Problems solved by technology

[0007] However, with regard to Patent Document 3, the main body 100 formed with the gas supply port (L1) and the gas discharge port (L2) and the locking device 600 for preventing the floating body 500 from rising are separately separated, and the inlets for supplying gas are separated from each other. Separated, so it has the disadvantages of complex structure and high manufacturing cost

Abstract

The present invention relates to an overflow blocking apparatus for a tank lorry. More specifically, in order to automatically shut off an inlet valve when an excessive amount of oil which exceeds an upper limit for oil injection is injected, and at the same time to have a simple structure, to facilitate the manufacture, and to improve reliability on the opening / closing operation, is provided an overflow blocking apparatus for a tank lorry comprising an overflow sensor which is made by combining: a main body (10) having a first cylinder (11) and a second cylinder (12) formed therein, a first air supply passage (13) connected to a side of the first cylinder, and a first air discharge passage (15) formed at one side; a piston (20) having one end connected to a rod (21) and the other end elastically supported with a spring (22), and being capable of reciprocating in the first cylinder; a lower main body (30) connected to the main body and having a lot hole (31) therein and a second air supply passage (32) and a second air discharge passage (33) connected to the wall of the lot hole; a lot (40) capable of reciprocating in the lot hole and having a recessed groove (41) formed in one side of the outer surface; a tube (50) provided in the form of wrapping the outer side of the lower main body; and a float (60) provided to be lifted by buoyancy of oil in the tube (50).

Description

technical field [0001] The present invention is an improvement on the anti-overflow device for tank trucks in Korean Patent Application No. 2013-0068649 (applied on June 14, 2013). More specifically, it relates to a tank truck installed above. It is used to prevent the internal pressure from excessively rising by discharging the oil vapor inside the storage tank, and to temporarily stop the pump at the shipping site by cutting off the ground wire of the shipping site when excessive oil is injected to exceed the upper limit of oil injection. Anti-overflow device for tank trucks. Background technique [0002] In general, an opening unit is formed in the inner space of a storage tank of a tank car for transporting oil or chemicals, and a critical point display point showing the maximum loading capacity is formed on the inner side of the opening unit, and is formed on each of the bottom surfaces of the inner space. An oil supply valve is provided on the installation port. [0...
