| Provided is a tandem cone valve capable of avoiding or reducing resistance on a valve switch caused by fluid pressure in a pipeline in the opening or closing stage. The cone valve includes valve rods, valve cores and a valve body. The valve cores include a first valve core and a second valve core. The first valve core and the second valve core are coaxially arranged in a valve core cavity. The outer walls of the valve cores are in the shape of cones; the first valve core and the second valve core are stacked one on the other, the first valve core is provided with a first valve core first flow hole and a first valve core second flow hole which penetrate through the inner wall and the outer wall of the first valve core, and the valve core cavity is provided with a valve core cavity flow hole corresponding to the first valve core first flow hole and the first valve core second flow hole. The cone valve is provided with the second valve core stacked coaxially on the base of the first valve core, and the second valve rod driving the second valve core to rotate is arranged in the first valve rod in a sleeved manner, thus the valve is simple and compact in structure; and the two levels of valve cores can each rotate to open/close the valve level by level, thus reducing momentary resistance when opening and closing a large cone valve. | ||||||

| A rotary valve capable of high flow rates, minimal pressure drop, and rapid actuation is presented. According to one aspect, the rotary valve is characterized by a unique pressure balancing system operating on the rotary spool of the valve to reduce side force caused by pressure at the flow ports. According to another aspect, the rotary valve is characterized by a unique internal shiftable blocking spool in response to a failure condition or a modulating signal. According to another aspect, a unique interface is provided for sealing a port of a rotary valve to an outer surface of a rotary spool. According to another aspect, the rotary valve is characterized by a unique interface provided for sealing a port to an outer surface of the rotary spool. According to another aspect, a rotary valve is characterized by a unique three-way three-or-more-position configuration. According to another aspect, a rotary valve is characterized by a unique four-port three-position configuration. | ||||||

| 138 | Liquid dispensing circuit | US13611163 | 2012-09-12 | US09474890B2 | 2016-10-25 | Shingo Koyama |
| A liquid dispensing circuit is provided with: a multi-way cock; a first line; a second line; a third line; a fourth line; a fifth line; and a casing which houses some of the above. When a cock in the multi-way cock is situated in a priming position, a distal opening in a second part of a first flow channel communicates with a first port, and a distal opening in a third part communicates with a second port; thus, the first port and the second port are in an open state wherein the ports are connected to each other via the first flow channel, whereas a third port, a fourth port, and a sixth port are in an open state wherein the ports are connected to one another via a second flow channel. | ||||||

| An automatic balancing valve is described provided with a valve body having at least one inlet channel and an outlet channel for a heat transfer fluid, wherein the flow regulation is carried out by a ball shutter having an axial through channel with axis perpendicular to the rotation axis of the ball. The ball valve has at least one radial channel aligned with the rotation axis of the ball and is connected to the axial through channel. The radial channel has an outlet port having a circular cross-section which hydraulically connects the axial through channel of the ball with the outlet channel of the valve. | ||||||

| A rotary valve adapted for use in utility scale fluidic systems improves over conventional valving schemes by affording reductions in weight, pressure drop, cost, and actuation time, as well as providing improvements in decompression performance, higher pressure capability, and longer operational life. One embodiment of a three way valve assembly utilizes electric actuation to adjust decompression in real time and facilitate port shaping. The valve assembly utilizes a pressure balanced rotor and seals to reduce actuation and bearing loads, as well as increase seal life. | ||||||
