Embodiment
The invention discloses a kind of gas safety valve, this gas safety valve high safety, automatically can block combustion gas when fuel tube outlet port catches fire.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, Fig. 1 is the structural representation of gas safety valve of the present invention.
A kind of gas safety valve that the embodiment of the present invention provides, comprise suction valve 1 and gas outlet valve 2, described suction valve 1 and gas outlet valve 2 link into an integrated entity, both axis overlap, and described gas outlet valve 2 comprises the Decompression valves 3, limiting board 4, piston column 5, elastic component 6, pad 7, lyotrope push rod 8 and the fixture block 9 that are set gradually to outgassing direction by air inlet; Described Decompression valves 3 is divided into upper and lower two parts, and during upper and lower two part occlusions, gas circuit disconnects; Described limiting board 4 is located on Decompression valves 3; On described elastic component 6 piston set post 5, its one end is fixedly connected with the pad 7 on piston column 5, and the other end is fixedly connected with limiting board 4; Described piston column 5 one end is fixedly connected with pad 7, and the other end is fixedly connected with lower half portion of Decompression valves 3 through after limiting board 4; Described fixture block 9 is located at valve port 10 inwall of giving vent to anger, and described lyotrope push rod 8 two ends contact with pad 7 respectively with inside fixture block 9, withstand pad 7.
When the gas safety valve that the embodiment of the present invention provides normally works, two parts up and down of Decompression valves 3 are in separated state, and combustion gas is inputted by suction valve 1, exports from gas outlet valve 2.When valve port 10 of giving vent to anger catches fire, valve port 10 temperature of giving vent to anger rises, and lyotrope push rod 8 is melted and shortens, and the elastic component 6 being at this moment in compressive state can promote pad 7 and the space of piston rod after lyotrope push rod 8 shortens is close; Due to the movement of piston column 5, drive the occlusion of Decompression valves about 3 two part that gas circuit is disconnected, block the input of combustion gas, alleviate the problem that valve port 10 of giving vent to anger catches fire.
As can be seen from technique scheme, as shown in Figure 1, the gas safety valve arrangement that the embodiment of the present invention provides is simple, but effectively can extinguish catching fire of valve port 10 of giving vent to anger.Caught fire by lyotrope push rod 8 perception valve port 10 of giving vent to anger, elastic component 6 promotes pad 7 thereupon and moves mobile slot milling into piston column 5, thus drive the occlusion of Decompression valves about 3 two part that gas circuit is disconnected, the object of fire extinguishing is realized by the input blocking combustion gas.Meanwhile, arranging of limiting board 4 can be carried out spacing to elastic component 6 according to the compression requirement of elastic component 6, also can arrange piston column 5 desired position better, controls the opening and closing of Decompression valves 3, thus more accurately can control the automatic blocking-up of combustion gas.Visible, gas safety valve provided by the invention can block combustion gas automatically when fuel tube outlet port catches fire, and avoids explosive accident to occur, and ensures the safety of user.
Particularly, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, described elastic component 6 is spring.Choose spring as elastic component 6, not only structure is simple, and material is common simultaneously, and cost is lower.
