Product representation

1, structural design

Double design of pipelines: there are inflatable pipelines and brake control pipelines, inflatable pipelines are often inflatable and usually red; Brake control pipelines remove the air of the brake signal air when pressed the main brake and often yellow.

Multicapled control: the front, medium and rear main brakes and the parking brake valve are controlled, some models are also equipped with a separate valve of the manual brake of the trailer, through the two -way check valve and the output of the main brake valve to control air pressure parallel control.

2, the principle of work

Normal work: with normal movement, the inflatable line is inflated through the inflatable connector and the outlet valve of the trailer brake to inflate the trailer brake tank. When the main car slows down, the air pressure signal in the brake control line makes the trailer brake valve work, opening the road between the air trailer and the brake compartment to achieve synchronous braking. When the brake of the main car is released, the air pressure control valve in the brake control line is empty, the air from the trailer brakes exits through the trailer brake valve, and the brake is released.

Elimination of malfunctions: if the gas line is damaged or flows to a certain extent, the brake valve of the trailer automatically switches to the brake position. When the brake control line is damaged or flows, the normal movement of the main vehicle will not have any effect. When the main car slows down, the brake valve of the main car automatically overlaps the inflatable pipeline, and the braking synchronized with the main car will be created automatically through the brake valve of the trailer.

3 、 Functional configuration

The load adjustment function: some Haworth trailers are equipped with a manual load control valve with three “without load”, “half load” and “full load” provisions, which can regulate the trailer braking force and improve the anti -lock effect of the trailer. The effect of braking.

The brake unlock function: there is an unlock valve, when the trailer is disconnected from the main vehicle and it must be moved, the brake can be unlocked manually.

Connection to the system

It works with a double -circuit main brake system, a spring energy drive and a parking brake, an emergency braking system and an auxiliary brake system of exhaust gases to ensure the reliability and safety of inhibition of the entire vehicle.

Below is a more common method for installing the sinotruk trailer control valves. Products of different models and specifications may vary slightly. Please read the operating manual and appropriate technical information for actual operation:

Preparation

Confirmation of products and tools: check if a new model of the Sinotruk trailer control valve is compatible with the vehicle, and also make sure that its appearance is not damaged, and the details are whole. Prepare the tools necessary for installation, such as wrenches, screwdrivers, sealants (as necessary), tools for connecting gas pipes, etc.

Safety measures when driving a car: Parke the car on a flat, solid and safe surface, turn on the parking brake and set the warning signs to prevent accidental movement of the car. Turn off the engine and disconnect the main circuit breaker of the car to eliminate the accidental turning on the electric system due to improper operation during installation.

Clean the installation location: thoroughly clean the installation site of the control valve, remove dust, oil, rust and other contaminants from the surface, and also make sure that the installation surface is even and clean to ensure tightness and stability after installation.

Set the control valve body.

Fasten the control valve: install the control valve of the trailer to the expected installation location and securely fix it on the vehicle using suitable bolts, nuts or other fasteners. Make sure that the fasteners are tightened with the specified moment to prevent the weakening or displacement of the control valve during the movement of the car.

Connect the air ducts: correctly connect the air ducts in accordance with the air system circuit and the interface label on the control valve. As a rule, interfaces with various functions have the corresponding marking (for example, an input for air, output for air, control port, etc.). When connecting the air tube, make sure that it is inserted into place, and securely fix it with a clip for an air tube or other connecting device to prevent air leakage. For some interfaces that need to be sealed, you can apply the corresponding amount of sealant before the connection to improve sealing.

Connection and check of the gas line

Connection of the gas circuit: In accordance with the design of the gas circuit system, correctly connect the control valve to the trailer to the fuel tank of the vehicle, the brake valve, the interface of the gas circuit of the trailer and other related components. Make sure that the gas line is reliably connected, without twisting, excesses or blockages to provide a smooth flow of gas.

Verification check: After the connection of the gas line is completed, turn on the gas source switch to pump up the gas system to normal working pressure. Then apply soap water or other suitable fluid to detect leaks on all ducts of the ducts, sealing parts of the regulatory valves and other places where there may be leaks, and check if there are bubbles. If the leak is detected, immediately redraw the gas source, re -check the connection and repair it until the leak in all parts of the gas connection is eliminated.

Functional testing

Preliminary test: Having made sure that the gas line is connected correctly and there are no leaks, start the car engine and let the gas line system achieve normal working pressure. Then use the pedal of the brakes of the vehicle, the hand brake valve and other relevant controls, check the working condition of the trailer control valve and the presence of extraneous sounds, vibrations or air leaks.

Brake test: conduct the brake test in a safe place, and first conduct the brake test only on the vehicle to make sure that the vehicle itself is in the normal efficiency. Then connect the trailer for the combined brake test to check whether the trailer control valve can accurately control the trailer brakes and whether the brake effect meets the requirements. During the test, pay attention to parameters such as a change in air pressure during braking and the brake operation time to make sure that the trailer control valve is normal.

Completion of installation and finishing

Fix the air ducts and components: place and fix the connected air ducts, as well as use cable screeds or other fasteners to fix the ducts in the appropriate position to prevent their friction, tension or squeezing during the movement of the vehicle.

Clean the installation site: after the installation is completed, clean the installation site, remove the tools and the remaining parts and maintain cleanliness at the workplace.

If you have difficulties or uncertainty during installation, it is recommended that you contact the vehicle operating manual or consult professional technical specialists or in the Sinotruk company after -sales service.
