Abstract

The invention discloses a control valve of a hydraulic flat-type slurry pump, comprising a valve body, a valve rod (7) and parallel flashboards (11), wherein the valve body is provided with an upper chamber and a lower chamber for containing the parallel flashboards. The control valve is characterized in that the valve body comprises a left valve body (10), a middle valve body (9) and a right valve body (12) which are in butt joint connection; valve seat sealing rings (14) are arranged between the left valve body (10) and the middle valve body (9) and between the middle valve (9) and the right valve body (12); and the upper chamber, the lower chamber, the parallel valve flashboards (11) and the valve rod (7) are all arranged at the middle valve body (9). The control valve of the hydraulic flat-type slurry pump disclosed by the invention has flashboards which can be closed in place and are good in sealing effect and long in service life.

Description

technical field [0001] The invention relates to a valve, in particular to a hydraulic plate type slurry pump control valve. Background technique [0002] The existing hydraulic ram-type slurry pump control valve (ZL200720063700.0) has the following defects: first, the groove at the bottom of the valve body is prone to slag accumulation, causing the ram to fail to close in place; second, the sealing surface cannot be replaced after wear; The main reason is that the passage of the valve body is easy to wear and has a short service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hydraulic plate type slurry pump control valve with good sealing effect and long service life. [0004] In order to solve the above-mentioned technical problems, the control valve of the hydraulic plate type slurry pump provided by the present invention includes a valve body, a valve stem and a parallel gate, and the valve body is p...
