The scene of creeping into, oil field comprises kill manifold, well control manifold, and these manifolds relate to many valves, and Fig. 1 provides the structural representation of these valves, the discontinuous use of wellhead manifold in drilling process.In the winter of cold, when not using wellhead manifold, the residual liquid in these valves can produce and freeze phenomenon, causes to reuse the wellhead manifold difficulty, causes drilling well well pressure-controlled thrashing when serious, may cause serious accidents such as blowout.
Three, summary of the invention:
The purpose of this utility model provides a kind of oil drilling wellhead manifold valve heating and heat-insulating device, but this oil drilling wellhead manifold valve heating and heat-insulating device is used for solving drilling well wellhead manifold valve when drilling process be interrupted to use in the winter time, produces the problem of freezing.
The technical scheme that its technical problem that solves the utility model adopts is: this oil drilling wellhead manifold valve heating and heat-insulating device is dismountable, be fixed together by the fastening bolt make-up and form by at least two heating monomers, it is identical that each heats the be fixed together profile of the valve on shape and the manifold of the cavity that the back forms of monomer, valve can be fastened on wherein; Described heating monomer is a housing, and inner walls has insulation layer, and electric heater buckles into housing, is fastenedly connected with housing; Described electric heater installs insulation layer additional by outer casing inner wall, electrical heating elements is installed in the shell is constituted.
The heating monomer of such scheme is two.
The electric heater of such scheme is installed on the heating monomer corresponding to the spool place that is fastened on valve wherein.
Electrical heating elements in the such scheme is an electrical heating wire.
Beneficial effect:
1, the utility model is connected and fixed by dismountable heating monomer and forms, easy accessibility, drilling well wellhead manifold valve is interrupted when using winter, the utility model is fastened outside the valve that is installed on the manifold, can be to the valve heat tracing, guarantee that valve is interrupted when using winter, can not freeze, effectively prevent serious accidents such as blowout.
2, the electric heater in the utility model buckles into the heating monomer, the two is split, electric heater can disassemble from the heating monomer, when the electrical heating elements in the electric heater damages, electric heater is disassembled, replace with new electrical heating elements, again electric heater is installed to heat tracing once more on the heating monomer, cause short problem of the utility model life-span with regard to having avoided because of the electrical heating wire life-span is short like this, prolonged application life of the present utility model.
Four, description of drawings:
The structural representation of Fig. 1 drilling well wellhead manifold valve;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a lateral view of the present utility model;
Fig. 4 is a vertical view of the present utility model.
