Discharge Valve

Discharge valve refers to a valve specifically used for the discharge of various pipeline equipment. Discharge valve is a valve device evolved from gate, mainly used on pipelines of water supply and drainage, building fire protection and other systems, or to discharge scale and sludge accumulated in boilers. When the boiler is full of water or shut down for cleaning, residual water is discharged. In addition, discharge valve is also suitable for regular discharge of high-pressure boilers. The drain valve uses a gear rotation of 90 degrees to drive the valve stem to lift and open and close, making it easy to operate and achieve rapid opening and closing. The sewage valve is mainly composed of components such as valve body, valve, spring, and operating rod. The discharge valve body produced by Shanghai Meiyan Yipump Valve is usually made of materials such as cast iron, ductile iron, cast steel, and stainless steel, and is coated with anti-corrosion paint to ensure its service life and anti-corrosion performance in harsh environments. The valve adopts a spherical or cylindrical design, and can be opened or closed by rotating or pulling the operating rod, thereby achieving the function of discharge or shut-off.
