Abstract
The utility model discloses an oil discharge valve lock is designed for preventing to draw the oil tank car oil discharge gate valve to be opened wantonly, prevent crude oil loss's purpose, mainly including the dustproof protecting cover of connecting the lock body, establish nut cover, adjusting washer and the adjusting screw in the lock body, establish at the other lock core of nut cover side, establish radial logical groove etc. on nut cover barrel wall. During installation, a tank car oil unloading valve hand wheel and a gland nut are disassembled, a nut sleeve and a lock body are sleeved on an original lead screw, after the position is debugged, a key is inserted to rotate a lock core, so that a lock tongue slides into a radial through groove of the nut sleeve, and a dustproof protective cover is screwed on. The oil discharge valve lock has the advantages of simple structure, safety, reliability, low manufacturing cost and convenience in installation, the key can be used only by authorization, and the oil discharge valve lock can effectively prevent the oil tank truck from being opened randomly and prevent crude oil from running off.
Description
Technical field
The utility model relates to a kind of oil drain valve door lock, belongs to RTC unloading gate technical field.
Background technique
At present the production scene in long celebrating oil field is provided with many petrol station points that draw, and particularly the crude oil at outlying well station lean on the tank car roping substantially, uses traditional emptying gate valve of beating lead sealing method can not effectively stop the loss of crude oil.
Summary of the invention
The purpose of this utility model is to provide a kind of oil drain valve door lock, and this valve only has the authorized person to use, and can effectively prevent any unlatching of oil unloading of fuel tank car gate.
Concrete technological scheme of the present utility model is as follows:
The external connection dust-proof hood of cylinder-type lock is provided with the axial step hole in the lock body, attaching nut's cover in the hole enlargement hole, and the undergauge bore end is provided with adjusting washer (disk) and adjusting screw.The nut sleeve side is other to be provided with lock core, and lock core is fixed by the screw on the lock body.Establish seal washer in the nut sleeve, outer wall is provided with seal ring, and barrel is provided with the radially groove corresponding with lock core.
This oil drain valve's door latch structure is simple, safe and reliable, and low cost of manufacture is easy for installation, and key need be authorized and could be used, and " opening different locks with different keys ", can effectively prevent any unlatching of oil unloading of fuel tank car gate, stops crude oil to run off.
