Abstract
The utility model provides a liquid accuse switching -over device, including first hydraulically controlled check valve, the second hydraulically controlled check valve, first check valve, the second check valve, first check valve A mouth and first hydraulically controlled check valve A mouth are connected to guide's mouth of pilot operated directional control valve, second check valve A mouth and second hydraulically controlled check valve A mouth are connected to hydraulically controlled check valve guide mouth, guide's mouth of first hydraulically controlled check valve and the B mouth of first check valve intercommunication, guide's mouth of second hydraulically controlled check valve and the B mouth of second check valve intercommunication, the oil pipe way is let out in the B mouth connection of first hydraulically controlled check valve and second hydraulically controlled check valve. The utility model discloses in when switching -over, switching -over one end guide mouth passes through the check valve and connects pressure oil in guide's oil circuit, and the hydraulically controlled check valve connected of other end guide mouth is because its guide's mouth holds the oil circuit to be connected with the switching -over simultaneously, and the hydraulically controlled check valve is opened to make other end guide mouth and let out oil pipe way intercommunication, reach the purpose of quick pressure release, thereby make whole switching -over process more smooth.
Description
Technical field
The utility model relates to a kind of hydraulic pressure installation, particularly a kind of liquid controlled reversing device.
Background technique
Pilot operated directional control valve has now been widely used in Hydraulic Field, because it directly commutates by hydraulic control, therefore, it is possible to apply to a lot of special dimension, but arrange by guide's oil circuit completely due to it simultaneously, when pressure surge and pressure release obstacle appear in guide oil road, speed and the stability of its commutation cannot ensure.
Summary of the invention
For the deficiencies in the prior art, the utility model provides one that guide's oil circuit can be avoided to affect, and simultaneously self can the liquid controlled reversing device of pressure release in time.
The technical solution adopted in the utility model is: a kind of liquid controlled reversing device, comprise pilot operated directional control valve, Pilot operated check valve and one-way valve, described Pilot operated check valve comprises the first Pilot operated check valve and the second Pilot operated check valve, described one-way valve comprises the first one-way valve and the second one-way valve, the pilot port K1 of described pilot operated directional control valve connects the first one-way valve A mouth and the first Pilot operated check valve A mouth, described Pilot operated check valve pilot port K2 connects the second one-way valve A mouth and the second Pilot operated check valve A mouth, the pilot port Y1 of described first Pilot operated check valve is communicated with the B mouth of the first one-way valve, the pilot port Y2 of described second Pilot operated check valve is communicated with the B mouth of the second one-way valve, described first Pilot operated check valve is connected drain line X with the B mouth of the second Pilot operated check valve.
Utilize a high pressure turbocharger for described liquid controlled reversing device, comprise a bidirectional booster cylinder, the left and right piston cavity of described pressurized cylinder respectively arranges a hydraulic fluid port and a pilot port, and described two pilot port connect the B mouth of the first one-way valve and the second one-way valve respectively.
The utility model is when commutating, commutation one end pilot port connects pressure oil in guide's oil circuit by one-way valve, simultaneously the Pilot operated check valve that connects of the other end pilot port holds oil circuit to be connected with commutating due to its pilot port, Pilot operated check valve is opened, thus the other end pilot port is communicated with drain line X, reach the object of quick pressure releasing, thus make whole commutation process more smooth.The reverse cutoff function of one-way valve also can avoid selector valve pilot port to be subject to negative pressure impact in guide's oil circuit.
