Description
Technical field
The utility model belongs to the anti-theft device of valve, and particularly antitheft handwheel and handwheel guard shield and switching tools are applicable to that places such as producing well well head water mixing valve in the petroleum industry wild environment, individual well tank unloading valve use.Prevent that the lawless person from destroying equipment, stealing crude oil from valve, convenient daily production management work.
Background technology
Because the producing well of petroleum industry is in the field, the lawless person often takes to close well head water mixing gate or closes the production gate in order to steal crude oil, steals crude oil.Because water mixing closing gate overlong time, to find untimelyly, water mixing can not be mixed and is caused the pipeline back pressure to raise, and is easy to the plugging line.Though taked to reinforce handwheel or dismantle handwheel with sucker rod, make an iron cover, cover leading screw, be welded on method guard against theft oil on the gate with electric welding.But regulate watering quantity to oil well like this, bring inconvenience.When regulating watering quantity if desired, must sever cover, have very big potential safety hazard with gas welding.Not only cause crude oil loss and workload to increase, and influenced the normal operation of producing to a great extent.
Summary of the invention
The purpose of this utility model provides antitheft handwheel and handwheel guard shield and switching tools, and convenient daily production management prevents that the lawless person from stealing crude oil.
The purpose of this utility model is achieved in that
The contour structures of antitheft handwheel is a multiple edge body, and circle is provided with keyway in it, and the interior circle of antitheft handwheel cooperates with the handwheel installation end of valve leading screw, and the handwheel of original valve is dismantled, and this antitheft handwheel is loaded onto.
The handwheel guard shield comprises cover body and plug, and circle is provided with every platform in the cover body middle part, and circle is provided with screw thread in platform; The internal diameter of circle is greater than the external diameter of handwheel in the cover body welding ends, and plug circle in the cover body other end is packed into every platform.The welding ends of cover body is welded on the outer rim of valve bonnet flange.
Switching tools one end of antitheft handwheel and handwheel guard shield is the handwheel key, and the other end is the guard shield key; The interior round structure of handwheel key cooperates with the contour structures of handwheel; The interior round structure of guard shield key cooperates with the contour structures of plug installing handle.Use one switching tools, open the two-stage security settings, easy to operate.
The utlity model has following useful effect: the utility model is simple in structure, easy for installation.Antitheft handwheel and handwheel guard shield form the two-stage security settings for the stolen molecule, set up defenses in depth.Switching tools is manufactured exquisiteness, and is easy to carry, can finish operations such as Open valve flashboard.A switching tools can be opened the two-stage security settings, is daily adjusting well head watering quantity, and the unlatching work of individual well tank unloading valve and producing well well head water mixing valve provides convenience.The utility model can make full use of waste and old tubing and each parts is manufactured in pole stock processing, further reduces production costs.The utility model anti-theft effect is good, has reduced and has stopped the well time, retrieves because of stopping the crude oil loss that well causes, and has improved operating efficiency and economic benefit.
