Description

Technical Field

[0001] This utility model relates to the technical field of sealing test equipment, specifically to a reflux pipeline sealing test device. Background Technology

[0002] The water pressure test is often used to check the sealing of water medium return pipes. The operation method is as follows: seal both ends of the return pipe, connect one end to a water source, fill the pipe with water, gradually increase the water pressure to the specified value, usually 1.25 to 1.5 times the working pressure, and maintain it for a period of time, generally 10 to 30 minutes, and observe whether there is any leakage on the surface of the pipe and at the connection position.

[0003] The method of testing the sealing performance of water medium return pipes requires connecting both ends of the return pipe. A connector is needed to connect the water source and the return pipe. For return pipes without threads, a fitting is needed to be fitted onto the end of the return pipe and the outside of the water source delivery pipe, and then screws are used to lock the connection. This results in a lot of time being spent on preparation work when testing the sealing performance of the return pipe; and the preparation time increases exponentially with the number of return pipes being tested at one time.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figures 1-4 A backflow pipeline sealing test device includes: a support platform 1, a test pipe 2 mounted on the top of the support platform 1, the test pipe 2 being connected to an external water source pipe, a Bourdon tube pressure gauge 8 fixedly mounted on the top of the test pipe 2, the water pressure of the water flow in the test pipe 2 being known through the Bourdon tube pressure gauge 8, multiple test sleeves 11 arranged at equal intervals on the test pipe 2 and communicating with the test pipe 2, a backflow pipe inserted into the test sleeve 11, a stop ring 112 fixedly connected inside the test sleeve 11, the stop ring 112 being located below the silicone rubber inflatable sealing ring 9, when the backflow pipe is inserted into the test sleeve 11, the backflow pipe is blocked by the stop ring 112, and the other end of the backflow pipe is blocked, an installation ring groove 111 is opened inside the test sleeve 11, and a silicone rubber inflatable sealing ring 9 is installed in the installation ring groove 111, the silicone rubber inflatable sealing ring 9 being connected to an external air pump.

[0024] This invention involves inserting the return tube into the test sleeve 11 and then inflating the silicone rubber gas sealing ring 9, so that the silicone rubber gas sealing ring 9 fills the gap between the test sleeve 11 and the return tube, thus quickly completing the preparatory work before testing and greatly accelerating the testing efficiency of the return tube's sealing performance.

[0025] Furthermore, a sliding plate 5 is slidably mounted on the top of the support platform 1. Multiple sealing plungers 6 are fixedly connected to the side of the sliding plate 5 near the return pipe. The number of detection sleeves 11 installed on the detection pipe 2 is the same as the number of return pipes and the number of sealing plungers 6. The sealing plungers 6 are inserted into the return pipe. A cylinder 7 is installed on the top of the support platform 1. The movable end of the cylinder 7 is fixedly connected to the sliding plate 5. The sliding plate 5 can be pushed by the cylinder 7, so that the sliding plate 5 slides on the top of the support platform 1, causing the multiple sealing plungers 6 to move towards the corresponding return pipe, so that the sealing plungers 6 can block the end of the return pipe away from the detection pipe 2.

[0026] Furthermore, two spaced connecting rods 3 are fixedly connected to the support platform 1. Multiple equally spaced support bases 31 are fixedly connected to the connecting rods 3. An arc-shaped groove 311 is opened on the support base 31, and the return pipe is placed in the arc-shaped groove 311. Each return pipe corresponds to two support bases 31. By placing the return pipe in the arc-shaped groove 311, the return pipe slides into the detection sleeve 11. Then, the cylinder 7 pushes the slide plate 5 to move, which causes the sealing plunger 6 to press against one end of the return pipe and push the return pipe into the detection sleeve 11 until one end of the return pipe contacts the abutment ring 112. Then, the silicone rubber inflatable sealing ring 9 is inflated by the air pump. The air nozzle on the silicone rubber inflatable sealing ring 9 extends out of the detection sleeve 11 and is connected to the air pump through the air pipe.

[0027] Furthermore, the connecting rod 3 and the support base 31 are made of acrylic sheet; the connection rod 3 and the support base 31 are made of acrylic sheet, and due to the transparent physical property of acrylic sheet, it is easy to observe the return pipe.

[0028] Furthermore, the support platform 1 is a platform that can be raised and lowered in the vertical direction. A lifting device in the prior art can be installed below the support platform 1 to allow it to be raised. Similarly, the water source pipe connected to the detection pipe 2 is a flexible hose. When the support platform 1 is raised, the area below the return pipe can be observed.

[0029] In this utility model, reference Figures 1 to 4 First, place multiple return pipes into the corresponding arc-shaped grooves 311. Then, start the cylinder 7, which pushes the slide plate 5 to move the sealing plunger 6 towards the return pipe, so that the sealing plunger 6 abuts against one end of the return pipe until the return pipe is pushed into the detection sleeve 11, so that the lower end of the return pipe contacts the abutment ring 112. The slide plate 5 continues to move, so that the sealing plunger 6 is inserted into the return pipe to complete the seal at one end of the return pipe. Then, the silicone rubber inflatable sealing ring 9 is inflated and pressurized by the air pump and the air pressure is maintained to seal the lower end of the return pipe. Finally, pressurized water is introduced into the detection tube 2 and waited for 20 minutes to observe whether there is any leakage in the return pipe. During this period, the support platform 1 can be lifted to observe the bottom of the return pipe.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
