High-performance butterfly valve is widely used in petroleum, chemical, electric power, metallurgy, food, medicine, textile, papermaking and other industries. It can be installed at a temperature of ≤425℃, and the medium is gas, air, steam, water, seawater, oil, etc. Industrial pipe network is used for adjusting flow and cutting off medium.
The driving forms include manual, worm gear, pneumatic, hydraulic, electric, electro-hydraulic linkage and other actuators, which can realize remote control and automatic operation. Metal hard seal butterfly valve series products are long-life, energy-saving butterfly valves. Its structure adopts three-dimensional core design principle, the valve seat adopts a multi-layer structure compatible with hard and soft sealing, exquisite processing and advanced technology. This product is composed of main components such as valve body, butterfly plate, multi-level valve seat, valve stem and transmission mechanism. Therefore, it is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage and other corrosive media pipelines.
The high-performance butterfly valve makes the space movement trajectory of the sealing surface idealized. There is no friction and interference between the sealing surfaces, and the sealing material is selected appropriately, so that the butterfly valve has sealing performance, corrosion resistance, high temperature resistance and wear resistance. Obtained a reliable guarantee. Its main features are as follows:
1. The opening torque is small, flexible and convenient, labor-saving and energy-saving.
2. The three-dimensional braided core structure makes the butterfly plate tighter and tighter, and its sealing performance is reliable and leak-free.
3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc.
The installation position of the high-performance butterfly valve should be convenient for maintenance, and there should be room for adjustment and operation of accessories. In order to ensure the safe operation and easy maintenance of the high-performance butterfly valve, it is recommended to install a bypass pipeline. The high-performance butterfly valve should be cleaned of impurities in the pipeline before installation After installation, the valve should be fully opened for thorough cleaning and leak detection. During the maintenance of high-performance butterfly valves, the butterfly plate, the sealing surface of the valve seat and the piston sealing ring of the pneumatic actuator should be inspected. If damage is found, it should be repaired or repaired in time. Exchange to ensure the normal operation of the system.
