Description

Technical Field

[0001] This invention provides a device for testing the sealing effect under high temperature and high pressure, belonging to the field of sealing material testing technology. Background Technology

[0002] In many industrial sectors, such as oil extraction, chemical engineering, and aerospace, extreme working environments with high temperatures and pressures are frequently encountered. During these high-temperature, high-pressure environments and operations, effective sealing of various interfaces and gaps is essential to ensure production safety and product quality. Therefore, the sealing performance of sealing materials is particularly critical, and accurate testing of their sealing effectiveness under high-temperature, high-pressure conditions is a crucial step in evaluating their performance.

[0003] Under high temperature and high pressure conditions, sealing materials are subject to significant pressure and temperature variations. For example, increased temperature may cause the sealing material to expand or soften, while high pressure exerts a powerful thrust. If the sealing material detaches, it will damage the original sealing structure, meaning that leaks observed during testing are not due to poor performance of the sealing material itself, but rather to a problem with its fixation. This severely affects the accuracy of the test results and fails to truly reflect the actual sealing capability of the sealing material under high temperature and high pressure.

[0004] Meanwhile, a tight fit between the testing device and the sealing material is crucial when testing the sealing effect. Only with a tight fit can the presence and extent of leakage at the sealing point be accurately detected. Under high temperature and high pressure environments, the fit between the testing device and the sealing material will further deteriorate due to factors such as thermal expansion and contraction and pressure deformation. Gaps between the testing device and the sealing material will cause deviations in the test results, and some leaks may not be detected in a timely and accurate manner, thus affecting the overall testing effect of the device and failing to provide reliable data support for the performance evaluation of the sealing material. Utility Model Content

[0005] The technical problem this invention aims to solve is that changes in the sealing material under high temperature and high pressure conditions can easily lead to material detachment and prevent the material from adhering tightly to the testing device, thereby affecting the accuracy of the test results.

[0006] To address the aforementioned problems, the proposed technical solution is as follows: a sealing effect testing device under high temperature and high pressure, comprising a test chamber and a sealing cover, wherein the sealing cover is disposed on the test chamber; an air pump connected to the test chamber is disposed outside the test chamber, and a heating tube is disposed inside the test chamber; further comprising:

[0007] The placement cylinder and the test assembly are provided. The bottom of the placement cylinder has a through hole, and a sealing block is placed inside the through hole. The placement cylinder is fixedly connected to the bottom of the sealing cover. The sealing block includes a plug and a sealing block. The plug is located inside the through hole, and the sealing block is fixedly connected below the plug and blocks the through hole. A support platform is fixedly installed inside the test chamber, and the test assembly is located above the support platform. The test assembly fits against the sealing block and is connected to the support platform through an elastic sliding component.

[0008] As an improvement, the test assembly includes a support plate and a test paper. The support plate is set on a support platform, and the test paper, which can absorb seepage, is fixedly connected to the support plate and is in close contact with the sealing block.

[0009] As an improvement, the elastic sliding assembly includes a spring, a telescopic rod, and a sliding plate; a groove is provided in the support platform, the telescopic rod is slidably disposed in the groove, and the telescopic rod is fixedly connected to the bottom of the support plate; the sliding plate is slidably disposed in the groove, and the sliding plate is fixedly sleeved on the telescopic rod; the spring is sleeved on the telescopic rod, and the position of the spring corresponds to that of the sliding plate.

[0010] As an improvement, the sealing cover is equipped with a thermometer and a pressure gauge.

[0011] As an improvement, the sealing cover is provided with a feed hole that communicates with the placement cylinder, and a sealing plug is provided in the feed hole.

[0012] As an improvement, the placement tube is provided with a vent hole, and the placement tube contains a test liquid.

[0013] The beneficial effects of this utility model are:

[0014] The plugging block consists of a blocking block and a sealing block. The blocking block is located inside the through-hole, and the sealing block completely seals the through-hole. The test component fits snugly against the plugging block and is connected to the support platform via an elastic sliding component. By setting the blocking block and sealing block together, a complete plugging block is formed, effectively sealing the through-hole. The test component ensures that the plugging block firmly seals the through-hole, preventing the test liquid from leaking out of the through-hole and affecting test accuracy. Simultaneously, the elasticity provided by the sliding component ensures a good fit between the test component and the plugging block even if the plugging block changes shape, further increasing test accuracy.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] according to Figure 1-4 As shown: This utility model provides a sealing effect testing device under high temperature and high pressure: it includes a test chamber 1 and a sealing cover 2, the sealing cover 2 being disposed on the test chamber 1; a thermometer 5 and a pressure gauge 8 are disposed on the sealing cover 2, capable of detecting the temperature and pressure inside the test chamber 1. An air pump 3 connected to the test chamber 1 is disposed outside the test chamber 1, and a heating tube 4 is disposed inside the test chamber 1, the air pump 3 and the heating tube 4 capable of providing suitable pressure and temperature to the test chamber 1; it also includes:

