Flush Valve Handle Assembly Providing Dual Mode Operation

Номер: US20120005816A1
Автор: John R. Wilson
Принадлежит: Sloan Valve Co

A dual mode flush valve includes a handle assembly having a handle, a bushing and a plunger. The bushing has a sleeve with a passage therethrough for mounting the plunger for sliding and tilting. The passage is defined by first and second partially overlapping bores that coincide at the inner end of the sleeve and are spaced one above the other at the outer end of the sleeve. The bores define a horizontal plunger travel axis and an angled plunger travel axis. Depending on which direction the user actuates the handle the plunger will travel along one of these axes. Travel along the angled axis will lower the plunger tip, allowing earlier clearance of a relief valve and a reduced flow through the flush valve compared to actuation with the plunger travel along the horizontal axis.

The present disclosure belongs to the technical field of farm irrigation, and particularly relates to a novel pressureless irrigation device. The novel pressureless irrigation device of the present disclosure uniformly conveys irrigation water to crop plant root systems on the basis of a “connector” principle; and the size of a flow cross-section necessarily satisfies the extremely-low flowing speed requirement of “lossless conveyance” for the “connector” in a static pressure dominant operating state, thereby eliminating a problem of irrigator blockage which accompanies energy dissipation. Water enters the atmosphere via transpiration of crop plants, and a water supply water level control pool at a head portion is triggered to replenish the water. The water consumption and water replenishment are adaptive, and human intervention and additional energy are not required, thereby realizing low-cost and “fool-proof” automatic irrigation and true sense of uniform irrigation.

A shaft may extend from the float into a chamber, and as the float moves from the first position to the second position, fluid may enter a chamber and bias the float further upward. In some examples, the shaft is further configured to increasingly obstruct the flow of fluid in the channel as the float moves from the first position to the second position.
