Description

The valve burglarproof lock

The utility model relates to the open-air antitheft a kind of valve burglarproof lock of producing of valve in oil field.

At present, in the oilfield process, crude oil and valve components are often stolen, often produce to the oil field and cause heavy losses.For this reason, post, oil field worker and engineers and technicians have carried out number of research projects, have taked various anti-theft measures, valve for guarding against theft for example, but because valve for guarding against theft cost cost height is to influence ordinary production with valve one now with its replacement, the 2nd, cause waste also impracticable to the production in oil field.

The purpose of this utility model is to provide a kind of and is not changing former valve mechanism, do not influencing under the ordinary production situation, in order to the valve burglarproof lock that prevents that crude oil loss and valve components from losing.

The utility model is achieved in that by shell 1, lock core support 2, lock core 3, dead bolt 4, snap close 5, locking bar 6, draw ring 7, locking bar support 8, protective sheet 9 to be formed, lock core support 2, locking bar support 8 are linked to be as a whole with shell 1, locking bar 6 inserts the center hole of locking bar support 8, snap close 5, lock core support 2, there is draw ring 7 locking bar 6 ends, and dead bolt 4 links to each other with lock core 3.

The utility model also adopts following technological scheme:

Shell 1 is columnar structured, and the outer end is circular cone " protruding " shape structure, and its center hole has groove less than interior bone on the shell 1.

The groove of being offered can be one, also can be more than one, and its shape can be a rectangular.

Lock core support 2 locking bar supports 8 are positioned at the inner end, bottom of shell 1, two supports are " L " shape, and the outer end, lateral part is cylindrical, and the center is not isometrical cylindrical hole, the inner end through hole is identical, and lock core support aperture, 2 outer end and length are all greater than locking bar support 8 outer end through holes.

Locking bar 6 is a circular arc for its inner end of round column structure, and there is one " recessed " shape circular groove in the termination.

Snap close 5 is a circle structure, and central through bore is identical with the through hole of locking bar support 8, lock core support 2, and is one with the valve body weldering.

Dead bolt 4 is the semicircle hook-type.

Protective sheet 9 is circular globoidal structure, on the axle and between the cambered surface little spring being installed, can overlap with lock core 3 end faces.

Advantage of the present utility model is: simple in structure, and highly versatile, easy for installation, do not influence ordinary production, can prevent effectively that crude oil and valve components are stolen.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a left TV structure schematic representation of the present utility model.

Below in conjunction with accompanying drawing the utility model is further described:

This valve burglarproof lock is made up of housing assembly, locking mechanism two parts.Housing assembly is positioned at top, and locking mechanism is positioned at the bottom, constitutes an integral body by locking bar 6 between the two.It is characterized in that housing assembly is made up of shell 1, lock core support 2, locking bar support 8, two stands and bottom, shell inner end are welded into as a whole; Locking mechanism is made up of protective sheet 9, lock core 3, dead bolt 4, snap close 5, locking bar 6, draw ring 7, and snap close 5 is welded into one with valve body, and locking bar 6 inserts locking bar support 8, snap close 5, lock core support 2 center holes, constitutes an integral body by dead bolt 5 lockings.

Shell 1 is columnar structured in the above-mentioned valve burglarproof lock, and the outer end is circular cone " protruding " shape structure, and center hole is less than interior bone, and shell 1 is offered 2～5 rectangular slots according to valve handle supporting number.Lock core support 2, locking bar support 8 are positioned at the outer casing bottom inner end in the above-mentioned valve burglarproof lock, two supports are " L " shape, the outer end, lateral part is cylindrical, and center hole is not isometrical cylindrical hole, the inner end through hole is identical, and lock core support aperture, 2 outer end and length are all greater than locking bar support 8 outer end through holes.Locking bar 6 is a round column structure in the above-mentioned valve burglarproof lock, and its inner end is the circular arc head, and there is one " recessed " shape circular groove in the termination, and external end head is a circular draw ring 7, and the end is " protruding " shape round platform.

Snap close 5 is a circle structure in the above-mentioned valve burglarproof lock, and central through bore and locking bar support 8, lock core support 2 inner end through holes are identical, and is one with the valve body weldering.

Dead bolt 4 links with lock core 3 in the above-mentioned valve burglarproof lock, and dead bolt 4 is the semicircle hook-type, opens and closes corresponding actions with lock core 3, thereby reaches the purpose of control locking bar 6.

Protective sheet 9 is circular globoidal structure in the above-mentioned valve burglarproof lock, on the axle and between the cambered surface little spring being installed, generally overlaps with lock core 3 end faces.Lock core 3 is played a protective role.

At first select suitable lock according to valve handle structure, size; The 2nd, locking bar 6, snap close 5 are taken off; The 3rd, from the valve handle center E groove on the shell 1 handed over to hold to handwheel and buckles, contact with the valve handle pressure cap up to the lock outer end, align with the A hole, then with locking bar 6 from locking bar support 8 center hole D, snap close center hole C, lock core carriage center hole B insertion; The 4th, weld as a wholely with valve body with snap close 5 is placed in the middle, promptly install; The 5th, key is inserted people's lock core 2 hole F, positive hour hands rotational lock core 2, hand is taken the photograph draw ring 7, promotes locking bar 6, makes dead bolt 4 relative with locking bar 6 end annular " recessed " grooves, can lock, and plays antitheft effect; Otherwise, can carry out open operation.
