Description

Technical Field

[0001] The utility model belongs to the technical field of sealing gaskets, and in particular relates to a high-pressure resistant heat exchanger sealing gasket. Background Art

[0002] The detachable plate heat exchanger is made of many corrugated sheets that are stamped at regular intervals, sealed on all sides by gaskets, and overlapped and compressed with a frame and compression spiral. The four corner holes of the plates and gaskets form the distribution pipes and collection pipes of the fluid, while also reasonably separating the hot and cold fluids so that they flow in the flow channels on both sides of each plate respectively, and heat exchange is carried out through the plates. The sealing gasket plays an important role in preventing the fluid inside from flowing out and affecting the heat exchange effect.

[0003] During the use of the sealing gasket, the sealing gasket is easily damaged due to long-term compression, which leads to an increase in the gap between the sealing gasket and the heat exchange plate, making it easy for the fluid inside to flow out and affect the effect of the heat exchanger. In order to solve the above problem, a high-pressure resistant heat exchanger sealing gasket is urgently needed to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to propose a high-pressure resistant heat exchanger sealing gasket in order to solve the problem that during the use of the sealing gasket, the sealing gasket is easily damaged due to long-term compression, which leads to an increase in the gap between the sealing gasket and the heat exchange plate, making it easy for the fluid therein to flow out and affecting the effect of the heat exchanger.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a high-pressure heat exchanger sealing gasket, comprising a heat exchange plate, a mounting groove provided on the surface of the heat exchange plate, a sealing gasket provided in the mounting groove, the sealing gasket being a hollow structure and having a buffer component provided therein, and an extrusion component provided on the outer wall of the buffer component;

[0006] The buffer assembly includes a mounting frame, which is slidably connected to a first baffle through a groove provided on its surface. A telescopic rod is fixedly connected to one side of the first baffle, and a spring is provided on an outer wall of the telescopic rod.

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

[0008] One end of the spring is fixedly connected to the first baffle, and a plurality of first baffles are provided on the surface of the mounting frame and correspond to the shape of the mounting frame.

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

[0010] The other end of the spring is fixedly connected to the mounting frame, and the first baffle is in contact with the inner wall of the sealing gasket.

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

[0012] The extrusion assembly includes a support frame, and the support frame is rotatably connected to a rotating rod through a through hole provided therein, and one end of the rotating rod is fixedly connected to a threaded rod.

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

[0014] The outer wall of the rotating rod is fixedly connected with a fixing ring, and the fixing ring is rotatably connected with the supporting frame through a groove opened therein, and the mounting frame is slidably connected with the second baffle through a groove opened on one side thereof.

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

[0016] The threaded rod is threadedly connected to the second baffle through a threaded hole opened in the second baffle, the support frame is slidingly connected to the second baffle through a groove opened in the sealing gasket, the rotating rod is rotationally connected to the second baffle through a through hole opened in the sealing gasket, and one end of the support frame is fixedly connected to the mounting frame.

[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, a spring is provided inside. When the heat exchange plate squeezes the sealing gasket during use, the spring and the telescopic rod provide a buffer, thereby reducing the squeezing of the sealing gasket. This design reduces the squeezing of the sealing gasket by the heat exchange plate during use, thereby avoiding the possibility of the sealing gasket being damaged by prolonged squeezing. This ensures the sealing of the heat exchange plate and prevents the fluid therein from flowing out, thereby ensuring the performance of the heat exchange plate.

[0019] 2. In the utility model, a second baffle is provided inside. After the sealing gasket is placed in the groove opened by the heat exchange plate and fixed, the threaded rod is driven to move by rotating the rotating rod, thereby driving the second baffle to move, so that the inner wall of the sealing gasket is squeezed by the second baffle so that one side is stretched and tightly adheres to the inner wall of the groove of the heat exchange plate, thereby ensuring close contact between the sealing gasket and the heat exchange plate. Through this design, it is achieved that the second baffle squeezes one side of the sealing gasket so that it can tightly adhere to the inner wall of the groove of the heat exchange plate, thereby increasing its contact with the heat exchange plate and further ensuring the sealing performance of the sealing gasket.

