Uncover the charm of the ball valve: an indispensable industrial pipeline control magic weapon

As a common type of valve in industrial piping systems, ball valves have won a wide range of applications due to their unique structure and excellent performance. This article will take you to understand the principle, characteristics and application areas of the ball valve, so that you have a deeper understanding of this product.

1. ball valve overview

Ball valve, as the name suggests, is a kind of valve with a sphere as the opening and closing parts. It realizes the opening and closing of pipeline by rotating 90 degrees. Ball valves have the advantages of simple structure, good sealing performance, low fluid resistance, long service life, etc. They are widely used in petroleum, chemical, electric power, metallurgy, urban construction and other fields.

2. Classification and characteristics of ball valves

▌ Classification by structure

(1) Floating ball ball valve: the ball is not fixed, relying on media pressure and sealing seat to realize the seal. Applicable to low-pressure occasions.

(2) fixed ball ball valve: the ball is fixed in the middle of the valve, the sealing seat can be moved. Applicable to high-pressure occasions.

(3) elastic ball valve: the ball and the sealing seat between the use of elastic materials, has a better sealing performance. Applicable to high-pressure occasions.

▌ Classification by Driving Mode

(1) manual ball valve: through the handle rotation to realize the switch.

(2) Electric ball valves: switching is realized through motor drive.

(3) Pneumatic ball valves: compressed air drive to realize the switch.

(4) pneumatic ball valve: through the liquid drive to realize the switch.

3、Advantages and application areas of ball valves

▌ Advantages

(1) simple structure: ball valve structure is compact, light weight, easy to install.

(2) Good sealing performance: the ball valve adopts the ball and sealing seat sealing, large sealing area, excellent sealing performance.

(3) small fluid resistance: ball valve channel is linear, small fluid resistance, energy saving and consumption reduction.

(4) Long service life: the ball valve is made of wear-resistant materials, long service life.

▌ Application Fields

(1) Petroleum, chemical industry: used for pipeline system cut off, regulation and pressure reduction.

(2) Electric power: used for boiler feed water, steam piping cut off and regulation.

(3) Metallurgy: used for cutting off and regulating the pipeline of blast furnace gas and oxygen.

(4) urban construction: for water supply, drainage, heating pipeline cut off and regulation.

4、Purchase of ball valves considerations

Choose the right type of ball valve according to the actual working conditions.

● Pay attention to the material of the ball valve to ensure that it meets the requirements of the medium and working temperature.

● Understand the sealing performance of the ball valve to ensure safety and reliability.

● Select ball valves produced by regular manufacturers to ensure product quality.

Summarize: ball valve as an important part of the industrial piping system, its excellent performance and wide range of applications make it an indispensable control equipment. Understanding the principle, characteristics and application of ball valves helps us to better choose and use this product, contributing to China's industrial development.
