Description

Technical Field

[0001] The utility model relates to the technical field of valves, and more specifically, to an intelligent heating temperature control valve. Background Art

[0002] Temperature control valve, also known as temperature control valve for short, is a typical application of flow control valve in the field of temperature control. Its basic principle is to control the outlet temperature of the equipment by controlling the inlet flow of heat exchangers, air conditioning units or other heating and cooling equipment and primary hot (cold) media. When the load changes, the flow is adjusted by changing the valve opening to eliminate the impact of load fluctuations and restore the temperature to the set value.

[0003] Patent authorization number CN219493128U discloses a temperature control valve, which intuitively displays the fluid temperature in the flow chamber and the hot flow channel through the temperature control component, so that the swirl component, temperature control component and valve core component cooperate with each other to adjust the hot and cold water to an appropriate temperature.

[0004] However, in the patent authorization number CN219493128U, the water inlets at both ends of the three passages are respectively connected to the cold and hot water pipes, and then flow into the mixing water pipe after passing through the mixing device. Since this solution cannot control the water inlet speed of the cold and hot water pipes separately, when the outlet water temperature needs to be adjusted, the flow rate of the hot water or cold water needs to be adjusted, and this solution cannot adjust the flow rate of the cold water pipe and the hot water pipe separately. Therefore, we propose an intelligent heating temperature control valve to solve the above-mentioned problems. Utility Model Content

[0005] In response to the problems existing in the prior art, the purpose of the utility model is to provide an intelligent heating temperature control valve, which can open the flow rate control mechanism, use the flow rate control mechanism to control the flow rate of hot water and cold water at the two water inlets respectively, adjust the flow ratio of cold and hot water, adjust the temperature of the output water, and thus adjust the temperature of the output water.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A smart heating temperature control valve comprises a valve body, two water inlets and a water outlet arranged on the valve body, and a flow rate control mechanism is installed at the water inlet end of the valve body;

[0008] The flow rate control mechanism includes a valve plate installed on the inner side of the water inlet, a sealing rubber ring embedded in the side wall of the valve plate and abutting against the inner wall of the valve body, a valve seat integrally formed on the outer side of the valve body and corresponding to the valve plate, a valve stem rotatably connected to the valve seat and transmission-connected to the valve plate, a mounting frame fixedly connected to the edge of the valve seat surface, and a stepping motor installed on the mounting frame and with a power output end transmission-connected to the valve stem;

[0009] A heating mechanism is installed at the water outlet;

[0010] The heating mechanism comprises a heater conductively connected to the water outlet;

[0011] A mixing assembly is installed inside the water outlet;

[0012] The mixing assembly includes a retaining frame fixedly connected to the inner side of the water outlet, and a blade rotatably connected to the lower side of the retaining frame;

[0013] A temperature sensor is installed above the mixing assembly.

[0014] Furthermore, a rotating seal is installed at the portion where the valve seat and the valve stem are combined.

[0015] Furthermore, a coupling is installed between the power output end of the stepper motor and the valve stem;

[0016] A bearing is installed at the position where the output shaft of the stepper motor is combined with the mounting frame.

[0017] Furthermore, a heating tube is installed inside the heater, and the heating tube is arranged in a spiral structure.

[0018] Furthermore, a plurality of blades are arranged at radial positions of the retaining frame, and a rotating shaft is connected to the middle portions of the plurality of blades.

[0019] Furthermore, a bearing is installed in the middle of the retaining frame, and the bearing is interference connected with the rotating shaft.

[0020] Furthermore, a pressure relief valve is installed at the bottom of the valve body.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] (1) In this scheme, the flushing blades are rotated in conjunction with the retaining frame to quickly mix the cold water and the hot water. The temperature of the water is detected by the temperature sensor. When the measured temperature is low, the heater is turned on to heat the outflowing water, and then the temperature is measured again by the temperature sensor.

[0023] When the temperature differs greatly from the actual required temperature, the flow rate control mechanism is turned on to control the flow rates of hot water and cold water at the two water inlets respectively, thereby adjusting the flow ratio of cold and hot water, adjusting the temperature of the output water, and further adjusting the temperature of the output water.

[0024] (2) In this solution, the heating tube is arranged in a spiral structure, which increases the area for heating water, and can quickly heat up the water passing through the heater, thereby improving the heating effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model. Example

[0032] See also Figure 1-4 , a smart heating temperature control valve, comprising a valve body 1 and two water inlets 2 and a water outlet 3 arranged at the valve body 1, and a flow rate control mechanism is installed at the water inlet end of the valve body 1;

[0033] The flow rate control mechanism includes a valve plate 4 installed on the inner side of the water inlet 2, a sealing rubber ring 5 embedded in the side wall of the valve plate 4 and abutting against the inner wall of the valve body 1, a valve seat 6 integrally formed on the outer side of the valve body 1 and corresponding to the valve plate 4, a valve stem 7 rotatably connected to the valve seat 6 and transmission connected to the valve plate 4, a mounting frame 8 fixedly connected to the edge of the surface of the valve seat 6, and a stepping motor 9 installed on the mounting frame 8 and with the power output end transmission connected to the valve stem 7;

