Description

Technical Field

[0001] This utility model relates to the technical field of dynamic balancing valve actuators, and more specifically, to a spring-loaded touch dynamic balancing valve actuator. Background Technology

[0002] Currently, dynamic balancing valves are typically equipped with a dynamic balancing valve actuator during use. This actuator is used to adjust the valve's opening. The actuator has mechanical buttons that, when activated, display information about the valve's operation and any malfunctions on a screen.

[0003] However, mechanical buttons require holes to be made on the surface of the housing of the dynamic balancing valve actuator. The buttons protrude from the holes in the housing. Since the buttons need to be pressed up and down and the holes are usually fitted with clearance, the housing of the dynamic balancing valve actuator is easily exposed to moisture and short-circuited, which affects its normal operation.

[0004] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a spring-loaded touch dynamic balance valve actuator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spring-loaded touch-sensitive dynamic balancing valve actuator includes a housing, a panel mounted on the top of the housing, a controller corresponding to the panel mounted inside the housing, a touch spring and a display screen mounted on the side of the controller facing the panel, and the touch spring and display screen are electrically connected to the controller. The end of the touch spring abuts against the inner wall of the panel, and the position of the panel corresponding to the display screen is transparent.

[0008] Furthermore, the controller is equipped with an infrared receiver and an infrared transmitter, which are electrically connected to the controller. The panel corresponding to the positions of the infrared receiver and the infrared transmitter is transparent.

[0009] Furthermore, a faceplate is adhered to the upper surface of the panel, and the faceplate has through holes for data display and data transmission. The faceplate has touch marks corresponding to the touch spring positions.

[0010] Furthermore, the controller is electrically connected to a separate temperature sensor.

[0011] The beneficial effects of this utility model are:

[0012] 1. In this utility model, a touch spring is installed on the controller. The touch spring is located on the inner side of the panel and abuts against the inner wall of the panel. The panel is used to touch the touch spring, thereby triggering the controller to switch the content displayed on the display screen. At the same time, since the panel and the shell are sealed together, they are isolated from the outside and waterproof.

[0013] 2. In this utility model, by setting up an infrared receiver and an infrared transmitter, local data control is achieved by using infrared transmission.

[0014] 3. In this utility model, by setting a split-type temperature sensor, on the one hand, it is convenient to monitor the temperature of the medium flowing through the dynamic balance valve; on the other hand, it is convenient to replace the temperature sensor, and when replacing it, there is no need to drain the medium in the system.

[0021] 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.

[0022] Example: A spring-loaded touch-sensitive dynamic balancing valve actuator, such as... Figures 1-5As shown, the device includes a housing 1, a panel 2 is mounted on the top of the housing 1, a controller 3 corresponding to the panel 2 is mounted inside the housing 1, the controller 3 is located below the panel 2, a touch spring 4 and a display screen 5 are mounted on the side of the controller 3 facing the panel 2, and the touch spring 4 and the display screen 5 are electrically connected to the controller 3, and the end of the touch spring 4 abuts against the inner wall of the panel 2.

[0023] Panel 2 is made of PC material and is relatively thin (e.g., 0.8~1.6mm). Touch spring 4 is electrically connected to controller 3, serving as a capacitive sensing electrode, forming a distributed capacitance with the pads on controller 3. When a finger approaches touch spring 4, the previously stable electric field is disturbed, increasing the equivalent capacitance. The touch chip (e.g., TTP223) on controller 3 detects the capacitance change through an RC charging and discharging circuit. When the change exceeds a threshold, a trigger signal is output. The touch chip converts the capacitance change into a digital signal (e.g., high / low level) and transmits it to the main control MCU on controller 3. The main control MCU controls the switching of the display content on display screen 5 according to preset logic (e.g., single / long press).

[0024] Preferably, panel 2 can be fixedly installed on the top of housing 1 by adhesive (such as sealant), and the adhesive can form a sealing layer to seal between panel 2 and housing 1, thereby achieving waterproof isolation from the outside world; or, panel 2 can be installed on the top of housing 1 by snap-fit, and a sealing ring can be installed at the connection between panel 2 and housing 1 to seal between panel 2 and housing 1, thereby achieving waterproof isolation from the outside world.

[0025] Preferably, the area of ​​panel 2 corresponding to display screen 5 is transparent to facilitate viewing the content displayed on display screen 5. Of course, panel 2 can also be entirely transparent.

[0026] As a preferred option, such as Figure 3 and Figure 4 As shown, multiple mounting posts 101 are installed inside the housing 1. The controller 3 is fixedly installed inside the housing 1 by bolts 10 passing through the controller 3 and threaded onto the mounting posts 101.

[0027] Furthermore, such as Figure 2 and Figure 5 As shown, an infrared receiver 6 and an infrared transmitter 7 are installed on the controller 3. The infrared receiver 6 and the infrared transmitter 7 are electrically connected to the controller 3. The panel 2 corresponding to the positions of the infrared receiver 6 and the infrared transmitter 7 is transparent. By setting the infrared receiver 6 and the infrared transmitter 7, the infrared transmitter 7 is used to encode the control signals of the controller 3 into infrared light pulses, and the infrared receiver 6 is used to restore the received infrared light signals into digital signals and transmit them to the controller 3. The controller 3 is used to decode the received signals and generate transmission commands. By setting the infrared receiver 6 and the infrared transmitter 7, local data control is achieved using infrared transmission.

[0028] Furthermore, such as Figure 1 As shown, a faceplate 8 is adhered to the upper surface of the panel 2. The faceplate 8 has through holes 801 for data display and data transmission. In this embodiment, there are three through holes 801, namely the through hole 801 corresponding to the display screen 5, the through hole 801 corresponding to the infrared receiver 6, and the through hole 801 corresponding to the infrared transmitter 7.

[0029] The faceplate 8 is made of PC material and is relatively thin. The thickness of the faceplate 8 can be controlled to avoid affecting the use of the touch spring 4 due to excessive thickness. The faceplate 8 has a touch mark 802 corresponding to the position of the touch spring 4. By setting the touch mark 802, the position of the touch spring 4 can be easily identified, thereby facilitating the touch of the touch spring 4.

[0030] By setting the faceplate 8, it serves several purposes: first, it can be used as decoration to enhance the aesthetics of the dynamic balance valve actuator; second, it can be used as a protective film to provide some protection for the panel 2; and third, when the user's finger touches the faceplate 8, the uniform dielectric properties of the faceplate 8 contribute to a stable electric field distribution, ensuring the sensitivity of the touch spring 4.

[0031] Furthermore, such as Figure 1 As shown, the controller 3 is electrically connected to a split-type temperature sensor 9, such as a PT1000. The temperature sensor facilitates monitoring of the temperature of the medium flowing through the dynamic balancing valve; its split design allows for easy replacement without needing to drain the system's medium during replacement. Preferably, a sealing ring is installed at the connection point between the housing 1 and the cable of the split-type temperature sensor 9 to provide waterproofing.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
