Description

Technical Field

[0001] The present invention relates to the technical field of valves, in particular to an adjustable hidden valve. Background Art

[0002] Valves are control components in fluid conveying systems, used to open and close pipelines, control flow direction, and perform other functions. They are mainly divided into manual valves and electric valves. Manual valves are widely used in industrial production due to their simple installation and easy operation, and are often used on production equipment.

[0003] Because the main operating component of the valve is the valve handle, the valve handle is often of a certain length and protrudes from the valve for the sake of labor saving. In an industrial production environment with a large flow of people and logistics, there is a risk of people or objects accidentally touching the valve, which in turn causes abnormal opening and closing of the pipeline or abnormal flow. Therefore, there is a hidden valve that can hide the valve handle when the valve is in stable use, avoiding the risk of accidental touching and protecting the valve handle.

[0004] In the actual production process, production equipment often cannot maintain long-term stability. In emergency situations such as production equipment failure, it is often necessary to urgently open and close the pipelines that are deeply involved in the production process. However, the existing concealed valves require a certain amount of time to reset the valve handle, and require certain professional knowledge of the concealed valve. It is difficult for those who do not understand the valve concealment principle to know how to reset the valve handle. Therefore, in an emergency, the existing concealed valves will not be able to open and close the valves to control the pipelines according to the situation, which will lead to adverse effects on equipment and products.

[0005] For this reason, an adjustable hidden valve is proposed. Summary of the Invention

[0016] 4. The mechanism in which the rotating plate is tilted by force will not drive the emergency opening and closing adjustment when a single adjustment button is pressed, thereby further preventing accidental touch and further ensuring the stable use of the valve body.

[0017] 5. When the driving rack is extended to start the opening and closing adjustment function, the driving rack contacts the inclined surface of the lever and pushes the piston up. The piston injects the internal medium into the liquid injection cylinder through the liquid pipe. The medium further pushes the push shaft up, allowing the push plate to push the valve handle out of the hidden cylinder. Then, while starting the opening and closing adjustment function, the valve handle is moved out for quick access, making it easier to connect the valve handle and the valve stem for subsequent opening and closing operations, thereby improving operating efficiency.

[0033] Example 1: Figure 1-10As shown, an adjustable hidden valve includes a valve body 10. The valve body 10 adopts a manual ball valve. A valve stem 11 is rotatably mounted on the center of the top surface of the valve body 10. A valve handle 12 is fixedly mounted on the valve stem 11. The valve body 10, the valve stem 11 and the valve handle 12 are all existing well-known technologies and are not described in detail here. A limit rod 13 is fixedly mounted on the top surface of the valve body 10. The connecting end of the valve handle 12 is provided with a protrusion for contacting the limit rod 13 to limit the rotation angle. It is characterized in that both side surfaces of the valve body 10 are connected to an extension platform 14, and an opening and closing adjustment component for independently driving the rotation of the valve stem is provided on the extension platform 14. It should be noted that the opening and closing adjustment There are two groups of joint components, which are used to drive the valve stem 11 to open and close respectively. The two groups of opening and closing adjustment components are arranged opposite to the valve stem 11. The extension platform 14 is also provided with an energy storage drive component that can store energy to provide power for the opening and closing adjustment component. A hidden component for accommodating the valve handle 12 is provided on one side of the valve body 10. It should be noted that the specific orientation of the structural features provided in this application is not limited in size and can be adjusted. The opening and closing adjustment component includes an adjusting gear 15, which is provided on the valve stem 11 and can rotate with the valve stem 11. A rack cylinder 16 is connected to the extension platform 14, and the rack cylinder 16 is on the left. The side opening is slidably connected with a driving rack 17, the position of the driving rack 17 corresponds to the adjusting gear 15, the end of the driving rack 17 is plugged with a plug rod, and the free end of the plug rod is connected to the rack cylinder 16, the power action end of the energy storage drive assembly is arranged on the driving rack 17, the bottom of the driving rack 17 is fixedly connected with a follow-up rack 18, and ratchet teeth are provided on both sides of the follow-up rack 18. The ratchet teeth are inclined teeth, and the inner walls on both sides of the rack cylinder 16 are slidably connected with lifting rods 21, and the corresponding surfaces of the two lifting rods 21 are connected to guide rods 20, and a limiting rack 19 is provided on the guide rod 20. The limiting rack 19 can be adjusted on the guide The rod 20 slides left and right, and a support spring 22 is connected between the limit rack 19 and the lifting rod 21 for pushing the limit rack 19 to reset after sliding. The corresponding surfaces of the two limit racks 19 are provided with ratchet teeth, and the ratchet teeth on the limit rack 19 and the ratchet teeth on the follow-up rack 18 are staggered, and the limit rack 19 is engaged with the follow-up rack 18 at the corresponding position. A C-shaped connecting plate 23 is provided on both sides of the rack cylinder 16, and through holes are provided on both sides of the rack cylinder 16 at the positions corresponding to the connecting plates 23. The connecting plate 23 and the lifting rod 21 are fixedly connected by screws, and the top surface of the connecting plate 23 is connected with an adjustment button 24.

