Detailed Description

The following is only the preferred embodiment of the present invention, the protection scope is not limited to this embodiment, and all technical solutions belonging to the idea of the present invention should belong to the protection scope of the present invention. It should also be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and such modifications and decorations should also be regarded as the protection scope of the present invention.

As shown in fig. 1 to 3, a durable and stable valve seat comprises a mounting seat 1, an annular seat 2 matched with a valve ball, and a connecting sleeve 3 for fixing the mounting seat 1 and the annular seat 2.

One side of the mounting seat 1 is provided with an inner ring gap, and the annular seat 2 is arranged in the inner ring gap. Annular seat 2 all sets up arc surface 21 along two interior round edges of hole, and arc surface 21 makes through cutting to one side, grinding, and arc surface 21 is used for supporting the cooperation with the valve ball outer wall.

Two outer circle edges of the annular seat 2 are respectively provided with a first inclined plane 22, and an inner circle edge of the top surface of the inner ring notch is provided with a second inclined plane 1111. When the annular seat 2 is arranged in the inner ring gap, the first inclined surface 22 and the second inclined surface 1111 of the top surface form a first annular groove, and a first sealing ring 4 is arranged in the first annular groove. The first sealing ring 4 is used for ensuring the sealing performance between the annular seat 2 and the mounting seat 1, and in order to further improve the sealing performance, the mounting seat 1 comprises an annular outer wall 11 and a base 12, and the second inclined surface 1111 is arranged at the inner circle edge of the top surface of the annular outer wall 11; when the annular outer wall 11 is superposed on the base 12, the inner annular gap is formed between the outer wall and the top surface of the base 12; an inclined surface III 1121 is arranged on the inner circle edge of the bottom surface of the annular outer wall 11, an annular groove II is formed by the inclined surface I22 and the inclined surface III 1121 of the bottom surface, and a sealing ring II 5 is arranged in the annular groove I.

The connecting sleeve 3 comprises a sleeve ring part 31 and a limiting ring part 32. The sleeving ring part 31 is sleeved on the mounting seat 1 and detachably connected with the mounting seat 1. By combining the existing connection mode and the structure of the mounting base 1, preferably, the sleeve ring part 31 of the connecting sleeve 3 is provided with a plurality of mounting holes, and the outer wall of the base 12 is provided with a plurality of threaded holes corresponding to the mounting holes; the mounting hole is step-shaped, and after the connecting sleeve 3 and the annular seat 2 are connected through the bolt 6, the nut of the bolt 6 is positioned in the mounting hole, so that the valve seat can be conveniently matched with the valve body subsequently.

Firstly, the annular outer wall 11 is sleeved into the annular seat 2, the first sealing ring 4 is placed, then the sleeving ring part 31 is sleeved into the annular outer wall 11, the annular outer wall 11 and the annular seat 2 are turned over to abut against the limiting ring part 32, then the second sealing ring 5 is placed, finally the base 12 is inserted, the position is adjusted, and the sleeving ring part 31 and the base 12 are connected. At this moment, the spacing ring part 32 simultaneously supports the top surfaces of the mounting seat 1 and the annular seat 2 and extrudes the first sealing ring 4, and similarly, the base 12 simultaneously supports the bottom surfaces of the mounting seat 1 and the annular seat 2 and extrudes the second sealing ring 5.

When the arc surface 21 on one side of the annular seat 2 is matched with the valve ball for a long time and is worn, the mounting seat 1 can be disassembled, the annular seat 2 is turned over, the arc surface 21 on the other side is matched with the valve ball, and the durability is improved.

In addition, it can be seen that if there is a certain deviation in height between the annular seat 2 and the annular outer wall 11, the effect that the "limiting ring portion 32 simultaneously abuts against the top surfaces of the mounting seat 1 and the annular seat 2, and the base 12 simultaneously abuts against the bottom surfaces of the mounting seat 1 and the annular seat 2" is affected, so that the sealing performance of the first sealing ring 4 and the second sealing ring 5 is affected. Therefore, the annular outer wall 11 includes an upper portion 111 and a lower portion 112, the second inclined surface 1111 is disposed on the upper portion 111, the third inclined surface 1121 is disposed on the lower portion 112, and a plurality of springs 7 are disposed between the upper portion 111 and the lower portion 112. I.e. the annular faces of the upper 111 and lower 112 parts which are close to each other, are provided with a plurality of insertion holes into which the ends of the springs 7 are inserted. In this way, the above-mentioned effect can be easily achieved by the spring 7. The design of the annular outer wall 11 including the upper part 111 and the lower part 112 is combined, so that the upper part 111 and the lower part 112 have the same structural size, and one of the parts is designed and machined, so that the annular outer wall 11 can be combined.

In addition, the outer wall of the base 12 is provided with a third annular groove, a third sealing ring 8 is arranged in the third annular groove, a fourth annular groove is arranged on the outer wall of the sleeving connection ring part 31, and a fourth sealing ring 9 is arranged in the fourth annular groove, so that the sealing performance between the valve seat and the valve body is improved.
