Abstract
The utility model relates to a kind of novel glass end surfaces sealing gasket, comprises shim body, and the upper and lower surface of described shim body is densely covered with ring packing line, and described ring packing line is saw-tooth grooves.Shim body of the present utility model is covered with densely covered indented endless potted line, add sealing line length, and when glass tube end face and metal body flange fit sealing, by less clamping force, glass tube end face and sealing gasket just can be made to coincide seal, and the larger end face of diameter glass tube can be widely used in dock with the sealing of metal flange, simple and practical.
Description
Technical field
The utility model relates to mechanical seal field, is specifically related to a kind of novel glass end surfaces sealing gasket.
Background technique
In use, because of the impact of its factors such as material, structural design, usage safety performance has become the primary technical order of this product to gasket seal.For many years, because static seal point leaks, a lot of industrial accident occurs, some accidents cause tremendous economic to lose to country, cause casualties, and thus design, to produce a kind of novel sealing gasket particularly important.
In Chinese patent literature, publication number CN203413128U, title are a kind of mazy type multi sphere tooth metallic packing (see this application specification embodiment parts), disclose a kind of metallic packing that can use in fields such as petrochemical industry, power industry, war industry, mechanical industry, people's livelihood engineerings, comprise shim body, the upper and lower surface of described shim body is provided with the undulating seal lines surrounding ring-type of protrusion.The prior art every sealing lines length adds nearly 50% than the wall scroll length of sealing line of other sealing structure pad, improves reliability and the margin of safety of using state.Its deficiency existed is when docking with metal body flange seal at glass tube end face, because glass has the characteristic of good rigidly poor toughness, particularly when the glass tube end face that diameter is larger docks with metal body flange seal, need, by larger power, two planes just can be made to complete sealing docking.Fastening force is too large, Glass breadks easily, and fastening force is too little, and cannot realize the effect sealed, be the difficult problem in industry always.
Model utility content
The technical problem that the utility model solves is to provide a kind of novel glass end surfaces sealing gasket, when glass tube end face and metal body flange fit sealing, particularly when the glass tube end face that diameter is larger docks with metal body flange seal, by less clamping force, glass tube end face and sealing gasket just can be made to coincide and to seal.
In order to solve problems of the prior art, the utility model provides a kind of novel glass end surfaces sealing gasket, comprises shim body, and the upper and lower surface of described shim body is densely covered with ring packing line, and described ring packing line is saw-tooth grooves.
Compared with prior art, the utility model is on the sealing surface of sealing gasket, be covered with densely covered indented endless potted line, add sealing line length, when glass tube end face and metal body flange fit sealing, by less clamping force, glass tube end face and sealing gasket just can be made to coincide and to seal, and the larger end face of diameter glass tube can be widely used in dock with the sealing of metal flange, simple and practical.
Based on such scheme, the utility model also improves as follows:
Preferably, in described saw-tooth grooves, scribble sealer, be easier to coincideing of sealing gasket and seal face, further increase sealing effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
Fig. 2 is the A-A sectional drawing of Fig. 1
Specific embodiments
Providing preferred embodiment of the present utility model below, be described further the utility model, is not to restriction of the present utility model.
As shown in Figure 1, a kind of novel glass end surfaces sealing gasket, comprises shim body 1, and the upper and lower surface of described shim body 1 is densely covered with ring packing line, and described ring packing line is saw-tooth grooves 2.The utility model is on the sealing surface of sealing gasket, be covered with densely covered indented endless potted line, indented endless potted line adds sealing line length, jagged ring packing line top is more very thin, when glass tube end face and metal body flange fit sealing, by less clamping force, glass tube end face and sealing gasket just can be made to coincide and to seal, and the larger end face of diameter glass tube can be widely used in dock with the sealing of metal flange, simple and practical.Scribble sealer in described saw-tooth grooves 2, be easier to coincideing of sealing gasket and seal face, further increase sealing effect.Shim body 1 is made up of PTFE, stability of characteristics and high-and low-temperature resistance.
Claims (1)
1. a novel glass end surfaces sealing gasket, it is characterized in that: comprise the shim body be made up of PTFE, the upper and lower surface of described shim body is densely covered with ring packing line, and described ring packing line is saw-tooth grooves, scribbles sealer in described saw-tooth grooves.
