Abstract
The invention relates to an automobile vacuum tube assembly with a built-in one-way valve. A plastic cylindrical one-way valve is arranged in the tube assembly in the required direction; the tube assembly is directly connected with a vacuum booster; and the plastic one-way valve (2) is arranged in a rubber hose (1), and the vacuum tube assembly with the one-way valve is inserted into a connection port of the vacuum booster (3). The tube assembly can transmit gas in one direction; the size of a cylinder of the one-way valve is in interference fit with the internal diameter of a vacuum hose; and the price of the plastic one-way valve in China is about 3 yuan, the price of the plastic one-way valve in foreign countries is about 6 yuan, and the price of a metal one-way valve is more than 10 yuan, so that the cost of the tube assembly is reduced. The vacuum tube assembly with the built-in one-way valve is convenient to install, and efficiency is improved by over 70 percent when the vacuum tube assembly is in assembly connection with the vacuum booster.
Description
Technical field
The present invention relates to automotive hose function design field, particularly a kind of vacuum automobile pipe pipeline assembly with built-in check valve.
Background technology
The power that acts in the braking automobile process on the brake facing need be produced by the force urges hydraulic actuating cylinder that the auxiliary people's pin of vacuum booster applies.The vacuum of vacuum booster is taken from the air system of driving engine, is connected to vacuum booster by vacuum lamp.People do not hope that the engine stop working brake is just malfunctioning, so the function of automatic maintenance vacuum state should be arranged in this system.Early stage design is at the interface of vacuum booster and vacuum lamp a check valve to be installed, and this check valve can realize that gas unidirectional circulates to the driving engine direction.When engine operation, one-way valve opens, gas gets into air system by vacuum booster, is vacuum state in the vacuum booster; When engine stop working, closed check valve, gas can not oppositely get into vacuum booster from air system, and the vacuum state that is about in the servo-unit keeps.Reached and keep in any case being the effect of vacuum state in the vacuum booster, for brake facing provides stable brake weight.Yet the check valve of the vacuum booster that uses is because will be installed on the servo-unit metal shell at present; As shown in Figure 1; Material and connectivity to check valve have all proposed exacting requirements, and the first, the metal shell of check valve is threaded with the vacuum booster housing need do encapsulation process; The second, quality is heavy, complex manufacturing technology, and waste is serious.
Summary of the invention
The present invention is used to solve above-mentioned prior art problem and provides a kind of functional identical with original design, and is simple in structure, production efficiency is high, cooperate to be easy to the pipeline assembly.
Vacuum lamp assembly of the present invention solves through following technical scheme:
A kind of vacuum automobile pipe pipeline assembly of the present invention with built-in check valve; The check valve of plastic cylinder shape has been installed in its inside of pipeline assembly, and check valve is that on request direction is installed in pipeline, and this pipeline assembly directly is connected with vacuum booster.
The pipeline assembly of check valve of the present invention in pipeline can be realized the one-way of air-flow, and air-flow can only flow to the other end through check valve from an end of regulation, but can not circulate by reversing sense, keeps the vacuum state of vacuum booster.
As shown in Figure 2, One-way Plastic Valves (2) is assembled in the rubber tube (1), the vacuum line assembly that will assemble check valve then is inserted in the communication port place of vacuum booster (3), and this pipeline assembly has air-transmitting one-way; Check valve cylinder dimensions and vacuum hose internal diameter size are interference fit.
The check valve of plastic cylinder shape has been installed in its inside of pipeline assembly of the present invention, and check valve is that on request direction is installed in pipeline, and this pipeline assembly directly is connected with vacuum booster, and encapsulation process need not done in the junction.
The pipeline assembly of check valve in the pipeline characteristic for the one-way flow that realizes air-flow has been installed, has been printed on the air flow line sign in pipeline assembly outside, avoided plastic cylinder shape check valve counter adorn the back air-flow can not one-way flow.
The present invention is simple in structure, be easy to realize, because this pipeline assembly is positioned at the automotive engine brake system, belongs to safety member, so the pipeline performance need satisfies the GB/T16897 standard-required.Vacuum lamp internal diameter size specification limit is 7.5mm～10mm, as long as plastic cylinder shape check valve meets the requirements, at home and abroad manufacturer production can use.
