Abstract
The utility model relates to a measuring indicator, particularly a pressure and temperature indicator which is the improvement and the combination of a pressure indicator and a temperature indicator, and can simultaneously reflect the pressure and the temperature. The utility model is formed by the combination of a spring tube type pressure indicator and a spiral bimetallic-sheet type temperature indicator which are arranged on an indicator disk at the front of an indictor shell and are provided with a pressure displaying scale and a temperature displaying scale. A gear shaft which is used for installing a pressure indicating needle is provided with a center through hole, and a thin shaft which is used for installing a temperature indicating needle is penetrated and arranged in the center through hole. The utility model integrates the pressure measuring and the temperature measuring functions to a body, and can simultaneously reflect the pressure value and the temperature value of a measured medium. A temperature connector and the indicator shell adopt the steering corrugated tube connection, and the position and the orientation of an indicator head can be conveniently adjusted. The utility model has the advantages of flexible installation and use and convenient use.
Description
The utility model relates to the measurement indicating instrument, is a kind of indicated pressure simultaneously that tensimeter and thermometer are improved and combine and the meter of temperature.
The existing pressure measuring instrument that generally adopts is generally the pressure measuring instrument of spring-tube type, its structure is will be inserted the semi-circular bourdon tube that is installed in the watchcase by measuring pressure by compression fittings, make the sector gear that is connected its movable end drive the gear shaft that pointer is installed by pressure to the effect of bourdon tube and rotate, through with dial scale cooperate to come indicated pressure numerical value.And the existing temperature survey table that generally adopts is generally the temperature survey table of spiral bi-metal chip, its structure is the lower end that is configured in the temperature joint with the spiral bi-metal sheet as temperature-sensing element, when temperature variation, rely on reversing of spiral bi-metal sheet, the thin axle that pointer drive to be installed rotates, by with dial plate on scale cooperate to come indicated temperature numerical value.Above-mentioned pressure and temperature meter is the single pressure or the measurement instrument of temperature, when need reflect pressure and temperature simultaneously, then two measurement instruments must be installed respectively, brings many inconvenience for configuration and use.
It is one and provide a kind of with pressure and temperature measurement function collection at the problems referred to above that the purpose of this utility model is, thus convenient pressure, the temperature indicating gauge that disposes and use and satisfy pressure and temperature while display requirement.
The technical scheme that realizes above-mentioned purpose is: a kind of pressure, temperature indicating gauge, form by spring-tube type pressure measuring instrument and spiral bi-metal chip temperature survey table pack, its dial plate that is installed in the watchcase front is provided with the pressure demonstration and temperature shows two kinds of scales, wherein the gear shaft of setting pressure pointer is provided with central through hole, and the thin axle that the temperature pointer is installed is installed in its central through hole.
The technical solution of the utility model also comprises: compression fittings is stretched in the watchcase and by fixed pedestal and bourdon tube by the side direction of watchcase and joins; The temperature joint of its lower end configuration spiral bi-metal sheet temperature-sensing element is connected the back of watchcase by turning to corrugated tube.
The utlity model has the characteristics that on a meter, reflect institute's measuring pressure and temperature value simultaneously, and gauge outfit can be rotated adjustment surface location and direction, its installation and easy to use, flexible by corrugated tube.
The drawing of accompanying drawing is described as follows:
Fig. 1 is this pressure, temperature indicating gauge one-piece construction front view;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the front view of this pressure of reflection, temperature indicating gauge inner structure.
The utility model is described in further detail below in conjunction with drawings and Examples:
Provide as accompanying drawing, this pressure, temperature indicating gauge are that spring-tube type pressure measuring instrument and the improvement of spiral bi-metal chip temperature survey table are combined, its watchcase 1 is made up of columnar inside and outside shell phase retaining ring, the front portion of watchcase 1 is provided with transparent card 7 and dial plate 2, and its dial plate 2 is provided with the demonstration of inner ring pressure and the outer ring temperature shows two kinds of scales.Compression fittings 6 is stretched in the watchcase and by fixed pedestal 15 by the side direction of watchcase and is communicated with semiorbicular bourdon tube 8, and its pedestal 15 is provided with a support 19, is respectively fitted with gear shaft 14 that hairspring 16 is set and with the sector gear 17 of its engagement on this support.Pressure pointer 4 is installed in the front end of gear shaft 14.The free hinge ending connection of bourdon tube 8 is connected on an end of sector gear 17.After measured medium pressure or negative pressure are introduced into bourdon tube 8 by compression fittings, the bourdon tube free end is subjected to displacement, driving sector gear is that rotate at the center with its assembled shaft 18, and rotates through drive pressure pointer 4 with its meshed gears axle, indicates corresponding force value on index dial.Its gear shaft 14 is provided with central through hole, the thin axle 9 that front end is installed temperature pointer 3 is installed in its central through hole, the end of thin axle 9 extend out to outside the watchcase, and be connected the upper end of spiral bi-metal sheet temperature-sensing element 13 by spring 11, drive link 12, the other end of temperature-sensing element 13 is weldingly fixed in the stainless steel sleeve pipe, this sleeve pipe fixed configurations is in the lower end of temperature joint 5, and the upper end of its temperature joint 5 is connected the back of watchcase 1 by turning to corrugated tube 10.When the temperature joint was connected to measured medium, along with variation of temperature, the spirality bimetallic strip reversed, and drove thin axle 9 by drive link 12 and spring 11 and rotated, and temperature pointer 3 is rotated, thereby indicate temperature value intuitively by scale on dial plate.Compression fittings of the present utility model and temperature joint are inserted measured medium simultaneously, can reflect the pressure and temperature value of measured medium simultaneously.
