The butterfly valve is a valve that uses a disc type opening and closing member to reciprocate about 90° to open, close or adjust the flow of the medium. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate and fast, and also has good flow regulating function and closed sealing characteristics. It has been developed in the past ten years. One of the fastest valve varieties. Butterfly valves are used in a wide range of applications. The variety and quantity used are still expanding, and the development of high temperature, high pressure, large diameter, high sealing, long life, excellent regulation characteristics, and one valve multifunction. Its reliability and other performance indicators have reached a high level.


Characteristics

1. The streamlined design of the butterfly board, so that the fluid resistance loss is small, can be described as an energy-saving product.

2. The valve stem is a through-rod structure. After quenching and tempering treatment, it has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is opened and closed, the valve stem only rotates and does not move up and down. The packing of the valve stem is not easy to be broken and the sealing is reliable. It is fixed with the cone pin of the butterfly plate, and the overhanging end is designed to prevent the punch-out type, so as to prevent the valve stem from collapsing when the valve stem and the butterfly plate are accidentally broken.

3. Connection methods include flange connection, clamp connection, butt weld connection and lug-to-clip connection.

The driving form includes manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation.


Disadvantage

1. The use pressure and working temperature range are small.

2. Poor sealing.

The butterfly valve can be divided into a bias plate type, a vertical plate type, a slant plate type and a lever type according to the structure.

Available in sealed form, both soft and hard. The soft seal type is generally sealed with a rubber ring, and the hard seal type is usually sealed with a metal ring.

According to the connection type, it can be divided into flange connection and clip type connection; according to the transmission mode, it can be divided into manual, gear transmission, pneumatic, hydraulic and electric.
