Abstract
The utility model discloses an automobile pneumatic brake control electromagnetic valve with three single valves. The automobile pneumatic brake control electromagnetic valve with the three single valves comprises a valve body and a plug-in connector, wherein the valve body comprises a valve body base which is provided with an air inlet; the three single valves are arranged on the valve body base and are correspondingly connected with air outlets; each single valve is provided with a live wire amphenol connector and a null line amphenol connector; the three live wire amphenol connectors are connected with live wires respectively; the three live wires are connected to the corresponding interface ends of the plug-in connector respectively; the three null line amphenol connectors are connected in series and then are connected with two null lines; the two null lines are connected to the corresponding interface ends of the plug-in connector. The service life of the electromagnetic valve with the three single valves is prolonged greatly, the refund rate of after-sales service is reduced, the problem that an electromagnetic valve with three single valves loses efficacy due to poor contact of a null line when only one null line is provided is solved effectively, and the electromagnetic valve wins praise from the majority of users.
Description
Technical field
The utility model relates to a kind of automobile air brake control setup, relates in particular to a kind of automobile air brake control triplet electromagnetic valve.
Background technology
In prior art, triplet electromagnetic valve is to be connected in automobile air brake pipeline, for controlling the high low speed of automobile, energy brake, air pressure horn and Vehicle tipping.As shown in Figure 3 and Figure 4, the triplet electromagnetic valve existing at present comprises three valve bodies 1 and connector 2, wherein, three live wires that comprise that are connected with plug wire device 2 corresponding interface end a ', interface end b ', interface end c ' and interface end d ' are live wire a, live wire b and live wire c and a zero line d.Connect because the connector 2 of triplet electromagnetic valve only has a zero line, in routine use, in the time of this root zero line d bad contact, can cause three valve bodies of triplet electromagnetic valve to lose efficacy, and then affect automobile brake.Return product data analysis according to three guarantees, the rate of returning of triplet electromagnetic valve is 3% in half a year, and this 3% returns in product, the product of returning because of zero line bad contact accounts for 95%.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of consistent, long service life, reduced three guarantees returns the automobile air brake control triplet electromagnetic valve of rate.
For solving the problems of the technologies described above, the technical solution of the utility model is: automobile air brake control triplet electromagnetic valve, comprise three valve bodies and connector, described three valve bodies comprise valve block, described valve block is provided with admission port, described valve block is provided with three monomer valve, three described monomer valve correspondences are connected with air extractor duct, in each monomer valve, be respectively equipped with hot terminal and zero line connection terminal, three described hot terminal are connected with respectively live wire, three described live wires are connected respectively to described connector corresponding interface end, after being serially connected, three described zero line connection terminals are connected with two zero lines, two described zero lines are received respectively described connector corresponding interface end.
As preferred technical scheme, three described live wires outward respectively parcel be provided with yellowish-white, reddish yellow, yellowish green outer tube.
As the improvement to technique scheme, two described zero line outer wrapping are provided with the outer tube of black
Owing to having adopted technique scheme, automobile air brake control triplet electromagnetic valve, comprise three valve bodies and connector, described three valve bodies comprise valve block, described valve block is provided with admission port, described valve block is provided with three monomer valve, three described monomer valve correspondences are connected with air extractor duct, in each monomer valve, be respectively equipped with hot terminal and zero line connection terminal, three described hot terminal are connected with respectively live wire, three described live wires are connected respectively to described connector corresponding interface end, after being serially connected, three described zero line connection terminals are connected with two zero lines, two described zero lines are received respectively described connector corresponding interface end.The utility model is connected in automobile air brake pipeline, initial condition, and admission port is connected with air receiver all the time, and three air extractor ducts are all closed; When pressing associated button switch, corresponding air extractor duct is opened, and output pressure, is respectively used to control the high low speed of automobile, energy brake, air pressure horn and Vehicle tipping; When release button switch, air extractor duct is closed, and the gas in pipeline is discharged through exhausr port.Owing to using two described zero lines to be connected with described connector corresponding interface end, even if a so wherein described zero line bad contact also has a described zero line can ensure normal use, can not affect the normal use of triplet electromagnetic valve.The utility model has improved the service life of triplet electromagnetic valve greatly, has reduced three guarantees and has return rate, when actv. has solved a zero line, because of the triplet electromagnetic valve Problem of Failure that zero line bad contact causes, has obtained users' consistent favorable comment.
