D381X grooved worm wheel butterfly valve
D381X grooved worm wheel butterfly valve has the advantages of fast installation, simplicity, reliability, no limitation of installation site, easy maintenance of pipelines and valves, vibration isolation, sound insulation and angle range, overcoming the analog difference caused by the connection of pipelines with different axes, and solving the thermal expansion and cold contraction caused by temperature difference. Turbine groove butterfly valve can be widely used in water supply and drainage, fire protection, petroleum, chemical industry, medicine, steel and other pipelines as truncation or regulation. The grooved butterfly valve is designed with advanced technology from abroad and many times improved by our company.
Characteristics of D381X grooved worm wheel butterfly valve
1. The grooved butterfly valve has compact structure, small size, light weight, flexible operation and convenient maintenance.
2. Reliable sealing performance, free from medium injection restriction (two-way sealing);
3. Large flow area, small flow resistance coefficient and large flow capacity;
4. The butterfly plate is radiation-resistant and durable.
If butterfly valve is required to be used as flow control, the main thing is to select the correct size and type of valve. The structure principle of butterfly valve is especially suitable for making large caliber valves. Butterfly valves are not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power plants. Commonly used butterfly valves are butterfly-clip valves and flanged butterfly valves. The clamp butterfly valve is connected between two pipeline flanges by double-head bolts. The flange butterfly valve has flanges on the valve. The flanges at both ends of the valve are connected to the pipeline flanges by bolts.
