What should I do if the valve leaks

When a valve leaks, corresponding measures should be taken according to the specific situation of the leak. Here are some common methods for handling valve leaks: 1、 Preliminary inspection and evaluation Determine the location of the leak: Carefully inspect the leakage point and determine where the leakage occurs in the valve, such as the flange connection, sealing surface, packing box, etc. Assess the degree of leakage: Observe the flow rate and speed of the leak, and evaluate the impact of the leak on the system

How to test the pressure of various industrial valves? The method is here!

Detailed explanation of pressure testing methods for various industrial valves The pressure testing of industrial valves is a crucial step in ensuring their performance and safety. Different types of valves require targeted pressure testing methods due to structural differences. The following provides a complete pressure testing operation guide based on general principles and specific valve types: 1、 General principle of pressure testing 1. Scope of application New valves usually only undergo sealing tests, but repaired or corroded valve bodies/covers require strength tests. The safety valve needs to undergo constant pressure and reseating pressure tests according to the instructions and specifications. 2. Inspection ratio

Design and structural characteristics of forged steel gate valve

The design and structural characteristics of forged steel gate valves are mainly reflected in the following aspects: Design Features 1. Application and medium adaptability: Forged steel gate valves are mainly used to cut off or connect media in pipelines, suitable for the working pressure range of Class 150~2500, as well as the working temperature range of -29~425 ℃ (carbon steel) or -29~500 ℃ (stainless steel). Different materials can be selected to adapt to various media such as water, steam, oil, acetic acid, oxidizing media, urea, etc. 2. Sealing performance: The sealing surface of forged steel gate valves is less susceptible to erosion and erosion by the medium, with good sealing performance and long service life.
