Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a guide structure for valves. Background Art

[0002] Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media. Valves are also categorized by material into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and non-standard custom valves.

[0003] Existing tee pipes require adjusting two valves to guide the water flow when opening and closing the drain outlet, which is very inconvenient. Furthermore, existing valves usually rely on only one valve stem for opening and closing, which can easily lead to loose seals and leakage due to uneven force on all sides. To address this technical problem, this application proposes a guide structure for a valve. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a guide structure for a valve, which aims to improve the existing three-way pipe, which is very troublesome in opening and closing two valves when adjusting the flow direction of water, and the valve is prone to leakage due to uneven force on all sides, resulting in loose sealing.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A guide structure for a valve comprises a tee, wherein two valve stems are rotatably connected inside the tee, and the outer walls of the valve stems are fixedly connected to the valves, the top of the valve stem on the right side is connected to the valve stem on the left side through a transmission assembly, the top of the outer wall of the tee is fixedly connected to a connecting shell, and the right side of the top of the connecting shell is connected to the top of the right valve stem through a switch assembly, and two sliding grooves are provided on the left and right sides of the inner wall of the tee, the inner walls of the sliding grooves are rotatably connected to threaded rods, the inner walls of the sliding grooves are slidably connected to sliders, the outer walls of the threaded rods are threadedly connected to the bottom sides of the outer walls of the sliders, and the tops of the sliders are fixedly connected to magnetic protection rings, and the proximal ends of the two threaded rods are connected to the bottom ends of the valve stems through meshing assemblies.

[0007] Furthermore, the transmission assembly includes a first pulley fixedly connected to the top end of the right valve stem, and a second pulley fixedly connected to the top end of the left valve stem. The top and bottom ends of the second pulley and the top and bottom ends of the valve stem are rotatably connected to the inner wall of the connecting shell.

[0008] Furthermore, the second pulley and the first pulley are connected via a belt strip.

[0009] Furthermore, the switch assembly includes a switch column fixedly connected to the right side of the top end of the connecting shell, the inner wall of the switch column is slidably connected to the switch block, the inner wall of the switch column is rotatably connected to the spiral rod, the outer wall of the spiral rod is threadedly connected to the left side of the switch block, and the bottom end of the spiral rod is fixedly connected to the top end of the right valve stem.

[0010] Furthermore, the meshing assembly includes a first bevel gear fixedly connected to the bottom end of the valve stem, and the two threaded rods are fixedly connected to the adjacent ends thereof with a second bevel gear, and the outer wall of the second bevel gear is meshed with the outer wall of the first bevel gear.

[0011] Furthermore, a handle is fixedly connected to the right side of the switch block, and an outer wall of the handle is provided with anti-slip stripes.

[0012] Furthermore, sealing gaskets are provided on adjacent sides of the two magnetic protection rings.

[0013] The utility model has the following beneficial effects:

[0014] In this utility model, by grasping the handle and sliding the switch block, the spiral rod rotates, which in turn rotates the valve stem, opening and closing the valve. Simultaneously, the right valve stem rotates the first pulley, which, through the belt, rotates the second pulley. The second pulley rotates the left valve stem. Rotating the left valve stem opens and closes the left valve. Closing one valve opens the other, eliminating the need to manually close both valves and improving work efficiency.

[0015] 2. In this utility model, the valve stem rotates, driving the first bevel gear, which in turn drives the second bevel gear, which in turn drives the threaded rod to slide along the inner wall of the tee, bringing the two magnetic protection rings closer together. The magnetic attraction between the two magnetic protection rings clamps the valve, thereby preventing leakage caused by uneven force on all sides of the valve. BRIEF DESCRIPTION OF THE DRAWINGS
