Abstract
The utility model discloses an inlet and outlet combined air valve for an air compressor, which has the structure that the utility model is composed of inlet and outlet slices, inlet and outlet springs, an air inlet valve seat, an air outlet lift limiter, a valve board and screw bolts, wherein the valve board is provided with inlet and outlet channels; the air inlet valve seat and the air outlet lift limiter are tightly fixed on the valve board. After a cylinder cap is covered on the entire combined valve, an air inlet cavity and an air outlet cavity are formed. By adding the valve board, the utility model greatly simplifies the structure of the existing like product, and the manufacturing cost is reduced. Because the structure of the cylinder cap is adopted when the utility model is matched with an air cylinder, and thus, the radiation effect is also improved, and the performance of the air compressor is raised.
Description
The utility model belongs to a kind of valve, is specifically related to the intake and exhaust combination brake switch and proporting of a kind of use on the air compressor cylinder mouth.
Before the utility model is made, in the existing intake and exhaust combination brake switch and proporting partial installation of using on the air compressor cylinder mouth in the cylinder head inner chamber, its structure is made up of intake and exhaust valve block, air inlet and exhaust valve spring, intake and exhaust valve seat, air inlet lift limiter, exhaust lift limiter, intake and exhaust pressure cylinder, intake and exhaust gland, and the cylinder head inner chamber forms the inlet and outlet chamber.Its working procedure is divided into intake process and exhaust process, when the cylinder inner air pressure is lower than external air pressure, this pressure difference overcomes inlet valve spring power, open air-intake valve plate, so ambient air enters cylinder through cylinder head air-inlet cavity, inlet valve seat, air inlet lift limiter, finishes breathing process; When the cylinder inner air pressure is higher than external air pressure, this pressure official post air-intake valve plate is closed automatically, and overcomes exhaust valve spring power, opens exhaust valve plate, air is discharged through delivery valve seat, exhaust lift limiter, cylinder head exhaust cavity in the cylinder, finishes exhaust process.But the defective that existing intake and exhaust combination brake switch and proporting exists is complex structure, manufacture cost height.
The purpose of this utility model provides a kind of air compressor intake and exhaust combination brake switch and proporting of new structure, and this valve has the identical performance of existing intake and exhaust combination brake switch and proporting, but simple in structure, low cost of manufacture.
The purpose of this utility model is finished by following technical proposals:
The utility model is a kind of air compressor intake and exhaust combination brake switch and proporting, its structure comprises air-intake valve plate, exhaust valve plate, inlet valve spring, exhaust valve spring, inlet valve seat, exhaust lift limiter, its structure outline is: a valve plate has been set up in the combination brake switch and proporting bottom, have the inlet and outlet passage on the valve plate, inlet valve seat, exhaust lift limiter are fastened on the valve plate; Whole combination brake switch and proporting covers the back by cylinder cap and forms air-inlet cavity, exhaust cavity.
The utility model in the specific implementation, the inlet and outlet channel shape on the valve plate is in the form of a ring.
Compare with the air compressor intake and exhaust combination brake switch and proporting of prior art, because the utility model improves traditional air compressor intake and exhaust combination brake switch and proporting, by increasing a valve plate, on this valve plate except that being provided with ring-type inlet and outlet passage, the effect of air inlet lift limiter and delivery valve seat of on function, also having held concurrently, save air inlet lift limiter, delivery valve seat, intake and exhaust pressure cylinder, intake and exhaust gland, therefore simplified original structure greatly, reduced manufacture cost; Moreover by architecture advances, combination brake switch and proporting of the present utility model no longer relies on cylinder head structure and cylinder to go coupling, and can change the cylinder cap structure that is suitable for die casting into, has therefore improved radiating effect, has improved performance of air compressor.
The utility model is further described in detail by embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment sectional structure schematic representation;
Fig. 2 sheds plan structure schematic representation behind the cylinder cap for Fig. 1;
Referring to Fig. 1, Fig. 2.The utility model example structure is by valve plate 1, air-intake valve plate 9, exhaust valve plate 2, inlet valve spring 7, exhaust valve spring 5, inlet valve seat 6, exhaust lift limiter 3, and bolt 4, bolt 8, cylinder cap 10, bolt 11 are formed, and valve plate 1 is a single piece.Wherein air-intake valve plate 9, inlet valve spring 7, inlet valve seat 6, valve plate 1, bolt 8 etc. are formed the suction valve assembly; Exhaust valve plate 2, exhaust valve spring 5, exhaust lift limiter 3, valve plate 1, bolt 4 etc. are formed exhaust valve component; Suction valve assembly and exhaust valve component cover in the cylinder cap 10 by bolt 11, form air-inlet cavity A, exhaust cavity B.
Brief description the utility model embodiment's working procedure:
Its working procedure also is divided into intake process and exhaust process, when the cylinder inner air pressure is lower than external air pressure, this pressure difference overcomes inlet valve spring 7 power, open air-intake valve plate 9, so ambient air enters cylinder through cylinder cap passage a, cylinder cap air-inlet cavity A, inlet valve seat passage b, valve plate gas-entered passageway c, finishes breathing process; When the cylinder inner air pressure is higher than external air pressure, this pressure official post air-intake valve plate 9 is closed automatically, and overcomes exhaust valve spring 5 power, opens exhaust valve plate 2, air is discharged through valve plate exhaust passage d, cylinder cap exhaust cavity B, cylinder cap passage e in the cylinder, finishes exhaust process.
