Description

Technical Field

[0001] The present invention relates to the technical field of multi-way valves, and more specifically, to a multi-way valve with hierarchical adjustment. Background Art

[0002] The multi-way valve with hierarchical adjustment is a valve device with an innovative structure. Through hierarchical design and multi-way adjustment functions, precise control of the flow rate, direction, and pressure of fluid media can be achieved.

[0003] After retrieval, a Chinese patent with the publication number CN203627918U, a multi-way valve with hierarchical adjustment, includes a base, a valve body, a valve cover, a valve core, and a runner. The valve body is coaxially and fixedly installed on the base, the valve cover is coaxially installed at the upper end of the valve body, a valve core is installed in the valve body in a guiding and rotating manner, a valve rod is coaxially installed vertically on the valve core. The valve core is composed of upper and lower layers, and semi-open channels that are reversely symmetric are formed at the upper and lower positions corresponding to the valve body on the valve core. A vertical sliding cavity is formed in the middle of the valve core, and a plurality of internal tooth rings are spaced up and down in the sliding cavity. An upper tooth ring is fixedly installed on the upper part of the valve rod, and a lower tooth ring is coaxially and fixedly installed on the lower part of the valve rod. The above solution can replace multiple reversing valves with one valve, significantly reducing the number of valves installed, shortening the construction time, reducing construction materials, simplifying the pipeline layout, saving occupied area and space, facilitating the operator to observe the passage conditions, and significantly reducing the phenomenon of misoperation. However, when the above solution is actually used, there are still the following deficiencies: Although the multi-way valve with hierarchical adjustment proposed by the above solution has significant advantages in aspects such as hierarchical design, multi-way adjustment, and precise control of the flow rate, direction, and pressure of fluid media, it does not fully consider the requirements of operation convenience and safety in complex pipeline systems. In actual engineering applications, when a large number of valves are densely arranged in a pipeline system, the staff needs to quickly locate and adjust a specific multi-way valve, but the above multi-way valve lacks a function to warn the staff, which is likely to cause misoperation or operation delay. For example, in a large industrial process or an energy transmission network, if a certain valve needs to be adjusted urgently to cope with system fluctuations, the operator may accidentally touch adjacent equipment because it is difficult to distinguish valves with similar appearances, thereby triggering a chain of failures or safety hazards.

[0004] Based on this, the present invention discloses a multi-way valve with hierarchical adjustment. Summary of the Invention

[0005] The present invention provides a multi-way valve with hierarchical adjustment, which includes a multi-way valve body. A valve rod is assembled on the multi-way valve body. A through hole is opened at the top end of the valve rod, and a sliding rod is slidably inserted into the through hole. End caps are fixed at both ends of the sliding rod. Among them, a limiting component is arranged on the multi-way valve body. The limiting component provides a limit for the sliding rod, and the limiting component includes two rotating plates. Among them, a positioning component is provided on the multi-way valve body, and the positioning component provides positioning for one of the rotating plates; Among them, a warning unit is provided on the multi-way valve body. The warning unit includes an external component and an internal component. The external component includes an outer cylinder body. The outer cylinder body is fixed on the outer surface of the multi-way valve body through a connecting frame. A nameplate is provided on the outer peripheral surface of the outer cylinder body, and the internal component is arranged inside the outer cylinder body; As a further improvement of this technical solution, the limiting component further includes two card slots, two fixing frames and two rotating shafts. The two card slots are respectively opened at the tops of the two rotating plates. The shape of each card slot is adapted to the outer shape of the sliding rod. The two fixing frames are both fixed on the outer shell of the multi-way valve body. Each fixing frame has a U-shaped structure. The two rotating shafts are respectively rotatably installed on the two fixing frames. The two rotating plates are respectively fixedly connected to the two rotating shafts. The two rotating plates are connected by a U-shaped rod.

[0006] As a further improvement of this technical solution, the positioning component includes a positioning plate, two positioning ports, a sleeve plate, a through hole and a positioning pin. The positioning plate is fixed on the outer shell of the multi-way valve body through two connecting rods. The positioning plate has an arc-shaped structure and is coaxially arranged with the two rotating shafts. The two positioning ports are respectively opened at both ends of the positioning plate. The sleeve plate is fixedly sleeved on one of the rotating shafts. The through hole is opened at one end of the sleeve plate away from the rotating shaft. The positioning pin is inserted into the through hole and one of the positioning ports.

