Technical Field

[0001] This invention relates to the field of performance testing technology for pipeline connectors, specifically to a performance testing device for pipeline connectors. Background Technology

[0002] In pipeline systems, the sealing and pressure resistance of pipeline connectors (such as clamps and joints) directly affect the safe operation of the system. Therefore, conducting accurate performance tests on them is a key step in ensuring the reliability of pipeline systems, and related testing technologies have become an important research direction in the field of pipeline engineering. Currently, in practical applications, the observation window of traditional pipeline connection performance testing devices is easily blurred by dust, water mist, or media residue during the test, requiring frequent manual wiping, which affects the test efficiency. Furthermore, when changing to a suitable test pipe for different specifications of pipeline connections, it is often necessary to disassemble the internal structure of the device box, which is cumbersome and time-consuming, resulting in high time costs in the test preparation stage. Summary of the Invention

[0003] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different approach. It offers a pipe fitting performance testing device to solve the problems mentioned in the background section.

A bidirectional lead screw is rotatably connected to one side of each mounting block, and a second geared motor for driving the bidirectional lead screw to rotate is provided on the other side. Symmetrically distributed T-shaped blocks are installed on the outer wall of the bidirectional lead screw through nuts. Each T-shaped block is provided with a trapezoidal push block. The output shaft of the second geared motor is connected to one end of the bidirectional lead screw through a coupling to drive the bidirectional lead screw to rotate around its own axis. Two symmetrically distributed slide rails are fixedly provided on the bottom of the inner wall of the housing. Multiple sliders are slidably arranged on the slide rails, and the top of the sliders is fixedly installed to the bottom of the T-shaped blocks by bolts.

[0010] More preferably, in the pipe assembly on one side of the housing, a valve is fixedly installed at the end of the mounting pipe away from the housing; in the pipe assembly on the other side of the housing, a connecting pipe is provided on one side of the main body, and the end of the mounting pipe away from the housing is sealed to the connecting pipe through a high-pressure telescopic hose.

[0011] More preferably, the protective cover has an observation port in the middle, and the inner wall of the observation port is fitted with observation glass.

[0012] More preferably, a U-shaped frame is fixedly installed on the top of the box, and a cleaning scraper is provided on both the side of the U-shaped frame facing the protective cover and the side of the fixed cover facing the protective cover, and the scraping surface of the cleaning scraper is in contact with the outer surface of the protective cover.

[0013] More preferably, the inner wall of the housing is fixedly installed with an installation plate and two symmetrically distributed partition plates, both of which are connected to the installation plate; the outer wall of the installation tube is provided with a sealing plate, and a sealing ring is embedded in the side of the sealing plate facing the partition plate, the outer diameter of the sealing ring being adapted to the outer diameter of the sealing plate; each partition plate is provided with a circular hole for the installation tube to pass through, the diameter of the circular hole being larger than the outer diameter of the installation tube and smaller than the outer diameter of the sealing plate, when the sealing plate is in contact with the partition plate, the sealing ring can seal the gap between the circular hole and the installation tube.

[0014] In a further preferred embodiment, the dividing plate is rotatably connected to a flow guide groove via a rotating block, and the rear end of the box body has a hole that matches the shape of the flow guide groove, through which the flow guide groove can extend to the outside of the box body.

[0015] More preferably, the main body integrates a medium source storage tank, a main pipeline, a pressure sensor, a constant temperature chamber, and a pulse generator; one end of the main pipeline is welded to the interface of the medium source storage tank, and the other end is divided into two branches through a three-way valve; the end of the mounting pipe away from the chamber is connected to the outlet convergence end of the above two branches; the pulse generator is connected in series between the main pipeline and the connecting pipe; the constant temperature chamber is wrapped around the outside of the main pipeline, and through holes are opened on both sides for the pipeline to pass through; the heating / cooling module inside the chamber is fixed to the outer wall of the main pipeline.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This pipeline connection performance testing device, through a cleaning scraper and a protective cover, ensures that the cleaning scraper is always in close contact with the outer surface of the protective cover. During the rotation of the protective cover as it is opened or closed, it can automatically scrape away dust, water mist, and media residues on the observation glass surface, maintaining a clear field of view without the need for manual wiping and avoiding the impact of blurred vision on test monitoring.

