Technical Problem

[0004]但是，传统气密性试验装置的操作便利性较差，工作人员在使用时需要频繁的拆装螺母才能对待测管件接头进行固定，同时在检测过程中还很容易因螺母过紧或拧紧力不足而导致检测结果出现误差，因此无法满足实际使用需求

Benefits of technology

[0019] (1) The present invention provides a high-power diesel engine pipe fitting air tightness testing device, which has a first clamping gap and a second clamping gap inside the intake unit and the sealing unit, respectively. When conducting the air tightness test of the pipe fitting, the operator can insert the pipe fitting at both ends of the pipeline to be tested into the two clamping gaps, thereby quickly completing the assembly of the device with the pipeline to be tested. Secondly, the device has an intake sealing gasket and a bearing sealing gasket inside the intake unit, and a first sealing gasket and a second sealing gasket inside the sealing unit. Therefore, when the pipe fitting is inserted into the clamping gap, it can achieve good sealing and compression, improving the accuracy of the air tightness test results. In addition, the device can also form a hemispherical structure for the intake sealing gasket by the cooperation of the shaped outer conical surface and the shaped inner conical surface. When the gas is introduced into the intake unit along the intake pipe, the hemispherical intake sealing gasket will expand and deform because the inner diameter of the first intake hole is smaller than the inner diameter of the intake pipe. This improves the adhesion between the intake sealing gasket and the pipe fitting, enhancing the sealing effect of the intake unit.