[0007] As a further improvement of this technical solution, two slotted holes are opened on the positioning pin, and an arc-shaped elastic sheet is arranged in each slotted hole. The middle convex position of each arc-shaped elastic sheet extends to the outside of the corresponding slotted hole.

[0008] As a further improvement of this technical solution, the external component further includes a plurality of fixing strips. The plurality of fixing strips are all fixed inside the outer cylinder body, and the plurality of fixing strips are circumferentially and arrayedly distributed.

[0009] As a further improvement of this technical solution, the internal component includes a rotating rod, a first gear, a second gear and a rotating cylinder. The rotating rod passes through the outer cylinder body and is rotatably connected to the outer cylinder body. The first gear is fixedly sleeved on one end of the rotating rod located outside the outer cylinder body. The second gear is fixedly sleeved on the other rotating shaft. The first gear and the second gear are meshed with each other. The rotating cylinder is fixed on one end of the rotating rod located inside the outer cylinder body. One end of the rotating cylinder away from the rotating rod is open. A plurality of cross bars are fixed on the outer peripheral surface of the rotating cylinder, and the plurality of cross bars are circumferentially and arrayedly distributed.

[0010] As a further improvement of this technical solution, the rotating rod, the outer cylinder body and the outer cylinder body are coaxially arranged.

[0011] As a further improvement of the present technical solution, both the fixing strip and the cross bar are made of metal materials. The cross bar has a thin sheet-like structure and can undergo elastic deformation.

[0012] As a further improvement of the present technical solution, a light source is installed inside the outer cylinder body. The light source is located inside the rotating cylinder. A plurality of first openings are formed on the outer cylinder body, and a plurality of second openings are formed on the rotating cylinder. A control component is provided on the multi-way valve body, and the control component is driven by another rotating plate.

[0013] As a further improvement of the present technical solution, the control component includes a control box, a sliding opening, a conductive strip, a conductive block, a cross bar, and a power supply module. The control box is fixed to the outer shell of the multi-way valve body through a connecting plate. The conductive strip has an arc-shaped structure and is fixed inside the control box. The sliding opening is formed on the side of the control box. The sliding rod slides in the sliding opening. One end of the sliding rod is connected to the conductive block, and the conductive block is located inside the control box. The other end of the sliding rod is connected to the corresponding rotating plate. The power supply module is installed inside the control box, and the power supply module, the conductive strip, the conductive block, and the light source are electrically connected.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During the process of the staff rotating the two rotating plates, the cross bar and the fixing strip collide continuously. Since both of them are made of metal materials, the collision will generate sound. Under the action of a plurality of cross bars and a plurality of fixing strips, continuous sound is generated inside the outer cylinder body when the rotating plate is rotated, which plays an active reminder role for the staff, making them subconsciously look at the outer cylinder body. There is a nameplate arranged on the outer cylinder body, and the nameplate has an identification, code, or symbol representing the valve. When the staff looks at the outer cylinder body, they can directly see the nameplate, and then judge whether the valve being operated is correct through the identification. If the identification is inconsistent with the valve to be adjusted, the operation of the valve stem can be stopped immediately and reset, effectively avoiding misoperation. The advantage of this design is that through sound reminder and nameplate identification, an intuitive and effective judgment basis is provided for the staff, helping them quickly and accurately confirm the valve being operated, greatly reducing the risk of misoperation, and improving work efficiency and safety; 2. The outer cylinder is provided with a plurality of first openings, and the rotating cylinder is provided with a plurality of second openings. When the rotating cylinder rotates, the second openings rotate accordingly. When the second openings are directly opposite to the first openings, the light from the light source can be irradiated through the first openings; when the second openings are staggered from the first openings, the light is blocked by the rotating cylinder. Based on the function of the above control components, the outer cylinder can emit a flashing effect when the rotating plate rotates. This flashing effect can further remind the staff. Combined with the previous sound reminder, the dual reminder mechanism can ensure that the staff can clearly see the valve logo on the nameplate when operating the valve stem. The reminder method combining sound and flash greatly improves the intensity and effectiveness of the reminder, making it easier for the staff to perceive and pay attention to key information, effectively reducing the possibility of misoperation due to negligence, and ensuring the safety and accuracy of the operation. 3. Under the limiting effect of the limit pin, the position of the sleeve is fixed, so that the rotating shaft and the corresponding rotating plate connected thereto are also fixed. Because the two rotating plates are connected by a U-shaped rod, the other rotating plate is also fixed. The two rotating plates jointly constrain the sliding rod, so that the rotating rod cannot rotate, and the valve stem cannot rotate. On the one hand, it can effectively prevent the valve from being adjusted arbitrarily by non-staff, ensuring the standardization and safety of valve operation; on the other hand, it can prevent the valve from accidentally rotating due to various external factors (such as vibration, accidental collision, etc.), providing a solid guarantee for the stable operation of valve-related work, and ensuring that the entire system can work normally and orderly according to the established requirements; 4. When the multi-way valve body needs to be adjusted, the staff first pulls out the limit pin from the through-hole to release the restriction on the sleeve plate so that it can rotate freely, and then pulls the U-shaped rod to drive the two rotating plates to rotate synchronously to a horizontal state. At this time, the shaft drives the sleeve plate to rotate to a horizontal state, and the through-hole is opposite to the positioning hole. The limit pin is inserted and fixed. After that, the two rotating plates are separated from the sliding rod. The staff pulls the sliding rod to make its end cap contact with the valve stem. The sliding rod acts as a long handle, and the sliding rod is used instead of the traditional handwheel to drive the valve stem to rotate. Its long rod structure plays a labor-saving role, which greatly reduces the operating difficulty and labor intensity of the staff, so that the staff can adjust the multi-way valve body more easily and labor-savingly, thereby improving work efficiency and convenience of operation.

