In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to further explain the present invention in detail. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

In the application, the pressure cylinder 1, the one-way valve 13, the oil supplementing manual ball valve 17 and the pressure relief electromagnetic directional valve 14 are directly mounted and used in a matching mode after being purchased from the market according to specific models.

In the present application, a pressure cylinder 1 with a strict pressure increase ratio is provided in the circuit, and according to the principle of force balance, the primary pressure P1 multiplied by the area A1 of the first cavity 4 of the pressure cylinder 1 is equal to the secondary pressure P2 multiplied by the area A2 of the second cavity 5 of the pressure cylinder, i.e. P1 × A1= P2 × A2, for example, when the area ratio of the first cavity 4 and the second cavity 5 of the pressure cylinder 1 is 3, i.e. A1/A2=3/1, the ratio of the primary pressure to the secondary pressure is 1, i.e. P1/P2=1/3, i.e. the secondary pressure is 3 times the primary pressure. So as to achieve the purpose of strict pressurization.

The pressure increasing ratio in the application can be adjusted at will, and the use requirements of various different occasions are met.

As shown in fig. 1, the novel booster cylinder type booster circuit comprises a booster cylinder 1, wherein a piston rod 2 is movably arranged in the booster cylinder 1, a piston 3 is fixed at the end part of the piston rod 2, and the piston 3 divides an inner cavity of the booster cylinder 1 into a first cavity 4 and a second cavity 5; the lower part of the first cavity 4 is communicated with a primary pressure input pipeline 6; the upper end of the second cavity 5 is communicated with a secondary side pressure input pipeline 7; one side of the second cavity 5 is also communicated with a low-pressure oil supplementing pipeline 8; the other side of the second cavity 5 is communicated with an oil drainage pipeline 9, and the end part of the oil drainage pipeline 9 is communicated with an oil drainage tank 10.

Wherein, the primary side pressure input pipeline 6 is also provided with a side pressure measuring port 11. A secondary pressure measuring port 12 is arranged on the secondary pressure input pipeline 7. The low-pressure oil supplementing pipeline 8 is also provided with a check valve 13. The oil discharge pipeline 9 is also provided with a pressure discharge electromagnetic directional valve 14. One side of the pressure cylinder 1 is also communicated with a high-level oil supplementing pipeline 15, and the end part of the high-level oil supplementing pipeline 15 is connected with a high-level oil supplementing oil tank 16. And the high-level oil supplementing pipeline 15 is also provided with an oil supplementing manual ball valve 17.

The working principle of the novel booster cylinder type boosting loop is as follows:

firstly, oil is fed from a primary side pressure input pipeline 5, and after being pressurized by a pressurizing cylinder 1, pressurized pressure is output from a secondary side pressure input pipeline 7. When the pressure of the loop is increased and needs to be reduced, the pressure reduction electromagnetic directional valve 13 acts for reversing, and the pressure of the high-pressure cavity of the pressure cylinder 1 is reduced to the oil drainage oil tank 10. After the pressurization of the pressurization cylinder 1 is completed for one time or before the pressurization is restarted, the piston 3 of the pressurization cylinder 1 is pushed to the bottommost part of the first cavity 4 at one side of the pressurization cylinder 1 through the one-way valve 13 by the low-pressure oil supplementing pipeline 8 so as to ensure the continuity of the pressurization. In the working process of the whole pressurizing loop, the excessive or needed oil liquid generated by the volume change of the middle cavity of the pressurizing cylinder 1 is stored and supplemented by a high-level oil supplementing oil tank 16 through an oil supplementing manual ball valve 17.

The traditional pressurization loop adopts the mode that the whole hydraulic loop is designed into an ultrahigh pressure pump from a power source pump, a pressure control valve is an ultrahigh pressure control valve, namely the whole hydraulic system is subjected to ultrahigh pressure control, and each part has a pressurization risk in the pressurization process; the overall pressurization cost is also high.
