Description

Technical Field

[0001] The present invention relates to the technical field of valves, and in particular to a remote control, remote sensing and remote plugging device. Background Art

[0002] With the development of industrial automation and intelligence, traditional manual or semi-automatic control valves are gradually unable to meet the requirements of modern industrial production for efficiency, safety and intelligence, especially in dangerous, harsh or difficult-to-reach working environments.

[0003] Ball valves are the most common manual or semi-automatic control valves. They contain a sphere with a hole in it that is operated by a stem. When open, the hole in the ball aligns with the pipe's channel, allowing fluid to flow. When closed, the hole in the ball no longer aligns with the pipe's flow path. Humidity is generally high in environments such as marine and coastal areas, sewage treatment plants, and agricultural irrigation systems. Existing ball valves lack automatic dehumidification capabilities. Moisture in high-humidity environments combines with oxygen in the air, causing oxidation reactions on valve surface materials (such as steel and aluminum alloys), leading to corrosion and rust. Moisture, in particular, accelerates the oxidation process of materials like steel and cast iron in metal valves, potentially causing valve failure in severe cases. Furthermore, valve sealing components (such as rubber and polytetrafluoroethylene) are susceptible to moisture absorption in high-humidity environments, causing the sealing material to swell, deform, or degrade, compromising the valve's sealing performance. Prolonged exposure to moisture can weaken and lose its elasticity, increasing the risk of leakage. Therefore, dehumidification is crucial to valve life. Furthermore, when a ball valve is closed, the hole in the ball no longer aligns with the flow path in the pipe. Consequently, the fluid is isolated on either side of the valve, trapping the medium within the valve cavity where it can easily accumulate, shortening the valve's service life. Traditional valve control methods also suffer from complex operation, slow response, and difficulty in remote monitoring. Therefore, remote-controlled, remote-sensing, and remote-blocking valves have emerged, offering the advantages of remote control, monitoring, and dehumidification. Summary of the Invention

DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] Example 1, as Figures 1-8 As shown, a remote control, remote sensing and remote plug device includes a valve body 1, an outer ball valve 2 is rotatably installed inside the valve body 1, an inner ball valve 3 is rotatably installed inside the outer ball valve 2, a liquid inlet stopper 23 is provided on the left side of the valve hole of the outer ball valve 2, and a plurality of groups of liquid inlets are provided in an annular manner inside the liquid inlet stopper 23. A slide rod 24 is slidably connected to the interior of the liquid inlet stopper 23. The slide rod 24 is T-shaped. A top block 25 is provided on the side of the slide rod 24 close to the interior of the outer ball valve 2. A plurality of groups of sealing sheets 26 are provided on the side of the top block 25 close to the liquid inlet stopper 23. The sealing sheets 26 can block the liquid inlets.

[0031] An external guide hole 12 is provided at the bottom of the valve body 1, an internal guide hole 22 is provided at the bottom of the outer ball valve 2, a remote sensing module 7 is installed on the top of the valve body 1, and a fan 8 is fixedly installed at the bottom of the valve body 1, and the fan 8 is connected to the external guide hole 12 and the internal guide hole 22. An external electromagnetic exhaust valve 14 is provided on the outside of the valve body 1, and the outer ball valve 2 is connected to the outside through the internal electromagnetic exhaust valve 52.

