Butterfly valve disc movement with a wipe, so most of the butterfly valve can be used for medium with suspended solids, depending on the strength of the seal can also be used for powder and granular media. The butterfly valve has a low overall length and overall height, opens and closes fast, has a low fluid resistance when fully opened, and provides sensitive flow control when opened to between approximately 15 ° and 70 °. The butterfly valve The structural principle of the most suitable for the production of large-caliber valves. Under the conditions of the following conditions, Guilong recommended the use of butterfly valves: ①require throttle, adjust the control flow; ② mud media and solid particles containing media; ③ require the valve structure of the short length of occasions; ④ require opening and closing speed of the occasion; Pressure difference smaller occasions. In the two-bit regulation, narrow mouth of the channel, low noise, cavitation and gasification phenomenon, a small amount of leakage to the atmosphere, there are abrasive media, you can choose GuiLi butterfly valve. Under special operating conditions, throttling regulation or require strict sealing, or severe wear and tear, cryogenic (cryogenic) and other conditions when the use of butterfly valves, the need to use special design metal seal with a regulator tri-eccentric or double eccentric butterfly valve . Soft sealing butterfly valve for ventilation dust removal pipeline bidirectional opening and closing and regulation, metallurgy, light industry, electricity, petrochemical systems, gas pipelines and waterways. Metal to metal wire sealing double eccentric butterfly valve for heating, steam supply, water supply and gas, oil, acid and other pipelines, as regulating and intercepting device. In addition to the large-scale pressure swing adsorption gas separation control valve, the two-way pressure butterfly valve can also be widely used in petroleum, chemical, metallurgy, electric power, food, medicine, water supply and drainage, gas transportation and other fields.
Alumina Ceramic Disc
First, the impact resistance - its structure, the panel has a strong resistance, this feature is based on the BSEN438-2/91 sports sphere sag test results, and confirmed by daily practical use.
Second, resistance to scratching - special surface structure, so that the ceramic plate has scratch resistance, even if it is affected by various hard objects, it can maintain the shape without damage for a long time.
Third, wear-resistant - BSEN438-2/91 test, confirmed that the ceramic plate has a strong wear resistance, suitable for heavy objects placed or need frequent cleaning.
Fourth, easy to clean - tight non-permeable surface, so that dust is not easy to adhere to it, so the product can be easily cleaned with the relevant solvent, without any impact on the color.
