3, for steam flow stem, general refers to the maximum limit of 98 one hundred percent dryness steam. 8, using the third party to produce composed of a set of facilities and Siemens products, should pay attention to safety requirements. Large Marine valve differential pressure more than initiation of noise, and initiation cavitation effect to the body, affect the use fixed number of year to survive, light person tightly closed lax, the person that weigh possible explosion, positions of the people and other major accident injury and death. For superheated steam, for steam adiabatic index change and fluid viscosity coefficient k cause flow change accordingly, general need to check again. 7, two-way valve can not cutting through tear down blind plate used as three way valve valve base. 5, good temperature control curve is the guarantee of successful implementation temperature control effect. Equal percentage: Q/Qmax = R ( L / Lmax - 1) Parabolic: Q/Qmax = 1 / [ 1 + ( R - 1) L / L马克斯) 26, temperature control valve can not use long time to do by the end of valve. 。 4, medium flow rate and pressure difference before and after the valve into a quadratic relationship. 9, temperature control valve can not be used for straight for the water system, must add cycle, if still need to add the number of heat exchanger heat storage tank. 10, living hot water conservancy engineering condition, 24 hours hot water and hot water supply condition regularly. Besides fast thermal system specifically asked, should try our best to ensure the valve for equal percentage or parabolic special properties. Prior to installation, temperature control Industrial Valves installation high mesh filter. Before and after the downtime, please close the valve manually. Q: application of common sense to answer: electric temperature control valve selection 1, the application of common sense 2, temperature control valve selection should be based on the heat medium category ( Steam/hot water) , temperature, pressure and the use of parameter conditions ( The type of heat exchanger, open/closed system) Comprehensive thinking problem valve material selection, flow experience and actuator shut off the power. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center. Three, it is very important when you use the occasion or the environment is more complex, would you please provide design drawings and detailed parameters, our engineers experts will concentrate on review and analysis for you.
