[0024] The positioner valve sleeve 1 is internally provided with a valve core installation frame 5.

[0025] The positioner valve sleeve 1 further comprises a thread groove 101, a connecting ring 102 and a filter screen cover 103, the thread groove 101 is formed on the periphery of the positioner valve sleeve 1, the connecting ring 102 is fixedly installed at the lower end of the positioner valve sleeve 1, and the filter screen cover 103 is sleeved on the bottom end of the periphery of the connecting ring 102.

[0026] In the embodiment, the connecting ring 102 is provided with a rectangular groove structure in annular position distribution on the peripheral section close to the bottom, and the bottom and the side end of the filter screen cover 103 are provided with a hollow groove structure;The valve core installation frame 5 further comprises a limit sleeve 501, an adjusting peg 502, a one-way sealing ring 503 and a connection strip 504, the limit sleeve 501 is inserted into the middle part of the valve core installation frame 5, and the adjusting peg 502 and the limit sleeve 501 are integrally injection molded.

[0027] Specifically, as Figure 1 andFigure 2 As shown, the filter screen cover 103 is sleeved on the bottom of the connecting ring 102 after installation, and the hollow slots on the side ends of the connecting ring 102 and the filter screen cover 103 correspond to each other, which does not affect the circulation of the gas and can effectively prevent larger sundries from entering the gas port and causing blockage.

[0028] In the embodiment, the one-way sealing ring 503 is movably connected to the side end of the valve core mounting frame 5 through the connecting strip 504, the connecting strip 504 penetrates the valve core mounting frame 5 and is inserted into the inside of the limiting sleeve 501; two groups of strip-shaped protrusions are arranged at both ends of the limiting sleeve 501, and the strip-shaped protrusions are embedded in the inside of the displacement valve sleeve 1 and are in sliding connection with the displacement valve sleeve 1.

[0029] Specifically, as shown in Figure 3 and Figure 4 The strip-shaped protrusions on the outside of the limiting sleeve 501 can limit the position of the limiting sleeve 501, so that unnecessary position change can be avoided when the limiting sleeve 501 is inserted into the middle part of the displacement valve sleeve 1.

[0030] In the embodiment, a circular through slot is arranged in the middle part of the displacement valve sleeve 1, four groups of groove structures are arranged around the circular through slot, and the same grooves are arranged on the end face of the valve core mounting frame 5; the connecting band 2 is composed of a strip-shaped band structure and a ring-shaped rubber ring, the ring-shaped rubber ring is sleeved on the periphery of the displacement valve sleeve 1, and the end of the strip-shaped band is provided with a shaft structure movably connected to the side end of the sealing cover 3.
