Description

Technical Field

[0001] This application relates to the field of gasket technology, and in particular to a beveled gasket. Background Technology

[0002] In industries such as chemical and petroleum, high-pressure heat exchangers are often used to carry and transport high-temperature, high-pressure, and highly corrosive media. It is often necessary to seal the tube box cover and tube box flange of the high-pressure heat exchanger to prevent media leakage.

[0003] Currently, when installing a high-pressure heat exchanger, workers seal the gap between the tube box cover and the tube box flange by lip welding. When the high-pressure heat exchanger is under maintenance, workers need to remove the sealing weld at the lip using a planer. Then, the planed area is ground again on-site. At this point, new seals can be replaced and installed on the high-pressure heat exchanger.

[0004] The maintenance process for the aforementioned seals is quite complex, resulting in low efficiency in the maintenance of high-pressure heat exchangers, which needs improvement. Utility Model Content

[0005] To simplify the inspection and maintenance procedures of seals and increase the maintenance efficiency of high-pressure heat exchangers, this application provides a beveled sealing gasket.

[0006] This application provides a beveled sealing gasket, which adopts the following technical solution:

[0007] A sloping sealing gasket includes a base gasket and a positioning strip fixed to the side wall of the base gasket. The upper side of the base gasket has a first abutment surface, and the lower side of the base gasket has a second abutment surface. The positioning strip is fixed to the side wall of the base gasket.

[0008] By adopting the above technical solution, when workers install the high-pressure heat exchanger, they place the sealing gasket in the gap between the tube box flat cover and the tube box flange. At this time, the workers fix the tube box flat cover to the tube box flange. During the fixing process, the bottom of the tube box flat cover abuts against the first contact surface, and the top of the tube box flange abuts against the second contact surface. At this time, a line seal of a certain width is formed on the sealing contact surfaces of the tube box flat cover and the first contact surface, and the second contact surface and the tube box flange, thereby achieving a seal between the tube box flat cover and the tube box flange of the high-pressure heat exchanger. This setting simplifies the inspection and maintenance steps of the sealing components and increases the maintenance efficiency of the high-pressure heat exchanger.

[0009] Optionally, a blocking strip is fixed on the base pad, the blocking strip is arranged along the length direction of the base pad, and the blocking strip is located on the first abutment surface away from the positioning strip.

[0010] By adopting the above technical solution, the setting of the blocking strip further reduces the possibility of the medium flowing out of the gap between the pipe box flat cover and the pipe box flange. At the same time, the blocking strip can provide positioning assistance for the installation process. When installing the gasket, the gasket can be installed in the correct position by aligning the blocking strip with the bottom of the pipe box flat cover.

[0011] Optionally, the base pad has a placement groove, which is positioned opposite to the blocking strip. The placement groove is located on the second abutment surface away from the positioning strip, and the outer wall of the blocking strip can abut against the inner wall of the placement groove.

[0012] By adopting the above technical solution, when staff recycle the sealing gaskets, multiple sealing gaskets can be stacked by the cooperation of the blocking strip and the placement groove. This setting facilitates the storage of sealing gaskets and improves the space utilization rate of sealing gaskets during storage.

[0013] Optionally, a blocking groove is formed between the positioning strip and the bottom pad, and the inner wall of the blocking groove can abut against the side wall of the flat cover of the high-pressure heat exchanger tube box.

[0014] By adopting the above technical solution, when the worker installs the gasket, the worker manipulates the positioning strip to make it abut against the side wall of the pipe box flange, that is, the side wall of the pipe box flange abuts against the inner wall of the blocking groove. At this time, the side wall of the pipe box flange abuts against the second abutting surface. This setting realizes the positioning of the gasket, which makes it easier for the worker to install the gasket correctly.

[0015] Optionally, the height of the bottom pad near the end of the positioning strip is less than the height of the bottom pad away from the positioning strip, and the positioning strip is arranged parallel to the height direction of the high-pressure heat exchanger tube box flat cover.

[0016] By adopting the above technical solution, when the workers install the sealing gasket, the side wall of the pipe box flange abuts against the second contact surface, and the side wall of the pipe box flange abuts against the inner wall of the blocking groove. Then, the workers install the high-pressure heat exchanger so that the side wall of the pipe box flat cover abuts against the first contact surface. At this time, the position of the first contact surface on the bottom gasket is subjected to pressure from the pipe box flat cover, and the first contact surface fits against the side wall of the pipe flat cover. This setting improves the sealing performance of the sealing gasket.

[0017] Optionally, the blocking strip is cylindrical, and the cross-section of the blocking strip is semi-circular.

[0018] By adopting the above technical solution, the setting of the blocking strip facilitates the positioning of the pipe box cover by the staff, making the fit between the pipe box cover and the pipe box flange tighter.

[0019] Optionally, the sidewall of the base pad is provided with ventilation holes, which are respectively connected to the first contact surface, the second contact surface, and the sidewall of the base pad.

[0020] By adopting the above technical solution, when the staff removes the sealing gasket, the staff will...

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When the operator installs the high-pressure heat exchanger, the operator places the sealing gasket in the gap between the tube box cover and the tube box flange. At this time, the operator controls the tube box cover to be fixed on the tube box flange, with the side wall of the tube box cover abutting against the first contact surface and the side wall of the tube box flange abutting against the second contact surface. This setting simplifies the inspection and maintenance steps of the seal and increases the maintenance efficiency of the high-pressure heat exchanger.

[0023] 2. When the staff removes the gaskets, they match the blocking strips of different gaskets with the placement slots to achieve stacking of the gaskets. This setup increases the space utilization rate when stacking gaskets. Attached Figure Description
