Problems solved by technology

[0005] The invention provides an oil film sealing structure of a valve, one of which is to have the function of increasing the solidity, so as to solve the problem that when the oil film sealing structure of the valve is in use, due to its poor fixity, the oil film is easily caused by the impact of the water flow. The connection of the oil film seal structure is loose, which affects the tightness of the structure; another purpose is to solve the difficulty in the installation and disassembly of the oil film seal structure of the valve, which leads to slow maintenance and replacement of the oil film seal structure in the later stage, affecting the oil film seal The problem of convenient use of the structure, in order to achieve the effect of convenient disassembly and installation

Abstract

The invention discloses an oil film sealing structure of a valve, and relates to the technical field of sealing structures, the oil film sealing structure comprises a valve main body, a connecting base, a sealing flange and a connecting pipe, the bottom of the valve main body is fixedly provided with the connecting base, the middle of the valve main body is provided with the sealing flange, and one side of the bottom of the sealing flange is fixedly connected with the connecting pipe. Through movement of the sleeving block towards the two sides, the sleeving block drives the sleeving clamping block to be separated from the limiting groove, the clamping separation effect is achieved, accordingly, the upper clamping plate and the lower clamping plate are conveniently and vertically separated, the limiting block is conveniently disassembled, then the telescopic rod telescopically moves to push the clamping block to eject out of the inner wall, separated from the sealing film, of the valve main body, and the sealing film is separated from the valve main body. And the problem that the oil film sealing structure of the valve is difficult to mount and dismount, so that the later maintenance and replacement of the oil film sealing structure are slow is solved, the device is convenient to dismount, the convenience of the device is improved, and the later maintenance of the device is facilitated.

Description

technical field [0001] The invention relates to the technical field of sealing structures, in particular to an oil film sealing structure of a valve. Background technique [0002] The valve is a control component in the fluid conveying system, with functions such as cut-off, regulation, diversion, diversion, and pressure relief.
