Top-loaded axial flow pressure regulator

Abstract

The present invention relates to a top-mounted axial-flow pressure regulator. It mainly includes sheath component, valve jacket, pressure-regulating valve port, valve core, valve rod, pressure regulator valve body, valve port reset spring, cut-off valve controller and sealing element, in which the sheath component is separated from valve jacket, said sheath component is positioned in the top portion of pressure regulator valve body, the valve jacket is positioned in the pressure regulator valve body interior, sand valve jacket is divided into front valve jacket and rear valve jacket, the inlet end of pressure regulator valve body is equipped with a sleeve, in the pressure regulator valve body interior a cut-off valve port and a cut-off valve spring are set, the cut-off valve port is connected with cut-off valve controller; and the valve rod is locked by means of removable component extended to the exterior of pressure-regulator valve body.

Description

Technical field [0001] The invention relates to an axial flow type pressure regulator, and in particular to a top-mounted axial flow type pressure regulator. Background technique [0002] The membrane component of the current axial flow regulator is coaxially fixed on the valve sleeve. When the internal parts of the regulator body are maintained, the entire valve body must be disassembled from the installed pipeline, which is not only a lot of work , And will affect the sealing effect of the pipeline system. In addition, the current axial flow regulator cannot be equipped with an integrated overpressure cut-off device, but an independent cut-off device must be installed at the inlet end, which is not only costly, but also the size of the pipeline system. At present, domestic axial flow regulators are mainly imported from abroad, such as the FL-BP type of Tartarini company in Italy, the 310A type of Fisher company in the United States and the 730 type of RMG company in Germany.