[0034] A heating mechanism is installed at the water outlet 3;

[0035] The heating mechanism includes a heater 10 conductively connected to the water outlet 3;

[0036] A mixing assembly is installed inside the water outlet 3;

[0037] The mixing assembly includes a retaining frame 12 fixedly connected to the inner side of the water outlet 3, and a blade 13 rotatably connected to the lower side of the retaining frame 12;

[0038] A temperature sensor 15 is installed above the mixing assembly;

[0039] It should be noted that when the smart heating temperature control valve is in use, the two water inlets 2 provided at the valve body 1 are used to connect the cold water pipe and the hot water pipe respectively. After the hot water and the cold water enter the inner side of the valve body 1, the flushing blades 13 are used to cooperate with the retaining frame 12 to rotate, so that the cold water and the hot water are quickly mixed. The temperature of the water is detected by the temperature sensor 15. When the measured temperature is low, the heater 10 is turned on to heat the outflowing water, and then the temperature is measured again by the temperature sensor 15.

[0040] When the temperature is greatly different from the actual required temperature, the flow rate control mechanism is turned on to control the flow rates of hot water and cold water at the two water inlets 2 respectively, thereby adjusting the flow ratio of hot and cold water, adjusting the temperature of the output water, and thus adjusting the temperature of the output water;

[0041] Through the stepper motor 9 connected to an external control device, the power output end of the stepper motor 9 drives the valve stem 7 to rotate in coordination with the valve seat 6, thereby driving the valve plate 4 to rotate synchronously, thereby controlling the flow rate of hot water and cold water at the water inlet 2.

[0042] like Figure 1 , Figure 3 As shown, a rotary seal is installed at the joint of the valve seat 6 and the valve stem 7, and a coupling is installed between the power output end of the stepper motor 9 and the valve stem 7;

[0043] A bearing is installed at the position where the output shaft of the stepper motor 9 is combined with the mounting frame 8;

[0044] It should be noted that by setting a rotating seal, the sealing effect of the joint between the valve seat 6 and the valve stem 7 can be ensured to prevent leakage. At the same time, the bearing is used to reduce the friction between the output shaft of the stepper motor 9 and the mounting frame 8, and the rotation accuracy of the output shaft of the stepper motor 9 is ensured. By setting a coupling, the power output by the stepper motor 9 can be normally transmitted to the valve stem 7.

[0045] like Figure 3 As shown, a heating tube 11 is installed inside the heater 10, and the heating tube 11 is arranged in a spiral structure;

[0046] It should be noted that, by arranging the heating tube 11 in a spiral structure, the area for heating water is increased, and the water passing through the heater 10 can be quickly heated up, thereby improving the heating effect.

[0047] like Figure 4 As shown, a plurality of blades 13 are arranged at radial positions of the retainer 12, and a rotating shaft 14 is connected to the middle of the plurality of blades 13, a bearing is installed in the middle of the retainer 12, and the bearing is interference connected with the rotating shaft 14;

[0048] It should be noted that the friction between the rotating shaft 14 and the retaining frame 12 is reduced, thereby facilitating the rotation of the blade 13 .

[0049] like Figure 3 As shown, a pressure relief valve 16 is installed at the bottom of the valve body 1;

[0050] It should be noted that a pressure relief hole is provided on the valve body 1, and a pressure relief valve 16 is installed in the pressure relief hole. A sealing ring is installed at the junction of the pressure relief hole and the pressure relief valve 16. The setting of the pressure relief valve 16 can prevent the pressure in the valve body 1 from being too high. When the pressure in the valve body 1 reaches a certain threshold, the pressure prompts the pressure relief valve 16 to open to achieve the pressure relief effect.

[0051] When in use: the two water inlets 2 provided at the valve body 1 are used to connect the cold water pipe and the hot water pipe respectively. After the hot water and the cold water enter the inner side of the valve body 1, the flushing blade 13 is used to cooperate with the retaining frame 12 to rotate, so that the cold water and the hot water are quickly mixed. The temperature of the water is detected by the temperature sensor 15. When the measured temperature is low, the heater 10 is turned on to heat the outflowing water, and then the temperature is measured again by the temperature sensor 15.

[0052] At the same time, when the temperature is greatly different from the actual required temperature, the flow rate control mechanism is turned on to control the flow rates of hot water and cold water at the two water inlets 2 respectively, so as to adjust the flow ratio of hot and cold water, adjust the temperature of the output water, and then adjust the temperature of the output water;

[0053] Through the stepper motor 9 connected to an external control device, the power output end of the stepper motor 9 drives the valve stem 7 to rotate in coordination with the valve seat 6, thereby driving the valve plate 4 to rotate synchronously, thereby controlling the flow rate of hot water and cold water at the water inlet 2.

[0054] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
