The temperature measuring modes of the existing intelligent temperature control valve include the following three types: 1. external wiring temperature measurement, 2 valve body temperature measurement, and 3 temperature measurement probes penetrate through the valve rod for temperature measurement. External wiring temperature measurement is arranged in the fluid through the valve with the temperature probe, the medicament that adds in the heating flowing water can make the incrustation scale crystallization produce on the probe, direct influence is to the measurement of actual fluid temperature, thereby influence heating power company and produce the deviation to the control of heating temperature, finally influence user's heating effect, this kind of temperature measurement mode is generally drawn forth the wiring alone from the controller outside the valve, the temperature measurement point is that the trompil is placed temperature probe in the valve body in the valve below and is carried out the temperature measurement, external lead wire is considered very easily to destroy, temperature control and data acquisition to the heating company cause very big puzzlement, still can cause unnecessary cost of maintenance.
The temperature measurement of the valve body is to place a temperature measurement probe in the valve body, and the temperature measurement probe is pressed on the valve body to measure the temperature of the valve body for temperature acquisition, so that the temperature measurement mode cannot place the temperature measurement probe at the flowing position of fluid, can only measure the temperature on the valve body in a heat conduction mode to further estimate the temperature of the fluid, cannot reflect the real temperature of the fluid, and can be greatly influenced by the external temperature. The temperature measuring probe penetrates through the valve rod for measuring temperature, namely a through hole is processed in the middle of the valve rod, the temperature measuring probe penetrates through the valve rod, but in the mode, sealing needs to be arranged between the temperature measuring probe and the valve rod and between the valve rod and the valve body, the sealing performance of the valve is affected, and the risk of leakage is caused subsequently.
