Description

Technical Field

[0001] This utility model relates to the field of hydraulic sealing tests, and in particular to a hydrostatic sealing test structure for water and electricity pipes. Background Technology

[0002] Hydrostatic strength is one of the important properties of pipe materials, and it is a crucial indicator for ensuring product safety. The service life of plastic pipes depends on their resistance to heat and oxygen aging and creep deformation characteristics under long-term hydrostatic pressure. The pressure resistance time and maximum instantaneous failure pressure of the pipe under constant internal pressure and temperature for a long period of time are testing items for pipe manufacturers and testing institutions. The pressure resistance test involves subjecting a given section of plastic pipe sample to a specified constant internal pressure for a given time and observing whether the sample fails. Sealing joints are installed at both ends of the sample, connecting it to the sample and the pressure device; they must not subject the sample to axial force or cause damage. Currently, the sealing joint used involves inserting the pipe sample onto the plug, then placing a tapered pipe clamp over the pipe sample, and finally tightening a nut into the threaded connection of the plug. Test pressure is applied to the pipe sample from the other end. However, the existing method involves using a tapered pipe clamp as a single, fixed-size metal clamp over the pipe sample. Since the diameter of the test pipe sample fluctuates within the standard tolerance range, if the diameter is too large within this range, it can cause deformation of the pipe sample during installation, leading to installation difficulties. Conversely, if the diameter is too small within the tolerance range, poor sealing can occur when pressure is applied to the inside of the pipe during the test, affecting the normal conduct of the experiment.

[0003] In existing technologies, such as the Chinese patent application CN211453172U entitled "A Sealing Fixture for Hydrostatic Testing of Plastic Pipes," a joint, a clamping ring, and a locking device are included. One end of the clamping ring is sealed to the joint. The clamping ring is a frustum-shaped structure with its outer diameter gradually decreasing in the direction away from the joint. The clamping ring is composed of at least two arc-shaped clamping plates spliced ​​together. The locking device is provided with a clamping part and is detachably connected to the joint, thus clamping the clamping ring. The clamping ring of this sealing fixture for hydrostatic testing of plastic pipes is composed of at least two clamping plates, which can accommodate the clamping of plastic pipes with different diameters. This avoids damage to the plastic pipe and prevents sealing problems. Moreover, because the clamping ring is spliced, it is easy to assemble and disassemble, and the clamping ring can be reused multiple times. This solves the problem of the original tapered integral pipe sleeve being disposable, saving costs.

[0004] In existing technologies, hydrostatic pressure testing of water and electricity pipes is inconvenient because the size of the fixed connection components is fixed, making it difficult to connect and fix pipes of different diameters.

[0005] Therefore, it is necessary to provide a hydrostatic sealing test structure for water and electricity pipes to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a hydrostatic sealing test structure for water and electricity pipes, which solves the problem that the fixed connection components are difficult to connect and fix to pipes of different diameters due to their fixed size, thus making hydrostatic sealing tests of pipes of different specifications inconvenient.

[0015] Compared with related technologies, the hydrostatic sealing test structure for water and electricity pipes provided by this utility model has the following beneficial effects:

[0016] This utility model provides a hydrostatic sealing test structure for water and electricity pipes. By setting a water injection head, when pipe fixing is required, one end of the pipe is sleeved on the top of the base. At this time, rotating the threaded rod causes the threaded rod to drive the clamping sleeve to tightly press against the top of the pipe, thereby fixing one end of the pipe inside the base. Then, the water injection head is moved horizontally, causing one end of the water injection head to drive the sealing sleeve to tightly press against one end of the pipe, thus achieving the effect of fixing the pipe and the water injection head. This achieves the effect of fixing pipes of different diameters, thus bringing convenience to the hydrostatic sealing test of pipes of different diameters.

