Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.
[0027] Such as figure 1 As shown, a metal hose and joint tensile strength detection device for gas transportation is used to detect the tensile strength of the metal hose 20 with joints to be tested; it includes a fatigue testing machine 10, an electric heating wire 30, an explosion-proof protective cover 40 and Pressurized water pump 50.
[0028] The metal hose 20 with joints to be tested includes a metal hose segment 21 , an intermediate joint 22 , a three-way joint 23 and a tail end joint 24 . The number of metal hose sections is at least two, and can be three, four or more, depending on the actual needs
[0029] length to connect.
[0030] Two adjacent metal hose sections are sealed and connected by an intermediate joint. The intermediate joint here can be used
[0031] The connection device described in 201320065701...

The invention relates to a device for detecting the tensile strength of a metal hose and a joint for fuel gas transmission, which comprises a fatigue testing machine, an electric heating wire, an explosion-proof protective cover and a pressurized water pump, and is characterized in that the fatigue testing machine comprises an upper stretching head and a lower stretching head which are arranged ina coaxial manner; two tail-end positioning disks are respectively connected with the upper stretching head and the lower stretching head; the explosion-proof protective cover is arranged at the periphery of a to-be-detected metal hose with a joint in a sleeved manner, the electric heating wire is uniformly arranged at the inner wall surface of the explosion-proof protective cover, and the outer wall surface of the explosion-proof protective cover is coated with a thermal insulation layer; the pressurized water pump is connected with the remaining joint of a three-way joint through a high pressure rubber hose; the other end of the pressurized water pump is connected with a water tank; and the high pressure rubber hose is provided with a pressure sensor connected with the pressurized waterpump. The device can perform independent or joint detection on the tensile strength, the sealing performance and the high temperature resistance of the metal hose, can simulate a performance test under an extreme condition of the joint of a tensile force and a high temperature, and is simple to operate and safe and reliable in testing.
Description
technical field [0001] The invention relates to the field of metal hose manufacturing, in particular to a metal hose for gas transmission and a device for detecting tensile strength of a joint. 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 pressure range of the pressure-resistant m...
