Description

Technical Field

[0001] This invention relates to the field of safety valve technology, and in particular to a safety valve with an anti-accidental touch warning function. Background Technology

[0002] Solenoid valves and directional valves are basic automated control components that control fluids by controlling compressed air. They are generally used in industrial control systems, not limited to hydraulic or pneumatic systems. In industrial control systems, solenoid valves can be used with different electronic control circuits to achieve control effects by adjusting the direction, flow rate, and other control parameters of the medium. At the same time, the control precision, accuracy, and flexibility can be guaranteed. There are many types of solenoid valves and directional valves, each playing a role in different positions in the control system. Among them, the more commonly used ones are check valves, safety valves, and manual directional valves.

[0003] Existing manual directional valves are all exposed to the external environment, inevitably subject to collisions with external objects during operation. Furthermore, the operating environment is relatively hot, making them susceptible to damage from steam leaks and other issues. This can shorten the valve's lifespan, affect its normal operation, and in severe cases, cause the valve handle to reverse, forcing the controlled actuator to operate and resulting in equipment accidents. Therefore, developing a safety valve with anti-accidental touch warning functionality is of great significance. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a safety valve with an anti-accidental touch warning function, thus solving the problems mentioned in the background section.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A safety valve with an anti-accidental touch warning function includes a left protective shell, a right protective shell, and an adjusting handle rotatably mounted on the valve body, and further includes: The disassembly and assembly section is used to disassemble and assemble the left protective shell and the right protective shell. The disassembly and assembly section consists of two plug-in components, each of which includes a connecting plate fixedly installed on the left protective shell. A through hole is provided on the right protective shell, and the through hole corresponds to the position of the adjustment handle; The locking part is used to lock the position of the adjustment handle on the right protective shell. The locking part includes two movable grooves symmetrically opened on the side wall of the through hole, and a locking block that cooperates with the adjustment handle is slidably installed in each of the two movable grooves. Two adjustment mechanisms that cooperate with the corresponding locking blocks are installed on the right protective shell. The warning unit is used to issue an alarm when the adjustment handle is turned accidentally. The warning unit includes a warning light fixedly installed on the right protective shell. Both locking blocks are equipped with a trigger mechanism, and one of the trigger mechanisms cooperates with the warning light. The reinforcement part is used to reinforce the adjustment handle when it is accidentally rotated. The reinforcement part includes two symmetrically slidingly mounted reinforcement blocks at the front end of the right protective shell, and the two reinforcement blocks are respectively engaged with two actuation mechanisms.

[0006] Furthermore, the connecting plate has a plug-in slot, the right protective shell has a storage slot, and a plug-in plate that mates with the plug-in slot is slidably installed in the storage slot. A rotating rod is rotatably installed on the right protective shell, and two top blocks that mate with the plug-in plate are fixedly installed on the side wall of the rotating rod located in the storage slot. A knob is fixedly installed on the end of the rotating rod located outside the right protective shell, and a torsion spring is installed between the knob and the right protective shell. Two limiting blocks are fixedly installed on the side wall of the plug-in plate, and two limiting slots that mate with the corresponding limiting blocks are opened on the side wall of the storage slot.

[0007] Furthermore, the adjusting mechanism consists of a moving block, a lead screw, an incomplete gear, a connecting groove, and a fixed rack. The moving block is fixedly installed on the side wall of the locking block away from the midpoint of the through hole. The connecting groove is opened on the side wall of the moving groove. The lead screw is rotatably installed in the connecting groove and is threadedly connected to the moving block. The incomplete gear is fixedly installed on the end of the lead screw away from the moving block. The fixed rack is vertically slidably installed in the connecting groove and meshes with the incomplete gear.

[0008] Furthermore, a screw is rotatably mounted on the top of the right protective shell, and a fixing rod is threaded onto the screw. The bottom of the fixing rod is fixedly connected to the top of the two fixing racks.