[0017] By setting up lamps, when the pipe expands during the hydrostatic sealing test, the lamps are activated, illuminating the backlight panel. This allows staff to observe the expansion of the pipe from the front, measuring the expansion through the scale groove, thus achieving the hydrostatic sealing test effect.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of a hydrostatic sealing test structure for water and electricity pipes provided by this utility model; Figure 2 for Figure 1 The image shows a front view of a hydrostatic sealing test structure for water and electricity pipes. Figure 3 for Figure 1 The image shows a front view of a sliding block in a hydrostatic sealing test structure for water and electricity pipes. Figure 4 for Figure 1 The diagram shows an enlarged view of point A in a hydrostatic sealing test structure for water and electricity pipes. The hydrostatic sealing test structure for water and electricity pipes includes a support platform 1, a light box 2 fixedly connected to the top of the support platform 1, a backlight plate 3 fixedly fitted to the front of the light box 2, a scale groove 4 on the front of the backlight plate 3, a base 5 fixedly connected to the top of the support platform 1, a threaded rod 6 threadedly fitted to the top of the base 5, a clamping sleeve 7 threadedly fitted to the outside of the threaded rod 6, an anti-slip toothed sleeve 8 fixedly fitted to the top of the base 5, a sliding groove 9 on the top of the support platform 1, and a sliding block 10 movably fitted inside the sliding groove 9. The top of the support platform 1 is fixedly connected to a limiting sleeve 11, and a lifting column 12 is movably sleeved on the top of the limiting sleeve 11. A positioning groove 13 is opened on the front of the lifting column 12. A bolt 14 is threaded on the front of the limiting sleeve 11. A water injection head 15 is fixedly connected to the top of the lifting column 12. A sealing sleeve 16 is fixedly sleeved on the side of the water injection head 15. A conveying mechanism 17 is provided on the side of the support platform 1. A sliding ball 18 is movably sleeved on the front of the sliding block 10. A lamp tube 19 is fixedly installed inside the light box 2. A moving mechanism 20 is provided at the bottom of the support platform 1.

[0025] The front of the water injection head 15 is conical, and the water injection head 15 is located in the center of the side of the base 5. By setting the water injection head 15, when it is necessary to fix the pipe, one end of the pipe is sleeved on the top of the base 5. At this time, the threaded rod 6 is rotated, so that the threaded rod 6 drives the clamping sleeve 7 to tightly press against the top of the pipe, thereby fixing one end of the pipe inside the base 5. Then, the water injection head 15 is moved horizontally, so that one end of the water injection head 15 drives the sealing sleeve 16 to tightly press against one end of the pipe, thereby achieving the fixed connection effect between the pipe and the water injection head 15, thus achieving the fixed connection effect of pipes of different diameters, and bringing convenience to the hydrostatic sealing test of pipes of different diameters.

[0026] The anti-slip toothed sleeve 8 has a U-shaped front and is made of stainless steel. By setting the anti-slip toothed sleeve 8, when the pipe needs to be clamped and fixed, the anti-slip toothed sleeve 8 can greatly improve the friction between the pipe and the base 5, thus avoiding the problem of rotational displacement during the sealing test caused by the relatively smooth surface of the pipe.

[0027] The limiting sleeve 11 is located directly above the sliding block 10, and the limiting sleeve 11 is perpendicular to the water injection head 15. By setting the limiting sleeve 11, when the height of the water injection head 15 needs to be adjusted, the bolt 14 is rotated so that one end of the bolt 14 can be moved out of the positioning groove 13, thereby allowing the lifting column 12 to move up and down inside the limiting sleeve 11, thus achieving the effect of adjusting the height of the water injection head 15.

[0028] The conveying mechanism 17 includes a rotary motor 171, which is fixedly installed on the side of the support platform 1. A threaded post 172 is fixedly connected to the output shaft of the rotary motor 171, and the threaded post 172 is threadedly sleeved inside the sliding block 10. By setting the conveying mechanism 17, when it is necessary to connect and fix the water injection head 15 to the pipe, the rotary motor 171 is started, so that the rotary motor 171 drives the threaded post 172 to drive the sliding block 10 to move horizontally. That is, the water injection head 15 is moved horizontally through the limiting sleeve 11, so that the water injection head 15 is tightly squeezed against one end of the pipe, thereby achieving the connection effect between the pipe and the water injection head 15.

[0029] The number of sliding balls 18 is several, and the several sliding balls 18 are evenly distributed on the front of the sliding block 10. By setting the sliding balls 18, when the sliding block 10 drives the limiting sleeve 11 to move horizontally, the sliding balls 18 can limit the horizontally moving sliding block 10, thereby avoiding the problem of friction between the sliding block 10 and the inner wall of the sliding groove 9 when the sliding block 10 moves horizontally, thus improving the smoothness of the horizontal movement of the sliding block 10, that is, improving the smoothness of the horizontal movement of the water injection head 15.

