Description
Technical field
The present invention relates to a kind of pipeline pressure test detection technique field, especially a kind of metal hose Multifunction pressure tester.
Background technique
Metal hose is the important composition component in modern industrial equipment connecting pipeline.Metal hose be used as electric wire, cable,
The wire and cable protection pipe of instrument and meter for automation signal and civilian shower hose, specification is from 3mm to 150mm.Small diameter metal hose
(internal diameter 3mm-25mm) is mainly used for the sense line protection of precision optics ruler, industrial sensor route protection.Metal hose produces
Product include defeated oil suction hose, steam sebific duct, sand blast hose, defeated chemical suction hose, food hose, oxygen rubber pipe and various special-shaped glue
Pipe etc..It is widely used in the industries such as machinery, chemical industry, petroleum, metallurgy, food.
The pressure limit of pressure tight metal hose is how many: the pressure limit of hose is generally PN0.6-32.0Mpa.Highest
Up to 42.0MPa.Metal hose is the pressure parts that hose is mounted in pressure piping, while playing sheath to bellows,
According to the pressure size and application places in pipeline, stainless steel wire or the steel band that one or more layers may be selected are woven.
Since the latus rectum of shallow ring metal bellows is big, pressure-bearing is high, heat-resisting, flexible, corrosion-resistant, long service life, and
It is widely used in a variety of pipelines such as room inlet pipeline, fuel gas pipeline, solar water heater hydraulic pipeline, fire main.
Presently used metal bellows is generally the finished product of various different lengths, selects to use when for installation, since scene is pacified
It needs the length of bellows to be difficult to be determined in advance when dress, generally requires the bellows for taking different lengths specification.With bellows
The raising of manufacturing technology, the country can produce 300 meters of long bellowss, be such as able to achieve on-site cutting and ensure bellows with it is other
Pipe fitting is convenient and fast connection and safe and reliable, fixed that expansion metal bellows significantly is used field.China national intellectual property
A kind of for field erected metal bellows, the nut including tube body and set on it is disclosed on website, the tube body
End forms a boss, and the outer diameter of boss is greater than the aperture of nut inner hole, clamps a ring at the tube body wave trough on the inside of boss
Shape open metal liner.When metal bellows is connect with other tube bodies, it is provided with advantage convenient and efficient, at low cost, still
Its bonding strength is relatively low, when tube body when pulled, bellows body and the easy overstress in nut coupling part, leakproofness drop
It is low, and generate gas leakage etc., to reduce the safety and service life when corrugated flexible hose uses.In addition the outer diameter of corrugated flexible hose
Small 2mm or more is generally required than the internal diameter of pipe screw thread, limits its use scope.

Fuel gas transmission stainless steel ripple hose connection device ", the axial tensile-strength of the attachment device is big；The high advantage of leakproofness,
Inner space has been saved, larger outer diameter corrugated flexible hose is enabled to use the pipe screw thread of standard.
However even in this way, metal bellows before factory and after a period of use, is both needed to tensile property, close
Sealing property and corrosion resistance can be carried out detection.Especially joint area, it is easier to lead to that sealing performance is not good after corrosion.Mesh
Before, tensile property, sealing performance and the corrosion resistance detection of metallized metal hose need to be sent to specified department and be detected, and examine
Survey costly, the time is long, and detection device is inconvenient for operation.It really is able to accomplish that the enterprise of the requirement is seldom in factory, need
Configure dedicated place and equipment.
In addition, the independent performance indicator that specific office can only also carry out tensile property, sealing performance and corrosion resistance is surveyed
Examination, cannot simulate virtual condition, test data reliability is low.
