Embodiment

[0023] A wear-resistant bushing 6 is provided on the inner hole wall of the valve body 7; a valve rubber extruding device 5 is arranged on the valve body 7, and the valve rubber 8 is arranged on the upper part of the valve rubber extruding device 5, and the valve rubber extruding device 5 passes through the valve body 7, inject the fluid medium into the valve rubber extruding device 5 through the upper injection hole, so as to extrude the valve rubber 8 from the upper end. At the same time, by controlling the injection amount of the fluid medium, the extrusion height of the valve rubber from the upper end can be controlled. When the valve cone 9 is in the non-working state, it is pressed on the valve rubber 8 by the spring 4. The outer part of the valve cone 9 is covered with a guide sleeve 3, which controls the trajectory of the valve cone 9 moving up and down. The inner side or the inner side and the outer side of the guide sleeve are arranged at the same time; the distance ...

Abstract

The invention relates to a valve rubber compensating type one-way valve, which is provided with a valve rubber extrusion device. When valve rubber is worn or damaged due to other reasons, a section of valve rubber is extruded by the valve rubber extrusion device according to the given amount, and the damaged part is compensated to ensure that the one-way valve normally works. Distance measuring devices are correspondingly arranged on a valve cone and a valve cover. Due to the distance measuring devices, the distance change of the valve cone relative to the valve cover can be observed at any time so as to reflect the wear condition of the valve rubber. The valve cone and the valve cover are prevented from colliding, the service life of the valve cone and a valve seat is effectively prolonged, and the frequency of closing down to replace spare parts is reduced.

Description

technical field [0001] The invention relates to a one-way valve, in particular to a valve rubber compensation type one-way valve, which uses the elastic deformation of the valve rubber to make up the gap between the valve cone and the valve seat to achieve the sealing effect. When the valve rubber is worn or damaged due to other reasons, the valve rubber extrusion device can be used to extrude a specified amount of valve rubber to compensate for the previous damaged part. Background technique [0002] For a long time, in the technical research and development of check valve products at home and abroad, the research and development of relevant technologies on how to improve the service life of the valve, reduce the frequency of shutdown maintenance, and reduce operating costs have attracted much attention from various countries. In recent years, the promotion and application of large-scale fluid conveying equipment based on diaphragm pumps, mortar pumps and mud pumps has deve...
