Description
Technical field
The utility model relates to thermostat technical field, and especially one has extra long life compression-type temperature controller, is applicable in refrigerator for controlling the compression-type temperature controller of refrigerant compressor break-make.
Background technology
Compression-type temperature controller is widely used in refrigerator refrigeration control.Existing compression-type temperature controller, primarily of shell, cover plate, camshaft, cam bit, Clip Reed, L shape master arm, extension spring, adjustment plate, push rod, touch spring, spring leaf, pin C, pin L, moving contact, fixed contact and bellows composition.Camshaft and cam bit by Clip Reed clamping on the cover board, become an entirety.One end of adjustment plate leans against in cam bit outer rim, and one end of extension spring is hung in the middle of adjustment plate by adjustment screw, and the other end hangs on L shape master arm; By adjusting the direction of camshaft, the position of adjustment plate can be changed, thus adjustment extension spring is to the pulling force of L shape master arm; Be provided with a through hole in dividing plate middle and upper part, push rod is through this through hole, and its two ends are connected with spring leaf, L shape master arm respectively; L shape master arm, under the acting in conjunction of bellows and extension spring, carries out reciprocating rotation, thus promotes push rod and carry out shift reciprocately; When falling at temperature, push rod moves to right, and when reaching critical break-off signal, push rod promotes spring leaf and produces kick, drives moving contact, fixed contact to throw off, circuit is disconnected, and temperature starts to rise; When temperature rises, push rod moves to left, and when reaching critical connection temperature, push rod drives spring leaf to produce kick, moving contact, fixed contact is bonded, makes circuit ON, and temperature starts to decline.Completed the control of temperature by the reciprocating friction of the salient point under L shape master arm and bellows, but existing bellows is easily damaged in long friction process, useful life is short.
Utility model content
The technical problems to be solved in the utility model is: be easily damaged in long friction process to solve existing bellows, the problem that useful life is short, the utility model provides a kind of extra long life compression-type temperature controller, by adding a wear-resistant gasket at the end face of bellows, effectively alleviate the friction between the salient point under bellows and L shape master arm, extend the useful life of thermostat, save use cost.
The utility model solves the technical scheme that its technical problem adopts: a kind of extra long life compression-type temperature controller, comprise shell, cover plate, camshaft, cam bit, Clip Reed, L shape master arm, extension spring, adjustment plate, push rod, touch spring, spring leaf, pin C, pin L, moving contact and fixed contact, also comprise bellows, described L shape master arm bottom is provided with a salient point, described salient point contacts with bellows and connects, and the end face that described bellows contacts with salient point is provided with the pad preventing bellows end face from wearing and tearing.
In order to reduce the friction between the salient point under bellows and L shape master arm, described pad is plastic spacer, and described plastic spacer is teflon gasket, polyformaldehyde pad or nylon spacer.Plastic spacer can be pasted onto on bellows end face by seccotine etc.
In order to alleviate the friction between the salient point under bellows and L shape master arm, described pad is metallic gasket, and described metallic gasket is potassium steel pad or stainless steel gasket.
The beneficial effects of the utility model are: a kind of extra long life compression-type temperature controller that the utility model provides, by adding a wear-resistant gasket at the end face of bellows, effectively alleviate the friction between the salient point under bellows and L shape master arm, extend the useful life of thermostat, save use cost; By selecting plastic spacer, the friction between the salient point under bellows and L shape master arm can be effectively reduced; By selecting metallic gasket, the friction between the salient point under line pipe and L shape master arm effectively can be alleviated.
