Abstract
The utility model discloses a safety fuel gas valve. The valve body of the safety fuel gas valve is provided with an air inlet hole and an air outlet hole, wherein the air inlet hole is arranged on one side of the valve body and a regulating rod with the air outlet hole is arranged on the other side of the valve body; the rear end of the valve body is provided with a sealing rod with a sealing ring; the rear end of the sealing rod is matched with a top spring and the front end of the sealing rod passes through an annular hole on the front end of a fixed tube to be pressed against a piston with a sealing ring; and the piston cooperates with a positioning device. The positioning mechanism consists of a pressure spring and a clamping block, wherein the clamping block is arranged on the side face of the piston; the lower end of the clamping block is connected with the pressure spring; the middle part of the piston is provided with a clamping groove matched with the clamping block. The air outlet hole is positioned on the front end of the regulating rod and has a water drop shape. In the utility model, when the fuel gas pressure is overhigh, the piston can move to drive the sealing rod to move together and the sealing ring on the sealing rod can seal the air cavity to block the fuel gas channel, so the fuel gas valve can close automatically and the safety is high.
Description
Technical field:
The utility model relates to the gas range technical field, especially relates to the gas valve that uses on a kind of gas range.
Background technique:
Gas range all is provided with gas valve, and combustion gas enters from the air inlet position of gas valve, exports from air outlet hole.Owing to the excessive situation of gaseous-pressure may occur in the gas valve using process,, will cause very big potential safety hazard, and there is design deficiency in this respect in existing gas valve as untimely throttle down.
The model utility content:
The purpose of this utility model is to provide a kind of safety type gas valve at the deficiency of prior art existence, and it can be closed when gaseous-pressure is excessive automatically, and Security is higher.
For achieving the above object, safety type gas valve of the present utility model, its valve body is provided with inlet hole and air outlet hole, wherein, inlet hole is arranged on valve body one side, and the opposite side of valve body is provided with the adjustable lever of taking pore out of, the valve body rear end is provided with the seal bar of a band seal ring, the seal bar rear end cooperates with the top spring, and the looping pit that its front end passes the fixed tube front end withstands on the piston of band seal ring, and piston is combined with a location mechanism simultaneously.
Described positioning means is made of stage clip and fixture block, and wherein, fixture block is arranged at the piston side, and its lower end links to each other with stage clip, and the piston middle part offers the draw-in groove that cooperates with fixture block.
Described air outlet hole is positioned at the adjustable lever front end, and is drops.
The beneficial effects of the utility model are: it is when the excessive situation of gaseous-pressure occurring, and piston is removable, and seal bar is moved thereupon, seal ring on it can seal air cavity, block blast tube, thereby reach the purpose of automatic self-closing gas valve, Security is very good.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is a sectional structure chart of the present utility model;
Accompanying drawing 2 rotates sectional structure chart behind 45 degree for the utility model;
Accompanying drawing 3 is an adjustable lever structural representation of the present utility model.
Embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in the accompanying drawing 1: safety type gas valve of the present utility model, its valve body 10 is provided with inlet hole 11 and air outlet hole 12, wherein, inlet hole 11 is arranged on valve body 10 1 sides, the opposite side of valve body 10 is provided with the adjustable lever 20 of taking pore 21 out of, when the air outlet hole 21 of rotary regulating lever 20 on it and air outlet hole 12 were relative, combustion gas can be discharged from air outlet hole 12.Valve body 10 rear ends are provided with the seal bar 30 of a band seal ring 31, seal bar 30 rear ends cooperate with top spring 42, the looping pit 31 that its front end passes fixing rod 30 front ends withstands on the piston 50 of band seal ring 51, piston 50 is combined with a location mechanism simultaneously, this positioning means is made of stage clip 61 and fixture block 62, and wherein, fixture block 62 is arranged at piston 50 sides, its lower end links to each other with stage clip 61, and piston 40 middle parts offer the draw-in groove 52 that cooperates with fixture block 62.
The utility model in use, when the excessive situation of gaseous-pressure occurring, the pressure of combustion gas rushes at the seal ring 51 on the piston 50, promotes piston 50 integral body and moves right; When moving to certain position, the elastic force effect that fixture block 62 is subjected to stage clip 61 makes progress jack-up and snaps in the draw-in groove 52 of piston 50 sides.Simultaneously, seal bar 40 drives seal ring 41 and also moves right, and seal ring 41 is sealed looping pit 31, and air cavity is sealed, and blast tube is blocked, thereby reaches the purpose of automatic self-closing gas valve.
