If do not adopt the rubber element of heating, the water of aircraft and uselessWater system pipe interface will freeze, and when serious, pipeline generation ice is stifled, affect water and the waste water system of aircraftThe operation of system.
Existing rubber heat pad by rubber seal, high temperature resistant wire draw, lectrothermal alloy wire forms,Rubber seal is the two-layer rubber blanket composition that is bonded together, and lectrothermal alloy wire is bonded in to two-layer rubberIn the middle of rubber cushion. The rubber of this kind of structure pad of heating, lectrothermal alloy wire and pipeline can not be isolated completely,Poor insulativity; Without temperature control, easily high temperature causes burning, exists reliability and service life lowProblem.
Summary of the invention
The object of the invention is to propose that a kind of good insulating, reliability are high, long service life can be fromThe moving temperature automatically controlled rubber-heating pad of temperature controlled one that carries out. Technical solution of the present inventionBe, temperature automatically controlled rubber-heating pad comprises rubber seal, high temperature resistant wire, lectrothermal alloy wire,It is characterized in that: electrical heating B alloy wire is coiled on rubber blank flat, and temperature controller is placed in rubber blank flatUpper, the two ends of temperature controller are connected with one end of two electrical heating B alloy wires, two electrical heating B alloy wiresOther two ends be connected with high temperature resistant wire, the temperature controller combining and electrical heating B alloy wire and rubberBlank flat sulfidization molding forms rubber seal, and high temperature resistant wire is drawn to rubber seal.
Described temperature controller and electrical heating B alloy wire are placed in the parcel completely of rubber seal.
Described lectrothermal alloy wire is shaped as linear state or turns to spiral status that to be placed in rubber closeIn sealing.
The advantage that the present invention has and beneficial effect, the present invention adopts sulfurization technology by electrical heating alloySilk and temperature controller are wrapped in rubber inside, good insulating completely; There is automatic temperature-adjusting control ability,Adopt temperature controller experience variations in temperature and heater circuit is controlled, it is the easiest that temperature controller is placed inExperience the place of pipeline temperature, in the time that temperature reduces, heater circuit is connected in temperature controller work, startsBy system heating, in the time that temperature raises, temperature controller work connects disconnection heater circuit, stops systemHeating. The present invention has advantages of reliability and high life, good insulating, ensures heating cushionIn the time of long-time hot operation, do not burn, can reach 30 years or 30000 service life and flyRow hour.

Fig. 2 is the temperature automatically controlled rubber-heating mat structure of the present invention's heater strip that linear state is installedFigure, wherein A figure is front view, B figure is vertical view cutaway drawing.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is elaborated. Temperature automatically controlled rubber-heating pad comprises: rubberGlue seal 1, high temperature resistant wire 2, lectrothermal alloy wire 3, temperature controller 4.
Set the break-make temperature spot of temperature controller, temperature is connected during lower than T1, and temperature disconnects higher than T2,The break-make temperature difference should be at 5 DEG C～25 DEG C.
By the length that specifies under lectrothermal alloy wire that resistance value requires, as required by electrothermal alloy filament windingMake spiral status Fig. 1 or alignment and become raw silk rings state diagram 2, electrical heating B alloy wire is coiled in to rubberIn blank flat, temperature controller is installed, and by temperature controller two ends and the crimping of electrical heating B alloy wire or welding,Other two ends and the high temperature resistant wire of electrical heating B alloy wire carry out crimping or welding; By the group combiningClose blank and be placed on curing forming mold, carry out moulding according to sulfuration process. After moulding, add heat sealSpun gold and temperature controller are placed in the parcel completely of rubber seal, lectrothermal alloy wire and temperature controller and pipeRoad isolates completely. Lectrothermal alloy wire is shaped as linear state or turns to spiral status, heater circuitDrawn by two high temperature resistant wires.
The present invention adopts sulfuration that electrical heating B alloy wire and temperature controller are wrapped in to rubber inside completely, andBe in the centre of rubber; Adopt temperature controller to experience variations in temperature and heater circuit is controlled to temperatureControl device is placed in the place of the most easily experiencing pipeline variations in temperature, in the time that temperature is reduced to T1, and temperatureHeater circuit is connected in the work of control device, starts system heating, and in the time that temperature raises higher than T2, temperatureThe work of control device connects disconnection heater circuit, stops system heating.
While installing and using on aircraft, temperature automatically controlled rubber-heating pad profile according to the water of aircraft andThe shape of the interface of waste water system designs, and rubber-heating pad is fitted in to interface needs closelyOn the face of heating, temperature controller is pressed close to the place of the most easily experiencing pipeline temperature most. This series products is flyingIn row device flight course, logical 115V, 400Hz alternating current, alternating current is through high temperature resistant wire power supplyHeat seal spun gold uses, and the heat that lectrothermal alloy wire produces is fed water by rubber seal transmission and waste water isThe interface of system, raises the temperature of interface, and when temperature is during higher than T1, temperature controller work disconnectsHeater circuit, stops heating, and when temperature is during lower than T2 DEG C, heater circuit is connected in temperature controller work,Start system heating.
The feature of rubber seal 1, function, its material is high-temperature-resisting silicon rubber, sealing temperature controlDevice and lectrothermal alloy wire, make temperature controller and lectrothermal alloy wire and line isolation; Lectrothermal alloy wire is producedRaw heat is passed interface.
The function of high temperature resistant wire 2, by 115V, 400Hz alternating current access lectrothermal alloy wire.
Lectrothermal alloy wire 3 has a feature, function, and its material is iron cobalt nickel alloy, be used for byElectric energy transfers heat energy to.
Temperature controller 4 has three features, function, is the bi-metal temperature gauge tap of miniaturization, profitWith the different heat expansion coefficient of two kinds of different metals, make it that on-off action occur. Experience pipeline temperatureChange, when temperature is during higher than T1 DEG C, temperature controller work disconnects heater circuit, when temperature is lower than T2 DEG CTime, heater circuit is connected in temperature controller work.
