Gas bellows air-tightness detection device and its detection method.
Background technique
Natural gas metal hose is made of bellows, net cover, connector three parts, and main body is bellows.Bellows sheet
Body has good flexibility, because the longitudinal rigidity and bending stiffness of bellows are small, since the material of production hose major part is
Austenitic stainless steel is used, hereby it is ensured that the excellent temperature tolerance of hose and corrosion resistance, the operating temperature range of hose is extremely wide,
For-196-600 degree, the hose used by pipeline institute logical medium corrosivity selection be applicable in the stainless steel trade mark, that is, can guarantee soft
The corrosion resistance of pipe.Thus it can successfully work in specified bending radius the net cover (steel band of natural gas metal hose outer layer
Net cover or wire sets) booster action is played, it is metal hose " skeleton ", can is one layer, two according to hose bore, pressure difference
Layer or three layers.Net cover is the main compression-member of metal hose, and metal hose is made to have certain bearing capacity, and natural gas metal is soft
Effective braiding net sleeve strengthens protection, with higher bearing capacity.The connection at natural gas metal hose both ends is general
It is made as flanged joint, the material of flange uses carbon steel and stainless steel, and material is determined according to product using position.
Due to the particularity of natural gas, the airtight of the natural gas metal hose bellows especially therein of natural gas is transmitted
Property just seem particularly significant, the detection of the existing air-tightness to bellows be typically all using bellows is put into water,
Then it is passed through pressure-air in bellows, then observes whether generate bubble outside bellows to judge the airtight of bellows
Property.This method bubble first is not easy to observe, and especially for the observation of tiny bubble, will result in erroneous judgement in this way.
