Embodiment Construction

[0011] The present invention will be further described below with reference to the accompanying drawings and in conjunction with the embodiments.

[0012] A two-way hydraulically controlled one-way valve according to the present invention includes a valve body, two one-way valves corresponding to each other, a left control piston and a right control piston arranged between the two one-way valves, and the left and right control pistons are arranged in the valve body. 1. A control valve core is arranged between the right control piston, and an oil inlet passage is arranged on the valve body, and the oil inlet passage respectively passes through respective one-way valves.

[0013] Refer to attached figure 2 The oil inlet is divided into V1 and V2. V1 leads to C1, and V2 leads to C2. The valve body is also equipped with an X control port connected to the valve core. If oil enters V1, the oil enters through the check valve. Port C1. At the same time, the high-pressure oil at por...

Abstract

The invention provides a two-way hydraulic control one-way valve. The two-way hydraulic control one-way valve comprises a valve body, two one-way valves, a left control piston and a right control piston, wherein the two corresponding one-way valves are arranged in the valve body, the left control piston and the right control piston are arranged between the two one-way valves; a control valve element is arranged between the left control piston and the right control piston, an oil inlet channel is formed in the valve body, the oil inlet channel can be controlled internally and externally throughthe two-way hydraulic control one-way valve of a novel one-way valve structure, the opening of the one-way valve can be controlled through an oil way in the pipeline, and the one-way valve can be controlled to be opened through an external oil way, so that the operation of a hydraulic system is simplified, and therefore the operation of the hydraulic system is simplified.

Description

technical field [0001] The invention relates to a hydraulic control one-way valve, in particular to a two-way hydraulic lock. Background technique [0002] Check valves are mostly used in existing hydraulic systems (especially engineering machinery such as hydraulic drilling rigs and hydraulic drilling rigs), which are control valves that only allow oil to flow in one direction. The hydraulic control check valve is a valve that relies on the pressure of the control fluid to reverse the flow of the check valve. [0003] Two hydraulically controlled one-way valves are symmetrically arranged, and a control piston is used to form a commonly used two-way hydraulic lock. The control oil circuit is internally controlled (such as figure 1 ). Ports V1 and V2 are connected to reversing valves, ports C1 and C2 are connected to actuators. It can control the on or off of the oil in the two pipelines. Its working principle is that one way of oil can pass through the one-way valve dire...
