Silicon brass swing check valve，Silicon brass valve，Swing check valve

Product details

Check valve, also known as check valve or check valve, its role is to prevent the backflow of media in the pipeline. The bottom valve of the water pump suction close also belongs to the class of check valve.

The opening and closing parts are automatically opened or closed by the flow and force of the medium to prevent the backflow of the medium. The check valve belongs to the automatic valve class, which is mainly used on the pipeline with one-way flow of the medium, and only allows the medium to flow in one direction to prevent accidents.

According to the structure of the check valve, it can be divided into three kinds: lift check valve, swing check valve and butterfly check valve. Lift check valves can be divided into vertical and horizontal two types. Swing check valves are divided into single disc type, double disc type and multi-disc type. The butterfly check valve is straight-through, and the above check valves can be divided into three kinds of threaded connection, flange connection and welding in the connection form.

Brass swing check valves are widely used in many fields, mainly including the following aspects ‌ :

‌ tap water pipeline ‌ : in the tap water pipeline, brass swing check valve can effectively prevent the medium backflow, ensure the safety of water quality, prevent pollution ‌

‌ industrial pipeline ‌ : in metallurgy, chemical industry, construction, electric power and other industrial fields, brass swing check valve is widely used to prevent media backflow and protect equipment. Its excellent corrosion resistance enables it to operate stably in these environments ‌ for a long time

‌ fire control system ‌ : in the city fire control system, brass swing check valve plays a very important role. Its reliability and stability are essential for the normal operation of the fire fighting system, to prevent the reverse impact of water flow on the fire fighting work ‌

‌ air conditioning pipeline ‌ : in the air conditioning system, brass swing check valve can effectively prevent the media backflow, ensure the normal operation of the air conditioning system, avoid equipment performance decline ‌

‌ petroleum, chemical industry ‌ : brass swing check valve is suitable for petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other industries, suitable for all kinds of working conditions on the pipeline, applicable media including water, oil, steam, acidic media ‌

‌ Technical parameters and specifications ‌ : The technical parameters of brass swing check valve include nominal pressure (such as 1.6MPa), working medium (such as water), working temperature (-20℃ to 150℃), etc. The specifications (such as DN50 to DN150) can be selected according to the specific application scenario ‌

‌ Features ‌ : Brass swing check valve has the characteristics of simple structure, reliable operation, low fluid resistance and so on. It automatically opens and closes under fluid pressure without the need for an external power source, resulting in low operating costs ‌

In addition, the swing check valve is suitable for larger diameter, higher pressure and larger flow occasions, large flow capacity, fluid pressure in the fully opened state is almost unhindered, small pressure drop ‌
