Description

Technical Field

[0001] This application relates to the field of flange cooling technology, specifically a high-temperature test flange structure with a cooling structure. Background Technology

[0002] High-temperature test flanges are flange connections tested or used in high-temperature environments. They are widely used in various industrial sectors operating under high-temperature conditions, such as petrochemicals, power generation, metallurgy, and aerospace. In these fields, high-temperature test flanges can withstand the operating requirements of high-temperature and high-pressure environments, ensuring the stable operation of pipeline systems.

[0003] During use, conventional high-temperature test flanges are prone to damage to the gaskets due to the excessively high temperature conducted by the high-temperature medium, leading to leakage of the high-temperature medium transmitted through the test flange and thus distorting the high-temperature test results. Therefore, it is necessary to provide a high-temperature test flange structure with a cooling structure to solve the above problems. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the purpose of this application is to provide a high-temperature test flange structure with a cooling structure to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this application to solve its technical problem is: a high-temperature test flange structure with a cooling structure, including a flange cover, wherein a cooling water cavity for water circulation cooling of the sealing gasket is opened on the outer end face of the flange cover, the opening of the cooling water cavity faces outward, a sealing plate is sealed at the opening of the cooling water cavity, a cooling water inlet communicating with the cooling water cavity is provided on one side of the sealing plate, and a cooling water outlet communicating with the cooling water cavity is provided on the other side.

[0006] The flange cover is used to connect with the connecting flange of the pressure test pipeline. A sealing gasket is provided between the flange cover and the connecting flange. The sealing gasket is directly opposite the cooling water chamber. A high-temperature medium port is passed through the middle part of the outer end face of the flange cover.

[0007] Furthermore, the cooling water cavity has a stepped hole structure with a wider outer section and a narrower inner section. The wider section of the cooling water cavity is the opening of the cooling water cavity, and the sealing plate is fixed within the wider section of the cooling water cavity.

[0008] Furthermore, the bottom of the flange cover is provided with an annular placement groove, and the sealing gasket is located in the placement groove.

[0009] Furthermore, the cooling water cavity, sealing gasket, and sealing plate are all concentrically arranged.

[0010] Furthermore, the bottom of the flange cover is threadedly connected to a connecting flange, the top of the sealing gasket abuts against the top wall of the placement groove, and the bottom of the sealing gasket abuts against the top of the connecting flange.

[0011] Furthermore, a temperature sensor is installed on the inner end face of the flange cover.

[0012] The beneficial effects of this application are as follows: The high-temperature test flange structure with cooling structure provided by this application forms a structure that can support cooling water circulation inside the traditional flange by setting a cooling water chamber, and at the same time cools the gasket, increasing the service life of the gasket. It solves the technical problem that when conventional high-temperature test flanges are used, the gasket is easily damaged due to the high temperature conducted by the high-temperature medium, which leads to leakage of the high-temperature medium transmitted in the test flange, thus causing the high-temperature test results to be distorted.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1-4 As shown, this application provides a technical solution: a high-temperature test flange structure with a cooling structure, including a flange cover 1, a cooling water chamber 12 for water circulation cooling of the sealing gasket 3 is provided on the outer end face of the flange cover 1, the opening 121 of the cooling water chamber 12 faces outward, a sealing plate 4 is sealed at the opening 121 of the cooling water chamber 12, a cooling water inlet 41 communicating with the cooling water chamber 12 is provided on one side of the sealing plate 4, and a cooling water outlet 42 communicating with the cooling water chamber 12 is provided on the other side.

[0025] The flange cover 1 is used to connect with the connecting flange 2 of the pressure test pipeline 21. A sealing gasket 3 is provided between the flange cover 1 and the connecting flange 2. The sealing gasket 3 is directly opposite the cooling water chamber 12. A high-temperature medium port 11 passes through the middle part of the outer end face of the flange cover 1.

[0026] The cooling water inlet 41 and the cooling water outlet 42 are connected to the cooling water tank. Cooling water enters the cooling water chamber 12 from the cooling water inlet 41 and flows out from the cooling water outlet 42. In this way, the cooling water circulates in the cooling water chamber 12 to cool the sealing gasket 3 at the bottom of the cooling water chamber 12.

[0027] The cooling water cavity 12 has a stepped hole structure with a wide outer section and a narrow inner section. The wide section of the cooling water cavity 12 is the opening 121 of the cooling water cavity 12, and the sealing plate 4 is fixed inside the wide section of the cooling water cavity 12.

[0028] The bottom of the flange cover 1 has an annular placement groove 13, and the sealing gasket 3 is located in the placement groove 13.

[0029] The cooling water chamber 12, the sealing gasket 3, and the sealing plate 4 are all concentrically arranged.

[0030] The bottom of the flange cover 1 is threadedly connected to the connecting flange 2, the top of the sealing gasket 3 abuts against the top wall of the placement groove 13, and the bottom of the sealing gasket 3 abuts against the top of the connecting flange 2.

[0031] A temperature sensor 5 is installed on the inner end face of the flange cover 1.

[0032] In one embodiment, the gasket is cooled during a high-temperature flange test.

[0033] Specifically, the structure can be arranged horizontally or vertically in a whole pipeline of a de-heating and pressure reducing device, or in valve products that require high-temperature testing. Both ends of the test pipeline 21 are provided with connecting flanges 2, and each connecting flange 2 is connected with a flange cover 1.

[0034] After connecting the cooling water inlet 41 and cooling water outlet 42 to the cooling water tank, the high-temperature medium is sent from the high-temperature medium port 11 on one of the flange covers 1 into the test pipe 21 in the middle of the connecting flange 2. A pressure gauge is installed on the high-temperature medium port 11 on the other flange cover 1. At this time, the high-temperature medium flows into the test pipe 21 and fills the test pipe 21. Then the high-temperature medium port 11 that has entered the high-temperature medium starts to pressurize and conduct a sealing test on the test pipe 21. At the same time, the cooling water enters the cooling water chamber 12 from the cooling water inlet 41 and flows out from the cooling water outlet 42. In this way, it circulates in the cooling water chamber 12 to cool the inner wall of the cooling water chamber 12. The heat is conducted to the placement tank 13, thereby cooling the sealing gasket 3 that can be sealed with it and preventing the sealing gasket 3 from being damaged under continuous high temperature.

[0035] In summary, this device, by incorporating a cooling water chamber, creates a structure within the traditional flange that supports cooling water circulation, while simultaneously cooling the gasket. This increases the gasket's service life and solves the technical problem that conventional high-temperature test flanges, during use, are prone to gasket damage due to excessively high temperatures conducted by the high-temperature medium, leading to leakage of the high-temperature medium transmitted through the test flange and thus distorting the high-temperature test results.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
