The invention relates to a double-channel variable-flow spherical forged steel all-welded ball valve which comprises a main pipeline and two branch pipelines arranged at one end of the main pipeline, a first spherical shell is arranged on each branch pipeline, a base is fixedly installed on the periphery of each first spherical shell, and a second spherical shell is fixedly installed on the base. A first ball body is rotationally arranged in the first spherical shell in a sealed mode through a bottom bearing, the bottom bearing is arranged in the base, a first channel is formed in the first ball body, a fine adjustment mechanism is arranged in the first channel, and the fine adjustment mechanism is connected with a meshing triggering mechanism installed on the first ball body; due to the fact that the flow is gradually increased in the process that the first ball body rotates by a certain number of turns, the flow value reaches the maximum value when the first channel and the second channel are completely communicated, the accuracy of flow adjustment of the ball valve is greatly improved, and the ball valve is suitable for application and popularization.
Description
technical field [0001] The invention relates to a valve, in particular to a ball-shaped forged steel full-welded ball valve with dual channels and variable flow. Background technique [0002] A ball valve is a valve that uses a ball valve core with a circular through hole as an opening and closing part, and the ball valve core rotates with the valve stem to realize the opening and closing action. It can also be used for fluid regulation and control. There is a strong shear force between the V-shaped ball core and the metal valve seat of hard alloy surfacing, which is especially suitable for media containing fibers, tiny solid particles, etc. [0003] There are various types of ball valves, which are widely used in various industries such as petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets and people's daily life. Usually, when the ball valve is turned from the closed state to the maximum open state, the rotation angle of the valv...
