Full Bore eccentric half ball valve is a novel, is to solve the two-phase solution and pulp and other media delivery of technical problems and developed a new product, the product to fill a variety of blank valve localization series product, which uses the structure of the eccentric - wedge principle, to close the gate through the transmission mechanism, regulation, opening and closing action. This product is a novel structure, stable performance, quickly turned light, automatic wear compensation, sealing reliable and durable, easy to adjust maintenance; large straight-through flow area of ??the structure, the more shut-off valves, butterfly valves and other small damping and small system down; can rid themselves knot scale, open and close easily, no "dead zone", to overcome the gate valve, ball valve, globe valve and so easy to scarring, easy to plug, easy to leak, short life and other defects, showing the unique advantages. Double eccentric semi-ball series, and implement national standards GB9113,8-11-88 size series flange connection, easy to install and replace the existing valve varieties, can also arrange production according to size series connection the user needs to adapt to the different mining conditions required under.
