Description

Technical Field

[0001] This utility model relates to the field of flow calibration technology, and in particular to a fluoropolymer-lined valve with a lifting structure. Background Technology

[0002] Fluorine-lined valves are valves with on / off and flow regulation functions. The valve body is lined with fluoroplastic, which has the advantages of acid and alkali resistance, corrosion resistance, wear resistance, high temperature resistance, good sealing performance, and long service life. They can be widely used in chemical, power, pharmaceutical, food and other industries.

[0003] In the existing technology, when using fluoropolymer-lined valves, the lack of corresponding anti-accidental contact locking features on the valve handle and its transmission structure means that if the exposed valve handle is accidentally touched, the valve will open, causing liquid or gas in the pipeline to flow out, resulting in a large waste of resources.

[0004] An existing patent (publication number: CN213744956U) discloses a fluoropolymer-lined valve structure with a lifting mechanism, which allows the worm gear to drive the threaded rod into the first threaded groove through the stop block under the action of the worm wheel, thereby preventing the bevel gear from rotating; by setting up an anti-accidental contact reinforcing locking mechanism, it is prevented that the exposed fluoropolymer-lined valve handle will be accidentally touched, causing the liquid or gas in the pipe to flow out, thus reducing the waste of resources.

[0005] To address the aforementioned issues, while existing patents offer solutions that can achieve a locking effect through the cooperation of components such as worm gears and worm wheels, in actual use, the worm wheel requires a relatively precise meshing method when driving the worm, and there is no situation where locking is not possible. In addition, when the threaded rod is inserted, there is a certain rotational force, which may generate thrust on the bevel gears and conical gears, resulting in loosening and affecting the opening and closing of the valve. Summary of the Invention

[0006] The purpose of this utility model is to provide a fluoropolymer-lined valve with a lifting structure, which can achieve a locking effect through the worm gear and worm wheel during the opening and closing process. While enabling remote control, it avoids the possibility of loosening due to the impact of the medium when the valve is open or closed, thereby affecting the sealing performance and use effect of the valve body, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a fluoropolymer-lined valve with a lifting structure, comprising a valve body, wherein a drive housing is fixedly installed at the top of the valve body, and a drive mechanism is provided on one side of the valve body at the bottom of the drive housing.

[0008] The drive mechanism includes a mounting housing, which is fixed to one side of the valve body at the bottom of the drive housing. An electromagnet is embedded in the bottom of the mounting housing. A rack is inserted into the interior of the mounting housing, and a permanent magnet is fixedly installed at one end of the rack. A gear is rotatably connected to the outer wall of the end of the rack that is inserted into the drive housing. A worm protrudes from the interior of the gear. A worm wheel is rotatably connected to the outer wall of the end of the worm that is inserted into the gear. A valve stem is fixedly installed at the bottom of the worm wheel, and a connecting rod is fixedly installed at the top of the worm wheel.

[0009] Preferably, a sliding rod is fixedly installed at the top of the rack, and a sleeve is embedded inside the drive housing at the position corresponding to the sliding rod.

[0010] Preferably, a limiting plate is fixedly installed on the outer wall of one end of the sliding rod that passes through the sleeve, and a spring is fixedly installed on the top of the limiting plate.

[0011] Preferably, a device housing is embedded on one side of the outer wall of the drive housing, and a photovoltaic module is embedded on the top of the device housing.

[0012] Preferably, a connecting sleeve is fixedly installed at one end of the worm gear, and a positioning mechanism is provided at the other end of the connecting sleeve.

[0013] Preferably, the positioning mechanism includes a threaded rod that extends through the inner wall of the connecting sleeve, and a sliding plate is slidably connected to the outer wall of one end of the threaded rod that extends into the connecting sleeve. A limiting groove is formed inside the sliding plate, and an abutment block is fixedly installed on one side of the limiting groove at the front end of the sliding plate.

[0014] Preferably, a slider is fixedly installed at one end of the sliding plate, and a groove is provided inside the drive housing at the position corresponding to the slider.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses the lifting control of the rack to drive the gear to rotate, and through the transmission of the worm and worm wheel, the valve stem drives the valve plate of the valve body to rotate, thereby opening and closing. During the opening and closing process, the worm and worm wheel have a locking effect. While enabling remote control, it avoids the possibility of loosening due to the impact of the medium when the valve is open or closed, which would affect the sealing performance and use of the valve body.

[0017] 2. This utility model uses the worm gear and connecting sleeve to drive the threaded rod to push the sliding plate, allowing the two abutment blocks to press the worm wheel from both sides. This prevents the worm wheel from loosening when the valve body is closed, further improving stability. When the valve body is open, the sliding plate moves away from the worm wheel to avoid mutual interference. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4A fluoropolymer-lined valve with a lifting structure includes a valve body 1. A drive housing 2 is fixedly mounted on the top of the valve body 1, and a drive mechanism 3 is provided on one side of the valve body 1 at the bottom of the drive housing 2. The drive mechanism 3 includes a mounting housing 301, which is fixed to one side of the valve body 1 at the bottom of the drive housing 2. An electromagnet 302 is embedded in the bottom of the mounting housing 301, and a rack 304 is inserted into the interior of the mounting housing 301. A permanent magnet 303 is fixedly mounted on one end of the rack 304, and the rack 304 is rotatably connected to the outer wall of one end of the drive housing 2. There is a gear 305, and a worm 306 extends through the inside of the gear 305. A worm wheel 307 is rotatably connected to one end of the worm 306 that extends through the outer wall of the gear 305. A valve stem 308 is fixedly installed at the bottom end of the worm wheel 307. A connecting rod 309 is fixedly installed at the top end of the worm wheel 307. A sliding rod 310 is fixedly installed at the top end of the rack 304. A sleeve 311 is embedded in the top end of the drive housing 2 at the position corresponding to the sliding rod 310. A limit plate 312 is fixedly installed on the outer wall of one end of the sliding rod 310 that extends into the sleeve 311. A spring 313 is fixedly installed at the top end of the limit plate 312.

