[0021] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-Figure 4 The utility model provides a technical solution: a temperature reducing and pressure reducing device with a flow monitoring function, the temperature reducing and pressure reducing device with a flow monitoring function comprises: a valve body 1, a mounting plate 2 is arranged on the surface of the valve body 1, a positioning screw tube 3 is arranged on the surface of the mounting plate 2, a flow monitoring device 4 can be inserted into the mounting plate 2, a threaded column 5 is sleeved on the surface of the flow monitoring device 4, and a positioning nut 6 is screwed on the surface of the threaded column 5; a support plate 7, a damping bearing 8 is arranged on the surface of the support plate 7, a support rod 9 is inserted into the damping bearing 8, and a limit plate 10 is arranged at one end of the support rod 9;

[0024] First, the flow monitoring device 4 can be fixed on the valve body 1 by using the positioning nut 6 in cooperation with the mounting plate 2, and the threaded tube 16 set at the bottom of the positioning nut 6 is engaged with the positioning screw tube 3 to improve the stability of the fixation of the flow monitoring device 4, so that the staff can monitor the internal flow of the valve body 1 in real time and record the data conveniently.

[0025] Embodiment 2

[0026] On the basis of the first embodiment, in order to prevent the positioning nut 6 from loosening due to the vibration generated by the operation of the valve body 1, a limit plate 10 is provided, one end of the support plate 7 is fixedly connected to the side of the mounting plate 2, the support plate 7 is a square plate structure, the damping bearing 8 is fixedly connected to the surface of the support plate 7, the support rod 9 is fixedly connected to the inner ring surface of the damping bearing 8, and the limit plate 10 can limit the upper surface of the positioning nut 6;

[0027] When in use, after the flow monitoring device 4 is fixed with the positioning nut 6, the support rod 9 can be rotated so that the support rod 9 cooperates with the damping bearing 8 to rotate the limit plate 10, and the limit plate 10 can be used to resist the upper surface of the positioning nut 6, thereby avoiding the problem that the positioning nut 6 may become loose due to the vibration of the valve body 1 during long-term operation. The setting of the damping bearing 8 also avoids the problem of the support rod 9 rotating at will.

[0028] Embodiment 3
