Embodiment 1

[0050] Such as Figures 3 to 4 As shown, the push-type valve includes a valve seat 201, a valve cavity 202 is provided in the middle of one side of the valve seat 201, and one end of the push-type structure is inserted. The first air port 203 and the second air port 204 are respectively opened, and the first air port 203 and the second air port 204 communicate with the valve cavity 202 through the first connection hole 205 and the second connection hole 206 located inside the valve seat 201 respectively, and the push type structure When not pressed, the first connecting hole 205 and the second connecting hole 206 are not connected, and when pressed, the first connecting hole 205 and the second connecting hole 206 are sealed and connected.

[0051] Preferably, the first air port 203 and the second air port 204 are respectively connected to the first external short pipe 225 and the second external short pipe 226 through connecting threads in the first air port, which facilitates...

Embodiment 2

[0058] This embodiment is basically the same as Embodiment 1, except that the elastic reset assembly also includes an elastic sealing cover 210 arranged between the valve seat 201 and the pressing valve stem 207 to prevent gas leakage in the valve chamber 202, and reset The spring 209 is arranged in the elastic sealing cover 210 , and presses the valve rod 207 to seal the cover sealing hole 211 passing through the elastic sealing cover 210 .

[0059] It should be noted that, due to the setting of the elastic sealing cover 210 at this time, one end of the return spring 209 does not need to be fixed on the pressing valve stem 207, and it can be sleeved on the pressing valve stem 207 to realize the pressure on the pressing valve stem 207. It can move freely, which greatly facilitates the disassembly and assembly of the return spring 209, because its moving position is limited by the elastic sealing cover 210 in this embodiment.

[0060] In addition, the elastic return assembly ca...

Embodiment 3

[0065] Such as Figures 3 to 6 As shown, this embodiment is basically the same as Embodiments 1 and 2, except that the push-type structure here also includes at least a part of the valve stem seat 217 located in the valve cavity 202 on the valve seat 201, and the valve stem seat 217 There is a valve stem channel 218 for a section of the pressing valve stem 207 to move back and forth inside, and the position where the first sealing member 208 is provided on the pressing valve stem 207 protrudes out of the valve when the pressing valve stem 207 is pressed and when it is not pressed. The stem seat 217 is inserted into the valve chamber 202, and the first sealing member 208 abuts against the opposite inner end of the stem seat 217 when it is not pressed to block the communication between the stem passage 218 and the second connecting hole 206. The stem passage 218 One side is opened with a first connecting channel 219 communicating with the first connecting hole 205, and the first...

Abstract

The invention provides a safety system for preventing gas leakage and explosion, and belongs to the technical field of gas conveying control equipment. The problems of complex structure, complex internal operation and the like in the prior art are solved. The safety system for preventing gas leakage and explosion is arranged between combustion equipment and a gas main pipeline which is communicated with the combustion equipment and is used for conveying gas, and comprises a gas valve arranged on the gas main pipeline, the safety system further comprises a gas exhaust pipe which is connected tothe position, located between the gas valve and the combustion equipment, of the gas main pipeline, communicates with the gas main pipeline and is used for discharging gas located in the position ofthe gas main pipeline. The safety system for preventing gas leakage and explosion has the advantages that one of the gas valve and the gas explosion-proof valve is selectively pressed through left-right swing of the swing arm on the electric swing assembly to selectively control one of the gas valve and the gas explosion-proof valve to be in an open state, the safety system is simple in structure,convenient to operate and control, good in sealing performance, good leakage-proof and explosion-proof effect, and convenient, safe and reliable to use.

Description

technical field [0001] The invention belongs to the technical field of gas transmission control equipment, and in particular relates to a gas leakage and explosion prevention safety system installed at a gas use end. Background technique [0002] Existing gas use ends, such as combustion equipment such as gas stoves, the valves on it are mainly used to allow the gas in the main gas pipeline to flow out for the ignition of the gas stove when the main gas pipeline and the gas stove are in a normal state where the seal connection is intact. Or block the gas in the gas main pipeline from flowing out to the gas cooker, but when the gas in the gas main pipeline is in an abnormal state (that is, a dangerous state, specifically as the gas in the gas main pipeline leaks onto the gas cooker, more dangerously, such as leaking to When the gas on the gas cooker is at or close to the gas explosion critical point), how to get rid of the gas flowing out from the gas main pipeline to the gas...
