Five, installation matters:

Installation, use and maintenance

(1) before installation, the pipeline should be strictly polluted, and the welding slag and other sundries should be removed, otherwise the valve will be seriously damaged.

(2) the temperature regulating valve should be installed vertically on the horizontal pipe, and the flow direction of the medium should be consistent with the arrow pointing on the valve body.

(3) in order to make the automatic control system or maintenance valve can continue to run, the bypass valve should be installed. The filter must be installed before the valve, the pressure gauge, and the thermometer installed near the sensor, which is convenient for on-site monitoring and temperature setting. See the picture below:

 

(4) the sensor must be immersed in the controlled medium and installed in horizontal or inclined upward direction.

 

(1) before installation, check whether the parts of the machine are defective or loose. The pipeline should be cleaned, and the flow direction of the medium should be consistent with the arrow pointing on the valve body.

(2) as far as possible to install in the vibration and small impact of the site, the valve weight is larger, there should be fixed support frame. The installation site should take into account easy operation and maintenance.

(3) the bypass manual valve should be set to keep the automatic control system out of order or to operate continuously when the valve is repaired. When the manual valve is checked and used, the stop valve should be closed before and after the valve is closed.

(4) all the packages are immersed in the modulated medium and installed horizontally or obliquely upward

(5) the bending radius of the capillary should not be less than 75mm, placed in the natural state, strictly prohibited folding or twisting.

(6) in order to facilitate on-site monitoring and temperature setting, the pressure gauge should be set in front of the valve, and the thermometer will be set at the insertion part of the temperature package