[0017] 2. This pipeline connection performance testing device, through the pipeline assembly and adjustment assembly, adopts the threaded connection design of the installation pipe and the butt pipe, and with the pipeline assembly separation function driven by the second gear motor, can quickly disassemble the old butt pipe and replace it with a new specification butt pipe. The whole process does not require disassembling the internal structure of the box, reducing the time cost and operation difficulty of pipeline replacement. 3. In this pipeline connection performance testing device, the guide channel is rotatably connected to the dividing plate via a rotating block, forming a linked drainage structure. When the T-shaped block drives the trapezoidal pusher to separate, the guide channel automatically tilts backward and discharges waste liquid through the rear end hole of the tank; during the replacement of the connecting pipe after the test, the drainage action is triggered synchronously, requiring no additional operation steps and simplifying the waste liquid treatment process. This design avoids the accumulation of excessive waste liquid inside the equipment, preventing the formation of stains on the observation glass surface after the waste liquid evaporates during subsequent tests. If the waste liquid remains and evaporates, its condensate will obstruct the field of vision. The timely drainage function of the guide channel can reduce such problems from the source, ensuring that the observation glass remains clean during subsequent tests and guaranteeing the clarity of test monitoring.

Detailed Implementation

[0021] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Please refer to the appendix carefully. Figure 1-5 A performance testing device for pipeline connectors, comprising a main body 1, and further comprising: The protective component 3, located on the upper part of the main body 1, serves as a protective element during the clamp test and achieves self-cleaning after the test.

[0024] Pipe assembly 4, located on both sides of the inner wall of protective assembly 3, guides the test medium during clamp testing and facilitates the replacement of pipes of different diameters before testing to adapt to clamps of different specifications.

[0025] Adjustment component 7, located at the bottom of the inner wall of protective component 3, is used to adjust the spacing between pipe components 4 and, together with the flow guide 6, enables automatic drainage after the clamp test.

[0026] The main body 1 is equipped with a protective component 3 on its top. Pipe components 4 are slidably installed on both sides of the protective component 3. An adjustment component 7 is installed inside the protective component 3.

[0027] The protective component 3 includes a housing 301 installed on the top of the main body 1. Pipe assemblies 4 are slidably installed through both sides of the housing 301 for installing clamps. A fixed cover 302 is fixedly installed on the top of the housing 301, and a protective cover 303 is rotatably connected to its side wall.

[0028] The adjustment component 7 includes mounting blocks 701 symmetrically distributed on the bottom of the inner wall of the housing 301. A two-way lead screw 703 is rotatably connected through one side of the mounting block 701. A symmetrically distributed T-shaped blocks 705 are installed on the outer wall of the two-way lead screw 703 through a nut. Each T-shaped block 705 is provided with a trapezoidal push block 706.

[0029] The piping assembly 4 includes an installation pipe 401 that is slidably connected to the housing 301, and a connecting pipe 403 is installed at one end of the installation pipe 401 by means of a threaded connection.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, in the pipe assembly 4 on one side of the housing 301, a valve is fixedly installed at the end of the installation pipe 401 away from the housing 301; in the pipe assembly 4 on the other side of the housing 301, the end of the installation pipe 401 away from the housing 301 is sealed to the connecting pipe 2 through a high-pressure telescopic hose 5, and both ends of the high-pressure telescopic hose 5 are respectively fastened to the installation pipe 401 and the connecting pipe 2 through flanges and bolts.

[0031] In this embodiment, as Figure 2 As shown, the protective cover 303 has an observation port in the middle, and the inner wall of the observation port is fitted with observation glass. The joint between the observation glass and the observation port is sealed with high-temperature resistant sealant. The observation glass is made of tempered explosion-proof glass. The test status of the clamp can be observed through the glass.

