Abstract
The utility model provides a high and low pressure conversion device. The high and low pressure conversion device comprises a first oil cylinder A, a second oil cylinder B, an electromagnetic reversing valve and a connecting plate, wherein the first oil cylinder A comprises a rodless cavity A1 and a rod cavity A2; the second oil cylinder B comprises a rodless cavity B1 and a rod cavity B2; the electromagnetic reversing valve is a two-position six-way valve; and four ports of the electromagnetic reversing valve are respectively communicated with the rodless cavity A1 and the rod cavity A2 of the first oil cylinder A and the rodless cavity B1 and the rod cavity B2 of the second oil cylinder B through four oil circuit through holes of the connecting plate. The original valve body and valve cover are replaced by the electromagnetic reversing valve, so that the high and low pressure conversion device can finish high and low pressure conversion only through one electric control button. Compared with the prior art, the high and low pressure conversion device has the advantages that the device is easy to operate and is environment-friendly and safe; and a machine is not required to be dismounted, so that time is saved.
Description
[technical field]
The utility model relates to a kind of hydraulic pressure installation, is specifically related to the conversion equipment of high low pressure state exchange in the hydraulic pressure installation.
[background technique]
The hydraulic pressure high low pressure conversion equipment that uses now is made up of two oil cylinders, two conversion equipments (dividing valve body and valve gap two-part), a connecting plate.Two conversion equipments are installed in two oil cylinder afterbodys respectively and connect with connecting plate.Wherein the valve body of conversion equipment and valve gap are to link together with bolt.If desired high low pressure when conversion, must all connecting bolts be pulled down, again valve gap rotated 90 degree, the pairing again through pairing in valve body and the valve gap and oil duct realizes high low pressure conversion.
Therefore, there is following shortcoming in existing high low pressure conversion equipment: 1, want demounting bolt and manual switch, troublesome poeration; 2, also a large amount of leakages cause waste and environmental pollution to hydraulic oil owing to dismantle; If 3 do not have pressure release also can cause injury to personnel.
[model utility content]
The technical problem that the utility model need solve provides a kind of easy to operate, does not need the teardown of engine and high low pressure conversion equipment that oil duct is matched again
According to the above-mentioned technical problem that needs solution; Designed a kind of high low pressure conversion equipment; Comprise the first oil cylinder A, the second oil cylinder B, solenoid directional control valve and connecting plate, the first oil cylinder A comprises rodless cavity A1 and rod chamber A2, and the second oil cylinder B comprises rodless cavity B1 and rod chamber B2; Said solenoid directional control valve is two six-way valves, and its four interfaces are communicated with the rodless cavity A1 of the first oil cylinder A and rodless cavity B1 and the rod chamber B2 of the rod chamber A2 and the second oil cylinder B through four oil circuit through holes of connecting plate respectively.
Further improve as the utility model, said solenoid directional control valve also is provided with automatically controlled button.
The utility model high low pressure conversion equipment has adopted solenoid directional control valve to replace original valve body and valve gap, only needs an automatically controlled button just can accomplish the high low pressure conversion.Compared with prior art, the utility model is simple to operate, Environmental Safety more, thereby must not save time by the teardown of engine.

[embodiment]
Below in conjunction with accompanying drawing and mode of execution the utility model is described further.
As depicted in figs. 1 and 2, be a kind of embodiment of the utility model high low pressure conversion equipment, this high low pressure conversion equipment comprises two oil cylinder A, B arranged side by side, solenoid directional control valve 1 and connecting plate 2.Two oil cylinders arranged side by side are categorized as the first oil cylinder A and the second oil cylinder B, and wherein, like Fig. 3 and shown in Figure 4, the first oil cylinder A comprises rodless cavity A1 and rod chamber A2, and the second oil cylinder B comprises rodless cavity B1 and rod chamber B2.Said solenoid directional control valve 1 is installed on the connecting plate 2, and this connecting plate 2 is provided with four oil circuit through holes.This solenoid directional control valve 1 is two six-way valves; Its four interfaces are corresponding with four oil circuit through holes of connecting plate respectively, and are communicated with the rodless cavity A1 of the first oil cylinder A and rodless cavity B1 and the rod chamber B2 of the rod chamber A2 and the second oil cylinder B respectively through four oil circuit through holes on the connecting plate.
Said solenoid directional control valve also is provided with automatically controlled button 3, and under the normal condition, the solenoid directional control valve no electric circuit is when pressing automatically controlled button 3, the solenoid directional control valve energising.
As shown in Figure 3, be the oil circuit circulation figure of the utility model high low pressure conversion equipment low-pressure state, at this moment, and the solenoid directional control valve no electric circuit, from the low pressure position, whole oil-way system is in low-pressure state, and pressure oil gets into A2 and B2 from the P mouth, and work is in low-pressure state.
Otherwise, as shown in Figure 4, be the oil circuit circulation figure of the utility model high low pressure conversion equipment high pressure conditions, at this moment, and the solenoid directional control valve energising, from the high pressure position, whole oil-way system is in high pressure conditions, and pressure oil gets into A1 and B1 from the P mouth, and work is in high pressure conditions.
The utility model high low pressure conversion equipment has adopted solenoid directional control valve to replace original valve body and valve gap, only needs an automatically controlled button just can accomplish the high low pressure conversion.Compared with prior art, the utility model is simple to operate, Environmental Safety more, thereby must not save time by the teardown of engine.
Above-described only is the mode of execution of the utility model; Should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; Can also make improvement, but these all belong to the protection domain of the utility model.
