A kind of this new multifunctional safe pressure gauge, which contrasts existing like product, following characteristics:Instrument protection function More, type selecting is convenient, instrument service life length, and anti-measured medium leakage, shockproof properties are good, have over-voltage protecting function, prevent tested Medium pulse pressure, easy to maintenance, compact-sized, leakage point is few, it is not necessary to type selecting, it is not necessary to attachment device, can reduce because adding The defects of filling attachment device increased leakage point.
Brief description of the drawings
Accompanying drawing described herein is used for providing to this new part for further understanding, forming the application, and this is new The schematic description and description of type is used to explaining new, does not form an improper restriction new to this.In the accompanying drawings:
Fig. 1 is the structural representation of this novel and multifunctional safety pressure gage.
Embodiment
To make the purpose, technical scheme and advantage of this new embodiment clearer, below in conjunction with this new embodiment Accompanying drawing, the technical scheme of this new embodiment is clearly and completely described.Obviously, described embodiment is that this is new The part of the embodiment of type, rather than whole embodiments.Based on the new embodiment of described sheet, ordinary skill The every other embodiment that personnel are obtained on the premise of without creative work, belong to this novel protected scope.
Referring to Fig. 1, the structural representation for this novel and multifunctional safety pressure gage preferred embodiment.
A kind of this new multi-purpose pressure meter includes watchcase 7 and watch crystal 1, and watchcase 7 forms a cavity with watch crystal 1 (degree of protection IP68), each meter unit is in cavity.Chamber rear is provided with isolating device 9, and cavity front portion is provided with quarter Instruction device 3,4 is spent, scale indication device 3,4 is provided with dial 2 away from the rear portion of the side of watch crystal 1, and the lower section of dial 2 is set It is equipped with instrument flexible member 6 and movement 5.The isolating device 9 is provided with isolation diaphragm 11, and isolation diaphragm 11 is divided into isolating device Isolation ward 10 and pilot room 12, measured medium enter instrument isolation ward 10, pilot by the junction 8 of watchcase 7 and external equipment Room 12 is full of pilot liquid, and pilot liquid is isolated diaphragm 11 with measured medium keeps apart, and pilot liquid is entered by damping hole 13, pressure guide hole Entering instrument flexible member 6, instrument element mobile terminal is connected with movement 5, and the machine mandrel of movement 5 is connected with scale indication device 3,4, The indicating graduation value before dial 2 of scale indication device 3,4.In normal measurement process, measured medium is set by watchcase 7 with external Standby junction 8 enters instrument isolation ward 10, and when the pressure was increased, measured medium promotes 11 guide pressure chamber of isolation diaphragm 12 Move, promote the pilot liquid of pilot room 12 to be flowed to the direction of damping hole 13, instrument flexible member 6 is flow to by pressure guide hole, makes elasticity Element expands, and its end produces displacement, and flexible member end has connecting rod to be connected with movement 5, the displacement of flexible member is transmitted to Movement, movement indicate carving scale indication device 3,4 is driven by the rotation of machine mandrel after the displacement amplification of flexible member On scale 2.Corresponding pressure scale is carved with dial.
Further, isolation diaphragm 11 is flexible sheet, if pilot room 12 and damping hole 13, pressure guide hole, instrument elasticity member Part 6 occurs leakage or during pilot liquid serious loss, and damping hole 13 is blocked in the displacement of isolation diaphragm 11, cause isolation diaphragm 11 no longer by Displacement is pressed, the diameter of damping hole 13 meets flexible sheet isolation ward side compression 100MPa, and pilot chamber pressure is barrier film in the case of 0 Piece 11 will not crush.When isolating device isolation ward be pressurized cause the guide pressure chamber displacement of isolation diaphragm 11, when instrument flexible member by When compressive strain reaches certain value, damping hole is blocked in the displacement of isolation diaphragm 11, even if the isolation ward side of isolation diaphragm 11 continues to increase Pressure, instrument flexible member do not receive the pressure that pressure guide hole transmits yet, when the reduction of isolation ward lateral pressure, less than pilot chamber pressure When, isolation diaphragm 11 can open damping hole normally to the direction displacement of isolation ward 10.
Further, pilot liquid is non-flammable explosive, non-corrosive liquid.
In one embodiment, when measured medium (isolation ward) has pulse, damping hole 13 can weaken isolation ward 10 pulses transmitted, extend time of the pressure of isolation ward 10 by damping hole.
In one embodiment, movement 5 is provided with stopping means and sector gear (not shown), stopping means limit The angle of position sector gear rotation.

In one embodiment, damping oil is full of in watchcase, to mitigate damage of the equipment vibrations to instrument.
A kind of this new multifunctional safe pressure gauge is by said structure, so as to realize following functions:
1st, when pressure reaches dial maximum, isolation diaphragm 11 is just moved at 13 mouthfuls of damping hole, blocks damping Aperture, when measured medium pressure continues increase, isolation diaphragm 11 is not producing displacement, and flexible member also no longer expands position Move, when measured medium pressure decreases below 6 expansive force of flexible member, flexible member expansive force by pilot liquid promote every From diaphragm 11 to the displacement of measured medium direction, open damping aperture, instrument by normal work, it is acted on be protective meter more than When instrument flexible member 6 bears Pressure maximum value, pressure no longer is transmitted to instrument flexible member 6, protective meter flexible member 6 is not Be stressed excessive damage.
2nd, when leakage pilot liquid occurs for the part after damping hole 13, isolation diaphragm 11 is moved at 13 mouthfuls of damping hole, is blocked up Aperture is firmly damped, prevents measured medium from breaking through isolation diaphragm, goes out outflow from leakage pilot liquid.In order to avoid there is security incident.
3rd, when measured medium has pulse, damping hole can weaken the pulse of measured medium transmission, extend tested The time that pressure medium passes through damping hole.Protective meter is not damaged by measured medium pulse.
3rd, meter movement stopping means, when instrument flexible member is occurred by external force effect that tip displacement is excessive causes movement to revolve Gyration is excessive, and stopping means can control the movement anglec of rotation, in order to avoid because the meter movement anglec of rotation is excessive, causes instrument to damage It is bad.
4th, pointer rotation tunable arrangement, when gauge pointer indicated value does not wait with actual pressure value, rotatable tunable arrangement, Until pointer indicated value is equal with actual measured value.
5. can prevent equipment from shaking the damage brought to instrument full of damping oil in watchcase, damping oil has lubrication, The rotating mechanism in instrument can be made to mitigate frictional force, accuracy of instrument is improved, make meter life longer.
It should be understood that although with reference to its exemplary embodiment, particularly shown to this new carry out and description, It should be understood by those skilled in the art that without departing substantially from by as defined in the claims new spirit and model Under conditions of enclosing, the change of various forms and details can be carried out wherein, can carry out any combination of various embodiments.