[0022] The placement cylinder 7 and the testing component are provided. The bottom of the placement cylinder 7 has a through hole 17, within which a sealing block 16 is installed. The placement cylinder 7 is fixedly connected to the bottom of the sealing cover 2. Installing the sealing cover 2 allows for easy connection between the placement cylinder 7 and the testing component. The placement cylinder 7 has a vent hole 18, and a test liquid is placed inside. The vent hole 18 ensures consistent pressure and temperature inside and outside the placement cylinder 7, enabling testing of the sealing effect under high temperature and high pressure. The sealing cover 2 has a feed hole 6 communicating with the placement cylinder 7, and a sealing plug is installed inside the feed hole 6, allowing for convenient addition of the specific test liquid into the placement cylinder 7.

[0023] The blocking block 16 includes a blocking block and a sealing block. The blocking block is located inside the through hole 17, and the sealing block is fixedly connected below the blocking block and blocks the through hole 17. A support platform 9 is fixedly installed inside the test chamber 1, and the test component is located above the support platform 9. The test component is in contact with the blocking block 16, and the test component is connected to the support platform 9 through an elastic sliding component.

[0024] like Figure 3As shown, the test assembly includes a support plate 14 and a detection paper 15. The support plate 14 is mounted on the support platform 9, and the detection paper 15, which can absorb seepage, is fixedly connected to the support plate 14, with the detection paper 15 in close contact with the sealing block 16. By setting the detection paper 15, it is possible to detect whether the sealing block 16 leaks liquid, thereby testing the sealing effect.

[0025] like Figure 3 As shown, the elastic sliding assembly includes a spring 11, a telescopic rod 12, and a sliding plate 13. A groove 10 is provided inside the support platform 9, and the telescopic rod 12 is slidably disposed within the groove 10 and fixedly connected to the lower part of the support plate 14. The sliding plate 13 is slidably disposed within the groove 10 and is fixedly sleeved on the telescopic rod 12. The spring 11 is sleeved on the telescopic rod 12, and the positions of the spring 11 and the sliding plate 13 correspond. The spring 11 can exert an upward force on the support plate 14 through the sliding plate 13, thereby ensuring that the detection paper 15 on the support plate 14 remains in contact with the sealing block 16 when the sealing block 16 deforms, guaranteeing the detection effect of the detection paper 15, and preventing the sealing block 16 from detaching from the through hole 17.

[0026] The principle of this utility model

[0027] like Figure 4 As shown, when using this application, first place the plugging block 16 made of the plugging material to be tested into the through hole 17. The plugging block is located in the through hole 17, while the sealing block seals the through hole 17, so that the plugging block 16 is fixedly connected to the placement cylinder 7. Unscrew the sealing plug and add the test liquid into the placement cylinder 7 through the feed hole 6; then put the sealing cap 2 on the test chamber 1, so that the sealing cap 2 and the test chamber 1 form a completely closed space.

[0028] like Figure 2 , 3 As shown, when the sealing cap 2 is placed on the test chamber 1, the sealing block 16 first contacts the detection paper 15 on the support plate 14. As the sealing cap 2 moves downward and connects with the test chamber 1, the sealing block 16 pushes the support plate 14 downward. The support plate 14 drives the telescopic rod 12 and the sliding plate 13 to move downward, and the sliding plate 13 compresses the spring 11. At this time, due to the rebound force of the spring 11, the support plate 14 can exert an upward force on the sealing block 16. On the one hand, this upward force is used to prevent the sealing block 16 from separating from the through hole 17, thus preventing liquid from flowing out of the through hole 17. On the other hand, even if the sealing block 16 deforms under high temperature and pressure, the support plate 14 and the detection paper 15 can still maintain close contact with the sealing block 16 under the action of the spring force of the spring 11, thereby enabling the detection of whether liquid has leaked out and increasing the accuracy of the test.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
