1. Temperature control valve selection and application of common sense.
2. Should be based on the type of heat medium (steam / hot water), temperature, pressure parameters and the use of the operating conditions (heat exchanger type, open / closed system) considering the selection of the valve material, flow capacity and the actuator off force.
3. For the control of steam flow, generally refers to the saturation of 98% dry 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.
4. 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.
5. 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 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.
6. temperature control valve can not be used for a long time to do. Please close the valve before and after shutdown. When installed, must be installed before the filter mesh high temperature control valve.
7, two valve must not be removed through the valve base for blind plate valve.
8. Third the use of party production equipment and Sinopec valve products, should pay attention to meet the safety requirements.
9. The 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.
10. Domestic hot water conditions, please distinguish 24 hours hot water and timing of hot water supply conditions.
