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, 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, jacking block 7, piston mandril 8, meltable stop block 9 and the switch jacking block 10 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 jacking block 7 on piston column 5, and the other end is fixedly connected with limiting board 4; Described piston column 5 one end is 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 after limiting board 4;
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 the end thereof contacts of gas outlet valve 2 mouthfuls; Described meltable stop block 9 is located at piston mandril 8 both sides or entirety wraps piston mandril 8, and between piston mandril 8 and the inwall of contiguous block 12 and gas outlet valve 2, the piston mandril 8 made by the obstruction of meltable stop block 9 and contiguous block 12 keep coupled condition.
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 gas outlet valve 2 mouthfuls catches fire, gas outlet valve 2 mouthfuls of temperature rise, and make meltable stop block 9 melt distortion, and the resistance of meltable stop block 9 pairs of piston mandrils 8 reduces, and piston mandril 8 departs from piston column end; Due to the movement of piston mandril 8 end, make piston mandril 8 end originally propping up piston column 5 occur space, impel piston column 5 to move to above-mentioned space place; 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 gas outlet valve 2 mouthfuls of problems of catching 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 gas outlet valve 2 mouthfuls.Caught fire by meltable stop block 9 perception gas outlet valve 2 mouthfuls, the dislocation of piston mandril 8 end, the mobile motion slot milling for piston column 5, elastic component 6 impels piston column 5 to move thus drives the occlusion of Decompression valves about 3 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 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, 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 piston mandril 8 comprises two sections that are mutually flexibly connected, 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 valve port of giving vent to anger catches fire, valve port temperature of giving vent to anger rises, meltable stop block 9 is made to melt distortion, the resistance of meltable stop block 9 pairs of piston mandrils 8 reduces, because two sections of piston mandrils 8 are not fixedly connected with at point of contact place, when meltable stop block 9 resistance reduces, piston mandril 8 more easily misplaces thus drives piston column 5 end to move.
Particularly, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, at two sections of piston mandril 8 point of contact places, wherein the end of a section is cambered surface spill, and the end of another section is the cambered surface convex matched with spill.The concavo-convex structure matched of piston mandril 8 end, 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 that the embodiment of the present invention provides, described piston mandril 8 is cambered surface spill near the end of gas outlet valve 2 mouthfuls; Described contiguous block 12 is spherical for what match.Spherical contiguous block 12 can match better with piston mandril 8 end, and can the more easily movement when needs piston mandril 8 misplaces separation.
Particularly, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, at piston column 5 and piston mandril 8 point of contact place, one of them end is cambered surface spill, and another end is the cambered surface convex matched with spill.Can more firmly be matched by the structure of male-female engagement with the touching position of piston mandril 8 end in piston column 5 end.
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.
Particularly, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, 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, can shorten by rapid melting when gas outlet valve 2 mouthfuls 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 1 is provided with gas tank interface glue 13.The end of suction valve 1 is provided with gas tank interface glue 13, 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 14, and described thermal-protective coating 14, built with asbestos or sand, improves the effect of heat insulation of gas safety valve at suction port place.
