What Is a Vent Control Solenoid?

An exhaust brake valve is installed between the exhaust pipe and the muffler, and this valve is used by trucks to control the internal combustion engine to stall.

When braking,

There are two commonly used brake valves: the brake valve used to control the braking and mitigation effect of all trains (including rolling stock) is called automatic brake valve.

One of the main components of railway brakes. The equipment installed on the locomotive to brake the entire train by the driver; the brake valve used to individually control the braking and mitigation of the locomotive is called a separate brake valve.

(1) Check the circuit

Focus on the inspection of the solenoid valve, remove the connection cable from the solenoid valve, and test the fire with the test lamp. If the light is on, there is electricity, and if you can still hear the sound of "thumb," then the solenoid valve is working normally, otherwise it is considered to be faulty.

(2) Check each switch

When checking the control switch, the main check is whether the power can be turned on and off in time. The third gear switch has three gears. In the middle position, the three and four cylinders of the engine act as a brake. In the lower position, the one, two, five, and six cylinders act as a brake. In the upper position, all six cylinders. Both act as brakes.

(3) Check the oil circuit

Connect the circuit, loosen a connector on the oil pipeline, and observe the flow of inorganic oil and the pressure. The inspection can be carried out in three steps ::

Check for faults at the check ball valve.

Check whether the main piston (injector rocker arm) works normally.

Check whether the auxiliary piston (exhaust valve) has oil flowing through it.

Check the working conditions of the main piston and the auxiliary piston. It is mainly to check whether the main piston or the auxiliary piston is rusted or stuck.