Detailed implementation mode

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] The present invention provides a hierarchical adjustment multi-way valve. Refer to Figures 1-12 as shown, which includes a multi-way valve body 1. A valve rod 101 is assembled on the multi-way valve body 1. A through port 102 is opened at the top end of the valve rod 101. A sliding rod 103 is slidably inserted into the through port 102. End caps 104 are fixed at both ends of the sliding rod 103; Refer to Figures 1-2As shown in the figure, a limiting component is provided on the multi-way valve body 1. The limiting component provides limitation for the sliding rod 103. The limiting component includes two rotating plates 21. The limiting component further includes two card slots 22, two fixing brackets 23 and two rotating shafts 24. The two card slots 22 are respectively opened at the tops of the two rotating plates 21. The shape of each card slot 22 is adapted to the outer shape of the sliding rod 103. The two fixing brackets 23 are both fixed on the outer shell of the multi-way valve body 1. Each fixing bracket 23 is in a U-shaped structure. The two rotating shafts 24 are respectively rotatably installed on the two fixing brackets 23. The two rotating plates 21 are respectively fixedly connected to the two rotating shafts 24. The two rotating plates 21 are connected by a U-shaped rod; See Figures 4-6 As shown in the figure, a positioning component is provided on the multi-way valve body 1. The positioning component provides positioning for one of the rotating plates 21. The positioning component includes a positioning plate 31, two positioning ports 33, a sleeve plate 34, a through hole 35 and a positioning pin 36. The positioning plate 31 is fixed on the outer shell of the multi-way valve body 1 through two connecting rods 32. The positioning plate 31 is in an arc-shaped structure, and the positioning plate 31 and the two rotating shafts 24 are coaxially arranged. The two positioning ports 33 are respectively opened at both ends of the positioning plate 31. The sleeve plate 34 is fixedly sleeved on one of the rotating shafts 24. The through hole 35 is opened at the end of the sleeve plate 34 away from the rotating shaft 24. The positioning pin 36 is inserted into the through hole 35 and one of the positioning ports 33; When the hierarchical adjustment multi-way valve proposed by the present invention is in use, as Figure 1 shown, in the initial state, the two rotating plates 21 are both in a vertical state. At this time, the two card slots 22 are both in a position facing the sliding rod 103, that is, the sliding rod 103 is stuck in the two card slots 22, and the middle position of the sliding rod 103 is located in the through port 102. For the rotating plate 21, the position of the rotating plate 21 is restricted by the positioning component. When the rotating plate 21 is in a vertical state, the through hole 35 faces one of the positioning ports 33, and the limiting pin is inserted into the through hole 35 and this positioning port 33. Under the limiting action of the limiting pin, the position of the sleeve plate 34 will be fixed. When the sleeve plate 34 is fixed, the rotating shaft 24 connected to the sleeve plate 34 is fixed accordingly, and the corresponding rotating plate 21 is also fixed. The two rotating plates 21 are connected by a U-shaped rod. Therefore, the other rotating plate 21 will also be fixed. In this case, the two rotating plates 21 jointly provide constraints for the sliding rod 103, and the rotating rod cannot rotate, and the valve rod 101 cannot rotate either. This design can prevent the valve from being adjusted randomly by non-staff members, and at the same time prevent the valve from rotating accidentally under the influence of various external factors, ensuring the stability of the operation of the multi-way valve body 1; See Figure 7As shown, the positioning pin 36 is provided with two slots 361, each of which is provided with an arc-shaped spring piece 362, and the middle convex position of each arc-shaped spring piece 362 extends to the outside of the corresponding slot 361. For the positioning pin 36, when the positioning pin 36 is inserted into the through-hole 35 and the corresponding positioning hole 33, the sleeve plate 34 and the positioning plate 31 will squeeze the two arc-shaped spring pieces 362 on the positioning pin 36. When the positioning pin 36 is inserted into the through-hole 35 and the corresponding positioning hole 33, the sleeve plate 34 and the positioning plate 31 will squeeze the two arc-shaped spring pieces 362 on the positioning pin 36. When the positioning pin 36 is plugged into place, the two arc-shaped spring pieces 