Under the emission of 'water saving' a serious problem today, we are committed to build water-saving energy-saving hot water thermostat system research and development of crystallization thermostatic valve, its advantage is that other valve can match. Subsequently, the related features of thermostatic valve quality information also get the attention of users, the following to introduce the information relating to the product selection and maintenance! Thermostatic valve type selection reference is introduced as follows: 1, the solar energy water heater and low pressure device is generally selected thermostatic valve series 2, more strict with quality can use stainless steel thermostatic valve series 3, low temperature floor radiant heating, using the special 4, large and medium-sized hot water heating system ( Such as: hotel, hotel, bath, bath, swimming pool, nursing homes, office buildings) , can choose a big traffic thermostatic valve series 5, when equipped with shower head is large, the related parameters according to when the conditions of pressure, thermostatic valve with parallel multiple specifications, unlimited expansion of traffic. Thermostatic valve repair and solution: question 1: water and hot water temperature is the same, No cold water mixed with) Solution: check whether the temperature of hot and cold water inlet valve is installed backwards, adjust the import interface can be hot and cold water. Question 2: water temperature significantly higher than the set temperature solution: check whether the cold water pressure is too low ( Should be greater than zero. 5bar） , or abnormal cold water pipe is blocked; Can raise the cold water pump outlet pressure or replace big lift pump, clean up the filter valve and pipe blockage. Question 3: water temperature significantly lower than the setting temperature solution: check whether the water pressure is too low, Should be greater than zero. 5bar） , or abnormal cold water pipe is blocked; Can be adjustable heat pump outlet pressure or replace big head pumps, clean up the filter valve and pipe blockage. Question 4: hot and cold water temperature is not stable solution: when great changes have taken place when the pressure, there will be a few seconds to adjust the water temperature is normal. Always not stable, if it is because the pump pressure mutations caused by frequent opening and closing moment can add voltage regulator valve on the pump and pressure tank outlet end, or feed water pump with frequency converter to avoid pressure mutations. Question 5: when the cold water closed in 8 seconds no automatically turn off the hot water solution: check whether the filter installation, because impurities into the valve core will affect the sealing effect. ( Note: hot water temperature must be on the 50 ℃, can satisfy the security against the hot effect) Question 6: the valve outlet and inlet side pressure drop considerably solution: ( The pressure drop in 0. Within 3 bar is normal) If the hot and cold water pressure is greater than 2 bar, the pressure drop is greater than zero. The bar is the exception; Reason is that the actual water consumption is more than the thermostatic valve set maximum flow caused by multiple valve according to the actual flow in parallel. Question 7: the valve outlet without water solution: check whether there is hot and cold water supply line is unusual, any side can't normal water supply.
