Mud drainage valve

Abstract

The invention relates to the technical field of mud drainage valves, and discloses a mud drainage valve. The mud drainage valve comprises a valve body, a gas cylinder bracket and a gas cylinder, wherein a water inlet is formed in one side of the valve body; a water outlet is formed in the bottom of the valve body; a valve cover is mounted at the top end of the valve body; the gas cylinder bracketis fixedly arranged on the valve cover; the top end of the gas cylinder bracket is equipped with the gas cylinder; the piston is arranged inside the gas cylinder; a tapered spring is arranged at the top end of the piston; the bottom end of the piston is equipped with a valve rod; the valve rod is inserted into the gas cylinder bracket; the valve rod penetrates through the valve cover; and the endof the valve rod is fixedly equipped with a valve clack. The gas cylinder bracket is arranged between the gas cylinder and the valve rod for isolating the two, so that mud water is leaked outside after an O-shaped ring at the valve rod is damaged, and the mud water does not leak into the gas cylinder to cause follow-up faults.

Description

technical field [0001] The invention relates to the technical field of mud discharge valves, in particular to a mud discharge valve. Background technique [0002] The sludge discharge valve is a fast-switching angle-shaped cut-off valve, which is generally installed at the bottom of the tank or pool to remove sludge and other sediments at the bottom of the container. Usually, the pneumatic mud discharge valve is double-acting, that is, the upper and lower parts of the cylinder piston are respectively connected to one channel of compressed air, and the air source is controlled by a solenoid valve. The cylinder is installed on the valve body, the disc is installed at the bottom of the valve stem, and the upper part is connected to the piston. The pressure-bearing part of each component is equipped with an O-ring for sealing to avoid leakage of muddy water or compressed air. [0003] The O-ring is a vulnerable part with a limited service life, and it will cause muddy water to ...

AI Technical Summary

Problems solved by technology

[0003] The O-ring is a vulnerable part with a limited service life. After aging and wear, it will cause muddy water to leak out

For the mud discharge valve (called integrated type) whose cylinder is directly installed on the valve body, muddy water will leak into the cylinder. The cylinder is generally made of carbon steel, which is easy to corrode. Corrosion of the inner wall will cause the piston to jam and the valve action is not flexible. , lost the quick switch function of the mud discharge valve

If the piston ring is also damaged at the same time, the muddy water will continue to go up, leak to the upper part of the piston, and be carried to the control cabinet by the compressed air, causing the clamp to be short-circuited and burned, and other valves controlled by the control cabinet will also be unable to operate, affecting production. , we propose a mud valve to solve the above problems
