Description

Technical Field

[0001] This utility model relates to the field of sealing connection technology, specifically to an integrated sealing connection device for a high-pressure vessel and a heat exchanger. Background Technology

[0002] In industries such as chemical, petroleum, and power, high-pressure vessels and heat exchangers are common critical equipment. Traditional connection methods often use flange connections, which, while simple in structure and easy to disassemble, suffer from problems such as uneven bolt tightening force leading to uneven stress on the sealing surface, and easy aging and damage of gaskets. These issues can easily cause media leakage, resulting not only in material loss and environmental pollution but also potentially leading to safety accidents.

[0003] Because the sealing performance of flange connections is greatly affected by temperature and pressure changes, gaskets are prone to failure under high temperature and high pressure conditions, and frequent replacements increase maintenance costs and downtime.

[0004] To address this, an integrated sealing connection device for high-pressure vessels and heat exchangers is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated sealing connection device for high-pressure vessels and heat exchangers in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An integrated sealing connection device for a high-pressure vessel and a heat exchanger includes a high-pressure vessel, a heat exchanger, and a pipeline. A flange is bolted to the connection end of the high-pressure vessel and the heat exchanger, and a sealing component is inserted into the flange, the connection end, and the connection end to seal the gap between the flange and the high-pressure vessel and the heat exchanger. An elastic component is connected to the end face of the flange, and a bellows is connected to the flange and the elastic component. The end face of the elastic component is fixedly connected to the end of the pipeline.

[0008] Furthermore, the sealing assembly includes a sealing ring disposed on the flange end face and inserted into the connection end of the high-pressure vessel / heat exchanger. The surface of the sealing ring has an annular groove, and a hollow rubber ring is fitted into the annular groove.

[0009] Furthermore, the sealing ring is made of spring steel, and the cross-section of the sealing ring is L-shaped.

[0010] Furthermore, the elastic component includes a threaded rod fixedly installed on the end face of the flange, a limiting ring fixedly sleeved on the surface of the threaded rod, a connecting ring sleeved on the surface of the threaded rod, a spring sleeved on the surface of the threaded rod, and the two ends of the spring being fixedly connected to the opposite surfaces of the flange and the spring, respectively, and a nut threadedly sleeved on the top end of the threaded rod.

[0011] Furthermore, the two ends of the bellows are fixedly connected to the end faces of the flange and the connecting ring, respectively, and the bellows is made of high-temperature and high-pressure resistant rubber material.

[0012] Furthermore, the hollow rubber ring is located in the annular groove on the surface of the sealing ring, and when the sealing ring is inserted into the connection end of the high-pressure vessel / heat exchanger, the surface of the hollow rubber ring is in contact with the inner wall of the connection end of the high-pressure vessel / heat exchanger.

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

[0014] By inserting the sealing assembly into the flange and the interior of the connection end with the high-pressure vessel and heat exchanger, the high-temperature and high-pressure gas makes the sealing assembly fit tightly against the inner wall of the connection end of the high-pressure vessel / heat exchanger, effectively filling the gap between the flange and the connection end of the high-pressure vessel / heat exchanger, preventing the leakage of the medium, and compensating for thermal expansion and mechanical vibration through the elastic deformation of the elastic component and the bellows itself, maintaining the stability of the sealed connection.

[0024] like Figures 1 to 4 As shown, an integrated sealing connection device for a high-pressure vessel and a heat exchanger includes a high-pressure vessel 1, a heat exchanger 2, and a pipe 7. A flange 3 is bolted to the connection end of the high-pressure vessel 1 and the heat exchanger 2, and a sealing component 4 is inserted into the flange 3, the connection end, and inside the connection end to seal the gap between the flange 3 and the high-pressure vessel 1 and the heat exchanger 2. Figure 3 and Figure 4 As shown, specifically, the sealing assembly 4 includes a sealing ring 401 disposed on the end face of the flange 3 and inserted into the connection end of the high pressure vessel 1 / heat exchanger 2. The surface of the sealing ring 401 is provided with an annular groove 402, and a hollow rubber ring 403 is fitted onto the annular groove 402.

