Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchanger sealing gaskets, in particular to a special-shaped sealing gasket for a heat exchanger. Background Art

[0002] The heat exchanger gasket is one of the core components of the plate heat exchanger. It is a sealing element used to ensure that the fluid inside the heat exchanger does not leak. The main function of the gasket is to ensure that the various fluids inside the heat exchanger can flow according to the design requirements when the heat exchanger is working, preventing leakage. In addition, the gasket can also prevent cross-flow between the heat exchange media and ensure the normal operation of the heat exchanger.

[0003] When replacing the existing heat exchanger gasket, the gasket is relatively soft and thus will form a different shape, which makes it impossible to correspond well to the groove on the heat exchanger metal plate, making it inconvenient to install the sealing strip. In addition, the existing heat exchanger gasket does not fit tightly enough with the groove between the metal plate, which may cause leakage of the heat exchange medium, thereby affecting the normal operation of the heat exchanger. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art that the existing heat exchanger sealing gasket is inconvenient to replace and the groove between the sealing gasket and the metal plate is not tightly enough, and to propose a special-shaped sealing gasket for a heat exchanger.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A special-shaped sealing gasket for a heat exchanger includes a sealing gasket body, a mounting plate connected to the bottom of the sealing gasket body, a plurality of springs connected to the bottom of the mounting plate, and the other ends of the plurality of springs are connected to the same fixed plate, and the plurality of springs are arranged equidistantly along the top of the fixed plate, and the number of the springs is an even number.

[0007] As a further description of the above technical solution:

[0008] A plurality of positioning pieces are connected to the outer side wall of the sealing gasket body, and the cross section of the positioning piece is T-shaped.

[0009] As a further description of the above technical solution:

[0010] The number of the positioning pieces is an even number, and the sealing pad body and the positioning pieces are both made of nitrile rubber.

[0011] As a further description of the above technical solution:

[0012] A first placement groove is formed on the inner side wall of the sealing gasket body, and a support frame is connected to the first placement groove.

[0013] As a further description of the above technical solution:

[0014] Second placement grooves are provided on both sides of the sealing gasket body, and support rings are connected in the second placement grooves.

[0015] As a further description of the above technical solution:

[0016] The support frame is made of stainless steel, and the support ring is also made of stainless steel.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. In the present invention, by providing a fixing plate, a mounting plate and a spring, when the sealing gasket body is squeezed by the groove on the metal plate of the heat exchanger, the sealing gasket body can drive multiple springs to generate elastic force through the mounting plate, and under the action of the elastic force, the sealing gasket body can fit more closely with the inner wall of the groove on the metal plate, thereby improving the sealing effect of the sealing gasket body, avoiding leakage of heat exchange medium and causing the heat exchanger to fail to operate normally, thereby increasing the service life of the heat exchanger.

[0019] 2. In the present invention, by providing a support frame, a first placement groove, a support ring and a second placement groove, the support frame and the support ring can support the sealing gasket body, so that the sealing gasket body can maintain the same shape as the groove on the metal plate, thereby facilitating direct installation of the sealing gasket body, saving the time spent on replacing the heat exchanger sealing gasket, and improving the replacement efficiency of the heat exchanger sealing gasket.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 4 The utility model provides a technical solution: a special-shaped sealing gasket for a heat exchanger, comprising a sealing gasket body 1, a mounting plate 8 connected to the bottom of the sealing gasket body 1, a plurality of springs 9 connected to the bottom of the mounting plate 8, and the other ends of the plurality of springs 9 are connected to the same fixed plate 7, and the plurality of springs 9 are arranged equidistantly along the top of the fixed plate 7, the number of springs 9 is an even number, a plurality of positioning members 2 are connected to the outer side wall of the sealing gasket body 1, the cross section of the positioning member 2 is T-shaped, the number of the positioning members 2 is an even number, and the sealing gasket body 1 and the positioning member 2 are both made of nitrile rubber.

[0027] The specific implementation method is as follows: when the sealing gasket body 1 is squeezed by the groove on one of the metal plates of the heat exchanger, the fixing plate 7 will be supported by the groove on the other metal plate of the heat exchanger, so that the sealing gasket body 1 can drive multiple springs 9 to be compressed through the mounting plate 8, so that the multiple springs 9 generate elastic force, and the multiple springs 9 can drive the sealing gasket body 1 to fit the inner wall of the groove on the metal plate through the elastic force. The support of the elastic force of the spring 9 enables the sealing gasket body 1 to fit more closely with the inner wall of the groove on the metal plate, thereby improving the sealing effect of the sealing gasket body 1, avoiding leakage of heat exchange medium and causing the heat exchanger to fail to operate normally, thereby increasing the service life of the heat exchanger.

[0028] A first placement groove 4 is provided on the inner wall of the sealing gasket body 1, and a support frame 3 is connected to the first placement groove 4. Second placement grooves 6 are provided on both sides of the sealing gasket body 1, and a support ring 5 is connected to the second placement groove 6. The support frame 3 is made of stainless steel, and the support ring 5 is made of stainless steel.

[0029] The specific implementation method is as follows: the support frame 3 and the first placement groove 4 have the same shape as the inner wall of the sealing gasket body 1, and the support ring 5 has the same shape as the second placement groove 6. Therefore, the support frame 3 and the support ring 5 can support the sealing gasket body 1 through the first placement groove 4 and the second placement groove 6, so that the sealing gasket body 1 can maintain the same shape as the groove on the metal plate, thereby facilitating direct installation of the sealing gasket body 1, saving the time spent on replacing the heat exchanger sealing gasket, and improving the replacement efficiency of the heat exchanger sealing gasket. At the same time, the support of the support frame 3 and the support ring 5 can prevent the sealing gasket body 1 from being deformed, so that the sealing gasket body 1 can better fit the inner wall of the groove on the metal plate.

[0030] Working principle: When in use, the sealing gasket body 1, the mounting plate 8, and the fixing plate 7 are placed together in the groove on one of the metal plates of the heat exchanger, so that the bottom of the fixing plate 7 fits against the inner wall of the groove on the metal plate, and the positioning piece 2 fits against the inner wall of the limit groove on the metal plate, thereby limiting the position of the sealing gasket body 1. Then, the sealing gasket body 1 is squeezed through the groove on the other metal plate of the heat exchanger, so that the sealing gasket body 1 can drive multiple springs 9 to be compressed through the mounting plate 8 and generate elastic force, thereby driving the sealing gasket body 1 to fit against the inner wall of the groove on the metal plate, thereby making the sealing gasket body 1 fit more tightly against the inner wall of the groove on the metal plate. When the sealing gasket of the heat exchanger needs to be replaced, the support frame 3 and the support ring 5 can support the sealing gasket body 1, so that the sealing gasket body 1 can maintain the same shape as the groove on the metal plate, thereby facilitating direct installation of the sealing gasket body 1.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
