Abstract
The utility model discloses a two stage inlet and outlet air exhaust reed valve for piston powered air compressors, comprising a valve board, inlet and outlet holes, inlet and outlet vale slices, inlet and outlet lift limiters and a spring slice. The limited two round hole space on the valve board are changed into a special large space by the reed valve. Thus, requirements of large exhaust volume air compressors can be satisfied. The spring slice is overlaid on the inlet valve slice, thus the anti-fatigue strength of the valve slice is improved, and the bending stress is reduced. The stress concentration points are dispersed, thus the service life of the valve slice is raised. The performance of the air compressor can be raised by the reed valve, and the service life is longer. The non-oil work can be realized. The reed valve is suitable for non-oil lubrication air compressors.
Description
The utility model relates to a kind of parts of pumping system, the air valve on specifically a kind of air compressor cylinder.
Air valve is one of critical component of piston type air compressor, its performance directly has influence on the reliability of air compressor and technology, economic performance index, used a kind of Reed Valve at present on mini air compressor, this Reed Valve is made up of valve plate, inlet hole, exhaust port and intake and exhaust valve block.Because the air displacement of mini air compressor is little, the suffered flexural stress of valve block is little, and the life-span is longer, in addition aisle spare do not need yet too big, so adopt Reed Valve can satisfy the performance requirement of mini air compressor.But for big cylinder diameter power air compressor, because its cylinder diameter is big, air displacement is big, and the valve plate aisle spare requires very big.If the employing Reed Valve, the one, port and valve block be difficult for to arrange, and main is that valve block is stressed is multiplied, and stress concentrates, and valve block is fractureed, and air valve is scrapped, and causes air compressor normally not use.Therefore, power be with can not adopting Reed Valve on the big cylinder diameter air compressor always for these years, but adopts ring valve.Ring valve is by the compression of valve spring and resilience, finishes the suction and discharge work of air valve.Because its moving element is many, friction point is many, noise is high, efficient is low, power consumption is big, reliability is relatively poor, and complex structure, and manufacture cost is higher.
The purpose of this utility model just provides a kind of power that is suitable for the Reed Valve that uses on the air compressor, to cut down the consumption of energy and noise, improves the reliability of air valve.
The utility model is achieved in that by valve plate 1, the valve block that is installed on the valve plate 1 constitutes the Reed Valve main body, on valve plate, have port, topped on the port have an intake and exhaust valve block, the intake and exhaust lift limiter of restriction lift of valve plate also is housed on valve plate, and superposition has spring sheet at the air-intake valve plate rear portion.
Because power is big with the air displacement of air compressor, on valve plate, be furnished with at least more than one inlet hole and at least more than one exhaust port, to increase Throughput, topped on each exhaust port have one group of exhaust valve plate and an exhaust lift limiter, to disperse power suffered on each exhaust valve plate, prolong the valve block life-span.Air-intake valve plate adopts the form by topped all inlet holes of valve block.Spring sheet at air-intake valve plate rear portion superposition, its shape and size are identical with the air-intake valve plate rear portion, and superposition has not only improved the fatigue resistance of valve block together greatly, and the flexural stress point that valve block fixed end root is concentrated is distributed to valve block middle part, the corresponding reduction of its stress numerical.Thereby make the life-span of air-intake valve plate improve greatly, and the power consumption that is lost on the valve block increases not quite, satisfied the needs of actual use.
The utility model changes limited two circular hole spaces on the valve plate into special-shaped large space, numerous air valves is arranged come, and has satisfied the requirement of the big circulation area of big discharge capacity air compressor.Add a spring sheet at the air-intake valve plate latter half part, increased the fatigue resistance of valve block, reduced flexural stress, disperseed stress concentration point, improved the working life of valve block.Replace original ring valve with this Reed Valve at 2V-3/8 type and 4V-6/8 type power on air compressor, can reduce by 0.2 kilowatt/meter of specific power
3/ minute, reach 5.85 kilowatts/meter
3/ minute; Noise reduces by 3 decibels, reaches 85.9 decibels (A); Air valve parts manufacture cost reduces by 20%.Reliable through form test in 500 hours and 48 hours spurt test proof air valve life-spans.The utility model is simple in structure, part is few, cost is low, good manufacturability, and performance of air compressor is improved, and ILS can realize not having oil work, is suitable for non-lubricated air compressor especially.
Below in conjunction with description of drawings embodiment.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to view.
Fig. 3 is the air-intake valve plate structural drawing.
Fig. 4 is chip architecture of the spring figure.
As shown in Figure 1, 2, on valve plate 1, have inlet hole 2 and exhaust port 3, topped on the inlet and outlet hole have air-intake valve plate 4 and an exhaust valve plate 5, and the air inlet lift limiter 6 and the exhaust lift limiter 7 of restriction lift of valve plate also is housed on valve plate 1, at air-intake valve plate 3 rear portion superpositions spring sheet 8 arranged.Inlet hole 2 is ellipse circumferential on valve plate 1 arranges, and has 12.The anterior ovalize (shown in Figure 3) of air-intake valve plate 4 covers whole inlet holes 4; The rear portion of air-intake valve plate 4 is T-shaped, is fixed in the bottom surface of valve plate 1; There is a slotted hole at the middle part of air-intake valve plate 4, and is relative with exhaust port, and other has a circular hole, is enclosed within on the air inlet lift limiter 6.Air inlet lift limiter 6 is the big nut bolt shape, is fixed in the bottom surface of valve plate 1, and nut and bottom surface have certain interval, makes the lift height of air-intake valve plate 4 be limited in the 2-3 millimeter.Exhaust port 3 on the valve plate 1 can have 4-7, among Fig. 1 is 5, topped one group of exhaust valve plate 5 and exhaust lift limiter 7 on each exhaust port.Exhaust lift limiter 7 is the lamellar that a bottom surface tilts, and is slightly longer than exhaust valve plate 5, is fixed on the valve plate 1 by screw 9, makes the lift height of outlet valve 5 be limited in the 3-4 millimeter.The bottom surface of exhaust lift limiter 7 preferably adopts involute shape inclined-plane.Exhaust valve plate 5 topped on each exhaust port is 2, can further improve the fatigue resistance of exhaust valve plate like this, increases the service life.Be " fourth " font with air-intake valve plate superposition spring sheet 8 together, with the rear shape of air-intake valve plate 4 and measure-alike, its top semicircular in shape, on a circular hole is arranged, be enclosed within on the air inlet lift limiter 6, the slotted hole at middle part is relative with exhaust port 5.The maximum ga(u)ge of spring sheet 8 is the 0.45-0.6 millimeter.The thickness of intake and exhaust valve block also selects the 0.45-0.6 millimeter to be advisable.The material of valve block and spring sheet can be selected spring steel for use, also can select reason allusion quotation valve block steel for use.For preventing that exhaust valve plate and exhaust lift limiter occurrence positions from moving, a locking plate can be installed, under the exhaust lift limiter with locking exhaust lift limiter and exhaust valve plate.
