Working principle and purpose of the product:

Manual regulating valves and self-locking manual regulating valves are mainly used in urban centralized heating, regional heating, circulating water projects, thermal power plant pipelines, and refrigeration and air conditioning projects. They have the functions of cutoff, throttling, and flow regulation, and can replace throttling orifice plates. They are a type of throttling device that can change the aperture.

Product Structure Features:

① Improving heating supply: All branch lines and heating points that use manual regulating valves can adjust the flow according to the design conditions to achieve good temperature conditions. This type of regulating valve has better regulating performance than gate valves and globe valves, and it has approximate linear regulating performance. Therefore, the uneven heating and cooling phenomenon of various heating buildings has been effectively improved.

② Energy saving: Due to temperature and pressure imbalance in the thermal pipeline network, some branches have excessive flow, resulting in high temperatures in some buildings. Users have to open windows to achieve the goal of energy saving.

③ Improving the hydraulic conditions of the network management: The manual regulating valve can be controlled according to the rated flow rate, reducing the excessive flow of the network management and improving the degree of deterioration of the original water conditions to a certain extent.
