Embodiments of this application are given in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0032] Embodiment 1:

[0033] Reference Figures 1-7, this embodiment provides a valve controller applied to heat metering. This valve controller is more convenient for staff to analyze and judge the operating conditions. Specifically, it includes a valve 1, a controller housing 2, a speed reducer 3, a control board 4, and two slide bars 6. The controller housing 2 includes an upper housing 21 and a lower housing 22. The control board 4 is fixedly connected to the top inner wall of the upper housing 21 through a plurality of bolts. The control board 4 is provided with a wireless transmission module for realizing wireless communication with an external heat meter and controlling the speed reducer 3. The upper housing 21 and the lower housing 22 are fixedly connected by bolts. The bottom surface of the lower housing 22 is fixedly connected with a connecting piece 23. The connecting piece 23 is fixedly connected to the valve 1 through a plurality of bolts. The inner cavity of the connecting piece 23 is hollow-designed. Inspection openings 220 are respectively formed through the left and right sides of the lower housing 22 near the bottom surface. Protrusions 221 are integrally formed at the bottom of the inner wall of the lower housing 22 near the corners. An RF connector for signal transmission and reception is also installed on the surface of the lower housing 22. The speed reducer 3 is installed on the top surfaces of a plurality of protrusions 221 through a plurality of bolts. The specific model of the speed reducer 3 is LSR042-L1. The output end of the speed reducer 3 is fixedly connected with a control rod 5. The control rod 5 vertically passes through the bottom surface of the lower housing 22 and is mutually clamped with the valve 1 through the inner cavity of the connecting piece 23. A protrusion 51 located inside the lower housing 22 is fixedly connected to the surface of the control rod 5. The protrusion 51 is designed with an elliptical structure;

[0034] Reference Figures 3-5 , the two slide bars 6 are respectively inserted into the two inspection openings 220 in a horizontally transverse movable manner. A first baffle 61 is integrally formed on the surface of the slide bar 6 in a circular shape. Both of the two first baffles 61 are located inside the lower housing 22. Springs 7 are sleeved outside the slide bars 6. The two springs 7 are respectively located between the two first baffles 61 and the left and right sides of the inner wall of the lower housing 22. One end of the slide bar 6 is designed in a semi-circular shape. The semi-circular end of the slide bar 6 is in contact with the convex surface of the protrusion 51. The surfaces of the protrusion 51 and the slide bar 6 are both set as smooth surfaces, so that during the running rotation of the output end of the speed reducer 3 installed in the controller housing 2, the protrusion 51 can be driven to rotate simultaneously, and through the cooperation of the protrusion 51 with the slide bar 6 and the spring 7; the slide bar 6 can change its position relative to the controller housing 2 under the action of the spring 7 along with the rotation of the protrusion 51, so as to facilitate the staff to judge the operating conditions of the speed reducer 3 located inside the controller housing 2 according to the position change of the slide bar 6; it is convenient to determine whether the speed reducer 3 is in a normal operating state during the troubleshooting of the steam supply system without disassembling and inspecting the controller housing 2.

[0035] Such as Figures 1-6As shown in the figure, in this embodiment, recessed grooves 222 are provided on both the left and right sides of the lower housing 22 and near the inspection opening 220. One end of the sliding rod 6 is provided with an indicator plate 62, and the indicator plate 62 is slidably arranged in the recessed groove 222. The sliding fit between the indicator plate 62 and the recessed groove 222 can be effectively utilized to achieve the limiting effect on the sliding rod 6. When the protrusion 51 rotates with the control rod 5 and moves away from the sliding rod 6, the indicator plate 62 enters the recessed groove 222, and the lower housing 22 is used to achieve the limiting effect on the sliding rod 6, avoiding the situation that the sliding rod 6 enters the controller housing 2 due to the rebound of the spring 7.

[0036] As Figures 1-4 shown in the figure, in this embodiment, a sleeve one 223 is integrally formed on both the left and right sides of the lower housing 22 and near the inspection opening 220. The inner diameter of the sleeve one 223 is adapted to the diameter of the indicator plate 62, and the indicator plate 62 is located in the inner cavity of the sleeve one 223. The position fit between the sleeve one 223 and the indicator plate 62 can be effectively utilized to achieve the protection effect on the recessed groove 222, avoiding foreign objects from entering the recessed groove 222.

[0037] As Figures 3-6 shown in the figure, in this embodiment, a sleeve two 611 is fixedly connected to one side of the baffle one 61, and the sleeve two 611 is located inside the spring 7, making the spring 7 more stable on the outside of the sliding rod 6.

[0038] As Figures 1-5 shown in the figure, in this embodiment, a limiting frame 2211 is fixedly connected to the surface of the convex block 221. The limiting frame 2211 is designed in an "L" shape. The speed reducer 3 is located between multiple limiting frames 2211. Two baffle plates three 8 are fixedly connected to the side surface of the connecting piece 23. The baffle plates three 8 are designed in an arc shape. The concave surfaces of the two baffle plates three 8 are in contact with the outer side surface of the valve 1, so as to effectively achieve the position limiting effect on the speed reducer 3 and the connecting piece 23, and thus be more conducive to the fixed installation between the speed reducer 3 and the convex block 221 and between the connecting piece 23 and the valve 1.

[0039] Embodiment 2:

[0040] As Figures 8-9As shown in the figure, this embodiment provides a heating system, which includes the valve 1 controller described in Embodiment 1, and also includes a steam supply pipeline 93, a heat meter 91 and a control module 9. The steam supply pipeline 93 is used to convey heating, and the heat meter 91 is used for heat measurement; the valve 1 is arranged on the steam supply pipeline 93, and the valve 1 controller is connected to the valve 1; the heat meter 91 is arranged on the steam supply pipeline 93, and the heat meter 91, the valve controller 92 and the control module 9 are physically connected; the heat meter 91 sends the measured data to the control module 9, and the control module 9 sends a control signal to the valve 1 controller; the heat meter 91 is used to monitor the heating delivery volume in real time and realize data feedback with the remote controller, so as to realize the control effect on the valve 1 controller by using the monitoring data.

[0041] During the process of troubleshooting the heating system, if there is a phenomenon of heating interruption or slow heating in the heating system, the staff can observe and judge the position between the sliding rod 6 and the controller housing 2. If the indicating plate 62 at one end of the sliding rod 6 protrudes outside the recessed groove 222 opened in the controller housing 2, it means that the valve 1 is always in the open state, and the situation of the reducer 3 malfunction can be excluded. If the heating system continues to supply heat due to the user's heating cost being overused, and the sliding rod 6 is still in the above state, it means that there is a malfunction in the reducer 3, which is more conducive to the staff's troubleshooting operation.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
