Check Valve

Check valve: Check valve, also known as check valve or check valve, is used to prevent backflow of media in the pipeline. The bottom valve of the water pump suction is also a check valve.

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.

The check valve is divided into structures according to the structure, and can be divided into three types: a lift check valve, a swing check valve and a butterfly check valve. Lift check valves can be divided into vertical check valves and horizontal check valves. The swing check valve is divided into a single-valve check valve, a double-valve check valve and a multi-valve check valve. The butterfly check valve is a straight-through check valve. The above-mentioned check valves can be divided into three types: a threaded check valve, a flanged check valve and a welded check valve.

The installation of the check valve should pay attention to the following: 1. Do not allow the check valve to bear the weight in the pipeline. The large check valve should be independently supported so as not to be affected by the pressure generated by the piping system. 2. When installing, pay attention to the direction of the medium flow should be consistent with the direction of the arrow in the valve body. 3. The lifting vertical flap check valve should be installed on the vertical pipe. 4. The lift horizontal flap check valve should be installed on the horizontal pipe.

Nominal pressure or pressure rating of check valve: PN1.0-16.0MPa, ANSI CLASS 150-900, JIS10-20K Nominal diameter or caliber: DN15~900, NPS 1/4~36 Connection method: flange, butt welding, Thread, socket welding, etc. Applicable temperature: -196 ° C ~ 540 ° C Body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti. Different materials are used, and the check valves can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium and urea.
