Description

Technical Field

[0001] This utility model relates to the field of thermostatic control valves for underfloor heating, specifically a thermostatic control valve for underfloor heating. Background Technology

[0002] A thermostatic control valve is a type of valve used to achieve the above-mentioned purpose. Typically, each user in the system has an indoor temperature controller and a thermostatic control valve. When the indoor temperature does not exceed the temperature set by the controller, the thermostatic control valve remains open, allowing the fluid medium carrying heat to flow smoothly through the user's piping system. Once the indoor temperature exceeds the controller's set temperature, the thermal expansion device in the thermostatic control valve actuates the valve core, closing the valve and preventing the indoor temperature from rising further. Similarly, when the indoor temperature is lower than the controller's set temperature, the thermostatic control valve opens, allowing the fluid medium carrying heat to continue flowing through the user's piping system.

[0003] Current thermostatic control valves can only monitor the temperature of the fluid medium inside the valve tube and cannot detect the indoor temperature. When the indoor temperature reaches the preset value, the valve tube can be temporarily closed to achieve the purpose of intelligent energy saving. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a floor heating thermostatic control valve to solve the problems mentioned in the background art. It has the advantage of temporarily closing the valve pipe when the indoor temperature reaches a predetermined value, thereby achieving intelligent energy saving.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a floor heating thermostatic control valve, comprising a valve body, the valve body including an inlet pipe and an outlet pipe, a flow pipe provided between the inlet pipe and the outlet pipe, a thermostatic controller provided on one side of both the outlet pipe and the flow pipe, the thermostatic controller including a rotating cover, an annular plate fixedly connected to the rotating cover, a first screw plate snapped onto the annular plate, a second screw plate threadedly connected to the first screw plate, a connecting plate fixedly connected to the second screw plate, a limiting rod integrally connected to the rotating cover to restrict the rotation of the second screw plate, a paraffin heating element provided below the connecting plate, a valve stem connected to the paraffin heating element, and a sealing disc sleeved on one end of the valve stem.

[0006] By adopting the above technical solution, this solution adds two thermostats: one for monitoring the temperature of the fluid medium inside the valve body, and the other for detecting the indoor temperature. When the indoor temperature reaches a predetermined value, the fluid medium inside the valve body will be cut off to prevent the temperature from getting too high, thus saving energy. The other thermostat will also cut off the fluid medium when its temperature is too high. The adjustment process of the thermostat is as follows: rotating the rotating cover drives the annular plate to rotate, which in turn drives the first screw plate to rotate. The second screw plate is restricted by the limit rod and cannot rotate. Therefore, the second screw plate moves up and down, which drives the paraffin heating bulb to move, which in turn drives the valve stem to move. The movement of the valve stem drives the closing disc to move. After the closing disc is in a suitable position, the paraffin heating bulb will cut off the fluid medium when the temperature changes due to the temperature.

[0007] As a further embodiment of this utility model: a return plate is provided inside the constant temperature controller, a return spring is provided inside the return plate, and a return disc located at one end of the return spring is fixedly connected to the part of the valve stem inside the return plate.

[0008] By adopting the above technical solution, the valve stem moves and drives the reset plate to move. After the reset plate moves downward, it will compress the reset spring, and the reset spring will exert a force on the valve stem to return it to its original position.

[0009] As a further improvement of this utility model: the first screw plate is integrally connected to an extension plate in the circumferential direction, and a stabilizing spring is provided between the extension plate and the annular plate.

[0010] By adopting the above technical solution, the setting of the stabilizing spring allows the extension plate and the annular plate to be in a relatively stable state.

[0011] As a further improvement of this utility model: the end face of the limiting rod is hexagonal, and the second screw plate is provided with a hexagonal groove that fits with the limiting rod.

[0012] By adopting the above technical solution, one end of the limiting rod is located in the hexagonal groove of the second screw plate, thus restricting the rotation of the second screw plate.

[0013] As a further embodiment of this utility model: the exhaust valve includes a connecting valve that is threadedly connected to the flow pipe, the middle of the connecting valve is provided with an annular groove, the connecting valve is snapped with a connecting body through the annular groove, the side of the connecting body is provided with an exhaust groove that communicates with the outside, and the connecting valve is threadedly connected with a sealing member that penetrates the connecting body.

[0014] By adopting the above technical solution, the connecting valve is engaged with the connecting body through an annular groove, and the rotating sealing part allows the exhaust groove to connect with the flow pipe, thereby playing the role of exhaust.

[0015] Preferably, the closure includes a closure rod that is threadedly connected to the connecting valve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This solution incorporates two thermostats: one monitors the temperature of the fluid medium within the valve body, and the other detects the indoor temperature. When the indoor temperature reaches a predetermined value, the fluid medium within the valve body will be shut off to prevent overheating and save energy. The other thermostat detects the fluid medium within the valve body and also shuts it off when the fluid medium temperature is too high. The thermostat adjustment process is as follows: rotating the rotating cover drives the annular plate to rotate, which in turn drives the first screw plate to rotate. The second screw plate is restricted by the limit rod and cannot rotate. Therefore, the second screw plate moves up and down, causing the paraffin heating bulb to move, which in turn drives the valve stem to move. The movement of the valve stem drives the closing disc to move. After the closing disc is in the appropriate position, the paraffin heating bulb will shut off when the temperature changes due to temperature influences. Attached Figure Description
