Description

Technical Field

[0001] The utility model relates to the field of water pressure detection equipment, in particular to a water supply pressure detection device for a water plant. Background Art

[0002] With the increase in the number of urban residents in today's society, the demand for tap water for daily life is increasing. Therefore, the amount of tap water that needs to be transported by water plants is also gradually increasing. The water plants adopt the pressurized transportation method, which transports water to each resident's residence by applying uniform pressure. However, the pressure required to be applied to different residential buildings is different, and sometimes the difference may be very large. If the tap water is transported without being detected in time, it will cause damage to the water pipes.

[0003] However, most of the existing pressure detection devices are fixed on the water pipes and cannot be disassembled. If the pressure detection device is damaged, it is inconvenient to replace it, which greatly increases the cost of use and maintenance. In this regard, in order to solve this technical problem, the present application proposes a water supply pressure detection device for a water plant. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] Reference Figure 1-4 The utility model provides an embodiment: a water supply pressure detection device for a waterworks, comprising a water supply pipe 1, a branch pipe 2 is fixedly connected to the middle end of the top side of the water supply pipe 1, the branch pipe 2 facilitates the installation and disassembly of a pressure detection gauge 8, a pressure detection gauge 8 is arranged on the top side of the branch pipe 2, the pressure detection gauge 8 can detect the water pressure of the water supply pipe 1, a pipe sleeve 6 is fixedly connected to the bottom side of the pressure detection gauge 8, the pipe sleeve 6 can cover the branch pipe 2, both ends of the bottom side of the pipe sleeve 6 are rotatably connected with a rotating rod 11, the outer wall of the rotating rod 11 is rotatably connected with a connecting rod 7, the connecting rod 7 can fix the pipe sleeve 6 and the branch pipe 2, a clamping block 10 is fixedly connected to the bottom side of the connecting rod 7, the fixing ring 4 is moved to engage with the clamping block 10, so as to fix the position of the connecting rod 7, and the connecting rod 7 is prevented from rotating, thereby preventing the pressure detection gauge 8 from falling off, a fixing block 9 is arranged on the outer wall of the middle end of the connecting rod 7, a fixing ring 4 is arranged on the outer wall of the bottom side of the branch pipe 2, and a soft metal gasket 13 is arranged inside the pipe sleeve 6.

[0024] The fixing block 9 is located on the outer wall of the middle end of the connecting rod 7, and a sliding groove is provided on the side of the connecting rod 7 close to the fixing block 9. The fixing block 9 is slidably connected in the sliding groove. When the fixing block 9 is not engaged with the fixing ring 2 5, due to the contraction force of the spring 12, the fixing block 9 is located on the top side of the sliding groove. When the fixing block 9 is engaged with the fixing ring 2 5, the fixing block 9 will stretch the spring 12. At the same time, due to the contraction force of the spring 12, the fixing block 9 will engage the fixing ring 2 5 more firmly. A spring 12 is provided on the side of the fixing block 9 close to the rotating rod 11. One end of the spring 12 is connected to the connecting rod 7, and the other end of the spring 12 is connected to the fixing block 9. A fixing ring 4 is located on the outer wall of the bottom side of the branch pipe 2, and the outer wall of the branch pipe 2 is provided with two grooves, and moving blocks are slidably connected in the two grooves. The other ends of the two moving blocks are fixedly connected to the inner circumference of the fixing ring 4, and the shape of the groove is an inverted L-shape. When it is necessary to lock the block 10, the moving block can be moved from the horizontal groove to the vertical groove, and then the moving block is moved downward, so that the fixing ring 4 is stuck between the block 10 and the connecting rod 7, thereby fixing the connecting rod 7. The soft metal gasket 13 located inside the pipe sleeve 6 can fill some small uneven areas inside the pipe sleeve 6. At the same time, the elastic deformation of the soft metal gasket 13 itself can adapt to different surface shapes to ensure good sealing performance. A circular groove is provided on the inner wall of the top side of the pipe sleeve 6. A rubber gasket 14 is provided on the bottom side of the soft metal gasket 13. The rubber gasket 14 can maintain sealing performance while bearing the water flow pressure, and reduce the friction and wear between the soft metal gasket 13 and the branch pipe 2, which helps to extend the service life of the soft metal gasket 13 and the branch pipe 2, and reduce the maintenance and replacement costs. The soft metal gasket 13 and the rubber gasket 14 are both located in the circular groove. The clamping block 10 fits the outer wall of the branch pipe 2, and a certain fixing ring 4 is clamped between the clamping block 10 and the connecting rod 7 to limit the movement of the connecting rod 7, thereby preventing the connecting rod 7 from rotating, thereby causing the pressure detection gauge 8 to fall off. The top outer wall of the branch pipe 2 is fixedly connected with a fixing ring 2 5, and the bottom side of the fixing ring 2 5 is engaged with the fixing block 9, and the pipe sleeve 6 and the branch pipe 2 can be fixed together by engaging the fixing ring 2 5 with the fixing block 9. A valve 3 is provided at the rear side of the branch pipe 2, and the valve 3 can be closed before installing the pressure detection gauge 8, and the valve 3 can be opened after the installation is completed.

[0025] Working principle: First, the staff engages the pipe sleeve 6 with the branch pipe 2, and engages the fixing block 9 with the fixing ring 2 5 by rotating the connecting rod 7. The spring 12 strengthens the engagement effect of the fixing block 9 and the fixing ring 2 5, thereby improving the firmness of the connection between the pipe sleeve 6 and the branch pipe 2. When the fixing block 9 and the fixing ring 2 5 are engaged, the clamping block 10 also fits the outer wall of the branch pipe 2, rotates the fixing ring 1 4, and then moves the fixing ring 1 4 downward and clamps it between the clamping block 10 and the connecting rod 7, thereby fixing the connecting rod 7 to prevent the connecting rod 7 from rotating, thereby causing the pressure detection gauge 8 to fall off. After the installation is completed, the valve 3 can be opened to complete the pressure detection of the water supply pipe 1. At the same time, the soft metal gasket 13 and the rubber gasket 14 in the pipe sleeve 6 can improve the airtightness of the contact between the pipe sleeve 6 and the branch pipe 2 to avoid air leakage at the connection, which may cause the detection result to be inaccurate.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
