[0002] A pressure reducing valve is a valve that reduces the inlet pressure to a required outlet pressure through adjustment and relies on the energy of the medium itself to automatically maintain the outlet pressure stable. From the perspective of fluid mechanics, a pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, so as to achieve the purpose of pressure reduction.
[0003] When the existing pressure reducing valve for a water tank inlet valve belt is installed and used, it cannot be connected to inlet valve belts with different diameters, and the internal structure of the device is complex, and the manufacturing cost is relatively high. At the same time, although a silica gel ring is provided in the existing pressure reducing valve, the sizes of the inlet valve belt and the anti-leakage rubber ring are not adapted, that is, there are gaps between the inlet valve belt, the anti-leakage rubber ring and the pressure reducing valve body, which will also cause water leakage, bringing certain adverse effects to the use process of people. In order to solve the deficiencies of the existing technology, we propose a pressure reducing valve for a water tank inlet valve belt. Content of the Utility Model

Specific embodiments
[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] As Figure 1 shown, a connecting pipe 2 is welded to the upper end of the vertical pipe 1, an assembled pipe 11 is welded to the upper end of the connecting pipe 2, a limit ring 9 is threadedly connected to the outer wall of the assembled pipe 11, a connecting ear plate 10 is welded to the outer wall of the limit ring 9, a horizontal pipe 3 is welded to the outer wall of the vertical pipe 1, and a collar 5 is arranged on the right side of the horizontal pipe 3.
[0023] As Figure 2 shown, a fixed ring 6 is welded inside the vertical pipe 1, an installation groove is arranged inside the fixed ring 6, the first anti-leakage rubber ring 7 is detachably connected to the fixed ring 6 through the installation groove, a convex ring 16 is welded to the right side of the horizontal pipe 3, and the diameter of the convex ring 16 is larger than that of the horizontal pipe 3. The spherical plug 14 is sequentially passed through the convex ring 16 and the horizontal pipe 3 and then located inside the vertical pipe 1. The spherical plug 14 is used to change the space of the internal channel of the vertical pipe 1.
[0024] As Figure 3 shown, the diameter of the first threaded rod 8 is larger than that of the second threaded rod 15. The second anti-leakage rubber ring 13 is sleeved on the outer wall of the second threaded rod 15, and the end face is abutted by the first threaded rod 8. A collar 5 is arranged on the outer wall of the first threaded rod 8, a rotating handle 4 is welded to the outer wall of the collar 5, and the outer corner of the rotating handle 4 is rounded.
[0025] As Figure 4 shown, a threaded pipe 12 is welded to the lower end of the vertical pipe 1, an assembled pipe 11 is welded to the upper end of the connecting pipe 2, threads are arranged on the outer wall of the assembled pipe 11, and the material of the assembled pipe 11 is elastic steel, which can be elastically deformed to a certain extent. The limit ring 9 and the assembled pipe 11 are threadedly connected.
[0026] It should be noted that the present utility model is a water tank inlet valve with a pressure reducing valve. When in use, the user sleevs the limit ring 9 on the outer wall of the belt port pipe of the inlet valve belt, and then sleevs the belt port pipe into the vertical pipe 1 so that the pipe end face abuts against the fixed ring 6. Rotate the limit ring 9 downward and connect the limit ring 9 and the assembly pipe 11 until the limit ring 9 is rotated downward again and the assembly pipe 11 is buckled by the limit ring 9, and the pipe orifice of the assembly pipe 11 contracts inward, so that the assembly pipe 11 can fixedly clamp the belt port pipe. At the same time, the pipe end face tightly abuts against the surface of the first anti-leakage rubber ring 7 to prevent the device from leaking when water enters.
[0027] By rotating the rotating handle 4, the first threaded rod 8 is driven to rotate in the convex ring 16, and the second threaded rod 15 is driven to rotate in the horizontal pipe 3, so as to change the position of the spherical plug 14 inside the vertical pipe 1. At the same time, a second anti-leakage rubber ring 13 is arranged at the connection of the first threaded rod 8 and the second threaded rod 15 to prevent water leakage. When the spherical plug 14 can dynamically change the internal channel space of the vertical pipe 1, the function of adjusting the water pressure inside the vertical pipe 1 can be realized.
