Pneumatic operation and remote monitoring system for tanker filling and exhausting

Abstract

A tank car charging and discharging system belongs to railway tank car pneumatic operations and remotely monitored top loading and bottom unloading. The tank car charging and discharging system comprises a charging and discharging device disposed at the bottom of a tank car and an overcharge automatic protection device (9) disposed on the top of the tank car. During medium loading on the tank car, when the medium reaches a preset height, the overcharge automatic protection device (9) provides a signal for ground equipment, and ground operation personnel decide to turn on or turn off the charging and discharging device according to the signal. The tank car charging and discharging system is high in safety, strong in reliability, and good in accuracy.

Description

technical field [0001] The invention belongs to the technical field of tank car filling and discharging, and relates to a tank car filling and discharging device, in particular to a tank car filling and discharging pneumatic operation and remote monitoring system for railway tank car pneumatic operation and remote monitoring type loading and unloading device. Background technique [0002] With the rapid development of my country's economy and the gradual increase of international influence, China's railway wagon products have been fully upgraded. The current top loading and unloading or bottom loading and unloading devices are all controlled manually or hydraulically. With the maturity of pneumatic control technology, corresponding pneumatic operation products have also been developed for railway tank cars. The current structure and method of adding rows have the following defects: [0003] 1. The railway tank car loading and discharging devices are scattered and installed ...

AI Technical Summary

Problems solved by technology

[0003] 1. The railway tank car loading device is scattered and installed on the tank car. When the tank car encounters a collision or overturns by chance, these decentralized tank car control and protection components are easily damaged, and the safety and reliability are relatively poor.

[0004] 2. The medium filling and discharging system used on the railway tank car includes the oil filling and discharging port and an oil filling and discharging valve installed at the filling and discharging port. When loading or discharging the medium inside the tank car, the filling and discharging speed is slow , low work efficiency

For the oil filling and discharging valve seat, the currently adopted method is to directly open the oil discharge port at the bottom of the tanker, and a filter screen is provided at the opening and the connecting part (oil filling and discharging valve) of the filling and discharging valve, but when using pneumatic control After the valve is lowered, because the connection between the bottom of the filling and discharging valve and the valve seat is limited by the structure of the bottom of the filling and discharging valve, the bottom of the filling and discharging valve is thicker (there is a blind hole for connecting with the lowering and discharging valve), so it is directly shortened The distance between the oil filling and draining port at the bottom of the tanker and the oil filling and draining valve seat is shortened, the oil draining space is greatly reduced, the flow rate of the oil unloading port is significantly reduced, and the work efficiency is low
