20150144822 | Diaphragm Valve - A diaphragm valve includes a valve body, a diaphragm, a bonnet, an operation mechanism, and a fixing mechanism. The fixing mechanism includes a clamping member for integrally sandwiching and fixing, from both right and left sides, circumferential edges of both the bonnet and the valve body. A circular pressing member for pressing a circumferential edge of the diaphragm from above is interposed between the diaphragm and the bonnet and has convex portions and concave portions. The convex portions fit into notches provided at the circumferential edge of the diaphragm or the valve body, and the concave portions are fitted by protrusions provided at the circumferential edge of the diaphragm or the valve body. | 05-28-2015 |
20140084198 | Ball Valve - Provided is a ball valve which may be manually opened and closed with ease by reducing handle torque and can securely prevent leakage. The present invention relates to a ball valve, comprising a valve body which has a fluid inlet passage, fluid outlet passage, and a communicating part provided between these passages, a ball which has a fluid communication passage and preferably is arranged on the communicating part of the valve body to be able to rotate about a reference axis, a substantially cylindrical ball seat which preferably has a desired opening part on its peripheral wall and is arranged between said ball and said valve body, a ball seat pressing part arranged inside said valve body so as to be adjacent to said ball seat, and a presser screw arranged to be screwed to fit in the inner periphery of said valve body. The ball valve preferably performs communication and interception between the fluid inlet passage and the fluid outlet passage by the rotation of the ball about the reference axis. The presser screw preferably presses the ball seat pressing part by adjustment of its tightening force and presses the ball seat pressing part without contacting the packing. | 03-27-2014 |
20100050928 | JIG FOR SELECTING VALVE PART NUMBER OR JOINT PART NUMBER - A jig for selecting a valve part number or a joint part number represented by a combination of selected symbols representing respective selected conditions required for selecting a valve or a joint comprising: a substantially rectangular base plate defining an inner space, and a plurality of linear sliding gauge laterally arranged in the inner space to slide in a longitudinal direction of the base plate, the sliding gauge comprising a condition description area including a plurality of conditions thereon from which the selected condition is determined, and a symbol description area including a plurality of symbols thereon, both the conditions and the symbols arranged in a sliding direction of the sliding gauge, a plurality of condition selecting windows laterally arranged on a top of the base plate, each condition selecting window configured to expose one of the selected conditions, a plurality of symbol selecting windows laterally arranged on the top of the base plate longitudinally apart from the condition selecting windows, respectively, each symbol selecting window configured to one of the selected symbols, wherein a distance between both windows is equivalent to a fixed distance between each of the symbols in the symbol description area and its corresponding condition in the condition description area. | 03-04-2010 |
