Background
The water floor heating is a heating mode which takes hot water as a medium, circulates in a heating pipeline buried below the ground, heats the whole floor, and then supplies heat to the indoor through the ground in a radiation and convection heat transfer mode.
In the actual installation process of the floor heating, due to the installation operation of installation personnel and uneven bottom surface, all floor heating pipes cannot be guaranteed to be on the same horizontal plane, water distribution and collection devices and main water supply and return pipes arranged on the floor heating pipes are generally higher than the floor heating pipes, and the nodes are easy to generate a gas collection phenomenon. Once air enters the floor heating pipeline, a blocking phenomenon is generated, so that the pipeline is not circulated, and normal heating is affected, which is a common reason for the fact that the floor heating is unheated; on the other hand, most of the current electronic temperature controllers are also called electric heating actuators, and the electric heating actuators have the advantages of complex structure, small thrust, high average failure and high technical requirements on field maintenance personnel.
Currently, there is a non-electric control temperature control head, which is used for controlling the opening degree of a valve rod through sensing the ambient temperature and then feeding back, for example, a temperature control head disclosed in application number CN104514913B, and the current prior art represented by the temperature control head can refer to the description of the background part of the specification, wherein the temperature control head comprises a temperature sensor, which is usually a liquid sensor; a temperature change of the environment causes a subsequent volume change of the liquid contained in the sensor, which in turn causes a displacement of the internal mechanism, wherein a subsequent closure of the valve or orifice is coupled to the device; this ultimately generates a modulation of the flow of heat transfer fluid into the heating body, and then a modulation of the variation of the heat delivered by the latter.
The temperature control head can generate displacement output through sensing the room temperature by the temperature sensitive medium to realize the control of the opening of the valve body, and the temperature control head has the function of controlling the opening of the valve body, but on one hand, the temperature control head has more parts, complex structure and poor installation and adjustment convenience; on the other hand, the temperature control head only has the function of controlling the opening of the valve body through sensing the ambient temperature feedback, is directly arranged on a single control valve body, works independently with an exhaust mechanism and a throttle valve of a heating and ventilation system, and has low system integration level; in yet another aspect, the temperature control head senses only room temperature and does not sense the temperature of the heating and ventilation medium fluid, which is also an important factor affecting the heat energy released by heating and ventilation.

Referring to fig. 6-10, the pilot-operated temperature control head 4 includes a housing 13 connected to a valve body in any manner, and this embodiment is not limited thereto. The top of the valve body of the regulating valve 1 is a threaded connection end, the shell 13 is connected to the valve body through the connecting cap 14 in a threaded manner, the top of the connecting cap 14 is higher than the valve body after installation, a radial inward flange part 141 is arranged on the connecting cap 14, the shell 13 is integrally provided with a protruding outer connecting tube 131, the end part of the outer connecting tube 131 is provided with a radial outward clamping hook part 132, the flange part 141 is in contact fit with the clamping hook part 132 up and down, and the purpose is that the connecting cap 14 has a vertical limiting function on the shell 13.
