A check valve is a round valve used to open and close the parts, it can stop the backflow of media, and is used to produce the effect of its weight and media pressure. It belongs to the automatic valve category, also known as a check valve, check valve, backflow valve, or isolation valve. Valve movement is divided into lifting and swinging types. The lifting check valve and globe valve structure are similar, only they lack a driven valve stem. The medium flows in from the inlet side and out from the outlet side. A stainless steel check valve is often used as the bottom valve of the pumping device, which can stop the backflow of water. Stainless steel check valves are used in combination with globe valves to provide safe isolation.

How do check valves work?


Stainless steel check valveworks under the effect of fluid pressure in a single direction of operation, the valve flap opens, and the fluid runs in the opposite direction, because the fluid pressure and the self-weight of the valve flap together, affecting the valve seat, making the flow is broken. The stainless steel check valve is to use the flow of the medium itself to manipulate the valve flap of the switch, it can avoid the backflow of the medium. It allows the medium to flow in one direction only and stops the flow in the opposite direction. The valve flap opens when the fluid pressure flows in one direction, and when the fluid flows in the opposite direction, the flow is cut off because of the fluid pressure and the self-weight of the valve flap acting on the valve seat.

How to maintain the check valve daily?


The stainless steel check valve should be regularly inspected when placed for a long time. Every three months on the two channels, sealing surface dirt and rust, welding port protection condition, wiping the dirt and rust, and re-painting rust oil to protect. The check valve should be stored in a dry and ventilated indoor, moisture-proof, rain-proof, and rust-proof. The stainless steel check valve should be stored or transported in the closing device, the valve should be fixed in the open position, the inner mouth of the two ends of the passage with foam board blocking, and the port must be stuffed with a boring cover, to dust, rust, keep the channel clean and flat end, cylinder parts for appropriate packaging protection, shock, and anti-touch.
