Abstract

The utility model provides a fast differential circuit which comprises a hydraulic cylinder, a piston rod, a solenoid directional valve and a solenoid valve. The piston rod is arranged in the hydraulic cylinder and moves in a reciprocating mode. The solenoid directional valve is communicated with a left cavity of the hydraulic cylinder, and the solenoid valve is communicated with the solenoid directional valve. The solenoid valve is communicated with a right cavity of the hydraulic cylinder, and further communicated with the left cavity of the hydraulic cylinder. The fast differential valve is not only simple in structure and low in cost, but also fast in working, reliable and small in energy consumption.

Description

Quick differential circuit
Technical field
The utility model is specifically related to quick differential circuit.
Background technique
Differential circuit is from the rodless cavity oil-feed, make the oil of rod chamber get back to rodless cavity, under same pressure, utilize the area difference of rodless cavity and rod chamber, it is poor to produce pressure F, stretches out thereby drive oil hydraulic cylinder, because the oil of rod chamber has been got back to rodless cavity, so oil hydraulic cylinder can move with fast speed, realize that small flow is high-speed, existing differential circuit complex structure, cost height, power consumption are greatly.
Summary of the invention
Technical problem to be solved in the utility model is to provide quick differential circuit, and not only simple structure, cost are low, and work fast, reliable, power consumption is little.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: quick differential circuit, comprise oil hydraulic cylinder, be located at the piston rod that moves reciprocatingly in the oil hydraulic cylinder, the solenoid directional control valve that is communicated with the left chamber of oil hydraulic cylinder, the solenoid valve that is communicated with solenoid directional control valve, described solenoid valve is communicated with the right chamber of oil hydraulic cylinder, and described solenoid valve also is communicated with the left chamber of oil hydraulic cylinder.
As preferably, also be provided with one-way valve and the Flow valve that is connected in parallel on the one-way valve between described solenoid directional control valve and the solenoid valve, when this structure moved right when piston rod, in-line flow into the left chamber of oil hydraulic cylinder by solenoid directional control valve, passed through at last the solenoid directional control valve oil return by solenoid valve to Flow valve, when piston rod is moved to the left, solenoid directional control valve and solenoid valve commutation, in-line enters the right chamber of oil hydraulic cylinder by one-way valve to solenoid valve, from oil hydraulic cylinder left chamber oil return, working stability connects fast.
As preferably, described solenoid directional control valve adopts three position four-way electromagnetic valve, and this structure solenoid directional control valve adopts three position four-way electromagnetic valve, when whole system is not worked, solenoid directional control valve is in meta, when piston rod moved right, solenoid directional control valve was in left position, and hydraulic oil enters the left chamber of oil hydraulic cylinder through solenoid directional control valve, when piston rod is moved to the left, solenoid directional control valve is in right position, and hydraulic oil enters the right chamber of oil hydraulic cylinder through solenoid directional control valve and one-way valve, and is easy to operate.
As preferably, described solenoid valve adopts two-position two-way solenoid valve, and this structure solenoid valve adopts two-position two-way solenoid valve, and is rational in infrastructure, easy to operate.
Beneficial effect:
The utility model adopts technique scheme that quick differential circuit is provided, and not only simple structure, cost are low, and work fast, reliable, power consumption is little.
