Abstract

The invention belongs to the technical field of hydraulic control and specifically relates to an energy accumulator liquid filling integrated valve. The energy accumulator liquid filling integrated valve comprises a flow priority valve, a liquid filling valve and an electromagnetic switching valve set. The flow priority valve comprises a three-position four-way valve and a damping II. An oil inletof the three-position four-way valve is connected with an oil port P. The liquid filling valve comprises a one-way valve, a two-position two-way valve I, an overflow valve and an adjustable throttling valve II. An oil port A of the three-position four-way valve communicates with an oil inlet of the one-way valve. An oil outlet of the one-way valve is connected with an oil port P3. The oil port Pis connected with an oil inlet of the two-position two-way valve I through the damping II. An oil outlet of the two-position two-way valve I is connected with an oil port T1. A spring cavity of the three-position four-way valve is connected with an oil inlet of the two-position two-way valve I. The overflow valve and the adjustable throttling valve II are connected between the oil port T1 and theoil port P3 in parallel. An oil port B of the three-position four-way valve is connected with an oil port P1. Through the integrated flow priority valve of the energy accumulator liquid filling integrated valve, switching and synchronous operating of an energy accumulator and a tamping device main valve can be realized.

Description

technical field [0001] The invention belongs to the technical field of hydraulic control, and in particular relates to an accumulator fluid-charging integrated valve. Background technique [0002] The railway tamping device is often used for tamping and maintenance of the roadbed on both sides of the railway. During the construction process, it is required to be able to perform continuous and rapid operations. In order to meet its high-efficiency work needs, it is necessary to increase the speed of the lowering action of the tamping device. Currently, the commonly used speed-up solutions such as the use of large-displacement pumps and confluence valves cannot meet the speed requirements. It is necessary to add an accumulator and its filling valve in the tamping device. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides an accumulator fluid-filling integrated valve, through which the int...
