Product Description

Anti coking ball valve is a Special Valve used under high temperature and high pressure conditions. It adopts a special anti-static design to ensure that the ball valve will not experience electrostatic discharge during use, preventing the coking phenomenon of the ball valve, and thus protecting the normal operation of the valve and pipeline. The following will introduce the anti coking ball valve from the aspects of principle, design, advantages and disadvantages.

1、 Principle of anti coking ball valve

Petroleum, chemical, metallurgical and other industries often produce and process under harsh conditions such as high temperature, high pressure, and high sulfur content, which poses great challenges to equipment such as ball valves. The anti coking ball valve is designed to solve these problems. It is mainly used to control the flow of fluids under high temperature and high pressure conditions, and is an instrument for controlling fluid through spherical rotation. Compared to ordinary ball valves, it not only has stronger functions but also higher safety performance. Its anti-static principle is to use a specially designed anti-static device to directly contact the metal parts of the ball valve with the ground, thereby eliminating the danger of electrostatic discharge.

2、 Design of anti coking ball valve

Valve body design: The valve body and valve cover adopt a special structural design, which can expand their contact surface and strengthen leakage protection.

Sealing structure design: The anti coking ball valve adopts an elastic sealing structure, which can withstand large pressure and achieve good sealing effect.

Reinforced Valve Stem: The valve stem inside the ball valve also has a special design, which is not easy to wear when subjected to high temperature and pressure.

Anti static design: The anti coking ball valve is equipped with conductive parts between the valve parts stem and the frame to provide conductivity. During the process of valve opening and closing, the static electricity generated when manually touching the switch can be eliminated through the contact between the valve stem accessories and the frame. At the same time, it can also reduce the charge inside the pipeline and prevent electrostatic discharge from causing explosions.

Reasonable ball material: The ball material should be made of heat-resistant, corrosion-resistant, and wear-resistant materials, such as fluoroplastics, titanium alloys, Hastelloy, etc.

Advantages Of Anti Coking Ball Valve

3、 Advantages and disadvantages of anti coking ball valve

advantage:

(1) Prevent ball valves from coking due to electrostatic discharge during use.

(2) It has good sealing effect and can withstand large pressure.

(3) Reasonable design and long service life.

(4) Made of high-quality materials, it is corrosion-resistant, wear-resistant, and high-temperature resistant.

Disadvantages:

(1) The manufacturing cost of anti coking ball valves is higher than that of general ball valves.

(2) The structure of the anti coking ball valve is complex and requires professional technical personnel for maintenance.

(3) The usage requirements are high, and without professional technical personnel for maintenance and operation, malfunctions are prone to occur.
