BQ340F double eccentric valve

Shanghai crown ring double eccentric ball valve manufacturing Co., Ltd. production, BQ340F double eccentric ball valve and seat completely out, eliminating the seal wear, to overcome the traditional ball valve seat and the sealing surface of the ball is always the problem of wear and tear, non-metallic elastic material is embedded in the metal seat, the seat metal surfaces are well protected. I. Product Overview: double eccentric hemisphere an eccentric ball valve, eccentric ball and seat, when the valve stem rotates the self-centering in the common trajectory, the closing process more closed more tight, fully achieve a good sealing purposes. The valve ball and seat completely out, eliminating the wear ring to overcome the traditional ball valve seat and the sealing surface of the ball is always the problem of wear and tear, non-metallic elastic material is embedded in the metal seat and seat metal surfaces are well protected. This product is particularly suitable for steel, aluminum, fiber, tiny solid particles, pulp, coal ash, petroleum gas and other media Second, product characteristics: 1, the structure of eccentric deeds tight tight principle reached by the gate drive mechanism, regulation, Close the purpose of sealing the metal surface contact with the sealing ring with a hard surface, double eccentric structure in possession of the ball when you turn the valve located in the room, a large flow cross-section, and the valve will not be washed, not be washed off the spool, when opening the valve spherical core along the seat progressive and effective removal of obstacles to scaling, to achieve a reliable seal. It is easy to scale two-phase flow of solid precipitation is particularly effective delivery of Francis 2, the valve hemisphere double metal, base metal surfacing on different alloys, surfacing with a corresponding valve seat by special treatment, a combination of a sealing surface corrosion , various types of wear-resistant, high strength, etc., to meet the needs of different occasions 3, sealed tight, transportation of hazardous gases up to zero leakage 4, left spool of sealing compensation, while the valve do wear after a little time off and then rotated , any reliable seal, extended service life. In addition, users will be compression nut off, adjust or replace the seat post is still available, to avoid the failure of the valve seal, the entire scrapped three drawbacks, because welding different alloys (or a combination of ball) bi-metal seal pair matching It can be used for wear and corrosion, high temperature and demanding sealed case 1, general-purpose valves: Specification DN40-1600. Suitable for sewage treatment, pulp, urban heating heating stringent requirements of the occasion 2, oil chemical special valves: Specification DN40-1600. It applies to crude oil, heavy oil and other oil products, chemical industry weak corrosion, two mixed flow medium 3, gas special valve: Size DN40-1600. It applies to gas, natural gas, liquefied petroleum gas transportation control 4, the slurry for valves: Specification DN40-1600. Suitable for liquid, solid or liquid two-phase flow transport chemical reactions or crystallization fouling industrial pipeline 5, coal ash for valves: Specification DN40-1600. For power plants, hydraulic slag or gas pipeline controlled four, the implementation of standards: Design: GB12237-89 flange connection: GB / T17241.6-1998, GB / T9115 (steel) structure Length: GB12221-89 double eccentric Ball valve http://www.ghval.com/productlist/qf-1.html http://www.ghval.com/product/qf/104.html Shanghai
