Description

Technical Field

[0001] This invention relates to the field of multi-way valve technology, and more specifically, to a tiered regulating multi-way valve. Background Technology

[0002] The layered regulating multi-directional valve is a valve device with an innovative structure. Through its layered design and multi-directional regulating function, it achieves precise control over the flow rate, direction, and pressure of fluid media.

[0003] A search revealed a Chinese patent, CN203627918U, for a layered regulating multi-directional valve. The valve includes a base, valve body, valve cover, valve core, and a rotary wheel. The valve body is coaxially fixed to the base, and the valve cover is coaxially mounted on the upper end of the valve body. A valve core is rotatably mounted within the valve body, and a valve stem is vertically and coaxially mounted on the valve core. The valve core consists of upper and lower layers, with symmetrically opposite semi-open channels at the upper and lower positions corresponding to the valve body. A vertical sliding cavity is formed in the middle of the valve core, containing multiple internal toothed rings spaced apart. An upper toothed ring is fixed to the upper part of the valve stem, and a lower toothed ring is coaxially fixed to the lower part of the valve stem. This solution uses one valve to replace multiple directional valves, significantly reducing the number of valves required, shortening construction time, reducing construction materials, simplifying pipeline layout, saving area and space, facilitating operator observation of the passage, and significantly reducing misoperation. However, in practical use, the above solution still has the following shortcomings:

[0004] While the layered regulating multi-way valve proposed in the above scheme has significant advantages in terms of layered design, multi-directional regulation, and precise control of fluid medium flow, direction, and pressure, it does not fully consider the operational convenience and safety requirements of complex pipeline systems. In practical engineering applications, when a large number of valves are densely arranged in a pipeline system, operators need to quickly locate and adjust specific multi-way valves. However, the aforementioned multi-way valves lack the function of warning operators, which can easily lead to misoperation or operational delays. For example, in large industrial processes or energy transmission networks, if a valve needs to be adjusted urgently to cope with system fluctuations, operators may accidentally touch adjacent equipment because they cannot distinguish valves with similar appearances, thereby causing cascading failures or safety hazards.

[0005] Based on this, the present invention discloses a layered regulating multi-directional valve. Summary of the Invention

[0006] The present invention provides a layered regulating multi-way valve, which includes a multi-way valve body, a valve stem mounted on the multi-way valve body, a through-hole opened at the top of the valve stem, a sliding rod slidably inserted into the through-hole, and end caps fixed at both ends of the sliding rod;

[0007] The multi-way valve body is provided with a limit assembly, which provides a limit for the sliding rod and includes two rotating plates.

[0008] The multi-way valve body is provided with a positioning component, which provides positioning for one of the rotating plates;

[0009] The multi-way valve body is provided with a warning unit, which includes an external component and an internal component. The external component includes an outer cylinder, which is fixed to the outer surface of the multi-way valve body by a connecting frame. A nameplate is provided on the outer circumferential surface of the outer cylinder, and the internal component is arranged inside the outer cylinder.

[0010] As a further improvement to this technical solution, the limiting component also includes two slots, two fixing brackets, and two rotating shafts. The two slots are respectively opened on the top of the two rotating plates, and the shape of each slot is adapted to the shape of the sliding rod. The two fixing brackets are fixed on the outer shell of the multi-way valve body, and each fixing bracket has a U-shaped structure. The two rotating shafts are respectively rotatably mounted on the two fixing brackets. The two rotating plates are respectively fixedly connected to the two rotating shafts, and the two rotating plates are connected by a U-shaped rod.

[0011] As a further improvement to 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 to the outer shell of the multi-way valve body by 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 the 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.

[0012] As a further improvement to this technical solution, the positioning pin has two slots, each slot is provided with an arc-shaped spring piece, and the central protrusion of each arc-shaped spring piece extends to the outside of the corresponding slot.

[0013] As a further improvement to this technical solution, the external component also includes several fixing strips, all of which are fixed inside the outer cylinder and are arranged in a circumferential array.

[0014] As a further improvement to this technical solution, the internal components include a rotating rod, a first gear, a second gear, and a rotating cylinder. The rotating rod passes through the outer cylinder and is rotatably connected to the outer cylinder. The first gear is fixedly sleeved on the end of the rotating rod located outside the outer cylinder. The second gear is fixedly sleeved on another rotating shaft. The first gear and the second gear mesh with each other. The rotating cylinder is fixed on the end of the rotating rod located inside the outer cylinder. The end of the rotating cylinder away from the rotating rod is open. Several horizontal bars are fixed on the outer circumferential surface of the rotating cylinder, and the several horizontal bars are distributed in a circumferential array.

