Hydraulic systems used to perform useful work are widely used in stationary and mobile equipment. To control the flow of the working fluid directed to the mechanisms, a throttle with a non-return valve is used, which:
- Allows you to adjust the movement of the liquid in the desired direction.
- Ensures its free passage in the opposite direction.
- It combines the functionality of a check valve and a classic throttle valve.
Simple in design, they consist of a steel body that is resistant to the effects of chemically active media, a throttling and cross-sectional element of the working chamber and a check valve.
The principle of operation
The throttle with a non-return valve is installed directly into the pipeline of the hydraulic system. The unit has an inlet and outlet for a standard threaded connection to tubes or hoses. The principle of operation:
- · In a given direction, the liquid passes through an adjustable throttling hole, which allows the operator to manually change its speed using a valve located on the housing.
- · In the opposite (return) direction, the valve opens at a certain pressure of the working fluid, which ensures the free passage of hydraulic fluid without throttling.
Aggregates with a similar principle of operation are widely used in such areas as:
- · Machine and machine tool engineering — used to control the speed of movement of hydraulic cylinders in pressing hydraulic equipment and in machine tools.
- · Agriculture — the hydraulic principle allows effortless maintenance of attachments for tractors and combine harvesters.
- · Construction equipment — a wide variety of excavators, cranes, wheeled and tracked bulldozers.
- · Road transport — steering, braking and suspension systems of trucks or special equipment.
Pumping and hydroelectric power plants — hydraulics allow you to adjust the flow rate of the liquid.
