| 20110079743 | ROTARY VALVE - A rotary valve includes a main body provided with a valve chamber for receiving a plate valve, formed with an annular neck and bored with an intermediate hole extending downward to the valve chamber for positioning a valve rod, which is disposed in the intermediate hole when the main body is being shaped. A seal washer has its outer annular side provided with a serrated surface so that, when shaped, the main body can be combined with the serrated surface to let the seal washer covered by the inner annular wall of the valve chamber. The seal washer has an inner annular side symmetrically formed with an upper and a lower small flat surface respectively matching with an upper and a lower flat surface of the valve plate, having an upper and a lower side respectively bored with a hole for a valve rod to be inserted therein and fixed with the valve plate. | 04-07-2011 |
| 20100207049 | VALVE FOR LIQUIDS - A valve for liquids includes a main body and an upper lid or a connector. The main body is provided with a flow passage, an annular connecting circumference, an opening surrounded by the annular connecting circumference, and at least a metal ring integrally wrapped in the annular connecting circumference. The upper lid or the connector is provided with an annular connecting circumference having at least one metal ring integrally wrapped in it. Therefore, after having the main body combined with the upper lid or the connector, the valve can withstand comparatively large fluid pressure so as to prolong service life and be used to a wider application. | 08-19-2010 |
