Abstract
The utility model relates to a movable air intake control valve of a screw air compressor. The movable air intake control valve comprises an intake valve, the intake valve is connected with a stop discharge valve and a gulp valve through pipelines, the stop discharge valve is connected with the gulp valve through a pipeline, and a pressure regulating valve is arranged on the stop discharge valve. The movable air intake control valve provided by the utility model integrates the intake valve, the pressure control valve, the discharge valve and the gulp valve; a semi-normally open structure is adopted on the intake valve, so that the closing speed is fast and the starting load is small; the direct proportional pressure regulating valve is accurate in pressure control; and the gulp valve can be used for reducing the vacuum degree of an air suction chamber and eliminating the unloading noise.
Description
Technical field
The utility model relates to the parts that use on the movable screw air compressor in mechanical technique, specifically a kind of movable screw air compressor air intake control valve.
Background technique
The movable screw air compressor of selling in the market generally all adopts normally closed suction valve; externally install again the inverse proportion pressure regulator valve additional; and bleeder valve; between them, by pipeline, connect; main shortcoming is movable screw air compressor because rear end does not have gas holder; only has terminal equipment; air compressor rear end volume is smaller; during use, in a single day terminal equipment is stopped using; air compressor rear end pressure rise is very fast; and that normally closed suction valve cuts out speed is relatively slow, so often there will be the situation of washing safety valve open, certain potential safety hazard is arranged.Because each controls valve member dispersion installation, the connecting pipeline complexity, easily produce and leak in addition, and pressure control is also unstable.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, provides a kind of and closes rapidly, starts the movable screw air compressor air intake control valve that load is little, pressure control is stable, unloaded noise is low.
The purpose of this utility model is achieved through the following technical solutions: a kind of movable screw air compressor air intake control valve; comprise suction valve; suction valve is connected with and shuts down bleeder valve and aeration valve by pipeline; shut down between bleeder valve and aeration valve and be connected by pipeline, shut down bleeder valve and be provided with pressure regulator valve.
The utility model compared with prior art has the following advantages: the utility model collection suction valve, pressure controlled valve, bleeder valve, aeration valve one; Suction valve adopts half structure open in usual, and closing velocity is fast, starts load little; Direct proportaion pressure regulator valve pressure is controlled precisely; Aeration valve can reduce air aspiration cavity degree of vacuum, eliminates the unloading noise.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A to structural representation;
Number in the figure: 1-suction valve, 2-shut down bleeder valve, 3-aeration valve, 4-pressure regulator valve.
Embodiment:
Feature of the present utility model can be used for vertical structure, also can be for horizontal structure or leaning structure form.
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, be used to explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 and Fig. 2, show a kind of mode of execution of the utility model movable screw air compressor air intake control valve; comprise suction valve 1; suction valve 1 is connected with and shuts down bleeder valve 2 and aeration valve 3 by pipeline; shut down between bleeder valve 2 and aeration valve 3 and be connected by pipeline, shut down bleeder valve 2 and be provided with pressure regulator valve 4.
The utility model collection suction valve, pressure controlled valve, bleeder valve, aeration valve one; Suction valve adopts half structure open in usual, and closing velocity is fast, starts load little; Direct proportaion pressure regulator valve pressure is controlled precisely; Aeration valve can reduce air aspiration cavity degree of vacuum, eliminates the unloading noise.
