Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

Threaded hermetic bonded washer, comprise sealing inner ring 2, in the internal diameter of sealing inner ring 2, interval is provided with several delta seal lips 3, the line of delta seal lip is spiral line, adaptive with the track of screw thread, simultaneously delta seal lip is adaptive with screw thread form, the evenly spaced setting on the spiral line of formation of delta seal lip, and what the present invention can also be in the outside of seal ring adaptation arranges sealed outer ring 1.

Sealing inner ring 2, delta seal lip 3 can be integrally formed, and the material of sealing inner ring, delta seal lip can be the materials such as rubber.

When needs are used when of the present invention, screwed product is inserted in the present invention, rotation the present invention or product, the delta seal lip of seal ring and the screw-thread fit that needs the screw product of sealing, the present invention follows the screw advancement of the screw product that needs sealing to the position needing, the line of intermediate cam sealing lip of the present invention is exactly screw thread in fact, be equivalent to an internal thread and externally threaded cooperation, the present invention is just equivalent to a female product of tool, by the internal thread in the present invention, is not just continuous spiral line design.

Threaded hermetic bonded washer is for adjusting the seal washer of screw, nut, is the improvement of carrying out on the basis of original JB982-77 type (national Machinery Ministry standard).On the inner ring of existing product, increased the delta seal lip of three particular design, delta seal lip is to design according to the thread pitch of standard thread, delta seal lip can be fitted in screw thread closely, can play the effect of automatic core fixing, can better in screw thread, play seal action again, solve the drawback that existing product need to be processed locating slot and can not use seal ring in screw thread, can certainly produce supporting delta seal lip for off-gauge screw thread.

These are only the utility model embodiment's preferred embodiment; not in order to limit the utility model embodiment; all within the utility model embodiment's spirit and principle; any modification of doing, be equal to replacement, improvement etc., all should be included in the utility model embodiment's protection domain.