[0009] Furthermore, the actuation mechanism comprises a sliding groove, an arc-shaped block, a contact block, an arc-shaped rack, a rotating shaft, a turntable, a fixed gear, and a second torsion spring. The sliding groove is formed on the locking block, the arc-shaped block is slidably installed in the sliding groove, the contact block is fixedly installed at one end of the arc-shaped block near the midpoint of the through hole, the arc-shaped rack is fixedly installed at one end of the arc-shaped block outside the sliding groove, the rotating shaft is rotatably installed at the front end of the right protective shell, the turntable is fixedly installed on the rotating shaft, the fixed gear is fixedly installed at one end of the rotating shaft away from the turntable, and the fixed gear meshes with the arc-shaped rack. The second torsion spring is installed between the turntable and the right protective shell.

[0010] Furthermore, an energized plate is fixedly installed on the right protective shell, and a conductive ring is fixedly installed on the turntable. The conductive ring, the energized plate, and the warning light are all electrically connected. A conductive plate is fixedly installed on the side wall of the conductive ring, and the conductive plate and the energized plate are positioned correspondingly.

[0011] Furthermore, two sliding grooves are provided on the right protective shell, and sliders are slidably installed in each of the sliding grooves. Compression springs are installed between the two sliders and the corresponding sliding grooves. Two connecting blocks that slide and cooperate with the corresponding sliders are fixedly installed on the reinforcing block. Guide posts that slide and cooperate with the sliders are fixedly installed in the sliding grooves.

[0012] Furthermore, a jacking block is fixedly installed on one side wall of the turntable near the reinforcing block, and a protrusion corresponding to the position of the jacking block is fixedly installed on the side wall of the reinforcing block. The jacking block has a groove that matches the protrusion, and the depth of the groove is less than the length of the connecting block.

[0013] Furthermore, two magnetic posts are fixedly installed on the side wall of the reinforcing block, and two positioning holes that cooperate with the corresponding magnetic posts are opened on the side wall of the right protective shell, and the depth of the positioning holes is less than the depth of the groove.

[0014] Compared with existing technologies, the advantages of this invention are: 1. By cooperating with the two locking blocks and the regulating mechanism, the regulating handle can be locked after the flow direction and flow rate of the medium in the valve body are controlled, reducing the possibility of accidental rotation and improving the working stability of the valve body.

[0015] 2: By coordinating the warning light with the trigger mechanism, if the adjustment handle is accidentally turned, the movement of the contact block on the locking block will automatically trigger the warning light to sound an alarm, alerting the staff to the accidental touch and allowing them to readjust in time, thus preventing the equipment malfunction from escalating further.

[0016] 3: Through the cooperation of the push block, the protrusion and the reinforcement, when the adjustment handle is accidentally touched and the contact block is moved, the two reinforcement blocks can clamp and lock the adjustment handle again at the same time as the warning light sounds an alarm, reducing the rotation amplitude when it is accidentally touched, thereby reducing the impact of accidental touch on the valve body operation.

[0017] 4. The combination of the left and right protective shells prevents the valve body adjustment handle from being exposed to the outside for a long time, thus preventing corrosion caused by wind, sun and rain, and effectively improving the service life of the valve body.

[0018] In summary, this invention can lock the regulating handle after controlling the flow direction and flow rate of the medium in the valve body. When the regulating handle is accidentally touched and deflected, its movement automatically triggers the warning light and allows the two reinforcing blocks to clamp and lock the regulating handle again. This can prompt the staff to make timely adjustments to prevent further damage to the equipment and also reduce the rotation amplitude of the regulating handle when it is accidentally touched, thereby reducing the impact of accidental touch on the operation of the valve body.

[0021] Reference Figures 1-15 A safety valve with an anti-accidental touch warning function includes a left protective shell 3, a right protective shell 4, and an adjusting handle 2 rotatably mounted on the valve body 1. It also includes a disassembly and assembly part, which is used to disassemble and assemble the left protective shell 3 and the right protective shell 4. The disassembly and assembly part consists of two plug-in components.