[0032] The data inside and outside the valve are collected through the remote sensing module 7. When the humidity inside and outside the valve is too high, the valve dehumidification function is started by remote control. At this time, the inner ball valve 3 is controlled to rotate relative to the outer ball valve 2. When the inner ball valve 3 rotates, it will push the top block 25 to move toward the liquid inlet block 23. The top block 25 pushes the sealing piece 26 to seal the liquid inlet to achieve preliminary sealing. At this time, the liquid inlet end of the valve hole of the outer ball valve 2 is isolated from the pipeline, and the liquid outlet end of the valve hole of the inner ball valve 3 is still connected to the liquid outlet end of the valve. The medium inside the inner ball valve 3 will be discharged through the outlet, and then the inner ball valve 3 is controlled to continue to rotate. When the inner ball valve 3 rotates 90 degrees, it stops rotating. The inner ball valve 3 seals the outer ball valve 2 for the second time to ensure that both ends of the outer ball valve 2 are blocked. At the same time, the fan 8 sends wind into the valve body 1 through the outer guide hole 12 When the outer ball valve 3 is rotated 90 degrees, the valve still remains in a blocked state, and the moisture in the valve body 1 is completely brought out. After the dehumidification of the outer ball valve 2 is completed, the outer ball valve 2 is controlled to rotate 90 degrees so that the valve hole is perpendicular to the flow direction of the pipeline. At this time, the fan 8 sends wind into the cavity inside the outer ball valve 2 through the inner guide hole 22, and the inner electromagnetic exhaust valve 52 is opened, and the air circulates inside the outer ball valve 2 to bring out the internal moisture. The inner ball valve 3 is controlled to rotate 90 degrees, and the valve still remains in a blocked state, and the dehumidification effect is good. Therefore, the setting of the double-core ball valve of the present invention can completely dehumidify the inside of the valve without affecting the blocking of the valve.

[0033] It should be noted that, since the present invention needs to achieve the effect of gas circulation between the valve body 1 and the outer ball valve 2, there needs to be a distance between the valve body 1 and the outer ball valve 2, and between the outer ball valve 2 and the inner ball valve 3. This will cause more medium to accumulate in the valve body 1 and the outer ball valve 2. Therefore, the valve of the present invention is different from the existing valve in normal opening and closing logic. It is necessary to first control the inner ball valve 3 to rotate relative to the outer ball valve 2. When the inner ball valve 3 rotates, it will push the top block 25 to move toward the liquid inlet stopper 23. The top block 25 pushes the sealing plate 26 to block the liquid inlet. Through the design of the special structure of the top block 25 itself, as shown in the attached figure Figure 6 In the state shown, the inner ball valve 3 only needs to rotate a small angle to achieve preliminary blocking, and the right end of the valve hole of the inner ball valve 3 (that is, the end close to the outlet) is not connected to the cavity inside the outer ball valve 2, and the medium will not enter the outer ball valve 2. At this time, the liquid inlet end of the valve hole of the outer ball valve 2 is isolated from the pipeline, and the liquid outlet end of the valve hole of the inner ball valve 3 is still connected to the liquid outlet end of the valve. The medium inside the inner ball valve 3 will be discharged through the outlet. Therefore, when closed, no medium will enter the valve body 1 and the outer ball valve 2, thereby improving the service life of the valve.

[0034] Embodiment 2, based on the above embodiment, further includes: two groups of outer sealing rings 11 are provided inside the valve body 1, and the two groups of outer sealing rings 11 are respectively sealed and sleeved on the two ends of the outer ball valve 2, and two groups of inner sealing rings 27 are provided inside the outer ball valve 2, and the two groups of inner sealing rings 27 are respectively sleeved on the two ends of the inner ball valve 3, and the contact area between the inner sealing ring 27 and the inner ball valve 3 is greater than the contact area between the outer sealing ring 11 and the outer ball valve 2.

[0035] The structural design of the inner sealing ring 27 can better ensure that when the initial seal is achieved, the right end of the valve hole of the inner ball valve 3 (that is, the end close to the outlet) will not be connected to the cavity inside the outer ball valve 2, ensuring that the medium discharge is more stable.

[0036] Furthermore, a mounting port is provided at the bottom of the outer ball valve 2 , through which the inner ball valve 3 can pass. A valve bottom 21 is fixedly installed at the bottom of the mounting port, and an inner guide hole 22 is provided in the valve bottom 21 . The valve bottom 21 is located below the outer sealing ring 11 .

[0037] The arrangement of the valve bottom 21 facilitates the installation of the inner ball valve 3 in the outer ball valve 2 and facilitates assembly and disassembly.

