Mud valve

Technical Field

The invention relates to the technical field of mud valves, in particular to a mud valve.

Background

The sludge discharge valve is an angle-shaped cut-off valve which is quickly opened and closed, and is generally arranged at the bottom of a tank body or a pool and used for discharging sludge and other sediments at the bottom of a container. Usually, the pneumatic mud valve is double-acting, that is, the upper part and the lower part of the cylinder piston are respectively provided with a channel of compressed air, and the on-off of an air source is controlled by an electromagnetic valve. The cylinder is installed on the valve body, and the valve clack is installed to the valve rod bottom, and the piston is then connected on upper portion, and each part pressure-bearing part sets up O type circle and is used for sealing, avoids muddy water or compressed air to leak.

The O-shaped ring is a quick-wear part, has limited service life, and can cause muddy water to leak after aging and abrasion. To the mud valve of cylinder direct mount on the valve body (being called the integral type), muddy water can leak to the cylinder in, the cylinder generally is the carbon steel material, corrodes easily, can lead to the piston bite after the inner wall is corroded, and the valve action is inflexible, has lost the function of mud valve fast switch. If the piston ring also damages simultaneously, muddy water then can continue to go upward, leaks to piston upper portion to carry by compressed air in to the switch board, lead to the fastener short circuit to burn out, other valves of this switch board control also can't move, influence production, therefore, we have proposed a mud valve and have solved above-mentioned problem.
