Description

Special rust-proof non-return pressure relief valve for high-rise water pipe special for fire engine

Technical Field

The utility model relates to a pressure release valve, in particular to a special antirust non-return pressure release valve for a high-rise water pipe special for a fire engine, and belongs to the technical field of special non-return pressure release valves for high-rise water pipes.

Background

The check valve is a valve with a circular valve clack and acts by self weight and medium pressure to block the medium from flowing backwards. It belongs to the automatic valve category, also called check valve, reflux valve or isolation valve. The valve clack motion mode is divided into lifting type and swing type. The lift check valve is similar in structure to the stop valve and only lacks a valve rod that drives the valve flap. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). The valve is opened when the inlet pressure is greater than the sum of the weight of the flap and its flow resistance. Otherwise, the valve is closed when the medium flows backwards. Swing check valves have a flap that is tilted and can pivot, and operate on a similar principle to lift check valves.

When the check valve is used, because when butt joint check valve and outside connecting pipe, generally all adopt the bolt to lock fixedly, because the bolt is made for the metal, the rusty condition can appear in the long-term use bolt, leads to unable dismantlement, and simultaneously when using, the outside butt joint of flange does not carry out sealing process, can appear the condition of seepage in the clearance of butt joint when the flange live time is too long to influence the circulation of the inside water of pipeline.