[0022] The following describes one of the plug-in components in detail. The plug-in component includes a connecting plate 6 fixedly installed on the left protective shell 3, with a plug-in groove 8 on the connecting plate 6. A storage groove 9 is provided on the right protective shell 4, and a plug-in plate 7 that mates with the plug-in groove 8 is slidably installed in the storage groove 9. A rotating rod 11 is rotatably installed on the right protective shell 4, and two top blocks 12 that mate with the plug-in plate 7 are fixedly installed on the side wall of the rotating rod 11 located inside the storage groove 9. A knob 13 is fixedly installed on the end of the rotating rod 11 located outside the right protective shell 4, and a torsion spring 14 is installed between the knob 13 and the right protective shell 4. Two limiting blocks 10 are fixedly installed on the side wall of the plug-in plate 7, and two limiting grooves that mate with the corresponding limiting blocks 10 are provided on the side wall of the storage groove 9. Under the cooperation of the limiting blocks 10 and the limiting grooves... The position of the plug-in plate 7 in the storage slot 9 can be defined. When the left protective shell 3 and the right protective shell 4 are connected, the rotating rod 11 can be rotated under the elastic force of the torsion spring 14. The design of the top block 12 on the rod pushes the plug-in plate 7 out of the storage slot 9 and inserts it into the plug-in slot 8. At this time, the stable connection between the left protective shell 3 and the right protective shell 4 can be guaranteed. At the same time, when it is necessary to separate the left protective shell 3 and the right protective shell 4, the knob 13 is turned to separate the top block 12 from the plug-in plate 7, and the plug-in plate 7 can be disconnected from the plug-in slot 8. At this time, the left protective shell 3 and the right protective shell 4 can be separated directly. The disassembly and assembly operation is simple. The connecting plate 6 of the other plug-in component is fixed on the right protective shell 4, and the corresponding plug-in plate 7 is located on the left protective shell 3. It will not be described in detail here.

[0023] Through hole 5 is located on the right protective shell 4 and corresponds to the position of the adjusting handle 2. Through hole 5 allows the adjusting handle 2 to pass between the left protective shell 3 and the right protective shell 4. The adjusting handle 2 consists of a rotating post and a connecting rod. Figure 1 As shown, the rotating column corresponds to the through hole 5, and the plug rod is inserted and fixed on the rotating column. Rotating the plug rod can control the flow direction and flow rate of the medium. The plug rod also makes it easier to disassemble and assemble the left protective shell 3 and the right protective shell 4.

[0024] The locking part is used to lock the position of the adjusting handle 2 on the right protective shell 4. The locking part includes two moving grooves 15 symmetrically opened on the side wall of the through hole 5, and a locking block 16 that cooperates with the adjusting handle 2 is slidably installed in each of the two moving grooves 15. After the valve body 1 is adjusted, the two locking blocks 16 are tightly attached to the left and right side walls of the adjusting handle 2 respectively, so that the position of the adjusting handle 2 can be limited, thereby locking the adjustment effect of the valve body 1. Two adjusting mechanisms that cooperate with the corresponding locking blocks 16 are installed on the right protective shell 4. The adjusting mechanism consists of a moving block 17, a lead screw 18, an incomplete gear 19, a connecting groove 20 and a fixed rack 21. The movable block 17 is fixedly installed on the side wall of the locking block 16 away from the midpoint of the through hole 5. The connecting groove 20 is opened on the side wall of the movable groove 15. The lead screw 18 is rotatably installed in the connecting groove 20 and is threadedly connected to the movable block 17. The incomplete gear 19 is fixedly installed on the end of the lead screw 18 away from the movable block 17. The fixed rack 21 is vertically slidably installed in the connecting groove 20 and meshes with the incomplete gear 19. When the fixed rack 21 moves down in the connecting groove 20, its meshing with the incomplete gear 19 causes the lead screw 18 to rotate, thereby causing the movable block 17 to push the locking block 16. The moving groove 15 moves towards the through hole 5, and then the two locking blocks 16 move closer to each other to lock the adjusting handle 2. A screw 23 is rotatably installed on the top of the right protective shell 4, and a fixing rod 22 is threaded on the screw 23. The bottom of the fixing rod 22 is fixedly connected to the top of the two fixing racks 21. Through the cooperation of the screw 23 and the fixing rod 22, it is easy to control the movement of the two fixing racks 21 at the same time, so that the movement of the two locking blocks 16 can be controlled at the same time. Moreover, the threaded connection between the screw 23 and the fixing rod 22 can improve the stability of the fixed rack 21 after the position is adjusted compared with other connection methods.

