This product is widely used in various types of heat exchange equipment such as domestic hot water, heating, bathhouses, central air conditioning, etc
Chemical, textile, printing and dyeing, pharmaceutical, shipbuilding, hotel, hospitality, and school industries. The applicable medium can be steam
High temperature water, hot oil, cooling water, chilled water, etc.
1, ZZWP temperature control valve
Control principle
Temperature sensitive liquids experience expansion and contraction due to temperature changes. Temperature increase
When the temperature sensing liquid expands, it drives the actuator to move and adjust the valve
Small body size reduces the flow rate of heat medium; On the contrary, when the temperature decreases, the temperature sensing liquid
Shrink the body, restore the spring to push the regulating valve body in reverse, and open the valve
Gate, increase the flow rate of the heat medium to achieve stable secondary effluent temperature at the set point
Within a designated range.
Product Features
Hydraulic drive, no need for external energy such as electricity or compressed vacuum, safe and reliable;
Make the temperature sensing liquid expand evenly, with proportional adjustment control;
There are many types of controllable media that can be applied to various control scenarios;
High precision control, stable operation, and effective energy conservation;
The balanced valve body design enables the valve to operate under greater pressure differentials;
Golden thread or equal percentage flow characteristics;
The temperature setting operation is simple and convenient for users to adjust;
The device is small in size, light in weight, and very easy to install.
2, ZZW (L) cooling valve
working principle
Self operated cooling regulating valve is regulated based on the principle of thermal expansion of temperature sensing liquid, contraction when cooled, and incompressibility of liquid. The working principle diagram illustrates its working process; Insert the temperature sensor into the medium that needs to be controlled for temperature. When the temperature of the medium increases, the temperature sensing liquid expands, pushing the valve disc downward and the valve tends to open, thereby increasing the flow rate of the refrigerant medium; On the contrary, when the temperature of the medium is lower than the set temperature, the temperature sensing liquid contracts, and the reset spring pushes the valve disc to close, reducing the flow rate of the refrigerant medium and causing the temperature of the controlled medium to tend to rise. Cycle back and forth, so that the temperature value of the controlled medium is always maintained within the allowable range of the set temperature value
Within the scope.
