Abstract
The utility model provides an improved bourdon tube pressure gauge, that is a super-pressure resistant bourdon tube pressure gauge which mainly comprises a joint 1, a dial disc 2, a pointer 3, a machine base 4, an upper splint 6, a hair spring 7, a lower plate 8, a central gear 9 and a sector gear 10, wherein, a pole 15 is fixed on the lower plate 8. Added with the function of super-pressure resistant, the super-pressure resistant bourdon tube pressure gauge can bear violent and frequent pressure and super-pressure without affecting measurement accuracy, damage phenomenon caused by super-pressure is avoided, maintenance and examination workload are reduced, service life is prolonged, and manufacture is easy.
Description
The utility model is the improvement to former bourdon gauges.
Common bourdon gauges obtains using extremely widely in industrial enterprise, but this tensimeter fluctuates in by pressure measurement when violent or frequent, especially when instantaneous above tested manometric range by measuring pressure, the gauge hand up time forwards to keeps off on the head zero point on tensimeter surface, since gauge hand is the axle with central gear be close to cooperate fixing, pointer has just changed original fixed position under the superpressure situation like this, the pressure of superpressure backpointer indication just is not pressure accurately, every superpressure once will be pulled down calibrating again once.Not only influenced the use of this equipment, and frequent fragile pressure tapping of demolition, installation tensimeter and manometric inner body, manometric serviceable life reduced.
The purpose of this utility model has provided a kind of improved bourdon gauges, increases the anti-overpressure function of former spring manometer.
The utility model is achieved in that it mainly is to have increased a post, is fixed on the appropriate location of lower plate.
Adopt the novel spring hook gauge of above-mentioned measure, when instantaneous pressure surpasses range, when sector gear deflects into a certain position counterclockwise, just no longer continue counterclockwise deflection, pointer some fixed positions deflection no longer clockwise of arriving like this, also, no longer change the position of pointer and sun gear shaft, can not produce the change of superpressure backpointer null position with regard to bumping less than keeping off head the zero point on the panel.It has following advantage.
(1) can bear violent and frequent pressure surge and superpressure, and not influence its measuring accuracy.
(2) under violent and frequent pressure surge and superpressure service condition, significantly reduced maintenance and calibration operation amount, prolong serviceable life simultaneously and kept precision.
(3) cost is low, making is easy.
Below in conjunction with drawings and Examples concrete structure of the present utility model is described.
Fig. 1 is the synoptic diagram of the utility model structure.Fig. 2 is the synoptic diagram of one partial interior structure.
As shown in drawings, the utility model mainly comprises joint 1, index dial 2, pointer 3, support 4, bourdon tube 5, train wheel bridge 6, hairspring 7, lower plate 8, central gear 9, sector gear 10, free end 11, connecting rod 12, sector shaft 13 and indicating value set screw 14, on lower plate, be fixed with post 15, post 15 is fixed on sector gear is turned to when being in contact with it, and just in time is stuck in the outer peripheral recess of sector gear.
