Abstract
The invention relates to a gas expansion type temperature controller that comprises a spring. One end of the spring is fixed on a box body and the other end of the spring is provided with a moving contact. A first contact and a second contact are fixed at two sides of the moving contact in the box body. A capillary tube is communicated with a temperature sensing tube and an expansion capsule. One surface of the expansion capsule is fixed on the box body and a fine tuning mechanism is arranged between the expansion capsule and the box body; and the other surface is crimped on the spring. When the temperature of the temperature sensing tube is changed, a gas medium in the temperature sensing tube generates a corresponded physical phenomenon of expansion caused by heat and contraction caused by cold; the expansion capsule that is communicated with the temperature sensing tube by the capillary tube generates expansion or contraction; the expansion capsule suppresses the spring; and according to the lever principle, the moving contact at the other end of the spring can be switchedly contacted with the first contact and the second contact, so that the on-off motion of a switch can be driven and thus an objective of constant temperature is achieved. According to the gas expansion type temperature controller provided in the invention, the working medium employs a gas medium; a working range is large; and a highest temperature can reach 700 DEG C; therefore, the controller has a wide application range.
Description
Technical field
The present invention relates to a kind of temperature controller, particularly a kind of gas expansion type temperature controller.
Background technology
Liquid expanding thermostat is widely used in the industries such as household electrical appliances, electroheat equipment, refrigeration plant, but traditional liquid expanding thermostat, its Applicable temperature scope can only-the 30-300 degree is interval, has limited the scope of using, and has adapted to not the social development demand.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the object of the present invention is to provide a kind of gas expansion type temperature controller, have the big advantage of temperature-measuring range.
For reaching above-mentioned purpose, technical scheme of the present invention is following:
A kind of expansion type temperature controller comprises shell fragment 5, and shell fragment 5 one ends are fixed on the box body 3; The other end is provided with moving contact 6; Box body 3 is fixed with first contact 7, second contact 8 on the both sides of moving contact 6, capillary 2 is communicated with temperature-sensitive pipes 1 and expansion bellows 4, and the one side of expansion bellows 4 is fixed on the box body 3; Be provided with micro-adjusting mechanism 9 between the two, another side is crimped on the shell fragment 5.
When the temperature at temperature-sensitive pipe of the present invention place changed, the interior gas medium of temperature-sensitive pipe produced the physical phenomenon of expanding with heat and contract with cold accordingly, expanded or contraction with the expansion bellows generation that the temperature-sensitive pipe is communicated with through capillary; The expansion bellows suppresses shell fragment, and through lever principle, the moving contact of the shell fragment other end can contact with first contact, the switching of second contact; Can drive the switch on and off action; Reach the constant temperature purpose, working media of the present invention has adopted gas medium, and the scope of its work is bigger; Maximum temperature can reach 700 degree, and the scope of application is big.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
Shown in accompanying drawing, a kind of gas expansion type temperature controller comprises shell fragment 5; Shell fragment 5 one ends are fixed on the box body 3, and shell fragment 5 other ends are provided with moving contact 6, and expansion bellows 4 is the enclosed constructions that are made up of two parallel corrugated platings; Box body 3 is fixed with first contact 7, second contact 8 on perpendicular to the corrugated plating direction on the both sides of moving contact 6, gassy medium in the temperature-sensitive pipe 1, and the gas medium in the temperature-sensitive pipe 1 can be nitrogen; Also can be other inert gas, capillary 2 is communicated with temperature-sensitive pipe 1 and expansion bellows 4, and the one side of expansion bellows 4 is fixed on the box body 3; Another side is crimped on the shell fragment 5, when expansion bellows 4 expands, with shell fragment 5 pressed downward; The moving contact of shell fragment 5 other ends can switch with first contact 7, second contact 8 and contacts; Bellows 4 is fixed between one side and the box body 3 on the box body 3 and is provided with micro-adjusting mechanism 9, and micro-adjusting mechanism 9 can be adjusted the position that expanded film box 4 is crimped on shell fragment 5, the scope of adjustment temperature control.
In the accompanying drawing: 1 is the temperature-sensitive pipe; 2 is capillary; 3 is box body; 4 are the expansion bellows; 5 is shell fragment; 6 is moving contact; 7 is first contact; 8 is second contact; 9 is micro-adjusting mechanism.
