Abstract
The utility model discloses an unloading one-way valve which is used for an air compressor, in particular to an air compressor driven by a diesel engine, etc. The unloading one-way valve comprises a valve body which is provided with an air inlet chamber and an air outlet chamber, and the side wall of the valve body at the combining position of the air inlet chamber and the air outlet chamber is provided with a valve element. The valve body is provided with an air pressure regulating valve assembly, and a valve body is corresponding to the air pressure regulating valve assembly and is provided with an exhaust hole. The lower end of the air pressure regulating valve assembly is communicated with the inner cavity body of the valve body. The unloading one-way valve can release pressure in time when the air pressure of the air storage cylinder of an air compressor achieves the specified value, and the unloading one-way valve is especially suitable for air compressors which can not be controlled to be closed and stopped at any time, and the air compressors are driven by diesel engines, electric motors with high power, etc.
Description
The utility model relates to a kind of engineering element or parts, specifically, is the one-way valve of a kind of energy off-load; The utility model also relates to elastic fluid pump, is a kind of parts of the elastic fluid pump that is used for compressing.
One-way valve is parts essential on the air compressor, although people set out in all its bearings, one-way valve many improvement have been carried out, but air compressor for drivings such as diesel engine and heavy-duty motors, these one-way valves still are difficult to adapt to, because diesel engine etc. can not resemble the low-power machine start-stop at any time, thereby when having to turn off diesel engine when air pressure overrate in the air compressor gas receiver, make troubles just for startup once more subsequently, though, on some air compressors, adorned pressure relief valve and decompressor, but complex structure has brought problem to maintenance.
The purpose of this utility model provides and a kind ofly not only can play common one-way valve effect, and can play the unloading one-way valve of off-load effect.
Technical solution of the present utility model is: a kind of unloading one-way valve, comprise valve body, air-inlet cavity and outlet chamber are arranged in the valve body, on the body wall of air-inlet cavity and outlet chamber intersection, the valve element is housed, the difference of itself and prior art is: the air pressure adjustment valve assembly is housed on the valve body, have exhaust port on the valve body corresponding with the air pressure adjustment valve assembly, air pressure adjustment valve assembly lower end communicates with the body cavity body.
Adorned in the utility model on the valve body of air pressure adjustment valve assembly and had vent rib or fin.Certainly, vent rib and fin also can or replace other suitable construction under suitable situation.
The cavity that communicates with the air pressure adjustment valve assembly in the utility model is an air-inlet cavity.What certainly, communicate with it also can be other proper site.
Exhaust port in the utility model on the valve body is equipped with silencer outward.Certainly, also can not adorn silencer.
Silencer in the utility model comprises the lid with the valve body bolt, covers to have a plurality of apertures, and sponge is housed in the lid.Certainly, silencer also can adopt other suitable structural types.
Air pressure adjustment valve assembly in the utility model comprise retaining the valve block that communicates with the body cavity body, behind the valve block spring, and spring after adjusting nut, adjusting nut and valve body bolt.Certainly, air pressure regulator also can adopt other suitable structural types.
Upper and lower spring seat is housed respectively before and after the spring in the utility model.Certainly, also can adopt other suitable construction forms.
The utility model has the advantages that: simple in structure, easy to use, usefulness more than one helps to improve performance of air compressor and reduces cost.Not only can play well behaved one-way valve effect, especially can timely release when air compressor gas receiver air pressure reaches specified value, be specially adapted to the air compressor that drives by diesel engine and heavy-duty motor etc. of start-stop at any time.Noise when the silencer that the utility model adopts not only can effectively reduce the off-load venting, and structure is very simple, and cost is very low.Strengthened the performance of valve greatly, reduced noise pollution environment.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is the structural representation of a kind of unloading one-way valve of the present utility model.
Accompanying drawing has been described an embodiment of the present utility model.In casting valve body 1 one sides that have vent rib is suction port 11, on the valve wall relative the valve element that is made of check valve sheet 4, unidirectional valve gap 3, unidirectional valve spring etc. is housed with suction port 11, in valve body 1 lower end is air outlet 12, is equipped with in valve body 1 upper end by regulating valve block 5, lower spring cup 6, regulating the air pressure regulator element that spring 7, upper spring seat 8, adjusting nut 9 etc. are formed.On the valve body 1 relative, have exhaust port, be equipped with on the exhaust port by noise reduction lid 13 with the modulating valve element, the silencer that noise reduction sponge etc. are formed, noise reduction covers and has several apertures 10.
Present embodiment backs down one-way valve element in use after pressurized air enters valve body by suction port; Enter the air compressor gas receiver by the air outlet, when air pressure reached rating value in the gas receiver, air-flow backed down the modulating valve element on valve body top, and air-flow enters atmosphere by exhaust port through silencer, reaches timely off-load purpose.
The utility model also can install handle additional on adjusting nut 9, for opening when air compressor starts, have the off-load effect, reduces the easier starting of starting current, particularly Diesel Driven, can close after compressor runs well.Certainly, also can be before any position of valve body air-inlet cavity installs a startup separately additional the off-load switch, can guarantee zero load startup equally.
