Abstract
The utility model discloses a compound flange washer of pipeline connecting fittings. A corrosion resistant forked coating sheet is adopted by the compound flange washer of pipeline connecting fittings. A lining spacing sheet is coated and protected by the corrosion resistant forked coating sheet. The dominance of the strong corrosion resistant performance of the corrosion resistant forked coating sheet is used. The compound flange washer of pipeline connecting fittings is applied, and the compound flange washer of pipeline connecting fittings has the advantages of close seal, corrosion resistance, no leakage, etc. The compound flange washer of pipeline connecting fittings has simple structure and easy fabrication. The compound flange washer of pipeline connecting fittings is an ideal pipeline installation fitting.
Description
The utility model relates to the accessory of piping erection, especially a kind of composite flange packing ring, and it is applied to pipeline enclosure and connects sealing joints.
Connection between traditional various pipes generally all adopts asbestos flange packing ring or rubber flange packing ring as seal connector.The decay resistance of this flange packing ring is relatively poor, and its intensity is not high yet.Long-term its pad that uses is easily aging, and hardening, becomes fragile, and then breaks, and loses sealing function, thereby causes the run, drip, leak of pipeline.The working life of this flange packing ring is shorter, and the cycle of changing flange is also just frequent, and this has just strengthened the labor intensity of maintenance work, more seriously causes the loss waste of material in the pipeline, and economic loss is great, has also polluted environment.
The purpose of this utility model is the rapid wear defective that will overcome the piping flange packing ring, designs a kind of not only corrosion-resistant but also the composite flange packing ring of certain intensity, high temperature high voltage resistant is arranged.
Task of the present utility model is that following technological scheme realizes: developed a kind of composite flange packing ring.This packing ring as the liner pad, outside this circular liner pad, is set up the fork-shaped bag sheet of being made by resistant material with original circular flange packing ring.The cross section of this bag sheet is V-shaped.The diameter on the inner ring edge, fork top of bag sheet is less than the internal diameter of circular liner pad, so that the fork top inner ring of bag sheet can be placed in the internal diameter mouth of liner pad.Pitch top inner ring along to extraradial two circular bag sheets by this like this, just can wrap on the two circle faces up and down of liner pad.When using this composite flange packing ring, fork-shaped bag sheet is inserted and put the composite flange pad that wraps the liner pad, place two nozzle flange places, fastening corresponding bolt, two fork-shaped bag sheets clamp the liner pad and are sealed up for safekeeping at flange connections.Because the decay resistance of fork-shaped bag sheet is high and liner pad combined strength bination increases, and has formed corrosion-resistant, high temperature high voltage resistant, has the composite flange packing ring of certain intensity.This packing ring long service life has also just prolonged operation period of pipeline and equipment, has alleviated employee's maintenance labor intensity.This flange packing ring has wide use prospect.
Corrosion resistant fork-shaped bag sheet has been protected the liner pad.It is crucial that the material of this bag sheet is selected: generally can select polytetrafluoroethylmaterial material for use, also can select polyurethane material for use, also can select anti-corrosion rubber material for use.
The optional asbestos washer of using of the liner pad of this composite flange packing ring, the also optional engineering plastics pad of using is as the liner pad with certain intensity.
The embodiment of this composite flange of accompanying drawings packing ring: the composite flange packing ring of making is the cotton flange packing ring of teflon lining stone.As shown in the figure: Fig. 1 is the plan view of composite flange packing ring.Fork-shaped bag sheet 1 is made for polytetrafluoroethylmaterial material among Fig. 1, and fork top inner ring is the circles that compile of two circular bag sheets 1 along 3.Fig. 2 is the A-A sectional view of composite flange packing ring.The fork-shaped bag sheet 1 that teflon matter is arranged among Fig. 2 is pitched the top inner ring along 3, the liner pad 2 of the asbestos washer matter that fork-shaped bag sheet 1 is wrapped up.This kind flange packing ring is applied to the chemical plant pipeline and connects, and uses nearly 1 year, does not occur any run, drip, leak phenomenon yet, and using effect is good.
Claims (3)
1, a kind of composite flange packing ring, outside its circular liner pad (2), be provided with and it is characterized by: the fork-shaped bag sheet of making by resistant material (1), the cross section of this bag sheet (1) is V-shaped, the diameter on fork inner ring edge, top, its (1) (3) is wrapped on the two circle faces up and down of liner pad (2) to extraradial two circular fork-shaped bag sheets (1) along (3) by this fork top inner ring less than the internal diameter of circular liner pad (2).
2, according to the described composite flange packing ring of claim 1, it is characterized in that: the fork-shaped bag sheet (1) that described resistant material is made, its material can be selected polytetrafluoroethylmaterial material for use, also can select polyurethane material for use, also can select anti-corrosion rubber material for use.
3, according to the described composite flange packing ring of claim 1, it is characterized in that: described liner pad (2), its material can be selected asbestos washer for use, the also optional engineering plastics pad of using.
