To achieve the above object, the utility model proposes a kind of locking casing type sealing joint, including pipe fitting body, connection
Cutting ferrule, loose joint nut, the first gasket, the first sealing ring, wedge shaped baffle, elastic sealing gasket, the second gasket and the second sealing
Ring, the pipe fitting body in a tubular form, are equipped with the first gasket, first sealing ring is close to first in the pipe fitting body
The side wall of gasket, the elastic sealing gasket are located at the port of pipe fitting body, and the wedge shaped baffle is clipped in the first sealing ring
Between elastic sealing gasket, the elastic sealing gasket is engaged with the first gasket, the first sealing ring and wedge shaped baffle, the company
Card sleeve clamp is connect on the outer wall of pipe fitting body, the loose joint nut is connected with pipe fitting body.
Preferably, the side of the elastic sealing gasket is elastic zigzag structure, the side of the elastic sealing gasket is supported
On the side wall of the first gasket, the first sealing ring and wedge shaped baffle.
Preferably, the connecting sleeve includes the second gasket and the second sealing ring, second gasket is installed on
The junction of connecting sleeve and pipe fitting body, second sealing ring are close to the inner wall of connecting sleeve and the side of the second gasket
Wall.
Preferably, the side wall of the pipe fitting body is equipped with external screw thread, the external screw thread is engaged with loose joint nut.
The beneficial effects of the utility model：The utility model is by by pipe fitting body, connecting sleeve and loose joint nut knot
It is combined, it is easy for assemble or unload by assay optimization；It is close by the first gasket, the first sealing ring, wedge shaped baffle and elasticity
The tight fit of packing, has reached good sealing effect, extends the service life of pipe fitting, improves work efficiency.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
