Trunnion ball valves belong to pipeline equipment

Trunnion ball valves belong to pipeline equipment. It solves complex valve structure, poor sealing performance, operating torque, short life technical problems. The trunnion ball valve includes a valve stem in the valve body equipped with, at one end is connected with a poppet valve stem, the Instrument valves stem at the other end is connected to a handle, said valve stem and ball joints provided There trunnion, said trunnion diameter greater than the stem diameter and smaller than the cross-sectional diameter of the spherical valve body, said valve body and connected at the stem is provided with a locking structure, said outer poppet connected with ball joints, ball joints at the outer ends with a card sleeve structure. The utility model has the advantage of: rational design, solid structure, high sealing performance, can effectively reduce operating torque and prolong life.
