Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0031] Such as figure 1 As shown, a metal hose multifunctional pressure test device includes a tensile machine 10 , a salt spray corrosion device 30 , an explosion-proof protective cover 40 and a sealing performance detection device 50 .

[0032] The tensile machine includes a left stretching head 11 and a right stretching head 12 coaxially arranged.

[0033] The two ends of the pressure test metal hose 20 are respectively connected with the left stretching head and the right stretching head.

[0034] The pressure test metal hose includes a metal hose segment 21 , an intermediate joint 22 , a tee joint 23 and an end sealing joint 24 . The number of metal hose segments is at least two, and the two adjacent metal hose segments are sealed and connected by an intermediate joint; the three-way joint is set at one end of the pre...

Abstract

The invention discloses a method for testing the sealing performance of a metal hose in axial tension and corrosion state. The method comprises a step 1 of injecting a corrosive medium; a step 2 of installing a pressure test metal hose; a step 3 of installing an explosion-proof protective cover; a step 4 of detecting performance testing; a step 41 of detecting sealing performance; a step 42 of detecting tensile performance; a step 43 of detecting sealing performance under a corrosion condition; and a step 44 of detecting tensile performance under a corrosion condition. The method can separately or jointly detect the tensile performance, the sealing performance and the corrosion resistance of the metal hose, can simulate a performance test under an extreme condition where the tension forceand the salt spray corrosion are combined, and is easy to operate and safe and reliable in test.

Description

technical field [0001] The invention relates to the technical field of pipeline pressure testing and detection, in particular to a method for testing the sealing performance of metal hoses under shaft tension and corrosion conditions. Background technique [0002] Metal hose is an important component in the connection pipeline of modern industrial equipment. Metal hoses are used as wire and cable protection tubes for wires, cables, automated instrument signals, and civil shower hoses, with specifications ranging from 3mm to 150mm. Small-diameter metal hose (3mm-25mm inner diameter) is mainly used for the protection of sensing lines of precision optical rulers and industrial sensor lines. Metal hose products include oil suction hose, steam hose, sandblasting hose, acid and alkali suction hose, food hose, oxygen blowing hose and various special-shaped hoses. Widely used in machinery, chemical industry, petroleum, metallurgy, food and other industries. [0003] What is the p...
