Structural characteristics: 1. No nylon butterflies marketing boards, with excellent mill reduction, self-lubricating, General operating torque than a butterfly valve to reduce sales by more than 40%. 2. Sealing surface wear resistance (nylon wear resistance of copper is seven times), can significantly prolong life. 3. Nylon material not has any toxicity, as well as antibacterial and anti-fungal, anti-corrosion, with the growing importance of green environmental requirements. 4, widely used for fuel, water, steam, and corrosive media of the road, cutting off access or medium. 5, advanced sales without linking technology to ensure a completely metal and dielectric isolation, improve the reliability of the product, Butterfly Valve makes it easier maintenance. 6, much lower than the price of stainless steel valves, can significantly reduce the cost of the project. 7, this product is particularly applicable to fresh water, water, gas, oil, alkali and salt, acid and other organic compounds. 8, and the pipeline flange connecting with the existing size of the butterfly valve products national standards.

Double eccentric semi-Ball Valve is a new type of valve, is the solution for resolving such as pulp and two-phase media conveying technical issues and the research and development of new products. This product fills a variety of valves a blank domestic product, the structure adopted by eccentric-wedge tight theory that the drive to achieve Gate tight regulation, hoist role. The new product mix, stable performance, opened quickly lightweight, wear automatic compensation, sealed reliable and durable, easy to adjust maintenance; seamless structure circulation larger than the closing valves, butterfly damper valves, and other small, small pressure-relief system; able to get rid of scaling, Hoist convenience, no "dead zone" to overcome the valve, the valve and closing valves scaling, easy plug and easy to leak out, defects such as short life, showing the unique advantages. Double eccentric Semi-ball valve series products and implementing a national standard GB9113. 8-11-88 size flanged connection, easy to install valves and replace the existing varieties; Users can also connect the size of a series of arrangements for the production, adapted to different conditions and mineral needs.

BHS41X-16 common type device to prevent backflow check valve in series two. But it is a seal broken; another had a role sealed to prevent reflux. But two valve seal destroyed, it will have lost only to function, its safety and reliability relative badly working principle is simple. BHS41-16A Safe in the backflow prevention device on the basis of the ordinary-middle drainage device, Even though the two valve seal destroyed, can also prevent the return of the role of pollution. A normal supply: a. urban living clean water from the first grade through the drainage valve on the second level of the check valve to export water users. first-class high-pressure valve imports by the high-pressure water hose into the drainage divide with superior vena, and divide cavity and the first export-check valve (the second check valve imports), so that its existence as a pressure difference, promoting lower flap valve, drainage for the closure of backflow prevention device normal water supply; b. When the pipeline after the valve without the users, static water. If the pressure of imports remained unchanged after its existence pressure, drainage devices are still closed; C. If the import pressure drop before and after its pressure dropped to a certain value, the flap valve spring to promote progressive, open drainage pressure relief device, Relief and imported pressure to restore the margin, were closed for drainage. 2. Seal failure: backflow prevention device after increased pressure on the network, more than before the import pressure valve, If the second check valve seal intact no leakage, high-pressure water will not turn the clock back, the next drainage divide for pressure maintenance, closed drainage device, pressure relief. When the second-valve damage have sealed leaks, the second valve before increasing the pressure, caused drainage divide with the pressure difference decreased to open drainage, drainage venting; At this time, If the first-class check valve while sealing, the second-valve back to the high-pressure water has been venting decompression, Hence, it will not turn the clock back to the first-class check valve. 3. If the process of water pressure drop of water, drainage divide with the upper pressure drop Drainage Control safety spring to promote spool open drainage for drainage. When the pressure of imports dropped to zero, or negative pressure, drainage devices are fully opened, water discharges, air entered the drainage from the vacuum chamber, thereby preventing backflow siphon phenomenon.

valve is hydrophobic steam heating equipment and steam pipes along the important parts of the energy-saving products, it uses the nozzle to cut expenditure, so that blood pressure through condensation water into secondary steam so that condensation water use is secondary. It can be used to control surface water discharges, the minimum flow control pipeline system, it also widely used in petrochemical, textile, dyeing, paper making and other industrial sectors using steam pipeline equipment.

The valve is steam heating equipment and steam pipe important accessories online, automatically excluded from condensation of water, preventing steam leak, equipment to improve the thermal efficiency, steam heating system in the best possible conditions of work and energy conservation plays an important role. Movement sensitive, reliable and has an automatic air emission devices. Displacement of large, small amount of leakage. Condensation can be excluded for water, drainage temperature up to saturation temperature. Backpressure rate of import pressure can reach 80%.

Main technic-al parameters


valve


Steam for equipment, pipelines and other equipment steam heating system for automatically excluded from condensation of water, air and gas condensate not, and to prevent the leakage of steam, improving thermal efficiency. The high-performance products to high-parameter, discharge, a small amount of leakage, which applies to high-temperature, high-pressure conditions for industrial use. Can be used for sub critical state. Excellent performance and reliability, and leading the country status.
