Description

Technical Field

[0001] This utility model relates to the field of floor heating thermostatic control valves, specifically a floor heating thermostatic control valve with an electric heating actuator. 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 do not have actuators and require manual valve opening, which is inefficient and needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a floor heating thermostatic control valve with an electric heating actuator to solve the problems mentioned in the background art. It has the advantages of having an actuator, which makes it convenient to open and close the valve pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a floor heating thermostatic control valve with an electric heating actuator, 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, an actuator body provided in the inlet pipe, the actuator body including a housing, an electric heating valve core provided inside the housing, a concave plate connected to the top rod body of the electric heating valve core, a movable rod connected to one end of the concave plate, and a movable disc connected to one end of the movable rod.

[0006] By adopting the above technical solution, after the electric heating valve core is energized, it will drive the top rod body to move upward, which in turn drives the concave plate to move, which in turn drives the movable rod to move. The movement of the movable rod drives the movable disc to move to the appropriate position, thereby achieving the purpose of opening and closing.

[0007] As a further embodiment of this utility model: a return spring is sleeved on the concave plate, and the return spring is located between the top of the outer shell and the concave plate.

[0008] By adopting the above technical solution, when the electric heating valve core is not energized, the concave plate will move downward under the action of the return spring, thereby driving the movable rod to move. The movement of the movable rod will drive the movable disc to move until the movable disc closes the valve body.

[0009] As a further improvement of this utility model, a positioning spring is sleeved on the top rod body of the electric heating valve core.

[0010] By adopting the above technical solution, the positioning spring increases the stability of the push rod body during movement.

[0011] As a further embodiment of this utility model: a first return plate is provided inside the actuator body, a first return spring is provided inside the first return plate, and a first reset disc located at one end of the first return spring is fixedly connected to the portion of the movable rod inside the first return plate.

[0012] By adopting the above technical solution, the movement of the movable rod will drive the first reset plate to move, thereby compressing the first reset spring. The first reset spring allows the movable rod to return to its original position.

[0013] As a further embodiment of this utility model: the constant temperature controller includes 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.

[0014] 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.

[0015] As a further improvement of this utility model: the constant temperature controller is provided with a second return plate, the second return plate is provided with a second reset spring, and the part of the valve stem located inside the second return plate is fixedly connected to a second reset disc located at one end of the second reset spring.

[0016] By adopting the above technical solution, the valve stem moves and drives the second reset plate to move. After the second reset plate moves downward, it will compress the second reset spring. The second reset spring applies a force to the valve stem to return it to its original position.

[0017] As a further embodiment 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] When the electric heating valve core is energized, it will drive the top rod body to move upward, which in turn drives the concave plate to move, which in turn drives the movable rod to move. The movement of the movable rod drives the movable disc to the appropriate position, thus achieving the purpose of opening and closing. Attached Figure Description

A flow pipe 4 is provided between the inlet pipe 3 and the outlet pipe 2. A thermostat 5 is provided on one side of both the outlet pipe 2 and the flow pipe 4. An actuator body 6 is provided on the inlet pipe 3. The actuator body 6 includes a housing 7. An electric heating valve core 8 is provided inside the housing 7. The top rod body 32 of the electric heating valve core 8 is connected to a concave plate 9. One end of the concave plate 9 is connected to a movable rod 10. One end of the movable rod 10 is connected to a movable disc 11.

[0030] The concave plate 9 is fitted with a return spring 12, which is located between the top of the outer shell 7 and the concave plate 9.

[0031] The top rod body 32 of the electric heating valve core 8 is fitted with a positioning spring 13.

[0032] The actuator body 6 is provided with a first return plate 14, and a first return spring 15 is provided in the first return plate 14. The part of the movable rod 10 located in the first return plate 14 is fixedly connected to a first reset disk 16 located at one end of the first return spring 15.

[0033] The constant temperature controller 5 includes a rotating cover 17, an annular plate 18 fixedly connected to the rotating cover 17, a first screw plate 19 snapped onto the annular plate 18, a second screw plate 20 threadedly connected to the first screw plate 19, a connecting plate 21 fixedly connected to the second screw plate 20, a limiting rod 22 integrally connected to the rotating cover 17 to restrict the rotation of the second screw plate 20, a paraffin heat bulb 23 disposed below the connecting plate 21, a valve stem 24 connected to the paraffin heat bulb 23, and a sealing disc 25 sleeved on one end of the valve stem 24.

[0034] The thermostat 5 is provided with a second return plate 26, and a second return spring 27 is provided in the second return plate 26. The part of the valve stem 24 located in the second return plate 26 is fixedly connected to a second return disk 28 located at one end of the second return spring 27.

[0035] The first screw plate 19 is integrally connected to an extension plate 29 in the circumferential direction, and a stabilizing spring 30 is provided between the extension plate 29 and the annular plate 18.

[0036] The end face of the limiting rod 22 is hexagonal, and the second screw plate 20 is provided with a hexagonal groove 31 that fits with the limiting rod 22.

[0037] Working principle:

[0038] When the electric heating valve core 8 is energized, it will drive the top rod body 32 to move upward, which in turn drives the concave plate 9 to move, which in turn drives the movable rod 10 to move. The movement of the movable rod 10 drives the movable plate 11 to move to the appropriate position, thereby achieving the purpose of opening and closing.

[0039] This solution includes two thermostats 5. One monitors the temperature of the fluid medium inside the valve body 1, and the other detects the indoor temperature. When the indoor temperature reaches a predetermined value, the fluid medium inside the valve body 1 will be cut off to prevent overheating and save energy. The thermostat also detects the fluid medium inside the valve body 1 and cuts off the fluid medium when its temperature is too high. The adjustment process of the thermostat 5 is as follows: rotating the rotating cover 17 drives the annular plate 18 to rotate, which in turn drives the first screw plate 19 to rotate. The second screw plate 20 is restricted by the limit rod 22 and cannot rotate. Therefore, the second screw plate 20 moves up and down, which drives the paraffin heating bulb 23 to move, which in turn drives the valve stem 24 to move. The movement of the valve stem 24 drives the closing plate 25 to move. After the closing plate 25 is in a suitable position, the paraffin heating bulb 23 will cut off the fluid medium when the temperature changes due to the temperature.
