Abstract
The utility model discloses an under-pressure starting device of a compressor. The under-pressure starting device comprises a valve plate, an exhaust valve sheet and an air inlet valve sheet, wherein the valve plate is provided with an air inlet hole and an air exhaust hole; and the exhaust valve sheet and the air inlet valve sheet are respectively fastened on the valve plate via screws. The under-pressure starting device of the compressor is characterized in that the valve plate is equipped with an inclined plane groove; the air inlet hole is placed on the bottom of the inclined plane groove; the air inlet valve sheet is mounted on the inclined plane groove; and a certain pressure-relief gap is arranged between the air inlet valve sheet and an inclined plane of the inclined plane groove. The under-pressure starting device of the compressor is simply structured with simple installation; under-pressure starting of the compressor can be achieved, thereby possessing great promotion value.
Description
Technical field
The utility model relates to Compressor Technology field, relates to more specifically a kind of band pressure startup device of compressor.
Background technique
At present, at present, the valve plate of the compressor occurring on market is the bottom that is fixed on air valve, on valve plate, be provided with valve block, valve block is all slabbing, valve plate and valve block are with screw fastening, and locking method is all locked with screw or compressor cylinder cover compresses, and it is for the sealing of compressor inlet and outlet.But in the time of compressor or vacuum machine startup, generally all can not with pressurely start, many artificers seek method from many approach, but are all unsuccessful.
Summary of the invention
The purpose of this utility model is exactly the deficiency in order to solve prior art and the one compressor band pressure startup device simple in structure, easy to use that provides.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of compressor band pressure startup device, comprise valve plate, exhaust valve plate, air-intake valve plate, valve plate is provided with inlet hole and exhaust port, exhaust valve plate and air-intake valve plate are fixed by screws in respectively on valve plate, it is characterized in that, described valve plate is provided with inclined plane groove, and inlet hole is arranged on the bottom of inclined plane groove, and air-intake valve plate is arranged on inclined plane groove.
As further illustrating of such scheme, the top of described outlet valve is provided with limiting stopper, and screw is successively through limiting stopper and exhaust valve plate.
One end of described limiting stopper is fixed by screws on valve plate, and the other end is upturned, and bending angle is not more than 20 degree.
There is certain release gap on the inclined-plane of described air-intake valve plate and inclined plane groove.
The below of described air-intake valve plate is provided with valve spacer, and screw is successively through valve spacer and air-intake valve plate.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the inclined-plane of air-intake valve plate and inclined plane groove to have certain gap, in the time of compressor start, lays down partial pressure, and compressor operation is started, and promotes the exhaust valve plate with pressure after compressor start again, reaches and is with pressure-activated object.

Fig. 2 is polycrystalline substance schematic diagram of the present utility model.
Description of reference numerals: 1, valve plate 2, exhaust valve plate 3, air-intake valve plate 4, inlet hole 5, exhaust port 6, screw 7, screw 8, inclined plane groove 9, limiting stopper 10, valve spacer.
Embodiment
As depicted in figs. 1 and 2, a kind of compressor band of the utility model pressure startup device, comprise valve plate 1, exhaust valve plate 2, air-intake valve plate 3, valve plate 1 is provided with inlet hole 4 and exhaust port 5, exhaust valve plate 2 and air-intake valve plate 3 are fixed on valve plate 1 by screw 6,7 respectively, and valve plate 1 is provided with inclined plane groove 8, and inlet hole 4 is arranged on the bottom of inclined plane groove 8, air-intake valve plate 2 is arranged on inclined plane groove 8, and air-intake valve plate 2 has certain release gap with the inclined-plane of inclined plane groove 8.The top of exhaust valve plate 2 is provided with limiting stopper 9, and screw 6 is successively through limiting stopper and exhaust valve plate.The below of air-intake valve plate 3 is provided with valve spacer 10, and screw 7 is successively through valve spacer and air-intake valve plate.In the present embodiment, one end of limiting stopper 9 is fixed by screws on valve plate, and the other end is upturned, and bending angle is 15 degree.
In compressor start process, because there is certain gap on the inclined-plane of air-intake valve plate and inclined plane groove, in the time of compressor start, lay down partial pressure, compressor operation is started, after compressor start, promote again the exhaust valve plate with pressure.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
