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 gas outlet valve 2 comprises the elastic component I 3, piston switch 4, lyotrope push rod 5 and the fixture block 6 that set gradually along outgassing direction, described fixture block 6 is located at valve port 7 inwall of giving vent to anger, described lyotrope push rod 5 two ends contact with piston switch 4 respectively with inside fixture block 6, withstand piston switch 4; The two ends of described elastic component I 3 are installed on gas outlet valve end valve wall 8 and piston switch 4 respectively, and elastic component I 3 is in compressive state;
Described suction valve 1 comprises the Decompression valves 9, limiting board 10, piston column 11, the elastic component II 12 that set gradually along airintake direction; Described Decompression valves 9 is divided into upper and lower two parts, and during upper and lower two part occlusions, gas circuit disconnects; Described limiting board 10 is located on Decompression valves 9; On described elastic component II 12 piston set post 11, its one end is fixedly connected with the jacking block 13 on piston column 11, and the other end is fixedly connected with limiting board; Described piston column 11 one end contacts with piston switch 4 rear end, and the other end is fixedly connected with lower half portion of Decompression valves 9 through after limiting board 10.
When the gas safety valve that the embodiment of the present invention provides normally works, the elastic component II 12 being in compressive state makes piston column 11 open Decompression valves 9, and combustion gas is inputted by suction valve 1, exports from gas outlet valve 2.When valve port 7 of giving vent to anger catches fire, valve port 7 temperature of giving vent to anger rises, and lyotrope push rod 5 is melted and shortens, and it is close that the elastic component I 3 being at this moment in compressive state can promote the space of piston switch 4 after lyotrope push rod 5 shortens; Due to the movement of piston switch 4, piston switch 4 edge originally propping up piston column 11 is made to have occurred space, the elastic component II 12 being in compressive state impels piston column 11 to move upward at above-mentioned space place, thus drive the occlusion of Decompression valves about 9 two part that gas circuit is disconnected, block the input of combustion gas, alleviate the problem that valve port 7 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 7 of giving vent to anger.Caught fire by lyotrope push rod 5 perception valve port 7 of giving vent to anger, elastic component I 3 promotes piston switch 4 thereupon and moves rising slot milling into piston column 11, elastic component II 12 impels piston column 11 to rise thus drives the occlusion of Decompression valves about 9 two part that gas circuit is disconnected, and is realized the object of fire extinguishing by the input blocking combustion gas.Meanwhile, arranging of limiting board 10 can be carried out spacing to elastic component II 12 according to the compression requirement of elastic component II 12, also can arrange piston column 11 desired position better, 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 I 3 and elastic component II 12 are spring.Choose spring as elastic component, not only structure is simple, and material is common simultaneously, and cost is lower.
Particularly, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, control the length of lyotrope push rod 5, make the edge of piston switch 4 be positioned at the middle part of suction valve 1.The edge of piston switch 4 is arranged on the middle part of suction valve 1, enough distances can be left for the movement of piston switch 4 on the one hand, on the other hand also for the rising of piston column 11 leaves sufficient space.
Particularly, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, described lyotrope push rod 5 is two, is located at the upper and lower end of gas outlet valve inwall 14.The upper and lower end of gas outlet valve inwall 14 arranges two lyotrope push rods 5, can more firmly prop up fixture block 6 and piston switch 4 when gas safety valve normally works.
Particularly, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, the material of described lyotrope push rod 5 is paraffin, insect wax, foamed plastics or resin.Paraffin, insect wax, foamed plastics or resin etc. are all that heat easily melts material, can shorten by rapid melting when valve port 7 of giving vent to anger catches fire.
In order to realize the compact siro spinning technology of gas safety valve and gas inlet pipe, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, the end of described suction valve is provided with screw thread 15, thus can prevent the connecting end of gas safety valve and gas inlet pipe to leak air problem, guarantee the Security that gas safety valve uses.
In order to realize closely being connected of gas safety valve and gas inlet pipe, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, the end of described suction valve 1 is provided with gas tank interface glue 16.The end of suction valve 1 is provided with gas tank interface glue 16, thus can prevent the connecting end of gas safety valve and gas inlet pipe to leak air problem, guarantees the Security that gas safety valve uses further.
Meanwhile, in order to detect gas leakage situation further, thus can find fast and solve leakage problem, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, described safety valve is provided with gas detector, can detect detection gas leakage situation.
Further, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, the outer wall of described suction valve 1 is provided with thermal-protective coating 17, and described thermal-protective coating 17, built with asbestos or sand, improves the effect of heat insulation of gas safety valve at suction port place.
