Description

Technical Field

[0001] This utility model relates to the field of thermostatic control valves, specifically a floor heating thermostatic control valve with a flow meter. 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 flow meters, so they cannot control the flow rate of the fluid medium. Reducing the flow rate of the fluid medium can reduce costs, so this needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a floor heating thermostatic control valve with a flow meter to solve the problems mentioned in the background art. It has the advantage of controlling the flow rate of fluid media, thereby reducing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a floor heating thermostatic control valve with a flow meter, 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 the inlet pipe, a flow meter body provided on one side of the outlet pipe, an air vent valve provided in the flow pipe, the flow meter body including a first threaded plate threadedly connected to the inlet pipe, a second threaded plate threadedly connected to the first threaded plate, a cavity provided at the lower end of the second threaded plate, a communicating groove provided on the side of the second threaded plate communicating with the cavity, and a flow groove penetrating the first threaded plate provided on the side of the first threaded plate.

[0006] By adopting the above technical solution, the flow meter body is used to control the flow rate of the fluid medium, thereby achieving the purpose of cost control. The process is as follows: rotating the second threaded plate causes the second threaded plate to move along its own axis. The movement of the second threaded plate causes the cavity to move up and down. When the cavity moves to the flow channel, the fluid medium will flow into the cavity along the flow channel and then into the outlet pipe. When the cavity is not in the flow channel, the fluid medium will be cut off and unable to flow.

[0007] As a further embodiment of this utility model: the second threaded plate is threadedly connected to a third threaded plate, and a piston rod is provided inside the third threaded plate, with a closed disc integrally connected to the lower end of the piston rod.

[0008] By adopting the above technical solution, rotating the third threaded plate drives the piston rod to move up and down, which in turn drives the closed disc to move. When the closed disc moves to the connecting groove, it will not play a blocking role. When the closed disc moves to the bottom of the connecting groove, it will play a blocking role.

[0009] As a further embodiment of this utility model: a fixed plate is fixedly connected to the upper end of the piston rod, and a spring is provided between the fixed plate and one end of the second threaded plate.

[0010] By adopting the above technical solution and incorporating the spring, the stability of the piston rod is increased.

[0011] As a further improvement of this utility model, a rotating sleeve is integrally connected to the outer side of the second threaded plate.

[0012] By adopting the above technical solution, the rotating sleeve facilitates the rotation of the second threaded 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] As a further embodiment of this utility model: the sealing member includes a sealing rod that is threadedly connected to the connecting valve, and a sealing plate is snapped onto the upper end of the sealing rod.

[0016] By adopting the above technical solution, the rotating sealing plate drives the sealing rod to rotate, thereby adjusting the position of the sealing rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The flow meter body is used to control the flow rate of the fluid medium, thereby controlling the cost. The process is as follows: the second threaded plate is rotated so that the second threaded plate moves along its own axis. The movement of the second threaded plate causes the cavity to move up and down. When the cavity moves to the flow channel, the fluid medium will flow into the cavity along the flow channel and then into the outlet pipe. When the cavity is not in the flow channel, the fluid medium will be cut off and cannot flow. Attached Figure Description