[0029] By adopting the above technical solution, the electromagnet 302 inside the mounting shell 301 uses the principle of a double-pole double-throw switch to control the direction of the current in the electromagnet 302 via signal control. This allows the electromagnet 302 to push or attract the permanent magnet block 303, which in turn drives the rack 304 to push the gear 305, causing the worm gear 306 to drive the worm wheel 307 to rotate. This causes the valve stem 308 to drive the valve plate inside the valve body 1 to rotate, thus controlling the opening and closing of the valve body 1. This allows for remote control of the opening and closing of the valve body 1. The rack 304 can be adjusted in height to control the opening and closing state of the valve body 1. At the same time, the worm gear 306 and worm wheel 307 can lock the valve plate to prevent it from loosening due to the impact of the medium. With the limiting of the sleeve 311, the sliding rod 310 slides stably to maintain the stable sliding of the rack 304. The limiting plate 312 prevents the sliding rod 310 from disengaging, and the spring 313 prevents loosening during the sliding process.

[0030] Specifically, such as Figure 2 and Figure 5 As shown, a device housing 4 is embedded in one side of the outer wall of the drive housing 2, and a photovoltaic module 5 is embedded in the top of the device housing 4. A connecting sleeve 6 is fixedly installed at one end of the worm gear 306, and a positioning mechanism 7 is provided at the other end of the connecting sleeve 6. The positioning mechanism 7 includes a threaded rod 701, which protrudes from the inner wall of the connecting sleeve 6. A sliding plate 702 is slidably connected to the outer wall of the end of the threaded rod 701 that protrudes into the connecting sleeve 6. A limiting groove 704 is opened inside the sliding plate 702. An abutment block 703 is fixedly installed on one side of the limiting groove 704 at the front end of the sliding plate 702. A slider 705 is fixedly installed at one end of the sliding plate 702. A sliding groove 706 is opened inside the drive housing 2 at the position corresponding to the slider 705.

[0031] By adopting the above technical solution, the rechargeable battery, inverter and other components installed inside the equipment housing 4 are used to cooperate with the photovoltaic module 5 to utilize resources. After being connected by a line, they transmit electrical energy to the electromagnet 302. When the worm 306 rotates, it drives the connecting sleeve 6 to push the threaded rod 701 to move the sliding plate 702, so that the contact block 703 can abut against both sides of the worm wheel 307 and press it tightly, further improving the stability of the valve stem 308 and preventing loosening. At the same time, the position of the worm wheel 307 is reserved in conjunction with the limiting groove 704 to avoid the limitation situation during the pressing process. Through the cooperation of the slider 705 and the sliding groove 706, the stability of the sliding plate 702 during the sliding process can be improved.

[0032] Working principle: The valve stem 308, which controls the rotation of the valve plate in the valve body 1, passes through the drive housing 2. By activating the electromagnet 302 embedded in the mounting housing 301, the permanent magnet block 303 with the same magnetic pole is pushed, causing the rack 304 to rise and fall, thereby driving the gear 305 to rotate. The gear 305 drives the worm 306 to rotate, and the worm 306 drives the worm wheel 307 to drive the valve stem 308, causing the valve plate to open and close the valve body 1. The worm 306 meshes with the worm wheel 307, which has a locking effect, thus limiting the movement and preventing loosening. The connecting rod 309 fixed above the worm wheel 307 is rotatably connected to the drive housing 2 via a bearing to improve rotational stability. When the rack 304 moves, it drives the sliding rod 310 to slide through the sleeve 311 to improve stability. At the same time, the limit plate 312 prevents the valve from falling off during reset. When the valve plate needs to be reset, it is reset via a double-pole double-throw switch. The control terminal adjusts the current direction of the electromagnet 302 via an external signal, thereby magnetically attracting the permanent magnet block 303. The spring 313 pushes the limit plate 312 to stably reset the rack 304, thereby driving the valve plate to reset. The equipment housing 4 is equipped with a rechargeable battery, inverter and other adapter components, and is electrically connected to the photovoltaic module 5. It can generate electricity to provide power to the electromagnet 302, and can also charge it. When the worm 306 rotates to close the valve plate, the connecting sleeve 6 drives the threaded rod 701 to rotate, thereby driving the sliding plate 702 to make the contact block 703 abut against the worm wheel 307 to further improve the locking firmness. The position of the worm wheel 307 is reserved by the limit groove 704 to avoid mutual limitation. The sliding plate 702 slides stably along the sliding groove 706 through the slider 705. At the same time, the control terminal and signal receiving terminal of the entire valve body 1 are set inside the equipment housing 4.
