Abstract
The utility model relates to a pressure style temperature controller with a fixed temperature alarm, which is mainly comprises a temperature regulating mechanism composed of a knob shaft and a cam, a body part composed of an adjustment lever, an auxiliary lever and an inverse L-shaped lever, a switch box part composed of a main switch group and an alarm signal output switch group, and a power part composed of a corrugated pipe and a temperature-sensing capillary pipe, wherein, the body part and the switch case part are connected through a plastic push rod. The utility model has the advantages of compact structure, stable performance, and accurate fixed temperature alarm, and is an ideal pressure style temperature controller with a fixed temperature alarm in refrigerant systems.
Description
The utility model relates to a kind of band constant temperature alarm type pressure type temperature controller, belongs to basic device, is widely used in control and regulates refrigerator, refrigerator, air conditioner and other refrigeration plant.
Existing electric temperature regulator type pressure type temperature controller is in any position no matter characteristics are rotation axiss, and during connection, the temperature that is reached all is consistent, but does not have warning function.Be mainly used in control plain edition cold compartment of refrigerator, its temperature characteristics as shown in Figure 1.Common band alarm type pressure type temperature controller, in control system, it is made up of two cover switches, as long as temperature reaches or is higher than the alarm temperature that sets, then alarm switch is just connected, output alarm signal, this type of temperature controller, be mainly used in the refrigerating chamber of control refrigerator and refrigerator, its temperature characteristics as shown in Figure 2.As can be seen from Figure 2, be characterized in when thermoregulative mechanism is in diverse location that the alarm temperature of the alerting signal of being exported is also different, for the part refrigeration system, does not reach needed warning requirement.Even the false alarm phenomenon can appear.So just limited the usable range of common band alarm type pressure type temperature controller widely.
The purpose of this utility model provides a kind of novel pressure and temp controller, remedies the deficiency of above-mentioned two kinds of pressure type temperature controllers, and has the temperature characterisitic and the function of above-mentioned two kinds of pressure type temperature controllers.Enlarge the range of application of band alarm type pressure type temperature controller, and though reach the temperature adjustment axle be in any position can both be under the constant temperature situation output alarm signal accurately.Its temperature characteristics as shown in Figure 3.
Structure of the present utility model, mainly by thermoregulative mechanism, body part, switch enclosure parts, power spare four parts are formed, and it is characterized in that the switch enclosure part be combined into of one-piece construction by the body part of electric temperature regulator type pressure type temperature controller and common band alarm type pressure type temperature controller; Switch enclosure partly is located at top, and body part is located at the bottom and is connected by a plastics push rod; Body part is made up of adjustment (adjusting) lever, auxiliary lever and shape lever.Adjustment (adjusting) lever is connected by spring, screw with auxiliary lever, and the branch screw that shakes is adorned in the auxiliary lever lower right, shape lever top dress plastics push rod; The switch enclosure parts are made up of main switch group and alerting signal output switches set, link to each other with the upper end of plastics push rod; Thermoregulative mechanism is made up of rotation axis and cam, is contained in the left side, joins with the upper end of adjustment (adjusting) lever; Power spare is made up of a corrugated tube and a temperature-sensitive kapillary, is contained in the right, joins with shape lever.Thermoregulative mechanism is by the difference of cam lift, the starting force difference of spring, and reach the temperature adjustment purpose.The size of the spring starting force on the adjustment (adjusting) lever of body part is subjected to the temperature adjustment mechanism controls, the starting force of the spring on the lever is in case just become definite value after setting up, and the spring on the auxiliary lever is because of linking to each other with adjustment (adjusting) lever, after if the branch screw that shakes above it is set up, when thermoregulative mechanism was in a certain position, the starting force of the spring on the auxiliary lever also just became certain value.The switch enclosure parts are made up of two independent switch groups (being main switch group and alerting signal output switches set), and when push rod moved upward, two switches set were connected respectively, and when moving downward, two switches set disconnect respectively.Power spare is made up of a corrugated tube and a temperature-sensitive kapillary, in fill temperature-sensitive working medium, according to principle of expanding with heat and contracting with cold, temperature raises, the corrugated tube internal pressure increases, corrugated tube will withstand shape lever to left movement, otherwise then move right, and promptly temperature raises, corrugated tube is to left movement, reach (setting) behind the certain value, by push rod main switch is connected, at this moment, auxiliary lever is eliminated the effect of shape lever by the set screw on it, temperature is elevated to certain value again, and shape lever continues to left movement under the situation that is not subjected to adjustment (adjusting) lever and auxiliary lever effect, the drive push rod moves upward, make alerting signal export switch connection, output alarm signal is realized warning function.In this process, alerting signal output switch is not subjected to the influence of thermoregulative mechanism, so realized the constant temperature warning at the utility model.
The utility model compact conformation, stable performance, constant temperature is reported to the police accurately, and range of application is wider, is comparatively ideal band constant temperature alarm type pressure type temperature controller in the refrigeration system.
