What Faults Often Occur When The Thermostatic Radiator Valve Is Used?

Thermostatic radiator valve is composed of PID temperature controller, control valve, electronic electric actuator, sensor and capillary, etc. According to the application, it is divided into heating type and cooling type. Heating type and cooling type only need to adjust the execution mode. The thermostatic radiator valve is suitable for the control of large diameter and heat transfer oil. The biggest feature of this valve is that it only has an ordinary 220V power supply, and adopts its own PID temperature control system to directly adjust the temperature of steam, hot water, and hot oil and automatically adjust and Control gas. It can also be used to prevent overheating or heat exchange. The thermostatic radiator valve has a simple structure and is easy to operate. It has a wide temperature range and fast response time. The sealing performance is reliable and can be freely adjusted during operation. Therefore, it is widely used for hot water supply in chemical, petroleum, food, textile, hotels and restaurants.

(1) The spool is not closed: The solution to closing the air valve is to increase the pressure of the air source or relax the preload of the spring (ie, reduce the starting pressure of the air chamber). The solution for the exhaust valve is to increase the spring preload and increase the initial pressure.

(2) The push rod moves slowly or does not move: Check the diaphragm, rolling diaphragm and gasket for air leakage due to aging or rupture.

(3) The return difference is large: whether the push rod is bent, whether the packing gland is pressed too tightly,
