Description
Technical field
Instrument field is the utility model is related to, especially a kind of vacuum meter of more installation stations.
Background technology
Vacuum meter is divided into pressure vacuum meter and pressure vacuum gauge.Pressure vacuum gauge：On the basis of atmospheric pressure, for measuring
Less than the instrument of atmospheric pressure.Pressure vacuum meter：On the basis of atmospheric pressure, for measuring the instrument larger and smaller than atmospheric pressure
Table.
Pressure has two kinds of method for expressing：A kind of is using the pressure represented by absolute vacuum as benchmark, referred to as absolute pressure；
Another kind is using the pressure represented by atmospheric pressure as benchmark, referred to as relative pressure.Due to measured by most of pressure instrumentations
Pressure be all relative pressure, therefore relative pressure is also referred to as meter pressure.When absolute pressure is less than atmospheric pressure, in used vessel
Absolute pressure represents less than the numerical value of an atmospheric pressure, is referred to as " vacuum, only one is filled on the watchcase of present vacuum meter
Gas access port, use are relatively simple.
The content of the invention
The purpose of this utility model is to solve the defects of prior art is present, there is provided a kind of vacuum of more installation stations
Table.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of vacuum meter of more installation stations, including watchcase, are provided with dial plate, dial plate, which is provided with, rotatably to be referred in watchcase
Pin, the middle part of dial plate are provided with the rotary shaft being connected with pointer, are provided with watchcase positioned at the lower section of dial plate multiple with rotating axis connection
Bourdon tube, bourdon tube includes spire and vertical portion, and the spire of multiple bourdon tubes is arranged on the rotating shaft, and vertical portion exists
Uniformly arranged in watchcase, multiple inflation inlets corresponding with the vertical portion port of bourdon tube are provided with the side face of watchcase.
A kind of vacuum meters of above-mentioned more installation stations, the side where being located at pointer on dial plate are provided with scale.
A kind of vacuum meter of above-mentioned more installation stations, the spire of bourdon tube and vertical portion are integrally formed.
A kind of vacuum meter of above-mentioned more installation stations, the inflation inlet are uniformly arranged on the side face of watchcase.
A kind of vacuum meter of above-mentioned more installation stations, the bourdon tube quantity is five.
The beneficial effects of the utility model are：Lower section in the watchcase of the vacuum meter positioned at dial plate is provided with multiple and rotary shaft
Connecting spring pipe, bourdon tube include spire and vertical portion, and the spire of multiple bourdon tubes is arranged on the rotating shaft, vertical portion
Uniformly arranged in watchcase, multiple inflation inlets corresponding with the vertical portion port of bourdon tube are provided with the side face of watchcase, this is true
Empty table can reach the purpose of barometric surveying in the extraneous tracheae of different inflation inlet accesses, and installation Tool Position Comparision is more, behaviour
Work gets up convenient, fast.

Lower section is provided with multiple bourdon tubes 5 being connected with rotary shaft 4, and bourdon tube 5 includes spire 51 and vertical portion 52, multiple bourdon tubes 5
Spire 51 be set in rotary shaft 4, vertical portion 52 is uniformly arranged in watchcase 1, on the side face of watchcase 1 be provided with it is multiple
Inflation inlet 6 corresponding with the port of vertical portion 52 of bourdon tube 5.
In the utility model, scale, the He of spire 51 of bourdon tube 5 are provided with positioned at the side where pointer 3 on dial plate 2
Vertical portion 52 is integrally formed, and inflation inlet 6 is uniformly arranged on the side face of watchcase 1, and the quantity of bourdon tube 5 is five.
Lower section in the watchcase 1 of the vacuum meter positioned at dial plate 2 is provided with multiple bourdon tubes 5 being connected with rotary shaft 4, bourdon tube
5 include spire 51 and vertical portion 52, and the spire 51 of multiple bourdon tubes 5 is set in rotary shaft 4, and vertical portion 52 is in watchcase
Uniformly arranged in 1, multiple inflation inlets 6 corresponding with the port of the vertical portion of bourdon tube 5 52 are provided with the side face of watchcase 1, this is true
The tracheae that empty table can access the external world in different inflation inlets 6 can reach the purpose of barometric surveying, and installation Tool Position Comparision is more, grasps
Work gets up convenient, fast.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