[0030] There are several lamp tubes 19, which are evenly distributed inside the lamp box 2. When the pipe expands during the hydrostatic sealing test, the lamp tubes 19 are activated so that they can illuminate the backlight panel 3. This allows the staff to measure the expansion of the pipe through the scale groove 4, thereby achieving the effect of the hydrostatic sealing test.

[0031] The moving mechanism 20 includes a support column 201, which is fixedly connected to the bottom of the support platform 1. A sliding wheel 202 is installed at the bottom of the support column 201. By setting up the moving mechanism 20, when the test structure needs to be moved and transported, the support platform 1 is pushed, so that the sliding wheel 202 can drive the support platform 1 to move horizontally through the support column 201, that is, drive the light box 2 to move horizontally, thereby achieving the effect of moving and transporting the test structure, and thus bringing convenience to the adjustment of the working position of the test structure.

[0032] The working principle of the hydrostatic sealing test structure for water and electricity pipes provided by this utility model is as follows:

[0033] Step 1: First, when pipe fixing is required, one end of the pipe is fitted onto the top of the base 5. Then, the threaded rod 6 is rotated, causing the clamping sleeve 7 to tightly press against the top of the pipe, thus fixing one end of the pipe inside the base 5. Next, the water injection head 15 is moved horizontally, causing one end of the water injection head 15 to tightly press against the sealing sleeve 16 against one end of the pipe, achieving a fixed connection between the pipe and the water injection head 15. This allows for the fixing of pipes of different diameters, facilitating hydrostatic sealing tests on pipes of different diameters. When pipe clamping is required, the anti-slip toothed sleeve 8 greatly increases the friction between the pipe and the base 5, making... To avoid the problem of rotational displacement during the sealing test due to the relatively smooth surface of the pipe, when the height of the water injection head 15 needs to be adjusted, the bolt 14 is rotated so that one end of the bolt 14 can be moved out of the positioning groove 13, thereby allowing the lifting column 12 to move up and down inside the limiting sleeve 11, thus achieving the effect of adjusting the height of the water injection head 15. When the water injection head 15 needs to be connected and fixed to the pipe, the rotary motor 171 is started so that the rotary motor 171 drives the threaded column 172 to drive the sliding block 10 to move horizontally, that is, through the limiting sleeve 11, the water injection head 15 is moved horizontally, so that the water injection head 15 is tightly pressed against one end of the pipe, thus achieving the connection effect between the pipe and the water injection head 15.

[0034] Step 2: When the sliding block 10 drives the limiting sleeve 11 to move horizontally, the sliding ball 18 can limit the horizontally moving sliding block 10, thus avoiding the problem of friction between the sliding block 10 and the inner wall of the sliding groove 9 during horizontal movement. This improves the smoothness of the horizontal movement of the sliding block 10, which in turn improves the smoothness of the horizontal movement of the water injection head 15. When the pipe expands during the hydrostatic sealing test, the lamp tube 19 is activated, which illuminates the backlight plate 3, allowing the staff to measure the expansion of the pipe through the scale groove 4, thereby achieving the hydrostatic sealing test effect. When the test structure needs to be moved and transported, the support platform 1 is pushed, so that the sliding wheel 202 can drive the support platform 1 to move horizontally through the support column 201, which in turn drives the lamp box 2 to move horizontally, thus achieving the test structure moving and transport effect, and bringing convenience to the working position adjustment of the test structure.

[0035] Compared with related technologies, the hydrostatic sealing test structure for water and electricity pipes provided by this utility model has the following beneficial effects:

[0036] By setting the water injection head 15, when pipe fixing is required, one end of the pipe is sleeved on the top of the base 5. At this time, the threaded rod 6 is rotated, so that the threaded rod 6 drives the clamping sleeve 7 to tightly press against the top of the pipe, thereby fixing one end of the pipe inside the base 5. Then, the water injection head 15 is moved horizontally, so that one end of the water injection head 15 drives the sealing sleeve 16 to tightly press against one end of the pipe, thereby achieving the fixed connection effect between the pipe and the water injection head 15, thus achieving the fixed connection effect of pipes of different diameters, and bringing convenience to the hydrostatic sealing test of pipes of different diameters.
