Description
Technical field:
This utility model relates to a kind of densimeter with overpressure alarm function, is especially suitable for
The detection of SF6 gas.
Background technology:
Densimeter that now both at home and abroad centering pressure SF6 gas uses is the highest, and to be only limited to two point defeated
Going out, i.e. one docking point is alarm signal output, and another exports for block signal, but in reality
During border uses, the equipment of middle pressure industry also needs to an over voltage alarm output, during reason is
The air chamber pressure of pressure equipment is the highest (being usually no more than 2bar), and its air chamber itself is to internal pressure
Ability to bear also only reach 1.5 times of its maximum allowable internal pressure, therefore if owing to people
For reason to equipment inflation too much, during its equipment cut-offs, can be because producing big
The heat of amount, makes pressure be substantially increased and exceedes its allowable stress, do not having the feelings of over voltage alarm
Under condition, it is likely that cause the blast of equipment.
Summary of the invention:
Technical problem to be solved in the utility model is: provide a kind of with overpressure alarm function
Densimeter, to solve problems faced in industry.
In order to solve above-mentioned technical problem, this utility model is to be achieved through the following technical solutions
: a kind of densimeter with overpressure alarm function, it is provided with central tube, described central canal
The left side in road connects Bourdon tube.
Being welded with connection sheet on described Bourdon tube, described connection sheet is connected on bimetal leaf,
Described bimetal leaf is connected to movement and connects on sheet.
Described movement connects sheet and drives movement internal gear to rotate, and described movement internal gear is provided with
Movement rotating shaft, described movement rotating shaft is provided with pointer.
Described pointer push pointer push rod rotates, and pointer push rod promotes electric contact moving contact to connecting
Put on static contact thus produce the signal of telecommunication.
The described signal of telecommunication is sent on glass-encapsulated joint by wire, described glass-encapsulated joint
With transmitting alarm device by the signal of telecommunication.
As preferably, described glass-encapsulated joint is seven cored structures.
As preferably, the current value of the described signal of telecommunication is 1A
Compared with prior art, of the present utility model having the beneficial effect that arranges Bourdon tube, passes through
The deformation of Bourdon tube carrys out be dynamically connected sheet, bimetal leaf, movement of band and connects the operation of the parts such as sheet,
Thus drive electric contact movable contact and the connection of junction point stationary contact, thus produce the signal of telecommunication, enter
And the signal of telecommunication is sent to alarm device, it is achieved thereby that densitometric overpressure alarm function, this
Utility model simple in construction, certainty of measurement is high, and cost is relatively low.
Accompanying drawing illustrates:
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
In figure: 1, central tube；2, Bourdon tube；3, sheet is connected；4, bimetal leaf；5、
Movement connects sheet；6, movement internal gear；7, movement rotating shaft；8, pointer；9, pointer push rod；
10, electric contact moving contact；11, junction point static contact；12, glass-encapsulated joint.
Detailed description of the invention:
Below in conjunction with the accompanying drawings and this utility model is described in detail by detailed description of the invention: according to
A kind of densimeter with overpressure alarm function shown in Fig. 1 and Fig. 2, is provided with central tube
1, the left side of described central tube 1 connects Bourdon tube 2.
Being welded with connection sheet 3 on described Bourdon tube 2, described connection sheet 3 is connected to bimetallic
On sheet 4, described bimetal leaf 4 is connected to movement and connects on sheet 5.
Described movement connects sheet 5 and drives movement internal gear 6 to rotate, on described movement internal gear 6
It is provided with movement rotating shaft 7, described movement rotating shaft 7 is provided with pointer 8.
Described pointer 8 push pointer push rod 9 rotates, and pointer push rod 9 promotes electric contact moving contact
On 10 to junction point static contact 11 thus produce the signal of telecommunication.
The described signal of telecommunication is sent on glass-encapsulated joint 12 by wire, described glass-encapsulated
Joint 12 is with transmitting alarm device by the signal of telecommunication.
Described glass-encapsulated joint 12 is seven cored structures.
The current value of the described signal of telecommunication is 1A.
During use, gas leading to central tube 1, gas enters into ripple by central tube 1
Stepping in pipe 2, when air pressure raises, Bourdon tube 2 will start expansion, owing to connecting sheet 3 is
It is welded on Bourdon tube 2, at this moment connects sheet 3 and bimetal leaf 4 will be driven to run, work as gas
When pressure raises, gas temperature also can change, when gas temperature deviates 20 degrees Celsius, double
Sheet metal 4 will extensional deformation or dilatating and deformable, at this moment bimetal leaf 4 will drive movement
Connecting sheet 5 to run, movement connects sheet 5 and drives movement internal gear 6 to rotate, described movement internal tooth
It is provided with movement rotating shaft 7 on wheel 6, described movement rotating shaft 7 is provided with pointer 8, described finger
Pin 8 push pointer push rod 9 rotates, and pointer push rod 9 promotes electric contact moving contact 10 to connection
Putting on static contact 11 thus produce the signal of telecommunication, the described signal of telecommunication is sent to glass by wire and seals
On joint 12, described glass-encapsulated joint 12 is with transmitting alarm device by the signal of telecommunication.
It is emphasized that: be the most only preferred embodiment of the present utility model, not to this reality
Make any pro forma restriction with novel, every according to technical spirit of the present utility model to more than
Any simple modification, equivalent variations and the modification that embodiment is made, all still falls within this utility model
