Patent number: 10302206Abstract: A fluid valve structure capable of outputting constant flow and constant pressure is provided. A control handle is adapted to control turning of a ball valve. The ball valve is formed with first, second and third openings. The openings are arranged at 90 degrees each other. The diameters of the first, second and third openings can be set according to the required flow and pressure. The fluid passes the first, second and third openings through an annular guide groove and guide holes of a water inflow connector, enabling the fluid gathered to the small diameter pipe portion to output constant flow and constant pressure. The user can observe the state of the fluid through glass windows provided on the small diameter pipe portion. The control handle controls the turning of the ball valve for the openings to be located in TEST, OFF, and DRAIN state, respectively.Type: GrantFiled: July 16, 2015Date of Patent: May 28, 2019Assignee: Y.S. VALVE MANUFACTURING CO., LTD.Inventor: Chi-Yuan Wang

Patent number: 8365766Abstract: An observation valve structure includes an inlet pipe joint. The inlet pipe joint has an outer threaded section at an inner end thereof, an annular guide groove in the inlet pipe joint, and guide holes at the inner end thereof. The annular guide groove communicates with the guide holes. The inlet pipe joint has a stop trough at the inner end thereof for insertion of an annular gasket. A holder is provided on top of the connector body. The holder has two threaded holes at two sides thereof close to the inlet end of the connector body. A plate is positioned on the holder by two screws which are screwed in the threaded holes. The plate has a top surface with characters which are perpendicular to each other, a position hole disposed close to the middle character, and two apertures disposed at an outer side of the other two characters for insertion of the two screws. The handle has an indication plate. The indication plate has a positioning bead hole for insertion of a positioning bead.Type: GrantFiled: December 22, 2010Date of Patent: February 5, 2013Assignee: Y. S.

Patent number: 8086278Abstract: The invention discloses a holding apparatus, which includes a fixed body, a carrying stand and a signal cable. The fixed body includes a ball joint, extending portion and a cable tunnel. The cable tunnel, disposed within the fixed body, is connected to a first opening of the ball joint. The carrying stand includes a casing, a pivot component and a transmitting interface. The ball joint is pivotally connected to the pivot component through a second opening of the casing. The signal cable, disposed through the cable tunnel of the ball joint, is electrically connected to the transmitting interface within the carrying stand. When the carrying stand rotates relative to the fixed body, a limiting portion of the pivot component is used for stopping the extending portion, so as to limit a rotating angle of the carrying stand.Type: GrantFiled: May 14, 2009Date of Patent: December 27, 2011Assignee: Quanta Computer Inc.Inventors: Chin-Chen Li, Chi-Yuan Wang

Patent number: 7688168Abstract: Linear actuators (also known as an inchworm actuator) including a magnetically actuatable shape memory alloy (SMA) are described. The linear actuators include a bar and an actuator assembly, configured to achieve a linear displacement of the actuator assembly relative to the bar. A hybrid magnetic trigger including an electromagnet and a permanent magnet is used to selectively attract the magnetically actuatable SMA toward the magnetic trigger. The motion of the magnetically actuatable SMA can be converted to a linear displacement. The magnetically actuatable SMA can be implemented using a SMA exhibiting both ferromagnetic and SMA properties, or by a ferromagnetic mass coupled with an SMA (i.e., a ferromagnetic SMA composite). Linear actuators including bars incorporating a ratchet mechanism, and featureless bars are described. A hydraulic system incorporating actuators including magnetically actuatable SMA membranes is also disclosed.Type: GrantFiled: September 8, 2005Date of Patent: March 30, 2010Assignee: University of WashingtonInventors: Minoru Taya, Victor Cheng, Harry Sugandi, Yuanchang Liang, Hsiuhung Chen, Chi-Yuan Wang
