Abstract
Description
Technical Field
[0001] The utility model belongs to the field of valves, in particular to an adjustable 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 the outlet pressure stable 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, and then relying on the regulation of the control and regulation system to balance the fluctuation of the pressure behind the valve with the spring force, so that the pressure behind the valve remains constant within a certain error range.
[0003] When water first enters the pressure reducing valve, the impact force of the water will cause the pressure reducing valve to vibrate. In the long run, this will cause the pressure reducing valve and the connection to loosen, affecting the stability of the connection. In addition, the pressure reducing valve is mostly installed and fixed when connected to an external pipeline. When connecting to external pipelines set at different heights, the installation height cannot be adjusted. Support and fixing structures of different specifications are required for installation, which has poor practicality. Utility Model Content

[0022] like Figure 1 and Figure 3 As shown, there are two groups of the mounting base plate 2, the adjusting mechanism 3 and the mounting mechanism 5, and the mounting base plate 2, the adjusting mechanism 3 and the mounting mechanism 5 are respectively arranged on both sides of the valve body 1, and the mounting base plate 2 is threadedly connected with a second bolt 201 for installing and fixing the mounting base plate 2.
[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the adjustment mechanism 3 also includes a limiting guide column 304, the lower end of the screw rod 302 is rotatably connected to the upper part of the mounting base plate 2, the screw rod 302 and the connecting plate 301 are through-connected, a turntable 303 is fixedly provided at the upper end of the screw rod 302 for controlling the movement of the connecting plate 301, the lower end of the limiting guide column 304 is fixedly connected to the upper part of the mounting base plate 2, the middle section of the limiting guide column 304 is slidably connected to the connecting plate 301 and penetrates the connecting plate 301, and a limiting block 305 is fixedly provided at the upper end of the limiting guide column 304 for limiting the moving direction and position of the connecting plate 301.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the mounting mechanism 5 includes an upper mounting frame 501 and a lower mounting frame 502, the upper mounting frame 501 is set to a semicircular ring structure, the upper part of the lower mounting frame 502 is set to a semicircular ring structure, the upper mounting frame 501 and the lower mounting frame 502 are connected by a third bolt 503, and pillars 504 are fixed on both sides of the lower part of the third bolt 503. The shock absorbing assembly 4 is provided with 4 groups of shock absorbing assemblies, and the shock absorbing assembly 4 includes a spring 401 and a damper 402.

In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
