As shown in Figures 1, 2 and 3, a cavity is provided in the chamber wall of the air outlet chamber F1, and the ship Hx has an alarm device air shaft switch E, which includes a conductive disk, a conductive j contact E2, and a micro Pressing spring E3 and rubber film E4, through the fixing screw E24 = ring seal on the hole, read the rubber-shaped cover E22, and press the rubber film E4 under the rubber film cover E22, in the high rubber film The top of the pressure plate cover E22 has a hole, and a hole is formed in the rubber film E4 corresponding to the hole on the rubber film pressure plate cover E22, and a conductive ring is firmly inserted in the hole of the rubber film E4. The upper end of the rod E12 '忒 push rod E12 is fixed with a conductive plate E1 disposed on the rubber film pressure plate cover E22, and the push rod plate 3 is fixed at the lower end of the push rod E12, and the push rod plate Ei3 is placed thereon. Below the rubber film E4. A spring E24 and a fiber spring yellow pad E31 are further disposed on the push rod E12, the end of the spring E24 abuts against the inner side of the rubber film pressure plate cover E22, and the other end abuts against the micro pressure spring pad E31, and the micro pressure spring The pad is placed against the rubber film 8 M327435 E4 with two electrical contact connectors E2 on the outer upper end face of the rubber film plate cover E22. A conductive ring E11 is fixed to the lower surface of the conductive disk E1 located on the convex upper casing of the rubber film presser cover E22. The alarm work of the gas explosion-proof anti-shock automatic alarm safety device (valve) provided by the present invention is: · When the safety valve is in the normal working towel of the pipeline towel, the quantitative gas enters the intake chamber from the intake pipe s S3, hitting in the venting chamber through 阙σ L2, and finally discharging from the low-pressure mosquito tube F. In the venting chamber π, there is a certain amount of gas passing through 'there is a constant pressure.' Therefore, the rubber film E4 on the wall of the chamber of the venting chamber F1 is swollen outwards, and then the conductive ring fastened on the rubber film is driven. The push rod is also lifted up. 'The conductive ring E11 on the upper side is separated from the electrical contact joint 2 on the rubber cover plate' to make the circuit connecting the warning light c and the alarm D open. When the gas stove or the connected gas official road occurs in the domain, the amount of gas flowing through the valve increases, thereby causing the piston P to change the pressure difference, and the piston p =1 under the pressure difference The mouth L2 is closed; when an earthquake or shaking the casing, the door supports the piston p not to the veil of the pendulum __ ' _p, thereby making a live base? __ force difference changes, the pressure in the pressure Under the action, the piston P also closes the valve port L2. After the 2 port L2 is closed, the air pressure of the air outlet chamber μ will be lowered, and the air outlet (4) the red rubber ray will be lowered downward, and the tightening _ conductive ring push rod ει2 is also a plate cover. Ε2^ makes the upper nalai E1 of the push rod Ε12, which is placed on the upper end surface of the rubber film pressing conductive plate E1 and the rubber film pressing plate 9 M327435 on the upper end surface of the cover E22, and two electrical contacts The connector E2 is in contact, so that the above circuit is turned on. The warning light and the warning foot can be called an alarm. The bullet placed on the push rod m is a micro force (four) ' During normal ventilation, the rubber expands, causing the spring to be compressed - Tian Maosheng When P cuts off the gas source early, on the one hand, the rubber film shrinks and falls after there is no air pressure, and another 'elastic η is also under the putter. The function of the fall is to ensure that the circuit is connected. This type of gas explosion-proof and anti-risk automatic alarm safety device (inter) can be leaked in the cooker or official road or in the event of an earthquake or other dangerous situation, in addition to In addition to the gas source, it can automatically issue an alarm immediately to remind people to repair it in time, providing a safer and more reliable guarantee for the dragon gas. The pneumatic switch provided by the safety device and the structure in the valve housing make the alarm circuit part The gas passage part is completely isolated and safe and reliable to use. The above is the specific embodiment of the novel and the technical principle applied. Any equivalent based on the new square wire is threatened.
