Figure 7-5.V-Notch Gas Feeder-typical installation, 3 to 200 lb/24 hr.
Figure 7-7 shows a typical chlorine piping
installation. A vacuum will pull on the diaphragm in
the gas pressure-regulating valve and open the inlet
valve. The entrance of chlorine will hold this vacuum
at a fairly constant value. Since the vacuum on the
upstream side of the V-notch variable orifice is
somewhat higher, the vacuum-regulating valve is
designed to maintain a constant drop across the V-
notch variable orifice. The V-notch plug can be
manually, electrically, or pneumatically operated.
NOTE: For variable vacuum operation, the
injector vacuum must be at least 10 inches of mercury.
OTHER TYPES OF CHLORINATORS
You may find other types of chlorinators at naval
activities. Among other types that may be at your
activity are the vacuum-type mechanical-diaphragm
chlorinator, the volumetric vacuum-type chlorinator,
the vacuum-type diaphragm-controlled chlorinator,
