An overview of the internal thread pneumatic ball valve (3)

thread pneumatic ball valve, welding into integral style ( Style) , two stages and three stages of the connection. Body putting-in-service proactively in Taiwan to introduce advanced technology, reasonable structure, beautiful appearance. Elastic sealing structure, reliable pneumatic valve seat seal, easy opening and closing. Pneumatic valve stem seal structure, download, when an abnormal pressure pneumatic valve chamber, pneumatic valve stem will not be rushed out. Type 2, 3 type pneumatic ball valve connection form another ass ( Weight) Socket welding ( The southwest) And can stand with the international standard ISO platform and locking device. Can be set up ° switch positioning mechanism, according to the need, in order to prevent the abuse of locking, drive mode: manual, electric, pneumatic application: pneumatic welding pneumatic ball valve and ball valve with PN. Such as internal thread? 。 MPa, working temperature - 吗? ℃ ( Ptfe seals to strengthen) Or - 吗? ℃ ( A ring of polystyrene from right) All kinds of pipeline, cut or connected to the media. Use different materials, can be respectively suitable for water, steam, oil, nitric acid, acetic acid, etc. Features:. Fluid resistance is small, resistance with the same barrel length factor. 。 Simple structure, small volume, light weight. 。 Compact and reliable, pneumatic valve sealing surface material widely used plastic, also widely used in vacuum system of seal. 。 Easy to operate, open and close quickly, from open to close as long as the rotating ° long, is advantageous for the remote control. 。 Convenient maintenance, simple pneumatic ball valve, sealing ring are generally activities, removable more convenient. 。 In full open or full close, the sphere and the pneumatic valve seat sealing surface and the dielectric isolation, medium through, can not cause erosion of pneumatic valve sealing surface. 。 Applicable scope is wide, from small to several millimeters, diameter, rice, from high vacuum to high pressure can be applied. Standard: design and manufacturing standards: in accordance with the ASME B. AFI structure length standard: GB/T - Pipe thread end: ASME B. , BS, DIN/ISO/BSP, conform to the ISO standard /, JISB pressure temperature rating: GB/T - Test: GB/T -
