Reasons and treatment procedures for internal leakage of ball valves

1、 Reasons for internal leakage of ball valves 1. Reasons for valve leakage during the construction period: ① Improper transportation and lifting can cause overall damage to the valve, resulting in internal leakage of the valve; ② When leaving the factory, the valve was not dried or treated with anti-corrosion measures after being pressurized, resulting in rusting of the sealing surface and internal leakage;

Analysis and Application of Gate Valves, Ball Valves, and Butterfly Valves

Gate valves, ball valves, and butterfly valves are the three essential commonly used valves on pressure vessels, each with unique functions. Gate valves, ball valves, and butterfly valves, as the three essential commonly used valves on pressure vessels, each play a unique role. But do you understand the specific differences and characteristics between them? Next, let's delve into the differences between these three types of valves together.

Classification and characteristics of pneumatic ball valves

Pneumatic ball valves are divided into O-type ball valves and V-type ball valves. The O-type ball valve adopts a floating structure, with a precision cast core and a hard chrome plated outer surface. The valve seat is made of reinforced polytetrafluoroethylene material, and the flow channel mouth is the same as the pipeline diameter, with extremely high flow capacity and minimal flow resistance. There is no leakage when closed, and it is generally used as a switch valve. It is particularly suitable for high viscosity, V-shaped ball valves with a fixed structure. The ball core has a V-shaped cut, which can shear media containing fibers and particles.

Common faults and troubleshooting methods of ball valves

Exclusion method: The assembly should be correct, the operation should be smooth, and it is not allowed to be used as a throttle valve; After the sphere is overturned, it should be repaired and the sealing seat should be replaced in a timely manner.

Analysis of gate valve types, installation precautions, and application areas

Gate valve, as an important fluid control device, has a gate valve as its opening and closing member, and the direction of the gate valve movement is perpendicular to the direction of the fluid. This design allows the gate valve to only be fully opened or fully closed, and cannot be adjusted or throttled. However, its characteristics of low fluid resistance, wide applicability, and unrestricted flow direction of the medium make it capable of performing well in many situations.

Characteristics, advantages and disadvantages of globe valves

Clamp type butterfly valves and flange type butterfly valves are two common types of butterfly valves. Both types of butterfly valves have a wide range of applications, but many friends cannot distinguish between clamp type butterfly valves and flange type butterfly valves and are not familiar with the differences between the two. The clamp and flange of butterfly valves are two connection methods. In terms of price, the clip on type is relatively cheaper ..
