Lug type butterfly structure characteristics and application scope of pneumatic valve

the lug type butterfly pneumatic valve is introduced:
the wafer lug butterfly butterfly plate installed on the diameter of the pipe of pneumatic valve. In the cylindrical channels of pneumatic valve pneumatic butterfly valve body and disc butterfly plate around the axis of rotation, rotation Angle for ° - Between °, rotate to °, the pneumatic valve is fully open.

lug type butterfly pneumatic valve structure:
wafer butterfly valve pneumatic valve pneumatic valve is in the stud connection in place between two pipe flanges, its simple structure, small volume, light weight, only by a few parts. And simply rotate ° rapid opening and closing, simple operation, at the same time, the pneumatic valve has good flow control characteristics. Butterfly pneumatic valve in the fully open position, the butterfly plate thickness is medium flows through the only pneumatic valve body resistance, and so by the pneumatic valve pressure drop is small, it has good flow control characteristics. Butterfly pneumatic valve seal and metal sealing machine has two sealing type. Elastic sealing pneumatic valve, sealing ring to be set on the pneumatic valve body or attached to the butterfly plate peripheral.

lug butterfly type pneumatic valve to the scope of application:
butterfly pneumatic valve not only in the oil, gas, chemical industry, water treatment and other general industrial used widely, but also applied to the cooling water system of thermal power plants.
used in sulphuric acid industry gas pipeline: before the furnace blower entrances, relay fan entrances and exits, electric mist series pneumatic valve and unicom, S main blower entrances and exits, converter, using gas preheater gateway such as adjusting and globe.
used in the sulphuric acid systems in burning sulfur, transformation, dry absorption section, is the first selection of sulphuric acid plant with pneumatic valve brand, is considered by the masses of users, sealed performance is good, work light, corrosion, high temperature resistant, convenient operation, flexible, safe and reliable using the pneumatic butterfly valve, received a large number of promotion of use.
lug type butterfly pneumatic valve is widely used in: chemical, petrochemical, metallurgy, medicine, food and other industries SO, steam, air, gas, ammonia, CO gas, oil, water, salt water, alkali liquor, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media on the pipeline as the adjusting and intercepting device is used.

the structure characteristics of lug type butterfly pneumatic valve:
the unique design of three-way eccentricity between the sealing surface friction drive, prolong the service life of pneumatic valve.
(2) generated by the torque of the elastic seal.
3. Clever wedge design make the pneumatic valve has closed more and more tightly automatic sealing function of seal face between with compensatory, zero leakage.
4. Small volume, light weight, light operation and ease of installation.
(5) according to user requirements with pneumatic, electric devices, meet the needs of the remote control and programmed control.
6 replacement parts material can be applied to all kinds of medium, and can be carried out lining anticorrosion ( F, GXPP, PO, etc. ) 。
