Abstract
The utility model provides an unloading gear for directly carrying out unloading, which is characterized in that a lining is arranged in a valve body; the lining and a valve core are provided with two contact faces which have the functions of a valve through the corresponding rectilinear motion; the open and close of an unload valve are the connection and separation of the two contact faces. The utility model has the advantages of simple structure, high reliability. The action is sensitive; the space in an air compressor doesn't be occupied; the installation is easy; the utility model is suitable for two kinds of air compressors with a reed valve or a hole valve.
Description
The utility model relates to a kind of unloading valve, particularly a kind of automobile-used air compressor unloading valve.
Present automobile-used air compressor unloading valve, its unloading way is the indirectly-acting off-load, and promptly high-pressure air enters the off-load valve body and acts on the spool top, makes the motion of spool push rod so that the suction valve chip on the air-breathing valve seat of promotion air compressor, air-breathing valve pocket is communicated with cylinder, thereby reaches the off-load purpose.This unloading valve structure is complicated, moves morely, and only is applicable to ports valve formula air compressor.
The purpose of this utility model is to avoid the above-mentioned deficiency of prior art and the unloading valve that proposes the direct off-load of a kind of energy, and it is simple in structure, be active in one's movements, reliably, and all applicable to Reed Valve and two kinds of air compressors of ports valve.
The purpose of this utility model is reached by following measure: unloading valve is contained on the cylinder cap of air compressor, and connects with exhaust chamber.Be provided with a lining in the unloading valve, lining and spool have such two surface of contact, thereby its straight line motion to axial by lining and spool can be closed or separates the effect of playing a valve.When high-pressure air enters the off-load valve body and acts on the spool top, spool will make spool separate with lining two surface of contact with respect to the downward axial linear movement of lining, i.e. valve open, and at this moment, air compressor exhaust chamber and atmosphere are connected, thereby reach the off-load purpose.
Two surface of contact that unloading valve neck bush and spool play the valve effect can be taper, flat shape or curved.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the longitudinal sectional drawing that the utility model is used for the Reed Valve air compressor.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Pipe joint (1), packing ring (2), (5), (8), valve body (3), spool (4), lining (6), spring (7), hexagonal socket nut (9), cylinder cap (10), exhaust chamber (11), through hole (12), attaching nut (13).Give the gas cylinder aeration phase at air compressor, unloading valve is a closed state, and promptly spool (4) contacts with lining (6) two conical surfaces.When the gas cylinder internal pressure surpasses the authorized pressure CLV ceiling limit value, to have high-pressure air to pass through pipe joint (1) enters valve body (3) and acts on spool (4) top, overcome the power of spring (7) and the pressure of exhaust chamber (11), spool (4) is the downward axial linear movement of lining (6) relatively, at this moment, spool (4) separates with lining (6) two conical surfaces, thereby exhaust chamber (11) reaches the off-load purpose just by through hole (12) and atmosphere connection.Upper half part of spool (4) contacts with its cylinder with upper half part of lining (6), and has tightness, thus can guarantee that high-pressure air acts on spool (4) top the time, spool (4) can be rapidly relatively lining (6) move downward.
The utility model is simple in structure, be active in one's movements, reliably, do not take space in the air compressor machine, and more easily install, applicability is wider.
Claims (4)
1, a kind of automobile-used air compressor unloading valve, valve body neck bush and the spool of being characterised in that of the present utility model has such two surface of contact, and its straight line motion to axial by lining and spool can be closed or separates, thereby plays the effect of a valve.
2, relief arrangement according to claim 1 is characterized in that lining and spool have two conical contact faces.
3, relief arrangement according to claim 1 is characterized in that lining and spool have two flat shape surface of contact.
4, relief arrangement according to claim 1 is characterized in that lining and spool have two curvilinerar figure surface of contact.