[0034] Specifically, first operate the energy storage drive component to store energy. When the valve body 10 stops operating, the valve handle 12 is accommodated inside by the hidden component, thereby avoiding the occurrence of accidental touch and providing waterproof and anti-corrosion protection for the valve handle 12, and the drive rack 17 is kept in the position stored in the rack cylinder 16 by the engagement of the follow-up rack 18 and the limit rack 19. When an emergency occurs, by pressing the adjustment button 24, the adjustment button 24 pushes the limit rack 19 down through the lifting rod 21 and the guide rod 20, so that the follow-up rack 18 is disengaged from the limit rack 19, and the energy storage drive component releases power and applies power to the drive rack 17, pushing the drive rack 17 to slide out of the rack cylinder 16, and the drive rack 17 engages with the adjusting gear 15 by sliding, thereby driving the adjusting gear 15 to rotate, and the adjusting gear 15 drives the valve stem 11 to rotate, thereby realizing emergency opening and closing adjustment of the valve body 10 in the absence of the valve handle 12.

[0035] like Figure 5 As shown, a repelling magnet 25 is installed on the top surface of the rack cylinder 16, and a magnet (not shown in the figure) with the same magnetic pole as the corresponding surface of the repelling magnet 25 is connected to the bottom surface of the adjustment button 24.

[0036] Specifically, through the repulsive force between the repulsive magnet 25 and the magnet on the adjustment button 24, resistance is provided for the descent of the adjustment button 24. When the adjustment button 24 is accidentally touched, it is difficult to descend, resulting in the operation of the energy storage drive component, and a reset lift is provided after the adjustment button 24 descends. The size of the magnetic force of the repulsive magnet 25 can be set according to needs.

[0037] like Figure 5 and Figure 7 As shown, the inner walls on both sides of the rack cylinder 16 are provided with a sliding groove 26 with a T-shaped cross section, and the opposing surfaces of the two lifting rods 21 are connected to a slider 27, which is sleeved in the sliding groove 26.

[0038] Specifically, the sliding groove 26 and the sliding block 27 guide the lifting of the lifting rod 21, so that the lifting action of the lifting rod 21 is more accurate and smooth.

[0039] like Figure 1 As shown, the extension 14 is shown with a labeling strip 28 connected thereto, which serves to indicate the function of the adjustment button 24 at that location.

[0040] Specifically, the function of the regulating button 24 is identified by the label strip 28 so that an operator who has relevant knowledge of the device can complete the operation purpose of emergency opening and closing the regulating valve stem 11 with simple prompts.

[0041] like Figure 2 and Figure 3As shown, a slot 29 is provided on the surface of the valve stem 11, a screw is connected to the surface of the adjusting gear 15 and the screw is sleeved in the slot 29, a fixing ring 30 is fixedly connected to the surface of the valve stem 11 above the adjusting gear 15, a return spring 31 is connected between the fixing ring 30 and the adjusting gear 15, a sliding margin is left between the bottom surface of the adjusting gear 15 and the valve body 10, a positioning shaft 32 is connected to the top surface of one side of the adjusting gear 15, a circular hole adapted for the positioning shaft 32 is provided on the top surface of the valve handle 12 and is sleeved with the positioning shaft 32, and a circle of annular protrusions is provided on the surface of the positioning shaft 32 for contacting the bottom surface of the valve handle 12.

