Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and more specifically, it relates to a valve with signal feedback. Background Technology

[0002] As a component of fluid control, the real-time monitoring of the opening and closing status of valves is crucial for system operation. With the continuous improvement of the intelligence and automation of production processes, it is necessary to control the working status of valves.

[0003] In industrial production processes, pipeline systems are complex and there are numerous valves. Operators find it difficult to monitor the actual opening and closing status of each valve in real time, and manual inspection is required to confirm the valve status. Existing ball valves on the market mainly focus on fluid on / off control, and the valve is opened and closed by operating the handle. Although signal valves have signal feedback functions, their applicable scenarios are limited and their costs are relatively high, making it difficult to replace conventional valves on a large scale. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a valve with signal feedback, thereby solving the technical problem that traditional valves lack signal feedback function and require manual inspection to confirm valve status, resulting in a lack of convenience.

[0005] The purpose and function of this utility model of a valve with signal feedback are achieved by the following specific technical means:

[0006] A valve with signal feedback includes a valve body, and a switch handle is rotatably mounted on the top of the valve body.

[0007] One end of the switch handle is provided with a valve body limiting protrusion, and the top of the valve body is provided with an opening limiting block and a closing limiting block corresponding to the valve body limiting protrusion. A switch feedback component is provided on one side of the valve body limiting protrusion.

[0008] The switch feedback assembly includes a valve opening signal feedback device and a valve closing signal feedback device. A mounting block is provided on one side of the valve body limiting protrusion. First mounting slots are provided on both sides of the mounting block. One set of first mounting slots corresponds to the opening limiting block and the valve opening signal feedback device is installed thereon. The other set of first mounting slots corresponds to the closing limiting block and the valve closing signal feedback device is installed thereon.

[0009] According to a preferred embodiment, the switch feedback component further includes a wireless module. A second mounting slot is provided on the top of the mounting block, and a battery is disposed in the second mounting slot. A top cover is provided at the opening of the second mounting slot, and the wireless module is disposed on the top of the top cover. The battery, the valve opening signal feedback device, and the valve closing signal feedback device are all electrically connected to the wireless module.

[0010] According to a preferred embodiment, protective covers are provided on both sides of the top cover, and the valve opening signal feedback device and the valve closing signal feedback device are respectively located in the two sets of protective covers. Both sets of protective covers are fixedly connected to the mounting block by screws.

[0011] According to a preferred embodiment, a charging plug is provided on one side of the battery, and a slot is opened on one side of the top cover corresponding to the charging plug, through which the charging plug passes.

[0012] The top of the cover is equipped with a protective shield, and the wireless module is located inside the protective shield.

[0013] According to a preferred embodiment, a rotating hole is provided on one side of the mounting block, a rotating rod is rotatably disposed in the rotating hole, a screw is provided at one end of the rotating rod, a threaded hole is provided on one side of the valve body limiting protrusion, and the screw is rotatably connected to the threaded hole.

[0014] According to a preferred embodiment, the valve body limiting protrusion has two sets of guide holes on one side, and the mounting block has two sets of guide posts on one side corresponding to the two sets of guide holes, and the two sets of guide posts are slidably inserted into the two sets of guide holes respectively.

[0015] According to a preferred embodiment, a rotating knob is provided at the end of the rotating rod away from the screw, and rotating blocks are provided on both sides of the rotating knob. A through groove is provided on one set of the rotating blocks, and a locking rod is slidably inserted in the through groove. A plurality of locking grooves are provided on one side of the mounting block corresponding to the locking rod, and one end of the locking rod is inserted in one set of the locking grooves.

[0016] A spring is provided around the locking rod, and one end of the spring is in contact with one of the sets of rotating blocks.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a switch feedback component, the valve body limiting protrusion at one end of the switch handle cooperates with the opening limiting block and closing limiting block on the valve body to achieve physical positioning when the valve reaches the fully open or fully closed position. At the same time, the valve opening signal feedback device and the valve closing signal feedback device in the first mounting groove on both sides of the mounting block can detect the opening or closing status of the valve respectively. When the valve body limiting protrusion rotates with the switch handle to contact the opening limiting block or the closing limiting block, it triggers the valve opening signal feedback device or the valve closing signal feedback device to transmit a signal to the wireless module, which then transmits the signal to the monitoring terminal. This allows operators to remotely monitor the actual opening and closing status of the valve without being physically present on-site, solving the problem of lag in traditional valve inspections that rely on manual inspections, reducing labor costs, and improving management efficiency.

