Product Description

Product internal structure and working principle

Excavator hydraulic control valve is an important part of excavator hydraulic system, which plays a key role in regulating hydraulic oil flow and pressure. A thorough understanding of the internal structure and working principle of the hydraulic control valve is helpful to understand the operation mechanism of the excavator hydraulic system.
First, the internal structure of the hydraulic control valve:

Reversing spool: It is the core component of hydraulic control valve, which changes the channel of hydraulic oil by moving up and down and left and right to achieve the control and adjustment of hydraulic system.
Spring: Used to control the position of the reversing spool to ensure that the hydraulic control valve returns to a neutral position when it stops working.
Spool guide sleeve: fixed the position of the reversing spool to ensure its accurate movement during the working process, and with the hydraulic control valve housing to form a sealing structure.
Hydraulic control valve shell: is the shell of the hydraulic control valve, and there are multiple oil holes and connecting ports inside, so that the hydraulic oil flows in the valve to achieve the control of the hydraulic system.
[Two, the working principle of hydraulic control valve] :
Hydraulic control valve according to the flow direction and pressure of hydraulic oil to achieve the control and regulation of the hydraulic system, its working principle is as follows:

Oil supply stage:
a. The hydraulic pump draws the hydraulic oil from the tank and transmits it to the hydraulic control valve through the hydraulic pipeline.
b. The reversing spool of the hydraulic control valve adjusts the channel of the hydraulic oil according to the operator's operation, so that it enters the hydraulic rotary motor or other hydraulic actuators.
Control stage:
a. Hydraulic control valve according to the flow direction and pressure of hydraulic oil, to achieve the control of hydraulic rotary motor and other hydraulic actuators.
b. The spool guide sleeve and spring in the hydraulic control valve guide and control the spool movement, ensure the smooth flow of hydraulic oil, and achieve the stable work of the hydraulic system.
Oil return stage:
a. After the hydraulic rotary motor and other hydraulic actuator work, the hydraulic oil returns to the hydraulic control valve.
b. The reversing spool of the hydraulic control valve adjusts the channel of the hydraulic oil according to the flow direction of the return oil, so that it flows back to the tank and completes a working cycle of the hydraulic system.
With its precise internal structure and efficient working principle, the excavator hydraulic control valve realizes the precise control and stable adjustment of the excavator hydraulic system. Its flexibility and reliability provide a strong guarantee for the efficient operation and safe operation of the excavator. During the operation of the excavator, ensure the normal operation of the hydraulic control valve to ensure the smooth operation of the excavator and extend the life of the equipment.

Product operation manual

Thank you for choosing our excavator hydraulic control valve products! In order to ensure that you can correctly operate the hydraulic control valve during use and ensure the efficient operation of the hydraulic system, we have prepared this operation manual for you. Please read this manual carefully before use, and perform operation and maintenance according to the guidance.

1. Hydraulic control valve overview

The excavator hydraulic control valve is the key component of the excavator hydraulic system, which is responsible for controlling the hydraulic flow direction and pressure, adjusting the working state of the hydraulic system, so as to achieve the precise control of various actions of the excavator.

2. Safety precautions

Before operating a hydraulic control valve, be sure to follow the following safety precautions:

Make sure the excavator is in a safe and stable working condition and stop the engine.
When inspecting and maintaining the hydraulic control valve, close the main valve of the hydraulic system and ensure that the hydraulic pressure has been released.
When operating the hydraulic control valve, do not touch the hydraulic valve or its nearby moving parts with your hands to avoid accidental injury.
When operating hydraulic control valves, focus on the job and avoid distraction or fatigue.
3. Operation method of hydraulic control valve

Before starting the excavator, ensure that the following steps have been completed:

Turn on the main power supply of the excavator and confirm that the hydraulic oil level is within the normal range.
Check the hydraulic oil temperature to ensure that it is within the normal operating temperature range (usually -20°C to +80°C).
Start the engine and let it warm for a period of time until the hydraulic oil temperature rises to the normal working range.
Operating hydraulic control valve:

According to the actual work requirements of the excavator, the control rod or button on the hydraulic control valve is operated to control the hydraulic flow direction and pressure.
In the operation process, pay attention to the working state of the hydraulic system, such as hydraulic pressure, flow and other parameters, to ensure that it operates within the normal range.
If you find that the hydraulic control valve is abnormal or the hydraulic system has a problem, please stop using immediately, and check and repair.
4. Maintenance method of hydraulic control valve

Regular maintenance of the hydraulic control valve can ensure its normal operation and extend its service life. Here are some suggested maintenance methods:

Check the seals and connectors of the hydraulic control valve regularly, and replace them in time if they are damaged.
Clean the hydraulic control valve regularly to avoid sediment and debris entering the valve body, affecting the flexibility of the valve.
Pay attention to the cleaning and replacement of hydraulic oil to ensure that the hydraulic oil in the hydraulic system meets the specified quality standards.
Check and adjust the hydraulic control valve regularly to ensure that it operates in normal working condition.
Thank you for reading our Excavator Hydraulic control Valve operation manual. If you encounter any problems in the process of use, please contact us in time, we will be happy to provide you with technical support and service.

Wish your excavator work smoothly, safely and efficiently!
