Background technique
Due to being changed by fuel oil temperature, the shell length of adjuster changes hydraulic mechanical type fuel regulator, influences to fire
The variation of oil conditioner internal control component controls rule, in order to compensate for the variation of the control law due to caused by temperature, generally
Temperature compensation means is set.Temperature sensor inside temperature compensation means experiences fuel oil temperature variation, and output displacement acts on
On control unit, so that control law meets the demand for control of engine.
Fuel regulator is in performance adjustment, since each product is influenced to cause to need temperature compensation means by temperature change
The difference of characteristic, this demand then need the temperature sensor of different size to meet design requirement.And traditional temperature-compensating
Device relies solely on temperature sensor characteristic, and for specific temperature sensor, being displaced output characteristics is determining, Wu Fajin
Row adjustment, therefore use scope is single, application is limited.
Summary of the invention
That the object of the present invention is to provide a kind of structures is simple, application range is big it is adjustable it is adjustable away from control with changed scale temperature
The control with changed scale temperature compensation means of compensation device pitch.
In addition, the present invention also provides it is a kind of it is adjustable away from control with changed scale temperature-compensation method.
The technical scheme is that it is a kind of it is adjustable away from control with changed scale temperature compensation means comprising shell, temperature pass
Sensor, slope eccentric cover, lever combination, displacement output end, wherein the temperature sensor and lever combination be encapsulated in shell and
In space composed by slope eccentric cover, and temperature sensor one end be arranged on slope eccentric cover, and in slope eccentric cover
Mandrel has a certain distance, the reception end in contact of the lever combination of the temperature sensor other end and adjustable angle, lever combination
Output end exports end in contact with the displacement for passing through shell, and the slope eccentric cover is rotatably adjusted with respect to shell.
The lever combination is made of receiving end, output end, supporting mechanism, zero point regulating mechanism, wherein receiving end and defeated
Outlet is hinged by supporting mechanism, and the adjusting of angle between the two is realized by zero point regulating mechanism, to change displacement output
Pitch.
The zero point regulating mechanism is zero point screw or zero point bolt.
Temperature sensor output displacement direction is identical as lever combination output displacement direction.
It is provided with oil liquid import and oil liquid outlet on shell, oil liquid is enabled to flow through temperature sensor.
It is a kind of based on it is described it is adjustable away from control with changed scale temperature compensation means temperature-compensation method, pass through rotation slope
Eccentric cover changes position of the temperature sensor in lever combination, to change the rate mu-factor k of input/output terminal, then leads to
The angular adjustment of lever combination is crossed, pitch b, the final simple function relationship for realizing input parameter x and output parameter y: y=are changed
Kx+b, wherein input parameter x is that temperature sensor experiences itself change in displacement caused by temperature change, and output parameter y is position
The displacement of shifter output terminal.
The solution have the advantages that: the present invention it is adjustable away from the output of control with changed scale temperature compensation means displacement and temperature
The proportional variation of the output displacement of sensor, and the adjustable change of ratio, while the initial bit of temperature compensation means output end
Setting can change.In addition the direction of displacement of temperature compensation means output and the output displacement direction of temperature sensor are in the same direction, structure
It is compact simple.The present invention it is adjustable away from control with changed scale temperature compensation means can reduce characteristic, precision, kind to temperature sensor
The requirement of class, specification can be adjusted the characteristic of temperature sensor by this device, and magnification ratio or diminution ratio carry out
Output effectively improves product using adaptability, expands application range, improve product economy.
Detailed description of the invention
Fig. 1 be the present invention it is adjustable away from control with changed scale temperature compensation means structural schematic diagram,
Wherein, 1- temperature sensor, 2- slope eccentric cover, 3- zero point regulating mechanism, 4- are displaced output end, 5- lever group
It closes, 6- shell.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Referring to Fig. 1, its be the present invention it is adjustable away from control with changed scale temperature compensation means structural schematic diagram.The present invention can
Adjust away from control with changed scale temperature compensation means include shell, temperature sensor, slope eccentric cover, lever combination, displacement output end.
Wherein, the temperature sensor and lever combination are encapsulated in space composed by shell and slope eccentric cover, and temperature sensing
Device one end, which is connected through a screw thread, to be fixed on slope eccentric cover, and has certain distance with slope eccentric cover central axis, is realized inclined
Heart design.The temperature sensor other end is output end, contacts with lever combination, carries out the transmitting of output displacement.
The lever combination is made of receiving end, output end, supporting mechanism, zero point regulating mechanism, wherein receiving end and temperature
Sensor output connection is spent, lever combination output end then exports end in contact with the displacement for passing through shell, and lever combination receives
