Description

Technical Field

[0001] The utility model belongs to the technical field of valves and relates to a temperature control valve, in particular to an integrated radiator temperature control valve. Background Art

[0002] Thermostatic valves are used at the end of heating and air conditioning systems. They can automatically maintain the indoor temperature of the installation area according to the setting of the thermostatic controller, and play the role of switching flow. The application of thermostatic valves in radiators is as follows: after being heated by the water heater, the warm water with higher temperature flows into the radiator pipe from the hot water pipe in the thermostatic valve, and gradually cools down after the heat is dissipated through the pipe, forming cold water with lower temperature and flowing back to the cold water pipe in the thermostatic valve before being discharged.

[0003] Patent number CN201920070506.8 discloses an H-type valve for bottom-inlet and outlet radiators. According to the patent content and the attached drawings, the radiator temperature control valve under the prior art usually adopts an H-type valve composed of a warm water pipe and a cold water pipe, and the warm water pipe and the cold water pipe are independent of each other. The existing problems are: if the warm water heated by the water heater, the conventional radiator temperature control valve cannot directly compensate for the cooling, and an additional cold water compensation pipeline needs to be set up; and because the warm water pipe and the cold water pipe have similar structures, it is easy to connect the warm water inlet and the cold water inlet in reverse during installation. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated radiator temperature control valve in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an integrated radiator temperature control valve, including a valve body and a control structure;

[0006] The bottom of the valve body extends downward to form a warm water inlet and a cold water outlet, and the top is provided with a warm water outlet and a cold water inlet; a warm water passage is formed inside the valve body between the warm water inlet and the warm water outlet, and the warm water inlet, the warm water passage and the warm water outlet together constitute a warm water circulation pipeline of the temperature control valve. Similarly, a cold water passage is formed inside the valve body between the cold water inlet and the cold water outlet, and the three together constitute a cold water circulation pipeline of the temperature control valve;

[0007] A reflux passage is formed inside the valve body between the cold water outlet and the warm water inlet, and the reflux passage can connect the warm water circulation pipeline and the cold water circulation pipeline, so that the refluxed cold water flows into the reflux passage through the cold water reflux outlet; the valve body is integrally arranged;

[0008] Control structures are installed at the ports of the warm water passage, the cold water passage and the return passage. The control structure is mainly composed of a sealing mounting sleeve and a control valve stem. An inner sleeve thread is formed on the inner side wall of the sealing mounting sleeve. A valve stem thread that matches the inner sleeve thread is formed on the control valve stem, as well as a control valve core for opening and closing each passage.

[0009] In the above-mentioned integrated radiator temperature control valve, a mounting screw hole penetrating the top of the valve body is provided between the warm water outlet and the cold water inlet.

[0010] In the above-mentioned integrated radiator temperature control valve, the warm water passage, the cold water passage and the return passage are all provided with valve body internal threads on the inner side walls of the ports close to the end faces on both sides of the valve body, and the outer side wall of the sealing mounting sleeve is formed with sleeve external threads. The valve body internal threads cooperate with the sleeve external threads so that the control structure can be rotatably installed at the ports of each passage.

[0011] In the above-mentioned integrated radiator temperature control valve, O-rings are installed on the sealing mounting sleeve and the control valve core.

[0012] In the above-mentioned integrated radiator temperature control valve, an indicative mark is formed on the top of the valve body to help clarify the installation direction.

[0013] Compared with the prior art, the integrated radiator temperature control valve provided by the utility model has the following advantages: 1. By setting a reflux passage, the warm water circulation pipeline and the cold water circulation pipeline are not completely independent of each other. When the incoming warm water is overheated, cold water can be introduced through the reflux passage to mix with the warm water, directly performing temperature reduction compensation, improving the utilization rate of circulating water in the radiator, and being environmentally friendly and energy-saving;

[0014] Second, by adjusting the depth of the control structure in each channel, the size of the water flow in each channel and the mixing ratio of cold and warm water can be controlled, making the radiator temperature control more flexible and accurate, and more practical;

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figures 1 to 5 As shown, the integrated radiator temperature control valve includes a valve body 100 and a control structure 200. The valve body 100 is an integrated structure, and the interior mainly includes two pipeline paths, namely, a warm water circulation pipeline and a cold water circulation pipeline. The valve body 100 is provided with a through-mounting screw hole 101 at the top, and the top surface is provided with indicative markings of "LEFT" and "RIGHT" to facilitate the user to clearly identify the installation direction, thereby avoiding misconnecting the functional parts required to connect the warm water circulation pipeline and the cold water circulation pipeline.

