1. What is a side entry ball valve?

Side-entry ball valve, as a unique fluid control equipment, is widely used in petroleum, chemical industry, water treatment and other fields with its special structural design and excellent performance characteristics, duplex stainless steel check valve.

2. Structural characteristics of side-entry ball valves

Overall structure: Side-entry ball valve consists of valve body, ball, valve stem, sealing ring and other components. Among them, the valve body has a side inlet, so that the ball can be installed or removed from the side, which provides great convenience for maintenance and replacement. The ball is located in the center of the valve body and rotates to cut off or regulate the fluid.

Ball design: The ball of the side-entry ball valve usually adopts a spherical design and has a streamlined channel, which can reduce fluid resistance and improve the flow coefficient. The material of the sphere is usually stainless steel, carbon steel and other metal materials, which has good corrosion resistance and mechanical strength. In order to ensure the sealing performance of the sphere, the surface of the sphere is usually covered with a layer of elastic material, such as polytetrafluoroethylene (PTFE).

Sealing structure: The sealing structure of the side-entry ball valve includes the sealing between the ball and the valve seat and the sealing between the valve stem and the packing. Among them, the seal between the ball and the valve seat is the key. Elastic sealing rings or metal sealing structures are usually used to ensure reliable sealing under high pressure differences. The seal between the valve stem and the packing usually uses packing seal or O-ring seal, which can effectively prevent medium leakage.

3. Working principle and performance advantages of side-entry ball valve

Working principle: The working principle of the side-entry ball valve is to open, close and adjust the fluid channel by rotating the ball. When the ball rotates 90 degrees, the fluid channel is fully opened or closed; when the ball rotates to a certain angle, the fluid flow can be adjusted. By controlling the rotation angle of the sphere, precise control of fluid flow can be achieved. At the same time, the side-entry structure allows the ball to be installed or removed from the side, simplifying the maintenance and replacement operations, wafer type double check valve.

Performance advantages
(1) Small fluid resistance: Since the sphere channel is unobstructed, the fluid resistance is relatively small, which is beneficial to improving the flow coefficient.
(2) Good sealing performance: using elastic sealing ring and metal sealing structure to ensure reliable sealing under high pressure difference.
(3) Easy to operate: The fluid is controlled by rotating the sphere, and the operation is simple and fast. At the same time, the side-entry structure makes maintenance and replacement simple and convenient.
(4) Long service life: The use of wear-resistant materials and structural optimization design prolongs the service life of the valve. At the same time, ease of repair and replacement also reduces operating costs.
(5) Strong adaptability: Side-entry ball valves are suitable for a variety of fluid media and working conditions, including high temperature, high pressure, corrosive media, etc. Its unique structural design allows it to maintain good performance in harsh environments.

4. Discussion on the application fields of side-entry ball valves

Petrochemical industry: In the petrochemical industry, side-entry ball valves are widely used in various fluid pipeline systems, such as the transportation and storage systems of crude oil, natural gas, refined oil and other media. Its excellent sealing performance and low fluid resistance can ensure the safe and stable operation of the system. At the same time, its adaptability also enables it to maintain good performance under harsh working conditions, forged steel swing check valve.

Water treatment: In the water treatment industry, side-entry ball valves are favored for their good corrosion resistance and easy maintenance and replacement. Whether it is a water supply system, drainage system or sewage treatment system, side-entry ball valves can provide reliable fluid control solutions. In addition, its long service life and easy maintenance also reduce the operating costs of the water treatment system.

Electric power: The electric power industry has high requirements on the safety and reliability of valves. Side-entry ball valves have received widespread attention for their excellent sealing performance and low fluid resistance. Its high temperature resistance and high pressure resistance make it suitable for the fluid control system of various power generation equipment, such as nuclear power plants, thermal power plants, etc. In addition, its convenient repair and replacement features also improve the valve's efficiency and maintenance convenience.

Pharmaceuticals and Food: In the pharmaceutical and food industries, the hygiene requirements for valves are very strict. Side-entry ball valves are made of non-toxic and harmless materials such as stainless steel and comply with relevant health standards. At the same time, its simple structure and easy cleaning also facilitate cleaning and disinfection operations during the production process. In addition, the side-entry structure allows the ball to be installed or removed from the side, simplifying the maintenance and replacement operations and reducing the risk of production interruption.

Papermaking and Textile: In the papermaking and textile industries, the performance of fluid control equipment has an important impact on production efficiency and product quality. Side-entry ball valves are widely used in these industries due to their excellent sealing performance, low fluid resistance and convenient maintenance and replacement. Whether in slurry conveying systems, dyeing equipment or wastewater treatment systems, side-entry ball valves provide reliable fluid control solutions. At the same time, its adaptability also enables it to maintain good performance under different working conditions, full opening check valve.