[0025] More specifically, the sealing ring 401 is inserted into the end face of the flange 3 and the connection end of the high-pressure vessel 1 / heat exchanger 2. The tight fit of the sealing ring 401 forms a preliminary seal. The hollow rubber ring 403 is fitted on the sealing ring 401 to further enhance the sealing effect. When the sealing ring 401 is under pressure, the hollow rubber ring 403 is deformed and fills the tiny gap between the inner walls of the connection end of the sealing ring 401, thereby improving the reliability of the seal.

[0026] In some practical applications, the sealing ring 401 is made of spring steel, and the cross-section of the sealing ring 401 is L-shaped.

[0027] More specifically, the sealing ring 401 is made of spring steel, which has good elasticity and strength and can withstand stress under high pressure.

[0028] like Figure 3 and Figure 4 As shown, specifically, the hollow rubber ring 403 is located in the annular groove 402 on the surface of the sealing ring 401. When the sealing ring 401 is inserted into the connection end of the high pressure vessel 1 / heat exchanger 2, the surface of the hollow rubber ring 403 is in contact with the inner wall of the connection end of the high pressure vessel 1 / heat exchanger 2.

[0029] More specifically, when the sealing ring 401 is inserted into the interior of the connection end of the high-pressure vessel 1 / heat exchanger 2, the surface of the hollow rubber ring 403 fits tightly against the inner wall of the connection end, which can effectively prevent the medium from leaking from the gap between the sealing ring 401 and the inner wall of the connection end, ensuring the reliability of the sealing connection.

[0030] An elastic component 6 is connected to the end face of flange 3, and a bellows 5 is connected between flange 3 and elastic component 6. The end face of elastic component 6 is fixedly connected to the end of pipe 7; for example Figure 1 , Figure 2 and Figure 3 As shown, specifically, the elastic component 6 includes a threaded rod 601 fixedly installed on the end face of the flange 3. A limiting ring 602 is fixedly sleeved on the surface of the threaded rod 601. A connecting ring 603 is sleeved on the surface of the threaded rod 601. A spring 604 is sleeved on the surface of the threaded rod 601. The two ends of the spring 604 are fixedly connected to the flange 3 and the opposite surface of the spring 604, respectively. A nut 605 is threadedly sleeved on the top end of the threaded rod 601.

[0031] More specifically, the combination of the connecting ring 603, the spring 604, and the bellows 5 can generate elastic force to compensate for thermal expansion and mechanical vibration, maintain the stability of the connection between the flange 3 and the pipe 7, and the nut 605 is threaded onto the top of the threaded rod 601 and limits the compensation displacement of the connecting ring 603 through the limiting ring 602 on its surface.

[0032] like Figure 3As shown, in some practical applications, the two ends of the bellows 5 are fixedly connected to the end faces of the flange 3 and the connecting ring 603, respectively, and the bellows 5 is made of high temperature and high pressure resistant rubber material.

[0033] More specifically, the bellows 5, made of high-temperature and high-pressure resistant rubber material, allows for a certain degree of axial displacement while ensuring a seal, thus providing elastic compensation.

[0034] In summary: By inserting the sealing component 4 into the flange 3 and the interior of the connection end with the high-pressure vessel 1 and the heat exchanger 2, the high-temperature and high-pressure gas makes the sealing component 4 fit tightly against the inner wall of the connection end of the high-pressure vessel 1 / heat exchanger 2, which can effectively fill the gap between the flange 3 and the connection end of the high-pressure vessel 1 / heat exchanger 2, prevent the leakage of the medium, and compensate for thermal expansion and mechanical vibration through the elastic deformation of the elastic component 6 and the bellows 5, thus maintaining the stability of the sealed connection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
