Description

Technical Field

[0001] This application relates to the technical field of valves, and in particular to a multi-way plunger valve. Background Art

[0002] A multi-way plunger valve is a type of valve that can change the flow direction of the medium.

[0003] In related art, a multi-way plunger valve includes a valve body. An inlet pipe, a first outlet pipe, a second outlet pipe, and a third outlet pipe are connected to the valve body. The first connecting pipe is coaxially arranged with the inlet pipe, the second outlet pipe is perpendicularly connected to the inlet pipe, and the third outlet pipe is perpendicularly connected to the inlet pipe.

[0004] When the fluid flows from the inlet pipe to the second outlet pipe or the third outlet pipe, the perpendicular connection generates a large local resistance to the fluid. The flow direction of the fluid changes sharply at the right angle, resulting in a large loss of fluid kinetic energy and a decrease in fluid transportation efficiency. Summary of the Invention

[0005] In order to improve the transportation efficiency of the fluid passing through the multi-way plunger valve, this application provides a multi-way plunger valve.

[0006] A multi-way plunger valve provided by this application adopts the following technical solution: A multi-way plunger valve includes a first fixed pipe. A first fixed hole is formed in the end face of the first fixed pipe. An inlet pipe is connected to the end face of the first fixed pipe. A first outlet pipe is arranged on the outer circumferential surface of the first fixed pipe. A first outlet hole is formed at one end of the first outlet pipe away from the first fixed pipe. A first plugging mechanism capable of plugging the first outlet hole is arranged at one end of the first fixed pipe away from the inlet pipe. A second fixed pipe is arranged on the outer circumferential surface of the first fixed pipe. A second fixed hole communicating with the first fixed hole is formed in the end face of the second fixed pipe away from the first fixed pipe. The flow direction of the fluid in the first fixed hole and the flow direction of the fluid in the second fixed hole form an acute angle. A second outlet pipe is arranged on the outer circumferential surface of the first fixed pipe. A second outlet hole is formed at one end of the second outlet pipe away from the second fixed pipe. A second plugging mechanism capable of plugging the second outlet hole is arranged at one end of the second fixed pipe away from the inlet pipe.

[0007] By adopting the above technical solution, the fluid is conveyed from the feed pipe into the first fixing hole. When the first plugging mechanism releases the plugging of the first discharge hole, the fluid can be conveyed from the first fixing hole into the first discharge hole and then from the first discharge hole into the pipe connected to the first discharge hole; when the second plugging mechanism releases the plugging of the second discharge hole, the fluid can be conveyed from the second fixing hole into the second discharge hole and then from the second discharge hole into the pipe connected to the second discharge hole; the flow direction of the fluid in the first fixing hole forms an acute angle with the flow direction of the fluid in the second fixing hole, reducing the resistance of the fluid conveyed from the first fixing hole to the second fixing hole, making the flow rate of the fluid not easy to decrease, and improving the conveying efficiency of the fluid.

[0008] Optionally, the second plugging mechanism includes a mounting frame arranged on the side of the second fixing pipe away from the feed pipe and a plugging rod inserted into the second fixing hole. A guiding pipe is rotatably connected in the mounting frame. One end of the plugging rod away from the first fixing pipe is rotatably connected with a rotating rod inserted into the guiding pipe. A guiding member is arranged on the outer circumferential surface of the rotating rod. A spiral sliding hole capable of accommodating the guiding member is formed in the inner wall of the guiding pipe. The guiding member is slidably arranged in the spiral sliding hole. A second driving assembly capable of driving the plugging rod to rotate is arranged on the first fixing pipe.

[0009] By adopting the above technical solution, the second driving assembly drives the rotating rod to rotate, so that the guiding member moves in the spiral sliding groove, making the plugging rod move towards the direction of the first fixing hole, and the plugging rod plugs the second discharge hole; conversely, the second driving assembly drives the rotating rod to rotate in the reverse direction and moves along the axis direction of the second fixing hole, so that the plugging rod no longer plugs the second discharge hole.

[0010] Optionally, a first limiting hole and a second limiting hole are formed in the outer circumferential surface of the guiding pipe. The spiral sliding hole is located between the first limiting hole and the second limiting hole. The end of the spiral sliding hole away from the plugging rod is communicated with the first limiting hole, and the end of the spiral sliding hole close to the plugging rod is communicated with the second limiting hole.