[0025] like Figure 1 to Figure 2 As shown, the bottom of the valve body 100 extends downward to form a warm water inlet 111 and a cold water outlet 123, and the top is provided with a warm water outlet 113 and a cold water inlet 121, and a warm water passage 112 is formed inside the valve body 100 between the warm water inlet 111 and the warm water outlet 113. The warm water inlet 111 is connected to the water heater to input heated warm water into the temperature control valve, and the warm water flows through the warm water passage 112 and flows out from the warm water outlet 113, and the warm water outlet 113 is connected to the starting end of the pipe in the radiator, and the warm water inlet 111, the warm water passage 112 and the warm water outlet 113 together constitute the warm water circulation pipeline of the temperature control valve.

[0026] like Figure 3 to Figure 4As shown, a cold water passage 122 is formed inside the valve body 100 between the cold water inlet 121 and the cold water outlet 123. After the warm water has been radiated through the radiator pipe, it is cooled down to form cold water. The cold water inlet 121 is connected to the end of the pipe in the radiator and cold water is input therefrom. After the cold water flows through the cold water passage 122, it flows out from the cold water outlet 123 and returns to the hot water pump for heating. The cold water inlet 121, the cold water passage 122 and the cold water outlet 123 together constitute the cold water circulation pipeline of the temperature control valve.

[0027] A reflux passage 125 is formed inside the valve body 100 between the cold water outlet 123 and the warm water inlet 111 . The reflux passage 125 can connect the warm water circulation pipeline and the cold water circulation pipeline so that the refluxed cold water flows into the reflux passage 125 via the cold water reflux outlet 124 .

[0028] like Figure 2 and Figure 4 As shown, the warm water passage 112, the cold water passage 122 and the return passage 125 are all provided with valve body threads 102 on the inner side walls of the ports close to the end faces of both sides of the valve body 100, and the ports of the warm water passage 112, the cold water passage 122 and the return passage 125 are all equipped with control structures 200.

[0029] like Figure 5 As shown, the control structure 200 mainly includes a sealing installation sleeve 210 and a control valve stem 220. The side where the sealing installation sleeve 210 is located is defined as the front end. The control valve stem 220 is installed in the sealing installation sleeve 210 and extends backward to form a control valve core 222. The control valve core 222 is used to block the passage port. The outer wall of the sealing installation sleeve 210 is formed with a sleeve external thread 212. Through the matching of the valve body inner thread 102 and the sleeve external thread 212, the control structure 200 can be rotatably installed at the port of each passage. The inner wall of the sealing installation sleeve 210 is formed with a sleeve internal thread 211. The control valve stem 220 is formed with a valve stem thread 221 at the front end of the control valve core 222. The sleeve internal thread 211 is connected with the valve stem thread 221 to combine the sealing installation sleeve 210 with the control valve stem 220.

[0030] To further explain, an O-ring 230 is circumferentially arranged on the sealing mounting sleeve 210 at the front end of the sleeve external thread 212, and an O-ring 230 is also sleeved and installed on the control valve core 222 of the control valve stem 220. The O-ring 230 fits tightly against the inner wall of each passage to prevent the water flow in the passage from overflowing and affecting the normal use of the temperature control valve and the entire radiator system.

[0031] In conventional radiator temperature control valves, the warm water circulation pipeline and the cold water circulation pipeline are usually independent of each other, and the warm water and the cold water do not affect each other. Therefore, when the temperature of the warm water heated by the front water heater is too high, the radiator temperature control valve cannot directly adjust it, and an additional cold water compensation pipeline needs to be added for temperature reduction compensation. However, the utility model sets a return passage 125 inside the valve body 100, so that the warm water circulation pipeline and the cold water circulation pipeline are not completely independent of each other. When the incoming warm water is overheated, the return cold water can be introduced through the return passage 125 to mix with the warm water, and directly perform temperature reduction compensation, thereby improving the utilization rate of circulating water in the radiator and being more environmentally friendly and energy-saving.

[0032] Since the control structure 200 is rotatably connected to each passage port through a threaded connection, the switch of each passage and the size of the cold and warm water flow in the passage can be controlled by adjusting the depth of the control structure 200 screwed into each passage, thereby adjusting the mixing ratio of cold and warm water, making the radiator temperature control more flexible and accurate, and having higher practicality.

[0033] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0034] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
