Description

Subsection leak detection cleaning adapter of automobile air conditioner system
Technical field
The utility model relates to the conversion connector that a kind of automobile air conditioning system is used, and especially relates to a kind of for subsection leak detection cleaning adapter of automobile air conditioner system.
Background technique
Be different from general family expenses or business air conditioner, the compressor of car air conditioner is accessible compressor, and it is complicated severe many that the Environmental Conditions of car air conditioner is wanted, the pollution of high temperature, oil, gas, water, the vibrations of jolting, these factors all can cause Air conditioning duct for automobile to produce leak source, cause the leakage of refrigeration agent.At present on the market the leak hunting method of automotive air-conditioning system is generally had to two kinds, i.e. whole leak detecting and split leak detecting.Whole leak detecting adopts at the two ends of whole air-conditioning system and adds upward pressure, first according to external barometer reading, change to judge whether to exist leak source, the method has the following disadvantages: 1, because vehicle pipeline is very long, there is the process of a transient equiliblium in barometer reading, and this process life period is longer, so operator easily forms erroneous judgement, is more prone to when especially leak source is very little; If 2 leak sources are positioned at vaporizer, the expansion valve under car instrument desk or the position that can not intuitively observe, just can not complete the object of determining leak source; 3, because interface does not mate, when automotive air-conditioning system is cleaned, must user defeat urgent washing agent import to overcome pressure, the careless slightly washing agent that will make leaks, and befouling environment and harm operator are healthy.Therefore, adopting split leak detecting is trend of the times.
If Chinese Patent Application No. is 200820050617.4 to disclose a kind of subsection leak detection cleaning adapter of automobile air conditioner system, comprise joint body, on joint body, have passage, also comprise a stop collar, on stop collar, have spacing hole and locking aperture, joint body one end sleeve enters in the spacing hole of stop collar, is and closely cooperates, and stop collar can be fixed through locking aperture by various links; And utilize spacing hole and joint body one end on stop collar to closely cooperate, moreover, by locking link, through the spacing hole on stop collar, stop collar is fixed up well, can improve the connection sealing between crossover sub and detected pipeline section.
The subsection leak detection cleaning adapter of automobile air conditioner system of said structure has the following disadvantages: this model utility is mainly applicable to old-fashioned being threaded, to a large amount of board-like connections of pressure of using at present, be not very applicable, and between crossover sub and detected member, do not have effective sealing configuration or sealing configuration unreasonable, cause testing result inaccurate.In addition, a set of crossover sub is only applicable to be connected with a kind of detected member of external diameter, as the caliber of detected member changes, needs to adopt different a whole set of crossover sub completely, and applicability is poor.
Model utility content
Given this, the purpose of this utility model is to provide a kind of novel subsection leak detection cleaning adapter of automobile air conditioner system, solve existing crossover sub and be not suitable for the board-like linkage structure of pressure, and and tested pipe fitting between the not good problem of sealability, and simple in structure, convenient and practical.
The utility model solves the technological scheme that its technical problem adopts: a kind of subsection leak detection cleaning adapter of automobile air conditioner system, comprise the first joint, on the first joint, have first passage, first passage front end is provided with the first joint being connected with car air conditioner pipe fitting port, and first passage rear end is provided with the second joint being connected with manometer tube.The first joint is the board-like linkage structure of pressure, is also provided with first ring connected in star on the first joint, in this first ring connected in star, is mounted with the first seal ring.The setting of this first ring connected in star can, so that the first seal ring is difficult for being shifted, improved the stability of product, and the first seal ring improve the sealing between the first joint and tested pipe fitting.
On the first joint, be also provided with kidney-shaped locking aperture, can through kidney-shaped locking aperture, the first joint and various tested pipe fitting be fixed together for various variable locking links.
In first passage, be provided with valve inside, the needs in the time of can meeting leak detection.Further, the second joint is thread type linkage structure, and itself and manometer tube are joined.
As further improvement of the utility model, subsection leak detection cleaning adapter of automobile air conditioner system also comprises the second joint with the first joint secure fit, concrete, the inwall of the first joint and the first joint is provided with internal thread, and one end of the second joint is provided with the outside thread with above-mentioned internal thread secure fit.On the second joint, have the second channel communicating with described first passage.On the outer wall of the second joint, be also provided with the second annular groove and the second seal ring, this second seal ring can improve the sealing between the measured piece unthreaded holes such as the second joint and compressor, evaporator assemblies, condenser.It needs to be noted, the part external diameter of the second joint can change as required, so that with the unthreaded hole of the measured piece different inner diameters such as compressor, evaporator assemblies, condenser is connected, but the other end is without variation, to only need first joint.
The beneficial effects of the utility model:
1, be applicable to a large amount of presser type detected member of using at present, match with current automotive air-conditioning system interconnection technique present situation.
2, by first ring connected in star and the first seal ring are set on the first joint, optimize the sealing configuration between the first joint and detected member, reduced and leak, improved the accuracy detecting, and simple in structure.
3, the main body of crossover sub, the first joint is universal type, as the caliber that runs into detected member is when change, and only needs to change the second joint, has improved applicability, the manufacture quantity of minimizing crossover sub, has reduced cost.
Below with reference to drawings and Examples, the utility model is described in detail.
