Description

Technical Field

[0001] The utility model relates to the technical field of floating head type heat exchangers, in particular to a rapid pressure-pressing device for an interstage cooler of a gas compressor. Background Art

[0002] In a floating head heat exchanger, only one end of the tube sheet at both ends is fixed to the shell, and the other end can move freely relative to the shell, which is called a floating head. The floating head consists of a floating tube sheet, a hook ring and a floating head end cover. It is a detachable connection, and the tube bundle can be pulled out of the shell. The thermal deformation of the tube bundle and the shell does not constrain each other, so no thermal stress will be generated. Its advantage is that it is easy to clean between and inside the tubes, and no thermal stress will be generated.

[0003] However, when a floating head heat exchanger tube bundle leaks, it is impossible to perform a pressure test to check for leaks, and it is impossible to correctly identify the leaking tube bundle, which causes the heat exchanger tube bundle leakage to further deteriorate, making the equipment unable to operate normally or even damaging the equipment. Therefore, a gas compressor interstage cooler rapid pressure test device is needed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a rapid pressurization device for an interstage cooler of a gas compressor, which has the advantages of ensuring that pressurization can be performed under a certain pressure while ensuring that the tube bundle of a heat exchanger is not damaged, and solves the problem that after the heat exchanger tube bundle leaks, it is either replaced or forcibly sealed by using the differential pressure between air pressure and water pressure, which easily leads to further deterioration of the leakage of the heat exchanger tube bundle, making it impossible for the equipment to operate normally or damaging the equipment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gas compressor interstage cooler rapid pressure device, comprising a plug body, the plug body is provided with radial holes and axial holes, and also includes a connecting copper tube;

[0006] The connecting copper tube is welded and installed in the radial hole;

[0007] Wherein, a connecting head is welded and installed on one end of the connecting copper tube away from the plug body.

When performing the pressurization operation, the tapered end of the plug body is wrapped with a water and electricity tape, and the plug body is screwed into the tube bundle port by using a certain knocking force. At this time, the gas source can be connected and installed with the connecting tube farthest from the plug body, thereby realizing the pressurization and leak detection operation in the tube bundle.

[0010] One end of the plug body is designed with a conical plug-shaped structure and both the plug and the tube bundle are made of copper.

[0011] Preferably, the radial hole and the axial hole are both designed with a countersunk structure, the radial hole and the axial hole are interconnected in the plug body, and the axial hole is opened at the tapered end of the plug body.

[0013] Preferably, one end of the connecting copper tube away from the plug body is threadedly mounted with a connecting seat through a connecting head.

[0014] By installing a connecting seat through a connecting head thread at one end of the connecting copper tube away from the plug body, auxiliary structures such as a pressure gauge body and a sealing valve body can be selectively installed during specific operations to ensure safety during pressure application.

[0015] Preferably, a connecting pipe is threadedly installed on one end of the connecting seat away from the connecting copper pipe, and connecting heads are welded and installed on both ends of the connecting pipe.

[0016] A connecting pipe is threadedly installed at one end of the connecting seat away from the connecting copper pipe, and connecting heads are welded and installed at both ends of the connecting pipe, so that the pressing tool can be extended by setting connecting pipes of different sizes.

[0017] Preferably, a pressure gauge body is threadedly mounted on one end of the connecting pipe away from the connecting copper pipe, and a sealing valve body is threadedly mounted on one end of the pressure gauge body away from the connecting copper pipe through the connecting pipe.

[0018] A pressure gauge body is threadedly installed at one end of the connecting pipe away from the connecting copper pipe, and a sealing valve body is threadedly installed at one end of the pressure gauge body away from the connecting copper pipe through the connecting pipe, so that the pressure in the tube bundle can be monitored through the pressure gauge body, and at the same time, the pressurization operation can be stopped in time by opening and closing the sealing valve body.

[0019] Preferably, a connecting pipe is threadedly installed at one end of the sealing valve body away from the connecting copper pipe and is connected to the input gas source through the connecting pipe.

[0020] A connecting pipe is threadedly installed on one end of the sealing valve body away from the connecting copper pipe and is connected with the input gas source through the connecting pipe, thereby facilitating the access operation of the input gas source.

[0021] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0022] The utility model provides a plug body, and opens radial holes and axial holes on the plug body to connect the copper tube, and welds and installs the copper tube in the radial hole. At the same time, a connector is welded and installed at one end of the connecting copper tube away from the plug body. When performing specific operations, radial holes and axial holes are opened on the plug body, and the connecting copper tube is welded and installed at the radial hole. The connecting copper tube and the connecting tube are installed as connecting tubes through the connector and the connecting seat, and the pressure gauge body and the sealing valve body are connected and installed with the connecting copper tube by the same means. When performing the pressure-pressing operation, the conical end of the plug body is wrapped with a water and electricity tape, and the plug body is screwed into the tube bundle port by using a certain knocking force. At this time, the gas source can be connected and installed with the connecting tube farthest from the plug body, thereby realizing the pressure-pressing and leak-checking operation in the tube bundle, and achieving the effect of ensuring that the pressure-pressing can be performed under a certain pressure and that the tube bundle of the heat exchanger is not damaged.
