- Ordering Process
ZYC self-operated differential pressure balance valve is a kind of valve which uses the pressure change of the medium itself for self-control and keeps the constant pressure difference of the medium flowing through the controlled system. It is suitable for heating mode to adopt pressure difference control of double pipe system to ensure that the system is basically unchanged, reduce voice, balance resistance, eliminate heat network and hydraulic imbalance.
Characteristic
1. It is suitable for the water system which needs flow control, especially for the flow control of non-corrosive liquid medium such as heating and air conditioning.
2. Installed in the water system, the system flow can be automatically constant at the required set value by a single adjustment before operation.
3. It can automatically eliminate the hydraulic imbalance caused by various factors in the water system, maintain the flow required by users, and overcome the "uneven heat and cold".
4, improve the heating and air conditioning room temperature pass rate.
5. It can effectively overcome the bad operation mode of "large flow and small temperature difference", improve the energy efficiency of the system and realize economic operation.
Working principle
ZYC self-powered differential pressure balance valve uses differential pressure to adjust the valve opening, and makes use of the change of the pressure drop of the valve spool to compensate for the change of pipeline resistance, so that the pressure difference can be kept basically unchanged when the working condition changes. Its principle is that the pressure difference of the controlled system can be effectively controlled within a certain flow range.
