摘要

The invention relates to devices intended for collecting water from a pressurized water pipe network for extinguishing, namely to fire hydrants underground type.; Fire hydrant underground comprises a housing with disposed therein rod connected with the clutch spindle with the valve mounted thereon associated with the housing pipe configured with a valve seat; and a support ring, through which the spindle is omitted. Valve hydrant made of two parts interconnected by a threaded connection. Hydrant pipe is formed as a cylindrical tube with flanges. The inner surface of the nozzle is provided with a valve seat and the axially extending grooves adapted to contain the guide stops hydrant valve. The support ring is designed as a hydrant arranged concentrically and rigidly connected together by radial ribs of the outer ring and adapted for passing therethrough a spindle hydrant inner ring. Hydrant coupling is formed as a sleeve, which opening on the one hand adapted to accommodate the lower end portion of the rod hydrant, and on the other hand is adapted for receiving the upper end portion of the spindle hydrant.; What is new is that the valve, the sleeve, nozzle and the support ring is made of polyamide PA-6.; The technical result consists in reducing the weight and improving the corrosion resistance of the hydrant main assembly units, increasing reliability and reducing materials consumption hydrant.; 5 nz.p. f ly-6-yl.
