Abstract

The utility model relates to a washer used for a glass pipeline and equipment. The washer used for a glass pipeline and equipment is a layer-shaped structure which is composed of the skeleton of a glass fiber cloth, and rubber which is used as agglutinant. The washer used for a glass pipeline and equipment has high temperature resistance, corrosion resistance, and good sealing performance.

Description

The packing ring that a kind of glass pipe and equipment are used

The utility model relates to a kind of clamping washer, particularly is applicable to the clamping washer that glass pipe and equipment use.

In the glass pipe connection procedure, for vitreous humor is broken, to between flange and pipe-line equipment, use flexible gaskets, flange and a vitreous humor isolation and a buffer function, the tradition clamping washer is under the condition of high temperature, rubber is easy to soften, cause the flange fastening force to descend, seal point is revealed, this rubber ring is under the situation that etchant gas exists, meeting is aging rapidly, contraction, causes the flange fastening force to descend equally, and the rubber of employing various material all can run into the problem of non-refractory and anticorrosive power difference and can't solve.

The purpose of this utility model is to propose high temperature resistant, the anticorrosive clamping washer that novel glass fiber cloth that a kind of glass pipe and equipment uses is done skeleton.

Model utility is achieved in that the packing ring that a kind of glass pipe and equipment are used, and it is characterized in that: packing ring is by the skeleton of coloured glaze fibre cloth 2 and make the stratiform structure that the rubber 1 of adhesive is formed.The stratiform structure that packing ring is made up of 6-30 layer coloured glaze fibre cloth framework layer 2 and rubber bond layer 1.

The utility model is done skeleton with glass fiber cloth, makees adhesive with rubber, does not at high temperature shrink also anticorrosive owing to make the glass fiber cloth of skeleton, both made at high temperature, under the corrosion situation, the flange fastening force can obviously not descend yet, thereby keeps the seal point sealing can not cause leakage.

The A-A cross-sectional view of Fig. 2: Fig. 1

Now further narrate structure of the present utility model in conjunction with the accompanying drawings:

Referring to Fig. 1-2: by rubber 1 and glass fiber cloth 2, the bonding formation packing ring of multilayer as skeleton, forms 6-30 shape structure layer by layer with rubber 1 as tackiness agent with glass fiber cloth 2.

Claims

1, the packing ring used of a kind of glass pipe and equipment is characterized in that: packing ring is by the skeleton of coloured glaze fibre cloth (2) and make the stratiform structure that the rubber (1) of adhesive is formed.

2, the packing ring used of glass pipe according to claim 1 and equipment is characterized in that: the stratiform structure that packing ring is made up of 6-30 layer coloured glaze fibre cloth framework layer (2) and rubber bond layer (1).
