What are the types of valve corrosion
1. The form of valve corrosion There are two forms of corrosion of metal valves, namely uniform corrosion and localized corrosion. The rate of uniform corrosion can be evaluated by the annual average corrosion rate. Metal materials, graphite, glass, ceramics and concrete, are divided into 4 gr...Read more -
Valve welding technology – how to weld high carbon steel
High carbon steel refers to carbon steel with w(C) higher than 0.6%, which has a greater tendency to harden than medium carbon steel and forms high carbon martensite, which is more sensitive to the formation of cold cracks. At the same time, the martensite structure formed in the welding heat af...Read more -
Valve degreasing method
01PART Cleaning Steps The components of the valve must undergo the following processes before assembly: 1. According to the processing requirements, some parts need to be polished, and the surface must not have processing burrs; 2. All parts are degreased; 3. After the degreasing is completed,...Read more -
How to Repair The Valve Static Sealing Surface
In the use of the valve, the sealing surface that does not produce relative motion and is always in a relatively static state is called a static seal, and the surface that acts as a seal is called a static sealing surface. On the valve, there are many structural forms of the static sealing surfac...Read more -
How to Judge Valve Appearance Defects
Structure and Dimensions 1. Appearance characteristics The main reasons are that the end of the valve stem is not processed, the valve stem and the handwheel cannot be closely combined, the valve opening and closing is not flexible, or the wall thickness of the valve body, the diameter of the va...Read more -
How to Deal With The Valve Is Not Closed Tightly
During the use of the valve, there are often some troubling problems, such as the valve is not closed tightly, and the valve is not closed tightly, what should I do?

Advantages and Disadvantages of Various Valves
1.Gate Valve A gate valve refers to a valve whose closing member (gate) moves along the vertical direction of the channel axis. It is mainly used to cut off the medium on the pipeline, that is, fully open or fully closed. In general, gate valves cannot be used to regulate flow. It can be applied...Read more -
Advantages and Disadvantages of Soft Sealing Gate Valve
Soft Seal Gate Valve Overview: Soft-sealed gate valve, also known as elastic seated gate valve, is a manual valve used to connect pipeline medium and switch in hydraulic engineering. The structure of soft sealing gate valve is composed of valve seat, bonnet, gate, gland, valve stem, handwheel, g...Read more
