Problems solved by technology

[0002] The grooved pipe joint for fire protection requires that the water pressure is 0.2MPa to maintain for 2 minutes without a sealing ring, and the leakage at the joint must not exceed the specified value. Now this test is cumbersome and labor-intensive. It is considered that there are many interference factors and the quality and efficiency of the test Low, in the prior art, there is no leakage test device without sealing ring that is more suitable for grooved pipe joints for fire protection

Abstract

The invention relates to the technical field of product detection, and particularly discloses a groove type pipe joint seal ring-free leakage testing device for firefighting. The groove type pipe joint seal ring-free leakage testing device for firefighting comprises a circulating water channel; the device is characterized in that a support A, a support B and a support C are installed on the circulating water channel in sequence from left to right, a left end sealed pipe is arranged on the support A, a right pipe is erected on the support C, and a pipe joint specimen is installed between the left end sealed pipe and the right pipe; a water collection chamber composed of a water collection chamber mobile end and a water collection chamber fixed end sleeves the periphery of the pipe joint specimen, a telescopic shaft motor is installed at a left end sealed pipe end, and a motor shaft of the telescopic shaft motor is connected with the water collection chamber mobile end; a bracket for installing an electronic scale is arranged on the circulating water channel, and a container is placed on the electronic scale. The device is simple in structure, reasonable in design, experimenter operation and man-made interference factors are reduced, detection automation is achieved, and the detection quality and efficiency are improved.

Description

(1) Technical field [0001] The invention relates to the technical field of product detection, in particular to a leakage test device for a grooved pipe joint for fire protection without a sealing ring. (2) Background technology [0002] The grooved pipe joint for fire protection requires that the water pressure is 0.2MPa to maintain for 2 minutes without a sealing ring, and the leakage at the joint must not exceed the specified value. Now this test is cumbersome and labor-intensive. It is considered that there are many interference factors and the quality and efficiency of the test Low, in the prior art, there is no sealing ring leakage test device that is more suitable for grooved pipe joints for fire protection. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a leak test device for fire-fighting grooved pipe joints without sealing rings, which is simple in structure, convenient to use and hi...
