Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust pipes, and in particular relates to a quick-connect exhaust pipe. Background Art

[0002] The compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. An exhaust pipe is set on the compressor. The main uses of the exhaust pipe are as follows: 1. Discharge heat: The compressor compresses the gas into a high-temperature and high-pressure state, which contains a lot of heat energy. If it is not discharged through the exhaust pipe, the compressor will overheat and be damaged. The exhaust pipe discharges the high-temperature and high-pressure gas into the condenser, and dissipates the heat through the radiator, so that the gas is cooled into a liquid state, releasing huge heat. 3. Cooling gas: Another function of the exhaust pipe is to cool the gas. The gas discharged from the compressor is very hot, and it is sent to the condenser through the exhaust pipe for cooling, so that the gas is gradually cooled into a liquid state. 3. Provide power: The liquid gas discharged from the exhaust pipe will be sent to the evaporator, where the gas temperature and pressure will be reduced to create a cooling effect. Generally speaking, the compressor housing will have a reserved interface for the exhaust pipe, and the exhaust pipe is connected to the compressor housing by welding. However, the connectivity of the exhaust pipe welded in the interface of the compressor housing is not strong enough, and the exhaust pipe is not sufficiently supported and fixed. After the exhaust pipe is subjected to internal or external pressure for a long time, the connection is more likely to crack and deform. Therefore, the utility model proposes a quick-connect exhaust pipe. Utility Model Content

DETAILED DESCRIPTION

[0025] like Figure 1 and Figure 2 As shown, it is the first embodiment of the utility model.

[0026] A quick-connect exhaust pipe includes: an exhaust pipe body 4, a sealing ring 5 is arranged outside the exhaust pipe body 4, the height of the sealing ring 5 is greater than the depth of the interface of the compressor housing, the outer peripheral shape of the sealing ring 5 matches the inner edge shape of the interface of the compressor housing, and the sealing ring 5 is welded in the interface by fitting. By setting the sealing ring 5, the sealing ring 5 is arranged outside the exhaust pipe body 4, which has the function of strengthening the pipe body strength of the exhaust pipe body 4 at the connection with the compressor housing, strengthening the support and fixation of the exhaust pipe body 4, so that it remains stable and durable during long-term use, and preventing it from being displaced or deformed due to the pressure of the internal gas or the external pressure. The sealing ring 5 is made of steel, and the hardness and stability of the steel ring help to enhance the sealing of the connection of the exhaust pipe body 4 and prevent gas leakage. The sealing ring 4 is pre-welded on the exhaust pipe body 4, and when connecting the compressor housing, it only needs to weld the sealing ring 5 and the compressor housing, which is simple and fast to operate.

[0027] The exhaust pipe body 4 includes a flared pipe section 1, a transition pipe section 2 and a connecting pipe section 3. The inner diameter of the connecting pipe section 3 is larger than the inner diameter of the flared pipe section 1. The transition pipe section 2 smoothly connects the flared pipe section 1 and the connecting pipe section 3. The connecting pipe section 3 is used to connect to the compressor housing. The sealing ring 5 is arranged in the middle of the connecting pipe section 3 to ensure the length of the connecting pipe section 3 inserted into the interface and improve the stability of the connecting pipe section 3 at the interface. The cross section of the transition pipe section 2 is truncated cone-shaped, so that the flared pipe section 1 and the connecting pipe section 3 are naturally transitioned.

[0028] The sealing ring 5 is provided with a first welding chamfer 10 on the inner side connected to the exhaust pipe body 4. A second welding chamfer 9 is provided on the inner side of the expanded pipe section 1. The first welding chamfer 10 or the second welding chamfer 9 can effectively increase the weld length, thereby enhancing the quality and strength of the welding, improving its compression resistance, and effectively reducing the failure rate of welding, thereby improving the welding quality and reliability.

[0029] The outer surface of the sealing ring 5 includes a first welding surface 6, an arc surface 7, and a second welding surface 8. The first welding surface 6, the arc surface 7, and the second welding surface 8 are used for welding the compressor housing.

During welding, the filling material moves from the second welding surface 8 to the first welding surface 6 along the arc surface 7, filling the welding groove and firmly connecting the sealing ring 5 and the compressor housing.

[0030] like Figure 3 The figure shows the second embodiment of the present invention. Based on the first embodiment, the connecting pipe section is bent in an S shape on the side close to the compressor housing. When the oil-containing gas passes through the pipe section with a changed flow direction, centrifugal force is generated, and the gas and oil are automatically separated. The separated oil adheres to the pipe wall and flows downward along the pipe into the compressor housing, while the gas flows upward out of the exhaust pipe body.

The sealing ring 5 is made of steel, and the hardness and stability of the steel material help to enhance the sealing of the connection of the exhaust pipe body 4 and prevent gas leakage.

[0032] The exhaust pipe body 4 includes a flared pipe section 1, a transition pipe section 2 and a connecting pipe section 3. The inner diameter of the connecting pipe section 3 is larger than the inner diameter of the flared pipe section 1. The transition pipe section 2 smoothly connects the flared pipe section 1 and the connecting pipe section 3. The connecting pipe section 3 is used to connect to the compressor housing. The sealing ring is provided with a slot 15, and the connecting pipe section is provided with a block 14. The slot 15 and the block 14 match. The slot 15 and the block 14 are used to make the end of the sealing ring flush with the end of the connecting pipe section. The sealing ring 5 is connected to one end of the connecting pipe section 3 to enhance the structural strength of the end of the connecting pipe section 3 to resist the air pressure inside the compressor. The transition pipe section 2 is provided with a recessed portion 11, and the recessed portion 11 is used to be embedded and connected to other pipes, so that the length of the pipe is increased according to specific circumstances.

[0033] The sealing ring 5 is provided with a first welding chamfer 10 on the inner side connected to the exhaust pipe body 4.
