Description

Technical Field

[0001] This utility model relates to the field of vacuum baffle valve technology, specifically a vacuum baffle valve with high sealing performance. Background Technology

[0002] The core function of the vacuum baffle valve is to achieve the sealing and switching of the vacuum environment through the rapid opening and closing of the baffle. When the solenoid directional valve guides compressed air to one side of the actuator cylinder, the air pressure in the cylinder increases, pushing the baffle valve connected to the cylinder to close. When the solenoid directional valve changes the airflow direction and guides the compressed air to the other side of the actuator cylinder, the air pressure in the cylinder decreases, causing the baffle valve to open.

[0003] Chinese Patent Publication No. CN221897206U discloses a pneumatic baffle valve with good sealing performance, including a valve body, an inlet pipe, and an outlet pipe. The inlet pipe is located on the left side of the valve body, and the outlet pipe is located on the right side of the valve body. A first connecting pipe is movably connected to the left side of the inlet pipe, and a second connecting pipe is movably connected to the right side of the outlet pipe. A sealing ring is fixedly connected to the outside of both the inlet and outlet pipes. The sealing ring is movably connected to the first and second connecting pipes, respectively. By connecting the first and second connecting pipes to the valve body, connecting the first limiting rod on the left sealing ring to the first limiting hole, and connecting the second limiting rod on the right sealing ring to the second limiting hole, the sealing performance of the valve body is improved through the thread and the sealing ring. The rotating rod drives the crushing blade to crush weeds and leaves, preventing blockage of the valve body and thus extending the service life of the valve body.

[0004] In the aforementioned prior art, impurities can be crushed by setting the crushing blade to avoid clogging the vacuum baffle valve. However, the crushing blade will gradually wear down with long-term use. The crushing blade used in this device is fixed on the output shaft of the motor, which means that when the crushing blade is worn out, it can only be replaced as a whole, which is not convenient for individual replacement and increases maintenance costs.

[0005] Therefore, it is necessary to propose a vacuum baffle valve with high sealing performance to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum baffle valve with high sealing performance, so as to solve the problem mentioned in the background art that the internal crushing blade of the baffle valve is fixed on the output shaft of the motor, which means that when the crushing blade is worn and damaged, it can only be replaced as a whole, and it is not convenient to replace it individually.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vacuum baffle valve with high sealing performance, comprising a vacuum baffle valve, a connecting pipe installed on the vacuum baffle valve, a movable ring rotatably installed inside the connecting pipe, a crushing structure connected to the movable ring, a positioning structure and a fixing screw connected to the crushing structure, and a reinforcing structure connected to the fixing screw.

[0008] Preferably, the crushing structure includes several connecting strips, which are detachably installed on the inner wall of the movable ring. Several T-shaped plates are movably installed inside the connecting strips, and crushing blades are installed on one side of the T-shaped plates.

[0009] Preferably, a gear ring is fixedly sleeved on the movable ring, a gear is rotatably installed inside the connecting pipe, the gear meshes with the gear ring, a motor is installed on the connecting pipe, and the output end of the motor is installed on the gear.

[0010] Preferably, a bearing is installed on the inner wall of the connecting pipe, and the inner ring of the bearing is fitted onto the movable ring.

[0011] Preferably, the positioning structure includes a plurality of T-shaped slots, which are formed on the connecting strip, and the T-shaped plates are movably installed in the corresponding T-shaped slots.

[0012] Preferably, the inner wall of the movable ring is equipped with several limiting baffles, and the T-shaped plate is in contact with the corresponding limiting baffle.

[0013] Preferably, the reinforcing structure includes several screw holes, which are opened inside the movable ring. One end of the fixing screw passes through the connecting strip and is threaded into the screw hole. Several T-shaped positioning grooves are opened inside the movable ring. T-shaped strips are slidably installed in the T-shaped positioning grooves and are installed on one side of the connecting strip.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) In this utility model, after the connecting pipe is removed from the connected pipe, the connecting strip can be pulled out from the movable ring by rotating and unscrewing the fixing screw. At this time, the T-plate will be separated from one side of the limit baffle. The crushing blade can be removed by pushing the T-plate, which makes it convenient to replace the worn or damaged crushing blade without replacing the whole thing, thus reducing maintenance costs.

[0016] (2) By turning on the motor, the gear can be driven to rotate. The gear will drive the moving ring to rotate through meshing with the gear ring, which in turn drives the internal crushing blade to rotate in a circular motion. The rotating crushing blade can crush the debris in the water and prevent it from clogging the vacuum baffle valve and affecting its sealing performance. Attached Figure Description

[0025] 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.

