Abstract

A kind of whorl spirotallic gasket, be made up of inner ring, outer shroud and seal element, inner ring and outer shroud are made by shaped-steel strip spiral winding, and ring is thick and internal-and external diameter is identical with common spirotallic gasket.Theory and practice proves: the inner ring of whorl spirotallic gasket and outer shroud can meet requirement of strength and play locates, strengthens the effects such as fixing, and process, get the raw materials ready conveniently, economize material and save time, cost is low.

Description

Whorl spirotallic gasket

Technical field

The utility model relates to a kind of whorl spirotallic gasket, is applied to the equipment of the departments such as oil, chemical industry, electric power, machinery, pharmacy and the field of sealing technology of pipeline connection.

Background technique

Spirotallic gasket is entwined together with non-metallic with W type or V-type shaped-steel strip, in order to reasons such as installing, transport and be safe, sometimes need to arrange metal inside and outside ring, its theory is constantly developing always, but about the theoretical research of spirotallic gasket still very imperfect.Spirotallic gasket application in practice becomes more and more extensive, especially accounts for more than 80% of all pads especially in the application of oil, chemical industry, power industry.

Because the inside and outside ring of spirotallic gasket is made by after the thick steel plate cutting of 2mm or 3mm, standard is various, material and specification are countless especially, and production technology is more loaded down with trivial details, need through multiple working procedures such as blanking, car, punching, dish, milling, kerve, chamfering, typewritings, this way cost of not only wasting time and energy in actual production is high, and causes steel and waste greatly, and even domestic have many spirotallic gasket manufacturing enterprises by the mode of outsourcing inside and outside ring to simplify production routine.

Summary of the invention

In order to overcome existing spirotallic gasket inside and outside ring processing time consuming, effort, Fei Cai, high in cost of production shortcomings, the utility model provides a kind of whorl spirotallic gasket.

The utility model is achieved by following technical proposals:

Whorl spirotallic gasket, roughly the same with structure with common spirotallic gasket working principle, be made up of inner ring, outer shroud, seal element, the making of seal element is identical with common spirotallic gasket, has inside and outside ring only not identical.Its inner ring and outer shroud are shaped-steel strip spiral winding and form, the making of shaped-steel strip is identical with the shaped-steel strip making method in seal element, the thickness of the inside and outside ring be wound in and internal-and external diameter consistent with the inside and outside ring of common spirotallic gasket, the two ends steel band of the inside and outside ring be wound in is fixed in by spot welding and is wound around on ring.When whorl spirotallic gasket works, its inner ring, outer shroud can play location equally, strengthen the effects such as fixing.

The beneficial effects of the utility model are, while meeting inside and outside ring function demand, conveniently can draw materials, process, thus time saving and energy saving, reduce costs, and save raw material.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further illustrated.

The common inner ring of 1-; 2-seal element; The common outer shroud of 3-; The inner ring that 4-shaped-steel strip spiral winding is made;

The outer shroud that 5-shaped-steel strip spiral winding is made

Embodiment

In Fig. 1 and Fig. 3 inner ring 1 and outer shroud 3 processing technology very complicated, through multiple working procedures such as blanking, car, punching, dish, milling, kerve, chamfering, typewritings, need waste time and energy, waste material many, processing cost is high; Inner ring 4 and outer shroud 5 in Fig. 2 and Fig. 4 form with shaped-steel strip coiling on special winding machine.Be wound around the processing of inner ring: can first process inner ring 4, spot welding is fixed; Be wound around the processing of outer shroud: on the basis of inner ring 4, process seal ring 2, then process outer shroud 5 on the basis of seal ring 2, spot welding is fixed.Wherein, the size being wound around inner ring 4 and being wound around outer shroud 5 respectively with inner ring in Fig. 11 and outer shroud 3 measure-alike, whole course of working technique is simple, draw materials conveniently, time saving and energy saving, cost is low, waste is few, and the whorl spirotallic gasket processed is identical with common spirotallic gasket effect.

Claims

1. whorl spirotallic gasket, is made up of inner ring, outer shroud and seal element, it is characterized in that: inner ring and outer shroud are made by shaped-steel strip spiral winding.

2. whorl spirotallic gasket according to claim 1, is characterized in that: inner ring is identical with corresponding common spirotallic gasket inside and outside ring with the shape and size of outer shroud.
