[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. For this multi-applicability valve, an external device connected to the circuit board controls the motor through the circuit board to drive the transmission shaft to rotate in the reverse direction. The rotating transmission shaft drives the motor shaft screw connected to the bottom end to rotate in the reverse direction accordingly. Since the motor shaft screw is arranged inside the angled stud, when the motor shaft screw rotates in the reverse direction, the angled stud slowly moves upward by using thread engagement and the limitation of the limit sleeve. The slowly moving angled stud drives the valve ball body to move upward accordingly to release the locking of the water inlet joint. At this time, the liquid quickly flows into the lower valve body and the upper valve body and is discharged from the water outlet joint. This device is convenient for opening the water inlet joint to allow the liquid to pass through.

[0016] 2. This multi-applicability valve uses an external device to control the electric drive and the motor shaft screw to rotate forward. The forward rotating motor shaft screw uses the thread engagement with the threaded groove valve and the limit of the limit sleeve to push the threaded groove valve to slowly move downward. The downward moving threaded groove valve pushes the valve ball to move downward and enter the interior of the sealing slope until the main surface of the valve ball contacts the sealing slope to seal the water inlet connection and block the liquid in the pipeline connected to the water inlet connection from entering the upper valve and the lower valve. This device is convenient for closing the water inlet connection to prevent liquid from passing through. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] By arranging the motor 2 and the circuit board 205, and connecting the circuit board 205 to an external control device, it is convenient to control the forward or reverse rotation of the transmission shaft 204 driven by the motor 2, thereby controlling the opening and closing mechanism 3 to open and close the water inlet joint 104. And by replacing the motor 2 with different torques, it can be applicable to different water pressures. By arranging the shaft seal ring 206 and the connecting seat 208, it is convenient to prevent the liquid in the upper valve body 1 and the lower valve body 103 from leaking out from the connecting seat 208. By arranging the connecting column 201, the fixing plate 202, the second fixing bolt 203 and the fixing nut 207, it is convenient to install and fix the motor 2, and at the same time, the upper valve body 1 and the lower valve body 103 can also be fixed.

[0026] Working principle: When a multi-applicability valve is in use, in the initial state, the lower valve body 103 is arranged at the bottom of the upper valve body 1. A sealing gasket 102 is fixedly connected between the upper valve body 1 and the lower valve body 103. An inlet joint 104 and an outlet joint 105 are respectively fixedly connected to the upper valve body 1 and the lower valve body 103. The upper valve body 1 and the lower valve body 103 are fixed by the first fixing bolt 109, the second fixing bolt 203 and the fixing nut 207, so that the liquid can pass through smoothly. And a valve ball body 302 is placed in the sealing inclined groove 301 arranged at the bottom of the inner cavity of the lower valve body 103. The angular stud 304 fixedly connected to the upper surface of the valve ball body 302 slides up and down in the limiting sleeve 303 fixedly connected to the top of the inner cavity of the upper valve body 1, so as to control the opening and closing of the inlet joint 104 by using the valve ball body 302 to realize liquid cut-off and liquid discharge. At the same time, the motor 2 is connected to the connecting column 201 on the upper surface of the upper valve body 1 by using the fixing plate 202. The transmission shaft 204 arranged at the bottom of the motor 2 is connected and inserted into the angular stud 304 with the motor shaft screw 305, so as to control the lifting of the angular stud 304 and drive the valve ball body 302 to move up and down to close and cut off the liquid or cancel the limit to start liquid discharge; When it is necessary to open the water inlet joint 104 to allow liquid to pass through, first, an external device connected to the circuit board 205 controls the motor 2 to drive the transmission shaft 204 to rotate in the reverse direction. The rotating transmission shaft 204 drives the motor shaft screw 305 connected to the bottom end to rotate in the reverse direction accordingly. Since the motor shaft screw 305 is arranged inside the angled stud 304, when the motor shaft screw 305 rotates in the reverse direction, the angled stud 304 slowly moves upward by means of thread engagement and the limitation of the limit sleeve 303. The slowly moving angled stud 304 drives the valve ball body 302 to move upward accordingly to release the locking of the water inlet joint 104. At this time, the liquid quickly flows into the lower valve body 103 and the upper valve body 1 and is discharged from the water outlet joint 105. This device facilitates opening the water inlet joint 104 to allow liquid to pass through.

[0027] When it is necessary to close the water inlet joint 104 to prevent liquid from passing through, first, the external device uses the circuit board 205 to control the motor 2 to drive the transmission shaft 204 and the motor shaft screw 305 to rotate in the forward direction. The forward-rotating motor shaft screw 305 uses thread engagement with the angled stud 304 and the limitation of the limit sleeve 303 to push the angled stud 304 to slowly move downward. The downward-moving angled stud 304 pushes the valve ball body 302 to move downward into the inside of the sealing inclined groove 301 until the surface of the valve ball body 302 contacts the sealing inclined groove 301 to close the water inlet joint 104 and block the liquid in the pipeline connected to the water inlet joint 104 from entering the upper valve body 1 and the lower valve body 103. This device facilitates closing the water inlet joint 104 to prevent liquid from passing through.
