Description

Technical Field

[0001] This application belongs to the technical field of valves, and particularly relates to a floating ball valve. Background Art

[0002] The reason why a floating ball valve is called a floating ball valve is that the closing member of this valve is a sphere, and the sphere is not supported by any other components except being supported by two sealing rings used for sealing, so it is called a floating ball valve. When the floating ball valve needs to be closed and opened, generally, an operator rotates the operating grip above the ball valve body to open and close the valve.

[0003] The existing publication number is CN219692414U, which discloses a floating ball valve, including a valve body. The outer wall of the valve body is movably connected with bolts, the inner wall of the valve body is movably connected with a valve stem, one end of the valve stem is fixedly connected with a sphere, a limiting mechanism is movably installed at the bottom of the valve stem, a second clamping groove is formed on the outer wall of the valve body, an anti-blocking mechanism is movably installed on the inner wall of the valve body, and a rubber pad is installed on the inner wall of the valve body.

[0004] Although the above floating ball valve solves the problem that the valve stem of the ball valve is not fixed, which may cause the valve to be opened after being closed due to accidental touch, the length of the valve stem of the ball valve cannot be adjusted in time, and it is impossible to control the ball valve quickly, labor - savingly. Summary of the Utility Model

[0005] The purpose of this application is to provide a floating ball valve for the above - mentioned existing technical problems, which can adjust the length of the valve stem on the ball valve in time, so that the user can conveniently and labor - savingly control the ball valve through the valve stem.

[0006] This application provides a floating ball valve, including a valve body and a flange. It further includes:

[0007] A valve stem seat, which is installed on the valve body;

[0008] An adjusting assembly, which is installed on the valve stem seat;

[0009] A locking assembly, which is installed on the adjusting assembly;

[0010] Among them, the adjustment component includes an adjustment block, an adjustment seat, an adjustment frame, a first rotating shaft, a lead screw, a guide rod, a moving block, an adjustment cylinder, and a driving component. The adjustment block is installed on the valve stem seat, the adjustment seat is installed on the adjustment block, an adjustment cavity is provided in the adjustment seat, the adjustment frame is installed on the adjustment seat, the first rotating shaft is installed on the adjustment frame, the lead screw is installed on the first rotating shaft, the guide rod is installed on the adjustment frame, the moving block is installed on the lead screw, the adjustment cylinder is installed on the moving block, and the driving component is installed on the first rotating shaft.

[0011] When it is necessary to adjust the length of the valve stem, the driving component starts to work and drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the lead screw to work. When the lead screw rotates, the moving block can displace on the lead screw under the guidance of the guide rod. The displacement of the moving block on the lead screw can adjust the position of the adjustment cylinder in the adjustment seat until the position of the adjustment cylinder in the adjustment seat fits the user. At this time, the user can hold the adjustment cylinder and rotate it to control the switch of the valve. The adjustment component can timely adjust the length of the valve stem on the ball valve, enabling the user to conveniently and labor-savingly control the ball valve through the valve stem.

[0012] Further, the driving component includes:

[0013] A first bevel gear, which is installed on the first rotating shaft;

[0014] A second rotating shaft, which is installed on the adjustment frame;

[0015] A second bevel gear, which is installed on the second rotating shaft;

[0016] A driving disk, which is installed on the second rotating shaft;

[0017] A control rod, which is installed on the driving disk.

[0018] When it is necessary for the driving component to drive the first rotating shaft to rotate, the user holds the control rod to control the driving disk to rotate. The rotation of the driving disk drives the second rotating shaft to rotate. At this time, the second rotating shaft drives the second bevel gear to rotate. The second bevel gear meshes with the first bevel gear to drive the first bevel gear to rotate. The rotation of the first bevel gear drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the lead screw to rotate and work. The driving component makes it more convenient and efficient for the user to adjust the position of the adjustment cylinder in the adjustment seat.

[0019] Further, the adjustment component further includes:

[0020] Limit holes, which are provided on the adjustment cylinder, and there are several limit holes;

[0021] A jack, the jack is arranged on the adjusting base;

[0022] A bolt, the bolt passes through the jack on the adjusting base and is inserted into the limiting hole.

[0023] When the position of the adjusting cylinder on the adjusting base is adjusted, the user inserts the bolt through the limiting hole and inserts it into the jack corresponding to the limiting hole to fix the positions of the adjusting cylinder and the adjusting base, avoiding the position deviation of the adjusting cylinder in the adjusting base when the user holds the adjusting cylinder and rotates, which affects the user's rotation to control the switch of the valve.

[0024] Furthermore, a diversion groove is arranged on the adjusting base.

[0025] Due to the diversion groove arranged on the adjusting base, the diversion groove can timely drain the water infiltrated into the adjusting base, avoiding the accumulation of water in the adjusting cavity of the adjusting base, which affects the expansion and contraction of the adjusting cylinder, and improving the stability of the adjustment of the adjusting cylinder in the adjusting base.

[0026] Furthermore, the locking assembly includes:

[0027] An installation groove, the installation groove is arranged on the adjusting block;

[0028] A compression spring, the compression spring is installed in the installation groove;

[0029] A fixed disk, the fixed disk is installed on the compression spring;

[0030] A rotating disk, the rotating disk is installed on the fixed disk;

[0031] A limiting disk, the limiting disk is installed on the valve stem seat;

[0032] A locking groove, the locking groove is arranged on the limiting disk, and a plurality of locking grooves are evenly distributed around the axis of the limiting disk;

[0033] A locking block, the locking block is installed on the rotating disk, and the locking block can be inserted into the locking groove.

[0034] After the user finishes rotating the valve stem, unlock the rotating disk on the adjusting block. A plurality of locking grooves are evenly distributed around the axis of the limiting disk. At this time, the compression spring releases the compressed and rebounded force to push the locking block into the corresponding locking groove to lock the position of the adjusting block. At this time, the user cannot rotate the valve stem, avoiding the user's misoperation to open or close the valve.

[0035] Furthermore, the locking assembly further includes:

[0036] A dial block, the dial block is installed on the rotating disk;

[0037] A limiting groove, the limiting groove is arranged on the adjusting block.

[0038] When the user needs to rotate the valve stem to control the switch part, the user can hold the dial block and lift it to squeeze the compression spring with the fixed disk. At this time, the user can hold the dial block and rotate it to drive the rotating disk to rotate on the fixed disk until the dial block is inserted into the limiting groove. At this time, the locking block is not inserted into the locking groove, and the user can hold the valve stem and rotate it. When the user needs to lock the adjusting block so that the user cannot rotate the valve stem, the dial block is pulled out of the limiting groove, and the compression spring will rebound and reset to drive the locking block into the corresponding locking groove.

[0039] The beneficial effects of this application are:

[0040] 1. The adjusting component can timely adjust the length of the valve stem on the ball valve, so that the user can conveniently and labor-savingly control the ball valve through the valve stem;

[0041] 2. The driving component makes it more convenient and efficient for the user to adjust the position of the adjusting cylinder in the adjusting seat;
