Embodiment
Below by drawings and Examples, technical solutions of the utility model are described in further detail.
As Fig. 1 and Fig. 2 respectively illustrates exploded view and the plan view of a specific embodiment of the utility model integrated valve, the first on-off valve V1, the second on-off valve V2 that this integrated valve comprises valve block 1 and is arranged on described valve block 1, described valve block has load ports R, unloading port S and oil-feed port P; As figure, the first on-off valve V1 and the second on-off valve V2 is integrated on valve block 1, thus is convenient to safeguard and change.The first on-off valve in the present embodiment and the second on-off valve also can be chosen as electromagnetism one-way valve, as long as meet required function.
Fig. 3 a, 3b, 4a and 4b illustrate the sectional view in Fig. 2 in A-A, B-B, C-C, D-D respectively.As shown in Fig. 3 a, 3b, 4a and 4b, in valve block 1, oil-feed port P is communicated with the entrance I1 of described first on-off valve V1, described load ports R is communicated with the outlet O1 of described first on-off valve V1, the outlet O1 of described first on-off valve V1 is also communicated with the entrance I2 of the second on-off valve V2, and described unloading port S is communicated with the outlet O2 of the second on-off valve V2; Like this, all connecting pipelines are all positioned at the inside of this valve block 1, because this reducing outside pipeline, improve integration, thus being convenient to installation and maintenance.In order to the loading end oil mass realizing integrated valve is adjustable, a throttling arrangement 2 is set in the passage P1 that the entrance I1 of the first on-off valve V1 is communicated with oil-feed port P.Like this, when loading hydraulic oil to the LOADED CAVITY of such as compressor oil cylinder, controlling oil mass by this throttling arrangement 2, thus the Slow loading of hydraulic oil in the LOADED CAVITY of compressor oil cylinder can be realized, thus meeting the demand of compressor energy adjustment.
In the present embodiment, it is inner that throttling arrangement 2 is connected to described passage P1 in removable mode.Like this, according to the needs of working conditions of compressor, the throttling arrangement 2 of replaceable different model, to meet compressor energy adjustment demand.
In another embodiment, throttling arrangement 2 is adjustable throttling arrangement, is regulated the flow of this throttling arrangement 2 by mode that is artificial or that automatically regulate, like this, according to the needs of working conditions of compressor, the flow of adjustable throttle device 2, to meet compressor energy adjustment demand.
For the ease of detecting charge oil pressure, to judge piston mode, be convenient to maintenance conditions, the valve block 1 in the present embodiment also has pressure tap 3, described pressure tap 3 is provided with load cell 4, and pressure tap 3 is all communicated with the entrance I2 of the second on-off valve V2 with the outlet O1 of the first on-off valve V1.Load cell 4 can be the conventional load cells such as such as needle-valve.
Referring again to Fig. 1, first on-off valve V1 and the second on-off valve V2 includes housing, is positioned at the coil 5 of housing and is positioned at the spool 6 of coil 5, one end of described spool 6 is fixed with mounting flange 7, and spool 6 is alternatively connected on described valve block 1 through mounting flange 7.Like this, when on-off valve breaks down, can change easily, and need not rearrange oil circuit again, therefore installation and maintenance is got up more for convenience.
In the present embodiment, rubber pad 11 is also set between mounting flange 7 and valve block 1, this rubber pad 11 arranges through hole, so that the internal oil passages of the outlet of on-off valve and entrance and this valve block 1 is connected.In the present embodiment, by fixing device, such as pair of bolts 10, is fixed to on-off valve on this valve block 1.
For the ease of load ports R, unloading port S, oil-feed port are communicated to outside oil circuit, in the present embodiment, on described load ports R, unloading port S and oil-feed port P, pipe joint 8 is all installed, for being connected to outside oil circuit.In order to prevent wearing and tearing, at pipe joint, 8 times pad 9 can also be set.
Fig. 5 shows the fundamental diagram of a kind of compressor of the specific embodiment comprising integrated valve of the present utility model.As shown in Figure 5, this compressor comprises the oil cylinder having and have bar piston PL, and this has bar piston PL that this oil cylinder is divided into rodless cavity C2 and rod chamber C1, is provided with Returnning spring S1 so that piston reset in described rodless cavity C2.The loading R of above-mentioned integrated valve is communicated to rod chamber C1, and unloading port S is communicated with rodless cavity C2.Can also be clear that from this schematic diagram, in the passage between the entrance that throttle element 3 is arranged on oil-feed port P and the first on-off valve V1.Described compressor can also comprise guiding valve V3, and this compressor can be opened compressor, and described rod chamber C1 is stretched out in the one end of bar piston that has of this opened compressor, and is connected with described guiding valve V3.
In addition, in order to realize oil return, rodless cavity C2 is communicated with a low-pressure cavity, such as compressor low-pressure cavity, enters in the oil content of band oil storage function finally by compressor effect by relief opening, realizes oil circulation.
Below in conjunction with structure of the present utility model, working principle of the present utility model is simply described: 1) when compressor loads, first on-off valve V1 obtains the signal opened, hydraulic oil passes through the first on-off valve V1 from oil-feed port P after throttle element 2 throttling, now the second on-off valve V2 closes, therefore hydraulic oil arrives rod chamber C1 and the LOADED CAVITY of oil cylinder by load ports R, piston PL promotes guiding valve V3 and moves, due to the effect of throttle valve 2, the action of Slow loading can be realized during loading, thus be beneficial to the energy adjustment of compressor.And the hydraulic oil that namely rodless cavity C2 unloads in chamber flows back to low-pressure cavity L.Wherein throttle element 2 is replaceable or adjustable, for regulating compressor loads speed; 2) when a compressor is unloaded, first on-off valve V1 closes, and the second on-off valve V2 opens, and oil cylinder piston is return rapidly under spring S1 thrust, hydraulic oil in rod chamber C1 is back in rodless cavity C2 through the second on-off valve V2 by unloading port R, thus reaches unloading object.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to embodiment of the present utility model or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope of the utility model request protection.
