Description

Technical Field

[0001] This utility model relates to the field of water tightness test technology, specifically a portable municipal unpressurized pipeline water tightness test water replenishment device. Background Technology

[0002] In urban infrastructure construction, drainage pipe networks serve as a core component for addressing urban flooding, improving sewage collection efficiency, promoting rainwater and sewage separation, and building sponge cities. The quality of these systems directly impacts the effectiveness of urban water environment management and ecological functions. Therefore, whether it's the acceptance process for newly constructed drainage pipes or the implementation of trenchless repair techniques for structurally defective pipes, a comprehensive quality control system must be established to ensure the stable operation of the drainage pipe network system.

[0003] Currently, there is no portable, continuously replenishing water device available on the market for municipal pressureless pipeline water tightness testing. In municipal pressureless pipeline water tightness testing, the amount of water replenished by manually pouring water is used to measure the amount of water leaking from the pipeline. However, manual pouring of water introduces errors and cannot provide continuous water replenishment, thus failing to guarantee the stability of the water head inside the pipeline. Utility Model Content

[0004] The purpose of this invention is to provide a portable municipal unpressurized pipeline water tightness test water replenishment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable municipal pressureless pipeline water tightness test water replenishment device, comprising a well ring, a turbine flow meter, and a stop valve. A pipe is provided on one side of the well ring. An explosion-proof water pipe is connected to the left side of the stop valve. A universal adapter is connected to the right end of the stop valve. Universal adapters are connected to both sides of the turbine flow meter. A nipple connector is connected to one side of the universal adapter. A water outlet pipe is connected to one side of the turbine flow meter. A water pump is fixedly connected to one side of the water outlet pipe. A water inlet pipe is connected to the right side of the water pump. A water storage tank is movably connected to the water inlet pipe.

[0006] Preferably, the surface of the turbine flow meter is provided with a display, and the display is made of LED display screen.

[0007] Preferably, the top of the water stop valve is provided with a movable handle, and the surface of the movable handle is provided with anti-slip texture.

[0008] Preferably, the surface of the explosion-proof water pipe is provided with a reinforcing layer, and the reinforcing layer is made of fiber woven mesh.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention connects an explosion-proof water pipe, a stop valve, a universal adapter, a turbine flow meter, a nipple connector, an outlet pipe, a water pump, and an inlet pipe. The inlet pipe is placed inside the water storage tank. The stop valve is closed, and the water pump and turbine flow meter are turned on to begin operation. After the turbine flow meter displays the numbers, the stop valve is opened. The water flow is adjusted to the required test head according to the amount of water replenished in the pipeline. The stop valve is used to maintain a balance between the water flow rate and the leakage rate. The cumulative flow rate in the turbine flow meter allows for convenient and accurate reading of the leakage rate during the pipeline water tightness test. Continuous water replenishment ensures a stable test head, avoids errors associated with manual water pouring, and improves the accuracy and reliability of the water tightness test.