[0038] Embodiment 3, on the basis of the above embodiment, further includes: a mounting base plate 13 is fixedly installed at the bottom of the outer guide hole 12, and a lifting tube 9 is sealed and slidably connected inside the mounting base plate 13. The lifting tube 9 passes through the inner guide hole 22, and a telescopic drive 10 is fixedly installed at the bottom of the lifting tube 9. The telescopic drive 10 can be an electric telescopic rod or a cylinder. A suitable drive can be selected according to the installation environment. The telescopic end of the telescopic drive 10 is fixedly installed on the mounting base plate 13, and two groups of air inlet holes 91 are opened in the upper and lower parts of the lifting tube 9. An air inlet box 81 is provided between the fan 8 and the valve body 1, and the air inlet box 81 is connected to the lifting tube 9 through an air pipe and a one-way valve.

[0039] Furthermore, a drain valve 93 is provided at the bottom of the lifting pipe 9 , and the drain valve 93 can be used to drain water or other impurities in the valve body 1 and the outer ball valve 2 .

[0040] This embodiment provides a specific air intake method. When ventilation is required inside the valve body 1, the telescopic drive 10 drives the lifting tube 9 to descend, and the lifting tube 9 is located at the lowest position. At this time, the upper air inlet hole 91 is located in the inner guide hole 22 and is blocked by the inner guide hole 22. The lower air inlet hole 91 is connected to the interior of the valve body 1. At this time, the fan 8 blows air into the air inlet box 81, and the air inlet box 81 blows air through the lifting tube 9 through the air pipe and the one-way valve. The air flow enters the valve body 1 through the lower air inlet hole 91 and is discharged through the external electromagnetic exhaust valve 14.

[0041] When it is necessary to ventilate the interior of the outer ball valve 2, the telescopic drive 10 drives the lifting pipe 9 to rise, and the lifting pipe 9 is located at the uppermost position. At this time, the upper air inlet 91 is connected to the outer ball valve 2, and the lower air inlet 91 enters the inner guide hole 22 and is blocked by the inner guide hole 22. At this time, the fan 8 blows air into the air inlet box 81, and the air inlet box 81 blows air through the air pipe and the one-way valve to the lifting pipe 9. The air flow enters the outer ball valve 2 through the upper air inlet 91 and is discharged through the inner electromagnetic exhaust valve 52.

[0042] Embodiment 4, on the basis of the above embodiment, further includes: an outer valve stem 4 is fixedly installed on the top of the outer ball valve 2, an inner valve stem 5 is fixedly installed on the top of the inner ball valve 3, the inner valve stem 5 passes through the outer valve stem 4, a transmission groove is provided on the top of the outer valve stem 4, a slide groove is provided on the inner wall of the transmission groove, a transmission wedge 41 is slidably connected inside the slide groove, a top spring is provided between the transmission wedge 41 and the inner wall of the slide groove, a transmission disk 53 is provided on the outside of the inner valve stem 5, the transmission disk 53 is inserted in the transmission groove, a sealing top plate 42 is fixedly installed on the top of the transmission groove, a plurality of groups of triangular grooves are provided in an annular shape on the outer side of the transmission disk 53, the transmission wedge 41 is inserted in the triangular groove, a remote control drive motor 6 is fixedly installed on the top of the valve body 1, the output end of the remote control drive motor 6 is connected to the inner valve stem 5, and a pressure ring 92 is provided on the outside of the lifting tube 9.

[0043] Furthermore, friction grooves are formed on the top surface of the pressure ring 92 and the bottom surface of the inner guide hole 22 to increase friction.

