Description
Technical field
This utility model belongs to pipe fitting technical field, is related to a kind of corrugated tube.
Background technology
Corrugated tube refers to the tubular elastomeric sensing element being connected into foldable wrinkle piece along folding retractable direction.Corrugated tube
Instrument and meter is widely used, is mainly used for the measuring cell as pressure measuring instruments, convert pressure into displacement or
Power.Ripple tube wall is relatively thin, and sensitivity is higher, and measurement range is tens of handkerchiefs to tens of MPas.Its opening is fixed, sealed end
It is in free state, and the helical spring using auxiliary or reed increase elasticity.During work internally in the presence of pressure along pipe
Sub- elongated lengthwise, makes movable end generation become the displacement of certain relation with pressure.Movable end drives pointer can directly indicate
The size of pressure.Corrugated tube is usually combined with displacement transducer and constitutes the pressure transducer being output as electricity, sometimes also uses
Make isolation element.Because the stretching, extension of corrugated tube requires larger volume to change, therefore its response speed is less than Bourdon tube.Ripple
Pipe is suitable to measure low pressure.
Quick change bellows expansion joint is that the interface at corrugated tube two ends respectively connects a hydraulic quick coupler, the end of ripple interface tube
Face, hydraulic quick coupler end face all vertical with corrugated tube axis.Such ripple interface tube is referred to as the positive interface of corrugated tube, will so
Hydraulic quick coupler referred to as just connecing hydraulic quick coupler.However, corrugated tube actually used during, corrugated tube can not possibly be completely along certain
One straight line wiring；For the needs that move towards of pipeline when necessary, corrugated tube also likely to be present bending.
The utility model patent of Application No. 201520576030.7 discloses a kind of quick change mitered bellows expansion joint,
The connection of of corrugated tube positive interface is just connecing hydraulic quick coupler, the inclined interface of another interface of corrugated tube, and described inclination connects
Mouth refers to that the end face of inclined interface forms the angle less than 90 degree with the end face of positive interface, in the outer wall weldering of corrugated tube inclined interface
Connect mitered hydraulic quick coupler, the end face of mitered hydraulic quick coupler, all parallel with the end face of inclined interface.
By above-mentioned expansion joint, though enabling to be attached two sections of corrugated tubes, and two sections of corrugated tubes exist in junction
Bending, it is possible to achieve it connects up along a certain straight line completely.But, when connecting two sections of corrugated tubes by this expansion joint, connection finishes
The angle between two sections of corrugated tubes afterwards is fixed all the time, thus arbitrarily two sections cannot be changed according to the needs that site operation is installed
Angle between corrugated tube, thus increasing the installation difficulty of corrugated tube, causes the waste of corrugated tube.
Additionally, in prior art, when corrugated tube is attached with corrugated tube, generally will not between corrugated tube and corrugated tube
Setting gasket seal, even if be provided with gasket seal, then these gasket seals also cannot be applied to and can arbitrarily adjust two sections
In the helical bellows of corrugated tube angle.