362 support the sleeve plate 34 and the positioning plate 31 under the action of their own elastic force. Under the tightening action of the two arc-shaped spring pieces 362, the positioning pin 36 can be fixed in the through-hole 35 and the corresponding positioning hole 33. This design can prevent the positioning pin 36 from falling off easily, thereby ensuring the positioning effect of the positioning pin 36 on the two rotating plates 21. When the multi-way valve body 1 needs to be adjusted, the staff first pulls out the limit pin from the through-hole 35. Without the limiting effect of the limit pin, the sleeve plate 34 can rotate freely. Then the staff pulls the U-shaped rod to make the U-shaped rod drive the two rotating plates 21 to rotate synchronously until the two rotating plates 21 rotate to a horizontal state. In this process, one of the rotating shafts 24 will drive the sleeve plate 34 to rotate, so that the sleeve plate 34 also rotates to a horizontal state. When the sleeve plate 34 is horizontal, the through-hole 35 is just opposite to the other positioning hole 33. At this time, the staff inserts the limit pin into the through-hole 35 and the corresponding positioning hole 33, and uses the limit pin to provide restriction on the two rotating plates 21. When the two rotating plates 21 are separated from the sliding rod 103, the two rotating plates 21 no longer provide a constraint for the sliding rod 103. At this time, the staff pulls the sliding rod 103 until one of the end caps 104 moves to a position in contact with the valve stem 101, such as Figure 2 As shown, in this case, the sliding rod 103 can act as a long handle, and the staff uses the sliding rod 103 to rotate the valve. The long rod-shaped structure of the sliding rod 103 saves the staff effort, replacing the traditional hand wheel driving the valve stem 101 to rotate, so that the staff can adjust the multi-way valve body 1 more easily and labor-savingly; See also Figures 8-11 As shown, a warning unit is provided on the multi-way valve body 1, and the warning unit includes an external component and an internal component. The external component includes an outer cylinder 41, and the outer cylinder 41 is fixed to the outer surface of the multi-way valve body 1 through a connecting frame 42. A nameplate 43 is provided on the outer peripheral surface of the outer cylinder 41. The external component also includes a plurality of fixing strips 44, and the plurality of fixing strips 44 are all fixed inside the outer cylinder 41, and the plurality of fixing strips 44 are distributed in a circumferential array. See also Figure 9 and Figure 11As shown in the figure, the internal components are arranged inside the outer cylinder body 41. The internal components include a rotating rod 51, a first gear 52, a second gear 53 and a rotating cylinder 54. The rotating rod 51 passes through the outer cylinder body 41 and is rotatably connected to the outer cylinder body 41. The first gear 52 is fixedly sleeved on one end of the rotating rod 51 located outside the outer cylinder body 41. The second gear 53 is fixedly sleeved on another rotating shaft 24. The first gear 52 and the second gear 53 are meshed with each other. The rotating cylinder 54 is fixed to one end of the rotating rod 51 located inside the outer cylinder body 41. One end of the rotating cylinder 54 away from the rotating rod 51 is open. A plurality of cross bars 55 are fixed on the outer peripheral surface of the rotating cylinder 54. Both the fixing bar 44 and the cross bar 55 are made of metal materials. The cross bar 55 is in a thin sheet structure and can undergo elastic deformation. The plurality of cross bars 55 are arranged in a circumferential array. The rotating rod 51, the outer cylinder body 41 and the outer cylinder body 41 are coaxially arranged. See Figures 9-11 As shown in the figure, a light source 61 is installed inside the outer cylinder body 41. The light source 61 is located inside the rotating cylinder 54. A plurality of first openings 62 are formed in the outer cylinder body 41. A plurality of second openings 63 are formed in the rotating cylinder 54. A control component is arranged on the multi-way valve body 1 and is driven by another rotating plate 21. The control component includes a control box 71, a sliding opening 73, a conductive bar 74, a conductive block 75, a cross bar 76 and a power supply module 77. The control box 71 is fixed to the outer shell of the multi-way valve body 1 through a connecting plate 72. The conductive bar 74 is in an arc structure and is fixed inside the control box 71. The sliding opening 73 is formed in the side surface of the control box 71. A sliding rod slides in the