Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing valves, in particular to a fatigue-resistant and impact-resistant pressure reducing valve. Background Art

[0002] The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through regulation, and automatically maintains a stable outlet pressure by relying on the energy of the medium itself. From the perspective of fluid mechanics, the pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of reducing pressure. Then, by relying on the regulation of the control and regulation system, the fluctuation of the pressure behind the valve is balanced with the spring force, so that the pressure behind the valve remains constant within a certain error range.

[0003] During the operation of the pressure reducing valve, the water inlet part will be subjected to a large impact force, which mainly needs to be borne by the pressure reducing valve itself and the connections at both ends of the pressure reducing valve. Long-term operation will cause the pressure reducing valve to have safety hazards due to problems such as impact fatigue.

[0004] To this end, this solution proposes an anti-fatigue and impact-resistant pressure reducing valve to solve the above problems. Utility Model Content

[0020] Reference Figure 1-Figure 3 , a fatigue-resistant and impact-resistant pressure reducing valve comprises a valve body 1, a switch handle 2 is provided at one end of the valve body 1, mounting joints 3 are provided at both ends of the valve body 1, mounting rings 4 are rotatably connected to the two mounting joints 3, a plurality of mounting holes 5 are provided on the two mounting rings 4 which are centrally symmetrically arranged, connecting rings 6 are provided on the inner walls of the two mounting rings 4, annular grooves 7 are provided on the side walls of the two connecting rings 6 close to the two mounting joints 3, annular blocks 8 are rotatably connected in the two annular grooves 7, the cross-sections of the two annular grooves 7 are T-shaped, the cross-sections of the two annular blocks 8 are also T-shaped, the two annular blocks 8 are matched with the two annular grooves 7 respectively, so that the connection is tighter and there will be no separation problem, the two annular blocks 8 are respectively fixedly connected to the two mounting joints 3, so that the mounting ring 4 can be stably rotated, and then can be installed during the installation work In order to adjust the mounting ring 4 to be larger, the mounting holes 5 can be aligned, and the placement angle of the valve body 1 is prevented from affecting the installation of the mounting ring 4. A working disk 9 is provided on the outer wall of the side of the valve body 1 away from the switch handle 2. A threaded sleeve 14 is rotatably connected to the working disk 9 on the side wall away from the valve body 1. A rotating groove 17 is provided on the side wall of the working disk 9 close to the threaded sleeve 14. A rotating block 18 is rotatably connected in the rotating groove 17. The rotating block 18 is fixedly connected to the threaded sleeve 14. The rotating groove 17 and the rotating block 18 are arranged in a concave-convex matching manner. Such a connection makes it impossible for the threaded sleeve 14 to separate from the working disk 9 and can rotate stably. A threaded seat 15 is connected to the inner thread of the threaded sleeve 14. A support disk 16 is fixedly connected to the threaded seat 15 on the side wall away from the threaded sleeve 14. In this way, the valve body 1 can be stably placed with the help of the working disk 9, which facilitates assembly work.

[0021] A plurality of spikes 19 are fixedly connected to a side wall of the support plate 16 away from the threaded sleeve 14, so that the support plate 16 can be placed on the ground more stably, further ensuring the stability and safety of the valve body 1.
