Butterfly Valve Wafer Type PTFE Lined Cast Iron lever operated wafer type manual butterfly valve
The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical
channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between
0°-90°, which can play a role in flow adjustment. When the butterfly plate rotates to 90°, the valve reaches the maximum Opening.
The wafer butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover,
it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid
The characteristics of
1. Butterfly valve has the characteristics of simple structure, small volume, light weight, material consumption, small installation size, quick switch, 90° reciprocating rotation, small driving torque, etc., used to cut off, connect and adjust the medium in the pipeline, with good fluid control characteristics and close sealing performance.
2, butterfly valve can transport mud, at the mouth of the least liquid accumulation. Good sealing can be achieved under low pressure. Good regulation performance.
3, butterfly plate streamlined design, so that the loss of fluid resistance is small, can be described as an energy saving product.
4, the valve stem is through rod structure, after quenching and tempering treatment, has good comprehensive mechanical properties and corrosion resistance, abrasion resistance. Butterfly valve open and close the stem only for rotary movement without lifting operation, stem packing is not easy to damage, reliable sealing. It is fixed with the butterfly plate cone pin, and the overhanging end is designed to prevent the stem from collapsing when the connection between the stem and the butterfly plate breaks unexpectedly.
5, the connection mode is flange connection, clip connection, butt welding connection and lug clip connection.
The driving form is manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.
By operating temperature:
(1) high temperature. t> 450 °C butterfly valve.
(2) medium temperature butterfly valve. 120 C< t< 450 ℃ butterfly valve.
(3) normal temperature butterfly valve. A 40 c & lt; t< 120 °C butterfly valve.
(4) low temperature butterfly valve. A 100 & lt; t< A 40 °C butterfly valve.
(5) ultra-low temperature butterfly valve. t< 100 °C butterfly valve.
