Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Without loss of generality, the ball valve shown in the figure is taken as a description main body in the embodiment, and the temperature balance valve of the internet of things provided by the scheme is explained in detail. And after the assembly is finished, the inlet and the outlet of the valve are communicated and arranged in a user system pipeline. It should be understood that the valve opening size of the balance valve and the flow curve thereof, which are parameters related to the valve function, do not constitute a substantial limitation to the internet of things temperature balance valve claimed in the present application.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of an overall structure of the temperature balance valve of the internet of things according to the embodiment, and fig. 2 is a cross-sectional view of an internal structure of the temperature balance valve of the internet of things according to the embodiment.

The temperature balance valve of the Internet of things comprises an actuator 10, a valve 20 and a temperature sensor 30, wherein the actuator 10 is in signal interaction with a control system and provides driving power for adjusting the opening degree of the valve. Specifically, the power output end of the actuator 10 drives the valve core 22 to adjust the opening degree through the valve rod 21 of the valve 20. The temperature sensor 30 is used for collecting the temperature of the medium in the valve and feeding back the temperature to the actuator 10 in real time to serve as basic data for system control.

In the scheme, a temperature measuring rod 31 of a temperature sensor 30 is inserted into a valve rod 21 and a valve core 22, and a temperature measuring end 311 of the temperature sensor is arranged in an accommodating cavity 221 of the valve core 22 communicated with a medium flow channel and is contacted with water flow in a valve 20 to collect the temperature of the medium; the terminals 312 are disposed in the actuator 10 and are in signal connection with the circuit board 11 of the actuator 10 to realize connection with the communication circuit. With this arrangement, the temperature sensor 30 is completely disposed in the actuator 10 and the valve 20, and a signal line (not shown) is disposed inside the actuator, so as to avoid the aging damage and the like caused by exposure. Referring to fig. 3, fig. 3 is a schematic diagram of the valve core and valve seat in a fully open state, in which the internal elements of the actuator 10 are omitted to clearly show the built-in state of the temperature measuring rod 31.

Referring to fig. 2 and 3, the valve body 23 of the valve 20 is provided with a stem fitting hole 231, wherein the stem fitting hole 231 is located at the upper end of the valve body 23 based on the illustrated fitting relationship in which the actuator 10 is located above the valve 20. The valve rod 21 is inserted into the valve rod adapting hole 231, and a first sealing ring 24 is arranged between the valve rod adapting hole and the valve rod adapting hole; meanwhile, a second seal ring 25 is arranged between the first insertion hole 211 of the valve rod 21 and the temperature measuring rod 31. In this way, a reliable sealing of the respective assembly relationship in the state of use can be ensured. It should be noted that the above sealing relationship is not limited to the structure and arrangement shown in the drawings, and it is within the scope of the present application as long as a reliable seal between the adapter members is satisfied.

In order to effectively improve the operability of the temperature balance valve of the internet of things, an auxiliary circuit board 19 with an NFC (Near Field Communication) function may be disposed above the circuit board 11, and specifically, the auxiliary circuit board may be connected in a form of a pin, so that the assembly and maintenance are convenient and fast. During the use, the parameter of thing networking temperature balance valve is set up to the equipment that accessible cooperation has the NFC reading and writing. Correspondingly, the circuit board 11 may have at least one communication function of wireless communication such as NB (Narrow Band Internet of things)/Lora (Long Range Radio)/4G/5G, etc. or wired communication such as RS485/Mbus (remote meter reading system); the operating power supply provided to the circuit board 11 may be an external power supply or a built-in battery.

It is understood that the specific implementation of the above power supply method is not the core invention point of the present application, and therefore, the detailed description thereof is omitted.

In order to further optimize the structure and reduce the overall dimensions of the product, the valve body 23 of the valve 20 is preferably directly connected to the housing 12 of the actuator 10. As shown, the valve body 23 on the periphery of the valve rod 21 is provided with a first mounting surface 232, the shell 12 of the actuator 10 is provided with a second mounting surface 1211, and the valve 20 and the actuator 10 are detachably connected through the first mounting surface 232 and the second mounting surface 1211; the executor and the valve lug connection of this scheme adopt transition connection components such as exempting from support, connecting sleeve, greatly reduced product overall dimension. The occupied space is small. It should be understood that the "detachable connection" can be realized in different ways, as long as the assembly and maintenance convenience are facilitated; for example, but not limited to, the threaded fastener is used as shown in the figure, and as shown in fig. 3, the valve body 23 is provided with a threaded hole, the housing 12 (the lower housing 121) of the actuator 10 is provided with a countersunk bolt adapting hole, and the countersunk bolt is screwed in from the inner side of the housing 12 to realize the detachable connection.

