The utility model is characterized in that a soft washer is pressed and inlaid on steps of an inner circular ring of the metal washer. The utility model has the advantages of good elasticity, pressure resistance, good sealing effect, etc. The utility model is suitable for oil pipelines of such industries as automobiles, diesel engines, petroleum, chemical engineering, etc. to use.
Description
The utility model relates to a kind of seal washer.
The seal washer that uses on the industry pipelines such as automobile, diesel engine, oil, chemical industry generally has three kinds on hard seal washer, soft seal packing ring and outer soft seal packing ring.Hard seal washer is made by metallic material, and rigidity is big, and not yielding, sealability is relatively poor; The soft seal packing ring is made by gummed paper, rubber or asbestos, and is broken easily during high pressure, can only be suitable for the occasion of lower pressure; Outer soft seal packing ring is bread one deck soft sealing material outside metal washer, and when pressure was higher, its outer soft seal was broken easily.
The purpose of this utility model is design a kind of good springiness, yielding, the not breakable closed combination seal packing ring of soft sealing material during pressurized.
The technical solution of the utility model comprises metal washer and soft washer, and annulus is shaped on a step in metal washer, and soft washer is inlaid on this step.
The advantage that closed combination seal packing ring of the present utility model is compared with existing seal washer is to adopt to press-fit a soft seal packing ring on the annular steps in metal washer, makes to the utlity model has good springiness, high pressure resistant, good airproof performance.
Fig. 1 is the utility model structure sectional view.
Now further describe embodiment of the present utility model in conjunction with the accompanying drawings.The utility model is made up of metal washer 1 and soft washer 2, and annulus is shaped on a step in the metal washer 1, and soft washer 2 is fitted on the step of metal washer 1.Metal washer 1 is made by copper, aluminium or stainless steel material, and soft washer 2 is made by gummed paper, rubber or asbestos material, and the radial seal effect is played in soft washer 2 inside radial expansions during use.
