Embodiment Construction
[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0016] like figure 1 As shown, the structure of the housing of the liquid storage drier of the present invention includes a pipe body and a plug 8. The outer diameter of the pipe body is uniform, and one end of the pipe body is arranged to cooperate with the internal thread part 4 with the plug 8, and the internal cavity of the pipe body is sequentially It is set as an internal thread part 4, a seal ring installation part 3, a filter screen installation part 2 and a desiccant accommodating part 1; the inner diameter of the seal ring installation part 3 is smaller than the small diameter of the internal thread part 4, forming a seal ring installation boss; Between the filter installation part 2 and the desiccant accommodating part 1, there is a filter limit protrusion 6, which acts as an axial limit for the filter. The inner diameter of the fil...

The invention discloses a liquid storage drier shell and a manufacturing process thereof, which belongs to the field of automobile air-conditioner components. The liquid storage drier shell comprises a tube body and a plug, wherein the outer diameter of the tube body is uniform; an inner threaded part in match with the plug is arranged at one end of the tube body; an inner threaded part, a sealing ring mounting part, a filtering net mounting part and a drying agent accommodation part are sequentially arranged inside the inner chamber of the tube body; the inner diameter of the sealing ring mounting part is smaller than the outer diameter of the inner threaded part; the inner diameter of the filtering net mounting part is greater than the inner diameter of the sealing ring mounting part; the large thread diameter of the inner threaded part is smaller than the inner diameters of the drying agent accommodation part and the filtering net mounting part; output holes and input holes are formed in tube walls of the filtering net mounting part and the drying agent accommodation part. The manufacturing process comprises the following steps: I, performing backward extrusion to form a tube body blank; II, forming a thread base hole; III, forming the sealing ring mounting part and the filtering net mounting part; IV, forming the inner thread of the inner threaded part; V, forming the input holes and the output holes; VI, manufacturing the plug. The problem that a conventional automobile liquid storage drier shell is insufficient in strength in an inner threaded section at an end part is solved.
Description
technical field [0001] The invention belongs to the field of automotive air-conditioning components, and in particular relates to a housing of a liquid storage drier and a manufacturing process thereof. Background technique [0002] The automotive air conditioning system is equipped with a liquid storage dryer, which is used to remove moisture and impurities in the air conditioning system to ensure that the working state of the air conditioning system remains stable. The existing liquid storage dryer mainly includes a housing, a filter assembly, a drying assembly, an input hole and an output hole. The filter assembly and the drying assembly are arranged in the casing, and the input hole and the output hole are arranged on the casing. The casing is generally a cylinder Shaped or tank-shaped airtight container, when the liquid storage drier is used for a certain period of time, the moisture absorption effect of the molecular sieve of the drying component will become worse, so ...
