Description
Technical field
The utility model relates to the fire-protection equipment field, is specifically related to a kind of novel decompression pressure regulator valve.
Background technique
The existing pressure regulator valve that generally uses, normally adopt such structural type: by valve body, import and outlet are arranged in the valve body, spool is housed in the valve body, spool is connected with valve rod in being loaded on valve body, spring is housed on the valve rod, spool is generally that hard material is made sphere or the end is the cylindrical of inclined-plane or curved surface, and the sealing configuration corresponding with spool is the potted line of valve body annular in the valve body, this pressure regulator valve pressure reduction instability and poor sealing, long-time back valve core and the spill sealing surface of using can produce distortion through multiple impact, influences voltage regulation result.
Summary of the invention
The purpose of this utility model provides the novel decompression pressure regulator valve that a kind of pressure regulation pressure reduction is stable, do not have leakage, long service life.
A kind of novel decompression pressure regulator valve, comprise valve body, be located at a side in the valve body spool, be located at the spool outside valve core case, be located at spool the inner push rod, act on balance spring between spool and the valve core case, be located at opposite side active base in the valve body, be located at active base interior adjusting screw, be located at the active base outside spring seat, act on the Regulation spring between active base and the spring seat, described valve body side is established valve gap.
