Detailed description of the invention
The invention discloses a kind of gas safety valve, this gas safety valve high safety, it is possible to automatically block combustion gas when Gas Pipe exit catches fire.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to the structural representation that Fig. 1, Fig. 1 are gas safety valves of the present invention.
A kind of gas safety valve, including intake valve 1 and air outlet valve 2, described intake valve 1 and air outlet valve 2 link into an integrated entity, both is axially coincident, and described air outlet valve 2 includes relief valve 3, limiting plate 4, piston boit 5, elastic component 6, jacking block 7, piston mandril 8, meltable stop block 9 and the switch jacking block 10 set gradually by air inlet to outgassing direction；
Described relief valve 3 is divided into upper and lower two parts, and during upper and lower two part occlusions, gas circuit disconnects；Described limiting plate 4 is located on relief valve 3；On described elastic component 6 piston set post 5, its one end is fixing with the jacking block 7 on piston boit 5 to be connected, and the other end is fixing with limiting plate 4 to be connected；Described piston boit 5 one end is connected through jacking block 7 with piston mandril 8, and the other end is fixing with the latter half of relief valve 3 after passing limiting plate 4 to be connected；
Described switch jacking block 10 includes supporting seat 11 and contiguous block 12, and described support seat 11 is installed on the inwall of air outlet valve 2, and described contiguous block 12 is installed on support seat 11, and the other end and piston mandril 8 are near the end thereof contacts of air 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 the inwall of piston mandril 8 and contiguous block 12 and air outlet valve 2, the piston mandril 8 and the contiguous block 12 that are made by the obstruction of meltable stop block 9 keep connection status.
The gas safety valve that the embodiment of the present invention provides is when normally working, relief valve 3 up and down two be partially in released state, combustion gas is inputted by intake valve 1, exports from air outlet valve 2.When air outlet valve 2 mouthfuls catches fire, 2 mouthfuls of temperature of air outlet valve rise, and make meltable stop block 9 melt deformation, and the resistance of piston mandril 8 is reduced by meltable stop block 9, and piston mandril 8 deviates piston boit end；Movement due to piston mandril 8 end so that piston mandril 8 end originally propping up piston boit 5 occurs in that space, promotes piston boit 5 to move at above-mentioned space；Due to the movement of piston boit 5, drive relief valve about 3 two part occlusion that gas circuit is disconnected, block the input of combustion gas, alleviate 2 mouthfuls of problems caught fire of air outlet valve.
From technique scheme it can be seen that as it is shown in figure 1, the gas safety valve simple in construction of embodiment of the present invention offer, but can effectively extinguish catching fire of air outlet valve 2 mouthfuls.Caught fire by meltable stop block 9 perception air outlet valve 2 mouthfuls, the dislocation of piston mandril 8 end, the mobile motion slot milling for piston boit 5, elastic component 6 promotes piston boit 5 to move thus drives relief valve about 3 two part occlusion that gas circuit is disconnected, and realizes the purpose of fire extinguishing by blocking the input of combustion gas.Meanwhile, elastic component 6 can be carried out spacing according to the compression requirement of elastic component 6 by arranging of limiting plate 4, also preferably can be configured piston boit 5 desired position such that it is able to more precisely controls the automatic blocking-up of combustion gas.Visible, the gas safety valve that the present invention provides can automatically block combustion gas when Gas Pipe exit catches fire, it is to avoid explosion accident occurs, it is ensured that the safety of user.
Specifically, as it is shown in figure 1, in the gas safety valve that the embodiment of the present invention provides, described piston mandril 8 includes two sections be mutually flexibly connected, and meltable stop block 9 is at least located at the both sides of this junction point of two sections, or wraps this junction 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 deformation, the resistance of piston mandril 8 is reduced by meltable stop block 9, connect owing to two sections of piston mandrils 8 are not fixing at contact point, when meltable stop block 9 resistance reduces, piston mandril 8 is more easy to dislocation thus drives piston boit 5 end to move.
Specifically, as it is shown in figure 1, in the gas safety valve that the embodiment of the present invention provides, at two sections of piston mandril 8 contact points, 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, it is possible to make two sections of piston mandrils 8 coordinate at contact point more firm.
Specifically, as it is 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 air outlet valve 2 mouthfuls；Described contiguous block 12 is spherical for match.Can preferably match with piston mandril 8 end for ball-joint piece 12, and can be more easy to when needs piston mandril 8 dislocation separates mobile.
Specifically, as it is shown in figure 1, in the gas safety valve that the embodiment of the present invention provides, at piston boit 5 with piston mandril 8 contact point, one of them end is cambered surface spill, and another end is the cambered surface convex matched with spill.Can more securely be matched by the structure of male-female engagement with the touching position of piston mandril 8 end in piston boit 5 end.
Specifically, as it is shown in figure 1, in the gas safety valve that the embodiment of the present invention provides, described elastic component 6 is spring.Choosing spring as elastic component 6, be not only simple in structure, material is common simultaneously, and cost is relatively low.
Specifically, as it is 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, foam plastics or resin.Paraffin, insect wax, foam plastics or resin etc. are all that heat easily melts material, can shorten by rapid melting when air outlet valve 2 mouthfuls catches fire.
In order to realize the compact siro spinning technology of gas safety valve and gas inlet pipe, as it is shown in figure 1, in the gas safety valve that the embodiment of the present invention provides, the end of described intake valve 1 is provided with gas tank interface glue 13.The end of intake valve 1 is provided with gas tank interface glue 13 such that it is able to prevents gas safety valve from leakage problem occur with the connection end of gas inlet pipe, further ensures that the safety that gas safety valve uses.
Meanwhile, in order to further gas leakage situation be detected such that it is able to quickly find and solve leakage problem, as shown in Figure 1, in the gas safety valve that the embodiment of the present invention provides, described relief valve is provided with detector, it is possible to detect detection gas leakage situation.
Further, as it is shown in figure 1, in the gas safety valve that the embodiment of the present invention provides, the outer wall of described intake valve 1 is provided with thermal insulation layer 14, described thermal insulation layer 14, built with asbestos or sand, improves gas safety valve effect of heat insulation at air inlet.
