<p>The invention relates to construction. The technical result is an increase in the range of pipe components for shut-off and cleaning fittings, which components can be compactly arranged in a single housing to produce assemblies that perform the functions of shutting off pipes, carrying out filtration and regulating the pressure of a transported fluid. The valve comprises a housing with an inlet coupling pipe and an outlet coupling pipe disposed on opposite sides on the same axis, and with a filter chamber and a pressure reducer chamber disposed radially relative to the axis of the aforesaid pipes. The space in the housing cavity between the pipes is closed off by a separating partition. The filter chamber has an annular centering element which abuts one end of a filter element. A ball valve is mounted in the housing between the separating partition and the inlet coupling pipe. The pressure reducer chamber has a cylindrical cavity, the latter communicating with the cavity of the outlet pipe via an opening, and is closed by a cap. The stem of the pressure reducer has a piston part at one end and a pressure reducer disc secured to the other end, and is provided with an open axial seat which communicates with a radial opening in the stem. A gap exists between the stem and the cap, which gap communicates with the seat cavity.</p> |
