Split type valve cage facilitating dismounting and mounting of sealing ring

Abstract

The utility model relates to fluid control device technical field, specifically disclose a split type valve cage convenient to dismount sealing ring, including valve body, it according to structure is divided into one liquid inlet fluid channel, one liquid outlet fluid channel and be used for making the valve core mounting hole of liquid outlet fluid channel and liquid inlet fluid channel intercommunication, the valve core subassembly then is assembled in valve core mounting hole to control the opening and closure of liquid outlet fluid channel and liquid inlet fluid channel, one port section is fixedly installed with the balance cylinder in the same plane with it respectively in valve core mounting hole, one adjusting valve cage in the distribution of liquid inlet fluid channel and liquid outlet fluid channel junction and a sealing ring base in the distribution of bottom part. The utility model discloses the convenience of sealing ring dismounting through split type design, improves valve cage sealing reliability with radial-axial bidirectional sealing, and does not need to dismount valve body or destroy welding structure when maintaining.
