Overview

As a key industrial component, walking valve cover is widely used in various fluid control systems. With the continuous progress of industrial technology, the performance requirements of the walking valve cover are getting higher and higher.

Working principle

The walking valve cover is an important part of the fluid control system, which mainly realizes the on-off control of the fluid by opening and closing the valve. When the valve is opened, the valve cover is separated from the valve seat, and the fluid flows through the valve channel; when the valve is closed, the valve cover is tightly attached to the valve seat to prevent fluid flow. The movement of the valve cover is usually driven by an actuator, such as a pneumatic, electric or hydraulic actuator.

Manufacturing process

The manufacturing process of the walking valve cover mainly includes material selection, casting, processing and testing.

1. Material selection: The choice of valve cover material directly affects its performance and service life. Commonly used materials include cast iron, carbon steel, stainless steel, etc. For special environments, special materials with corrosion resistance, high temperature resistance and wear resistance are also required.

2. Casting: The casting process of the valve cover requires strict control of raw materials, temperature, pressure and other parameters to ensure the quality of the castings.

3. Processing: Bonnet processing includes turning, milling, drilling and other processes to obtain accurate size and shape.

4. Testing: After the manufacturing is completed, the valve cover needs to be strictly tested, including pressure testing, leak testing, etc., to ensure that its performance meets the requirements.

Application Areas

Walking valve cover is widely used in petroleum, chemical industry, electric power, metallurgy, water treatment and other fields. Specific application scenarios are as follows:

1. Oil field: used for fluid control in oil well drilling, oil and gas transportation, etc.

2. Chemical industry: used for fluid control in chemical reactors, pipelines, etc.

3. Electric power field: fluid control system for boilers, generator sets and other equipment.

4. Metallurgical field: used for fluid control in steel smelting process, such as oxygen, nitrogen and other gases control.

5. Water treatment field: used for fluid control of water treatment equipment, such as water supply and drainage, sewage treatment, etc.
