Embodiment Construction
[0013] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment includes a flange 1 and a joint body 2. The sealing edge of the joint body 2 is pressed against the flange 1 with a metal taper 3, and the flange 1 is equipped with a connecting screw 4; the metal taper 3 is bidirectional. tapered surface.
[0014] As shown in the figure: the metal cone gasket 3 is designed as a two-way cone surface, and the sealing edge of the cone surface and the joint body 2 is pressed against the flange plate 1, and the metal seal can be realized by continuously tightening the connecting screw 4. When oil leakage occurs, the oil leakage phenomenon can be eliminated by tightening the connecting screw 4 again.
[0015] This product connects the flange plate 1 by the connecting screw 4, and it is enough to press the joint body 2 and the metal cone washer 3. In particular, the coaxiality between the metal cone washer 3 and the joint body 2 must be strictly r...
