Abstract
The utility model discloses a control valve used in automobile gas path, including a valve body, a valve cover and a valve core. In the cavity formed by the valve body and the valve cover provides a copper sheathing. In the right side of the valve body has an air inlet, relative to which on the other side has a gas outlet. On the top at the some side with the inlet has an air vent. On the valve cover provides a control mouth. Below the valve core arranges a return spring extended out the core. The utility model compared with technology at present has the advantages as follows: 1.simple Structure and easy operation; 2. good performance in stability and reliability, and less pressure loss; 3.convenient disassembly, assembly, maintenance and repair. The utility model is suitable for any gas path control switch in automobile.
Description
Technical field
The utility model relates to the control valve field, relates in particular to the control valve that a kind of automobile gas circuit is used.
Background technique
Gas path control valve is the vitals in the Automobile air way control switch, its type is varied, in order to guarantee its stable and reliability, its structure of existing control valve is more complicated mostly, thereby make the very big inconvenience that the control valve dismounting is safeguarded and maintained, and the local damage of control valve causes very easily that all the overall performance of control valve descends, and influences traffic safety.
Summary of the invention
The purpose of this utility model provides automobile gas path control valve a kind of simple in structure, easy to operate, stable and reliable for performance.
To achieve these goals, the utility model adopts following technological scheme: the automobile gas path control valve, comprise valve body, valve gap and spool, right side, described valve body bottom is provided with suction port, the opposite side corresponding with suction port is provided with the air outlet, is provided with relief opening with suction port with upper lateral part, and described valve gap top is provided with the control mouth, be provided with copper sheathing being positioned at the cavity that valve body and valve gap form, the below of described spool is provided with return spring.
The utility model compared with prior art, have the following advantages: when control mouthful feeds greater than specified air pressure, spool is just to moving down, blocked the circulation between the air inlet/outlet, the air pressure of air outlet is just given vent to anger from relief opening simultaneously, after the air pressure of control mouth is cancelled, spool moves up under the effect of return spring, make spool get back to original position, this moment, air inlet/outlet communicated, and air outlet and relief opening disconnect, its structure is very simple, operate also very convenient flexibly, this simple structure has also avoided local parts more and the deficiency that breaks down has easily increased its stability and reliability, the pressure loss is also smaller, and easy accessibility is convenient to M R, and the utility model is applicable to all kinds of Automobile air way control switch.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model automobile gas path control valve.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1: the utility model comprises valve body 1, valve gap 2 and spool 3, be provided with copper sheathing 4 being positioned at the cavity that valve body 1 and valve gap 2 formed, right side, described valve body 1 bottom is provided with suction port 11, opposite side with respect to suction port 11 is provided with air outlet 12, is provided with relief opening 13 with suction port 11 with upper lateral part.The below of described spool 3 is provided with return spring 31, and described valve gap 2 tops are provided with control mouth 21.When suction port 11 feeds air pressure, air outlet 12 just goes out identical air pressure, when control mouthfuls 21 fed air pressure greater than 0.3MPa, spool 3 had blocked the circulation between the air inlet/outlet just to moving down, the air pressure of air outlet 12 is just given vent to anger from relief opening 13 simultaneously, after the air pressure of control mouth 21 was cancelled, spool 3 moved up under the effect of return spring 31, makes spool 3 get back to original position, this moment, air inlet/outlet communicated, and air outlet 12 and relief opening 13 disconnect.The utility model has been simplified the internal structure of traditional control valve greatly, and is applicable to all kinds of Automobile air way control switch.
