Abstract

PURPOSE: To prevent water hammering by providing a tapered projection which slowly squeezes flow rate before a valve is seated, in the primary valve body of a diaphragm valve body.
CONSTITUTION: Projections 4c and 4d with a tapered section 4e are provided at the primary valve body 4 of a diaphragm valve body 2 which is provided halfway in a passage. This permits the tapered section 4e to enter an exhaust port 1b before the diaphragm valve body 2 is seated and water flow to slowly be squeezed from the high flow rate to the low flow rate. As a result, water hammering can be prevented.
