Abstract
The utility model relates to an electrical heating thermal-insulation device for wellhead equipment. The electrical heating thermal-insulation device comprises electric heating tapes and thermal-insulation fireproof quilts. The electric heating tapes are adhered to the outer surfaces of the inner layers of the thermal-insulation fireproof quilts. A plurality of heating wires of different powers are disposed in each electric heating tape and each heating fire is formed into an independent loop. The outer layer of each thermal-insulation fireproof quilt is an aluminum foil cloth layer, the middle layer a fireproof thermal-insulation glass fiber cotton layer and the inner layer a fireproof glass fiber clothe layer. The electrical heating thermal-insulation device comprises a plurality of the thermal-insulation fireproof quilts. Each thermal-insulation fireproof quilt is provided with an extensible concave-convex corrugated connecting member. Adjacent connecting members are movably connected with each other through connecting buckles. Convenience in connecting, flexible deformation and wrapping of the plurality of thermal-insulation quilts is realized. The electrical heating thermal-insulation device realizes full covering and wrapping of the wellhead equipment of different shapes, facilitates installing and dismounting, saves working hours and improves a thermal-insulation effect.
Description
Technical field
The utility model relates to a kind of wellhead equipment direct current heating and heat-insulating device, relates in particular to a kind of heating and heat-insulating device that wraps insulation quilt and heater block formation, is specially adapted to the heat tracing of irregular well head oil production equipments such as concaveconvex shape and branch shape.Belong to hot conduction technique field.
Background technology
At present, each drilling well, sidetracking, overhaul well construction scene be employed oil well rig heating and heat-insulating device in the winter time, all be that employing voltage is electric heating coil or the ribbon heater heat tracing of 220V, the attemperator operation especially in the open air of this ribbon heater exists water resistance and insulating properties poor, easily electric leakage is hurted sb.'s feelings, easily the shortcoming that the pry-effect is low and application life is short is beaten in short circuit, the cladding material of some ribbon heater is with metal or pottery simultaneously, thereby be difficult for on-the-spot bending, so be difficult for wrapping irregular oil well rigs such as concaveconvex shape and branch shape.Above-mentioned these defectives have become a big potential safety hazard of shaft mouth operation construction in winter.For this reason, we spy has developed a kind of " straight electric heating and thermal insulation device of oil well rig " that adapts to the requirement of oil well working environment in winter.
Summary of the invention
For solve existing well jaws equipment attemperator easily electric leakage hurt sb.'s feelings, short circuit beat pry-imitate low, be inconvenient to wrap the heat tracing problem, the utility model proposes a kind of wellhead equipment electrical heat tracing device.
To achieve these goals, the utility model takes following technical scheme to implement: it includes heat tape and insulated fire quilt, is affixed on insulated fire by inner layer outer surface in heat tape is sticking.
Described heat tape comprises heating wire, glass layer, layer of silica gel, and heating wire places among the glass layer, and glass fiber is placed among the layer of silica gel; Described different capacity heating wire is set to many, and every heating wire constitutes independent loop separately.
Insulated fire is involved skin, intermediate layer, internal layer, and described insulated fire is that aluminium foil layer of cloth, intermediate layer are that the cotton layer of fireproof heat insulating glass, internal layer are fire prevention glass layer of cloth by skin; Described insulated fire be polylith, every fire prevention by between telescopic connector is set, described connector is arranged to concavo-convex corrugation, makes between described connector and the described fire prevention quilt to be connected, and flexibly connects by junction button between the described adjacent connector.The utility model is convenient to connection between a plurality of insulation quilts, dilatation and parcel.Design of the present utility model makes different wellhead equipment realize that all standing wraps, and has made things convenient for dress and torn open.Save the working time, promoted heat insulation effect.
The utlity model has fire prevention, anticreep, anti-short circuit, thermal efficiency height, saves energy and advantages such as the raw material loss is few, easy to assemble, long service life.
Description of drawings
Accompanying drawing 1 is looked sectional view for the heat tape master,
Accompanying drawing 2 be in the accompanying drawing 1 A-A to diagram;
Accompanying drawing 3 be insulated fire by the external surface view,
Accompanying drawing 3 be in the accompanying drawing 3 B-B to diagram.
In the accompanying drawing, 1 is layer of silica gel, and 2 is glass layer, and 3 is heating wire, and 4 is power line, and 5 is junction button, and 6 are fire prevention glass layer of cloth, and 7 is the cotton layer of fireproof heat insulating glass, and 8 is the aluminium foil layer of cloth, and 9 is sewing line, and 10 is connector.
The specific embodiment
Shown in accompanying drawing 1,2, make the heat tape that the two-way electrical power does not wait, heating wire 3 is placed among the glass layer 2, the external surface at glass layer 2 arranges layer of silica gel 1 again.The laying as shown in Figure 1 of heating wire 3 in the above-mentioned manufacturing process constitutes two electric loops between power line 4 and the heating wire 3, select the loop of different capacity as required.Shown in accompanying drawing 3,4, be aluminium foil layer of cloth 8, middle be the order storing for the ecto-entad of the glass layer of cloth 6 of preventing fires of the cotton layer 7 of fireproof heat insulating glass, internal layer by skin, above-mentioned three layered suture systems are connected into the main body of insulated fire quilt, connector 10 is set around the main body of the insulated fire quilt of making as stated above again.Described connector 10 is designed to concavo-convex corrugation, has enough elasticity and flexible.When insulated fire was wrapped irregular wellhead equipment, the required stretching degree of each several part had nothing in common with each other, and the concavo-convex wrinkle part in the connector 10 gives necessary replenishing at this moment.A plurality of junction buttons 5 are set on the edge of described connector 10 can be connected the aforementioned insulated fire of polylith.When using on irregular wellhead equipments such as concaveconvex shape and branch shape, the utility model just can realize wrapping.The multichannel of heating wire 3 design in the utility model can be selected according to the demand of actual environment, saves energy not only, and use also can be continued in another road when a certain road heating wire damages, thus improved heating tape application life.
