When the sealing gasket is used for sealing connection between the valve and the natural gas pipeline, at least the following two methods are installed on the sealing gasket. The first installation method comprises the following steps: the sealing gasket is assembled firstly, then the valve, the sealing gasket and the natural gas pipeline are connected in sequence, and finally the sealing gasket is tightly squeezed in a gap between the valve and the natural gas pipeline, so that the sealing connection of the valve and the natural gas pipeline is realized. And a second installation method: the valve is connected with the natural gas pipeline and a gap for installing the sealing gasket is reserved, then the sealing gasket is assembled in the gap, and then the valve is further connected with the natural gas pipeline to tightly press the sealing gasket between the valve and the natural gas pipeline, so that the sealing connection between the valve and the natural gas pipeline is realized.
When the sealing gasket is aged or damaged and the like and needs to be replaced, the valve and the natural gas pipeline are firstly loosened, the valve and the natural gas pipeline are not required to be disassembled, then the second sealing ring 2 is stretched to take out the second sealing ring 2 from the connecting groove 11 of the first sealing ring 1, at the moment, the first sealing ring 1 can be split into two sealing strips 3 and taken down, so that the sealing gasket is integrally taken down from the valve and the natural gas pipeline, and finally, a new sealing gasket is filled into a gap between the valve and the natural gas pipeline according to the second installation method, and replacement of the sealing gasket is completed.
The sealing strip 3 includes extrados, intrados, two terminal surfaces and two arc planes, and the terminal surface of sealing strip 3 is the equipment butt joint face between the sealing strip 3, and the arc plane of sealing strip 3 is the one side towards valve or towards natural gas line, and the breach 34 of intercommunication spread groove 11 is seted up to one of them arc plane outward flange of sealing strip 3, and the seting up of breach 34 is convenient for people to utilize finger or instrument to take out the second sealing washer 2 that is located the spread groove 11. Further, the notch 34 is an arc-shaped opening, and in other embodiments, the notch 34 may be a square opening, a special-shaped opening, etc., as long as the effect of facilitating the removal of the second sealing ring 2 can be achieved.
One of them terminal surface of sealing strip 3 is provided with the inserted block 35 an organic whole, and the jack 36 has been seted up to the other terminal surface, and the inserted block 35 and the jack 36 between two sealing strips 3 are used for peg graft in a one-to-one correspondence, and the second sealing washer 2 is sheathe in again after two sealing strips 3 peg graft each other and form first sealing washer 1, and the separation along self axis direction between two sealing strips 3 can be restricted to inserted block 35 and jack 36 to improve the stability that first sealing washer 1 kept assembled state.
The outer edges of the first caulking groove 31 are all provided with chamfer surfaces, so that the notch of the first caulking groove 31 is flaring from inside to outside, and the second sealing ring 2 is conveniently embedded into the connecting groove 11 formed by the first caulking groove 31.
The second sealing ring 2 comprises an outer cambered surface, an inner cambered surface and two arc-shaped planes, wherein the distance between the outer cambered surface and the inner cambered surface of the second sealing ring 2 is the thickness of the second sealing ring 2, and the distance between the two arc-shaped planes of the second sealing ring 2 is the width of the second sealing ring 2. The groove depth of the first caulking groove 31 is larger than or equal to the thickness of the second sealing ring 2, so that the second sealing ring 2 is ensured to be completely embedded into the connecting groove 11 formed by the first caulking groove 31, and the outer cambered surface of the second sealing ring 2 cannot be protruded on the outer cambered surface of the first sealing ring 1, thereby ensuring the overall flatness of the periphery of the sealing ring. The width of the first caulking groove 31 is smaller than or equal to the width of the second sealing ring 2, so that the second sealing ring 2 can be squeezed into the connecting groove 11 formed by the first caulking groove 31, thereby improving the stability of the first sealing ring 1 when the first sealing ring 1 is kept in an assembled state, in addition, the second sealing ring 2 enables the connecting groove 11 to have a trend of outwards expanding, thereby enabling the first sealing ring 1 to have a trend of propping against a valve and a natural gas pipeline, and improving the sealing performance of the sealing gasket.
