Problems solved by technology

[0003] In the prior art, there is no valve using two-way grinding discs. Therefore, when the fluid passes through the valve, it is easy to form accumulation in the valve, causing coking and scaling of the medium in the inner cavity of the valve, leading to problems such as valve failure or jamming.

Abstract

The invention relates to a bi-direction grinding sheet multihole valve which comprises a left valve body (1), a right valve body (2), a fixed grinding sheet (3) and a rotating grinding sheet (4). The left valve body (2) is arranged on the right valve body (1). The fixed grinding sheet (3) is arranged between the right valve body (1) and the left valve body (2). The rotating grinding sheet (4) is arranged on the fixed grinding sheet (3). The multihole valve further comprises a locating shaft (5) and a spring (26). The spring (26) is arranged in the rotating grinding sheet (4). The locating shaft (5) is arranged between the spring (26), the rotating grinding sheet (4) and the fixed grinding sheet (3). The mutihole valve further comprises a valve rod (10), a pin (8) and a rotating arm (7). The valve rod (10) is connected with the rotating arm (7) through the pin (8). The rotating arm (7) is connected to the rotating grinding sheet (4). The bi-direction grinding sheet multihole valve is best in sealing performance of plane contact due to the adoption of plane sealing face contact. Moreover, the bi-direction grinding sheet multihole valve rotates around the axis so as to be prolonged in service life.

Description

technical field [0001] The invention relates to an industrial valve, in particular to a two-way grinding disc porous valve. [0002] Background technique [0003] There is no valve using two-way grinding discs in the prior art, so when the fluid passes through the valve, it is easy to form accumulation in the valve, causing the medium to coke in the inner cavity of the valve, fouling, which leads to problems such as failure of the valve switch or stuck. . [0004] SUMMARY OF THE INVENTION [0005] The purpose of the present invention is to provide a two-way grinding disc porous valve. [0006] The technical scheme of the present invention is as follows: a two-way grinding disc porous valve, comprising a left valve body (1), a right valve body (2), a positioning sheet (3) and a rotating grinding sheet (4), and the left valve body (2) is installed On the right valve body (1), the fixed grinding plate (3) is installed between the right valve body (1) and the left valve bo...
