A quick release valve, also known as a QR valve, is a type of air brake valve commonly used in heavy-duty vehicles such as trucks, buses, and trailers. It is a safety device that allows for the immediate release of air pressure from the brake system in case of an emergency or when the vehicle needs to stop quickly.
Features of Quick Release Valve
Piston Mechanism: The quick release valve uses a piston mechanism to control the flow of air in the brake system. When the brake pedal is released, the valve closes, preventing air from escaping from the brake system.
Emergency Release: The QR valve has an emergency release feature that allows for the quick release of air pressure from the brake system in case of an emergency. This feature helps to prevent accidents by allowing the driver to stop the vehicle quickly.
Pressure Regulation: The QR valve also regulates the air pressure in the brake system to ensure that it is within safe operating limits. If the pressure in the brake system exceeds the safe limit, the valve will release air to bring it back to a safe level.
Benefits of Using Quick Release Valve
Safety: The primary benefit of using a quick release valve is safety. It allows for quick and effective braking in case of an emergency or when the vehicle needs to stop quickly.
Durability: QR valves are made of high-quality materials that are designed to withstand the rigors of heavy-duty use. They are built to last and require minimal maintenance.
Easy to Use: Quick release valves are easy to use and operate. The emergency release feature is intuitive and can be activated quickly by the driver in case of an emergency.
The strategic goal of the factory: continue to research, develop and product the new air brake system components, expand the market, and gradually develop into an expert enterprise in the manufacturing of air control system components.
