The method for sealing the pipeline openings in conventional water supply and drainage pipeline water-tightness tests is as follows: baffles are set in the inspection wells on both sides of the starting point and the end point of the test pipe section to temporarily block the pipeline. The baffles are made of wood or steel plates with a diameter larger than the pipeline. The selected baffles should ensure that the bearing capacity is greater than the combined force of the water pressure; a combined wooden support or a jack is set in the inspection well to firmly press the baffle; in order to prevent water seepage from the baffle, rubber water-stop gaskets, waterproof sealants, etc. are set between the baffle and the pipeline.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Figure 1-Figure 5 As shown, the utility model provides a water-tightness test device for water supply and drainage pipelines, comprising: a test tank 1, the outer surface of the test tank 1 is fixedly connected to a mounting block 4, the inner surface of the mounting block 4 is provided with a pipeline body 10, and a storage assembly 2 is provided on the top of the test tank 1; a storage assembly 2, the storage assembly 2 comprises a storage tank 201, a pump body 202 is provided on the top of the storage tank 201, the output end of the pump body 202 is fixedly connected to a first pipe body 203, the input end of the pump body 202 is fixedly connected to a second pipe body 204, the end face of the second pipe body 204 is fixedly connected to a fixed pipe 207, the outer surface of the fixed pipe 207 is fixedly connected to a mounting column 206, and the outer surface of the mounting column 206 A first airbag 205 is provided on the surface, an annular groove 9 is provided on the inner surface of the mounting block 4, a second airbag 6 is provided on the inner surface of the annular groove 9, the inner surface of the second airbag 6 is fitted with the outer surface of the pipe body 10, the outer surface of the first airbag 205 is fitted with the inner surface of the pipe body 10, the outer surface of the test tank 1 near the top is fixedly connected with a water inlet pipe 5, the water inlet pipe 5 is L-shaped, the first tube body 203 extends vertically downward to the interior of the storage tank 201, the outer surface of the pipe body 10 is fitted with the inner surface of the mounting block 4, the outer surface of the test tank 1 away from the mounting block 4 is fixedly connected with a U-shaped tube 7, and the outer surface of the U-shaped tube 7 is provided with multiple scale lines 8 at equal intervals.

[0024] The effect achieved by the entire embodiment 1 is that, during the water-water closed test of the water supply and drainage pipeline, one end of the pipeline body 10 to be tested is placed inside the mounting block 4 so that it is connected to the test tank 1, and after the first airbag 205 is placed from the other end of the pipeline body 10 to be tested, the first airbag 205 and the second airbag 6 are inflated in sequence using an inflation tool. After inflation, the first airbag 205 arranged on the outer surface of the mounting column 206 will deform and expand outward, and its outer surface will fit closely with the inner surface of the pipeline body 10, playing a role of blocking. After inflation, the second airbag 6 arranged in the annular groove 9 will deform and expand inward, and its inner surface will fit closely with the outer surface of the pipeline body 10, playing a role of blocking. The surface fits together to achieve a seal, and then water is injected into the test tank 1 through the water inlet pipe 5 until the water level rises close to the tank mouth.

After the closed water test is completed, the pump body 202 is started, and the water inside the test tank 1 and the pipeline body 10 will be transported to the second tube body 204 through the fixed tube 207. Under the action of the pump body 202, it is discharged from the first tube body 203 into the storage tank 201 for recycling and reuse, thereby avoiding the direct discharge of test water after the closed water test is completed, causing waste of resources, and greatly reducing the waste of water resources.

[0025] Example 2: Figure 1-Figure 5 As shown, the outer surface of the storage tank 201 is fixedly connected to an outer ring block 208 , and the top of the test tank 1 is equidistantly fixedly connected to multiple fixing rods 3 , and the outer surfaces of the multiple fixing rods 3 all slide through the outer surface of the outer ring block 208 .

[0026] The effect achieved by the entire embodiment 2 is that, when in use, by setting the storage tank 201 on the top of the test tank 1, it is helpful to separate the two for easy transportation. By fixing multiple fixing rods 3 on the top of the test tank 1, the outer ring block 208 set on the outside of the storage tank 201 can be slidably passed through, which plays a limiting role and prevents it from shifting on the top of the test tank 1, and is highly practical.

[0027] Working principle: During the water-tightness test of the water supply and drainage pipeline, one end of the pipeline body 10 to be tested is placed inside the mounting block 4 so that it is connected to the test tank 1, and after the first airbag 205 is placed from the other end of the pipeline body 10 to be tested, the first airbag 205 and the second airbag 6 are inflated in turn using an inflation tool. The first airbag 205 arranged on the outer surface of the mounting column 206 will deform and expand outward after inflation, and its outer surface will fit tightly with the inner surface of the pipeline body 10, playing a sealing role. The second airbag 6 arranged in the annular groove 9 will deform and expand inward after inflation, and its inner surface will fit tightly with the outer surface of the pipeline body 10, playing a sealing role. Water is then injected into the test tank 1 through the water inlet pipe 5 until the water level rises to close to the tank mouth, and the U-shaped The scale lines 8 on the outer surface of the tube 7 and its internal liquid level information make it convenient for personnel to calculate the test effect of the water supply and drainage pipeline after the closed water test is completed. After the closed water test is completed, the pump body 202 is started, and the water inside the test tank 1 and the pipeline body 10 will be transported to the second tube body 204 through the fixed pipe 207. Under the action of the pump body 202, it is discharged from the first tube body 203 into the storage tank 201 for recycling and reuse, thereby avoiding the direct discharge of test water after the closed water test is completed, causing waste of resources, greatly reducing the waste of water resources, and by setting the storage tank 201 on the top of the test tank 1, it helps to separate the two for easy transportation, and by fixing multiple fixed rods 3 on the top of the test tank 1, the outer ring block 208 set on the outside of the storage tank 201 can be slidably passed through, which plays a limiting role to prevent it from displacing on the top of the test tank 1, and is highly practical.
