Pipe insulator for water piping - has guide rings comprising slit plastic slide rings located in annular grooves of pipe guide cylinder

摘要

The slide rings are made from polytetrafluoroethylene preferably with an addition of bronze. The ends of the slide ring positioned either side of the slit overlap one another in the axial direction. The individual slits of the rings are circumferentially displaced relative to one another. The annular grooves in the pipe guide cylinder have a conical groove base whereby the smaller internal diameter of the groove lies in a direction towards the discharge pipe. The disconnection point between inlet pipe and outlet pipe is covered by a transparent protective cap. The valve body is acted upon by a compression spring tending to retain it in the closed position.
