Description

Piston type flow regulating valve Technical Field The utility model relates to the technical field of valve correlation, in particular to a piston type flow regulating valve. Background The flow regulating and pressure regulating valve is a first choice valve for realizing flow and pressure control, is now widely used as a mature product in large and medium cities around the country, has a market use experience of more than 10 years, is widely appreciated, has improved engineering requirements and enhanced automation degree along with the expansion of urban water supply areas in the future, and is also called a piston type multifunctional control valve because the flow regulating and pressure regulating valve has various control functions (such as a water level control function, a pressure reducing control function, a pressure maintaining and pressure releasing control function, a flow control function and the like) and can play roles of no cavitation, no turbulence, no vibration, sediment resistance and the like, so the flow regulating and pressure regulating valve is widely applied to the current large-scale water supply engineering; The existing flow regulating valve in the market is complex in structure, is inconvenient to perform flow regulating operation, and further reduces the practicability of the whole device. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a piston type flow regulating valve, which solves the problems in the background art. In order to achieve the above purpose, the utility model is realized by the following technical scheme: The utility model provides a piston type flow regulating valve, includes the valve body, the first connecting pipe has been set firmly in one side intercommunication of valve body, the opposite side intercommunication of valve body has set firmly the second connecting pipe, be provided with cooperation flow regulating mechanism between valve body and the first connecting pipe. Further, the matching flow regulating mechanism comprises a fixed ring, the fixed ring is fixedly arranged in the first connecting pipe, an adjusting cylinder is slidably arranged in the fixed ring, a plurality of rectangular flow regulating grooves are uniformly and penetratingly formed in the adjusting cylinder, a connecting plate is slidably arranged in each rectangular flow regulating groove, and each connecting plate is fixedly connected with the inner wall of the fixed ring; One side of the adjusting cylinder is communicated and fixedly provided with a piston head, the piston head is positioned in the first connecting pipe and slides along the inner wall of the first connecting pipe, the other side of the adjusting cylinder is fixedly provided with a fixed block, and an adjusting assembly is arranged between the fixed block and the valve body.
