In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a valve rod O type ring seal structure, its structure includes the valve rod body, O type ring, valve rod body outer wall is located to the O type ring, O type ring inboard is equipped with the spout, the inside slider that corresponds with the spout that is equipped with of valve rod body, the inside convenient structure of dismantling that is equipped with of valve rod body, convenient dismantlement structure includes depression bar, reset spring, linkage piece, transfer line, the depression bar outside is located to the linkage piece, linkage piece lower extreme is equipped with first slope, the transfer line is L type structure, transfer line wherein one end upper portion is equipped with the second slope and is connected with the laminating of first slope, the transfer line other end is connected with O type ring, be equipped with the slide channel corresponding with the transfer line in the valve rod body, reset spring locates the L type structure right angle inboard of transfer line.

Furthermore, the pressure lever is movably connected with the valve lever body.

Furthermore, the outer wall of the valve rod body is provided with an embedded groove corresponding to the O-shaped ring.

The utility model has the advantages that: be equipped with the sliding tray in O type ring inboard to and be equipped with the sliding block that carries out the restriction to the sliding tray on the valve rod, prevent effectively that the valve rod is in the assembling process, the O type ring groove of O type ring roll-out valve rod has improved the convenience of staff's assembly, still is equipped with the convenient structure of dismantling the O type ring in the valve rod simultaneously, has further improved the convenience of staff's maintenance.

Drawings

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

fig. 1 is a schematic structural view of an O-ring sealing structure of a valve stem according to the present invention;

fig. 2 is the utility model discloses a valve rod O type ring seal structure's section structure sketch map.

In the figure: the valve rod body-1, the O-shaped ring-2, the sliding groove-4, the sliding block-5, the compression bar-3, the reset spring-6, the linkage block-7 and the transmission rod-8.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 and 2, the present invention provides a sealing structure for a valve rod O-ring, which comprises: the structure of the valve comprises a valve rod body 1 and an O-shaped ring 2, wherein the O-shaped ring 2 is arranged on the outer wall of the valve rod body 1, a sliding groove 4 is arranged on the inner side of the O-shaped ring 2, a sliding block 5 corresponding to the sliding groove 4 is arranged inside the valve rod body 1, a convenient and fast dismounting structure is arranged inside the valve rod body 1 and comprises a pressing rod 3, a reset spring 6, a linkage block 7 and a transmission rod 8, the linkage block 7 is arranged on the outer side of the pressing rod 3, a first inclined part is arranged at the lower end of the linkage block 7, the transmission rod 8 is of an L-shaped structure, a second inclined part is arranged at the upper part of one end of the transmission rod 8 and is connected with the first inclined part in a laminating manner, the other end of the transmission rod 8 is connected with the O-shaped ring 2, a sliding channel corresponding to the transmission rod 8 is arranged in the valve rod body 1, the, and an embedded groove corresponding to the O-shaped ring 2 is formed in the outer wall of the valve rod body 1.

For example, in the assembly process, the valve rod body 1 is fitted into the valve body, in the fitting process, when the valve rod body 1 is carelessly contacted with the inner wall of the valve, the O-ring 2 is turned over by the acting force of the inner wall, in the turning process, the sliding block 5 on the valve rod body 1 slides along the sliding groove 4 on the inner side of the O-ring 2, when the sliding block 5 slides to the end of the sliding groove 4, the sliding block 5 limits the turning work of the O-ring 2, the O-ring 2 is prevented from turning out of the embedded groove of the valve rod body 1, when the O-ring 2 needs to be replaced after the service life of the O-ring 2 is over, the O-ring 2 is firmly adhered to the embedded groove due to the aging and loosening of the O-ring 2 and the infiltration of moisture in the air, the worker is difficult to detach, the press rod 3 can press down, the press rod 3 drives the linkage block 7 to generate the acting force on one end of, the reset spring 6 is compressed to generate deformation, the transmission rod 8 ejects the O-shaped ring 2 out of the embedded groove in the sliding process, a worker can conveniently detach the O-shaped ring 2, after the pressing rod 3 is loosened, the reset spring 6 removes elastic force limitation, and the reset spring 6 with the L-shaped structure is driven to reset.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
