Description
Technical Field
The utility model relates to the technical field of hydraulic control, in particular to a hydraulic control one-way valve.
Background
The hydraulic control one-way valve is an important accessory of the intelligent prestressed tendon tensioning system, the hydraulic control one-way valve is a valve which can enable the one-way valve to reversely circulate by controlling the pressure of fluid, and the hydraulic control one-way valve is different from the common one-way valve in that a control oil way is additionally arranged, when the control oil way is not communicated with pressure oil, the hydraulic control one-way valve works like the common one-way valve, and the pressure oil only flows from an oil inlet to an oil outlet and cannot reversely flow. When the control oil way is provided with control pressure input, the piston ejector rod moves under the action of pressure oil, the ejector rod is used for ejecting the one-way valve, so that the oil inlet and the oil outlet are communicated, and if the pressure of the oil outlet is larger than that of the oil inlet, the oil can flow reversely. However, the stroke of the ejector rod of the existing hydraulic control check valve is fixed, so that the opening and closing control of the check valve is inconvenient to adjust. To this end, the inventors propose a hydraulically controlled check valve.

Detailed Description
Example 1
Referring to fig. 1, in the present embodiment, the hydraulic control check valve includes a valve body 10 defining a first installation cavity 11 and a second installation cavity 12, a communication hole 13 is disposed between the first installation cavity 11 and the second installation cavity 12, a push rod 20 in the first installation cavity 11 passes through the communication hole 13 and abuts against a check valve 30 in the second installation cavity 12, a first oil path 14 communicated with the communication hole 13, a second oil path 15 communicated with the first installation cavity 11, and a third oil path 16 communicated with the second installation cavity 12 are disposed on the valve body 10, an adjusting bolt 40 screwed with the push rod 20 is disposed at an end of the valve body 10, and rotation of the adjusting bolt 40 can drive the push rod 20 to slide along the communication hole 13.
According to the embodiment, the existing hydraulic control one-way valve is optimized, the rotatable adjusting bolt 40 is additionally arranged, so that the ejector rod 20 can slide in the first mounting cavity 11, the purpose of adjusting the stroke of the ejector rod 20 is achieved, and the hydraulic control one-way valve has the advantage of accurate control.
In this embodiment, alternatively, the first installation chamber 11 and the second installation chamber 12 are arranged at intervals inside the valve body 10, and the first installation chamber 11 penetrates the left end face of the valve body 10, the second installation chamber 12 penetrates the right end face of the valve body 10, the first installation chamber 11 and the second installation chamber 12 are integrally configured in a coaxially arranged cylindrical shape, the communication hole 13 is formed between the first installation chamber 11 and the second installation chamber 12 for communicating the first installation chamber 11 and the second installation chamber 12, and the communication hole 13 is configured in a rectangular shape in cross section, and the communication hole 13 is integrally arranged on the axis of the first installation chamber 11.
