Application instructions of vacuum ball valve in vacuum system

Vacuum ball valve is a commonly used vacuum valve, widely used in industrial fields.The application, principles, standards, characteristics, types, models, specifications and instructions of vacuum ball valves will be introduced in detail below.

一. Application

Vacuum ball valves are mainly used to control the switching of fluids and are suitable for various media, including gas, liquid and steam.It can work in high vacuum environment, so it is widely used in vacuum systems, chemical industry, petroleum, metallurgy, electric power, pharmaceutical, food and other industries.

二. Principle

The principle of vacuum ball valve is to control the on-off of fluid by rotating the ball.When the ball contacts the valve seat, the valve closes; when the ball rotates to separate from the valve seat, the valve opens.The rotation of the sphere is achieved by manual operation or electromechanical drive.

三. Characteristics

1. Simple structure, small size, light weight, easy to install and maintain.

2. The sealing performance is good, and the fluid can be completely cut off when the valve is closed to prevent leakage.

3. It has small fluid resistance and large flow capacity, and can meet high flow requirements.

4.It has strong corrosion resistance and is suitable for various media.

5.The switch is flexible and easy to operate, and can be controlled manually or automatically.

四、type

Vacuum ball valves can be divided into KF vacuum ball valves, loop flange vacuum ball valves, vacuum two-piece ball valves, vacuum three-piece ball valves, vacuum two-way ball valves, vacuum three-way ball valves, etc. according to the structural form. According to the material, they can be divided into stainless steel 304 Vacuum ball valve, stainless steel 316 vacuum ball valve.

五、model

Vacuum ball valve models are named according to their structure, material, connection method, etc.Common models include GU、GUQ、GUD、GU-A、GUQ-A、GUD-A,and so on

六、Specification

The specifications of vacuum ball valves include diameter, pressure and other parameters.Common calibers include DN10、DN16、DN20、DN25、DN50、DN100、DN150、DN200、DN250、DN300,and so on.Users can choose appropriate specifications according to actual needs.

To sum up, the vacuum ball valve is a widely used valve with the characteristics of simple structure, good sealing and low fluid resistance.According to different application requirements, vacuum ball valves of different types, models and specifications can be selected.Before use, users should read the instructions in detail to understand the product’s technical parameters and usage methods to ensure the normal operation of the valve.
