Abstract
The utility model relates to a non-destructive tester used for detecting non-destructive and sealing of pipe fittings. One end of an outer frame of the non-destructive tester of pipe fittings is fixed with a hydraulic cylinder which is connected with an oil pump; a front end of a piston rod of the hydraulic cylinder is connected with a movable sealing head and the other end of the outer frame is fixed with a fixed sealing head which is at the same shaft as the movable sealing head; an exhaust valve which is communicated with an inner cavity of the movable sealing head is arranged outside the movable sealing head and a water pipe for intaking and exhausting water which is connected with a pressure-test water pump through a pressure-protective switch and is communicated with an inner cavity of the fixed sealing head is arranged on the tail part of the fixed sealing head. The utility model not only has simple and reasonable structure and convenient use but also has wide application range.
Description
Technical field
The utility model relates to a kind of being used for pipe fitting be can't harm the pipe fitting non-destructive testing machine that sealing detects that injures.
Background technology
For serial pipe fitting, the pipe fitting of high pressure resistant purposes is particularly arranged, generally need carry out not damaged, impermeability test.Existing test unit mostly is specialized equipment, and limitation is stronger, can't be applicable to the serial pipe fitting of different length, various outer diameter.In addition, adopt the method that experimentizes behind the simple solder up in addition, not only process of the test troublesome poeration, and cost is also higher.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, easy to operate, and pipe fitting non-destructive testing machine applied widely.
Pipe fitting non-destructive testing machine of the present utility model has an outside framework, be fixed with a hydraulic jack that is connected with oil pump at outside framework one end, the piston rod front end of hydraulic jack is connected with a movable sealing head, the other end at outside framework is fixed with a fixing seal head coaxial with the movable sealing head, a vent valve that communicates with movable sealing head inner chamber is installed in movable sealing head outside, and the afterbody of fixing seal head also is equipped with an intake-discharge pipe that communicates with fixing seal head inner chamber, and intake-discharge pipe is connected with the pressure testing water pump by a pressurize switch.In addition, in the periphery of fixed connector several discharging push rods can be installed also, discharging push rod afterbody is equipped with compression spring, and its front end withstands on the end face of test specimen at the trial.
The utility model is not only simple and reasonable, and is easy to use, and can satisfy the testing requirements of different size by the position dimension of adjusting seal head, thereby applied widely.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, pipe fitting non-destructive testing machine has an outside framework 1, be fixed with a hydraulic jack 2 that is connected with oil pump 3 at outside framework one end, piston rod 4 front ends of hydraulic jack are connected with a movable sealing head 5, be fixed with a fixing seal head 6 coaxial at the other end of outside framework 1 with movable sealing head 5, a vent valve 7 that communicates with movable sealing head inner chamber is installed in movable sealing head outside, and the afterbody of fixing seal head is equipped with an intake-discharge pipe 8 that communicates with fixing seal head inner chamber, and intake-discharge pipe is connected with pressure testing water pump 10 by a pressurize switch 9.
During test, test specimen 13 is placed between movable sealing head 5 and the fixing seal head 6, pressurize to seal head by oil pump 3 earlier, make pipe fitting sealed at both ends, supply water to tube intracavity by pressure testing water pump 10 again, and by the air in the vent valve 7 emptying pipe fittings, adjust hydraulic pressure to test pressure, close the pressurize switch after 9 pressurize a period of times, check manometric situation of change, determine that by the variation of hydraulic pressure pipe fitting has not damaged.
In addition, in the periphery of fixed connector 6 several discharging push rods 11 are installed, discharging push rod afterbody is equipped with compression spring 12, and its front end withstands on the end face of test specimen 13 at the trial, can make test specimen and fixing seal head break away from, take out when off-test.
