Abstract
The utility model relates to a pressure controller, which is characterized in that shell is provided with a shell cover. One side of the shell is provided with a wire connecting hole, and the other side is provided with an external adjusting hole. Pressure joint is connected with a support plate which can support switch element. One end of the support plate is connected with a spring frame, and the other end of the spring frame is connected with an adjusting bolt. A microswitch is fixed on the spring frame. One end of spring tube is connected with the pressure joint, and the other end of the spring tube is connected with the microswitch. The utility model has the advantages that 1, the spring tube can directly and precisely push the microswitch with few transmission levels so to improve reliability and accuracy of control; 2, the utility model is characterized in high power control point, high reliability, simple structure and easy use, and can be used widely in test and control of industrial process.
Description
Technical field
The utility model belongs to instrument and meter, particularly a kind of pressure controller.
Background technology
In the industrial detection control procedure, often need manometer when a certain force value, provide a contact point signal, so that control, generally adopted electro connecting pressure gauge in the past, but because its structure is limit, and contactless power is less, poor reliability, the life-span is short.
Summary of the invention
The purpose of this utility model provides a kind of pressure controller, and it overcomes above-mentioned defective, has improved pressure controlled reliability and accuracy.
The technical solution of the utility model is: a kind of pressure controller, it is characterized in that: it is made up of watchcase, connection terminal, compression fittings, supporting plate, adjustment spring, spring suppport, microswitch, bourdon tube, the upper end of watchcase is provided with cap, watchcase one side is provided with wiring hole, opposite side is provided with the outer hole of adjusting, and the watchcase bottom is fixed with connection terminal, watchcase lower end setting pressure joint, in the compression fittings and the watchcase of packing into, be communicated with bourdon tube; Fixing supporting plate on the compression fittings is used for the supporting switch assembly; One end of supporting plate connects spring suppport, and the other end of spring suppport is fixed with the adjustment screw, adjusts screw and press-fits the adjustment spring; Fixing microswitch on the spring suppport; Compression fittings connects bourdon tube one end, and the other end of bourdon tube connects microswitch.
Between said watchcase and cap packoff is installed.
Said watchcase and outer the adjustment between the hole are installed packoff.
Between said watchcase and wiring hole packoff is installed.
The utlity model has following advantage: 1, adopt bourdon tube directly to promote microswitch, the mechanical drive level is inferior few, and the precision height has improved the reliability and the accuracy of control; 2, contactless power is big, reliability is high, simple in structure, easy to use, can be widely used in the industrial process detection control.
