Problems solved by technology
At present, the reversing method of the hydraulic control booster valve mostly adopts an external control reversing valve for reversing to achieve the purpose of boosting. The disadvantage is that the degree of automation is low, and automatic reversing boosting cannot be realized.
There is also a supercharging valve that can realize automatic reversing supercharging, but it belongs to one-way supercharging, that is, when the supercharging piston moves to the left (or right), it acts as a supercharging effect, and when the supercharging piston moves to the right (or left) (Reset) does not work as a pressurizer, so the working efficiency is low

The invention discloses a double-acting automatic pressure increasing valve. The valve comprises a piston shell and a cross piston, wherein a cavity A and a cavity D are formed between the left and right end piston faces of a horizontal piston body of the cross piston and the piston shell respectively; a cavity B and a cavity C are formed between the left and right piston faces of a vertical piston body of the cross piston and the piston shell respectively; the cavity A and the cavity D are communicated with a high-pressure liquid outlet through a left liquid outlet one-way valve and a right liquid outlet one-way valve, and are communicated with the cavity B, the cavity C and two work valve ports of a two-position four-way liquid control reversing valve through a left liquid inlet one-wayvalve and a right liquid inlet one-way valve; the liquid inlet of the two-position four-way liquid control reversing valve is communicated with the liquid outlet of a left carrier rod one-way valve; a left-position liquid control port is communicated with the liquid outlet of the left carrier rod one-way valve; a carrier rod of the left carrier rod one-way valve extends to the cavity A; a right-position liquid control port is communicated with the liquid inlet of the left carrier rod one-way valve and the liquid outlet of a right carrier rod one-way valve; a carrier rod of the right carrier rod one-way valve extends to the cavity D; and the liquid inlet of the right carrier rod one-way valve is communicated with a liquid return port. The valve fulfills the aim of bidirectional automatic pressure increasing.
Description
technical field [0001] The invention relates to a hydraulically controlled booster valve, in particular to a double-acting automatic booster valve. Background technique [0002] A booster valve is a booster valve that converts low-pressure oil in a hydraulic transmission system into high-pressure oil in proportion. It is composed of a valve body, a supercharger and a hydraulic reversing valve. Through the cooperation of the inlet and outlet oil passages in the valve body, the control oil hole and the oil discharge valve, the supercharger and the hydraulic reversing valve are organically combined. At present, the reversing method of the hydraulic control booster valve mostly adopts an external control reversing valve for reversing to achieve the purpose of boosting. The disadvantage is that the degree of automation is low, and automatic reversing boosting cannot be realized. There is also a supercharging valve that can realize automatic reversing supercharging, but it belon...
