Description

Technical Field

[0001] The utility model relates to the field of pressure reducing valves, in particular to a pressure reducing valve component which is convenient to install. Background Art

[0002] Pressure reducing valve, also known as safety valve, is a valve that adjusts the inlet pressure to the preset outlet pressure through its own mechanical components and automatically maintains a stable outlet pressure by relying on the energy of the medium itself. From the perspective of fluid mechanics, the pressure reducing valve is a throttling element with variable local resistance, that is, by changing the throttling area, the flow rate and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of pressure reduction.

[0003] At present, the pressure reducing valve is usually installed by connecting the flange to the pipeline. However, when the pressure reducing valve is connected to the pipeline through the flange, the flange of the pressure reducing valve and the flange of the pipeline need to be aligned and then locked and fixed by screws and nuts. This installation method is more troublesome and reduces the installation speed of the pressure reducing valve. Therefore, we propose a pressure reducing valve assembly that is easy to install to solve the above problem. Utility Model Content