[0019] 2. The mounting block is rotatably connected to the threaded hole on the valve body limiting protrusion via a screw on one side. Simultaneously, two sets of guide pins and guide holes provide positioning. Operators can adjust the mounting block position by rotating a knob, aligning the valve opening signal feedback device and valve closing signal feedback device with the opening and closing limiting blocks respectively, without requiring major modifications to the valve body. The locking rod, in conjunction with multiple locking slots, adjusts the mounting block position. The spring's elasticity ensures a tight engagement between the locking rod and the locking slots, guaranteeing the mounting block's positional stability and enhancing compatibility. The installation process is simple and efficient, allowing modifications to be completed without affecting the normal operation of the valve.

[0020] 3. By setting up two sets of protective covers, the valve opening signal feedback device and the valve closing signal feedback device are protected separately, preventing them from being subjected to external impacts. The protective cover on the top of the top cover further isolates the wireless module, improving its anti-interference capability and ensuring the stability of signal transmission. The battery is set in the second mounting slot and can be conveniently charged through the charging plug, eliminating the need for frequent battery replacements and ensuring continuous power supply to the device.

[0029] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0030] Example:

[0031] As attached Figure 1 To be continued Figure 6 As shown:

[0032] This utility model provides a valve with signal feedback, including a valve body 11, and a switch handle 12 rotatably mounted on the top of the valve body 11. The operator can open or close the valve body 11 by applying force to rotate the switch handle 12.

[0033] A valve body limiting protrusion 13 is provided at one end of the switch handle 12. At the same time, an opening limiting block 14 and a closing limiting block 15 are provided on the top of the valve body 11 corresponding to the movement trajectory of the valve body limiting protrusion 13. When the operator rotates the switch handle 12, the valve body limiting protrusion 13 at one end of the switch handle 12 rotates accordingly. When the valve reaches the fully open position, the valve body limiting protrusion 13 contacts the opening limiting block 14; when the valve reaches the fully closed position, the valve body limiting protrusion 13 contacts the closing limiting block 15.

[0034] A switch feedback assembly is provided on one side of the valve body limiting protrusion 13. The switch feedback assembly includes a valve opening signal feedback device 21 and a valve closing signal feedback device 22. A movable mounting block 23 is provided on one side of the valve body limiting protrusion 13. The mounting block 23 has first mounting grooves 24 on both sides. One set of first mounting grooves 24 corresponds to the opening limiting block 14 and installs the valve opening signal feedback device 21. The other set of first mounting grooves 24 corresponds to the closing limiting block 15 and installs the valve closing signal feedback device 22. The valve opening signal feedback device 21 and the valve closing signal feedback device 22 can both be selected from micro switches, proximity switches, photoelectric switches, Hall switches, and reed switches. When the operator rotates the switch handle 12, causing the valve body limiting protrusion 13 to rotate with the switch handle 12 to contact the opening limiting block 14, the valve opening signal feedback device 21 at the corresponding position will be triggered. When the valve body limiting protrusion 13 rotates to contact the closing limiting block 15, the valve closing signal feedback device 22 will be triggered. Therefore, the valve opening signal feedback device 21 and the valve closing signal feedback device 22 in the first mounting slots 24 on both sides of the mounting block 23 can detect the opening or closing status of the valve respectively, which changes the traditional valve reliance on manual inspection, reduces the lag problem caused by manual inspection, lowers labor costs, and improves management efficiency.

[0035] The switch feedback component also includes a wireless module 25. A second mounting slot 26 is provided on the top of the mounting block 23, and a battery 27 is placed in the second mounting slot 26 to provide power support for the entire signal feedback system. A top cover 28 is provided at the opening of the second mounting slot 26, and the wireless module 25 is fixedly installed on the top of the top cover 28. The battery 27, the valve opening signal feedback device 21, and the valve closing signal feedback device 22 are all electrically connected to the wireless module 25 through wires. When the valve opening signal feedback device 21 or the valve closing signal feedback device 22 is triggered, it will transmit the detected valve status signal to the wireless module 25. The wireless module 25 will then transmit it to the monitoring terminal via WiFi or 5G, so that the operator can remotely monitor the actual opening and closing status of the valve in real time without having to go to the valve site, which facilitates centralized management and control of the valve.

