AWWAC504 adjustment characteristics of pneumatic valve

AWWA C 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. The pneumatic valve average installation. Wafer butterfly valve pneumatic valve has 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.
AWWA butterfly pneumatic valve to the clamp C
use metal sealing pneumatic valve generally live longer than elastic sealing pneumatic valve, but it is hard to be completely sealed. Metal sealing can adapt high working temperature, elastic seal has the defect of being limited by the temperature.
if required control pneumatic valve used as flow control, mainly is the right choice of size and type of pneumatic valve. Adjusting the structure principle of pneumatic valve is especially suitable for production of large diameter pneumatic valves. 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.
the commonly used control pneumatic valve with adjustment to the clamp pneumatic valve and flanged butterfly valve two kinds. Wafer butterfly valve pneumatic valve pneumatic valve is in the stud connection in place between two pipe flanges, the flange type butterfly is pneumatic valve pneumatic valves with flange, bolts on the pneumatic valve flange connection on the pipe flange on both ends.
AWWA C and brake performance of the pneumatic valve is
nominal pressure, nominal diameter of the same normal butterfly pneumatic pneumatic valve and gate valve which rigor is better, not easy to leak?
brake of the pneumatic valve closure than butterfly pneumatic valve is better, but there is also a manufacturer of pneumatic valve butterfly airtight good performance.
the large gate pneumatic valve body, take up the space is large.
butterfly pneumatic valve body volume is small, small footprint.
specific selection, consider the temperature of medium, pneumatic valve sealing and packing. The rules and regulations of the
nominal diameter greater than the pneumatic valve with disc.
rubber to the clamp butterfly pneumatic valve is the state-level key new products, high-performance manual adjustment of the pneumatic valve USES a double eccentric and a special oblique elliptic cone sealing structure. Solve the traditional eccentric butterfly pneumatic valve in the opening and closing ° ~ ° seal face is still in the sliding contact friction moment of ills, realize the butterfly plate in open the instant sealing surface, the separation, close contact with the sealing effect, achieve prolong service life, sealed performance is the best.
AWWC butterfly pneumatic valve USES the
used in sulphuric acid industry gas pipeline: before the furnace blower entrances, relay fan entrances and exits, pneumatic valve, electric mist series 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.
are widely used in: chemical, petrochemical, metallurgy, medicine, food and other industries SO, steam, air, gas, ammonia, CO gas, oil, water, salt water, alkali liquor, sea water, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media on the pipeline as the adjusting and intercepting device is used.
AWWA butterfly pneumatic valve structure C
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. ) 。
7) continuous structure diversification, clamp, flange, butt welding.
