Detailed Description
The linkage reversing flow guide ball valve shown in fig. 1 comprises a first ball valve 1 and a second ball valve 2, wherein the first ball valve 1 and the second ball valve 2 are three-way reversing ball valves with the same structure; the method is characterized in that: the first ball valve 1 and the second ball valve 2 are respectively installed on the plane of the same channel steel 3 through a vertical adjusting device 8, the center lines of inlet and outlet channels of the first ball valve 1 and the second ball valve 2 are parallel to each other, and the center lines of valve rods 4 of the first ball valve 1 and the second ball valve are superposed and in transmission connection with a worm gear mechanism 5. The vertical adjusting device 8 adjusts the vertical positions of the first ball valve 1 and the second ball valve 2 to ensure the concentricity of the valve rods 4 of the first ball valve 1 and the second ball valve 2, and the worm gear mechanism 5 is driven by an electric, pneumatic or manual device. The first ball valve 1 and the second ball valve 2 are driven by a worm gear mechanism 5 to change directions simultaneously, so that the configuration number of actuators is reduced, the structure is simplified, the cost is reduced, and the synchronism of the change directions is improved.
The valve rods of the first ball valve 1 and the second ball valve 2 are concentrically connected through a coupler, and the worm gear mechanism 5 is in transmission connection with the valve rod of the first ball valve. The worm gear mechanism 5 drives the valve rod 4 to rotate, and drives the first ball valve 1 and the second ball valve 2 to synchronously change directions.
The worm gear mechanism 5 adopts a bevel gear transmission mechanism, the valve rods of the first ball valve 1 and the second ball valve 2 are respectively connected with a driven gear, the two driven gears are simultaneously meshed with a driving gear, and the valve rod 4 of the second ball valve 2 is connected with a driven gear output shaft 6 through a double-thread adjusting pipe 7. Through adjusting double thread adjusting pipe 7, adjust the fit clearance between 6 tip driven gear of output shaft and the driving gear, eliminate first ball valve 1 and 2 valve rod concentricity errors of second ball valve and influence transmission performance.
The vertical adjusting device 8 adopts a double-thread adjusting device, and the lifting adjustment is realized by adjusting an adjusting nut of the double-thread adjusting device.
A double-thread adjusting mechanism 10 is arranged between the bracket 9 of the worm gear mechanism 5 and the upper plane of the channel steel 3. The height position of the shell of the worm gear mechanism 5 is positioned by adjusting the double-thread adjusting mechanism 10, so that the worm gear mechanism 5 and the valve rod 4 are conveniently installed.
