Abstract
Apparatus to interface with a corrugated profile are disclosed. An example apparatus for use with a fluid regulator includes an elastomeric ring having a corrugated profile that corresponds to a corrugated profile of a diaphragm of the fluid regulator. The elastomeric ring is to be positioned between a valve body and a bonnet of the fluid regulator to clamp the diaphragm between the valve body and the bonnet. The example apparatus includes a metallic ring positioned between the valve body and the bonnet to contact the elastomeric ring to support the elastomeric ring.
Claims16
An apparatus for use with a fluid regulator, the apparatus comprising:
- a diaphragm of the fluid regulator, the diaphragm having a first portion with a first corrugated profile, the diaphragm having a second portion extending diametrically away from the first portion and having a substantially flat surface;
- an elastomeric ring having a second corrugated profile that matably receives the first corrugated profile, the elastomeric ring to be positioned between a valve body and a bonnet of the fluid regulator;
- and a metallic ring having an annular groove that is defined by substantially perpendicular surfaces for receiving the elastomeric ring, the metallic ring for clamping the second portion of the diaphragm between the valve body and the bonnet.
An apparatus comprising:
- a diaphragm having a first corrugated profile and positioned between a valve body and a bonnet;
- and
- a washer to contact an outer circumferential portion of the diaphragm to position the diaphragm between the valve body and the bonnet, the washer positioned between the valve body and the bonnet and including:
- an elastomeric ring having a second corrugated profile that matably receives a first portion of the diaphragm having the first corrugated profile, and
- a metallic ring having an annular groove defined by substantially perpendicular surfaces, the annular groove to receive the elastomeric ring, the metallic ring having a surface that clamps a second portion of the diaphragm between the valve body and the bonnet, the second portion extending diametrically away from the first portion and having a substantially flat surface.
An apparatus comprising:
- means for sensing pressure within a fluid flow passageway, the means for sensing having a first corrugated profile and positioned between a valve body and a bonnet;
- and
- means for clamping the means for sensing between the valve body and the bonnet, the means for clamping positioned between the valve body and the bonnet and including:
- elastic means for engaging the means for sensing, the elastic means for engaging having a second corrugated profile that matably receives a first portion of the means for sensing having the first corrugated profile, and
- means for supporting the elastic means for engaging, the means for supporting having an annular groove defined by substantially perpendicular surfaces, the annular groove to receive the elastic means for engaging, the means for supporting to clamp a second portion of the means for sensing between the valve body and the bonnet, the second portion extending diametrically away from the first portion and having a substantially flat surface.
