utility model is simple in structure, easy to use, and the laminated rubber convolution diaphragm of making of especially adopting new technology makes the complete isolating seal of screw rod as isolation seal, and assurance gas is not revealed.When the handle rotating screw bolt, when promptly opening or closing, gas all can only be in valve body and this airtight area of space of convolution diaphragm, leak free key point that Here it is.This diaphragm can not only be realized high leak tightness, but also flexible displacement amount by moving up and down of screw rod, can be finished the open and close action of valve.Convolution diaphragm is former to be the elastic element of using as instrument, and is used for can initiating at last on the valve.This valve is owing to have a good sealing property, so it can not only be used for gas valve, but also can be used for fields such as all steel cylinder valves and chemical industry, electric power, and every place of high-air-tightness that needs all can be used.
Describe the utility model in detail below in conjunction with the accompanying drawing illustrated embodiment, but protection domain of the present utility model is not so limited.
Accompanying drawing is a structural representation of the present utility model.
The utility model comprises valve body 5, end socket 7 and handle 1, and end socket 7 is positioned at valve body 5 and the through hole of valve body 5 can be blocked.In the end socket underpart teflon pad 6 is housed, is used for the through hole in the sealed valve body 5.A screw is arranged in the upper end portion of end socket 7, the lower end of sliding sleeve 4 is tightened in this screw, the upper end of sliding sleeve 4 also has a screw, the screw rod of handle 1 end and this screw match to merge and are movably connected, when handle 1 drives the screw rod rotation, sliding sleeve 4 moves up and down with end socket 7 thereupon, can finish the open and close action of valve.Handle 1 is installed in the gland nut 3 of valve body 5 upper ends, is fixed by setscrew nut and locking nut.Gland nut 3 is tightened in the top of valve body 5 in the mode of screw thread.The central authorities of convolution diaphragm 8 are clamped by the junction between sliding sleeve 4 and the end socket 7, and the gland nut 3 that the edge of convolution diaphragm 8 is positioned at valve body 5 upper ends is pressed on the inner face of valve body 5.Described convolution diaphragm 8 adopts the elastomer diaphragm of interlayers to make, and its interlayer can be according to the varying in size of pressure, and the bore difference of valve adopts materials such as bright and beautiful silk, nylon wire, silk bolting silk, terylene, metallic sieve.Above the convolution diaphragm 8 limit position part is arranged in valve body 5, this limit position part is a stop collar 9 that is enclosed within the slide block outside, and it is fixed on the junction between gland nut 3 and the valve body 5, can limit the position that sliding sleeve moves up and down, and protection convolution diaphragm 8 is not destroyed.
In sum, the utility model is not only novel, and practical, and the modular design of its innovation but can Make this valve seal tight, do not have and leak, compare with background technology and have outstanding feature and progress, tool Patentability is arranged.
