Pneumatic valve flange fixed valve industry structure theory _ pneumatic components factory

Pneumatic valve pneumatic pneumatic valve flange fixed overview: flange fixed pneumatic valve is the valve industry pneumatic components factory according to the characteristics of pipeline equipment using pneumatic valve can remove aerodynamic body and seat, online from removal of body, cover and so on pressure parts. When the aerodynamic body and seat after repair, the aerodynamic body and seat into the body can be put into use, especially in the butt welding use maintenance specially for pneumatic valve in the pipeline. Execution standard flange fixed pneumatic valve: design and manufacturing standards: GB12237, API608, API6D, DIN, JIS standards, etc. Structure length standard: GB12221, ASME B16. 10 and so on. The flange standard: GB9113, HG20592, HG20615, JB79 and ASME B16. 5, etc. Butt welding standard: 12224 GB and ASME B16. 25 and so on. Product size: (~ 48 '), NPS 2 inch ~ 48 inches NPS) 。 Product pressure: PN1. 6MPa~42. 0议员( Class150 pounds ~ Class2500 pounds) 。 Products applicable temperature: - 29 ℃ ~ 600 ℃ the valve body material: cast steel ( WCB, LCB CF8 CF8M) Forged steel ( A105, LF2, 304, 316, etc. ) Duplex stainless steel special material, etc. , can also according to customer requirements material production and manufacturing. Within a material: carbon steel ENP plating, Cr13 stainless steel, 304/316 stainless steel, dual phase steel and other materials, can also according to customer need to customize special material. Flange fixed pneumatic valve features: (1) connection structure of simple, reliable and effective seal type, make its * * advantage in using alternative gate valve, globe valve, flow resistance coefficient and the seat is easy to wash and wear. (2) of the flange fixed pneumatic valve design is unique, novel structure, the structure of the valve adopts the top mounted structure, pneumatic, seat, stem, top cover is mounted, and reliable safety, install and use the online maintenance as long as the open cover will reveal a pneumatic and seat, not the body is removed from the pipeline installation, and in the line of welded joint using superior performance is more apparent, for valve repair to save valuable time. (3) the seat with elastic compensation, after the frequent switch, the seat is under the condition of wear and tear, by the back of the spring pre-tightening force, automatic sealing compensation. (4) the body to the overall structure, in the long-term use of the pipeline, inevitably affected by changes in the weather heat bilges cold shrink caused by pipeline to the tensile and compression of the valve, and the intensity of the whole structure is better adapt to the natural situation. (5) valve seat and valve stem seal on the structure, increase the use of safety valve in the operation, and on the other hand, prolong the service life of the valve. 6 flange fixed pneumatic valve can be installed manually worm gear, electric, pneumatic, hydraulic linkage device such as a driver, because of its cover, support for the center of the valve installation and connection, high strength, good rigidity, the stability of the driving device installation and use, has greatly increased, through fire certification. Pneumatic valve flange fixed working medium: water, oil, natural gas, acid medium, high temperature medium, such as seawater environment. Flange fixed pneumatic valve used in oil drilling, food medicine, petrochemical industry, natural gas, steel, electric power, metallurgy, environmental protection, urban construction, papermaking and other fields. Stable performance, safe and reliable. : Q647F pneumatic fixed pneumatic valve Q947H/F/H electric type pneumatic valve