[0044] When the humidity inside and outside the valve is too high, the remote control starts the valve dehumidification function, controls the telescopic drive 10 to operate, and the telescopic drive 10 drives the lifting tube 9 to rise. The lifting tube 9 drives the pressure ring 92 to press on the bottom surface of the inner guide hole 22. The top pressure friction force is much greater than the elastic force of the top spring. Under the action of the friction force, the outer ball valve 2 cannot rotate. At this time, the remote control drive motor 6 is controlled to operate, and the remote control drive motor 6 drives the inner ball valve 3 to rotate relative to the outer ball valve 2. When the inner ball valve 3 rotates, it will push the top block 25 to move toward the liquid inlet stopper 23. The top block 25 pushes the sealing plate 26 to block the liquid inlet, realizing preliminary blocking. At this time, the liquid inlet end of the valve hole of the outer ball valve 2 is isolated from the pipeline, and the liquid outlet end of the valve hole of the inner ball valve 3 is still connected to the liquid outlet end of the valve. The medium inside the inner ball valve 3 will be discharged through the outlet, and then the inner ball valve 3 is controlled The valve 3 continues to rotate. When the inner ball valve 3 rotates 90 degrees, it stops rotating. The inner ball valve 3 blocks the outer ball valve 2 for the second time to ensure that both ends of the outer ball valve 2 are blocked. The telescopic drive 10 drives the lifting pipe 9 to descend. The lifting pipe 9 is at the lowest position. At this time, the upper air inlet 91 is located in the inner guide hole 22 and is blocked by the inner guide hole 22. The lower air inlet 91 is connected to the interior of the valve body 1. At this time, the fan 8 blows air into the air inlet box 81. The air inlet box 81 blows air through the air pipe and the one-way valve to the lifting pipe 9. The air flow enters the valve body 1 through the lower air inlet 91 and is discharged through the outer electromagnetic exhaust valve 14. The air circulates inside the valve body 1 and brings out the internal moisture. At this time, the outer ball valve 2 can be rotated 90 degrees, and the valve still remains blocked, so the moisture in the valve body 1 can be completely brought out.

[0045] After the dehumidification of the outer ball valve 2 is completed, the outer ball valve 2 is controlled to rotate 90 degrees so that the valve hole is perpendicular to the flow direction of the pipeline, and the telescopic drive 10 is operated again. The telescopic drive 10 drives the lifting pipe 9 to rise, and the lifting pipe 9 drives the pressure ring 92 to press on the bottom surface of the inner guide hole 22. Under the action of friction, the outer ball valve 2 cannot rotate. At this time, the remote control drive motor 6 is controlled to operate, and the remote control drive motor 6 drives the inner ball valve 3 to rotate relative to the outer ball valve 2. At the same time, the lifting pipe 9 is in the uppermost position. At this time, the upper air inlet 91 is connected to the outer ball valve 2, and the lower air inlet 91 enters the inner guide hole 22 and is blocked by the inner guide hole 22. At this time, the fan 8 blows air into the air inlet box 81, and the air inlet box 81 blows air through the lifting pipe 9 through the air pipe and the one-way valve. The air flow enters the outer ball valve 2 through the upper air inlet 91 and is discharged through the inner electromagnetic exhaust valve 52. The air inside the outer ball valve 2 circulates, bringing out the internal moisture. The inner ball valve 3 is controlled to rotate forward and backward 90 degrees, and the valve still remains in a blocked state, and the dehumidification effect is good.

[0046] Therefore, through the arrangement of this embodiment, when controlling the driving switching of the outer ball valve 2 and the inner ball valve 3, the switching of the connection of the lifting pipe 9 can also be completed at the same time, which has a compact structure and simple control.

[0047] Embodiment 5, based on the above embodiment, further includes: an air hole 51 is opened inside the inner valve stem 5, the bottom end of the air hole 51 is connected to the inside of the outer ball valve 2, an inner electromagnetic exhaust valve 52 is fixedly installed at the top of the air hole 51, and an exhaust window 15 is provided between the remote control drive motor 6 and the valve body 1.

[0048] The gas in the outer ball valve 2 is discharged to the outside through the air hole 51 and the inner electromagnetic exhaust valve 52 and will not be connected with the space of the valve body 1.

[0049] Embodiment 6, based on the above embodiments, further includes that the outer surfaces of the liquid inlet stopper 23 and the sealing plate 26 are both designed to be arcs, and the center of the arc coincides with the center of the outer ball valve 2.

[0050] Through the arrangement of this embodiment, when the sealing plate 26 blocks the liquid inlet, the end of the outer ball valve 2 close to the liquid inlet is a closed arc surface, so when the outer ball valve 2 is repeatedly rotated 90 degrees or directly closed, no excess medium will be brought into the valve body 1, the valve dehumidification will not be affected, and the medium will not accumulate in the valve body 1. The dehumidification is stable and the valve has a long service life.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