sliding opening 73. One end of the sliding rod is connected to the conductive block 75. The conductive block 75 is located inside the control box 71. The other end of the sliding rod is connected to the corresponding rotating plate 21. The power supply module 77 is installed inside the control box 71. The power supply module 77, the conductive bar 74, the conductive block 75 and the light source 61 are electrically connected. During the process of the staff rotating the two rotating plates 21, the warning unit operates to play a warning role for the staff, reminding the staff to judge whether the valve being operated is the correct valve. Specifically, when the two rotating plates 21 rotate, the two rotating shafts 24 rotate accordingly. One of the rotating shafts 24 can drive the second gear 53 to rotate. When the second gear 53 rotates, the first gear 52 meshed with it rotates accordingly. When the first gear 52 rotates, it will drive the rotating rod 51 to rotate, and the outer cylinder body 41 connected to the rotating rod 51 rotates accordingly. A plurality of cross bars 55 are arranged on the outer peripheral surface of the rotating cylinder 54, and a plurality of fixing bars 44 are arranged on the inner surface of the outer cylinder body 41. As Figures 9 to 11As shown, during the rotation of the outer cylinder body 41, continuous collisions occur between several cross bars 55 and several fixed bars 44. Since both the cross bars 55 and the fixed bars 44 are made of metal materials, sounds will be generated when they collide. Based on the above process, under the action of several cross bars 55 and several fixed bars 44, when the two rotating plates 21 rotate, continuous sounds will be emitted inside the outer cylinder body 41. This kind of sound can play an active reminder role for the staff, making the staff subconsciously look towards the position of the outer cylinder body 41. A nameplate 43 is arranged on the outer cylinder body 41, and on the nameplate 43, there are signs, codes or designations representing the valve. When the staff looks at the outer cylinder body 41, they can directly see the nameplate 43. In this case, the staff can judge whether the multi-way valve body 1 being operated is the correct multi-way valve body 1 through the signs on the nameplate 43. If the signs are inconsistent with the multi-way valve body 1 that needs to be adjusted, the staff can immediately stop the operation of the valve stem 101 and immediately reset the valve stem 101, effectively avoiding the occurrence of misoperation; Further, when the two rotating plates 21 rotate, one of the rotating plates 21 can drive the conductive block 75 to rotate through the cross bar 76. When the rotating plate 21 is in the vertical state or the horizontal state, the cross bar 76 is respectively located at both ends of the sliding port 73, and the conductive blocks 75 are respectively located at both ends of the conductive strip 74. At this time, the conductive blocks 75 and the conductive strip 74 are in a non-contact state, and the light source 61 will not be powered on and emit light. When the rotating plate 21 is in a rotating motion, the conductive block 75 rotates accordingly and rotates to a state of contacting the conductive strip 74. When the two are in contact, the light source 61 will be powered on and emit light. In addition, several first openings 62 are opened on the outer cylinder body 41, and several second openings 63 are opened on the rotating cylinder 54. During the rotation of the rotating cylinder 54, several second openings 63 will rotate accordingly. When several second openings 63 are respectively aligned with several first openings 62, the light emitted by the light source 61 can be irradiated through several first openings 62. When several second openings 63 and several first openings 62 are respectively staggered, the light emitted by the light source 61 will be blocked by the rotating cylinder 54 and cannot be irradiated. Based on the above process, under the action of the control component, when the rotating plate 21 rotates, the outer cylinder body 41 can emit a flashing effect. The flashing effect can further play a reminder role for the staff, and at the same time, combined with the above sound reminder, it is ensured that the staff can see the valve signs on the nameplate 43 when operating the valve stem 101; It should be noted that the power supply module 77 provides electrical energy for the light source 61. The circuit connection manner between the power supply module 77, the conductive strip 74, the conductive block 75 and the light source 61 is an existing technology and is not shown in the figure, so no more details will be described here.
