What Does a Vias Control Solenoid Valve Do?

Flow path control solenoid valve is one of the key hydraulic system components in construction machinery, its role is to control the flow of liquid, so as to realize the movement and operation of mechanical parts. This article will introduce in detail the function of the flow control solenoid valve and the wide application in the construction machinery.

 

Principle of operation

The core component of the flow path control solenoid valve is the solenoid coil, which is usually located on the outside of the valve body. When the current passes through the solenoid coil, it generates a magnetic field, and the strength and polarity of this field depends on the size and direction of the current.

 

A flow path control solenoid valve usually consists of a body and a spool. The body contains the passageway for the liquid to flow through, and the spool is located in the passageway. The spool is a movable part that moves up and down inside the valve body.

 

The operation of a flow path control solenoid valve is based on the principle of electromagnetism. It usually consists of a solenoid coil, a valve body and a valve spool. When current passes through the solenoid coil, it generates a magnetic field, and this field will affect the position of the spool. The movement of the spool will change the state of the liquid flow path, which can open or close the passage of the liquid to achieve flow or stop to match the operation of other diesel engine parts and starter motor.

 

Flow path control solenoid valve usually has two states, namely open and closed state. When not energized, a spring or other mechanical component will usually hold the spool in a specific position, which is when the valve is closed. When the solenoid coil is energized, the action of the magnetic field will overcome the force of the spring or mechanical component and move the spool to another position, thus opening the valve.

 

By changing the position of the spool, a flow path control solenoid valve allows for the control of fluid flow. In a hydraulic system, this means that the flow direction, flow rate and pressure of the fluid can be changed to enable the movement and operation of different mechanical parts.

 

Controlling fluid flow

Unlike a diesel solenoid valve, the main function of a flow path control solenoid valve is to control the flow of fluid through a hydraulic system. In construction machinery, hydraulic systems are used to control the movement of mechanical parts, such as lifting and lowering, telescoping and rotating. Flow path control solenoid valve realizes precise control of mechanical parts by changing the flow direction and flow rate of liquid.

 

Application Scenarios

These solenoid valves have a wide range of applications in construction machinery, the following are some common application scenarios:

 

Excavators: In excavators, runner control solenoid valves are used to control the expansion and contraction of hydraulic cylinders, thus controlling the lifting and tilting of the bucket, as well as the expansion and rotation of the digging arm.

 

Loaders: Flow path control solenoid valves are used in the hydraulic system of a loader to control the lift and tilt of the bucket for loading and unloading operations.

 

Dozers: In dozers, runner control solenoid valves are used to control the lift and tilt of the blade for grading and bulldozing operations.

 

Elevators: Flow path control solenoid valves are also used in the hydraulic systems of elevators to control the raising and lowering of elevating platforms.

 

Concrete Pumps: In concrete pumps, runner control solenoid valves are used to control the flow of concrete to ensure precise concrete placement.

 

Summarize

Flow path control solenoid valves are indispensable components in the hydraulic system of construction machinery, and they realize the precise control of liquid flow through the principle of electromagnetism. This control is key to the operation and maneuverability of construction machinery, ensuring efficient and maneuverable machinery. Understanding the function and application of flow control solenoid valves is vital for professionals in the construction machinery field. Through these solenoid valves, construction machinery is able to realize a variety of complex movements and operations, increasing efficiency and precision.