[0036] Please see as follows Figure 4 and Figure 5 As shown, protective covers 30 are installed on both sides of the top cover 28 by bolts. The valve opening signal feedback device 21 and the valve closing signal feedback device 22 are respectively located in the two sets of protective covers 30. By setting two sets of protective covers 30, the valve opening signal feedback device 21 and the valve closing signal feedback device 22 can be protected respectively. During the use of the valve, external impacts such as collisions and squeezing of external objects can be avoided from damaging the valve opening signal feedback device 21 and the valve closing signal feedback device 22, thus ensuring the normal working performance and service life of the signal feedback device.

[0037] A charging plug 31 is provided on one side of the battery 27, and a slot 32 is provided on one side of the top cover 28 corresponding to the charging plug 31. The charging plug 31 can pass through the slot 32 to connect to an external charging device, so that when the battery 27 is low in power, there is no need to disassemble and replace the battery 27. The battery 27 can be charged directly through an external charging device, ensuring the continuous power supply of the device and maintaining the stable operation of the valve signal feedback system.

[0038] In addition, a protective cover 33 is provided on the top of the top cover 28, and the wireless module 25 is located inside the protective cover 33. The protective cover 33 can isolate the influence of interference on the wireless module 25, improve the anti-interference capability of the wireless module 25, ensure the stability of the wireless module 25 in the process of receiving and transmitting valve status signals, and avoid signal loss or transmission errors.

[0039] Please see as follows Figure 5 and Figure 6 As shown, please refer to the following: Figure 5 and Figure 6 As shown, a rotating hole 34 is provided on one side of the mounting block 23, and a rotating rod 35 is rotatably installed in the rotating hole 34. A screw 36 is fixedly connected to one end of the rotating rod 35. At the same time, a threaded hole is provided on one side of the valve body limiting protrusion 13, and the screw 36 and the threaded hole are rotatably connected by thread engagement. In addition, two sets of guide holes 37 are provided on one side of the valve body limiting protrusion 13, and two sets of guide posts 38 are provided on one side of the mounting block 23 corresponding to the two sets of guide holes 37 by welding connection. The two sets of guide posts 38 are slidably inserted into the two sets of guide holes 37 respectively.

[0040] Mounting block 23 is rotatably connected to the threaded hole on valve body limiting protrusion 13 via screw 36 on one side. At the same time, the cooperation of two sets of guide pins 38 and guide holes 37 plays a positioning role. During installation or adjustment, the operator can rotate the rotating knob 39 at the end of the rotating rod 35 to drive the screw 36 to rotate in the threaded hole, thereby adjusting the position of mounting block 23 so that valve opening signal feedback device 21 and valve closing signal feedback device 22 correspond to opening limit block 14 and closing limit block 15 respectively. This structure does not require large-scale modification of valve body 11. The installation and position calibration of the switch feedback component can be achieved through simple installation and adjustment operations.

[0041] Please see as follows Figure 6As shown, a rotary knob 39 is fixedly connected to the end of the rotating rod 35 away from the screw 36. Rotating blocks 40 are welded to both sides of the rotary knob 39. One set of rotating blocks 40 has a through groove, and a locking rod 41 is slidably inserted in the through groove. Multiple locking slots 42 are opened on one side of the mounting block 23 corresponding to the locking rod 41. Two sets of inclined surfaces are provided at one end of the locking rod 41. When adjusting the position of the mounting block 23, rotating the rotary knob 39 causes the locking rod 41 to overcome the elastic force of the spring 43 and disengage from the locking slot 42 under the action of the two sets of inclined surfaces. After adjusting the mounting block 23 to the appropriate position, the locking rod 41 will connect with one set of locking slots 42 under the action of the spring 43, fixing the position of the mounting block 23. This structure can adjust the position of the mounting block 23 according to the actual situation of different valves, enhances the compatibility of the switch feedback component with different valves, and the installation process is simple and efficient, and the modification can be completed without affecting the normal use of the valve.

[0042] A spring 43 is sleeved around the locking rod 41. One end of the spring 43 contacts one of the rotating blocks 40. In its natural state, the elastic force provided by the spring 43 makes the locking rod 41 tightly engaged with the locking groove 42. Even if the valve is subjected to external forces such as vibration during use, the elastic force of the spring 43 can ensure that the locking rod 41 will not easily come out of the locking groove 42, thereby improving the positional stability of the mounting block 23.

Many modifications and variations will be apparent to those skilled in the art.