[0011] By adopting the above technical solution, when the guiding member is in the first limiting hole / second limiting hole, the rotating rod is not easy to rotate relative to the guiding pipe, avoiding the movement of the rotating rod and the plugging rod in the first fixing groove when the staff does not operate the driving assembly.

[0012] Optionally, a guiding arc surface is formed on the end face of the plugging rod away from the rotating rod.

[0013] By adopting the above technical solution, the driving assembly drives the plugging rod to move, so that the plugging rod no longer plugs the first discharge hole. After the fluid enters the first fixing groove from the feed pipe, the fluid in the first fixing groove is guided towards the first discharge hole through the guiding arc surface, reducing the resistance of the fluid conveyed from the first fixing pipe to the first discharge pipe and improving the speed of the fluid sent to the first discharge pipe.

[0014] Optionally, the first plugging mechanism includes a mounting post connected to the side of the first fixed pipe away from the feed pipe. On the side of the mounting post away from the first fixed pipe, there is a mounting member. An installation rod is passed through the mounting member. On the side of the installation rod facing the feed pipe, there is a valve rod that can be inserted into the first fixing hole. A guide plate is sleeved outside the installation rod. A punching hole through which the mounting post can pass is opened on the guide plate. A convex block is arranged on the outer circumferential surface of the installation rod. A groove into which the convex block can be inserted is opened on the inner wall of the punching hole. A first driving component for driving the installation rod to rotate is arranged on the mounting member; the first driving component includes a mounting cover arranged on the side of the mounting member away from the first fixed pipe. An installation groove is opened on the end face of the mounting cover facing the mounting member. A support plate is arranged in the installation groove. A second bevel gear is rotatably connected to the side of the support plate away from the mounting member. A driving rod is rotatably connected to the mounting cover. A first bevel gear is sleeved outside the driving rod. The first bevel gear meshes with the second bevel gear.

[0015] By adopting the above technical solution, when the driving rod rotates, the driving rod drives the first bevel gear to rotate. Since the first bevel gear meshes with the second bevel gear, the first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the installation rod to rotate. Since the guide plate is sleeved outside the installation rod and the mounting post, and the convex block is in the groove, the installation rod cannot rotate, so that the installation rod can only move along the axis direction of the first fixing hole, that is, the valve rod moves along the axis direction of the first fixing hole, so that the valve rod opens and closes the first discharge hole.

[0016] Optionally, a one-way mechanism is arranged on the feed pipe. The one-way mechanism includes an operation pipe arranged at one end of the feed pipe away from the first fixed pipe. A counterbore is opened on the end of the operation pipe facing the feed pipe. A receiving groove is opened on the bottom wall of the counterbore. A receiving hole is opened on the bottom wall of the receiving groove. An operation disk is arranged in the receiving hole. A jack and an operation hole are opened on the end face of the operation disk facing the operation hole. An insertion rod is passed through the jack. On the end face of the insertion rod away from the first fixed pipe, there is a plugging disk that can plug the receiving hole. A spring is arranged between the plugging disk and the operation disk. The spring is in a compressed state.

[0017] By adopting the above technical solution, when the fluid enters the operation pipe from the end away from the feed pipe, the fluid exerts a force on the plugging disk, so that the plugging disk and the plugging rod move towards the first fixed pipe, and at the same time, the spring is compressed and deformed, so that the plugging disk no longer plugs the receiving hole, and the fluid enters the receiving groove from the receiving hole.

[0018] Optionally, a folding pipe is sleeved outside the insertion rod. The spring is located inside the insertion rod. One end of the folding pipe is fixedly connected to the plugging disk, and the other end of the folding pipe is fixedly connected to the operation disk.

[0019] By adopting the above technical solution, the folding tube is sleeved outside the spring and the insertion rod to protect the spring and the insertion rod, so that the spring and the insertion rod do not contact the fluid; if impurities in the fluid remain on the folding tube, when the plugging disc is driven to reciprocate along the axis of the plugging rod, the folding tube folds or unfolds, loosening the impurities adhered to the folding tube.

[0020] Optionally, a deformable diaphragm is arranged on the end face of the operation disc away from the plugging disc. The outer edge of the side of the diaphragm facing the plugging disc is fixedly connected to the operation disc. One end of the diaphragm facing the plugging disc is attached to the operation disc. A through hole through which the insertion rod can pass is provided on the side of the diaphragm facing the operation hole, and a forming hole staggered from the operation hole is provided on the diaphragm.