[0025] The warning unit is used to issue an alarm when the adjustment handle 2 is accidentally turned. The warning unit includes a warning light 33 fixedly installed on the right protective shell 4. Both locking blocks 16 are equipped with a trigger mechanism, and one of the trigger mechanisms cooperates with the warning light 33. The trigger mechanism consists of a sliding groove 24, an arc block 25, a contact block 26, an arc rack 27, a rotating shaft, a turntable 28, a fixed gear, and a torsion spring 29. A sliding groove 24 is formed on the locking block 16. An arc-shaped block 25 is slidably installed in the sliding groove 24. A contact block 26 is fixedly installed at one end of the arc-shaped block 25 near the midpoint of the through hole 5. An arc-shaped rack 27 is fixedly installed at one end of the arc-shaped block 25 outside the sliding groove 24. A rotating shaft is rotatably installed at the front end of the right protective shell 4. A turntable 28 is fixedly installed on the rotating shaft. A fixed gear is fixedly installed at the end of the rotating shaft away from the turntable 28, and the fixed gear meshes with the arc-shaped rack 27. A second torsion spring 29 is installed between the turntable 28 and the right protective shell 4. The elastic force of the second torsion spring 29 can ensure that the turntable 28 remains stationary relative to the right protective shell 4 when no external force is applied, while the turntable 28 remains stationary relative to the right protective shell 4 when passing through two... After the locking block 16 locks the adjusting handle 2, if the adjusting handle 2 is accidentally touched and rotates, the contact block 26 located on the two locking blocks 16 can move with the rotation of the adjusting handle 2 due to the contact effect with the adjusting handle 2 and the sliding effect between the locking block 16. At this time, the cooperation between the arc rack 27 and the fixed gear causes the turntable 28 to rotate against the elastic force of the torsion spring 29. The side wall of the moving groove 15 is provided with an arc groove that cooperates with the arc block 25. When the locking block 16 is in contact with the adjusting handle 2, the arc block 25 corresponds to the position of the arc groove. At this time, the arc block 25 can slide smoothly on the locking block 16. A conductive plate 32 is fixedly installed on the right protective shell 4, and a conductive ring 30 is fixedly installed on the turntable 28. The conductive ring 30, the conductive plate 32, and the warning light 33 are all electrically connected. A conductive piece 31 is fixedly installed on the side wall of the conductive ring 30, and the conductive piece 31 corresponds to the conductive plate 32. When the turntable 28 rotates, whether clockwise or counterclockwise, one of the conductive pieces 31 on the conductive ring 30 will contact the conductive piece 32. At this time, the warning light 33 can emit a warning signal to alert the user. The indicator shows that the adjustment handle 2 has been accidentally touched, allowing the operator to control the valve body 1 in a timely manner. The electrical connection of the energized plate 32, conductive plate 31, conductive ring 30, and warning light 33 is achieved through a battery and wires. The energized plate 32 is connected to the positive terminal of the battery through a wire, the conductive ring 30 is connected to the negative terminal of the battery through a wire, and the warning light 33 is connected in the closed loop of the entire circuit. When one of the conductive plates 31 contacts the energized plate 32, the positive and negative terminals of the battery are connected, and the warning light 33 can emit a signal at this time.

