Description
Technical Field
[0001] The present application relates to the technical field of pipeline performance detection, and in particular to a pressure-stabilizing water tank. Background Art
[0002] The hydrostatic test is used to determine the pressure-resistant failure time or the maximum pressure value of instantaneous explosion of various pipes under long-term constant internal pressure and constant temperature.

DETAILED DESCRIPTION
[0032] The present application is further described in detail below in conjunction with the accompanying drawings.
[0033] The present application embodiment discloses a pressure stabilizing water tank. Figure 1 , Figure 2 and Figure 3The pressure-stabilizing water tank is arranged on one side of the main pump 2. The pressure-stabilizing water tank 1 includes a water tank 1 and a water level regulating assembly arranged in the water tank 1. The height direction of the water tank 1 is arranged vertically. A water inlet 11 is provided on the side wall of the water tank 1 near the top. The water inlet 11 is connected to the tap water pipe 3. A water outlet 12 is provided on the side wall of the middle part of the water tank 1. The water outlet 12 is connected to the main pump 2. The water level regulating assembly includes a water inlet box 4, a movable rod 5, a hollow float 7 and a blocking member.
[0034] Reference Figure 3 The water inlet box 4 is fixedly connected to the inner wall of the water tank 1 and is located on one side of the water inlet 11; the two ends of the water inlet box 4 are respectively provided with a water inlet 41 and a drain 42, the water inlet 41 is connected to the water inlet 11, and the drain 42 faces downward, so that the water in the tap water pipe 3 can flow into the water tank 1 through the water inlet box 4. The movable rod 5 is hinged on the inner wall of the water tank 1, the hinge axis of the movable rod 5 is arranged along the length direction of the water tank 1, and the hinge axis of the movable rod 5 is located on the side close to the water inlet box 4. The hollow float 7 is a hollow shell structure, so it is subject to greater buoyancy in water and will float on the surface of the water. The hollow float 7 is fixedly connected to the end of the movable rod 5 away from its own hinge axis. The blocking member is a conical block, which is fixedly connected to the end of the movable rod 5 close to its own hinge axis, and can block the drain 42 of the water inlet box 4.
[0035] During operation, the water pipe 3 is opened, and the water in the water pipe 3 flows into the water inlet box 4, and then flows into the water tank 1 through the drain port 42. As the water flows in, the water level in the water tank 1 gradually rises, and the hollow float 7 always floats on the surface of the water. Therefore, the rising water level will cause the hollow float 7 to move up, and the hollow float 7 drives the movable rod 5 to rotate upward; when the water level reaches the height of the water outlet 12 of the water tank 1, the water in the water tank 1 flows into the main pump 2, and continuously supplies water to the main pump 2; when the water level in the water tank 1 continues to rise, the water stop block 6 will gradually block the drain port 42 of the water inlet box 4, thereby reducing the water entering the water tank 1 and preventing the water level from continuing to rise.
[0036] Therefore, when the water level in the water tank 1 is low, the tap water pipe 3 continuously injects water into the water tank 1; when the water level in the water tank 1 is high, the water stop block 6 blocks the drain port 42, thereby reducing the inflow of water, so that the water level in the water tank 1 can be maintained in a relatively stable state, so that while supplying water to the main pump 2, the water pressure in the tap water pipe 3 can be unloaded into the water tank 1, thereby reducing the influence of the water pressure on the main pump 2 and the solenoid valve.
[0037] Among them, refer to Figure 3, the movable rod 5 includes a first connecting rod 51, a second connecting rod 52 and a locking member. One end of the first connecting rod 51 is hinged on the inner wall of the water tank 1, and the water stop block 6 is fixedly connected to the first connecting rod 51; the second connecting rod 52 is located at the end of the first connecting rod 51 away from the water inlet box 4, and the hollow float 7 is fixedly connected to the end of the second connecting rod 52; the first connecting rod 51 and the second connecting rod 52 are both provided with connecting holes at the ends close to each other, and the connecting holes on the first connecting rod 51 and the second connecting rod 52 are coaxially arranged. The locking member includes a locking bolt 53 and a locking nut 54, the locking bolt 53 is inserted into the connecting hole, and the locking nut 54 is threadedly connected to the locking bolt 53, so that the first connecting rod 51 and the second connecting rod 52 are fixedly connected together. Therefore, after the locking nut 54 is unscrewed, the angle between the first connecting rod 51 and the second connecting rod 52 can be adjusted, and the position of the hollow float 7 can be adjusted, so as to adjust the highest water level in the water tank 1, which is suitable for more practical needs.
[0038] A buffer chamber 43 is provided inside the water inlet box 4. The buffer chamber 43 is arranged along the length direction of the water inlet box 4. The two ends of the buffer chamber 43 are respectively connected with the water inlet 41 and the drain outlet 42; the inner wall diameters at the two ends of the buffer chamber 43 are larger, and the inner wall diameter in the middle of the buffer chamber 43 is smaller. Therefore, when the water in the tap water pipe 3 flows into the water inlet box 4, the buffer chamber 43 can buffer the water flow, thereby reducing the pressure of the water flow on the water stop block 6, and ensuring the water stopping effect of the water stop block 6.
[0039] The water stop block 6 is arranged in a cone shape, and a conical structure matching the water stop block 6 is arranged at the drain outlet 42, thereby enhancing the sealing performance; a rubber pad 61 is bonded to the outer wall of the water stop block 6, which can further enhance the water stopping effect and prevent the water level from continuing to rise.
[0040] Since the water outlet 12 is located in the middle of the water tank 1, impurities and other sediments in the water will sink to the bottom of the water tank 1 and are not easily discharged into the main pump 2 through the water outlet 12. Figure 4 A sedimentation box 8 is placed in the water tank 1. The sedimentation box 8 is located at the bottom of the water tank 1. There are multiple sedimentation boxes 8 arranged in an array and abutting against each other. A grid frame 81 is provided in the sedimentation box 8, so that the sedimentation box 8 is convenient for collecting sediment in the water. The sedimentation box 8 can be taken out regularly to remove the sediment such as scale in the water tank 1, thereby ensuring the quality of the water entering the main pump 2.
[0041] The implementation principle of a pressure-stabilizing water tank in the embodiment of the present application is as follows: the water in the tap water pipe 3 first enters the water tank 1 through the water inlet box 4, and when the water level in the water tank 1 rises, the water in the water tank 1 flows into the main pump 2; after the water level in the water tank 1 rises, the hollow float 7 rises, the hollow float 7 drives the movable rod 5 to rotate, and the movable rod 5 drives the water stop block 6 to rotate, and when the water stop block 6 rotates to the drain port 42 of the water inlet box 4, the water stop block 6 blocks the drain port 42, and the tap water pipe 3 stops filling with water; then, under the action of the water outlet 12 of the water tank 1, the water level gradually decreases, so that the water stop block 6 moves to the side away from the drain port 42, and then the tap water pipe 3 continues to fill with water until the water level in the water tank 1 reaches a dynamic balance. At this time, the water entering the main pump 2 is less affected by the water pressure because it flows in from the water tank 1 by itself, which helps to ensure the normal operation of the main pump 2 and the solenoid valve.
[0042] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
