Hardware knowledge: basic knowledge of swing check valves

The swing check valve is also called a check valve or a check valve, and its function is to prevent the medium in the pipeline from flowing backward. The valve of the opening and closing member is opened or closed by the flow of the medium and the force to prevent the back flow of the medium from being called a check valve. Check valves are automatic valves, mainly used on pipes with one-way flow of media, allowing only the media to flow in one direction to prevent accidents.

First, the use of swing check valve:

Swing-type check valve is suitable for nominal pressure PN1.0MPa~42.0MPa, Class150-2500; nominal diameter DN15~1200mm, NPS1/2~48; working temperature -196~540°C for various pipelines, used to prevent The media is reversed. By using different materials, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea.

Second, the main materials of the swing check valve are:

Carbon steel, low temperature steel, duplex steel (F51/F53), titanium alloy, aluminum bronze, INCONEL625, SS304, SS304L, SS316, SS316L; chrome molybdenum steel, Monel (400/500), 20 #合金, Hastelloy and other metal materials.
