How to Disassemble Wuling Light Intake Branch Control Valve

Dismantling method of Wuling Light intake manifold regulating valve: shut down the car, disconnect the negative terminal of the battery, open the hood, first remove the manual maintenance switch, electronic throttle body and temperature sensor, then remove the clamp that fixes the intake pipe one by one, remove the intake pipe, remove the screws on the intake manifold assembly, and remove the regulating valve.

Damage to the control valve of the intake branch pipe will cause insufficient intake pressure, insufficient combustion, poor mixing ratio and invalid speed increase. ?

Treatment method of regulating valve

1, cleaning method. Welding slag, rust and molten slag in the pipeline cause the throttle valve, guide position and balance hole of the lower valve cover to be blocked or stuck, resulting in strain and abrasion of the curved surface and guide surface of the valve core and indentation of the sealing surface. This often happens in the initial stage of new operating system and after overhaul. This is the most common fault.

In this case, it must be disassembled and cleaned, and the slag should be removed. If the sealing surface is damaged, it should be ground. At the same time, open the bottom plug, and flush the slag falling into the lower valve cover from the balance hole, and flush the pipeline. Before putting into operation, let the regulating valve fully open and the medium flow for a period of time before putting into normal operation.

2. External scouring method. When some media which are easy to precipitate and contain solid particles are adjusted by ordinary valves, they are often blocked at the throttle and guide, and the flushing gas and steam can be externally connected at the bottom plug of the lower valve cover. When the valve is blocked or stuck, the external gas or steam valve can be opened, and the flushing work can be completed without moving the regulating valve, so that the valve can work normally.
