Embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see that Fig. 1 is to shown in Figure 2:
The utility model is a kind of combustion gas earthquake stop valve, comprise valve body 10 and valve gap 20, valve body 10 bottoms are fuel gas inlet, the top is a gas outlet, is installed on the valve rod 30 on the valve gap 20, and described valve rod 30 1 ends are connected with the seal arrangement 40 that is positioned at valve body 10, the other end is connected with reseting handle 60 and seismic sensor cable device 50, have big spring 70 between described valve gap 20 and the seal arrangement 40, described big spring 70 1 ends withstand on the seal arrangement 40, and the other end withstands on the valve gap 20.After in the total pipeline in the present gas energy transporting system combustion gas earthquake stop valve of the present utility model being installed, under the normal condition, combustion gas earthquake stop valve is held open state, the gas energy can be passed through swimmingly, and when violent earthquake takes place, seismic sensor cable device 50 perception vibrations, react, combustion gas earthquake stop valve is closed, stop gas delivery, the gas that does not have after lateral is wrecked to continue is discharged, and avoids taking place poisoning or explosive accident because of gas leakage causes, and the while can also be avoided energy waste.
It below is the specific embodiment of described seismic sensor cable device 50.Described seismic sensor cable device 50 comprises the ball cover 51 that is installed on the valve gap 20, is positioned at spheroid 52, sliding sleeve 53, lever seat 54, lever 55, lever shaft 56 and the little spring 57 of ball cover 51; Described spheroid 52 is arranged on the sliding sleeve 53, described sliding sleeve 53 is arranged on the described lever seat 54, described lever 55 is articulated in the described lever seat 54 by lever shaft 56, and described lever 55 1 ends withstand on described sliding sleeve 53 bottoms, and the other end is connected in described valve rod 30; Described little spring 57 is sheathed on lever seat 54 outsides, and the top of little spring 57 connects sliding sleeve 53, below connection valve gap 20.Described valve rod 30 is provided with valve rod groove 31, and the lower end of described lever 55 is stuck in the valve rod groove 31.The working principle of seismic sensor cable device 50 is as follows, under the normal condition, it is static that sliding sleeve 53 keeps under the elastic force of little spring 57 and frictional force double action, lever 55 also keeps original position, therefore the end of lever 55 is stuck in the valve rod groove 31 of valve rod 30, makes valve rod 30 remain on the position of close valve gap 20, and this moment, big spring 70 was in compressive state, therefore seal arrangement 40 is in the position of leaving gas channel in the valve body 10, makes smooth and easy the passing through of gas energy.When earthquake takes place when, combustion gas earthquake stop valve itself also can shake thereupon, make spheroid 52 in ball cover 51, produce irregular rocking, when shaking, spheroid 52 can repeatedly clash into sliding sleeve 53 downwards, the elastic force and the frictional force that make sliding sleeve 53 overcome little spring 57 move down, sliding sleeve 53 can promote lever 55 like this, lever 55 can be around lever shaft 56 rotations under this thrust, an end that makes lever 55 be connected in valve rod 30 is thrown off in the valve rod groove 31 of valve rod 30, valve rod 30 can go deep in valve body 10 under the elastic force of big spring 70, seal arrangement 40 is got lodged in the gas channel in the valve body 10 block gas delivery, can when earthquake takes place, cut off the conveying of the gas energy automatically like this.
It below is the specific embodiment of described seal arrangement 40.Described seal arrangement 40 comprises rubber sleeve 41, sealing gasket 42, the jump ring 43 that is sheathed on valve rod 30 1 ends successively; Described big spring 70 1 ends withstand on the described valve gap 20, and the other end withstands on the described sealing gasket 42; Described sealing gasket 42 is sheathed on opening diameter on the valve rod 30 less than the external diameter of described jump ring 43; Described jump ring 43 is stuck in the draw-in groove 32 that described valve rod 30 ends offer.Jump ring 43 is stuck in the draw-in groove 32 of valve rod 30, make jump ring 43 and valve body 10 be fixed into one, sealing gasket 42 is pressed close to jump ring 43, jump ring 43 stops sealing gasket 42 to be taken off from valve rod 30, rubber sleeve 41 is between sealing gasket 42 and valve gap 20, and big spring 70 is sheathed on the rubber sleeve 41, and big spring 70 can be withstood on sealing gasket 42 and the valve gap 20 exactly, like this in the seal arrangement 40 all parts all with valve rod 30 structure that fuses, all can follow valve rod 30 and move together.
When earthquake needs to recover the gas energy supply later, combustion gas earthquake stop valve need be resetted.Therefore on the valve rod 30 reseting handle 60 is installed, described reseting handle 60 is by being threadedly connected to an end of valve rod 30, when resetting, only reseting handle 60 need be pulled out a part from valve gap 20, make valve rod 30 motions, valve rod 30 is blocked by lever 55 again, big spring 70 is in compressive state, and seal arrangement 40 withdraws from the gas channel of valve body 10.Gas in the valve body 10 can smooth and easyly be carried again like this.
Accurate in order to guarantee 50 work of seismic sensor cable device, when being installed, combustion gas earthquake stop valve need guarantee that seismic sensor cable device 50 is in vertical position as far as possible, therefore be equipped with at described valve gap 20 outer surfaces and weigh down chain 80 and weigh down frame 90, described bob chain 80 is interspersed on the described bob frame 90 vertically, can judge whether seismic sensor cable device 50 is installed on vertical position by weighing down the situation that chain 80 hangs down.
Combustion gas earthquake stop valve of the present utility model can make fuel gas transportation pipeline avoid suffering poisoning or explosive accident because of gas leakage causes behind the eaerthquake damage when earthquake takes place, and can also avoid energy waste simultaneously.