[0015] As a further improvement to this technical solution, the rotating rod, the outer cylinder, and the outer cylinder are arranged coaxially.

[0016] As a further improvement to this technical solution, both the fixing strip and the crossbar are made of metal material, the crossbar has a thin sheet structure, and the crossbar can undergo elastic deformation.

[0017] As a further improvement to this technical solution, a light source is installed inside the outer cylinder, the light source is located inside the rotating cylinder, a plurality of first openings are opened on the outer cylinder, a plurality of second openings are opened on the rotating cylinder, and a control component is provided on the multi-way valve body, the control component being driven by another rotating plate.

[0018] As a further improvement to this technical solution, the control component includes a control box, a sliding port, a conductive strip, a conductive block, a crossbar, and a power supply module. The control box is fixed to the outer shell of the multi-way valve body via a connecting plate. The conductive strip has an arc-shaped structure and is fixed inside the control box. The sliding port is opened on the side of the control box, and the sliding rod slides in the sliding port. One end of the sliding rod is connected to the conductive block, which is located inside the control box. The other end of the sliding rod is connected to a corresponding rotating plate. The power supply module is installed inside the control box, and the power supply module, conductive strip, conductive block, and light source are electrically connected.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. During the rotation of the two rotating plates, the horizontal bars and fixed bars collide continuously. Since both are made of metal, the collision produces a sound. Under the action of several horizontal bars and several fixed bars, the outer cylinder continuously emits sounds when the rotating plates are rotated, which serves as an active reminder to the operator, causing them to subconsciously look at the outer cylinder. The outer cylinder is equipped with a nameplate, which has the identification, code, or symbol representing the valve. When the operator looks at the outer cylinder, they can directly see the nameplate and then judge whether the valve being operated is correct based on the identification. If the identification does not match the valve to be adjusted, the valve stem operation can be stopped immediately and reset, effectively avoiding misoperation. The advantage of this design is that, through sound reminders and nameplate identification, it provides the operator with intuitive and effective judgment basis, helping them to quickly and accurately identify the valve being operated, greatly reducing the risk of misoperation and improving work efficiency and safety.

[0021] 2. The outer cylinder has several first openings, and the rotating cylinder has several second openings. When the rotating cylinder rotates, the second openings rotate accordingly. When the second opening is directly opposite the first opening, light from the light source can shine through the first opening. When the second opening is misaligned with the first opening, the light is blocked by the rotating cylinder. Based on the function of the above-mentioned 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 markings on the nameplate when operating the valve stem. By combining sound and flashing reminders, the intensity and effectiveness of the reminders are greatly improved, making it easier for staff to notice and pay attention to key information, effectively reducing the possibility of misoperation due to negligence, and ensuring the safety and accuracy of operation.

[0022] 3. Under the constraint of the limit pin, the position of the sleeve plate is fixed, which in turn fixes the connected rotating shaft and the corresponding rotating plate. Since the two rotating plates are connected by a U-shaped rod, the other rotating plate is also fixed. The two rotating plates together constrain the sliding rod, preventing the rotating rod from rotating and thus the valve stem from rotating. On the one hand, this effectively prevents the valve from being arbitrarily adjusted by non-operators, ensuring the standardization and safety of valve operation. On the other hand, it prevents the valve from rotating unexpectedly 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 operate normally and orderly according to the established requirements.

[0023] 4. When adjusting the multi-way valve body, the operator first pulls out the limit pin from the through-hole to release the restriction on the sleeve plate, allowing it to rotate freely. Then, the operator pulls the U-shaped rod to drive the two rotating plates to rotate synchronously to a horizontal position. At this time, the shaft drives the sleeve plate to rotate to a horizontal position, with the through-hole aligned with the positioning port. The limit pin is then inserted and fixed. After that, the two rotating plates separate from the sliding rod. The operator pulls the sliding rod so that its end cap contacts the valve stem. The sliding rod acts as a long handle, using it to drive the valve stem rotation instead of the traditional handwheel. Its long rod structure saves effort, greatly reducing the operator's operational difficulty and labor intensity, allowing the operator to adjust the multi-way valve body more easily and effortlessly, improving work efficiency and operational convenience.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This invention provides a tiered regulating multi-directional valve, see [link / reference]. Figures 1-12 As shown, it includes a multi-way valve body 1, a valve stem 101 is mounted on the multi-way valve body 1, a through port 102 is opened at the top of the valve stem 101, a sliding rod 103 is slidably inserted into the through port 102, and end caps 104 are fixed at both ends of the sliding rod 103.

