Description

Technical Field

[0001] The utility model relates to the technical field of V-ball valves, and particularly relates to a hard-sealed V-ball valve which is convenient to adjust. Background Technique

[0002] The sphere of a V-ball valve is usually a special design. Different from traditional ball valves, it has a V-shaped groove on the sphere, so that a seal can be formed inside the groove when the ball valve is closed. This design can provide better sealing performance and is especially suitable for the cut-off and control of fluids.

[0003] As disclosed in a V-ball valve convenient to adjust with the authorization announcement number CN214146673U, it includes a valve body. A valve core is arranged inside the valve body. A valve seat is arranged at the lower end of the valve body. A valve cover is arranged at the upper end of the valve body. An installation plate is arranged on the outer surface of the lower end of the valve seat. Fastening bolts are arranged inside the installation plate. A connecting rod is arranged on one side of the valve body. A turntable is arranged on the outer surface of one end of the connecting rod. After adopting the above technical solution, the beneficial effect of the utility model is that the sleeve drives the packing moving part to slide up and down, which is convenient to adjust the flow rate of the valve body, and the operation is convenient.

[0004] Although the above patent is convenient to adjust the flow rate of the valve body and the operation is convenient, the use of two bevel gears for transmission may have a rotation situation, and when the bevel gears are worn and replaced, they need to be disassembled together with the valve stem, which is extremely inconvenient during maintenance. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hard-sealed V-ball valve which is convenient to adjust, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A hard-sealed V-ball valve which is convenient to adjust, including

[0008] A ball valve body, flanges are integrally formed at both ends of the ball valve body. A valve stem is arranged at the upper end inside the ball valve body. A V-shaped sphere is arranged at the bottom end of the valve stem;

[0009] A high platform, which is integrally formed at the upper middle part of the ball valve body. The top of the high platform is fixedly installed with a valve cover through bolts. A connecting mechanism is arranged inside the valve cover and the high platform;

[0010] A transmission shell, which is arranged at the middle part of the top of the valve cover. A driving mechanism is arranged inside the transmission shell.

[0011] Preferably, the connecting mechanism includes a transmission shaft movably installed in the middle of the inner side of the valve cover. A fixed disk is fixedly installed at the bottom end of the transmission shaft. A movable disk is movably installed at the upper middle part of the high platform. Card slots are symmetrically arranged on both sides of the top end of the movable disk. Clamping blocks matching the card slots are symmetrically arranged on both sides of the bottom end of the fixed disk;

[0012] Preferably, the connecting mechanism further includes a fixed rod arranged at the middle of the bottom end of the movable disk. A connecting piece for clamping with the valve rod is arranged at the bottom end of the fixed rod. The fixed rod and the valve rod are movably connected by a spring outside the connecting piece;

[0013] Preferably, the driving mechanism includes a worm gear movably installed at the upper end of the inside of the transmission housing. The top end of the transmission shaft is fixedly connected to the worm gear. A worm meshing with the worm gear is arranged inside one side of the transmission housing. One end of the worm passes through the transmission housing and is fixedly installed with a hand wheel;

[0014] Preferably, a pointer is fixedly installed at the top end of the worm gear passing through the transmission housing;

[0015] Preferably, hard seals are arranged on both sides of the inner wall of the ball valve body.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. For this easy-to-adjust hard-sealed V-type ball valve, through the cooperation of the fixed disk, movable disk, fixed rod, connecting piece and valve rod, when it is necessary to disassemble and replace the worm gear or worm, remove the bolts between the valve cover and the outside of the high platform, and then remove the valve cover from the top of the high platform. In this way, when disassembling and repairing, there is no need to take out the valve rod inside the ball valve body. On the contrary, when installing, just snap the clamping blocks on both sides of the bottom end of the fixed disk into the card slots at the top end of the movable disk to quickly connect, so as to achieve the purpose of easy and quick repair.

[0018] 2. For this easy-to-adjust hard-sealed V-type ball valve, through the cooperation of the worm gear, worm, hand wheel and pointer, when adjusting, rotate the hand wheel. The hand wheel drives the worm to rotate. The worm drives the worm gear to rotate. The worm gear drives the fixed disk to rotate through the transmission shaft. The fixed disk drives the movable disk to rotate through the clamping blocks. The movable disk drives the valve rod to rotate through the fixed rod and the connecting piece. The valve rod drives the V-type ball to rotate, and thus the angle of the V-type ball can be adjusted. And by observing the pointer, the opening and closing degree of the V-type ball can be intuitively understood, so as to achieve the purpose of easy adjustment. BRIEF DESCRIPTION OF THE DRAWINGS
