Embodiment 1

[0016] As shown in the figure, a metal hose hydraulic test device is manufactured and installed, which includes a pressure test pump 1 and a pressure gauge 2, and also includes a frame body 3, a pressure test head 4 and a pressure test tail 5.

[0017] The frame body 3 includes a frame column 31 and a pipe groove 32, and the pipe groove 32 is installed on the frame column 31 at both ends of the frame body 3. At both ends of the frame body 3, the frame column 31 at one end is higher than the frame column 31 at the other end. One side of the pipe groove 32 is higher than the other side, forming a pipe groove low side 33 and a pipe groove high side 34; the pipe groove 32 is used for placing metal hoses to be tested.

[0018] The pressure test head 4 is fixedly installed on the outside of the lower side 33 of the pipe groove, and the pressure test tail end 5 is movably installed in the pipe groove 32; the pressure test tail end 5 can be adjusted in real time according to the length...

Embodiment 2

[0022] On the basis of Embodiment 1, the middle section of the pressure tube 21 is turned into a spring shape to form a spring tube buffer strip 22 so as to buffer and protect the pressure gauge 2 .

[0023] During use, one end of the metal hose is connected to the flange 6 on the tail end 44 of the head bobbin, and the other end is connected to the flange 6 of the head end 54 of the tail bobbin, and then the tail end seat 51 is placed in the pipe groove 31, and metal hose just constitutes a closed hydraulic test system together with pressure test head end 4, pressure test tail end 5 like this. During the test, open the valve of the water inlet pipe 43 and the valve of the exhaust pipe 53, the water inlet pipe 43 enters the water and flows into the metal hose through the head end bobbin 42, and the gas in the metal hose is discharged from the exhaust pipe 53. The horizontal position of the pressure test end 5 is higher than the horizontal position of the pressure test head 4, ...

Abstract

A hydraulic test device for a metal hose comprises a hydraulic test pump, pressure gages, a frame, a hydraulic test head end and a hydraulic test tail end, wherein one side of the frame is higher than the other side, the hydraulic test head end is fixedly mounted on the outer side of the low side of a hose groove, and the hydraulic test tail end is movably mounted in the hose groove; the middle sections of pressure pipes are rotationally folded into a spring shape. The hydraulic test device for the metal hose has the beneficial effects that the hydraulic test pump is directly adopted for hydraulic test, equipment is simple, and practicability is high; the hydraulic test head end is lower than the hydraulic test tail end, so that water entering from the hydraulic test head end can exhaust all gas in the metal hose through the hydraulic test tail end, and the hydraulic test effect is improved effectively; the hydraulic test tail end is movably mounted and connected in the hose groove and can be adjusted according to the length of the metal hose; spring buffer zones are arranged on the pressure pipes, so that impact of hydraulic pressure to the pressure gauges can be reduced effectively, and the service lives of the pressure gauges can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of pipeline pressure detection, in particular to a metal hose hydraulic pressure test device. Background technique [0002] In the liquid gas industry, a large number of metal hoses are used. In actual use, it is necessary to carry out regular pressure tests on the metal hoses and perform corresponding pressure tests. [0003] In the past, it had to be transported over long distances to designated departments for testing, which was very inconvenient. Therefore making a kind of simple and practical, easy to operate, scientific and effective detection test device seems very necessary. Contents of the invention [0004] The technical problem to be solved by the present invention is to develop a simple and practical method according to the production testing needs of the company, which uses a pressure test pump to press water into the metal hose, pressurizes the metal hose and performs pressure detection, whi...
