Thermostatic valve selection and maintenance problems of common problems

In today's "emission reduction and water conservation," a serious problem, we are committed to creating energy-saving water-based thermostat thermostat crystallization research and development of thermostatic valve, the advantage is that other valves can not be comparable. Subsequently, the quality of information related to the thermostatic valve has also been the great concern of the majority of users, the following to you about the product selection and maintenance information! Selection of thermostatic valve reference as follows: 1, solar water heaters, the general selection of low-pressure device thermostatic valve series 2, the water quality requirements of more stringent stainless steel thermostat valve can be used 3, low temperature radiant floor heating, heating type 4, large and medium heat Water system (such as: hotels, guesthouses, bathhouses, baths, swimming pools, nursing homes, office buildings), the choice of large flow thermostatic valve series 5, when equipped with a shower head more, according to the pressure conditions when the relevant parameters, Specifications thermostatic valve, unlimited expansion of traffic. Thermostatic valve repair and solution: Question 1: the same outlet temperature and hot water (ie no cold water mixed) Solution: Check the thermostatic valve hot and cold water inlet is equipped with anti, adjust the hot and cold water inlet interface can be. Problem 2: The water temperature is obviously higher than the set temperature Solution: Check the water pressure is too low (should be greater than 0.5bar), or whether the chilled water pipe is abnormal; can raise the water pump outlet pressure or replace the head pump, clean Filter valves and pipe blockages. Problem 3: The water temperature is significantly lower than the set temperature Solution: Check the hot water pressure is too low (should be greater than 0.5bar), or cold water pipe is blocked abnormalities; can be raised by hot water pump outlet pressure or replacement of large head pump, clean Filter valves and pipe blockages. Problem 4: water temperature suddenly hot suddenly unstable solution: when the pressure changes, the water temperature will have a few seconds to adjust the normal; always unable to stabilize, if it is due to the frequent opening and closing of the pump caused by sudden pressure sudden change Can be installed in the pump or pressure tank outlet regulator valve, or to install water pump inverter to avoid sudden changes in pressure. Problem 5: Hot water does not turn off automatically within 8 seconds when cold water is switched off Solution: Check that the filter is installed as impurities entering the valve plug can affect the seal. (Note: hot water temperature must be above 50 ℃, in order to meet the security anti-scalding effect) Problem 6: the valve outlet and the inlet end of a larger pressure drop solution: (pressure drop within 0.3bar is normal) if the cold Hot water pressure is greater than 2bar, pressure drop greater than 0.5bar is an exception; the reason is that the actual water consumption exceeds the maximum flow rate set by the thermostat valve caused by the actual flow by multiple valves in parallel. Question 7: There is no water outlet valve Solution: Check hot and cold water supply pipe is abnormal, any one end can not be normal water supply will not work.
