Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a valve stem seal ring with good compression resistance effect comprises an annular main body 1, wherein the annular main body 1 is a polyethylene annular main body, the polyethylene has strong acid, strong base and high corrosion resistance, connecting grooves 2 are respectively formed in the front side, the rear side, the left side and the right side of the top end of the annular main body 1, the connecting grooves 2 are in a V shape, fixed blocks 3 are arranged above the connecting grooves 2, the tops of the four fixed blocks 3 are fixedly connected through sealing lip bodies 4, the bottom of each sealing lip body 4 is fixedly connected with the top of the annular main body 1 through a shock absorption pad 5, the compression resistance between each sealing lip body 4 and the annular main body 1 is improved by arranging the shock absorption pad 5, the connecting grooves at the bottom of the fixed blocks 3 penetrate through the connecting grooves 2 and extend into the connecting grooves, buffer springs 6 are fixedly connected to the left side and the right side of the fixed blocks 3 inside the, one end of the buffer spring 6, which is far away from the fixed block 3, is fixedly connected with a stabilizing block 7, one side of the stabilizing block 7, which is far away from the buffer spring 6, is fixedly connected with a movable block 8 matched with the connecting groove 2, one side of the movable block 8, which is close to the connecting groove 2, is contacted with the inner wall of the connecting groove 2, the friction force generated by the movable block 8 on the connecting groove 2 is smaller, so that the movable block 8 can move in the connecting groove 2, the bottom of the fixed block 3 is fixedly connected with a connecting block 9, the bottom of the connecting block 9 is fixedly connected with an extrusion spring 10, the bottom of the extrusion spring 10 is fixedly connected with the bottom of the inner wall of the connecting groove 2, the buffer spring 6 and the extrusion spring 10 have resilience, so that the pressure resistance is well achieved, and the buffer spring has good pressure resistance through the mutual matching of the connecting groove 2, the valve rod sealing ring has the advantages that the effect that the sealing ring is easy to resist compression is achieved, the problem that a common valve rod sealing ring is difficult to resist compression is solved, the compression resistance of the sealing ring is improved, the phenomenon that the valve rod sealing ring is damaged due to the fact that the valve rod sealing ring is extruded for a long time is avoided, the service life of the sealing ring is prolonged, and great convenience is brought to a user.

During the use, valve rod is opened valve water and is exerted pressure to the sealing lip body 4 through pressure, the sealing lip body 4 drives buffer spring 6 motion through fixed block 3, buffer spring 6 drives the movable block 8 through the firm piece 7 and moves in spread groove 2, make buffer spring 6 drive the flexible decompression motion of movable block 8 through the firm piece 7, fixed block 3 drives connecting block 9 downstream, connecting block 9 drives extrusion spring 10 downstream, through mutually supporting of buffer spring 6 and extrusion spring 10, thereby the pressure that water was applyed to the sealing washer has been reduced.
