Problems solved by technology

This form of sealing structure requires high dimensional accuracy, and the sealing ring is easy to be scratched and damaged during transportation and assembly, which leads to high processing costs of the welded structure, and is prone to leakage and high temperature in the subsequent welding process. There are problems such as the size of the back is out of tolerance, which needs to be improved

Embodiment 1

[0029] Such as figure 1 As shown, an air conditioner high and low pressure pipe assembly includes a high and low pressure pipe fitting 1 and an extruded sealing block 2 . The extrusion sealing block 2 is provided with a perforation for the high and low pressure pipe fittings 1 to pass through, and is used for the extrusion sealing of the pipe end of the high and low pressure pipe fittings 1; Positioning ring 11, and sleeved with a rubber ring 4 that abuts against the limiting ring 11 on one side and squeezes and seals on the other side. The block 2 is abutted to prevent the high and low pressure pipe fittings 1 from detaching from the extruded sealing block 2, and then the rubber ring 4 is used to extrude and seal the other side by abutting the limit ring 11 on one side. After the sealing block 2 is pressed, the extrusion sealing effect is realized, which has the effects of significantly reducing product cost and significantly improving sealing quality and convenience. It sh...

Embodiment 2

[0034] The difference between the second embodiment and the first embodiment is that the rubber ring 4 in the second embodiment is the second sealing ring 4b. Both sides of the second sealing ring 4b are provided with second sealing convex rings. The second sealing protruding ring 44 protrudes from the metal ring 3 , and the second sealing protruding ring 44 on one side abuts against the limiting ring 11 , and the second sealing protruding ring 44 on the other side is used for extrusion sealing. Therefore, the second sealing bead 44 passing through the two sides of the second sealing ring 4b respectively protrudes from the corresponding side, and the second sealing bead 44 on one side abuts against the limit ring 11, and the second sealing bead 44 on the other side The second sealing protruding ring 44 is used for extrusion sealing, thereby forming a stable protection for the second sealing ring 4b, which has the effects of convenient installation, significantly improved seali...

Embodiment 3

[0036] The difference between the third embodiment and the first embodiment is that the rubber rings 4 in the third embodiment are the first sealing ring 4a and the second sealing ring 4b. Both sides of the first sealing ring 4a are provided with first sealing protruding rings 43 . The first sealing protruding ring 43 protrudes from the metal ring 3, and the first sealing protruding ring 43 on one side abuts against the limit ring 11, and the first sealing protruding ring 43 on the other side is used for extrusion sealing; Both sides of the second sealing ring 4 b are provided with second sealing protruding rings 44 . The second sealing protruding ring 44 protrudes from the metal ring 3, and the second sealing protruding ring 44 on one side abuts against the limit ring 11, and the second sealing protruding ring 44 on the other side is used for extrusion seal. Therefore, the first sealing ring 4a and the second sealing ring 4b are matched and connected with the corresponding ...

Abstract

The invention discloses an air conditioner high and low pressure pipe assembly, which relates to the technical field of automobile air conditioner pipelines. and used for extrusion sealing of the pipe ends of the high and low pressure pipe fittings; one end of the high and low pressure pipe fittings passing through the perforation is provided with a limit ring that abuts against the extrusion sealing block, and is sleeved with a side It abuts against the limiting ring, and the other side is used to squeeze and seal the rubber ring, and the rubber ring is sleeved with a metal ring. The invention has the effect of preventing high and low pressure pipe fittings from detaching from the extruded sealing block by contacting the extrusion sealing block through the limit when sealing the pipe end of the high and low pressure pipe fittings, and then abutting against the limiting ring through one side The rubber ring used for extrusion sealing on the other side can achieve the effect of extrusion sealing after installing the fixed extrusion sealing block, which has the effect of significantly reducing product cost and significantly improving sealing quality and convenience.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning pipelines, and more specifically relates to an air-conditioning high and low pressure pipe assembly. Background technique [0002] The high and low pressure pipes of automobile air conditioners are composed of high pressure pipes and low pressure pipes. Under the action of the blower, the air is cooled by the evaporator and then blown into the car to achieve cooling. In the evaporator, the refrigerant is vaporized into gas, and the gas is compressed by the compressor. The high-temperature and high-pressure gas enters the condenser through the high-pressure pipe to condense into a liquid, and then flows through the expansion valve through the high-pressure pipe to the evaporator after drying through the liquid storage drying filter. [0003] In the prior art, the end structure of the high and low pressure pipes of the automobile air conditioner is extruded and sealed by a welded...
