Structural characteristics of butterfly valves

Butterfly valve is simple in structure, small size, light weight, material consumption of the province, the installation of small size, switch quickly, 90 ° reciprocating rotation, characterized by a small driving torque for the truncated, connected to regulate the pipeline in the medium, with Flow Control Characteristics of a good sealing performance and turn off.

Butterfly valve slurry can be transported in the pipeline at least I accumulated liquid. Low-voltage, you can achieve a good seal. Better regulation performance.

Butterfly plate streamline design, so the resistance loss of fluid can be described as an energy-saving products.

Stem to pass pole structure, after quenching and tempering treatment, there is a good comprehensive mechanical properties and corrosion resistance, anti-scratch. Butterfly valve gate valve stem only when the rotary movement without landing operation, the filler stem destruction is not easy, reliable sealing. Butterfly pin and plate-cone fixed outriggers to prevent the out-side design, in order to avoid stem junction with the butterfly plate when accidents stem collapse of fracture.

Connection there is flange connection on the folder connection, welded connections and Ear to the folder connection.

Drive the form of manual, worm gear drive, electric, pneumatic, hydraulic, electro-hydraulic linkage, such as implementing agencies, can realize remote control and automation.
