Fluid control valve, diaphragm sealing for a diaphragm valve and fluid valve body

摘要

Is a fluid control valve comprising a valve body configured with an input port extending to an input chamber, and an exit door extending from an exit chamber. The entrance and exit chambers are divided by a sealing bridge. A control chamber accommodates a flexible deformable sealing diaphragm between a sealing position in which it is enclosed tightly over the sealing bridge and seals a fluid flow path Q Which extends between the entrance and exit cameras,And an open position in which fluid flow along the flow path is allowed. An input path along the fluid flow path is larger than an output trajectory along it. An entrance radius of the sealing diaphragm is larger than an outgoing radius of the sealing diaphragm.