[0026] The reinforcement section is used to reinforce the adjusting handle 2 in case of accidental rotation. The reinforcement section includes two symmetrically slidably mounted reinforcing blocks 34 at the front end of the right protective shell 4. The right protective shell 4 has two grooves, each containing a slider 35. A compression spring 36 is installed between each slider 35 and its corresponding groove. Two connecting blocks 37 are fixedly mounted on the reinforcing blocks 34, slidingly engaging with the corresponding sliders 35. Guide posts that slide with the sliders 35 are fixedly mounted in the grooves. Under the elastic force of the compression springs 36, when the reinforcing blocks 34 move unimpeded, the sliders 35 can move the reinforcing blocks 34 closer to the center of the through hole 5. The clamping effect of the two reinforcing blocks 34 reinforces the adjusting handle 2, preventing accidental large-scale rotation. A [missing information - likely a typo, should be "fixed on the side wall of the reinforcing block 34"]. Two magnetic pillars 38 are provided. Two positioning holes are provided on the side wall of the right protective shell 4 to cooperate with the corresponding magnetic pillars 38. When the magnetic pillars 38 are located in the positioning holes, the position of the reinforcing block 34 relative to the right protective shell 4 can be limited. Therefore, the position of the reinforcing block 34 on the right protective shell 4 can be kept unchanged when the adjustment handle 2 is not accidentally touched. The sliding cooperation between the connecting block 37 and the slider 35 can ensure that when the reinforcing block 34 needs to reinforce the adjustment handle 2, the reinforcing block 34 can have enough space to move relative to the right protective shell 4 to separate the magnetic pillars 38 from the positioning holes. The magnetic pillars 38 are magnetic pillars. In order to improve the stability of the reinforcing block 34 when the adjustment handle 2 is not accidentally touched, an iron plate can be fixed in the positioning hole. The magnetic adsorption effect ensures the stability of the reinforcing block 34 relative to the right protective shell 4 when it is not subjected to external force.

[0027] A push block 40 is fixedly installed on the side wall of the turntable 28 near the reinforcing block 34. A protrusion 39 corresponding to the position of the push block 40 is fixedly installed on the side wall of the reinforcing block 34. The push block 40 has a groove that matches the protrusion 39, and the depth of the groove is less than the length of the connecting block 37. The depth of the positioning hole is less than the depth of the groove. When the turntable 28 rotates due to the movement of the contact block 26, the cooperation between the push block 40 and the protrusion 39 allows the reinforcing block 34 to move away from the right protective shell 4, thereby separating the magnetic post 38 from the positioning hole. At this time, under the elastic force of the compression spring 36, the reinforcing block 34 can move closer to the adjusting handle 2 and fit tightly against it, thus achieving a reinforcing effect.

[0028] The working principle of a safety valve with an anti-accidental touch warning function in this invention is as follows: Assembly: Assemble the left protective shell 3 and the right protective shell 4 as follows Figure 1 As shown, it is installed on the valve body 1, and the operation of the two plug-in components ensures a stable connection between the left protective shell 3 and the right protective shell 4. Adjustment and locking: After the left protective shell 3 and the right protective shell 4 are assembled on the valve body 1, first turn the adjustment handle 2 to adjust the direction and flow of the medium in the valve body 1, then turn the screw 23 to make the fixed rod 22 drive the two fixed racks 21 to move down, so that the two locking blocks 16 clamp and lock the adjustment handle 2. Accidental touch alarm: After locking is completed, if the adjustment handle 2 is accidentally touched and rotated, it will drive the contact block 26 to move. The movement of the contact block 26 will drive the turntable 28 to rotate through the cooperation of the arc rack 27 and the fixed gear. One of the conductive plates 31 on the turntable 28 will contact the energized plate 32, and the warning light 33 will emit an alarm signal to remind the staff that an accidental touch has occurred. Reinforcement after accidental touch: When the turntable 28 rotates, the actuating block 40 on it pushes the protrusion 39, causing the reinforcing block 34 to move and the magnetic post 38 to separate from the positioning hole. At this time, the elastic force of the compression spring 36 causes the reinforcing block 34 to automatically move closer to the adjusting handle 2 and clamp it, thus reinforcing the adjusting handle 2 a second time and reducing its rotation amplitude when accidentally touched.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
