The utility model discloses a kind of gas safety valve, this gas safety valve high safety can automatically be blocked combustion gas when fuel tube outlet port catches fire.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, Fig. 1 is the structural representation of the utility model gas safety valve.
A kind of gas safety valve, comprise suction valve 1 and gas outlet valve 2, described suction valve 1 and gas outlet valve 2 link into an integrated entity, both axial coincidences, described gas outlet valve 2 comprises Decompression valves 3, limiting board 4, piston column 5, elastic component 6, jacking block 7, piston mandril 8, meltable stop block 9 and the switch jacking block 10 being 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 interlocks, gas circuit disconnects; Described limiting board 4 is located on Decompression valves 3; On described elastic component 6 piston set posts 5, its one end is fixedly connected with the jacking block 7 on piston column 5, and the other end is fixedly connected with limiting board 4; Described piston column 5 one end are connected with piston mandril 8 through jacking block 7, and the other end is fixedly connected with lower half portion of Decompression valves 3 through limiting board 4 is rear;
Described switch jacking block 10 comprises supporting base 11 and contiguous block 12, and described supporting base 11 is installed on the inwall of gas outlet valve 2, and described contiguous block 12 is installed on supporting base 11, and the other end and piston mandril 8 are near an end in contact of 2 mouthfuls of gas outlet valves; Described meltable stop block 9 is located at piston mandril 8 both sides or integral body wraps piston mandril 8, and between piston mandril 8 and contiguous block 12 and the inwall of gas outlet valve 2, the piston mandril 8 that the obstruction by meltable stop block 9 makes and contiguous block 12 keep coupled condition.
When the gas safety valve that the utility model embodiment provides is normally worked, Decompression valves 3 two parts are in separated state up and down, combustion gas is inputted by suction valve 1, from gas outlet valve 2 output.When 2 mouthfuls of gas outlet valves catch fire, 2 mouthfuls of temperature of gas outlet valve rise, and make meltable stop block 9 melt distortion, and the resistance of 9 pairs of piston mandrils 8 of meltable stop block reduces, and piston mandril 8 departs from piston column end; Due to the movement of piston mandril 8 ends, make piston mandril 8 ends that prop up piston column 5 originally occur space, impel piston column 5 to the place's motion of above-mentioned space; Due to the movement of piston column 5, drive upper and lower two the part interlocks of Decompression valves 3 that gas circuit is disconnected, the input of blocking-up combustion gas, alleviates 2 mouthfuls of problems of catching fire of gas outlet valve.
From technique scheme, can find out, as shown in Figure 1, the gas safety valve that the utility model embodiment provides is simple in structure, but can effectively extinguish catching fire of 2 mouthfuls of gas outlet valves.By 2 mouthfuls of meltable stop block 9 perception gas outlet valves, catch fire, piston mandril 8 ends misplace, move is the motion slot milling of piston column 5, thereby elastic component 6 impels piston column 5 motions to drive upper and lower two the part interlocks of Decompression valves 3 that gas circuit is disconnected, and realizes the object of fire extinguishing by the input of blocking-up combustion gas.Meanwhile, it is spacing that the arranging of limiting board 4 can be carried out elastic component 6 according to the compression requirement of elastic component 6, also can to piston column 5 desired positions, arrange better, thereby can more accurately control the automatic blocking-up of combustion gas.Visible, the gas safety valve that the utility model provides can automatically be blocked combustion gas when fuel tube outlet port catches fire, and avoids explosive accident to occur, and guarantees user's safety.
Particularly, as shown in Figure 1, in the gas safety valve providing in the utility model embodiment, described piston mandril 8 comprises two sections of mutual flexible connection, and meltable stop block 9 is at least located at the both sides of this tie point of two sections, or wraps this tie point of two sections.When the valve port of giving vent to anger catches fire, the valve port temperature of giving vent to anger rises, make meltable stop block 9 melt distortion, the resistance of 9 pairs of piston mandrils 8 of meltable stop block reduces, because two sections of piston mandrils 8 are not fixedly connected with at point of contact place, when meltable stop block 9 resistances reduce, thereby piston mandril 8 more easily misplaces drive, move piston column 5 ends.
Particularly, as shown in Figure 1, in the gas safety valve providing in the utility model embodiment, at two sections of piston mandrils, 8 point of contact places, wherein the end of a section is cambered surface spill, the cambered surface convex of the end of another section for matching with spill.The concavo-convex structure matching of piston mandril 8 ends, can make two sections of piston mandrils 8 coordinate at point of contact place more firm.
Particularly, as shown in Figure 1, in the gas safety valve providing in the utility model embodiment, described piston mandril 8 is cambered surface spill near the end of 2 mouthfuls of gas outlet valves; Described contiguous block 12 is spherical for what match.Spherical contiguous block 12 can match better with piston mandril 8 ends, and can when the 8 dislocation separation of needs piston mandril, more easily move.
Particularly, as shown in Figure 1, in the gas safety valve providing in the utility model embodiment, at piston column 5 and piston mandril 8 point of contact places, one of them end is cambered surface spill, the cambered surface convex of another end for matching with spill.The touching position of piston column 5 ends and piston mandril 8 ends can more firmly match by the structure of concavo-convex cooperation.
Particularly, as shown in Figure 1, in the gas safety valve providing in the utility model embodiment, described elastic component 6 is spring.Choose spring as elastic component 6, not only simple in structure, material is common simultaneously, and cost is lower.
Particularly, as shown in Figure 1, in the gas safety valve providing in the utility model embodiment, the material of described meltable stop block 9 is paraffin, insect wax, foamed plastics or resin.Paraffin, insect wax, foamed plastics or resin etc. are all that heat easily melts material, when 2 mouthfuls of gas outlet valves catch fire, can shorten by rapid melting.
In order to realize gas safety valve, be connected with the tight of gas inlet pipe, as shown in Figure 1, in the gas safety valve providing in the utility model embodiment, the end of described suction valve 1 is provided with gas tank interface glue 13.The end of suction valve 1 is provided with gas tank interface glue 13, and the problem thereby the connecting end that can prevent gas safety valve and gas inlet pipe leaks air, further guarantees the Security that gas safety valve is used.
Meanwhile, in order further gas leakage situation to be detected, thereby can find fast and solve gas leakage problem, as shown in Figure 1, in the gas safety valve providing in the utility model embodiment, described safety valve is provided with gas detector, can detect detecting gas leakage situation.
Further, as shown in Figure 1, in the gas safety valve providing in the utility model embodiment, the outer wall of described suction valve 1 is provided with thermal-protective coating 14, in described thermal-protective coating 14, asbestos or sand is housed, and improves gas safety valve at the effect of heat insulation at suction port place.
