[0026] An internal lifting groove for assembling the side-mounted lifting locking mechanism is formed on the inner top surface and the inner bottom surface of the main valve body 1, and an internal lifting wheel 8 for transmission connection between the external valve rod 4 and the side-mounted lifting locking mechanism is movably assembled in the internal lifting groove.

[0027] In order to improve the guiding property of the internal lifting, the side-mounted lifting locking mechanism comprises an integral structure guide rod 9 fixed in the internal lifting groove and an internal lifting block 10 slidably sleeved on the outer side of the guide rod 9, and an arc-shaped thread groove matched with the internal lifting wheel 8 in thread is formed on the inner side surface of the internal lifting block 10.

[0028] The internal lifting block 10 is lifted in the internal lifting groove by the internal lifting wheel 8 through rotation.

[0029] The lifting amplitude is adjusted according to the thread angle of the arc-shaped thread groove of the transmission surface of the internal lifting wheel 8 and the internal lifting block 10.

[0030] In order to cooperate with the lifting engagement lock, so as to fix the assembly angle, the inner lifting block 10 is provided with an outer locking tooth groove near the side wall of the assembly ball head 6, which cooperates with the inner limiting tooth groove.

[0031] In order to cooperate with the lateral assembly, the lateral assembly cylinder 2 is internally provided with an inner limiting cavity for installing the assembly ball head 6, and the inner top surface and the inner bottom surface of the lateral assembly cylinder 2 are symmetrically provided with a circular inner screw hole in communication with the inner limiting cavity, and the circular inner screw hole is internally screwed with an inner limiting cylinder 11 for limiting the assembly ball head 6.

[0032] After the assembly ball head 6 is inserted into the inner limiting cavity, the inner limiting cylinder 11 is screwed from the upper end and the lower end respectively to install and limit the assembly ball head 6.

[0033] In order to improve the safety inside the valve, the inner limiting cylinder 11 is elastically assembled with a water hammer eliminator inside.

[0034] In order to cooperate with the external control, the outer valve rod 4 is externally sleeved with an integrated external control gear 12, and the outer side of the transmission wheel 8 is provided with an annular transmission tooth groove 13 which is engaged with the external control gear 12.

[0035] The outer valve rod 4 drives the external control gear 12 to rotate, thereby driving the transmission wheel 18 to rotate, and the transmission wheel 18 drives the inner lifting block 10 to ascend and descend along the guide rod 9.

At this time, the inner side of the lateral flipping locking rod 18 is squeezed and flips outward. The lateral flipping locking rod 18 squeezes the inner wall of the longitudinally mounted through hole 15, improving the assembly stability and firmness.

It adopts a split-type structural layout for easy assembly and disassembly. A side-mounted lifting and locking mechanism controlled by an external valve stem 4 is provided inside the main valve body 1. This mechanism can simultaneously lock the angle of the assembly ball head when the external valve stem 4 rotates, thereby improving the structural stability and robustness of the valve after locking, and making control more convenient. The assembly ball head 6 on one side of the lateral conveying pipe 3 is inserted into the lateral assembly cylinder 2 and movably assembled with both sides of the main valve body 1.
