Description

A kind of novel oilfield oil recovery valve for guarding against theft

Technical field

The utility model relates to valve for guarding against theft field more particularly to a kind of novel oilfield oil recovery valve for guarding against theft.

Background technique

During oil extraction in oil field, needed in pipe-laying process using to current limliting valve, valve central axis rotation is Oil liquid can be made to flow out, traditional Anti-theft valve, which mostly uses to cooperate at the top of the central axis of Idiotype with rotation key, plays antitheft work with this With, but because of its shape as it can be seen that being easy to be cracked, it is unfavorable to protect, and structure is not reasonable.

Utility model content

The utility model In view of the above shortcomings of the prior art, provides a kind of structurally reasonable novel oilfield of one kind and adopts Oily valve for guarding against theft.

The purpose of this utility model is to be achieved through the following technical solutions：

A kind of novel oilfield oil recovery valve for guarding against theft, including Anti-theft valve, U-shape lock lock body, the Anti-theft valve two sides are symmetrical Ring flange, ring flange top have lock pillar boss, and lock pillar boss outer symmetrical is distributed lock pillar, is uniformly distributed card slot inside lock pillar, There is valve central axis in the middle part of Anti-theft valve, there is central axis card slot in the middle part of valve central axis, lock pillar boss rear portion is welded with floor, There is lockset shell, the symmetrical lock pillar through-hole of lockset interior of shell in the middle part of the U-shape lock lock body, U-shape lock lock body inside has, Lock pillar is placed in lock pillar through-hole, and lockset shell is placed in central axis card slot, is cooperated with key, inside card slot and U-shape lock lock body The cooperation of key actuated card column.

There is rotation hexagonal boss, rotation hexagonal boss and die nut cooperate, and Anti-theft valve passes through at the top of the Anti-theft valve Ring flange and oil pipeline flanged joint.

Beneficial effect：

Lock pillar is placed in lock pillar through-hole, and key is inserted into lock pillar through-hole, by key actuated inside card slot and U-shape lock lock body Locking is played the role of in card column cooperation, and valve central axis internal symmetry distribution center axis card slot, two sides symmetrically lock two U-shape locks Lock body, central axis card slot and lockset shell cooperate, the rotatory force that valve central axis is subject to can be uniformly transferred by lockset shell to Lock pillar while playing anti-theft function, can prevent valve central axis from rotating, and make thief that can not carry out flow tune Whole, structurally reasonable, lock pillar rear portion is welded with floor, while playing connection function, can provide support for lock pillar boss, and Thickness is extended, prevents hydraulic shear from cutting lock pillar boss and is stolen, it is structurally reasonable.

Specific embodiment

The utility model is described in further detail below according to drawings and examples：

A kind of novel oilfield oil recovery valve for guarding against theft, including Anti-theft valve 01, U-shape lock lock body 02,01 two sides pair of Anti-theft valve Claim distribution ring flange 11, there is lock pillar boss 12 at the top of ring flange 11,12 outer symmetrical of lock pillar boss is distributed lock pillar 13, lock pillar 13 Inside is uniformly distributed card slot 14, has valve central axis 16 in the middle part of Anti-theft valve 01, has central axis card in the middle part of valve central axis 16 Slot 17,12 rear portion of lock pillar boss are welded with floor 15, have lockset shell 21, lockset shell 21 in the middle part of the U-shape lock lock body 02 Internal symmetry is distributed lock pillar through-hole 22, has 23 inside U-shape lock lock body 02, lock pillar 13 is placed in lock pillar through-hole 22, lockset shell In 21 merging central axis card slots 17,23 cooperate with key, and the key actuated card column inside card slot 14 and U-shape lock lock body 02 cooperates.

There is rotation hexagonal boss 18, rotation hexagonal boss 18 and die nut cooperate, antitheft at the top of the Anti-theft valve 01 Valve 01 passes through ring flange 11 and oil pipeline flanged joint.
