As preferably, described spool top is also fixed with gland button, is provided with and holds out against spring between gland button and spool ring-shaped pressuring plate.Compression stroke between gland button and spool ring-shaped pressuring plate defines the position that spool stretches into valve body, ensures that apocenosis passage is through.Hold out against spring and spool is remained on idle position.
As preferably, described spool ring-shaped pressuring plate surrounding place side wall is provided with some air-vents.
As preferably, described spool is also provided with O-ring seal on the upside of bleed groove, and when spool stretches into valve body, O-ring seal seal buckle is located at valve body upper end open place.When spool is in discharge opeing state, O-ring seal can ensure that bleed path is closed.
As preferably, described valve body and shell supporting component spool ring-shaped pressuring plate outer ring week is also provided with for protecting and supporting.Shell supporting component, by the combination of multiple part, is formed valve body and spool ring-shaped pressuring plate and supports and protection.
This utility model valve core cavity and outer wall form discharge opeing and the bleed dual pathways, and two separate operations of passage, prevent body fluid channel and air duct string, eliminate the potential safety hazard that single channel spool brings; Spool can be extracted and carry out replacing cleaning, and spool can be used as expendable part, ensures the life-time service of valve body, reduces valve body replacement frequency.
