Grain Pipe Valve Assembly

摘要

A grain pipe valve assembly maintains a desired level of flow restriction through a grain pipe. The assembly includes a valve couplable to a downspout. The valve is positionable proximate a lower end of the downspout. The valve has a swivel gate selectively extendable into the downspout wherein the swivel gate inhibits flow of grain through the downspout. A sensor is couplable to the downspout in spaced relationship to the valve towards the upper end of the downspout to detect when backflow of grain reaches a predetermined level in the downspout. The sensor is operationally coupled to the valve wherein the swivel gate is controlled and extended into the downspout to maintain backflow of grain to the predetermined level in the downspout.

1. A grain pipe valve assembly for attachment to a grain elevator and a downspout extending from the grain elevator, the assembly comprising:
a valve couplable to the downspout, said valve being positionable proximate a lower end of the downspout, said valve having a swivel gate selectively extendable into the downspout wherein the swivel gate inhibits flow of grain through the downspout; and a sensor couplable to a grain delivery path through the grain elevator and downspout, said sensor being positionable in spaced relationship to said valve towards the upper end of the downspout to detect when backflow of grain reaches a predetermined level relative to said lower end of said downspout, said sensor being operationally coupled to said valve wherein said swivel gate extends into the downspout to maintain backflow of grain to the predetermined level relative to the downspout.