[0027] 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.

[0028] See also Figure 1-5 The utility model provides a technical solution: a high-pressure resistant heat exchanger sealing gasket, comprising a heat exchange plate 1, a mounting groove provided on the surface of the heat exchange plate 1, a sealing gasket 2 provided in the mounting groove, the sealing gasket 2 being a hollow structure and having a buffer component 3 provided therein, and an extrusion component 4 provided on the outer wall of the buffer component 3;

[0029] The buffer assembly 3 includes a mounting frame 31 , which is slidably connected to a first baffle 33 through a groove provided on its surface. A telescopic rod 32 is fixedly connected to one side of the first baffle 33 , and a spring 34 is provided on the outer wall of the telescopic rod 32 .

[0030] One end of the spring 34 is fixedly connected to the first baffle 33. The surface of the mounting frame 31 is provided with a plurality of first baffles 33 corresponding to the shape of the mounting frame 31. The other end of the spring 34 is fixedly connected to the mounting frame 31. The first baffles 33 are in contact with the inner wall of the sealing gasket 2.

[0031] The specific implementation method is as follows: when the sealing gasket 2 is used, when the heat exchange plate 1 presses it, the sealing gasket 2 is squeezed and the first baffle 33 inside is squeezed, so that it moves under force, and at the same time, the spring 34 and the telescopic rod 32 are subjected to force, so that the spring 34 and the telescopic rod 32 provide a buffer, thereby reducing the squeezing of the sealing gasket 2;

[0032] The extrusion assembly 4 includes a support frame 42, which is rotatably connected to a rotating rod 45 through a through hole opened in the support frame 42, and one end of the rotating rod 45 is fixedly connected to a threaded rod 43. The outer wall of the rotating rod 45 is fixedly connected to a fixing ring 44, and the fixing ring 44 is rotatably connected to the support frame 42 through a groove opened in the support frame 42. The mounting frame 31 is slidably connected to the second baffle 41 through a groove opened on one side of the mounting frame 31, and the threaded rod 43 is threadedly connected to the second baffle 41 through a threaded hole opened in the second baffle 41. The support frame 42 is slidably connected to the sealing gasket 2 through a groove opened in the sealing gasket 2, and the rotating rod 45 is rotatably connected to the sealing gasket 2 through a through hole opened in the sealing gasket 2. One end of the support frame 42 is fixedly connected to the mounting frame 31.

[0033] The specific implementation method is as follows: after the sealing gasket 2 is placed in the groove opened in the heat exchange plate 1 and fixed, the threaded rod 43 is driven to move by rotating the rotating rod 45, thereby driving the second baffle 41 to move. Since the second baffle 41 is located in the sealing gasket 2 and its texture is relatively soft, the inner wall of the sealing gasket 2 is squeezed by the second baffle 41 so that one side of the sealing gasket is stretched and tightly adheres to the inner wall of the groove of the heat exchange plate 1, thereby ensuring close contact between the sealing gasket 2 and the heat exchange plate 1.

[0034] Working principle: During the use of the sealing gasket 2, when the heat exchange plate 1 squeezes it, the sealing gasket 2 is squeezed and the first baffle 33 inside it is squeezed, so that it is forced to move, and at the same time, it makes the spring 34 and the telescopic rod 32 subject to force, so that the spring 34 and the telescopic rod 32 are buffered to reduce the squeezing of the sealing gasket 2. After the sealing gasket 2 is placed in the groove opened in the heat exchange plate 1 and fixed, the threaded rod 43 is driven to move by rotating the rotating rod 45, and the second baffle 41 is driven to move. Since the second baffle 41 is located in the sealing gasket 2 and its texture is relatively soft, the inner wall of the sealing gasket 2 is squeezed by the second baffle 41 so that one side is stretched and close to the inner wall of the groove of the heat exchange plate 1, thereby ensuring close contact between the sealing gasket 2 and the heat exchange plate 1.

[0035] 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.
