Fig. 2 is the sectional view along A-A line in Fig. 1.
Embodiment
The utility model embodiment provides a kind of sealing gasket, has reduced the impact on the turbidity test of pipeline and equipment, has guaranteed the spatter property of fluent material.
For the purpose, technological scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment who obtains, and all belong to the scope of the utility model protection.
Please refer to accompanying drawing 1-2, the sealing gasket that the utility model embodiment provides comprises chip 1, the first non-metallic layer 2 and the second non-metallic layer 3, the first non-metallic layer 2 is compounded on the top end face of chip 1, the second non-metallic layer 3 is compounded on the bottom end face of chip 1, wherein, at least one of the first non-metallic layer 2 and the second non-metallic layer 3 is the politef layer.
Politef has good chemical stability, corrosion resistance, heat resistance and solvent resistance, its mechanical strength is higher, so, the politef layer is difficult for coming off under high temperature and high pressure environment, and, due to the chemical stability of politef, it also can not affect the spatter property of fluent material after coming off.
The first non-metallic layer 2 in the sealing gasket provided due to the utility model embodiment and at least one of the second non-metallic layer 3 are the politef layer, the politef layer is difficult for coming off, and then reduced coming off of sealing gasket, so above-mentioned sealing gasket has reduced the impact on the turbidity test of pipeline and equipment, guaranteed the spatter property of fluent material.
In addition, because the politef layer has stronger corrosion resistance and good chemical stability, the sealing gasket be comprised of the politef layer can be applicable to answer the pH value of chemical industry, pharmacy to require and the spatter property requirement.
When above-mentioned the first non-metallic layer 2 is the politef layer, the top end face of sealing gasket can not come off, and spatter property and corrosion resistance are better; When above-mentioned the second non-metallic layer 3 is the politef layer, the bottom end face of sealing gasket can not come off, and spatter property and corrosion resistance are better.The sealing gasket that the utility model provides can only be set to the politef layer by the first non-metallic layer 2, also can only the first non-metallic layer 2 be set to the politef layer.The present embodiment preferably all is set to the politef layer by the first non-metallic layer 2 and the second non-metallic layer 3.Now, top end face and the bottom end face of sealing gasket all can not come off, and the spatter property of two end faces and corrosion resistance are all better, have farthest improved spatter property and the corrosion resistance of whole sealing gasket, have guaranteed sealing, have improved working life simultaneously.
Preferably, in the sealing gasket that above-described embodiment provides, also be provided with a plurality of first projections that can be absorbed in the first non-metallic layer 2 on the top end face of chip 1.Chip 1 and non-metallic layer often are combined with each other by the mode of compacting, and the non-metallic layer of 1 pair of two end face of chip is played a supporting role.Compound tense, the first non-metallic layer 2 is overlayed on the top end face of chip 1, then with press machine, a plurality of the first projections on chip 1 are pressed in the first non-metallic layer 2, utilize the first projection that chip 1 is connected with the first non-metallic layer 2 more fastening, improved the join strength between chip 1 and the first non-metallic layer 2.
Further, also be provided with a plurality of second projections that can be absorbed in the second non-metallic layer 3 on the bottom end face of chip 1.Compound tense, the second non-metallic layer 3 is overlayed on the bottom end face of chip 1, then with press machine, a plurality of the second projections on chip 1 are pressed in the second non-metallic layer 3, utilize the second projection that chip 1 is connected with the second non-metallic layer 3 more fastening, improved the join strength between chip 1 and the second non-metallic layer 3.
In order further to improve the join strength of chip 1 and two non-metallic layers, also be provided with a plurality of attachment holes that are laminated into for politef on said chip 1.Because the plasticity of politef layer is better, in the process of pressing chip 1 and two non-metallic layers, part the first non-metallic layer 2 and part the second non-metallic layer 3 can be pressed in a plurality of attachment holes on chip 1, and chip 1 and two non-metallic layers are merged better, connect more firm.
In the present embodiment, the first projection and the second projection all are preferably to the flange of being gone out by punching.Because flange is thinner, be convenient to be pressed in the politef layer.Above-mentioned the first projection is obtained to the top punching by the bottom of chip 1, and the second projection is obtained to the bottom punching by the top of chip 1.Simultaneously, when by punching, obtaining the first projection and the second projection, also produce a plurality of attachment holes on chip 1, manufacturing process is simple.
