The existing metal hose pressure testing device has a single sealing mechanism at the connection of locomotive components, which is prone to water leakage and leads to inaccurate testing results.
The connection mechanism adopts a combination design including a mounting ring, flange, movable ring, fixed ring and bolts. By tightening the bolts, the position of the fixed ring is adjusted, which drives the movable ring to move, ensuring that the sealing gasket body fits tightly against the connection part and preventing water leakage.
This effectively avoids water leakage during the pressure test, improving the accuracy and reliability of the test.
