Hand -operated direction valve and magenetic exchange valve pass through bolt interconnect, the inside oil duct of hand -operated direction valve and magenetic exchange valve be connected, magenetic exchange valve's the main oil inlet of work oil inlet and hand -operated direction valve relative and establish, magenetic exchange valve's the main oil return opening of work oil return opening and hand -operated direction valve relative and establish. The utility model discloses convenient operation, simple structure, size are little, very convenient installing on various engineering machinery and agricultural machine, and the disconnect -type valve body makes the maintenance more convenient, and has an operating performance of switching -over valve that floats in the existing market and compares the utility model discloses improve a lot, have very high in -service use and worth.
Description
Technical field
The utility model belongs to the common selector valve of hydraulic system in engineering machinery and farm machinery, the switchable selector valve of a kind of Median Function specifically.
Background technique
The existing hand-operated direction valve with floating bit is mostly four six-way transfer valves, its complex structure, and volume is comparatively large, causes operation inconvenience because its position is more.
Summary of the invention
The utility model provides the switchable selector valve of a kind of Median Function, and it can make the Median Function of selector valve switch between M type and H type, in case operator misses pulling process bar and causes cylinder efficient unstable.
The utility model realizes above-mentioned purpose by the following technical solutions:
The switchable selector valve of a kind of Median Function, it comprises a hand-operated direction valve and a solenoid directional control valve composition.
Described hand-operated direction valve and solenoid directional control valve are inter-connected via a bolt joint, described hand-operated direction valve is connected with the oil duct of solenoid directional control valve inside, the work filler opening of described solenoid directional control valve is relative with the main filler opening of hand-operated direction valve and establish, and the work return opening of described solenoid directional control valve is relative with the main return opening of hand-operated direction valve and establish.
Described hand-operated direction valve is 3-position 4-way hand-operated direction valve, and described solenoid directional control valve is two position, three-way electromagnetic change valve.
The utility model adopts technique scheme to have following beneficial effect:
This model utility is easy to operate, structure is simple, size is little, can be arranged on very easily on various engineering machinery and farm machinery, separated type valve body makes maintenance convenient, with in the market with floating bit selector valve operating characteristics compared with the utility model improve a lot, there is very high actual use value.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram installing hydraulic system of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.
The switchable selector valve of a kind of Median Function as shown in Figure 1, it comprises a hand-operated direction valve 1 and a solenoid directional control valve 2 forms; Described hand-operated direction valve 1 is 3-position 4-way hand-operated direction valve, and described solenoid directional control valve 2 is two position, three-way electromagnetic change valve.
Described hand-operated direction valve 1 and solenoid directional control valve 2 are inter-connected via a bolt joint, described hand-operated direction valve 1 is connected with the oil duct of solenoid directional control valve 2 inside, the work filler opening 21 of described solenoid directional control valve 2 is relative with the main filler opening 11 of hand-operated direction valve 1 and establish, and the work return opening 22 of described solenoid directional control valve 2 is relative with the main return opening 12 of hand-operated direction valve 1 and establish.
As shown in Figure 2 for being provided with hydraulic system of the present utility model, it, at hydraulic oil container outer connecting fluid press pump 3, selector valve of the present utility model and oil cylinder 4 successively, has relief valve 5 at the parallel connection outside of oil hydraulic pump.
In the process of equipment work, hand when push away or pulling process handle time oil cylinder bar can realize rising or declining, when decontroling operating grip, cylinder bar stops rising or decline and oil cylinder oil inlet and outlet are shut.Now press solenoid operated button, it is that Median Function becomes from original M type the floating connection that H type achieves oil cylinder that the work filler opening 21 on selector valve, work return opening 22, main filler opening 11, main return opening 12 are interconnected.First press electromagnetic valve switch when now if oil cylinder bar needs rising or declines to make solenoid valve power-off, and then push-and-pull operating handle.Before not pressing electromagnetic valve switch, push-and-pull operating handle selector valve is still in H type Median Function in any case, and such oil cylinder in case operator misses pulling process bar and causes cylinder efficient unstable, has H type Median Function lock function when being in quick condition.
