Self-temperature control valve is a can without outside energy can be automatic temperature adjustment instrument, it applies to steam, hot water, hot oil for a variety of heat transfer medium conditions. Widely used in heating, air conditioning, domestic hot water temperature is automatically adjusted, and the temperature is automatically adjusted for special occasions, such as chemical, textile, pharmaceutical and other production processes. It is the use of liquid thermal expansion and incompressible liquid principle automatic adjustment. Expansion of the liquid temperature sensor inside the uniform, the control action to proportional control. When accused of medium temperature, temperature of liquid volume in the sensor with the expansion or contraction. When accused of medium temperature higher than the set value, the temperature of liquid expansion, pushing down the valve to close the valve, reducing the flow of heat medium; temperature controlled medium is less than the set value, the temperature of liquid contraction, the return spring pushes the valve core open, increasing the flow of heat medium. Simple self-acting thermostatic valve to facilitate us to better understanding of the products, most simple products are durable. Self-analysis thermostatic valve: temperature control valve water temperature below the set value; thermostatic valve water temperature is higher than the set value. 1. Initial temperature control valve water temperature below the set value the use of equipment or prolonged use again after the shutdown, please wait system cycle times can be raised to the required temperature. Such as the number of cycles the temperature does not rise always, check the following aspects: a heat source pressure or flow rate is too small. Note: One source of pressure or flow instability may cause temperature fluctuations. Trap heat exchanger unit is blocked or too much resistance, check the water or open water valve bypass valve. Self-temperature control valve stem due to heat or tamponade tight lock, so that the valve can not open, please use random wrench counterclockwise trimming bell tamponade or spring nut can be. Note: Stem locking reflected in the spring compression can not be reset. Self-check whether the thermostatic valve conduit and piping hot contacts, resulting in an additional temperature, make its separation. 2. The thermostatic valve water temperature is higher than the set value check Self-temperature control valve bypass shut-off valve is leaking or not closed. Self-temperature control valve water temperature is set too high, lower the water temperature by adjusting wrench. Observation of the stem is in the open state, rather than downward compression, then you need to check whether the catheter or bulb Lou Ye, such as leakage please change. Drain valve body, need to open the valve check valve port is stuck welding slag and other debris or scratches caused strictly off steam leakage. Line does not act to check the catheter is broken or cracked, resulting in the catheter or bulb liquid leaks. Good quality self-operated temperature control valve first durable, easy to repair glitches, manufacturers timely on-site service.
