    摘要: The flow controller is capable of optionally controlling flow volume of controlled flow and reducing weight and a production cost. The flow controller comprises: a main body (2) having a first flow path (2a) and a second flow path (2b); a ring packing (10a) for sealing the flow paths (2a, 2b); a rod-shaped flow control member (12) tightly pierced through the ring packing (10a) and capable of moving with respect to the ring packing (10a), the flow control member (12) having a third flow path (12b); operation means (4) for moving the flow control member (12) so as to control the flow volume; a fourth flow (2h) path provided outside of the ring packing (10a); and a check valve (10b) prohibiting a fluid to flow from the second flow path (2b) to the first flow path (2a) via the fourth flow path (2h) and allowing the fluid to flow from the first flow path (2a) to the second flow path (2b) via the fourth flow path (2h).

    摘要: A valve (1) serves to reduce pressure, particularly in nozzling devices. Said valve (1) is situated in the branch line (4) behind a switching valve (3) and before a nozzle (5) and comprises a high-pressure piston (10) and a low-pressure piston (18), which are equipped with axial and radial bores (11, 12 and 19, 20, 21) and disposed so that their piston heads (13, 22) abut against one another. By using a valve (1) of the aforementioned type, the pressure of the water supplied to the nozzling device or to the dust control device can be reduced, for example, from 100 to 20 or 30 bar while a regulation of quantity simultaneously ensues.

    摘要: A technique facilitates regulation of flow through a flow control device to improve a well operation, such as a production operation. The technique utilizes a flow control device which has a valve positioned in a housing for movement between flow positions. The different flow positions allow different levels of flow through a primary flow port. At least one flow regulation element, e.g. a Venturi based flow regulation element, is used in a control line in communication with the valve to establish a differential pressure acting on the valve. The differential pressure is a function of fluid properties and is used to autonomously actuate the flow control device to an improved flow position.

    摘要: A water softener valve for controlling water flow to and from a water softener is disclosed that includes a cylindrical shaft extending from said inner surface of a piston chamber that fits into a pressure relief port when the piston is in the service position. The shaft clears the pressure relief port of any debris and closes the pressure relief port during the service cycle. The water softener valve also has a flow meter with at least two helically expanding vanes. A magnet on of the vanes trips a sensor as the turbine rotates, thereby providing means for calculating the flow of water through the valve. The valve also has a flow control button located at an inlet of the valve rather than at the drain, preventing the obstruction of the water flow by regeneration sediment of the tank at the drain. The valve also contains an internal piston port for permitting the free flow of water through the valve during a change in softener cycles.