[0042] Specifically, when the adjusting gear 15 rotates, the screw pushes the slot 29 to drive the valve stem 11 to rotate, and the positioning shaft 32 rotates with the adjusting gear 15. When the valve handle 12 is connected to the valve stem 11, the round hole needs to be inserted into the positioning shaft 32, so that when the valve handle 12 is connected, the valve handle 12 can be guided to the position corresponding to the direction after the valve stem 11 is rotated, ensuring that the valve ball in the valve body 10 will not have position deviation when the valve handle 12 is used subsequently. After the valve handle 12 is installed, downward pressure is applied to the positioning shaft 32, and the screw on the adjusting gear 15 descends along the slot 29, allowing the adjusting gear 15 to remain connected to the valve stem 11 and change the upper and lower positions of the adjusting gear 15, so that the position of the adjusting gear 15 is staggered with the drive rack 17, thereby facilitating the storage of the drive rack 17 for reuse.

[0043] like Figure 5 As shown, the top surface of the connecting plate 23 is open, and a fixed shaft 41 is connected to the center of the top surface of the connecting plate 23 . The surface of the fixed shaft 41 is rotatably connected to a rotating plate 42 . There are two adjustment buttons 24 connected to both sides of the rotating plate 42 .

[0044] Specifically, when the adjustment button 24 is pressed alone, the rotating plate 42 will be tilted by force, and the cover plate of the mask will limit the downward position of the finger, so that the connecting plate 23 will not be forced to descend. When the two adjustment buttons 24 are pressed at the same time, the rotating plate 42 remains balanced and will not rotate, so that the force can be applied to the connecting plate 23 through the fixed shaft 41, thereby driving the connecting plate 23 to descend. Using this mechanism, when only one adjustment button 24 is pressed, the emergency opening and closing adjustment will not be driven, thereby achieving further prevention of accidental touch.

[0045] like Figure 5 and Figure 6As shown, the energy storage drive assembly includes an energy storage cylinder 33, a groove is provided on the top surface of the extension platform 14, and the energy storage cylinder 33 is connected in the groove, an energy storage spring 34 is connected to the inner wall of the bottom side of the energy storage cylinder 33, a cross shaft 35 is connected to the center of the bottom surface of the energy storage cylinder 33, a cross sleeve 36 is sleeved on the cross shaft 35, the vertical section of the cross sleeve 36 is cross-shaped, the middle part of the cross sleeve 36 is in contact with the energy storage spring 34, the bottom surface of the cross sleeve 36 is provided with a groove adapted to the cross shaft 35 and is inserted into the cross shaft 35, the top surface of the cross sleeve 36 A groove is opened and a rotating rod 38 is sleeved thereon. Several circles of spiral grooves 39 are opened on the surface of the rotating rod 38. The inner wall of the cross sleeve 36 is provided with a spherical protrusion 37 inserted into the spiral groove 39. The top surface of the rotating rod 38 is connected to the toggle gear 40, which is engaged with the drive rack 17. The top surface of the rotating rod 38 is connected to a hexagonal groove. The rotating rod 38 is connected to a frame plate through a rotating bearing. One end of the frame plate is connected to the rack cylinder 16. A cover plate for covering the toggle gear 40 and the connecting plate 23 is provided on the rack cylinder 16.

[0046] Specifically, after the valve handle 12 is installed on the valve stem 11, the adjusting gear 15 is pressed down to a position where it is disengaged from the driving rack 17. At this time, energy can be stored. When storing energy, a hexagonal wrench is connected to the hexagonal groove on the rotating rod 38, and the rotating rod 38 is rotated. When the rotating rod 38 rotates, the spherical protrusion 37 inserted in the spiral groove 39 generates a thrust on the cross sleeve 36, allowing the cross sleeve 36 to slide down on the cross shaft 35 and apply pressure to the energy storage spring 34. When the rotating rod 38 rotates, it drives the toggle gear 40 to rotate, and the toggle gear 40 pushes the driving rack 17 meshed with it to slide into the rack cylinder 16. When the feed rack 18 slides with the driving rack 17, it contacts the inclined surface of the ratchet gear teeth on the limit rack 19, generating a thrust to slide to both sides for the limit rack 19, and then the limit rack 19 moves along the guide rod 20. The outward movement avoids the sliding of the following rack 18, and then it is reset by the rebound of the support spring 22 after sliding one tooth pitch. After the driving rack 17 is completely received in the rack cylinder 16, the concave surface of the ratchet teeth on the following rack 18 and the limiting rack 19 engages, limiting the sliding of the driving rack 17, thereby preventing the toggle gear 40 from rotating, and the energy storage spring 34 remains in a compressed energy storage state. The elastic force of the energy storage spring 34 can be controlled by changing the model of the energy storage spring 34. After pressing the adjustment button 24, the driving rack 17 loses the limit of the limiting rack 19, and the energy storage spring 34 releases energy by rebounding. The cross sleeve 36 rises as the energy storage spring 34 releases energy, and pushes the cross sleeve 36 to rotate through the spherical protrusion 37, thereby allowing the toggle gear 40 to push the driving rack 17 to extend.

