The application of constant mix water valve
constant mix water valve applications: constant mix water valve company prompt floor heated hot water system should be running around 50 ℃; And the hot water in the radiator heated system generally at about 80 ℃, the radiator heated in the central heating system to heat the floor heated, article puts forward the solution; If after-glow floor heated reference this scheme can be deprived of boiler room or heat exchange station, reduce material and operation capability. Constant mix water valve company prompt general floor heated using aluminum pipe and PPR composite pipe, is can be resistant to high temperature above 80 ℃ water, but in terms of service life, other than water temperature 60 ℃ below operation life is long; Due to expansion and contraction coefficient of copper pipe joints and pipe, high temperature running, dripping joint subject will be very serious, affecting the floor heat of promotion, and easy to cause the user property losses.
we in practice is very good to solve the low temperature floor heated ( 55℃） Run topic, namely, by hot water on the floor before the water segregator equipped with hot and cold water mix water automatic thermostatic valve. Constant mix water valve has two cold water, hot water inlet interface and a mixed water outlet, the constant mix water valve, the mixed water outlet is equipped with a temperature sensor, using the physical characteristics of temperature-sensing component, promote body valve core is moving, seal or open cold, hot water inlet, in blocking the cold water at the same time open hot water, after the temperature control knob set a certain temperature, no matter how cold and hot water inlet temperature, pressure changes, the proportion of cold and hot water in outlet automatically change subsequently, so that the water temperature is constant, maintain its positive and negative value between plus or minus 2 ℃, temperature control knob can stipulate the scope temperature 35 ℃ to 65 ℃ within set arbitrary, constant mix water valve will automatically adjust the water temperature of setting. Note: water supply temperature of 60 ℃ - 80℃- 55 ℃ 95 ℃ water temperature for: mix of backwater pipe in the above check is to ensure that only extract geothermal water circulating pump, if the return water temperature is higher than the mixed water temperature, automatic constant temperature mix water valve automatically closed hot water into the water, the geothermal system automatic cycle, the return water temperature, after falling in a certain proportion in high temperature water, energy-saving effect is obvious.
hvac expansion valve motor operated valve is liked by everyone and is used in every household.
Many websites provide additional information on the topic of heat pump thermostat. One such site worth visiting is Edison HVAC Valves.
The major classifications of are ac compressor control valve, hvac expansion valve, ac compressor control valve and hvac expansion valve machines.
