JZ-7 series brake self-valve remote control system and operation method thereof

Abstract

The invention provides a JZ-7 series brake self-valve remote control system and an operation method thereof. The system comprises a self-valve, an equalization air cylinder and a relay valve. A normally-open electromagnetic valve is arranged on an equalization air cylinder pipe between the self-valve and the equalization air cylinder; a normally-open electromagnetic valve is arranged on a middle average pipe between the self-valve and the relay valve; a normally-open electromagnetic valve is arranged between the self-valve a main air blocking pipe of and the relay valve; a normally-closed electromagnetic valve is arranged between the middle average pipe at the relay valve end and a train pipe; a normally-closed electromagnetic valve is arranged between the equalization air cylinder pipe atthe equalization air cylinder end and the middle average pipe at the end of the relay valve; a pressure transmitter is arranged on the equalization air cylinder; a normally-closed electromagnetic valve is arranged between a main air cylinder pipe and a sanding relay; an electric air release electromagnetic valve is arranged on the train pipe; and a normally-closed electromagnetic valve is arranged at the main air blocking pipe and the main air cylinder pipe at the end of the relay valve. Through improvement, the stage braking of the train by the remote control locomotive controlled by the self-valve is realized, and the braking performance of the remote control locomotive is improved.

Description

technical field [0001] The invention belongs to the field of electromechanical automation, and in particular relates to a JZ-7 series brake self-valve remote control system for diesel locomotives or electric locomotives and an operating method thereof. Background technique [0002] At present, the routine operation of locomotives is controlled by the driver in the cab, including locomotive loading, speed regulation, auxiliary control, braking, etc. Due to the special on-site operating environment and the increase in labor costs of various enterprises, some enterprises have studied The remote control mode of the locomotive is used to control the locomotive, which can meet the conditions of narrow work area, open work area, and one-person operation. However, the commonly used method for locomotive braking is to control the single valve. In special cases, the emergency valve can be realized. brake. But the single valve can only brake the locomotive separately, and the braking ...

AI Technical Summary

Problems solved by technology

But the single valve can only brake the locomotive separately, and the braking force is relatively low, so the emergency braking realized is to make the whole train come to an emergency stop.

However, remote control is between single valve braking and emergency braking, and there is no suitable braking system and braking method in the prior art.