[0047] like Figure 1 and Figure 8As shown, the hidden component includes a hidden tube 43. One side of the valve body 10 is connected to the hidden tube 43. The top surface of the hidden tube 43 is provided with an inner cavity, and the shape of the inner cavity is adapted to the valve handle 12. The top surface of the hidden tube 43 is movably connected to the upper cover 44.

[0048] Specifically, after the valve handle 12 is disassembled, it can be placed in the hidden tube 43 and covered by the upper cover 44, thereby protecting and hiding the valve handle 12.

[0049] like Figure 9 and Figure 10 As shown, a hole is opened on the bottom surface of the hidden tube 43 and a push shaft 46 is sleeved thereon. One end of the push shaft 46 located inside the hidden tube 43 is connected to a push plate 45 .

[0050] Specifically, when taking out the valve handle 12 , the push shaft 46 is pushed upward, so that the push plate 45 pushes the valve handle 12 out of the hidden tube 43 , thereby facilitating the removal of the valve handle 12 .

[0051] Example 2: Figure 11 and Figure 13 As shown, an adjustable hidden valve is provided. A drain cylinder 48 is connected to the corresponding opening on the top surface of the rack cylinder 16. A circular cavity is provided in the drain cylinder 48 and a piston 50 is sleeved therein. A shift rod 51 is connected to the bottom end of the piston 50. The free end of the shift rod 51 is V-shaped and corresponds to the drive rack 17. The bottom surface of the hidden cylinder 43 is connected to the injection cylinder 47. The push shaft 46 is sleeved in the injection cylinder 47. The tops of the drain cylinders 48 of the two sets of opening and closing adjustment components are connected and communicated through liquid pipes 49, and the top of one of the drain cylinders 48 is connected and communicated with the bottom of the injection cylinder 47 through the liquid pipe 49. The drain cylinder 48 is filled with a medium, which can be air or hydraulic oil.

[0052] Specifically, when the drive rack 17 is extended to start the opening and closing adjustment function, the drive rack 17 contacts the inclined surface of the lever 51 and pushes the piston 50 up. The piston 50 injects the internal medium into the liquid injection cylinder 47 through the liquid pipe 49. The medium further pushes the push shaft 46 to rise, allowing the push plate 45 to push the valve handle 12 out of the hidden cylinder 43. Then, while starting the opening and closing adjustment function, the valve handle 12 is moved out for quick access, making it easy to operate the valve handle 12 to connect with the valve stem 11 for subsequent opening and closing operations.

[0053] Working principle:

[0054] Before use: Connect the valve body 10, valve stem 11 and valve handle 12 and install them in the piping system. Use a hexagonal wrench to insert into the hexagonal slot on the rotating rod 38 to drive the driving rack 17 in the direction of storage in the rack cylinder 16 to drive the toggle gear to rotate until the driving rack 17 is stored in the rack cylinder 16.

[0055] When in use: First, rotate the valve handle 12 to control the flow of the pipeline system until the production equipment can operate stably, then remove the valve handle 12 from the valve stem 11 and store it in the hidden component, and the adjustment gear 15 is pulled by the return spring 31 to rise to the position corresponding to the drive rack.

[0056] In the second step, when a situation arises where the valve body 10 needs to be urgently adjusted, the two adjustment buttons 24 on one side are pressed simultaneously according to the situation. The energy storage drive assembly drives the drive rack 17 to extend, and the drive rack 17 drives the valve stem 11 to rotate through the adjustment gear 15 to realize emergency adjustment of the valve body 10.

[0057] The third step is to instruct non-professionals to operate the opening and closing adjustment component by instructing them to check the information on the label strip 28 for guidance.

[0058] In the fourth step, after the opening and closing adjustment component is operated, the push plate 45 pushes the valve handle 12 out of the hidden tube 43. After the operator takes it out, it is aligned with the positioning shaft 32 and installed on the valve stem 11 for subsequent adjustment.

[0059] After use: the regulating gear 15 is pressed down by the valve handle 12 and is disengaged from the corresponding drive rack, and a hexagonal wrench is inserted into the hexagonal slot on the rotating rod 38 to repeat the energy storage.

[0060] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
