Description

Technical Field

[0001] This utility model relates to the field of pipeline strength testing, and in particular to a hydrostatic strength testing device for PE water supply pipes. Background Technology

[0002] The pipe hydrostatic testing machine can test the strength of PE water supply pipes. The machine consists of a water tank testing mechanism, a pump set, and a main unit. This article explains the problems with the water tank. Feedback indicates that a large water tank volume, when testing is limited to a single pipe, wastes resources including water and electricity needed to maintain the tank temperature. Therefore, appropriately adjusting the tank's internal space is beneficial for testing and more energy-efficient. Utility Model Content

[0003] The purpose of this invention is to provide a hydrostatic strength testing device for PE water supply pipes to solve the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0005] A hydrostatic strength testing device for PE water supply pipes includes a water tank, a pump set, and a main unit. The water tank has a water trough, a pressure source, and a water pipe inlet. The water trough has grooves, with each pair of symmetrical grooves forming a group, and there are at least three groups of grooves. The device also includes a baffle that is inserted into a group of grooves to divide the water trough in two.

[0006] Preferably, the baffle has a baffle extension, which forms a hanging position in one of the tanks after the baffle divides the water tank into two.

[0007] Preferably, the water tank has a stepped opening, and the baffle is also equipped with a support frame. When the support frame is laid flat on the stepped opening, at least three hanging positions are formed in the water tank.

[0008] Preferably, the baffle has a baffle groove, which serves as a fixing groove for the support frame.

[0009] Preferably, when the support and baffle are combined and inserted into a set of grooves, the support is constrained by the grooves so that the support and baffle do not separate after being combined.

[0010] Preferably, it also includes a hook, a first clamp, and a second clamp. The hook can be hung on the baffle extension or on the support. The hook has a pull rod for connecting the first clamp. The first clamp is located at one end of the pipe, and the second clamp is located at the other end of the pipe.

[0011] Preferably, the second clamp has an interface, the first clamp has a drain port, and the drain port is connected to a pressure source via a hose.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses baffles to divide the water tank, and the division space can be adjusted according to the needs of the task. In addition, the baffles also have baffle extensions and other hanging positions for hanging pipes. Of course, when there are multiple hanging positions required, the support can be laid flat at the step opening to expand the hanging positions.

[0014] 2. In this utility model, the space divided by the baffle can be large or small. The small space can correspond to the testing task of a single pipe, thereby reducing the demand for energy such as water and electricity, and saving energy and reducing emissions. Attached Figure Description

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] Example 1

[0026] This embodiment presents a hydrostatic strength testing device for PE water supply pipes. Please refer to [link / reference]. Figures 1-6 The hydrostatic strength testing device includes a water tank 1, a pump set, and a main unit (the pump set and main unit are not shown in the figure). The water tank 1 has a water tank, such as... Figure 1 As shown, the water tank consists of a first tank 2 and a second tank 3 located above the first tank 2 and forming a step with it. The two opposite sidewalls of the first tank 2 have two symmetrical grooves 4, which are vertical limiting grooves. Each pair of symmetrical grooves 4 forms a group, and in this embodiment, the first tank 2 has three groups of these grooves 4. In this embodiment, the following are also provided: Figure 2 and Figure 3 The baffle 5 shown is inserted into a set of grooves 4, dividing the first groove 2 in two. (See also...) Figure 1 , Figure 4 and Figure 5 , Figure 1 In the middle, baffle 5 divides the first groove 2 into two grooves, one large and one small. Figure 4 In the middle, the baffle 5 divides the first groove 2 into two grooves with roughly the same volume. Figure 5 In the middle, baffle 5 divides the first groove 2 into two grooves, one large and one small. It should be noted that the groove 4 contains a rubber structure; after baffle 5 is inserted into groove 4, the rubber structure fills the gaps, preventing water from flowing out of the divided grooves. Further explanation: baffle 5 has... Figure 2 and Figure 3 The baffle extension 7 shown forms a hanging position in one of the slots after the baffle 5 divides the first slot 2 into two. For example... Figure 1 In the middle, a hanging position is formed in the larger groove. Figure 5 A hanging position is formed in the smaller groove. Further, in this embodiment, the support 6 can be removed from the baffle groove 17 located on the side of the baffle 5. After removal, the support 6 is laid on the step, thus forming at least three hanging positions in the first groove 2 to meet diverse usage needs. In this embodiment, it should also be noted that the baffle 5 and the support 6 can be used in combination, for example... Figure 1 If the number of mounting positions provided by the middle baffle extension 7 is insufficient for testing, the support 6 can be placed on the step to provide more mounting positions.

[0027] Please see Figures 1-6 In this embodiment, the structure used in the test also includes a pressure source 15 connected to the pump set and a water pipe outlet 16 connected to the pipeline (the water pipe outlet 16 is usually used with a water pipe; for example, when the aforementioned divided tank needs water, the water pipe can be placed in the tank for water supply). This embodiment also includes a hook 8, a first clamp 10, and a second clamp 11. The hook 8 can be hung on the baffle extension 7 or on the support frame 6. The hook 8 has a pull rod 9, which can be used to connect the first clamp 10. The first clamp 10 is located at one end of the pipeline, and the second clamp 11 is located at the other end of the pipeline. Further, the second clamp 11 has an interface 12, and the first clamp 10 has a drain outlet 13, which is connected to the pressure source 15 via a flexible hose 14. This embodiment works as follows: First, water is injected into the first tank 2, and the water temperature is maintained by the electric heating structure (not shown in the figure) inside the tank. Second, the first clamp 10 and the second clamp 11 are used to clamp and seal both ends of the pipe. After sealing, water is injected into the pipe to squeeze out the air inside the pipe and lock the outlet 13. Third, the pipe is placed in the first tank 2 and submerged in water. Pressure is continued to be applied to the pipe. After pressure holding and multiple tests, the pipe strength value and limit value are detected.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
