Square stem soft-seated butterfly valve manufacturers will take you to understand: the advantages and disadvantages of butterfly valves and installation and maintenance
Square stem soft-seated butterfly valve manufacturers tell you that 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. The square stem soft-seated butterfly valve manufacturer tells you that the butterfly valve is usually less than 90 degrees from fully open to fully closed. The butterfly stem itself has no self-locking ability. For the positioning of the butterfly plate, a worm gear reducer should be installed on the valve stem. The use of a worm gear reducer can not only make the butterfly plate self-locking and stop at any position, but also improve the operating performance of the valve.
The manufacturer of Square stem soft-seated butterfly valve tells you that the special butterfly valve for industry has the characteristics of high temperature resistance and high applicable pressure range. The valve has a large nominal diameter. The valve body is made of carbon steel. The sealing ring of the valve plate uses a metal ring instead of a rubber ring. The large high temperature butterfly valve is made of steel plate welding, and is mainly used for flue ducts and gas pipes of high temperature media.
1. It is convenient and quick to open and close, labor-saving, low fluid resistance, and can be operated frequently.
2. The square stem soft-seated butterfly valve manufacturer tells you that the structure is simple, small in size and light in weight.
3. Mud can be transported, with less liquid accumulated at the pipe mouth.
4. Under low pressure, good sealing can be achieved.
5. The manufacturer of Square stem soft-seated butterfly valve tells you that the adjustment performance is good.
1. The working pressure and working temperature range are small.
2. Poor airtightness.
Installation and maintenance:
1. During installation, the valve disc should be stopped in the closed position.
2. The opening position should be determined according to the rotation angle of the butterfly plate.
3. The manufacturer of Square stem soft-seated butterfly valve tells you that the butterfly valve with bypass valve should be opened before opening.
4. The square stem soft-seated butterfly valve manufacturer tells you that it should be installed according to the manufacturer's installation instructions. The heavy-weight butterfly valve should be set up with a firm foundation.
