Abstract
The utility model relates to a temperature controlling element of liquid expansion and contraction, wherein, a shell is made of glass or other metal materials, and liquid is filled in the shell; a half piston is arranged on a round opening of the shell, or the round opening of the shell is sealed by a hose jacket, a piston is arranged on the hose jacket, and a sleeve is arranged outside the hose jacket. The utility model has the characteristics of simple structure, low cost, wide application, high precision in controlling temperature, large pressure, etc. The accuracy of the utility model can reach +/-0.1 DEG C, and the temperature control range of the utility model can change between-40 DEG C to 100 DEG C. The utility model is suitable for industry, agriculture and household appliances, such as room temperature controllers, air conditioners, fridges and various thermotanks to control temperature.
Description
The utility model be a kind of be the temp-controlling element of breathing body with liquid.The expansion coefficient of liquid is bigger approximately 100 times than solid, and can produce bigger action force and higher sensitivity.
The element that general using breathing pressure carries out temperature control has three kinds:
1. utilize the breathing cake of gas breathing pressure, mostly be used for the temperature control of hatcher and warmer, though the expansion coefficient of gas greater than liquid, is non-linear expansion, and flexible, can not produce bigger action force.
2. utilize the thermostat of the glass bar cover copper pipe of solid breathing pressure, be used for the temperature control of baking oven more, the expansion coefficient of solid is equivalent to 1/100 of liquid, so its sensitivity is relatively poor, but can produce bigger action force.
3. the bimetallic strip heated bending that utilizes two kinds of different sheet metals of expansion coefficient to make is controlled the thermostat of temperature, is applied to the temperature control of baking oven and electric iron etc. more, and sensitivity is relatively poor, and the action force that can produce is also very little.
In order to solve the shortcoming of above-mentioned three kinds of element deficiencies, be the temp-controlling element of breathing body and trial-produce successfully with liquid.
The utility model is achieved like this, when element is heated intensification, because liquid is greater than about 100 times of housing expansion coefficient, so the increase of vome of shell is less than the increase of liquid volume, cause liquid promotion piston or half piston protruding, back down the electrical contact that links to each other with piston or half piston and cut off circuit, therefore, temperature no longer raises.Temperature descends after cutting off circuit, contracts in piston or half piston thereupon, and electrical contact recloses circuit, and temperature rises again, and so circular flow can reach the purpose of temperature control.
The temperature control of liquid breathing temp-controlling element is not by resistance variations, but control on piston or half piston by the powerful thrust of expanded by heating generation, so also be applicable to the temperature regulating device of NOT-circuit, can be widely used in non-transformer district automatic shutter fire door control stove fire power, the flame height of kerosene hatcher, warmer, and the automatic shutter valve is regulated aspects such as heat extraction ventilation.
The utlity model has simple in structure, cheap, applied widely and temperature-controlled precision advantages of higher.The manufacturing of this temp-controlling element, not because of the material difference, shape size and with which kind of liquid specific (special) requirements to some extent, all can change according to the purposes requirement.The precision of this temp-controlling element can reach ± 0.1 ℃, the temperature control scope can-40 ℃～100 ℃ with interior variation, it is the ideal element of industry, agricultural, household electrical appliance and NOT-circuit facility temperature control.
The concrete structure of this temp-controlling element is provided by following embodiment and accompanying drawing.
Fig. 1 is half liquid breathing temp-controlling element in the form of piston.So-called half piston type is meant that the piston that is in operation can make it protruding when heated liquid expands, and temperature can not be return original position after descending.But when temperature edged down, piston but can inside delicately micro.And when temperature descends significantly, just can not reset significantly, so can only be used to be higher than the controller of room temperature.Fig. 1 temp-controlling element is made up of housing (1), the liquid (2) that is full of housing and half piston (3).Heated liquid when temperature raises in the housing expands, and promotes half piston (3) and moves outside direction shown in the arrow (4), backs down the electrical contact (not shown), cuts off circuit.After the circuitry cuts, temperature descends, the liquid shrinkage, and half piston (3) recloses electrical contact along contracting in the direction shown in the arrow (5), begins another working cycle.
Fig. 2 is the liquid breathing temp-controlling element that is with Hose Jacket, sleeve and piston is housed.It by housing (1), be full of housing liquid (2), seal the Hose Jacket (3) of housing round mouth, the sleeve (4) and the piston (5) that tightly are enclosed within on the housing round mouth constituted.When temperature raises, the liquid in the housing (2) expanded by heating, it is protruding to promote Hose Jacket (3), and piston (5) is moved along direction shown in the arrow (6), backs down the electrical contact (not shown), cuts off circuit.After the circuitry cuts, temperature descends, liquid (2) shrinkage, and piston (5) is shunk back along direction shown in the arrow (7) with Hose Jacket (3), and electrical contact is connected circuit again.The temp-controlling element of this structure, the piston mobile range is big, can be applicable to the temperature control of various thermostats above and below room temperature, air conditioner, refrigerator and various constant temperature ovens.
Claims (2)
1, a kind of temp-controlling element that utilizes liquid as expander is characterized in that liquid (2) expanded by heating in the housing (1), promotes half piston (3), and transmit fluid breathing pressure carries out temperature control.
2, temp-controlling element according to claim 1, it is characterized in that liquid (2) in the housing (1) is heated occurrence temperature when just changing, the also corresponding work height of liquid level changes, and the breathing pressure that makes Hose Jacket (3) promote piston (5) transmit fluid carries out temperature control.