[0032] In this embodiment, as Figure 1 As shown, a first geared motor 308 is installed on one side of the housing 301. Its output shaft is connected to the rotating shaft of the protective cover 303 via a coupling. This connection structure allows the first geared motor 308 to provide rotational power to the protective cover 303, driving the protective cover 303 to rotate around the rotating shaft. When the first geared motor 308 starts, the protective cover 303 rotates under its driving force, thereby realizing the opening and closing action of the protective cover 303. When the protective cover 303 is closed with the chamber 301, the inner wall of the protective cover 303 will come into contact with the dividing plate 305. At the same time, the sealing strip on the protective cover 303 will come into close contact with the chamber 301, the dividing plate 305 and the fixed cover 302 respectively. Through the elastic deformation of the sealing strip, a reliable sealing structure is formed between the contact surfaces to prevent the leakage of the medium inside the chamber 301 and ensure the safety and sealing of the test process.

[0033] In this embodiment, as Figure 1 As shown, a U-shaped frame 306 is fixedly installed on the top of the housing 301. A cleaning scraper 307 is provided on the side of the U-shaped frame 306 facing the protective cover 303 and the side of the fixed cover 302 facing the protective cover 303. The scraping surface of the cleaning scraper 307 is in close contact with the outer surface of the protective cover 303. When the first geared motor 308 drives the protective cover 303 to rotate around the rotating shaft, thereby opening or closing the protective cover 303 and the housing 301, the outer surface of the protective cover 303 will slide relative to the scraping surface of the cleaning scraper 307. Since the cleaning scraper 307 corresponds to the observation glass on the protective cover 303, during the relative sliding process, the cleaning scraper 307 can scrape off the dust, water mist, or media residue adhering to the surface of the observation glass, thereby maintaining the cleanliness of the observation glass.

[0034] In this embodiment, as Figure 4 and Figure 5 As shown, a second geared motor 704 is mounted on the mounting block 701. The output shaft of the second geared motor 704 is connected to one end of the double-acting lead screw 703 via a coupling. This connection method can stably transmit power and drive the double-acting lead screw 703 to rotate around its own axis. The mounting plate 304 has symmetrically distributed holes, which provide sufficient space for the movement of the T-shaped block 705 and prevent the T-shaped block 705 from interfering with the mounting plate 304 during movement. When the second geared motor 704 starts, its output power is transmitted to the double-acting lead screw 703 through the coupling, causing the double-acting lead screw 703 to rotate. Under the rotation of the double-acting lead screw 703, the two T-blocks 705 that are engaged with it by nuts will move relative to each other along the axis of the double-acting lead screw 703, thereby changing the distance between the two T-blocks 705, thereby causing the two pipe assemblies 4 to move away from or closer to each other accordingly. When the pipe assemblies 4 are far apart, they provide convenient operating space for subsequent disassembly of the connecting pipe 403. In this way, operators can replace the connecting pipe 403 with different diameters according to the test requirements, thereby realizing performance tests on clamps of different diameter specifications, improving the versatility and applicability of the device.

[0035] In this embodiment, as Figure 2As shown, two symmetrically distributed slide rails 702 are fixedly installed on the bottom of the inner wall of the housing 301. The slide rails 702 extend along the length of the bidirectional lead screw 703, providing a clear path guide for the movement of the sliders. Multiple sliders are slidably mounted on the slide rails 702, and the tops of the sliders are fixedly installed on the bottom of the T-shaped block 705 by bolts. When the second reduction motor 704 drives the bidirectional lead screw 703 to rotate, causing the two T-blocks 705 to move relative to or towards each other, the sliders connected to the T-blocks 705 will slide synchronously on the corresponding slide rails 702. Due to the constraint of the slide rails 702, the sliders can only move along the extension direction of the slide rails 702, thereby causing the T-blocks 705 to maintain a stable motion trajectory. This reduces the deflection of the T-blocks 705 during movement caused by uneven force on the bidirectional lead screw 703 or their own weight, thus improving the stability of the T-blocks 705 during movement.

