Description

Technical Field

[0001] The utility model relates to the technical field of intelligent valves, in particular to an intelligent valve control opening and closing structure. Background Art

[0002] Valves are control components in fluid delivery systems. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are equipped with opening and closing elements for cutting off or connecting the media. The opening and closing elements are usually used in conjunction with a handwheel to open or close the valve. After searching, the prior art (application number: CN201621141591.5) records "a water-saving electromagnetic valve, including a pipeline, a valve core, a touch display screen and an electromagnetic valve, a water inlet is provided in the middle of the lower surface of the pipeline, and the right and left water outlets are symmetrically provided at both ends of the pipeline, a temperature monitor, a valve core and a piston are provided inside the pipeline, and an electromagnetic valve is provided in the middle of the upper surface of the pipeline, a valve core and an electromagnetic valve cover are provided inside the electromagnetic valve, and a prompt device is provided in the middle of the upper surface of the electromagnetic valve, a touch display screen is provided on the outer surface of the electromagnetic valve, and a power-on hole is provided on one side of the outer surface of the electromagnetic valve. The water-saving electromagnetic valve has a simple structure and is easy to operate. The temperature of the water in the water heater is sensed by the temperature detector and the prompt device. When the water temperature is too high, the electromagnetic valves control the water outlet to discharge water, thereby avoiding the discharge of a large amount of cold water during daily use of hot water, causing waste of water resources, and achieving the effect of energy saving and environmental protection."

[0003] However, although the smart valves in the prior art are easy to install, transport and store, they still have some shortcomings: the existing solenoid valves generally only have the function of quick opening and closing, and cannot achieve the effect of adjusting the flow rate by controlling the valve stem stroke, resulting in limited use. At the same time, they do not have the dual effects of on-site operation and remote control, resulting in poor functionality. Utility Model Content

[0004] In order to overcome the defects of the prior art, an intelligent valve control opening and closing structure is now provided to solve the problems of limited use and poor functionality of the existing electromagnetic valves.

[0005] To achieve the above-mentioned purpose, an intelligent valve control opening and closing structure is provided, including: a valve seat, an outer shell and a sealing box, the outer shell is connected to the upper end of the valve seat, and a control unit is provided on the outer wall of the outer shell, and a coil is provided on the inner side of the outer shell, a first iron core is provided on the inner side of the coil, and the lower end of the first iron core is connected to an opening and closing assembly through a spring, an electric push rod is provided inside the sealing box, and the lower end of the electric push rod is connected to a slide plate, and the lower end of the slide plate is connected to a driving rod, and the lower end of the driving rod is connected to the first iron core.

[0006] Furthermore, a pressure sensor is installed on the outer wall of the valve seat, and the pressure sensor is electrically connected to the coil through a control unit.

[0007] Furthermore, the opening and closing assembly includes a slip ring slidably connected to the inside of the shell, and the lower end of the slip ring is connected to the second iron core, and the outer wall of the slip ring is provided with a sealing ring.

[0008] Furthermore, the opening and closing assembly also includes a valve stem connected to the lower end of the second iron core, and the valve stem is inserted into a valve port opened inside the valve seat.

[0009] Furthermore, the first iron core is slidably connected to the inner side of the coil, and the driving rod slides through the top of the shell and is connected to the first iron core.

[0010] Furthermore, the slide plate is slidably connected inside the sealing box, the electric push rod is connected to the middle part of the upper side of the slide plate, and the base of the electric push rod is fixed to the upper inner wall of the sealing box.

[0011] Furthermore, a communication module and an encoder are provided inside the control unit, and the control unit includes a shell arranged outside, and a control button is provided on the outer wall of the shell.

[0012] The beneficial effects of the utility model are:

[0013] 1. When the electromagnetic valve is used as a basic opening and closing function, the first iron core is at the highest position. When the coil is powered on and off by the manual operation button or the remote device terminal, the second iron core moves. Specifically, the coil is powered on to move the second iron core upward toward the first iron core, so that the valve stem can be moved up to open the valve port. After the power is off, the second iron core moves downward under the action of the spring to block the valve port again, achieving the basic rapid opening and closing effect, thereby realizing the dual use functionality of on-site or remote control;

[0014] 2. When it is necessary to adjust the pipeline flow, the outer button and control unit are used to drive the electric push rod to move, and the first iron core is moved downward for a certain stroke. The stroke size can be set according to the flow control needs. Multiple strokes can be set using the encoder. After the electric push rod is actuated, the coil is set to be energized with a delay, thereby driving the valve stem to move upward through the second iron core. At this time, the valve stem is not completely separated from the valve port, thereby achieving a current limiting effect. By setting multiple strokes, different degrees of current limiting effects can be obtained, thereby increasing the wide range of uses.

