Anti-blocking mud pump valve

Abstract

The invention discloses an anti-blocking mud pump valve. The anti-blocking mud pump valve comprises a valve body in an inverted T-type, and an adjustment cavity is formed in the vertical portion of the valve body. A circulation cavity which communicates with the adjustment cavity is formed in the horizontal portion of the valve body. A valve cover is disposed at the top of the vertical portion ofthe valve body, and a valve stem penetrating the valve cover is disposed in the vertical portion of the valve body. An adjustment block is disposed at one end in the vertical portion of the valve stem, and a cleaning hole is formed in the inner wall, located below the vertical portion, of the circulation cavity, A cone-shaped cleaning head for crushing mud is disposed in the cleaning hole, and a movable groove is formed in the side wall of the circulation cavity. A rack is disposed in the movable groove, and one end of the rack is connected with a baffle for blocking the cleaning hole. Saw blades of the rack are disposed downwards, and the saw blades mesh with a gear of the end portion of a second motor drive shaft. The purposes that hardened mud is broken, the valve body is prevented fromblockage, the circulation space of the circulation cavity is ensured, and the normal use of the mud pump valve is ensured are achieved.

Description

technical field [0001] The invention relates to the field of valve production and application, in particular to an anti-clogging mud valve. Background technique [0002] A valve is a mechanical device that controls the flow, flow direction, pressure and temperature of a fluid medium in circulation. A valve is a basic component in a piping system. [0003] In the prior art, the mud valve is a commonly used and necessary pipeline control device, which is used to control the circulation system of mud circulation and closure. During the mud circulation process, the flow chamber will not be blocked. When the mud flow stops , because the mud is pasty, some material mud will adhere to the bottom side wall of the flow chamber, and the residual mud will dry and harden, reducing the flow space of the flow chamber, and even causing damage to the connection between the flow chamber and the adjustment chamber. Blockage affects the normal use of the mud valve. Contents of the invention...
