Abstract

The utility model relates to a highly integrated air inlet control valve of a screw air compressor. The highly integrated air inlet control valve comprises an air inlet valve, an electromagnetic valve and a release valve, wherein the electromagnetic valve and the release valve are arranged on the air inlet valve; an outward release outlet and an inward release outlet are formed on the release valve; the outward release outlet on the release valve is communicated with the upper part of the air inlet valve through a release passage in front of the release valve; the inward release outlet on the release valve is communicated with the lower part of the air inlet valve through a release passage behind the release valve; an air outlet and a loading and unloading control port are formed on each of the electromagnetic valve and the release valve; the air outlet of the electromagnetic valve is communicated with the air outlet of the release valve; the air outlet of the release valve is communicated with the upper part of the air inlet valve through an exhaust passage of the electromagnetic valve; the loading and unloading control port of the electromagnetic valve is communicated with the control port of the release valve; the loading and unloading control port of the release valve is communicated with a piston cavity through a loading and unloading control passage; the piston cavity is arranged in the electromagnetic valve; and the release passage in front of the release valve, the release passage behind the release valve, the exhaust passage of the electromagnetic valve and the loading and unloading control passage are arranged in the air inlet control valve. The highly integrated air inlet control valve has the advantages that a pipeline outside the original air inlet control valve is removed, all the functional passages are integrated in the air inlet control valve, leakage points are reduced, the cost is greatly lowered, and the like.

Description

The integrated screw air compressor air intake control valve of a kind of height

Technical field

The utility model relates to the integrated screw air compressor air intake control valve of a kind of height

Background technique

General screw air compressor air intake control valve is comprised of suction valve, bleeder valve, solenoid valve etc., they are installed on different positions, connect by pipeline, or bleeder valve and solenoid valve be installed on the suction valve, the pipeline of releasing of bleeder valve is connected gas exhaust piping and is connected by tracheae with solenoid valve, because the volume of suction valve is little, so very inconvenient when connecting bleeder valve and electromagnetic valve pipeline, consider easy for installation, be difficult to accomplish desirable effect, more pipeline leaks easily in addition, and too much pipeline has increased cost

Summary of the invention

The purpose of this utility model is in order to overcome above deficiency, to provide a kind of height simple in structure, that cost is low integrated screw air compressor air intake control valve.

The purpose of this utility model is achieved through the following technical solutions: the integrated screw air compressor air intake control valve of a kind of height, comprise suction valve, solenoid valve and bleeder valve, described solenoid valve and bleeder valve are installed on the suction valve, described solenoid valve is located at described bleeder valve top, described bleeder valve is installed in bottom, described suction valve exterior edge face, described bleeder valve is provided with external bleed outlet and internal bleed outlet, external bleed outlet on the described bleeder valve by valve before leakage path communicate with the top of suction valve, internal bleed outlet on the described bleeder valve by valve after leakage path communicate with the bottom of suction valve, described solenoid valve and bleeder valve are provided with relief opening and add the Unloading Control mouth, the relief opening of described solenoid valve communicates with relief opening on the described bleeder valve, relief opening on the described bleeder valve communicates with the top of suction valve by the solenoid valve exhaust passage, the Unloading Control mouth that adds of described solenoid valve communicates with the control mouth of bleeder valve, the Unloading Control mouth that adds of described bleeder valve communicates with piston cavity by adding the Unloading Control passage, described piston cavity is located in the solenoid valve, leakage path before the described valve, leakage path behind the valve, solenoid valve exhaust passage and add the Unloading Control passage and all be located at air intake control valve inside.

The utlity model has following advantage: the pipeline of having cancelled former air intake control valve outside, the all functions passage all is integrated in air intake control valve inside, be leakage path, solenoid valve exhaust passage and add the Unloading Control passage and all be located at air intake control valve inside behind leakage path before the valve, the valve, reduced leakage point, and cost reduces greatly.

Description of drawings:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the sectional view of A-A;

Fig. 3 is the sectional view of B-B;

Number in the figure: leakage path, 6-solenoid valve exhaust passage, 7-add the Unloading Control passage behind 1-suction valve, 2-solenoid valve, 3-bleeder valve, the front leakage path of 4-valve, the 5-valve.

Embodiment:

In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
