Abstract
The utility model provides a built-in lock type anti-theft gate valve which mainly solves the problems that the cost of the anti-theft gate valve of the existing oil well is high, and the installation is inconvenient. The utility model is characterized in that the exterior of a nut (1) is connected with an anti-theft cover (2) whose lateral wall is provided with a hole through screw thread; hole of the lateral wall of the anti-theft cover (2) is fixed with an anti-theft lock (4) which is provided with a bolt (3); the upper end surface of a supporter (5) is provided with a groove (6) which corresponds to the bolt (3). The built-in lock type anti-theft gate valve has the advantages that the using performance of the original gate is not broken, the cost is low, and the structure is simple.
Description
Technical field:
The utility model relates to oil recovery field, oil field used well head gate, especially hidden-locked theft-proof gate valve.
Background technique:
Be connected with several gates on the on-the-spot at present profit production wellhead that uses, their main effect is the output of control crude oil and the injection of water.Do not having under the effective anti-theft measure situation, causing the frequent stolen oil molecule of gate to be opened, causing substantial oil stolen, crude oil is stolen not only to cause the tremendous economic loss to the oil field, and brings many inconvenience for daily production management, also is unfavorable for safety in production.And at present for delinquency prevention molecule stolen, production unit is dead with the flashboard weldering of gate, though the method can prevent stolen, but destroyed the due usability of gate, can't emptying when oil well needs emergency blow-down, if gate damages, can't keep in repair once more, original gate has been lost should have the value of use to cause material unaccounted-for (MUF) virtually.Adopt devices such as well head theft-proof box, well head Theft-proof collar clamp again, these facilities or high or because of inconvenience is installed, large-area applications gets up to be subjected to very big placing restrictions on because of cost can't satisfy needs antitheft in all oil well production fully.
The model utility content:
High and the deficiency of inconvenience is installed in order to overcome existing oil well Anti-theft anchor gate cost, the utility model provides a kind of hidden-locked theft-proof gate valve, and this hidden-locked theft-proof gate valve has and do not destroy the due usability of original gate, with low cost and characteristic of simple structure.
The technical solution of the utility model is: this hidden-locked theft-proof gate valve comprises nut and support, the outer upper end of nut links to each other with handwheel by key, there is screw thread the outer upper end of nut, the outer antitheft cover that is connected with holes at lateral wall by screw thread of nut, antitheft cover areole internal fixation has the burglarproof lock of tongue with lock, has on the support upper-end surface and the dead bolt corresponding groove.
The beneficial effect that the utlity model has is: this hidden-locked theft-proof gate valve is owing to be connected with antitheft cover at nut, burglarproof lock by antitheft cover one side is locked again, so just prevent stolen molecule starting gate effectively, when needs switch gate, there is key to open burglarproof lock, its antitheft cover is taken off, connect handwheel and get final product starting gate, realized switch to gate, also realized the purpose of delinquency prevention molecule stolen, and do not destroyed the due usability of original gate, with low cost and simple in structure, simultaneously easy for installation.
Description of drawings:
Accompanying drawing 1 is the utility model partial structurtes sectional views.
1-nut among the figure, the antitheft cover of 2-, 3-dead bolt, 4-burglarproof lock, 5-support, 6-groove.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this hidden-locked theft-proof gate valve comprises nut 1 and support 5, and nut 1 outer upper end links to each other with handwheel by key, and there is screw thread nut 1 outer upper end, drives nut by the handwheel rotation and rotates, and makes screw mandrel drive flashboard and moves up and down, and reaches the purpose of starting gate; Be connected with antitheft cover 2 by screw thread outside the nut 1, antitheft cover 2 links to each other and nut 1 upper end by the upper end internal thread, because of the open and close of gate are that the rotation of armrest wheel drives nut 1 and realizes moving up and down of screw mandrel, so by antitheft cover 2 nut 1 is covered, just reaches and prevent that the stolen molecule from preventing the purpose of rotating nut 1 starting gate; Antitheft cover 2 areole internal fixation have the burglarproof lock 4 of tongue 3 with lock, have on support 5 upper-end surfaces and dead bolt 3 corresponding groove 6, when the lower plane of antitheft cover 2 near or be closely attached on the support behind the plane, insert in the groove 6 of support 5 by the dead bolt 3 of key burglarproof lock 4, antitheft cover 2 promptly can't be rotated to break away from nut 1 and with nut 1 complete closed, thereby guaranteeing that gate is in can't open or closed condition, realized the purpose of delinquency prevention molecule stolen, and do not destroyed the due usability of original gate, with low cost and simple in structure, simultaneously easy for installation.
During actual the use, after common gate valve installs at the scene and comes into operation, can earlier handwheel be taken off, to be threaded onto with antitheft cover 2 internal threads of burglarproof lock 4 on the nut 1 of gate then, the following Transverse plane that makes antitheft cover 2 near or be closely attached on the last Transverse plane of support 5 and burglarproof lock 4 dead bolts 3 locks advanced in the groove 6 of support with key, it is interior and can not rotate to be housed in antitheft cover 2 fully with regard to the nut that makes gate like this.
