What is the difference between the check valve rcvx and SFCV?
3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.
One way check valve is check valve, only for preventing all kinds of pipelines or equipment on the flow medium reverse flow one-way valve.Check valves are widely used and there are many kinds of check valves. The following are common water supply and heat check valves:1, spring: the liquid from the bottom up, rely on the pressure spring controlled valve, the pressure disappears, the spring force the valve, sealing liquid backflow. Often used in the smaller diameter check valve.2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.
SFCV rubber check valve parts design mainly by the body, valve cover and rubber valve composed of three major parts. Its main features are: rubber valve in the valve by the steel plate, steel bar and reinforced nylon cloth as the substrate, the outer rubber covered, the valve switch life of up to 1 million times. H44X (SFCV) series rubber check valves adopt full flow area design. They have the characteristics of small head loss, easy accumulation of debris, easy maintenance and so on. H44X (SFCV) series rubber check valve is mainly suitable for horizontal installation of water supply and drainage system. It can be installed at the water outlet of the pump to prevent backflow and water hammer damaging the pump. H44X (SFCV) series rubber check valves can also be installed on the bypass pipe of the reservoir inlet and outlet to prevent backflow of water to the water supply system. Check valves are generally applicable to clean media and are not suitable for media containing solids and viscosity.Analysis of the main characteristics of RCVX rubber valve check valve: the valve body, valve cover, valve and spring, mainly used for pipeline industry departments of water supply and drainage system, oil and chemical exports, to prevent the media counter. Due to the design of the sealing ring of the product, the closing time is short, and the water hammer pressure can be reduced. The valve is made of nitrile rubber and steel plate by high temperature. It is resistant to erosion and has good sealing performance. The product structure is simple, and the maintenance, maintenance and transportation are very convenient.