[0040] See Figures 1-2 As shown, a limit assembly is provided on the valve body 1 of the multi-way valve. The limit assembly provides a limit for the sliding rod 103. The limit assembly includes two rotating plates 21, two slots 22, two fixing brackets 23 and two rotating shafts 24. The two slots 22 are respectively opened on the top of the two rotating plates 21. The shape of each slot 22 is adapted to the shape of the sliding rod 103. The two fixing brackets 23 are fixed on the outer shell of the valve body 1 of the multi-way valve. Each fixing bracket 23 has a U-shaped structure. The two rotating shafts 24 are respectively rotatably mounted 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 to each other by a U-shaped rod.

[0041] See Figures 4-6 As shown, a positioning assembly is provided on the valve body 1 of the multi-way valve. The positioning assembly provides positioning for one of the rotating plates 21. The positioning assembly includes a positioning plate 31, two positioning ports 33, a sleeve plate 34, a through port 35, and a positioning pin 36. The positioning plate 31 is fixed to the outer shell of the valve body 1 of the multi-way valve by two connecting rods 32. The positioning plate 31 has an arc-shaped structure and is coaxially arranged with the two rotating shafts 24. 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 port 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 port 35 and one of the positioning ports 33.

[0042] The layered regulating multi-directional valve proposed in this invention, when in use, such as Figure 1As shown, in the initial state, both rotating plates 21 are vertical, and both slots 22 are directly opposite the sliding rod 103, meaning the sliding rod 103 is engaged in both slots 22, with the middle of the sliding rod 103 located in the through-hole 102. The position of the rotating plate 21 is restricted by the positioning assembly. When the rotating plate 21 is vertical, the through-hole 35 is directly opposite one of the positioning holes 33, and a limiting pin is inserted into both the through-hole 35 and the positioning hole 33. Under the restriction of the limiting pin, the position of the sleeve 34 is fixed. When the sleeve 34 is fixed, the rotating shaft 24 connected to the sleeve 34 is also fixed, and the corresponding rotating plate 21 is also fixed. The two rotating plates 21 are connected by a U-shaped rod, so the other rotating plate 21 will also be fixed. In this case, the two rotating plates 21 together provide constraint on the sliding rod 103, so the rotating rod cannot rotate and the valve stem 101 cannot rotate. This design can prevent the valve from being arbitrarily adjusted by non-operators, and at the same time prevent the valve from rotating unexpectedly under the influence of various external factors, ensuring the stability of the multi-way valve body 1.

[0043] See Figure 7 As shown, the positioning pin 36 has two slots 361, and each slot 361 is provided with an arc-shaped spring piece 362. The central protrusion of each arc-shaped spring piece 362 extends to the outside of the corresponding slot 361. 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 place, the two arc-shaped spring pieces 362 press against the sleeve plate 34 and the positioning plate 31 under their own elastic force. Under the pressing 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 easily falling off and ensure the positioning effect of the positioning pin 36 on the two rotating plates 21.

[0044] When adjusting the valve body 1 of the multi-way valve, the operator first pulls out the limiting pin from the through-hole 35. Without the limiting pin's restraining effect, the sleeve 34 can rotate freely. Next, the operator pulls the U-shaped rod, causing it to drive the two rotating plates 21 to rotate synchronously until they reach a horizontal position. During this process, one of the rotating shafts 24 will drive the sleeve 34 to rotate, causing it to also reach a horizontal position. When the sleeve 34 is horizontal, the through-hole 35 is directly aligned with the other positioning port 33. At this point, the operator inserts the limiting pin into the through-hole 35 and the corresponding positioning port 33, using the limiting pin to restrain the two rotating plates 21. When the two rotating plates 21 separate from the sliding rod 103, they no longer restrain the sliding rod 103. The operator then pulls the sliding rod 103 until one of the end caps 104 moves to a position contacting the valve stem 101. Figure 2 As shown, in this case, the sliding rod 103 can act as a long handle. The operator uses the sliding rod 103 to turn the valve. The long rod-like structure of the sliding rod 103 saves the operator effort and replaces the traditional handwheel-driven valve stem 101 rotation method, making it easier and less strenuous for the operator to adjust the multi-way valve body 1.

[0045] See Figures 8-11 As shown, a warning unit is provided on the multi-way valve body 1. The warning unit includes an external component and an internal component. The external component includes an outer cylinder 41, which is fixed to the outer surface of the multi-way valve body 1 by a connecting bracket 42. A nameplate 43 is provided on the outer circumferential surface of the outer cylinder 41. The external component also includes several fixing strips 44, which are all fixed inside the outer cylinder 41 and are arranged in a circumferential array.

