&D handle wafer type soft seal butterfly valve introduction: The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve opening, closing or adjustment. The valve is called a butterfly valve. The Toyama butterfly valve is usually less than fully open to fully closed. The butterfly valve and butterfly rod themselves do not have self-locking force. In order to position the butterfly plate, a worm gear reducer must be installed on the valve rod. The use of worm gear reducer not only makes the butterfly plate self-locking, allowing the butterfly plate to stop at any position, but also improves the operating performance of the valve.
The characteristics of Toyama butterfly valves for industrial use are that they can withstand high temperatures and have a high applicable pressure range. Toyama valves have a large nominal diameter, the valve body is made of carbon steel, and the sealing ring of the valve plate uses a metal ring instead of a rubber ring. Large high-temperature butterfly valves are manufactured by welding steel plates and are mainly used in flue ducts and gas pipelines for high-temperature media.
The advantages of the D-handle wafer type soft seal butterfly valve are as follows
It is convenient and quick to open and close, labor-saving, has small fluid resistance, and can be operated frequently.
, simple structure, small size and light weight.
, can transport mud with minimal liquid accumulation at the pipe mouth.
Under low pressure, good sealing can be achieved.
, good adjustment performance.
