1.Temperature control valve can not be used for a long time to do. Please close the valve before and after shutdown. When installed, the temperature control must be installed before the filter high mesh control valve.
2. Two temperature control valve must not be removed through the valve base for blind plate valve.
3. Should be based on the type of heat medium (steam / hot water), temperature and pressure parameters and use conditions (for heat exchanger type, open / closed system) considering chosen temperature control valve material, flow capacity and actuator shut off power.
4. When the use of temperature control valve for steam flow control, generally refers to the 98% dry degree of saturated steam. If the superheated steam, due to the change of the steam adiabatic index K and the fluid viscosity coefficient, the flow rate changes, the general need to re calculate the check.
5. Medium flow rate and the valve before and after the pressure into a square root. Too large pressure difference is not only noise, and cavitation effects on the body, affect the service life, light Mifengbuyan, severe cases may explode, causing casualties and major accidents.
6. Excellent temperature control curve is to achieve the effect of the guarantee. In addition to the special requirements of the rapid thermal system, should be as far as possible to ensure that the temperature control valve as a percentage or parabolic characteristics. Percentage: Q / Qmax = R (L / Lmax1) parabolic type: Q / Qmax = 1 / (1 + (R - 1) l / L Max] 2
7. Temperature control valve can not be used for direct water supply system, should be added cycle, if the heat exchanger is also need to add heat storage tank .
