This also increases the working environment that the copper piston type pressure-reducing valve can adapt to, reduces the demand for various types of piston type pressure-reducing valves in various environments, reduces the complexity of the work of the staff during the installation work, and is conducive to the long-term use of the copper piston type pressure-reducing valve.

[0027] Furthermore, a lifting column 9 is fixedly connected to the top of the external block 7, and a clamping frame 10 is fixedly connected to the top of the lifting column 9 to ensure the stability of the pressure reducing valve when it is working.