[0046] See Figure 9 and Figure 11 As shown, the internal components are arranged inside the outer cylinder 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 41 and is rotatably connected to the outer cylinder 41. The first gear 52 is fixedly sleeved on the end of the rotating rod 51 located outside the outer cylinder 41. The second gear 53 is fixedly sleeved on another rotating shaft 24. The first gear 52 and the second gear 53 mesh with each other. The rotating cylinder 54 is fixed on the end of the rotating rod 51 located inside the outer cylinder 41. The end of the rotating cylinder 54 away from the rotating rod 51 is open. Several horizontal bars 55 are fixed on the outer circumferential surface of the rotating cylinder 54. Both the fixing bars 44 and the horizontal bars 55 are made of metal. The horizontal bars 55 have a thin sheet structure and can undergo elastic deformation. Several horizontal bars 55 are distributed in a circumferential array. The rotating rod 51, the outer cylinder 41, and the outer cylinder 41 are arranged coaxially.

[0047] See Figures 9-11As shown, a light source 61 is installed inside the outer cylinder 41. The light source 61 is located inside the rotating cylinder 54. Several first openings 62 are opened on the outer cylinder 41, and several second openings 63 are opened on the rotating cylinder 54. A control component is provided on the multi-way valve body 1. The control component is driven by another rotating plate 21. The control component includes a control box 71, a sliding port 73, a conductive strip 74, a conductive block 75, a crossbar 76, and a power supply module 77. The control box 71 is fixed to the outer shell of the multi-way valve body 1 by a connecting plate 72. The conductive strip 74 has an arc-shaped structure and is fixed inside the control box 71. The sliding port 73 is opened on the side of the control box 71. The sliding rod slides in the sliding port 73. One end of the sliding rod is connected to the conductive block 75, which 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 strip 74, the conductive block 75, and the light source 61 are electrically connected.

[0048] As the operator rotates the two rotating plates 21, the warning unit operates, serving as a warning to the operator and reminding them to determine whether the valve being operated is correct. Specifically, when the two rotating plates 21 rotate, the two rotating shafts 24 rotate accordingly. One of the rotating shafts 24 drives the second gear 53 to rotate. When the second gear 53 rotates, the first gear 52 meshing with it rotates accordingly. The rotation of the first gear 52, in turn, drives the rotating rod 51 to rotate. The outer cylinder 41 connected to the rotating rod 51 rotates accordingly. The outer circumference of the rotating cylinder 54 is arranged with several horizontal bars 55, and the inner surface of the outer cylinder 41 is arranged with several fixed bars 44, such as... Figures 9 to 11 As shown, during the rotation of the outer cylinder 41, several horizontal bars 55 and several fixed bars 44 will continuously collide. Since both the horizontal bars 55 and the fixed bars 44 are made of metal, they will make a sound when they collide. Based on the above process, under the action of the several horizontal bars 55 and several fixed bars 44, the two rotating plates 21 will make a sound inside the outer cylinder 41 when they rotate. This sound can serve as an active reminder to the staff, making them subconsciously look towards the position of the outer cylinder 41. A nameplate 43 is arranged on the outer cylinder 41. The nameplate 43 is set with the identification, code or symbol representing the valve. When the staff looks at the outer cylinder 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 by the identification on the nameplate 43. If the identification is 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 misoperation.

[0049] Furthermore, when the two rotating plates 21 rotate, one of the rotating plates 21 can drive the conductive block 75 to rotate via the crossbar 76. When the rotating plate 21 is in a vertical or horizontal state, the crossbar 76 is located at both ends of the sliding opening 73, and the conductive block 75 is located at both ends of the conductive strip 74. At this time, the conductive block 75 and the conductive strip 74 are not in contact with each other, and the light source 61 will not be energized and illuminate. When the rotating plate 21 is rotating, the conductive block 75 rotates accordingly and rotates until it comes into contact with the conductive strip 74. When the two come into contact, the light source 61 will be energized and illuminate. In addition, the outer cylinder 41 has several first openings 62, and the rotating cylinder 54 has several second openings 63. During the rotation of the rotating cylinder 54, several second openings 63 will rotate accordingly. When several second openings 63 are directly opposite several first openings 62, the light emitted by the light source 61 can shine through several first openings 62. When several second openings 63 are offset from several first openings 62, the light emitted by the light source 61 will be blocked by the rotating cylinder 54 and cannot shine through. Based on the above process, under the action of the control component, when the rotating plate 21 rotates, the outer cylinder 41 can emit a flashing effect. The flashing effect can further remind the staff. At the same time, combined with the above sound reminder, it ensures that the staff can see the valve marking on the nameplate 43 when operating the valve stem 101.

[0050] It should be noted that the power supply module 77 provides power to the light source 61. The circuit connection between the power supply module 77, the conductive strip 74, the conductive block 75 and the light source 61 is existing technology and is not shown in the figure. It will not be described in detail here.

[0051] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
