    摘要: A constant pressure valve for an inflatable product is provided. The constant pressure valve comprises: a housing defining an airflow channel within. A first sealing seat is disposed in the airflow channel and a first through hole is formed in the first sealing seat. An inflation valve core comprises: a first actuating assembly and a first valve head. The first actuating assembly is configured to drive the first valve head to disengage from the first through hole, or to engage with the first through hole in a sealing manner. The constant pressure valve is switchable between an inflation state, in which the first valve head is disengaged from the first through hole, and the airflow channel is unblocked; and a cut-off state in which the first valve head is engaged with the first through hole in a sealing manner, and the airflow channel is blocked by the first valve head.

    摘要: A pressure operated fluid valve (10) having a configurable diaphragm arrangement (100) consisting of a flexible profile (110), a sealing portion (130) having a metallic insert (131) encapsulated in a natural or a synthetic rubber, the sealing portion (130) having a combination profile (140), a pressure management profile (150) on an inside curvilinear surface (114) of the flexible profile (110); a clear peripheral space (14) between an outer surface (113) of the clapo-diaphragm (100) and inner circumferential surface (24) of the main fluid flow chamber (20) is maintained to a non-zero value, during an open and close operation of the pressure operated fluid valve (10) throughout its life cycle; further comprises a secondary pressure management assembly (170) disposed between the first anchor (57) in the diaphragm cover (50) and the second anchor (137) in the configurable diaphragm arrangement (100).
