[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides as Figures 1-4A water supply pipe network pressure monitoring device shown in the figure includes a connecting pipe 1. A flange 4 is fixedly connected to the bottom end of the connecting pipe 1. The device also includes a measuring component, a fixing component and a loosening prevention component.

[0023] Specifically, the measuring component is arranged at the top end of the connecting pipe 1. The measuring component includes a pressure gauge 2 arranged at the top of the connecting pipe 1. A blocking part is arranged at the connection between the connecting pipe 1 and the pressure gauge 2.

[0024] It should be noted that the blocking part includes a ball valve 3. The water inlet end of the ball valve 3 is fixedly connected to the top of the connecting pipe 1, and the connection method is threaded connection. The water outlet end of the ball valve 3 is fixedly connected to the water inlet end of the pressure gauge 2, and the connection method is threaded connection.

[0025] Specifically, the fixing component is arranged at the top of the flange 4. The fixing component includes a plurality of fixing bolts 6 inserted through the top of the flange 4. The plurality of fixing bolts 6 are used to penetrate the threaded holes of the pipe network interface.

[0026] It should be noted that the pipe network interface is set in the form of flange connection. The threaded holes arranged on the flange connection side are used for the threaded penetration and fixation of the fixing bolts 6.

[0027] Specifically, the loosening prevention component is used to prevent the fixing bolts 6 from loosening. The loosening prevention component includes a fixing sleeve 5 arranged at the top of the flange 4. A resilient part is arranged on the outer side of the fixing bolt 6 and inside the inner cavity of the fixing sleeve 5.

[0028] It should be noted that the fixing sleeve 5 and the flange 4 are fixed by welding. The outer wall of the fixing sleeve 5 is set to be cylindrical. A water isolation ring 401 is arranged at the bottom of the flange 4 to prevent seepage at the interface of the flange 4. A buffer ring 402 is arranged at the bottom of the flange 4 and outside the water isolation ring 401. The water isolation ring 401 and the buffer ring 402 are made of rubber material, and both are adhesively bonded to the flange 4. The water isolation ring 401 can prevent the water seepage at the water inlet end of the connecting pipe 1 from entering the outside of the bottom of the flange 4 and corroding the fixing bolts 6.

[0029] Specifically, the resilient part prevents the fixing bolts 6 from loosening by providing a pre-tightening force for the fixing bolts 6.
