Tractor steering valve


Steering valve is a common control valve that is widely used in a variety of industrial and civil equipment. It controls the flow and direction by changing the channel of the fluid, enabling precise control of the system. The working principle of the steering valve mainly includes two aspects: structure and control. The steering valve structure consists of a valve body, a spool, a seat and a transmission mechanism. The valve body is the housing of the steering valve and is used to secure and support other components. The valve spool is the main control component of the steering valve and changes the shape and size of the fluid passage by moving the position of the valve spool. The seat is a sealing part between the spool and the body, which acts to prevent fluid leakage. The transmission mechanism is used to transmit external forces and control the movement of the valve core. There are many different ways to control the steering valve. Common control methods include manual control, electric control and hydraulic control. Manual control is a manual operation to change the position of the spool to adjust the fluid path. Electric control is the use of electric motors to drive the transmission mechanism to achieve remote or automatic control. Hydraulic control is to control the movement of the valve core through the pressure provided by the hydraulic system to achieve high-precision and high-efficiency control.


Steering of the tractor:

1. Handle steering

Handle steering is a common type of steering that is usually applied on older tractors. This steering method uses a mechanical traction transmission, which controls the steering of the wheels by pulling the handle to change the tension of the steering chain. However, due to the limited flexibility and accuracy of the handle steering, it is not suitable for all models of tractors.

2. Steering wheel steering

Steering wheel steering is a modern tractor steering method, which generally uses hydraulic or mechanical transmission to change the direction of the wheels by turning the steering wheel, so as to control the direction of the tractor. Compared to lever steering, steering wheel steering is more precise and convenient.

3. Hydraulic steering

Hydraulic steering is a way to control the steering through the hydraulic oil pipe, which uses a hydraulic pump to provide power to the steering cylinder, and controls the steering direction and pressure of the oil by controlling the steering valve, so as to control the steering of the tractor. Compared with mechanical steering and handle steering, hydraulic steering has the advantages of sensitivity, convenience and high accuracy.


There are many ways to steer a tractor, and when choosing a tractor, you need to consider different steering styles based on factors such as reliability, flexibility, and accuracy.
