Description
Technical field:
The present invention relates to the air compressor accessory, is a kind of for matching used combined pressure regulating valve on the air compressor.
Background technique:
Air compressor is an a kind of purposes standard equipment very widely, can both see its trace in all trades and professions, is bringing into play important effect in national economy.Existing air compressor is structurally similar, and is especially also basic identical on accessory, and as diesel-driven air compressor or motor-driven air compressor more than the 11KW, employing has the one-way valve of off-load effect substantially at present.But these discharging type one-way valve structures are still comparatively complicated, used components and parts are more, cost is also higher relatively, and more fragile, working life is also not ideal enough, and sealing is poor, drag losses is big, particularly because the exhaust airstream of piston type air compressor is pulsed, the spool of one-way valve is patted with the potted line generation high frequency of one-way valve under the effect of pulsing airflow, and spool very easily damages
Summary of the invention:
The purpose of this invention is to provide that a kind of drag losses is little, work is sensitive, sealing is reliable, it is effective that resistance to high temperature is good, long service life, off-load emptying are eliminated the noise, the tangible combined pressure regulating valve of energy-saving effect.
Technical solution of the present invention is: a kind of combined pressure regulating valve, the upper valve body and the following valve body that are connected are arranged, following body wall has intake interface, the lower end of following valve body has and the gas receiver connection mouth, it is characterized in that: with have one to be communicated with suction port in the gas receiver connection mouth end valve body, be communicated with the suction port top two sides sealed valve core is housed, sealed valve core top, two sides is the unloading cavity suction port, above being arranged in the unloading cavity of upper valve body the off-load spool chamber is arranged, the off-load spool is housed in the chamber, off-load spool lower end and two sides sealed valve core join, off-load valve pocket air outlet is connected with a valve body integrated type noise elimination mechanism, the upper valve body upper end is connected with the pressure regulator valve suction port, and following valve body has gas receiver pressure drawing-off mouth to be connected with the pressure regulator valve suction port by the road.
Have in the valve body integrated type noise elimination mechanism described in the present invention with above and/or under the noise elimination housing of valve body integrally casting moulding, under the noise elimination housing air outlet is arranged, in the noise elimination housing hush tube is housed.The two sides sealed valve core is a valve plate, and valve plate is equipped with spring with being communicated with between suction port.Soft work valve block is all adorned in the both sides of valve plate.The off-load spool is a labyrinth piston bar, and the labyrinth piston bar is loaded in the interior piston sleeve of off-load valve pocket, between piston sleeve and labyrinth piston bar spring is housed.
Beneficial effect of the present invention is: the novel structure uniqueness, simplicity of design is reasonable, drag losses is little, the sealing of unloading valve work sensitivity, one-way valve is reliable, has improved resistance to high temperature, long service life, off-load emptying and has eliminated the noise effectively, and energy-saving effect is remarkable.
The present invention is further illustrated below in conjunction with drawings and Examples:
Description of drawings:
Fig. 1 is the structural representation of a kind of combined pressure regulating valve of the present invention;
Fig. 2 is the side view of Fig. 1.
Embodiment:
Fig. 1, Fig. 2 have described one embodiment of the present of invention jointly.The upper valve body 1 and the following valve body 2 that are connected are arranged in this embodiment, following valve body 2 sidewalls have intake interface 3, the lower end of following valve body 2 has and gas receiver connection mouth 4, with have one to be communicated with suction port 5 in the gas receiver connection mouth end valve body, be communicated with suction port 5 tops two sides sealed valve core 6 is housed, sealed valve core 6 tops in two sides are unloading cavity suction port 7, above being arranged in the unloading cavity of upper valve body 1 the off-load spool chamber is arranged, off-load spool 8 is housed in the chamber, off-load spool 8 lower ends and two sides sealed valve core 6 join, off-load valve pocket air outlet is connected with a valve body integrated type noise elimination mechanism, upper valve body 1 upper end is connected with pressure regulator valve 9 suction ports, and following valve body 2 has gas receiver pressure drawing-off mouth 10 11 to be connected with pressure regulator valve 9 suction ports by the road.Have in the described valve body integrated type noise elimination mechanism with above and/or under the noise elimination housing 12 of valve body integrally casting moulding, the noise elimination housing has air outlet 13 12 times, and hush tube 14 or other silencer element are housed in the noise elimination housing 12.Two sides sealed valve core 6 is a valve plate, valve plate 6 be communicated with 5 of suction ports spring 19 be housed.Soft work valve block 15,16 is all adorned in the both sides of valve plate 6.Off-load spool 8 is a labyrinth piston bar, and labyrinth piston bar 8 is loaded in the interior piston sleeve 17 of off-load valve pocket, at piston sleeve 17 and 8 on labyrinth piston bar spring 18 is housed.
