Abstract
Corrugated diaphragm apparatus for improved cycle life of a diaphragm are described herein. One described example apparatus includes a valve body having an inlet and an outlet to allow fluid to flow therethrough, a backing plate disposed within a bonnet and coupled to the valve body, and first and second diaphragms. Each diaphragm has a corrugated profile and is in a stacked configuration. The diaphragms are operatively coupled to the backing plate and each of the diaphragms is clamped between the valve body and the bonnet proximate a peripheral edge of the diaphragm.
Claims20
An apparatus comprising:
- a valve body having an inlet and an outlet to allow fluid to flow therethrough;
- a backing plate disposed within a bonnet and coupled to the valve body;
- and
- first and second diaphragms, each having a corrugated profile and in a stacked configuration, the diaphragms operatively coupled to the backing plate, each of the diaphragms is clamped between the valve body and the bonnet proximate a peripheral edge of the diaphragm.
An apparatus comprising:
- a valve body having an inlet and an outlet allowing fluid to flow therethrough;
- a fluid chamber disposed within the valve body;
- a plurality of diaphragms in a stacked configuration adjacent to the fluid chamber, each diaphragm having a corrugated profile, wherein a first diaphragm is operatively coupled to a backing plate, and a second diaphragm is operatively coupled to a valve stem;
- and
- a bonnet containing the backing plate, wherein the diaphragms are clamped between the valve body and the bonnet.
An apparatus comprising:
- a plurality of diaphragms, each having a corrugated profile and in a stacked configuration, wherein the diaphragms are constrained at their peripheral edges and adjacent to a fluid chamber;
- and
- a valve stem operatively coupled to the diaphragms through central apertures of the diaphragms.
