The light-weight relay valve has the advantages that the appearance is attractive, the processing is convenient, the production cost is reduced, the hidden quality danger is reduced, the production efficiency is high, the light weight of the whole automobile is ensured, and certain popularization values are realized.
Description
Technical field
The utility model relates to a kind of vapour vehicle accessory, especially relates to the relay valve that a kind of automobile air brake system is used.
Background technology
At present, in automobile air brake system, relay valve is comprised of parts such as upper valve body, lower valve body, relay piston, valves conventionally.Wherein, upper valve body, lower valve body relay piston are extensively adopted again production and processing with the following method: aluminium alloy is as material, adopt the technique of pressure die-casting or gravitational casting to make blank, then adopt the process for machining such as car, brill, milling, after processing, also need through burring, clean greasy dirt, infiltration mending-leakage, the technique that is oxidized the complexity such as antirust, mildew-resistant just can be carried out general assembly.During assembling, because the parts such as relay piston, valve are all assemblied in upper and lower valve body, after assembling, also need to adopt the fasteners such as various back-up rings, bolt to carry out fastening.
In addition, valve body and piston very easily produce in press casting procedure, the defects such as pore, sand holes, cold shut, shrinkage porosite, and in machining process, product blank condemnation factor is high, efficiency is low; And due to product structure complexity, all larger at link difficulty costs such as follow-up burring, cleanings; Owing to there being the defects such as pore in valve body, also need the mending-leakage processing of infiltrating, there is again the defect that cost is high, the life-span is not grown in infiltration mending-leakage; Employing oxidation is antirust, anti-mold effect is also bad, easily occurs because of the rotten quality fault causing of valve body surface; During assembly, because fasteners such as adopting various back-up rings, bolt carries out fasteningly, efficiency of assembling is low, difficulty is large, very easily produces again aluminium and cut and wait impurity, the difficult control of process cleanliness level when the parts such as hold-down bolt; And, because adopting metallic material, major part makes, and product total weight is large.
Utility model content
The utility model object is to overcome existing above-mentioned existing problems, and a kind of production, easy to process is provided, good looking appearance, and cost is low, the lightweight relay valve that production efficiency is high.
The technical scheme that the technical matters that the utility model solves adopts is:
A kind of weight-saving relay valve, comprise upper valve body, lower valve body, relay piston, valve seat, relay piston and valve seat are positioned at the cavity of upper valve body and lower valve body, it is characterized in that upper valve body and lower valve body are respectively upper valve body and the lower valve body of nylon material, between upper valve body and lower valve body, be provided with mounting hole, be provided with fastener by mounting hole fastening to upper valve body and lower valve body.
During concrete enforcement, described relay piston and valve seat are respectively piston and the valve seat of nylon material.
During concrete enforcement, above-mentioned fastener is tubular rivet, and tubular rivet is through the mounting hole between upper valve body and lower valve body, tubular rivet be respectively equipped with up and down riveting head, upper valve body and lower valve body are fixed by the upper and lower riveting head of tubular rivet.The utility model is by the upper and lower valve body of tubular rivet riveted, and it is firm, convenient to install, and also can not produce in process of production various wastes, can not pollute working environment.Adopt with prior art compared with the fasteners such as back-up ring, bolt, reduced manufacturing cost.
Adopt the making material of nylon material as upper valve body, lower valve body, relay piston, valve seat, the requirement that meets relay valve lightweight, reduces costs with substituted metal.It has good Combination property, comprises mechanical property, resistance to effect of heat, abrasion test, chemical proofing and self lubricity, and friction coefficient is low, has certain flame resistance, is easy to processing.Because assembly is most of, adopt composite material (nylon) as material, assembly total mass significantly reduces, and to car load, lightweight has important meaning.Adopt nylon material as upper valve body, lower valve body, relay piston, valve seat, the valve body and the piston that have overcome prior art very easily produce in press casting procedure, the defects such as pore, sand holes, cold shut, shrinkage porosite, and in machining process the problems such as product blank condemnation factor is high, efficiency is low, its good looking appearance.It is optimum that nylon material of the present utility model adopts nylon 2730 materials.
During concrete enforcement, the exhausr port of lower valve body is provided with noise silencer.Noise silencer reduces exhaust roar and pollutes, and improves product comfort level.
The beneficial effects of the utility model are: the utility model good looking appearance, and easy to process, reduced productive costs, reduced hidden danger of quality, production efficiency is high, has guaranteed car load lightweight, has certain promotional value.
