Abstract
The utility model relates to a kind of screw-rod air compressor gas valve, comprise suction valve, bleeder valve and solenoid valve, in suction valve, be provided with air aspiration cavity, on bleeder valve, be provided with bleeder valve outlet, the air aspiration cavity of suction valve is connected with bleeder valve outlet by pipeline, in pipeline, be provided with nonreturn valve core, between pipeline and suction valve, be provided with seal ring, its optimum scheme is: between pipeline and suction valve, be provided with seal ring.The utlity model has rational in infrastructurely, performance is firm, long service life, and fabricating cost is low, and external tonifying Qi pipeline is reasonably integrated in to suction valve inside, has solved the problem of traffic-induced damage, has improved the outward appearance of suction valve, has reduced the advantage of leakage point.
Description
Technical field
The utility model relates to a kind of screw-rod air compressor gas valve.
Background technique
Suction valve is installed on screw air compressor suction end, utilize air-breathing throttling, just can realize the volume flow of adjusting screw rod air compressor, in the time that the shaft seal effect of exhaust end base of oil injection threaded bolt air compressor is relatively good, close suction valve completely, can make air aspiration cavity pressure be low to moderate the vacuum state below 40pa, in this case, due to cavitation effect, screw air compressing chance produces strong noise, for fear of the appearance of this phenomenon, there is the function of tonifying Qi so produce at present suction valve, close at suction valve, bleeder valve is opened, pressurized air by bleeder valve one road toward bleeder valve before valve, another road is toward air aspiration cavity tonifying Qi, reduce air aspiration cavity degree of vacuum, avoid screw air compressor to produce cavitation noise.
The suction valve of producing at present has gas compensation function, is to draw a pipeline from bleeder valve nylon tube or metal tube, an one-way valve is set on pipeline, then accesses air aspiration cavity tonifying Qi.External tonifying Qi pipeline has the problem of several respects, and one, affect suction valve outward appearance; Two, be easy in transit be broken; Three, joint is many easily produces and leaks; Four, cost is high.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, provides a kind of rational in infrastructure, and performance is firm, long service life, the screw-rod air compressor gas valve that fabricating cost is low.
The purpose of this utility model is achieved through the following technical solutions: a kind of screw-rod air compressor gas valve, comprise suction valve, bleeder valve and solenoid valve, in suction valve, be provided with air aspiration cavity, on bleeder valve, be provided with bleeder valve outlet, the air aspiration cavity of suction valve is connected with bleeder valve outlet by pipeline, in pipeline, be provided with nonreturn valve core, between pipeline and suction valve, be provided with seal ring.
The advantage that the utility model compared with prior art has is:
Rational in infrastructure, performance is firm, long service life, and fabricating cost is low, and external tonifying Qi pipeline is reasonably integrated in to suction valve inside, has solved the problem of traffic-induced damage, has improved the outward appearance of suction valve, has reduced leakage point, has saved cost.
brief description of the drawings:
Fig. 1 is the structural representation of a kind of mode of execution of the utility model;
Fig. 2 is the structural representation of the another kind of mode of execution of the utility model;
Fig. 3, Fig. 4 are the structural representation of existing suction valve;
Number in the figure: 1-suction valve, 2-bleeder valve, 3-solenoid valve, 4-air aspiration cavity, the outlet of 5-bleeder valve, 6-pipeline, 7-nonreturn valve core, 8-seal ring.
embodiment:
in order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1,2 shows a kind of mode of execution of a kind of screw-rod air compressor gas valve of the utility model: comprise suction valve 1, bleeder valve 2 and solenoid valve 3, in suction valve 1, be provided with air aspiration cavity 4, on bleeder valve 2, be provided with bleeder valve outlet 5, the air aspiration cavity 4 of suction valve 1 is connected with bleeder valve outlet 5 by pipeline 6, in pipeline 6, be provided with nonreturn valve core 7, between pipeline 6 and suction valve 1, be provided with seal ring 8.
The utility model is integrated in bleeder valve inside the one-way valve on former external pipeline, the entrance of one-way valve has just been communicated with bleeder valve outlet in inside, and the outlet of one-way valve is corresponding with the tonifying Qi hole on air inlet valve flange attachment face, by above improvement, the utility model is ensureing, under the prerequisite of original gas compensation function, external tonifying Qi pipeline to be reasonably integrated in to suction valve inside, solve the problem of traffic-induced damage, the outward appearance of having improved suction valve, has reduced leakage point, has saved cost.
