Automatic changeover valve for chlorine gas system |
| abstract |
An automatic changeover diaphragm valve for chlorine gas service incorporates a loading spring on the atmospheric side of the diaphragm in order to provide a regulated positive pressure discharge. A latching mechanism for the valve employs spaced parallel rods which engage a V-groove on the loading spring spool to hold the valve in standby condition prior to release for changeover operation. The diaphragm includes a tetrafluorethylene web on the gas side and a chlorosulfonated web on the atmospheric side clamped at the outer peripheries. A sectored metal disk is used to abut against the chlorosulfonated web while the central portions of the two webs are in clamped disposition. |
