Devices, systems, and methods for detecting properties of motion of at least one component of fluid exchange devices, such as, for example, a pressure exchange device or system.

Fluid exchange devices and related controls, systems, and methods

A downstream ball valve purging inlet directs purging fluid intentionally onto a downstream portion of the valve ball. The Coanda effect attaches some of the fluid to the ball's surface, so that it flows around the ball to an opposite side thereof, thereby purging the downstream valve cavity more efficiently than designs that avoid impacting the ball and depend on mixing to distribute the purging fluid onto the ball. The purging inlet can be downstream of the ball and directed at an acute angle, proximate the ball and directed perpendicular to the outlet axis, or some combination thereof. A central cavity purging drain can be connected with the purging inlet, so that the same fluid purges both the valve interior and the downstream cavity. Embodiments include a plurality of downstream purging inlets, which can have equal purging angles and can be equally spaced about the outlet axes.

Pressure exchange devices, systems, and related methods may include a tank, a piston, a valve device, and one or more sensors for monitoring a position of the piston in the tank.

Devices for exchanging properties, such as pressure, between at least two fluid streams and related methods may include pistons coupled to a valve stem. The valve stem and valve body may be configured to define a primary seal between the one or more pistons and the valve body and a secondary seal between the one or more pistons and the valve body.

Pressure exchange devices and related systems may include a valve device configured to selectively place a fluid at a first higher pressure in communication with another fluid at a lower pressure in order to pressurize the another fluid to a second higher pressure. Methods of exchanging pressure between at least two fluid streams may include a pressure exchanger having two low pressure inlets.
