The structure and application fields of the lug type butterfly valve
Product Introduction of lug type butterfly valve: The driving mode of the lug butterfly valve can be manual, worm gear, pneumatic, electric, hydraulic. The connection method can choose flange and wafer, the structure can choose single eccentric, center line, double eccentric, triple eccentric, and the sealing structure can choose soft seal or hard seal. The […]
Uses and characteristics of manual butterfly valve (4)
Installation and maintenance of manual butterfly valve: During installation, the disc should stop in the closed position. The opening position should be determined according to the rotation angle of the butterfly plate. For the butterfly valve with bypass valve, the bypass valve should be opened before opening, and the installation should be carried out according […]
Uses and characteristics of manual butterfly valve (3)
Features of manual butterfly valve: The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve opening and closing or adjustment of the valve is called a butterfly valve. The butterfly valve is usually less than 900 from fully open to fully […]
Uses and characteristics of manual butterfly valve (2)
Uses/application of manual butterfly valve: Used in the gas pipeline in the sulfuric acid industry: the inlet and outlet of the blower in front of the furnace, the inlet and outlet of the relay fan, the electric demisting series and the connecting valve, the inlet and outlet of the S02 main blower, the adjustment of […]
Uses and characteristics of manual butterfly valve (1)
The butterfly plate of the manual butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0°-90°. When the rotation reaches 90°, the valve is fully opened. The butterfly valve is […]
Installation instructions of the wafer type butterfly valve
Preparation before installation of wafer type butterfly valve: 1. Check whether the specifications and materials of the butterfly valve conform to the design before installation. 2.
