Description
Technical field
The utility model belongs to MACHINERY JOINT field, be related to it is a kind of be used to connecting two-tube manometer and source of the gas can
Adjust attachment means.
Background technology
The manometer being presently used on railway locomotive is usually two-tube manometer, and the manometer has two interfaces
With a dial plate, dial plate is interior to be provided with two pointers, can indicate the pressure for the gas that two interfaces are accessed simultaneously.It is double in calibration
It is connected during pipe pressure instrument, it is necessary to which two-tube manometer is carried out into gas circuit with external air source by attachment means, it is outside
Source of the gas provides the gas of certain pressure to two-tube manometer by attachment means, and by reading on two-tube manometer two
The indicating value of pointer is to calibrate two-tube manometer；But two-tube manometer has a plurality of specifications, the direction of two interfaces and between
Spacing be all not quite similar, the height of two interfaces is not also fixed, and the screw thread of interface also have with sealing means it is a variety of.Therefore exist
When calibrating two-tube manometer, gas circuit connection is very inconvenient between external air source and two-tube manometer.
Generally use three-way connection is added the connected mode of flexible pipe or connected using the threeway seat of constant spacing in the prior art
Device realizes the gas circuit connection between source of the gas and two-tube manometer, wherein, three-way connection adds the connected mode of flexible pipe due to soft
Pipe is flexible connection, can not fix position between two-tube manometer and three-way connection, can not be to being detected two-tube manometer
Support is provided；Threeway seat attachment means have three joints, and two of which quick union is connected with two-tube manometer gas circuit, also
There is an adapter to be connected with source of the gas gas circuit, its shortcoming is：(1) between two quick unions in threeway seat attachment means
Spacing can not be adjusted, and it can only adapt to a kind of two-tube manometer of interface spacing；(2) two of threeway seat attachment means connect soon
The height of joint is identical, may be caused after connecting after poor sealing for the highly slightly different double-tube pressure gauge of two interfaces
Fruit；(3) position of adapter is fixed, therefore can only adapt to a kind of double-tube pressure gauge in direction.
In summary, it is necessory to provide a kind of adjustable connecting device, it can be used for calibrating various types of two-tube pressure
Instrument.
