Abstract
The utility model provides a bourdon tube pressure gauge. The pressure gauge mainly comprises a bourdon tube, a transmission mechanism, a sector gear, a pinion gear, a central shaft, an indicator, a dial and a gauge shell, wherein a cylindrical body with internal threads is arranged at the tail end of the sector gear; the transmission mechanism includes a snap spring pull rod and a measuring range adjusting screw rod; external threads are formed at one end of the measuring range adjusting screw rod and matched with the internal threads of the cylindrical body; the other end of the measuring range adjusting screw rod is threadless and is provided with a ring groove; a snap ring is arranged at one end of the snap spring pull rod and movably clamped in the ring groove of the measuring range adjusting screw rod; and the other end of the snap spring pull rod is connected with a free end of the bourdon tube. During measuring range verification, instead of opening the gauge shell, a user can extend a screw driver into the bourdon tube pressure gauge through a corresponding adjusting hole on the gauge shell, so as to realize the measuring range adjustment through the rotation of the measuring range adjusting screw rod. The operation is simple, rapid and convenient, so as to improve the verification efficiency of the bourdon tube pressure gauge.
Description
Technical field
The utility model belongs to the technology of instrument and meter field, relates to a kind of bourdon gauges, and relating in particular to is not a kind ofly needing to unload pointer and scaleplate, can directly carry out the bourdon gauges of range check.
Background technology
Bourdon gauges is used very extensive in fields such as chemical industry, thermal technologies.At present, generally the bourdon gauges of Shi Yonging mainly is made up of members such as spring tube bending, pull bar, sector gear, pinion wheel, central shaft, pointer, dial plates.It is oblate or oval that pipe section is, and its end is fixed on the supporting seat, and communicates with the carbonated drink medium; The other end is the free end of sealing, is connected with pull bar.The other end of lever connects sector gear, and sector gear is meshed with pinion wheel on the central shaft again, and manometric pointer is fixed on the central shaft.When spring tube bending is subjected to time spent of doing of pressure medium, its cross section has and becomes circular trend, forces spring tube bending to stretch gradually, thereby the free end of spring tube bending is upturned.Pressure is high more, and the amplitude that free end is upturned is big more.This move makes angle of needle deflection through the transmission of pull bar, sector gear, pinion wheel, indicates the pressure height on index dial.When measured medium pressure reduced, bourdon tube will restore to the original state, and pointer returns to corresponding scale place.
Tensimeter need carry out verification to zero point and range after using a stage.The bourdon gauges that generally uses is when verification tensimeter range at present, watchcase need be opened, unscrew the clamp nut (range adjustment nut) of pull bar and sector gear junction, then tie point is moved to the corresponding full scale position of estimating, tightening screw, load onto the scaleplate face, is under zero the situation feeding pressure, pointer is loaded onto, made it be designated as zero.Whether be forced into the range upper limit then, observe pointer and also be meant on upper limit scale, if just in time refer in the upper limit, then verification finishes.If refer on upper limit scale, then pressure leakage be fallen, pull down pointer and scaleplate then, the repetition said process is till zero point and range meet the demands.Therefore checking procedure is cumbersome, makes troubles to use.
Summary of the invention
The purpose of this utility model provides and is not a kind ofly needing to unload under the prerequisite of pointer and scaleplate, can directly carry out the bourdon gauges of range check.
Bourdon gauges of the present utility model, main member comprise bourdon tube, gear train, sector gear, pinion wheel, central shaft, pointer, dial plate and watchcase.
The tail end of described sector gear is provided with tapped right cylinder.Described gear train comprises range adjusting screw(rod) and jump ring pull bar.The external thread of one end of described range adjusting screw(rod) for matching with described cylindrical internal thread, the other end is a polished rod, and is provided with ring groove on polished rod.One end of described jump ring pull bar is a jump ring, and is installed in the ring groove of described range adjusting screw(rod), and movable in ring groove (comprise and rotating and twisting); The other end of jump ring pull bar is connected with the free end of described bourdon tube;
The head of described range adjusting screw(rod) is provided with cross or yi word pattern screwdriver groove, so that use the screwdriver rotary screw.The position of the corresponding range adjusting screw(rod) of described watchcase head is provided with adjustment hole, and corresponding plug is set on the adjustment hole.
The tapped right cylinder of described sector gear tail end is provided with fixedly jackscrew, so that after verification finishes sector gear and range adjusting screw(rod) are fixed together.The corresponding fixedly position of jackscrew of described watchcase has aperture, and corresponding plug is set.
Principle of the present utility model: by rotating the range adjusting screw(rod) to adjust the distance between jump ring pull bar and sector gear rotating shaft, to realize the verification of tensimeter range.
The utility model is with respect to the advantage of prior art: when carrying out the bourdon gauges range check, needn't open watchcase, but stretch into from the corresponding adjustment hole of watchcase with screwdriver, by rotating the range adjusting screw(rod) to realize the adjustment of range, it is simple to operate, efficient and convenient, improved manometric verification efficient.
