Self-reliance type temperature regulating characteristics of the working principle of pneumatic valve and its products

ZZT series self-reliance type temperature control pneumatic valve does not need external energy, and to automatically adjust the temperature of products. It is suitable for steam, hot water, hot oil, cooling water as medium of various technology and heat exchange and cooling conditions. Widely used in heating, air conditioning, hot water temperature automatic adjustment, as well as special conditions such as oil, chemical, textile, pharmaceutical, food and other production process.
self-reliance type pneumatic valve temperature regulation by using the principle of liquid heat expansion and incompressible automatic adjustment, the control effect of proportional control. Accused of medium temperature changes, the volume of thermal fluid inside the sensor with the expansion and contraction, accused of medium temperature is higher than the set value, thermal fluid expansion, promote shut down pneumatic valve, pneumatic valve core to reduce the flow of heat medium; Accused of medium temperature is lower than the set value, the thermal liquid contraction, reset spring push pneumatic valve core to open, to realize the balance control of temperature,
it's product features: without external energy sources such as electricity or compressed air, safe and reliable;
: thermal fluid expansion uniformity, proportion type adjustment control;
: controlled medium variety, can be applied to a variety of control occasions;
: high control precision, stable work, effective energy saving;
: balance type pneumatic valve body design, pneumatic valve can work under big pressure difference;
:
linear or equal percentage flow characteristics: temperature setting, simple operation, easy regulation;
: the equipment is small in size, light weight, installation is convenient;
: the balance of bellows components, adjust sensitive;
