Abstract
An burglar alarm of an oil well sleeve is composed of two parts, namely a lock and a sealing member, wherein the lock is vertically welded to a housing, thereby forming a T-shaped cylindrical combined structure; a connecting rod penetrates through an upper end cover, a sealing packing box, a separation flange and the center of the sealing packing to reach the interior of the housing, and the bottom end of the connecting rod is fixedly connected to a cam located between a baffle plate and a bush; the upper end of the connecting rod is a square or hexagonal structure; four coded lock blocks are located at the peripheral part of a lock cylinder with a lifting ring; the coded lock blocks are clamped in an annular groove formed on the upper part of the lock and a four-digit code can be set; a center hole is formed at the left end of the piston-shaped bush and four overflowing holes are formed outside the center hole; a three-step through hole is formed on the housing; internal threads are arranged at the left part of the three-step through hole, and a porous plate, a sealing gasket and a bush are sequentially mounted in the through hole from right to left, and then held down by a compression ring with external threads; a center rod penetrates through the center of the bush; a spring penetrates through the right end of the center rod, while the right end of the center rod is fixedly connected to a ball sealer; the ball sealer blocks the porous plate; and a nut at the left end of the center rod holds down the baffle plate. Besides, a clamp is arranged at the left end of the housing.
Description
Technical field
the utility model relates to oil field well casing oil anti-theft tool technology, particularly is a kind of oil well casing alarm.
Background technology
The sleeve gate of
oilfield oil well use at present is installed in the well head big four outside, is used for sealing oil jacket space and extraneous passage.In case sleeve gate is opened, the crude oil that accumulates in the sleeve pipe can flow to ground under the effect of bottom pressure.Because the oil well casing gate also will often use when measuring casing pressure or liquid level data, so can not shut.Owing to there is not anti-theft measure, make the lawless person that opportunity arranged, often steal crude oil from sleeve valve, this behavior has not only caused the crude oil loss to the oil field, and can cause the well site to pollute, even also can cause the shaft bottom to shake out causing the lie fault of well of sand card.
Summary of the invention
The purpose of
the utility model is exactly the above-mentioned defective that exists to prior art, designs a kind of oil well casing alarm.
The utility model is realized by following technical proposals:
the utility model is made up of lock body and seal two parts, and lock body part comprises: drop handle, lock core, password lock dog, lock body, upper end cover, sealed stuffing box, connecting rod, separated orchid, airtight and watertight padding, cam.Seal partly comprises: orifice plate, ball sealer, spring, housing, sealing mat, lining, pressure ring, baffle plate, nut, center-pole, clip head.Its lock body is vertical with housing to be welded, and is " T " shape cylinder combining structure; Connecting rod passes upper end cover, sealed stuffing box, at a distance from blue, airtight and watertight padding center, to enclosure interior, the bottom be fixedly connected with cam between the lining at baffle plate, be four directions or hexagonal structure on the connecting rod, be convenient to the special spanner switch.The center of lock core is provided with drop handle, and quadruplet password lock dog is positioned at lock core surrounding edge portion, and lock dog is stuck in the cannelure on lock body top, and four passwords can be set.
Lining in
above-mentioned oil well casing alarm is piston-like, and left end is provided with centre bore, and centre bore is provided with four flowing holes outward.
Housing center in
above-mentioned oil well casing alarm is provided with three grades of ladder holes, and left half is provided with internal thread, and the centre is equipped with orifice plate, sealing mat, lining from right to left successively, compresses by being provided with externally threaded pressure ring.Center-pole passes from the lining center, and center-pole the right is installed with spring, and right-hand member is fixedly connected with ball sealer, and ball sealer is sealed orifice plate, and center-pole left end nut is pushed down baffle plate.The housing left end is provided with the clip head, is convenient to use clamp connection with the well head sleeve gate.
The beneficial effect of
the utility model is: simple in structure, attended operation is convenient, can be used for open flow control behind oil, well sleeve pipe oil, natural gas antitheft, the metering room station, substitutes the shut-in well blind plate.Coded lock can't be opened under the situation of no password, prevents that effectively crude oil, natural gas are stolen, improves oil field comprehensive regulation level.
