Abstract
The utility model discloses a valve coded lock which comprises a flange pipe, an inner layer lock mechanism arranged in the flange pipe, an outer sleeve in which the flange pipe is installed, and an outer layer lock mechanism arranged in the annular space between the flange pipe and the outer sleeve. The inner layer lock mechanism is directly connected with an oil flow channel of an oil tank, and is not only an inner lock, but also is a control valve. The outer layer lock mechanism is connected with the outer sleeve and the flange pipe, and is not only an outer lock, but also is a protective layer of the flange pipe, thereby the inner layer and the outer layer form a double layer six-level antitheft barrier, thereby being firm and durable, the antitheft effect is excellent, the utility model can be widely utilized on the antitheft parts of the oil tanks in fields or peripheral regions, and can also be utilized in similar antitheft places.
Description
One, technical field
The utility model relates to lock, particularly a kind of tank valve cipher lock.
Two, background technique
At present, the burglarproof lock that uses on the on-the-spot oil storage tank of petroleum production is a kind of traditional pellet shot from a slingshot copper core lock basically, and its structure is the inner screw plug and the copper core bullet lock master of device six ribs in the flanged pipe.Its objective is and prevent that jar interior oil product is stolen.But this lock is very easily pried open or is destroyed by the oil stealer, and people's property and national economy are suffered a loss, and also often causes environmental pollution.
Three, summary of the invention
The technical problem that the new shape of this practicality will solve provides and a kind ofly can overcome and avoid the shortcoming and defect of above-mentioned prior art and have double-deck lock construction, six grades of antitheft valve cipher locks, valve forms one with lock, make stealer be difficult to pry open, be difficult to destroy, take precautions against the stolen and problem of environment pollution caused of oil well.
The technological scheme that the utility model is dealt with problems is: comprise the valve cipher lock of flanged pipe, device internal layer latch mechanism has outer sleeve on the flanged pipe in flanged pipe, device outer lock mechanism in the annular space of outer sleeve and flanged pipe.The internal layer latch mechanism by pin rod, pole, bearing pin on valve body of valve plate, valve seat, valve body and device, bump sheet, spring and cover plate and form.The outside thread of valve body is meshed with the internal thread of flanged pipe, by pin rod valve body is locked mutually with flanged pipe.Outer lock mechanism is made of outer sleeve, grid, slide plate, hyoplastron and regulating lever, sliding sleeve, lining and plug.Grid and blue pipe are connected as a single entity, and slide plate and outer sleeve are connected as a single entity, and slide plate and grid are the push-and-pull transition fit, and hyoplastron does that by regulating lever outer lock mechanism opening, locked straight line are moved between slide plate and grid.
The internal diameter of valve body is the tubular structure of reducing, its outside thread is meshed with the internal thread of flange, has pin rod to bump sheet mechanism on the valve body, and an end of pin rod inserts in the circular groove of flanged pipe by valve body, the other end connects together by cutting axle and pole with bumping sheet, and its top withstands on the spring.One end of valve body connects valve seat, and valve seat and valve ball flexibly connect, and valve ball matches with the middle through hole of the blue pipe of valve, sealing mutually, and the other end and the cover plate of valve body are connected as a single entity.Cover plate is a tubular body, and one end internal diameter is the inner sleeve structure of 90 ° of cruciform vent and eight ribs, 24 limit evaginations, and the other end is a tubular body.The opening that cooperatively interacts is arranged on grid, hyoplastron and the slide plate, and hyoplastron makes outer lock mechanism opening, locked straight line move between slide plate and grid.Regulating lever is screwed in the screw of grid, one end device sliding sleeve, and hyoplastron fork and sliding sleeve flexibly connect, and an end of regulating lever is connected with hyoplastron, and the other end is a hexgonal structure.Plug one end has outside thread to be meshed with the internal thread of lining, and the other end is a triangular structure.Internal layer latch mechanism and outer lock mechanism have formed bilayer of the present utility model, six grades of antitheft barriers, use special tool can open or locked internal and external layer latch mechanism, open or close valve then.
The utility model following advantage of having compared with background technique:
1, the utility model adopts double-deck six grades of theft-prevention structures, and theftproof performance is superior:
Bilayer is promptly: have internal layer latch mechanism and outer lock mechanism, six grades are promptly antitheft:
One-level: lining constitutes with the plug with triangular structure;
Secondary: the top is hexagonal regulating lever structure;
Three grades: regulating lever and screw constitute password, and this password can be adjusted and change at any time, the regulating lever rotating cycle is set is this password.
Level Four: the cover plate on the valve body is the inner sleeve structure of 90 ° of eight ribs, 24 limit evaginations;
Pyatyi: the last hole of valve body cover plate is that the inner sleeve on " ten " font structure and eight ribs, 24 limits constitutes one;
Six grades: bump sheet pin rod mechanism on the valve body, when free state, under spring action, pin rod inserts in the circular groove of flanged pipe, valve body and flanged pipe are locked together, and when inserting special spanner, depress and bump sheet, mention pin rod, screw off valve body, valve is promptly opened, on the contrary throttle down then.
2, adopt valve and lock to constitute the structure of one, pick-proof, preventing destructing performance are superior.
3, anti-theft cipher is difficult for losing, even lose, also can reset new password immediately, guarantees the theftproof performance of locking.
Four, description of drawings:
Fig. 1 is the utility model embodiment sectional view;
Fig. 2 is the A-A sectional view of the utility model Fig. 1.
Five, embodiment:
Shown in Figure 2 as Fig. 1, can implement valve cipher lock of the present utility model well, below in conjunction with concrete auspicious the stating of accompanying drawing:
As Fig. 1, interior spiral shell on the flanged pipe 1 is meshed with the outside thread of valve body 12, one end of valve body 12 is connected with valve seat 3 with bolt 6, valve seat 3 usefulness bayonet locks 4 flexibly connect with valve ball 2, valve ball 2 matches with the middle through hole of flanged pipe 1 and seals mutually, also be the oil flow control valve of oil tank, mobile valve 12 can open or close oil flow channel.On the inwall of flanged pipe 1 circular groove is arranged, strengthening sleeve 5 is arranged on the outer wall of circular trough correspondence.Symmetry is installed pin rod and is bumped sheet mechanism on the valve body 12, and pin rod 8 one ends insert in the circular groove of flanged pipes 1 by valve body 12, the other end with bump sheet 11 and connect together by bearing pin 9,10 and pole 28, its top withstands on the spring 7.The other end of valve body 12 and cover plate 27 are connected as a single entity, cover plate 27 1 ends are "+" font endoporus and 90 ° of inner sleeve structures of eight ribs, 24 limit evaginations, open or close the internal layer latch mechanism with special tool, the other end is a tubular body, the annular space device oil sealing 25 and the gland 26 of itself and flanged pipe 1.One end of flanged pipe 1 is a flange plate, is connected with the oil tank flange plate, and the other end has interior step, and gland 26 and oil sealing 25 devices are on its step.
