Description
Technical field
The invention belongs to MACHINERY JOINT fields, are related to a kind of for connecting the adjustable company of two-tube pressure gauge and gas source
Connection device.
Background technique
Currently, being usually two-tube pressure gauge for the pressure gauge on railway locomotive, there are two interfaces for the pressure gauge
It with a dial plate, sets that there are two pointers in dial plate, can indicate the pressure for the gas that two interfaces are accessed simultaneously.It is double in calibration
During pipe pressure instrument, need that two-tube pressure gauge and external air source are carried out air circuit connection by attachment device, it is external
Gas source provides the gas of certain pressure to two-tube pressure gauge by attachment device, and by reading on two-tube pressure gauge two
The indicating value of pointer is to calibrate two-tube pressure gauge；However two-tube pressure gauge is there are many specification, the direction of two interfaces and between
Spacing be all not quite similar, the height of two interfaces is also not fixed, and the screw thread of interface and sealing means also there are many.Therefore exist
When calibrating two-tube pressure gauge, air circuit connection is very inconvenient between external air source and two-tube pressure gauge.
Three-way connection is generallyd use in the prior art to add the connection type of hose or connect using the threeway seat of constant spacing
Device realizes the air circuit connection between gas source and two-tube pressure gauge, wherein three-way connection adds the connection type of hose due to soft
Pipe is flexible connection, and position between two-tube pressure gauge and three-way connection can not be made to fix, can not be to being detected two-tube pressure gauge
Support is provided；There are three connector, two of them quick union and two-tube pressure gauge air circuit connections for threeway seat attachment device tool, also
There are an adapter and gas source air circuit connection, its shortcoming is that: (1) between two quick unions in threeway seat attachment device
Spacing can not be adjusted, and can only adapt to a kind of two-tube pressure gauge of interface spacing；(2) two of threeway seat attachment device connect fastly
The height of connector is identical, two slightly different double-tube pressure gauges of interface height may cause after connecting after poor sealing
Fruit；(3) position of adapter is fixed, therefore can only adapt to a kind of double-tube pressure gauge in direction.
In conclusion can be used for calibrating various types of two-tube pressure it is necessory to provide a kind of adjustable connecting device
Instrument.
