Types of stainless steel gate valves and their classification

Gate valve, also known as gate valve, is mainly composed of valve body, valve cover, gate plate, valve stem, valve seat and sealing packing. It is one of the common types of valves in isolation valves. The main purpose of the gate valve is to cut off the fluid. For this reason, it is often called the "cut-off" valve or "blocking" valve. There are many different structural forms of gate valves, and the structure types of sealing elements used are different.

What are the ways to connect the butterfly valve?

How is the butterfly valve connected? At present, the common butterfly valve on the market is flange connection, pairing connection, clamp connection, etc. 1. Flange connection The flange connection is a flange at both ends of the valve body, corresponding to the flange of the pipeline, which is installed on the pipe by bolting the flange.

The key difference between a high-quality valve body and a low-quality valve body determines the "fate" of industrial equipment!

In petroleum, chemical industry, electricity and other high-demand industrial scenarios, the quality of the valve body, as the core component of the fluid control system, not only determines the operating efficiency of the equipment, but also directly affects the safety, stability and long-term operating costs of the production system. A high-quality valve body means lower risk, longer service life and higher economic benefits.

High-pressure gate valve: a highly sealed fluid control solution under harsh working conditions

High-pressure gate valve is a valve specially designed for high-pressure conditions. Its structure and performance make it widely used in petroleum, chemical, electric power, metallurgy and other industrial fields. The following is a detailed analysis of its structural characteristics and advantages:

Six reasons for damage to the valve sealing surface

Because the seal plays the role of truncation and connection, adjustment and distribution, separation and mixing of the medium on the valve channel, the sealing surface is often corroded, eroded and worn by the medium, and is very easy to damage. There are two reasons for the damage of the sealing surface: man-made damage and natural damage. Man-made damage is caused by factors such as poor design, poor manufacturing, improper material selection, improper installation, poor use and poor maintenance.

Flange connection vs clip connection: how to choose the best pipe connection method?

Flange connection and clip-to-pin connection are common pipe connection methods. They have their own unique characteristics and applicable scenarios, and there are also some obvious differences. I. Characteristics of flange connection 1. Complex but stable structure: The flange connection is docked through two pipes or equipment with flange discs, and then the flange is fastened with bolts to form a whole. The structure is relatively complex, but the connection is more stable.
