Abstract
A valve is mountable in an opening in a gated pipe to control water flow, particularly in a cablegation system. A gasket is mountable in the irrigation pipe opening and a hollow leg of a T-shaped valve housing is inserted into the mounting member. The housing has a hollow, open-ended tubular portion which receives a hollow valve member. The valve member has an enlarged cap and a side opening alignable with the housing leg, the degree of alignment controlling the amount of flow. The valve member can also include a check valve.
Claims17
A valve assembly for regulating the flow of liquid through an opening in the side of a generally horizontal pipe comprising
- an elastomeric gasket insertable into the opening in the pipe, said gasket having flange portions inside and outside of the pipe in its mounted position and having a central generally rectangular opening alignable with the opening through the pipe for receiving a valve housing;
- a generally T-shaped valve housing having a hollow protruding portion shaped to extend into and engage said central opening in said gasket, the cross arms of said housing comprising a hollow, tubular member open at both ends,
- said gasket and housing being mountable in the pipe opening such that said arms of said housing lie in a generally vertical plane with one arm higher than the other;
- and
- a tubular, hollow valve member slidably received in the arms of said housing,
- said valve member having an enlarged portion at the higher end to limit the insertion of said member into said housing, and
- means defining a flow opening through the side wall thereof, said opening being axially spaced from said enlarged portion so as to lie in the same plane as said hollow protruding portion of said housing,
- said valve member being selectively rotatable to a plurality of positions in which the opening in said valve member is completely aligned, partially aligned and totally non-aligned with the hollow interior of said protruding portion and the opening in said pipe to thereby select the size of passage available for liquid flow.
A valve for regulating the flow of liquid through an opening in the side of a generally horizontal pipe comprising
- a mounting adapter insertable through the opening in the pipe, said adapter having a portion outside of the pipe in its mounted position for receiving a valve housing and having a central opening alignable with the opening through the pipe;
- a generally T-shaped valve housing having a hollow leg with means thereon for engaging said adapter, the cross arms of said housing comprising a hollow, tubular member open at both ends,
- said adapter and housing being mountable in the pipe opening such that said arms of said housing lie in a generally vertical plane with one arm higher than the other;
- and
- a tubular, hollow valve member slidably received in the arms of said housing,
- said valve member having an enlarged portion at the higher end to limit the insertion of said member into said housing, and
- means defining a flow opening through the side wall thereof, said opening being axially spaced from said enlarged portion so as to lie in the same plane as said hollow protruding portion of said leg,
- said valve member being selectively rotatable to a plurality of positions in which the opening in said valve member is completely aligned, partially aligned and totally non-aligned with said hollow leg and the opening in said pipe to thereby select the size of passage available for liquid flow.
