Flow limiting valve with cleaning function for industrial water room

Abstract

The invention provides a flow limiting valve with a cleaning function for an industrial water room. The flow limiting valve comprises a valve body; a sealing device and a flow limiting mechanism are installed in the valve body, and the flow limiting mechanism is located on the left side of the sealing device; an adjusting device is mounted at the top of the valve body, a pushing part is mounted in the adjusting device, and a limiting part is mounted at the top of the adjusting device; and the cleaning device is installed on the right side of the valve body, a collecting device is installed at the bottom of the cleaning device, and a driving mechanism is installed in the cleaning device. A sealing block is fixedly connected with the valve body, and two sealing rings are fixedly installed in the sealing block, so that the sealing effect between the sealing block and a moving block is improved; and a spring is fixedly installed between a limiting disc and the moving block, so that the moving block moves rightwards under the action of the spring when the valve is closed, the section of the moving block is of a trapezoidal structure, and the sealing block and the moving block are tightly attached under the action of the spring and water flow pressure.

Description

technical field [0001] The invention belongs to the technical field of valves, and more specifically relates to a flow limiting valve for an industrial water room with its own cleaning function. Background technique [0002] Valves are the control components in the fluid conveying system, with the functions of cut-off, adjustment, diversion, prevention of reverse flow, pressure stabilization, diversion or overflow pressure relief; valves can be used to control air, water, steam, various corrosive media, mud , oil, liquid metal and radioactive media and other types of fluid flow. [0003] For example, in the patent with application number CN201210199191.X, a flow limiting shut-off valve is disclosed, including a flow shut-off valve and a shut-off valve; the flow shut-off valve includes a valve body, a piston and a biasing component; There is a through cavity, and the water outlet of the through cavity is provided with a sealing seat; the piston can be axially reciprocated an...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a flow limiting valve for industrial water room with self-cleaning function to solve the problem that the water flow is cut off by the gate plate when it is closed, and the gate plate wears seriously when it is used for a long time. The sealing effect is reduced, it is not easy to use, and because of the high pressure of the water flow in the industrial water room, when the pipe or faucet is suddenly damaged, it will take a certain time for the staff to close it, and it cannot be closed quickly. The residue and rust in the water cannot be cleaned during use, which affects the water quality.
