the top plate 306, the sleeve seat 308 and the pressure spring 310 are utilized to press the pressing column 309 and the sealing disc at the bottom of the pressing column into the pipe fitting from the upper opening of the cylindrical pipe fitting, and the detachable sealing discs have various types and can be replaced by specifications with the same size as the inner wall of the pipe fitting; the compression spring 310 is a strong cylindrical spring.
Because the upper opening and the lower opening of the cylindrical pipe are respectively sealed by the rubber coating on the surface of the bracket 204 and the rubber coating on the edge of the sealing disc, when the top plate 306 drives the pressing column 309 and the sealing disc to move downwards, and when the inside of the cylindrical pipe is pressurized, if the cylindrical pipe does not leak, the sealing disc extends into the pipe and cannot move, but the sealing disc and the pressing column 309 extrude the pressure spring 310 under the high-pressure environment, so that the pressing column 309 is extruded into the sleeve seat 308;
at this time, the pressure applied to the socket 308 detected by the pressure sensor 307 is corresponding to the elastic force generated by the deformation of the compression spring 310, and can be known according to hooke's law:
that is, the elastic force and the deformation are in positive correlation and linear positive correlation, so that the elastic force can be represented by the deformation;
measuring the downward movement distance of the top plate 306, wherein the downward movement distance of the top plate 306 is the deformation amount of the pressure spring 310 under the default condition of no leakage, the deformation amount is multiplied by the elastic coefficient to obtain the elastic force, the elastic force is compared with the pressure measured by the pressure sensor 307, and if the difference between the elastic force and the pressure measured by the pressure sensor is not large and is within a reasonable error range, the cylindrical pipe fitting is indicated to have no leakage;
the errors mainly include the friction between the projection 311 and the groove 312, the friction between the pressing column 309 and the sleeve seat 308, and the friction between the sealing disk and the inside of the cylindrical pipe fitting, and can be reduced by smearing lubricating oil between the projection 311 and the groove 312, between the pressing column 309 and the sleeve seat 308, and between the sealing disk and the inside of the cylindrical pipe fitting.
Obviously, if there is a leak in the cylindrical pipe, when the sealing disc extends into the pipe, due to the leak in the pipe, the partial compressed air will overflow from the leak in the high-pressure environment, resulting in the return of the compression spring 310 by a small length;
at this time, the downward movement distance of the top plate 306 is the deformation of the compression spring 310, the elastic force converted by the deformation is larger than the pressure actually measured by the pressure sensor 307, and the difference between the two inevitably exceeds the normal error range, so that the leakage of the pipe fitting can be obtained.
Note that when the leak crack is fine, the leak occurs only in a high-pressure environment, and does not occur when the pressure is not large; at the moment, whether the pipe fitting leaks or not can not be accurately tested by the conventional leak detection device and means; the scheme provided by the invention is really suitable for the situation, so that the scheme is suitable for the leakage test of the high-pressure pipe fitting.
