摘要

An irrigation valve has a valve body with an inlet passage, an outlet passage, a valve seat intermediate the inlet passage and the outlet passage and a control chamber exit or bypass passage terminating in a surface that defines a portion of the outlet passage, the valve body including at least one of a recess and a rib for hindering clogging of the bypass passage. Related methods for hindering clogging of the control chamber or exit bypass passage are also disclosed.

1. A clog resistant valve body comprising:
an inlet passage; an outlet passage having a longitudinal axis and a stop positioned therein for ceasing forward progress of a pipe inserted into the outlet passage, the stop defining at least one recess; a valve seat intermediate the inlet passage and outlet passage; a bypass passage positioned generally transverse to the longitudinal axis of the outlet passage and terminating at one end proximate the at least one recess so that the at least one recess helps prevent adhesive from clogging the bypass passage; wherein the stop defines a flat wall extending from an inner surface of the valve body and having a downstream face that faces a downstream opening of the outlet passage, the stop together with the inner surface defining the outlet passage and a recess forming a depression in the downstream face of the stop and extending upstream therefrom to surround the bypass passage on at least three sides.
