The utility model discloses the air treatment unit for the automobile braking has removed the regeneration air reservoir to connecting pieces such as support, trachea, air pipe connector have been reduced, it is more convenient to make to arrange, thereby has reduced whole car cost and part dead weight. The backflow stop valve is integrated inside the multi-loop protection valve, the problems of difficulty in processing, low reliability and the like are solved, and the universality of the air dryer is improved.
Description
Technical field
The utility model relates to the automobile brake technical field, and more particularly it is a kind of automobile brake air conditioner unit.
Background technique
Present air conditioner unit mainly contains and does not take back flow shutoff valve and backflow stop valve and be integrated in two kinds of forms in the air drier body.
Do not take back the air conditioner unit of flow shutoff valve main integrated combination type air exsiccator and multiloop Protective valve; for realizing the pulse cleaning of air conditioner unit siccative; need to dispose in addition support, tracheae and the pipe joint etc. of regeneration gas cylinder and connection regeneration gas cylinder; it is big not only to take the system layout space, and cost height, assembly process complexity, labor strength height (as shown in Figure 1).
The backflow stop valve is integrated in the intrinsic air conditioner unit assembly of air drier, because air drier body interior space is less, complicated pore is more, for realizing the pulse cleaning of air conditioner unit siccative, need elongated air-flow path of processing in the exsiccator body, but be subjected to processing conditions and exsiccator influence of wall thickness, this hole difficulty of processing is big, the reject rate height, quality of processing is difficult for guaranteeing simultaneously, easily causes mutual gas blowby between each pore.Because the backflow stop valve is integrated in the exsiccator body interior, the versatility that makes exsiccator and four-loop protection valve be combined into various function air conditioner units reduces (as shown in Figure 2) greatly.
Need to prove in Fig. 1, Fig. 2: 4 are air conditioner unit, and 5 are the regeneration gas receiver, and 6 is air compressor, and 7 is gas holder, and 8 is redundant loop.
Summary of the invention
The problem big for the resolution system arrangement space, that assembly process is complicated and versatility is low, the utility model provide a kind of stop valve that refluxes to be integrated in the air conditioner unit of four-loop protection valve.
The purpose of this utility model reaches by following measure: the automobile brake air conditioner unit; comprise air drier 10, backflow stop valve 3, multiloop Protective valve 2; it is characterized in that described backflow stop valve 3 is integrated in the multiloop Protective valve 2, be integrated with in the outlet bubbling air exsiccator 10 of backflow stop valve 3.
In technique scheme, described multiloop Protective valve 2 or for four-loop protection valve or be five loop protection valves or be six loop protection valves.
In technique scheme, be integrated with backflow stop valve 3 in the 4th outlet 24 in the described multiloop Protective valve 2.
The utility model automobile brake has following advantage with air conditioner unit: 1. owing to removed the regeneration gas cylinder, thereby reduced links such as support, tracheae, gas-tpe fitting, make arrange more convenient, thereby reduced integral vehicle cost and part deadweight.Problems such as the stop valve that 2. refluxes is integrated in multiloop Protective valve inside, and processing difficulties and reliability are low have obtained solution, and the versatility of air drier is improved.
Description of drawings
Fig. 1 arranges schematic representation for the air conditioner unit that does not contain the backflow stop valve.
Fig. 2 arranges schematic representation for the air conditioner unit that the backflow stop valve is integrated in exsiccator inside.
Fig. 3 is the utility model automobile brake air conditioner unit schematic diagram.
Fig. 4 is the utility model automobile brake air conditioner unit structural representation.
Embodiment:
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to qualification of the present utility model, simultaneously by illustrating that advantage of the present utility model will become clear more and understands easily.
Consult accompanying drawing as can be known: the automobile brake air conditioner unit; comprise air drier 10, backflow stop valve 3, multiloop Protective valve 2; it is characterized in that described backflow stop valve 3 is integrated in the multiloop Protective valve 2, be integrated with in the outlet bubbling air exsiccator 10 of backflow stop valve 3.Multiloop Protective valve 2 or for four-loop protection valve or be five loop protection valves or be six loop protection valves.Be integrated with backflow stop valve 3 (need to prove: backflow stop valve 3 also can be integrated in other outlet in the multiloop Protective valve 2, as first air outlet 21, second air outlet 22, the 3rd air outlet 23 etc.) in the 4th outlet 24 in the multiloop Protective valve 2.
It is as follows to describe working procedure of the present utility model below in detail: in vehicle traveling process; from the pressurized air of air compressor in interface 11 enters air drier 10; because decrease of temperature produces condensed water; partial condensation water temporal aggregate is in the bottom, big chamber of combination type air exsiccator (also can adopt the exsiccator of other type) body; pressurized air is through super-dry; moisture and greasy dirt are dried agent absorption and are trapped in desiccant surface, and dried clean air is through one-way valve 12; dryer export 13; inlet 1 to first air outlet 21 of four-loop protection valve 2; second air outlet 22; 23 backs, the 3rd air outlet feed gas cylinder.Pressurized air flows into the 4th air outlet 24 of four-loop protection valve 2 simultaneously through the outlet 13 of exsiccator 10, in the 24 bubbling air exsiccators 10 of the 4th air outlet.
When system pressure reaches cut-out pressure, feather valve in the exsiccator 10 is opened, promote piston and open drain tap, from the pressurized air of air compressor and be trapped in exsiccator 10 cavitys condensed water directly discharge from relief opening 14, realize the air compressor offloading functions.Simultaneously owing to exist pressure to fall, pressurized air the 4th air outlet 24 on the integrated backflow stop valve 3 from the four-loop protection valve 2 is back to exsiccator 10 through tracheae, the moisture and the greasy dirt that make pressurized air blowback siccative also will be trapped in desiccant surface are taken away, and discharge from relief opening 14; When backflow stop valve 3 outlet pressures dropped to certain value, the 4th air outlet 24 was closed.
When system was lower than a certain value of cut-out pressure, feather valve and relief opening 14 were closed, and system realizes normal air feed function again.
When system reached cut-out pressure, the feather valve in the exsiccator 10 was opened again and realizes unloading and exsiccator blowback self-cleaning function.So the air feed of realization air conditioner unit and offloading functions circulation are carried out.
The effect that the backflow stop valve is integrated in the air conditioner unit Temperature controlled heater of multiloop Protective valve is: when ambient temperature during at 5 ℃ ± 5 ℃; start the Electric heating appliance of exsiccator 10; can prevent effectively that drainage system from freezing because of freezing; when ambient temperature rose to 20 ℃, Electric heating appliance cut off automatically.
The utility model is installed between air compressor and the gas cylinder; mainly form by the four-loop protection valve of air drier and integrated backflow stop valve; pressurized air from air compressor is played drying and catharsis; prevent the corrosion of pneumatic elements such as various air valves, brake chamber and freeze; and adjusting and protective system pressure, other not specifically described parts (part) are the known technology of existing those skilled in the art.
