Description

Technical Field

[0001] This utility model relates to the field of temperature control valve technology, and more specifically, to a temperature control valve with dual-channel temperature control adjustment. Background Technology

[0002] A thermostatic valve is an automated valve device that controls the output temperature by regulating the flow rate of fluids (such as hot water, steam, and cooling water). Its core principle is to use a temperature sensor to monitor the target temperature and then automatically adjust the valve opening via an actuator (such as an electric, pneumatic, or self-operated device), thereby achieving closed-loop control of the system temperature. Simply put, it acts like a "smart temperature regulator" and is widely used in scenarios requiring stable temperature control, such as HVAC systems, industrial equipment, and energy systems.

[0003] Currently, traditional single-channel thermostatic valves can only regulate the flow of one heat medium (such as hot water or steam), and cannot automatically deliver it to different channels according to the temperature requirements during medium transportation. Manual control is required, which is cumbersome. Therefore, a dual-channel thermostatic valve is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a temperature control valve with dual-channel temperature control, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a temperature control valve with dual-channel temperature control adjustment, including a base, on which a flow guiding component is provided;

[0006] The flow guiding assembly includes a flow guiding shroud disposed on the top of the base, a first inner liner frame disposed between the flow guiding shroud and the base, a temperature bulb disposed at the bottom of the first inner liner frame, and the temperature bulb is filled with a heat-absorbing deformation mixture, and a top rod is slidably connected to the middle of the temperature bulb.

[0007] The outer side of the temperature pack is provided with an inner liner, the outer side of the inner liner is provided with a central sleeve, the top end of the top rod is provided with a second inner liner frame, the outer side of the second inner liner frame extends to the top of the inner cavity of the central sleeve, and the central sleeve is fixedly connected to the second inner liner frame.

[0008] Optionally, in a possible implementation, a flow divider is provided in the middle of the flow guide, the bottom of the flow divider extends to the outside of the central sleeve, a first flow guide channel is provided between the top of the flow divider and the flow guide, a second flow guide channel is provided between the bottom of the flow divider and the flow guide, the first flow guide channel extends to the top of the flow guide, the second flow guide channel extends to the side of the flow guide, a second sealing ring is provided on the bottom outside of the central sleeve, a first sealing ring is provided on the outside of the central sleeve, and the first sealing ring abuts against the flow divider.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] By sensing the temperature change of the medium through the temperature bulb, the push rod and the central sleeve are driven to lift and lower in linkage, automatically switching the opening and closing states of the first and second guide channels, so that the high temperature medium can be diverted to different outlets as needed without manual intervention;

[0011] The flow divider, combined with the dual-channel structure, can precisely control the flow of the medium according to temperature changes. When the temperature is low, the medium is preferentially transported through the second channel. When the temperature exceeds the threshold, the temperature bulb pushes the top rod to move the center sleeve upward, sealing the second channel and opening the first channel, thus achieving precise flow division in different temperature ranges and meeting the temperature control needs of multiple scenarios.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figures 1-4 The temperature control valve shown in the dual-channel temperature control adjustment, through the flow guide component set on the base 1, senses the change in medium temperature through the temperature bulb 4, drives the top rod 5 and the center sleeve 7 to lift and lower in linkage, automatically switching the opening and closing state of the first flow guide channel 10 and the second flow guide channel 11, realizing the diversion of high temperature medium to different outlets as needed, without manual intervention, and the specific structural settings of the component are as follows;

[0020] The flow guiding assembly includes a flow guiding shroud 2 disposed on the top of the base 1, a first inner liner frame 3 disposed between the flow guiding shroud 2 and the base 1, a heat-generating bulb 4 disposed at the bottom of the first inner liner frame 3, and the heat-generating bulb 4 is filled with a heat-absorbing deformation mixture, and a top rod 5 is slidably connected to the middle of the heat-generating bulb 4.

[0021] The outer side of the heating element 4 is provided with an inner liner 6, the outer side of the inner liner 6 is provided with a central sleeve 7, the top of the top rod 5 is provided with a second inner liner frame 8, the outer side of the second inner liner frame 8 extends to the top of the inner cavity of the central sleeve 7, and the central sleeve 7 is fixedly connected to the second inner liner frame 8.

[0022] Specifically, as shown in the attached document Figure 1 , 2 As shown in Figures 3 and 4, the high-temperature medium is transported from the bottom of the base 1 into the base 1. After being gathered by the central sleeve 7, the medium is transported through the second inner liner frame 8 into the second guide channel 11. The high-temperature medium comes into contact with the heat-absorbing and deforming mixture inside the heat-absorbing bulb 4, such as wax. It deforms under heat and causes the push rod 5 to move upward. When the push rod 5 moves upward, it drives the second inner liner frame 8 and the central sleeve 7 to move, thereby causing the second sealing ring 13 to detach from the first inner liner frame 3. The high-temperature medium is then discharged from the top of the guide shroud 2 through the first guide channel 10, so that both the second guide channel 11 and the first guide channel 10 can form guide channels.

[0023] A flow divider 9 is provided in the middle of the flow guide shroud 2. The bottom of the flow divider 9 extends to the outside of the central sleeve 7. A first flow guide channel 10 is provided between the top of the flow divider 9 and the flow guide shroud 2. A second flow guide channel 11 is provided between the bottom of the flow divider 9 and the flow guide shroud 2. The first flow guide channel 10 extends to the top of the flow guide shroud 2. The second flow guide channel 11 extends to the side of the flow guide shroud 2. A second sealing ring 13 is provided on the bottom outside of the central sleeve 7. A first sealing ring 12 is provided on the outside of the central sleeve 7. The first sealing ring 12 abuts against the flow divider 9.

[0024] Specifically, as shown in the attached document Figure 2 , 3 As shown in Figure 4, the high-temperature medium continues to contact the temperature bulb 4, the push rod 5 continues to move upward and allows the central sleeve 7 to abut against the bottom of the diverter plate 9, thereby sealing the second guide channel 11, and thus allowing the medium to be discharged only through the first guide channel 10.

[0025] The specific working principle is as follows: the medium enters from the bottom of the base 1, is gathered by the central sleeve 7 and flows into the second guide channel 11, and is discharged from the side outlet of the guide hood 2. At this time, the temperature bulb 4 is not heated, the top rod 5 is in a low position, the second sealing ring 13 presses the first inner liner frame 3, and closes the first guide channel 10.

[0026] When the high-temperature medium comes into contact with the temperature bulb 4, the mixture inside it expands due to heat, pushing the push rod 5 upward. The push rod 5 drives the second inner liner frame 8 and the fixedly connected center sleeve 7 to rise synchronously, so that the second sealing ring 13 is separated from the first inner liner frame 3. One path is discharged from the side outlet through the second guide channel 11, and the other path is discharged from the top outlet through the gap between the first inner liner frame 3 and the center sleeve 7.

[0027] The push rod 5 continues to move upward until the top of the center sleeve 7 presses against the bottom of the diverter plate 9. The first sealing ring 12 presses against the diverter plate 9, completely sealing the second guide channel 11. The medium is switched to the first guide channel 10 and discharged from the top outlet. The medium temperature decreases, the mixture in the temperature bulb 4 contracts, and the push rod 5 moves downward under the action of gravity or the reset mechanism. The center sleeve 7 descends synchronously, resealing the second guide channel 11 and restoring the initial state.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