For the ball valve core 22, the flow regulating structure adapted to the ball valve core is arranged on the valve seat 233 of the valve body 23, and as shown in fig. 2 and 3, the structure with the flow regulating function can be integrally formed with the ball valve seat 233, so that the ball valve core 22 has the characteristics of simple structure and good processing manufacturability. Please refer to fig. 4 for a schematic diagram of the flow channel hole areas with different opening degrees of the valve. The shaded area represents the area of the flow passage aperture of the valve 20, and the flow area increases as the valve is opened from closed to open. At the stage of 0-30% opening degree, along with the increase of the opening degree, the increase of the flow area is slower, and the adjusting precision of the valve can be effectively increased. At the stage of 30% -80% opening, the flow area increases faster as the opening increases. At the stage of 80% -100% opening, the increase of the flow area is slow. Naturally, in order to meet the requirement of the equal percentage curve, the actuator is required to calculate and adjust the opening of the valve, and finally the inherent flow curve of the valve is close to the equal percentage curve.

Please further refer to fig. 5 and fig. 6, wherein fig. 5 is an exploded view of the actuator assembly, and fig. 6 is a schematic view of the temperature balance valve of the internet of things partially cut through the housing of the actuator.

In this embodiment, the housing 12 of the actuator 10 is formed by enclosing the upper cover 122 and the lower housing 121, the upper case plate 13 is fixed to the lower housing 121 by engaging, and a cavity 1212 for accommodating the gear train 14 is formed therebetween; the motor 15 is engaged and fixed to the upper case plate 13, and the circuit board 11 is disposed above the motor 15 and engaged and fixed to the upper case plate 13. In the case of disposing the NFC sub-circuit board, the sub-circuit board may be disposed above the main circuit board 11, and may be connected to the main circuit board 11 through a plug. It should be understood that the components can be fixed by different plastic buckles and bayonet structures, and those skilled in the art can reasonably set the components based on the design requirements of effective utilization of the internal space and compactness, so that the details are not described herein.

The upper cover 122 and the lower shell 121 are preferably welded together by ultrasonic welding, so that the actuator 10 is waterproof and foreign-matter-proof, and the overall protection level is improved.

On this basis, the protruding end of the output gear shaft 141 is provided with the pointer 16 that coaxially rotates, and accordingly, the surface of the housing 12 (lower housing 121) is provided with the scale markings 1213. With the arrangement, after the valve core 22 is adjusted in place, the pointer 16 rotates synchronously with the valve core 22, the valve rod 21 and the output gear shaft 141, and corresponding scales are centered, so that a user can conveniently and visually read current valve flow parameters. The first mounting surface 232 and the second mounting surface 1211 are both provided in two sets symmetrically with respect to the valve stem 21, and the pointer 16 and the scale markings 1213 are located between the two sets of the first mounting surface 232 and the second mounting surface 1211.

In addition, the pointer 16 has an annular mounting portion 161 fitted to the overhanging end of the output gear shaft 141, and a circumferential stopper pair is provided between the annular mounting portion 161 and the overhanging end so that they rotate coaxially.

As shown in fig. 8, the annular mounting portion 161 is provided with a protrusion 162, and correspondingly, the output gear shaft 141 is provided with a groove 1412, wherein the protrusion 162 of the pointer 16 is placed in the groove 1412 of the output gear shaft 141 to establish a circumferential limiting pair, thereby achieving the purpose of synchronous rotation of the pointer 16 and the output gear shaft 141.

In addition, the lower housing 121 is provided with a cable mounting hole 1214, so that when the actuator 10 is vertically installed, the condensed water on the surface of the actuator 10 can be ensured not to enter the interior thereof, and further the influence of the condensed water on the normal working environment of the internal components can be avoided. The board edge of the upper box plate 13 is correspondingly provided with a U-shaped cable clamping groove 131, and the cable 17 sequentially passes through the cable penetrating hole 1214 on the lower shell 121 and the U-shaped cable clamping groove 131 on the upper box plate 13 and is connected with the circuit board 11 through the plug 171 on the cable. Specifically, a gland 18 is disposed in the cable insertion hole 1214 to fix the cable 17 and form a good seal; moreover, the groove width of the U-shaped cable clamping groove 131 gradually increases from inside to outside, that is, the U-shaped cable clamping groove 131 is respectively provided with a plurality of adaptive groove widths according to different wire diameters of different cables 17, so that different thick and thin cables can be stably fixed, and the U-shaped cable clamping groove has better adaptability.

Here, the water supply switch valve 91 and the water return regulating valve 92 may both adopt the internet of things temperature balance valve as described above; specifically, the water supply switch valve 91 is electrically and communicatively connected to the water return regulating valve 92 via an internal cable 93, and the water return regulating valve 92 is electrically and communicatively connected to an external control system 95 via an external cable 94.
