Abstract
The invention discloses a high-degree integration air inlet control valve of a screw air compressor, which comprises an air inlet valve, a solenoid valve and a discharge valve, wherein the solenoid valve and the discharge valve are both installed on the air inlet valve; the discharge valve is provided with an outward discharge port and an inward discharge port; the outward discharge port on the discharge valve is communicated with the upper part of the air inlet valve via a discharge channel in front of a valve; the inward discharge port on the discharge valve is communicated with the lower part of the air inlet valve via a discharge channel at the back of the valve; the solenoid valve and the discharge valve are respectively provided with an air outlet and a loading and unloading control port; the air outlet of the solenoid valve is communicated with the air outlet on the discharge valve; the air outlet on the discharge valve is communicated with the upper part of the air inlet valve via an air outlet channel of the solenoid valve; the loading and unloading control port of the solenoid valve is communicated with the control port of the discharge valve; the loading and unloading control port of the discharge valve is communicated with a piston cavity via a loading and unloading control channel; the piston cavity is arranged in the solenoid valve; and the discharge channel in front of a valve, the =discharge channel at the back of the valve, the air outlet channel of the solenoid valve and the loading and unloading control channel are all arranged in the air inlet control valve. According to the high-degree integration air inlet control valve of the screw air compressor, an external pipeline of the original air inlet control valve is omitted, all function channels are completely integrated in the air inlet control valve, leakage points are reduced, and the cost is greatly lowered.
Description
Technical field
the present invention relates to the highly integrated screw air compressor air intake control valve of one.
Background technology
general screw air compressor air intake control valve is made up of intake valve, bleeder valve, magnetic valve etc., they are installed on different positions, connected by pipeline, or bleeder valve and magnetic valve are arranged on intake valve, the pipeline of releasing of bleeder valve is connected by tracheae with the gas exhaust piping of magnetic valve, because the volume of intake valve is little, so very inconvenient when connecting bleeder valve and electromagnetic valve pipeline, consider easy for installation, be difficult to accomplish desirable effect, pipeline more in addition easily leaks, and too much pipeline adds cost.
Summary of the invention
the object of the invention is to overcome above deficiency, providing the height that a kind of structure is simple, cost is low integrated screw air compressor air intake control valve.
object of the present invention is achieved through the following technical solutions: the highly integrated screw air compressor air intake control valve of one, comprise intake valve, magnetic valve and bleeder valve, described magnetic valve and bleeder valve are installed on intake valve, described magnetic valve is located at above described bleeder valve, described bleeder valve is arranged on bottom, described intake valve outer face, described bleeder valve is provided with external bleed outlet and internal bleed outlet, external bleed outlet on described bleeder valve is communicated with the top of intake valve by leakage path before valve, internal bleed outlet on described bleeder valve is communicated with the bottom of intake valve by leakage path after valve, described magnetic valve and bleeder valve are provided with exhaust outlet and add Unloading Control mouth, the exhaust outlet of described magnetic valve communicates with the exhaust outlet on described bleeder valve, exhaust outlet on described bleeder valve is communicated with the top of intake valve by solenoid valve vents passage, the Unloading Control mouth that adds of described magnetic valve communicates with the control mouth of bleeder valve, the Unloading Control mouth that adds of described bleeder valve communicates with plunger shaft by adding Unloading Control passage, described plunger shaft is located in magnetic valve, leakage path before described valve, leakage path after valve, solenoid valve vents passage and add Unloading Control passage and be all located at air intake control valve inside.
the present invention has the following advantages: the pipeline eliminating former air intake control valve outside, all functions passage is all integrated in air intake control valve inside, i.e. leakage path, solenoid valve vents passage and add Unloading Control passage and be all located at air intake control valve inside after leakage path, valve before valve, decrease leakage point, and cost reduces greatly.
accompanying drawing illustrates:
