Valve control unit of tank lorry

Abstract

Disclosed therein is a valve control apparatus for a tank lorry. The valve control apparatus for the tank lorry includes a first control valve for opening and closing the oil feed valve by supplying compressed air to the oil feed valve or discharging the supplied compressed air to the outside, a second control valve for actuating the first control valve by the user's manual manipulation, an automatic closing valve for actuating the first control valve, a third control valve for selecting an operation of the automatic closing valve, and a pneumatic circuit for realizing functions of the control valves, wherein the control valves are general direction conversion valves for converting a flow of the compressed air and can be controlled on the road. So, a user can carry out a loading work in more convenient and safe when the user loads oil articles or chemicals on a storage tank mounted on the tank lorry.

Description

technical field [0001] The present invention relates to a valve control device for an oil tank truck, especially, a valve control device for an oil tank truck when oil products or chemicals are loaded in an oil storage tank installed on the oil tank truck , which can manually supply and stop the supply of the load by the user's direct operation of the valve control device, and when the supplied load reaches the maximum load, it can automatically complete the loading work, and can be activated by air pressure Without using any electronic equipment, therefore, convenience is provided in the work by automating the loading work, and safety is ensured because no electronic equipment is used. Background technique [0002] Such as figure 1 and figure 2 As shown, an oil tank truck for transporting loads such as oil products or chemicals includes: an oil storage tank 100 mounted thereon; a plurality of compartments adapted to divide the interior of the oil storage tank 100 into a ...

AI Technical Summary

Problems solved by technology

[0007] However, the above-mentioned general oil tank truck has some problems in that since the user has to perform the supply of the load by directly opening the opening 120 and checking the internal state of the oil storage tank 100 with the naked eye at the top of the oil storage tank 100, its Inconvenient handling; danger of explosion and fire when loaded with flammable materials such as oil; and possible environmental Pollution and user exposure to toxic chemicals

However, according to the improved valve control device using electronic equipment in the prior art, there is a problem that the safety cannot be ensured due to the electronic equipment, so users are reluctant to use the oil tanker. The structure is inconvenient to manufacture and use