[0036] In this embodiment, as Figure 1 and Figure 3 As shown, the inner wall of the housing 301 is fixedly installed with an installation plate 304 and two symmetrically distributed partition plates 305. Both partition plates 305 are fixedly connected to the installation plate 304. The outer wall of the installation tube 401 is fixedly provided with a sealing plate 402. A sealing ring is embedded on the side of the sealing plate 402 facing the partition plate 305, and the outer diameter of the sealing ring is matched with the outer diameter of the sealing plate 402 to ensure the integrity of the sealing surface. Each partition plate 305 has a circular hole through which the mounting tube 401 passes. The diameter of the circular hole is larger than the outer diameter of the mounting tube 401 to allow the mounting tube 401 to pass smoothly. At the same time, the diameter of the circular hole is smaller than the outer diameter of the sealing disc 402. When the sealing disc 402 and the partition plate 305 are in contact, the sealing ring is compressed and deformed, thereby completely sealing the gap between the circular hole and the mounting tube 401. Through this sealing structure, the partition plate 305 and the mounting plate 304 cooperate to divide the interior of the housing 301 into an independent small cavity. A pressure sensor is installed in this cavity to monitor the pressure inside the cavity. At the same time, a pressure sensor is also installed inside the mounting tube 401 to monitor the pressure of the medium inside the mounting tube 401 in real time. During the test, two pressure sensors simultaneously monitored the internal and external pressures of the mounting pipe 401. By comparing the internal and external pressure data, the sealing performance of the clamp can be determined in a timely manner. If the internal pressure of the cavity rises abnormally, it indicates that there is a leak in the clamp, and the medium seeps into the cavity from the mounting pipe 401, providing dual monitoring assurance for the accuracy of the test results.

[0037] In this embodiment, as Figure 1 and Figure 4As shown, the two sides of the flow guide trough 6 are rotatably connected to two dividing plates 305 via rotating blocks 601. One end of the rotating block 601 is fixedly connected to the side wall of the flow guide trough 6, and the other end is rotatably engaged with the dividing plates 305 via a pin, allowing the flow guide trough 6 to rotate flexibly around the pin. The rear end of the housing 301 has a hole that matches the shape of the flow guide trough 6, through which the flow guide trough 6 extends to the outside of the housing 301, providing a channel for liquid discharge. When the two T-shaped blocks 705 move away from or towards each other under the action of the bidirectional lead screw 703, they will simultaneously cause the two corresponding trapezoidal push blocks 706 to move away from or towards each other. When the trapezoidal push blocks 706 move away from each other, their supporting force on the guide channel 6 gradually decreases. Under its own gravity, the guide channel 6 rotates around the pin of the rotating block 601, presenting a backward tilted state. When liquid medium flows out from the clamp gap during the test, it will fall into the guide channel 6. The tilted guide channel 6 can use gravity to discharge the liquid inside through the hole at the rear end of the box 301 to the outside. As the trapezoidal pushers 706 approach each other, their inclined surfaces gradually push the bottom of the guide channel 6, causing the guide channel 6 to slowly rotate and return to a horizontal state. At this time, the two pipe assemblies 4 are also connected. As the guide channel 6 returns to a horizontal state, the hole at the rear end of the housing 301 gradually closes. The sealing strip set at the edge of the guide channel 6 will come into close contact with the inner wall of the rear end of the housing 301 and the partition plate 305, forming a reliable seal to prevent the medium or pressure inside the housing 301 from leaking through the hole during the test, thus ensuring the sealing performance of the test.

[0038] In this embodiment, as Figure 1 As shown, the main body 1 integrates a medium source storage tank, a main pipeline, a pressure sensor, a constant temperature chamber, and a pulse generator. One end of the main pipeline is welded to the interface of the medium source storage tank, and the other end is divided into two branches through a three-way valve. The first branch is connected in series with a high-pressure pump whose maximum output pressure is not less than the burst test setting value. The end of this branch is equipped with a check valve. The second branch is connected in series with a pressure regulating valve with an adjustment range of 0~10MPa. The end of this branch is equipped with a shut-off valve. The end of the mounting pipe 401 away from the box 301 is connected to the outlet convergence end of the above two branches. The pulse generator is connected in series between the main pipeline and the connecting pipe 2. It is connected to the controller through a cable and can control the pulse frequency of 0.1~10Hz. The constant temperature chamber is wrapped around the main pipeline. It has through holes on both sides for the pipeline to pass through. The heating / cooling module inside the chamber and the temperature sensor fixed on the outer wall of the main pipeline form a closed loop control. The pressure sensor is installed in the middle of the main pipeline to monitor the pressure inside the pipe.

