Grooved Butterfly Valve

Description of Grooved Butterfly Valve‌

Grooved Butterfly Valve‌ is an industrial equipment that adopts worm gear and worm drive. Through the rotation of the cam, the contacts on the signaling device are pressed down or released according to the predetermined position, thereby outputting “on” and “off” electrical signals to display the butterfly valve. The opening and closing status. This valve is designed to be small, lightweight, easy to disassemble and service, and can be installed in any position.

The structure of the grooved butterfly valve is simple and compact, it can open and close quickly with 90° rotation, has small operating torque, is labor-saving and lightweight. Its flow characteristics tend to be linear and have good regulating performance. In addition, the grooved butterfly valve can be opened and closed tens of thousands of times, has a long life, is completely sealed, and has zero gas test leakage. It is widely used in water supply and drainage, fire protection, air conditioning, gas, petroleum, chemical industry, water treatment, municipal administration It plays the role of controlling fluid in pipeline projects such as shipbuilding and shipbuilding. Grooved butterfly valves are produced because they are fast, easy, safe and reliable to install, are not restricted by the installation site, are easy to repair and maintain pipes and valves, have vibration and sound insulation, and have non-axial pipe connections within a certain angle range, solving the problem of temperature differences. It causes problems such as thermal expansion and contraction, and is widely used in various fields.

Advantages of Grooved Butterfly Valve‌

1. Careful selection of materials, not easy to damage: good sealing, corrosion-resistant material, prevent leakage;
2. It is easy to open and close. It is recommended for quick installation, precise screw thread of the valve, no slip buckle;
3. Durable and stable performance: good oxidation resistance, not easy to rust in humid environment, valves are tightly connected, strong pressure resistance, and good sealing;
4. Heavy body casting, thickened valve body: thickening and thickening the body, the fluid is smoother, effectively preventing magazine precipitation, and the appearance is beautiful;
5. Spray painting process, beautiful valve body, spray painting treatment, low pressure casting, the overall appearance is smooth and beautiful, delicate and smooth, the valve body is thickened, generous and beautiful.
Working principle:
1. This series of butterfly valves mainly consists of handle, valve shaft, valve body, O-ring, butterfly plate, positioning plate, etc.
2. Rotate the handle to drive the valve shaft and butterfly plate to control flow and open and close. 3. In the direction of handle rotation, turn the handle clockwise to close the valve, and turn the handle counterclockwise to open the valve.