[0026] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a vacuum baffle valve with high sealing performance, including a vacuum baffle valve 100, a connecting pipe 200 installed on the vacuum baffle valve 100, a movable ring 201 rotatably installed inside the connecting pipe 200, a crushing structure connected to the movable ring 201, the crushing structure can be used to crush impurities, a positioning structure and a fixing screw 400 are connected to the crushing structure, and a reinforcing structure is connected to the fixing screw 400. The positioning structure and the reinforcing structure can be used to position and fix the components of the crushing structure, which is convenient for disassembly and assembly.

[0027] Furthermore, the crushing structure includes several connecting bars 202, which are detachably installed on the inner wall of the movable ring 201. Several T-shaped plates 203 are movably installed inside the connecting bars 202, and crushing blades 204 are installed on one side of the T-shaped plates 203. When the movable ring 201 rotates, it can drive the connecting bars 202, T-shaped plates 203 and crushing blades 204 to move in a circular motion, so that the crushing blades 204 can crush the debris.

[0028] Furthermore, a gear ring 205 is fixedly sleeved on the movable ring 201, and a gear 206 is rotatably installed inside the connecting pipe 200. The gear 206 meshes with the gear ring 205. A motor 207 is installed on the connecting pipe 200, and the output end of the motor 207 is installed on the gear 206. When the motor 207 is turned on, it can drive the gear 206 to rotate. The gear 206 can drive the movable ring 201 to rotate by meshing with the gear ring 205.

[0029] Furthermore, a bearing 208 is installed on the inner wall of the connecting pipe 200. The inner ring of the bearing 208 is fitted onto the movable ring 201. When the movable ring 201 rotates, it can drive the inner ring of the bearing 208 to rotate. The bearing 208 makes the rotation of the movable ring 201 smoother.

[0030] Example 2: Figure 3-5 To facilitate the replacement of worn crushing blades 204, a positioning structure and a reinforcement structure are provided. The positioning structure includes several T-shaped slots 300, which are formed on the connecting strip 202. T-shaped plates 203 are movably installed in the corresponding T-shaped slots 300. Several limiting baffles 301 are installed on the inner wall of the movable ring 201, and the T-shaped plates 203 contact the corresponding limiting baffles 301. The reinforcement structure includes several screw holes 401, which are formed inside the movable ring 201. One end of the fixing screw 400 passes through the connecting strip 202 and is threaded into the screw hole 401. The device has several T-shaped positioning grooves 402 inside, and a T-shaped strip 403 is slidably installed in the T-shaped positioning groove 402. The T-shaped strip 403 is installed on one side of the connecting strip 202. Rotating the fixing screw 400 and unscrewing it from the screw hole 401 can release the connection restriction on the connecting strip 202. Then, pulling the connecting strip 202 can drive the T-shaped plate 203 and the crushing blade 204 to disengage from the movable ring 201. At the same time, the T-shaped plate 203 will be released from the obstruction of the limiting baffle 301. At this time, pushing the T-shaped plate 203 can make it disengage from the T-shaped slot 300 so that the crushing blade 204 can be disassembled. The remaining features are the same as in Embodiment 1.

[0031] The working principle is as follows: Turning on the motor 207 drives the gear 206 to rotate. The gear 206, through meshing with the gear ring 205, drives the movable ring 201 to rotate. The movable ring 201 drives the connecting bar 202, the T-shaped plate 203, and the crushing blade 204 to rotate in a circular motion, enabling the crushing blade 204 to crush debris. When the worn crushing blade 204 needs to be replaced, the pipe connected by the connecting pipe 200 can be removed to expose the fixing screw 400. By rotating the fixing screw 400 and unscrewing it from the screw hole 401, the connection restriction on the connecting bar 202 can be released. Then, pulling the connecting bar 202 can pull the T-shaped bar 403 out of the T-shaped positioning groove 402, and drive the T-shaped plate 203 and the crushing blade 204 to rotate. The T-plate 203 disengages from the movable ring 201, causing one side of the T-plate 203 to disengage from the limiting baffle 301. Pushing the T-plate 203 allows it to disengage from the T-slot 300, enabling the removal of the crushing blade 204. During installation, the T-plate 203 is slid into the T-slot 300 for initial positioning. The T-strip 403 on the connecting strip 202 is then inserted into the T-positioning groove 402. The fixing screw 400 is then passed through the connecting strip 202 and re-screwed into the screw hole 401 for fixation, preventing the connecting strip 202 from detaching from the movable ring 201. During installation, the connecting strip 202 causes the T-plate 203 to contact one side of the limiting baffle 301, preventing the T-plate 203 from detaching from the crushing blade 204, thus completing the installation operation.

[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
