Firstly, after the valve body 10 is fixedly connected with an input pipe and an output pipe, the upper clamping piece 42 and the lower clamping piece 41 are pushed to slide towards one side of the flange 15 and are propped against the flange 15, then the upper outer cover 46 is downwards slid, the toothed bar 44 on the surface of the upper outer cover 46 is driven by the toothed bar 47 to rotate anticlockwise in the downwards sliding process, the linkage gear 47 can drive the other toothed bar 44 to move upwards by anticlockwise rotation, so that the lower outer cover 45 connected with the upper outer cover 46 and the lower outer cover 45 move upwards, after the upper outer cover 46 and the lower outer cover 45 are clamped together, the inner walls of the upper outer cover 46 and the lower outer cover 45 are propped against the flange 15, and then the upper outer cover 46 and the lower outer cover 45 are respectively fixed with the upper clamping piece 42 and the lower clamping piece 41, and the outer cover unit 40 is covered and fixed outside the flange 15 to shield and protect the upper outer cover;
Then, the rotary table 312 is rotated, the outer sphere 21 rotates along with the rotary table through the outer valve rod 311, and since the inner control assembly 32 is assembled in the outer control assembly 31, when the rotary table 312 rotates, the rotary table rotates along with the outer sphere 21, so that the inner sphere 22 rotates along with the outer sphere 21, the outer sphere 21 rotates to a position required to be communicated, and when the rotary table rotates to the position that three through holes 23 are simultaneously opened, a medium entering the outer sphere 21 keeps a relatively even state and enters two output pipes through the two through holes 23;
When the required flow rates of the two output pipes are different, the limiting insert block 326 is pulled out from the vertical groove 313, one of the deflector rods 325 is pulled up, then the middle disc 322 is rotated by the deflector rod 325, the inner valve rod 321 rotates together with the inner ball 22, the rotating position of the inner ball 22 is determined by the scale mark 323 indicated by the position arrow 324 in the rotating process, after the inner ball 22 rotates to a proper position, the pulled deflector rod 325 is reset, then the limiting insert block 326 is pushed inwards again to be inserted into the vertical groove 313 at the corresponding position, so that the middle disc 322 and the turntable 312 are fixed together, at the moment, the medium entering the outer ball 21 can flow out through the shielded through hole 23, the flow rate through the non-shielded through hole 23 can be increased, the different flow rate requirements are further realized, when the one-way circulation is switched, the position of the inner ball 22 is reset, and when the one-way circulation is required, the range of the through hole 23 can be shielded through the inner ball 22, and the flow rate is reduced.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
