Description
Technical field
It the utility model is related to the design field of long closing well Anti-theft device for wall head.
Background technology
Some low yield inefficient wells of directorial area generally existing, after closing well in the case that extraction value is little, some well heads by
From far-off regions in being located in comparison, the carelessness of oil recovery shift management is non-anti-theft without permanently envelope note, is subject to criminal's
Destroy, steal, cause crude oil excessive, polluted environment, trigger accident, cause irredeemable loss.
Utility model content
The utility model purpose is to be directed to problem above, there is provided a kind of simple in construction, easy for installation, simple operation, peace
Complete antitheft long closing well Anti-theft device for wall head.
The utility model includes screw mandrel, connects valve plate in the screw mandrel lower end, valve pocket is set on the outside of the valve plate, described
Valve plate, valve pocket may be contained within body cavity, and bonnet is set above the body cavity;Cut in screw mandrel outside screw connection
Face is the copper sheathing of polygon;It is that locking protective case is set on the outside of the copper sheathing of polygon in the section, the bonnet threaded connection
In the outside of locking protective case;Embedded pin is set to be used to be connected with locking protective case on the bonnet perisporium;The valve
Body both ends pass through clamp connection hoop respectively;Each described clip includes upper card body, lower card body, upper card body, lower card respectively
Pass through anti-theft bolt, nut check between body respectively;Guard ring is set respectively at the both ends of upper card body, the anti-theft bolt described in every
It is each passed through guard ring and lower end is threadedly coupled with lower card body, the nut of the anti-theft bolt is embedded in guard ring respectively is arranged.
The utility model has the advantages that:1)Original handwheel and key are eliminated, the copper sheathing of circle is changed to polygon copper sheathing,
Have to special box spanner could rotating switch gate, and a locking protective case is devised outside copper sheathing, so
Undesirable just can not open and destroy;2)A safety pin is devised on big gland, big gland and protective case are consolidated
It is scheduled on together, can not be arbitrarily dismantled;3)One guard ring in clip exterior design, makes nut be embedded in clip body, must
It must could be dismantled with special spanner, add anti-theft capability.The utility model is simple in construction, easy for installation, simple operation,
Safe antitheft.
The nut of anti-theft bolt described in the utility model is provided with quincunx screw, it is necessary to has special key and is torn open
Unload, strengthen antitheft.
