Purpose: Energy saving side opening flap door is an important equipment to ensure the safe operation of pump stations. Its function in pump stations is to cut off flow and prevent water backflow during shutdown. It is mainly used for flood control and drainage, farmland irrigation, urban water supply and drainage, cross basin water transfer, as well as water supply and distribution for various large-scale enterprises.
Main technical features:
1. No need for any opening or closing device, it can automatically open and close. The most significant feature of energy-saving side opening door compared to suspended door is:
The valve body hinge shaft is vertically arranged and an optimal tilt angle is designed, utilizing the force of the door's weight to close the door. No opening or closing device is required for doors with large, medium, or small diameters.
2. Safe and stable, energy-efficient and efficient. The energy-saving side opening flap door has low resistance during operation, a large opening angle, and low impact force when closing, eliminating water hammer and vortex generated when water flows out; No need for manual, electrical, pneumatic, or hydraulic control, no manual operation, saving a lot of manpower and material resources, improving the reliability and efficiency of pump station operation, reducing operation and maintenance costs, and lowering pump station energy consumption. In actual operation, according to the testing center of the Ministry of Water Resources, the energy-saving side opening door saves 22.5% of electricity compared to the suspended door.
3. Easy maintenance and long service life. The valve shaft of the flap door is made of stainless steel material, and the shaft pin seat is a copper alloy graphite lubricated bearing, which will not rust and has reliable sealing. The door seat is made of carbon steel material; The product structure is simple and reasonable, with a unique operating trajectory, a service life of over 30 years, and easy maintenance.