[0015] 3. A pressure sensor is provided in the pipeline of the valve seat, so that when the medium leaks inside the pipeline, the internal pressure change is detected by the pressure sensor, and then the coil is energized by the control unit, thereby achieving the effect of quickly closing the pipeline.

[0021] Reference Figures 1 to 4 As shown, the utility model provides an intelligent valve control opening and closing structure, including: a valve seat 1, a shell 2 and a sealing box 3, the shell 2 is connected to the upper end of the valve seat 1, and a control unit 21 is provided on the outer wall of the shell 2, and a coil 23 is provided on the inner side of the shell 2, a first iron core 22 is provided on the inner side of the coil 23, and an opening and closing component 25 is connected to the lower end of the first iron core 22 through a spring 24, an electric push rod 31 is provided inside the sealing box 3, and a slide plate 32 is connected to the lower end of the electric push rod 31, and a driving rod 33 is connected to the lower end of the slide plate 32, and the lower end of the driving rod 33 is connected to the first iron core 22, and the slide plate 32 is slidably connected inside the sealing box 3, and the electric push rod 31 is connected to the middle part of the upper side of the slide plate 32, and the base of the electric push rod 31 is fixed to the upper inner wall of the sealing box 3.

[0022] In this embodiment, the valve seat 1, the outer shell 2, the sealing box 3 and the internal structure constitute the intelligent valve control opening and closing structure involved in this application.

[0023] Specifically, the control unit 21 is provided with a battery inside and a power socket outside for flexible power supply.

[0024] Specifically, two parallel driving rods 33 are provided.

[0025] like Figure 1 and Figure 3In the embodiment, a pressure sensor 11 is installed on the outer wall of the valve seat 1, and the pressure sensor 11 is electrically connected to the coil 23 through the control unit 21. The opening and closing component 25 includes a slip ring 251 slidably connected to the inside of the shell 2, and the lower end of the slip ring 251 is connected to the second iron core 253, and the outer wall of the slip ring 251 is provided with a sealing ring 252. The opening and closing component 25 also includes a valve stem 254 connected to the lower end of the second iron core 253, and the valve stem 254 is inserted into the valve port opened in the valve seat 1.

[0026] As a preferred implementation, the pressure sensor 11 facilitates intelligent detection and the effect of closing the valve, thereby improving the immediacy of pipeline leakage protection.

[0027] Specifically, the slip ring 251 is only disposed on the upper end of the second iron core 253 , and the second iron core 253 penetrates and is inserted into the interior of the slip ring 251 .

[0028] Specifically, the lower end of the valve stem 254 is provided with a blocking end with a conical structure.

[0029] It should be noted that the positional relationship between the first iron core 22 and the second iron core 253 and the coil 23 is consistent with the moving iron core and the static iron core involved in the direct-acting electromagnetic valve in the prior art, except that the static iron core is set to an adjustable state in this application.

[0030] like Figure 1 and Figure 4 In the embodiment, the first iron core 22 is slidably connected to the inner side of the coil 23, and the driving rod 33 slides through the top of the shell 2 and is connected to the first iron core 22. A communication module and an encoder are provided inside the control unit 21, and the control unit 21 includes a shell arranged on the outside, and a control button is provided on the outer wall of the shell.

[0031] Specifically, the electric push rod 31 is pre-set by an encoder to achieve multiple stroke adjustments, thereby facilitating the control of the opening position change of the valve stem 254.

[0032] Specifically, the communication module is configured as wireless communication to facilitate remote control.

[0033] When in use, when the electromagnetic valve is used as a basic opening and closing function, the first iron core is in the highest position at this time. When the manual operation button or the remote device terminal controls the coil to be powered on and off, the second iron core moves. Specifically, the coil is energized to move the second iron core upward toward the first iron core, so that the valve stem can be moved up to open the valve port. After power is off, the second iron core moves downward under the action of the spring to block the valve port again, thereby achieving a basic rapid opening and closing effect, thereby achieving dual-use functionality of on-site or remote control; when it is necessary to adjust the pipeline flow, at this time, the outer button and control unit are used to drive the electric push rod to move, and the first iron core is moved downward for a stroke. The stroke size can be set according to the flow control needs, and multiple strokes can be set using the encoder. After the electric push rod is actuated, the coil is set to be powered on with a delay, thereby driving the valve stem to move upward through the second iron core. At this time, the valve stem is not completely separated from the valve port, thereby achieving a current limiting effect, and by setting multiple strokes, different degrees of current limiting effects can be obtained, thereby increasing the wide range of use.

[0034] The intelligent valve control opening and closing structure of the utility model can effectively solve the problems of limited use and poor functionality of some electromagnetic valves. On the basis of the existing intelligent valve control opening and closing structure technology, the existing electromagnetic valve has the effect of adjusting the pipeline flow, and at the same time, the electromagnetic valve has intelligent remote control and a protective effect on pipeline leakage.
