Abstract
The utility model relates to a spring type anti-loose composite seal washer, which belongs to the technical field of the manufacturing of seal components on machinery. The seal washer is mainly technically characterized in that an elastic seal washer is arranged on a ring-shaped seal washer concentric therewith, a spring washer concentric with the ring-shaped seal washer is fixedly arranged on the outer circle thereof, and the spring washer fixedly arranged on the outer circle of the ring-shaped seal washer adopts a ring-shaped body with the ends opened and staggered. The utility model having the advantages of simple structure, light weight, low manufacturing cost, long service life and convenient disassembly integrates the characteristics of a rubber seal washer, a metal seal washer and a spring washer; the excellent creep and relaxation resisting performances are good during use; and remarkable sealing effect is achieved. The utility model can be applied to various mechanical devices to realize the sealing and transport of liquids or gases.
Description
One, technical field
The utility model relates to the seal washer that uses when realizing liquid or gas seal and conveying on a kind of machinery in docking operation, the locking compound seal packing ring of specifically a kind of spring belongs to mechanically air locking manufacturing technology field.
Two, background technique
Have in the equipment manufacturing technology field of liquid or gas delivery at large-scale engineering machinery equipment, petroleum pipeline, transformer and various instrument and apparatus etc., in order to make mechanical internal cavity sealing effect better, prevent liquid or gas leak, usually be lined with different seal washer with folder between mechanical fitting axially docks at mechanical fitting, can make the mechanical connecting part place reach the internal cavity sealing, realize sealing and conveying liquid or gas.All need to seal butt joint during for example to petroleum pipeline and motor assembling, prevent that the joint poor sealing from causing gas leak of the oil leakage with gasket seal.Existing gasket seal adopts homogenous material mostly, as rubber seal, metal o-ring, spring sealed circle.After in use being squeezed, the rubber seal sealing material is easy to distortion, and distortion back elasticity variation.Particularly interface is the accessory on plane when sealing, and makes the seal ring deformed damaged and comes off with existing air locking is the easiest, thereby cause between the mechanical fitting poorly sealed.For this reason, people are provided with an annular groove to mechanical fitting one end that needs seal, and then seal ring are embedded in the groove of metalwork to dock then, can reach the seal action to metal device.Though this method can play the effect of sealing, process cutting to sealed metal device surface, like this with regard to invisible increase workload, increased the manufacture cost of machinery.Metal o-ring with have very high resistance to pressure though spring sealed circle is compared rubber seal because metallic alloy plasticity is relatively poor, be not easy to take place elastic strain, certain defective is arranged in machinery is close.
Three, model utility content
The purpose of this utility model be for the air locking that solves in the existing seal washer be the single structure material, rubber seal infinite place function, the easy extrusion damage of seal ring, seal degree is difficult to artificial support and holds, sealing effect is poor, though metal o-ring and spring washer have limit function, metal o-ring and spring washer flexibility are relatively poor, be difficult to after the distortion be returned to shape in the past, thereby propose a kind of new technological scheme.
For achieving the above object, the utility model solves the prior art defective can adopt following technological scheme:
The locking compound seal packing ring of a kind of spring, it is to be made of the ring packing packing ring, compoundly on the ring packing packing ring be provided with the elastic packing packing ring concentric, on the excircle of ring packing packing ring, be fixed with and ring packing packing ring concentric openings spring washer with the ring packing packing ring.
Circle being provided with concavo-convex rib in the ring packing packing ring, and the elastic packing packing ring is by concavo-convex rib and the ring packing packing ring is compound links together; The shape that is located at the spring washer on the ring packing packing ring excircle is the annular solid of a non-sealing and opening dislocation.
The advantage that the utility model is compared with prior art had is: simple in structure, easy to use, because ring-shaped rubber seal ring and metal o-ring, spring washer are combined, use have rubber gasket and metal packing washer intrinsic characteristics separately, add spring washer intrinsic characteristic, the sealing effect highly significant, dismounting is easily. and the creep resistant relaxation property is very good during use, and it is cheap for manufacturing cost, in light weight, long service life. on various mechanized equipments, can realize security seal and conveying to liquid or gas.
Four, description of drawings
Accompanying drawing 1 is a kind of example structure schematic representation of the utility model;
Accompanying drawing 2 is that the A-A of the utility model accompanying drawing 1 is to cross-sectional schematic.
Five, embodiment
Now with specific embodiment the utility model is described in further details in conjunction with the accompanying drawings:
The locking compound seal packing ring of a kind of spring, compoundly on ring packing packing ring 1 outer surface made from metallic material be provided with the elastic packing packing ring 2 concentric with ring packing packing ring 1, its material is a rubber, welding is fixed with the spring washer 3 concentric with ring packing packing ring 1 on the excircle of ring packing packing ring 1, its material is a metal, both ends open.The shape that is located at the spring washer 3 on ring packing packing ring 1 excircle is the annular solid of a non-tight and opening dislocation, and both two corresponding end mutual dislocation of spring washer 3 were provided with, and had elastic performance.
The utility model in use has the multiple performance of rubber seal, metal o-ring and spring washer, and it is very obvious to be used for the mechanical seal effect, can be widely used in the various engineering machinery.
