The invention discloses a pressure regulating valve, and relates to the technical field of pipeline control devices. The pressure regulating valve comprises a main body, wherein the inner side of themiddle of the top end of the main body is fixedly sleeved with a sealing film; the middle of the top end of the sealing film is fixedly provided with a sleeve shell; the middle of the top end of the sleeve shell is sleeved with a pipe clamping device in a threaded mode; and a regulating device is clamped on the inner side of the top of the pipe clamping device. According to the pressure regulatingvalve, the inner side of the bottom of a clamping block is movably sleeved with the outer side of the top of the pipe clamping device, so that the pressure regulating valve is effectively prevented from being broken caused by bearing the excessive torsion when regulating and expanding a device; the middle of the outer side of a regulating rod is sleeved with a lifting block in a threaded mode, and the lifting block, a first connecting rod, a second connecting rod, a fixing block and the regulating rod are matched, so that the convenience of the disassemblies and assemblies of the regulating device and the pipe clamping device is improved, and the problem that a hand wheel of an existing pressure regulating valve is inconvenient to disassemble and assemble is solved.
Description
technical field [0001] The invention relates to the technical field of pipeline control devices, in particular to a pressure regulating valve. Background technique [0002] The pressure regulating valve is an intuitive and simple flow regulating control device. The flow regulating valve used in the pipeline network can directly set the flow according to the design. The valve can automatically eliminate the residual pressure head of the pipeline and the pressure caused by the pressure fluctuation under the action of water. Flow deviation, no matter how the system pressure changes, the set flow rate remains unchanged. These functions of the pressure regulating valve make the flow adjustment of the pipe network complete at one time, effectively solving the hydraulic imbalance of the pipe network. [0003] After the existing pressure regulating valve is used for a long time, the spring force inside the valve will gradually attenuate, which affects the pressure regulating accurac...
