The utility model discloses when the piston descends, cushion through the check spring to collision in -process at the piston plays the cushioning effect, promotes pressure control valve's life. The utility model provides a pressure control valve simple structure not only is applicable to the air compressor of different specifications, and ensures that the compressed air in the air compressor could discharge when certain pressure value is above.
Description
Technical field
The utility model relates to a kind of pressure controlled valve, particularly a kind of pressure controlled valve for air compressor.
Background technique
Pressure controlled valve is by the forced under pressure piston of gas and after Exhaust Gas, piston can be pushed into rapidly the position of bounding means by the minimizing along with gas pressure, now, because the reaction force lower piston of Compress Spring can be badly damaged in collision process, the working life affecting pressure controlled valve is caused.
At present, the complex structure of pressure controlled valve, especially to the pressure controlled valve for air compressor, should guarantee could discharge when pressurized air in air compressor is more than certain force value, protect all parts in pressure controlled valve again.Therefore, pressure controlled valve parts to buffer function is needed.
Model utility content
The technical problems to be solved in the utility model does not have buffer function in order to overcome pressure controlled valve in prior art to parts such as pistons, causes the defect in the working life affecting pressure controlled valve, provide a kind of pressure controlled valve.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of pressure controlled valve, described pressure controlled valve comprises valve body, valve gap, piston, suction port, air outlet, unlatching spring, safety check assembly and check spring, described valve gap is arranged on described valve body, described piston is arranged in described valve body, be connected described unlatching spring between described piston with described valve gap, described safety check assembly is connected described check spring with between described piston.
Preferably, described safety check assembly comprises sleeve and disc, and described sleeve is fixedly installed on described disc, and described check spring is sheathed in described sleeve, and described jacket casing is located in described piston.
Preferably, described sleeve is fixedly installed on described disc by packing ring and bolt.
Preferably, described valve gap is arranged on described valve body by screw thread.
Preferably, described pressure controlled valve also comprises O type circle, and described O type circle is arranged on the groove of the outer surface of described piston.
In this programme, described O type circle is used for sealing under the motion state of described piston.
Preferably, described piston laminating is arranged at the inwall of described valve body.
Preferably, Seal cage is formed between described valve gap and described piston.
Preferably, the limited part of described safety check assembly on the inwall being located at described valve body.
Preferably, described limited part in the form of a ring.
Preferably, one end of described suction port and one end of described air outlet all arrange screw thread.
In this programme, screw thread is set to connect different outer tube, thus is applicable to the air compressor of different size.
On the basis meeting related domain general knowledge, above-mentioned each optimum condition, can combination in any, obtains each preferred embodiments of the utility model.
Positive progressive effect of the present utility model is:
The utility model, when piston declines, is cushioned by check spring, thus plays cushioning effect in the collision process of piston, the working life of adherence pressure control valve.The Stress control valve arrangement that the utility model provides is simple, is not only applicable to the air compressor of different size, and guarantees could discharge when pressurized air in air compressor is more than certain force value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pressure controlled valve of the utility model preferred embodiment.
Fig. 2 is the stereogram of the pressure controlled valve of the utility model preferred embodiment.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As shown in Figures 1 and 2, the pressure controlled valve of the utility model one preferred embodiment comprises valve body 1, valve gap 2, opens spring 3, piston 4, O type circle 5, check spring 6, safety check assembly, suction port 10 and air outlet 11, and described safety check assembly comprises sleeve 7, disc 8, packing ring, lock washer and bolt;
Described valve gap 2 is arranged on described valve body 1 by screw thread, described piston 4 laminating is arranged at the inwall of described valve body 1, be connected described unlatching spring 3 between described piston 4 with described valve gap 2 and form Seal cage, described O type circle 5 is arranged on the groove of the outer surface of described piston 4, described O type circle 5 for sealing under the motion state of described piston 4, described check spring 6 is connected between described disc 8 with described piston 4, described check spring 6 is sheathed in described sleeve 7, described sleeve 7 is sheathed in described piston 4, described sleeve 7 is by described packing ring, described lock washer and described bolt are fixedly installed on described disc, described bolt can use hex head setscrew, the described limited part 9 of described disc 8 on the inwall being located at described valve body 1, described limited part 9 in the form of a ring, one end of described suction port 10 on described valve body 1 and one end of described air outlet 11 all arrange screw thread, to connect different outer tube, thus be applicable to the air compressor of different size.
When described pressure controlled valve is applied to air compressor and starts, described suction port 10 place connects the compressed-air actuated outlet of air compressor, under the effect of described unlatching spring 3, when the compressed-air actuated pressure in air compressor is less than the default active force of described unlatching spring 3, cannot upwardly described disc 8 and described piston 4, now, the circulating pressure needed for lubricant oil preferentially set up by air compressor, guarantees the lubrication of air compressor;
When described compressed-air actuated pressure is greater than the default active force of described unlatching spring 3, under the effect of described compressed-air actuated pressure, promote described disc 8 and described piston 4, thus make pressurized air along with discharging described air outlet 11, now, air compressor can reduce the air velocity flowing through the thin shunt of oil, except guaranteeing the thin shunting effect of oil, the thin shunt of oil also can be protected to exempt from because pressure difference is too large and impaired;
After air compressor is shut down; during described compressed-air actuated pressure drop; described check spring 6 promotes described disc 8 immediately; prevent the gas backstreaming at described air outlet 11 place, after described disc 8 is pushed to described limited part 9, described piston 4 is also along with moving and returning to initial position; now; by described check spring 6, described piston 4 is cushioned, thus play cushioning effect in the collision process of described piston 4, promote the working life of described pressure controlled valve.
The pressure controlled valve provided in the present embodiment not only structure is simple, and guarantees could discharge when pressurized air in air compressor is more than certain force value.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