[0039] The specific operation process of this invention is as follows: First, start the second reduction motor 704, which drives the bidirectional lead screw 703 to rotate through the coupling, causing the two T-blocks 705 and the trapezoidal push block 706 to move away from each other. At this time, the pipe assemblies 4 on both sides of the housing 301 separate synchronously with the T-blocks 705. Then, replace the appropriate connecting pipe 403 according to the diameter of the clamp, and connect it to the installation pipe 401 through threaded engagement. After installation, start the second reduction motor 704 in reverse, so that the T-blocks 705 drive the pipe assemblies 4 to move closer to each other until the connecting pipes 403 of the two pipe assemblies 4 are close together. The operator can then install the clamp to be tested on the two connecting pipes 403. During this process, the slide rail 702 and the slider cooperate to guide the movement of the T-shaped block 705, ensuring that the pipe assembly 4 is coaxially connected; at the same time, the trapezoidal pusher 706 gradually pushes the guide channel 6 to rotate around the rotating block 601 to a horizontal state, and its edge sealing strip seals and fits tightly with the rear end of the box 301 and the dividing plate 305, sealing the rear end hole of the box 301. Next, the first reduction motor 308 is started, driving the protective cover 303 to rotate around the rotating shaft and close with the box 301. At this time, the inner wall of the protective cover 303 contacts the dividing plate 305, and its sealing strip is tightly attached to the box 301, the dividing plate 305 and the fixed cover 302 to form a closed test space; the observation glass is fixed with high temperature resistant sealant to enhance the sealing performance. The medium source storage tank inside the main body 1 outputs the medium through the main pipeline. If a pressure resistance and burst test is to be carried out, the high pressure pump of the first branch is turned on. The medium enters the installation pipe 401 through the one-way valve. The output pressure of the high pressure pump can be adjusted according to the test requirements so that the maximum pressure is not less than the burst set value. If a low-pressure airtightness test is to be performed, open the pressure regulating valve of the second branch and adjust the pressure from 0 to 10 MPa to meet the test requirements. The shut-off valve is used to cut off the medium supply in an emergency. The medium is applied to the clamps via the installation pipe 401 and the connecting pipe 403. The valve on one side of the housing 301 controls the output of the medium, and the other side is connected to the connecting pipe 2 of the main body 1 through the flange seal of the high-pressure telescopic hose 5 to form a loop, ensuring the sealing of the medium circulation. The constant temperature chamber regulates the temperature of the medium in the main pipeline through the heating / cooling module, and the temperature sensor provides real-time feedback data to form a closed-loop control, meeting the test requirements under different temperature conditions. The pulse generator is connected in series between the main pipeline and the connecting pipe 2. The pulse frequency of 0.1~10Hz is set by the controller to make the medium pressure change periodically, simulating the working environment of the clamp under dynamic pressure. The pressure sensor inside the mounting pipe 401 monitors the medium pressure in real time. Inside the housing 301, in an independent cavity formed by the dividing plate 305 and the sealing ring of the sealing disc 402, a pressure sensor monitors the external ambient pressure. Comparing the data from both can determine the clamp's sealing performance: if the cavity pressure rises abnormally, it indicates a clamp leak. During the airtightness test, the leak detector uses a probe near the observation port to help detect minute leaks, and the pressure data is used to improve the accuracy of the judgment. If the clamp breaks or leaks during the test, the liquid medium will fall into the guide channel 6. During the explosion test, the tempered explosion-proof glass of the protective cover 303 and the sealing structure of the box 301 will jointly bear the impact to prevent the medium from splashing. After the test, close the medium supply valve and open the return / vent valve to release pipeline pressure. Start the first reduction motor 308 to open the protective cover 303, remove the clamps after testing, and start the second reduction motor 704 to separate the pipeline assembly 4. At the same time, the second reduction motor 704 separates the T-shaped block 705, and the trapezoidal push block 706 moves away from the guide channel 6. The guide channel 6 tilts backward under gravity, and the waste liquid is discharged to the outside through the rear hole of the box 301, completing the test process. The cleaning scraper 307 automatically scrapes away stains on the observation glass surface during the opening / closing of the protective cover 303 to ensure clear observation in the next test.
