Abstract
Abstract A regulating station valve which is adapted to provide the functions of four valves, namely, a strainer, a regulating valve, and two shut-off valves in a single structure. The valve comprises a valve body having a chamber therein and provided with an inlet passage and an outlet passage, a first annular seal around said outlet passage in said valve body chamber, rotatable ball or cylinder valve seated on said first annular seal and a second annular seal seated against said rotatable valve at a point diametrically opposite to said first annular seal, and means for normally biasing said second annular seal against said rotatable valve to hold said rotatable valve in position in said valve body. A strainer means is rotatably mounted in said valve body for turning said rotatable valve between an open position and a closed position. The rotatable valve is provided with a high pressure fluid inlet chamber which is divided from a low pressure fluid outlet chamber so that high pressure fluid flowing through said rotatable valve enters the inlet passage and passes through the inlet chamber in the rotatable valve and thence through the strainer and into the valve body chamber. The fluid then flows back into the outlet chamber in the rotatable valve and thence out of the rotatable valve and into said outlet passage. A regulating valve means is also provided to control the flow of fluid from the valve body chamber into the rotatable valve outlet chamber. The outer surfaces of the rotatable valve direct fluid flow and also function to allow flow or stop flow.
