-、Product Name
Jiefang Sailong quick-release valve truck air brake rapid exhaust valve
Second, actual product photography parameters
1. Material: High-strength die-cast aluminum alloy valve body, pressure-resistant and corrosion-resistant
2. Interface Identifier: IN air intake, dual OUT air outlet, original vehiclePipe alignment
3. Matching packaging: original factory-style accessory packaging box, two per boxOptimization for assembly and maintenance
4. Application: Special exhaust valve for the rear wheel brake circuit
Three. Compatible Vehicle Models
Compatible with the full range of medium-duty trucksfrom Jiefang Sailong, including air-brake versionssuch as Sailong grille trucks, vans, flatbed trucks, andcargo trucks, as well as original factory componentsfor the rear wheel braking system.
Four. Working Principle
1. Step on the brake
Compressed air enters the valve body through theIN inlet, pushes open the internal diaphragm toblock the exhaust port, and the airflow flows fromthe two OUT outlets to the rear wheel brakechamber, enabling the wheels to achieve braking.
2. Release the brake
The air pressure at the intake end disappears, theinternal diaphragm rebounds, and the high-pressureinternal gas from the rear wheel is rapidly dischargedfrom the quick release valve body, eliminating theneed to return along the original long air tube routesignificantly reducing the braking return time.
Five. Core Product Advantages
Rapid pressure relief and exhaust, resolve the issueof delayed braking return, eliminate dragging brakes,abnormal overheating of brake pads, and abnormalwear. Improve the braking desynchronization andbrake deviation faults of both left and right wheelsThe aluminum alloy body is high-pressure resistant,vibration-resistant, aging-resistant, and has a longservice life
Original vehicle hole size, no need for piping modification,installation replacement, excellent sealing performance,resistant to air leakage and pressure relief during long-termuse
Six. Fault Detection (When Should the quick release valve be replaced)
1. After the brake is applied, the vehicle’s brake rebounds slowly, sinks, and moves forward.
High driving resistance
2. The brake pads frequently overheat, wear out too quickly,and cause an unexpected increase in fuelconsumption
3. The valve body experiences air leakage, Unusual exhaust noise after parking
4. Inconsistentleft rightleft right force of the brake,causing the brake to be off-center
5. Hanging // Wheel Rotation Division