[0021] By adopting the above technical solution, when the fluid is conveyed from the side of the operation disc close to the accommodation hole to the side of the operation disc away from the accommodation hole, the fluid drives the diaphragm to deform towards the feeding pipe direction, so that the operation hole communicates with the forming hole, and the fluid passes through the operation hole, the forming hole and is conveyed into the feeding pipe.

[0022] Optionally, a locking assembly for connecting the two is arranged between the feeding pipe and the operation pipe. An operation groove is provided on the inner circumferential surface of the counterbore. The operation groove penetrates the operation pipe in a direction away from the accommodation hole. A fixing groove is provided on the outer circumferential surface of the feeding pipe. The fixing groove penetrates the feeding pipe in a direction away from the first fixing pipe. The locking assembly includes a driving rack arranged in the operation groove, a linkage gear rotatably connected in the operation groove, a driven rack arranged in the fixing groove, and a clamping block arranged on the outer circumferential surface of the feeding pipe. The linkage gear is located on the side of the driving rack facing the axis of the counterbore and meshes with the driving rack. The clamping block is located on the side of the operation groove facing the first fixing pipe. The driven rack can mesh with the linkage gear. A locking hook is arranged on the side of the driving rack away from the accommodation groove. The locking hook can be hooked and matched with the clamping block.

[0023] By adopting the above technical solution, the feeding pipe is inserted into the counterbore to make the linkage gear mesh with the driven rack. The operation pipe is continuously driven to move towards the first fixing pipe. The linkage gear rolls along the driven rack, so that the linkage gear drives the driving rack to move, making the driving rack extend out of the counterbore, and the locking hook move towards the clamping block until the locking hook is hooked and matched with the clamping block, realizing the locking connection between the feeding pipe and the operation pipe.

[0024] Optionally, an unlocking ring is rotatably connected to the outer circumference of the feeding pipe. The unlocking ring is located on the side of the clamping block away from the operation pipe. An unlocking block capable of driving the locking hook to move in a direction away from the axis of the feeding pipe is arranged on the outer circumferential surface of the unlocking ring.

[0025] By adopting the above technical solution, the unlocking ring is driven to rotate. The unlocking ring drives the unlocking block to rotate synchronously. The unlocking block drives the locking hook to move away from the axis of the feed pipe, so that the locking hook no longer engages with the clamping block. The operating pipe is driven to move away from the first fixed pipe, separating the operating pipe from the feed pipe.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Fluids are transported from the feed pipe into the first fixed hole. When the first plugging mechanism releases the plugging of the first discharge hole, the fluids can be transported from the first fixed hole into the first discharge hole and then transported into the pipe connected to the first discharge hole. When the second plugging mechanism releases the plugging of the second discharge hole, the fluids can be transported from the second fixed hole into the second discharge hole and then transported into the pipe connected to the second discharge hole. The flow direction of the fluids in the first fixed hole forms an acute angle with the flow direction of the fluids in the second fixed hole, reducing the resistance of the fluids transported from the first fixed hole to the second fixed hole, making it difficult for the flow rate of the fluids to decrease, and improving the transportation efficiency of the fluids. 2. The unlocking ring and the unlocking block are provided to facilitate the staff to release the engagement between the locking hook and the clamping block. Description of the Drawings

[0070] The implementation principle of Embodiment 2 is as follows: Insert the feed pipe 3 into the counterbore 811 so that the driven rack 823 meshes with the linkage gear 822. Continue to drive the operation pipe 81 towards the first fixed pipe 1. Since the driven rack 823 cannot move, the linkage gear 822 rotates due to the driven rack 823, and the linkage gear 822 drives the driving rack 821 to extend out of the counterbore 811 until the locking hook 824 abuts against the locking chamfer. Continue to drive the operation pipe 81 towards the first fixed pipe 1, and the locking hook 824 deforms in a direction away from the axis of the feed pipe 3 until the block 825 is hooked and engaged with the locking hook 824. The fluid enters the operation pipe 81, and the fluid drives the plugging disc 85 towards the operation disc 83, so that the plugging disc 85 no longer plugs the accommodating hole 813. At the same time, the spring 86 is compressed and deformed, and the fluid enters the first chamber. The fluid in the first chamber acts on the diaphragm 88 through the operation hole 832, causing the diaphragm 88 to arch and deform towards the feed pipe 3. The fluid passes through the area formed between the diaphragm 88 and the operation disc 83 and then enters the second chamber through the forming holes 881 on the diaphragm 88. The fluid is subsequently conveyed into the feed pipe 3 and the first fixed pipe 1.
