Problems solved by technology

The existing ball valve cannot be repaired online when the valve fails, while the top-mounted floating ball valve only needs to remove the screws of the valve cover, and then the ball and seat assembly can be taken out, so that new parts can be replaced and damaged parts can be repaired online. Repairs save time and minimize losses in production

Abstract

The invention discloses a top entry floating ball valve capable of being maintained on line. The top entry floating ball valve capable of being maintained on line comprises a valve body, a valve deck matched with the valve body, a ball body, a valve rod, a locating screw, a belleville spring and a handle. The ball body is arranged in the valve body, the valve deck is arranged at the upper portion of the valve body and forms a containing cavity, and the ball body is sealed in the containing cavity. The valve rod penetrates from the top of the valve deck and is detachably connected with the ball body. Valve rod packing is arranged between the top end of the valve deck and the valve rod. The valve rod is provided with the belleville spring in a sleeved mode and the belleville spring presses the valve rod packing. The connection end of the handle is fixed to the top end of the valve rod in a sleeved mode through the locating screw. A thrust pad is arranged between the bottom of the ball body and the valve body in a cushioning mode and used for guaranteeing the stability in the opening and closing processes of the ball valve. According to the top entry floating ball valve capable of being maintained on line, on-line disassembly and assembly on a pipeline and fast replacement of damaged parts can be achieved.

Description

technical field [0001] The invention relates to a top-mounted floating ball valve capable of online maintenance. Background technique [0002] At present, top entry floating ball valves are widely used in oil and gas pipelines, as well as petrochemical, electric power, nuclear power, and papermaking industries. The existing ball valve cannot be repaired online when the valve fails, while the top-mounted floating ball valve only needs to remove the screws of the valve cover, and then the ball and seat assembly can be taken out, so that new parts can be replaced and damaged parts can be repaired online. Repairs save time and minimize losses in production. Contents of the invention [0003] Purpose: In order to overcome the deficiencies in the prior art, the present invention provides a top-mounted floating ball valve that can be maintained online. Through this ball valve, the purpose of online disassembly and assembly on the pipeline and rapid replacement of damaged parts c...
