Abstract
The utility model relates to a combined washer used for sealing flanges and valves arranged on equipment in the industrial fields of chemical industry, pharmacy, petroleum, etc. The structure of the combined washer is that steel belts of a winding ring (3) are clamped and fixed between an inner ring (2) with an inner hole (1) and an outer ring (4), and steel belts are wrapped with two winding materials made of ceramic fibers and asbestos or graphite. The structure of the inner ring (2) and the outer ring (4) is that tooth-shaped grooves interlaced up and down arranged on both sides of a steel plate are combined with high-strength graphite paper (5) arranged on top of the teeth in distribution. The combined washer of the utility model has the advantages of high temperature resistance, high pressure resistance, corrosion resistance and long service life. In fact, one combined washer is equal to three ordinary winding washers.
Description
The utility model relates to industrial fields such as being applicable to oil, chemical industry, pharmacy, be used for flange, the valve seal of equipment, employed a kind of compound gasket.
At present, as the sealing of the flange on the chemical industry equipment, valve etc., employing be common spirotallic gasket.Inner and outer rings in its structure is a plane steel plate, twines ring and also has only a kind of material to twine.The pad of this structure, as equipment medium pressure jump, or sealing part is prominent is subjected to external force, or the factor such as careless of manual operation, and is very easily ineffective, and causes the leakage of equipment.Often change pad, not only waste of manpower, material resources have also influenced normally carrying out of producing.
In order to overcome the deficiency that common spirotallic gasket exists, the purpose of this utility model is to design a kind of novel compound gasket, to improve the usability of pad, prolongs the working life of pad, guarantees carrying out continuously of industrialized production.
To achieve these goals, design proposal of the present utility model is that prior art is improved it.On the doughnut-shaped steel plate face of interior ring, outer shroud, set up upper and lower staggered profile of tooth groove, and on tooth top, lay one deck high-strength graphite paper, to reach and the double seal effect of twining ring.The winding ring is to adopt ceramic fiber and asbestos or two kinds of materials of graphite to twine on the steel loop band, to improve high temperature resistant, the high pressure of pad, corrosion resistant performance, the working life of prolongation pad.
Compound gasket of the present utility model, aspect such as owing to twine the winding that ring has increased ceramic fiber, its usability is at high temperature resistant, high pressure, and is corrosion-resistant has improved three times than common spirotallic gasket.The high-strength graphite paper of laying on profile of tooth groove that interior ring and outer shroud are provided with and the tooth top is compound, shape or damage in case the winding environment-development changes, and interior ring, outer shroud can play the effect identical with twining ring, reach the effect of twice sealing.In fact a compound gasket is equivalent to three common spirotallic gaskets, thereby has prolonged the working life of compound gasket.Not not leaking of assurance equipment, this is for the continuity of industrialized production, and its meaning is very important.
For the structure to compound gasket of the present utility model has further understanding, details are as follows in conjunction with a specific embodiment of the present utility model:
Embodiment, compound gasket.
Accompanying drawing, be the structure cut-away view of compound gasket.
With reference to accompanying drawing, the structure of the utility model compound gasket has comprised among the figure the interior ring with endoporus (1) (2), clamping winding ring (3) in the middle of interior ring (2) and outer shroud (4) be by ring-like steel band outside Twine ceramic fibre, ceramic fibre outsourcing asbestos or graphite material are entwined. Ring (2) and outer shroud in it (4) structure is to be provided with upper and lower staggered profile of tooth groove on the thick doughnut-shaped steel plate two sides of 3.5mm With the compound formation of one deck high-strength graphite paper (5) of laying on the tooth top. Interior ring (2), outer shroud (4) Upper and lower profile of tooth is staggered, has guaranteed that the thickness of interior ring (2), outer shroud (4) is constant.
Claims (1)
1, a kind of compound gasket, it is made up of interior ring (2), winding ring (3), the outer shroud (4) of band endoporus (1), it is characterized in that the winding ring (3) of clamping in the middle of interior ring (2) and outer shroud (4) is to be entwined at ring steel belt outsourcing ceramic fiber, ceramic fiber outsourcing asbestos or graphite material, structure of ring (2) and outer shroud (4) is to be provided with the compound formation of high-strength graphite paper (5) of laying on upper and lower staggered profile of tooth groove and the tooth top on the doughnut-shaped steel plate two sides in it.
