Description
Technical Field
[0001] This utility model relates to the field of dome valve technology, and in particular to a dome valve. Background Technology
[0002] A dome valve is a device used to cut off and seal a flowing material stream, and is widely used in pneumatic conveying systems. Its main function is to ensure the filling rate of pressure tanks and provide a reliable seal under harsh conditions.
[0003] Dome valves typically operate by rotating a valve core driven by a cylinder. During use, the valve core is fixed to the cylinder. However, after prolonged use, the top of the valve core is prone to wear. This necessitates replacement, but the fixed connection between the valve core and cylinder makes replacement difficult, thus increasing the workload for operators. Utility Model Content
[0004] To solve the above problems, this utility model provides a dome valve.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dome valve, comprising a first valve body and a second valve body, wherein two mutually symmetrical rotating grooves are opened on the inner walls of the first valve body and the second valve body, and a rotating rod is rotatably arranged in each of the two rotating grooves, and a valve core is fixedly arranged on the two rotating rods. A mounting plate is fixedly arranged on the first valve body and the second valve body, and a driving cylinder is fixedly arranged on the side wall of the mounting plate. A rotating seat is fixedly arranged at the end of the piston rod of the driving cylinder, and a rotating component is rotatably arranged in the rotating seat. A connecting rod is fixedly arranged on the side wall of the rotating component, and the connecting rod passes through the mounting plate and is rotatably connected to the mounting plate. A connecting assembly for connecting the connecting rod and the rotating rod is provided between the connecting rod and the rotating rod.
[0006] By adopting the above technical solution, when the dome valve is in use, the operator drives the connecting rod to rotate by driving the cylinder (during this process, the rotating part and the rotating seat rotate relative to each other), thereby causing the rotating rod to rotate under the action of the connecting rod, so that the valve core rotates under the action of the rotating rod. After the valve core has been used for a long time, the operator needs to replace the valve core. The operator can install and separate the connecting rod and the rotating rod through the connecting assembly, thereby reducing the difficulty of the operator replacing the valve core and thus reducing the difficulty of the operator's work.
[0007] Furthermore, the rotating rod has an installation groove on its side wall, and a first fixing groove is formed on the inner wall of the installation groove. The connecting assembly includes an installation rod that is slidably disposed in the installation groove. A second fixing groove is formed on the side wall of the installation rod, which is directly opposite to the first fixing groove. The connecting assembly also includes a fixing block that is slidably disposed in the first fixing groove and a fixing spring that is fixedly disposed on the side wall of the fixing block. The fixing block is slidably connected to the second fixing groove. The other end of the fixing spring is fixedly disposed on the inner wall of the first fixing groove. A first inclined surface is formed on the edge of the side wall of the fixing block away from the fixing spring where it intersects with one of the adjacent side walls. The installation rod and the connecting rod are connected to each other.
[0008] By adopting the above technical solution, when workers need to install the connecting rod and the rotating rod together, they need to slide the mounting rod into the mounting groove, gradually bringing it closer to and finally pressing it against the first inclined surface. This allows the fixing block to slide into the first fixing groove under the action of the mounting rod. Subsequently, when the first fixing groove and the second fixing groove are aligned, the fixing block slides under the action of the first spring, causing one end of the fixing block to slide into the second fixing groove. This fixes the mounting rod in the mounting groove, reducing the difficulty for workers to connect the connecting rod and the rotating rod, thus reducing the workload of the workers.
[0009] Furthermore, a sliding groove is provided on the side wall of the connecting rod, and the mounting rod is slidably connected to the sliding groove. A rotating groove is provided through the outer wall of the connecting rod, and a rotating component is rotatably disposed in the rotating groove. A screw is fixedly disposed on the side wall of the rotating component, and the screw is threadedly connected to the mounting rod.
[0010] By adopting the above technical solution, when workers need to disassemble the connecting rod and the rotating rod, they need to rotate the rotating component, which in turn causes the screw to rotate under the action of the rotating component. This causes the mounting rod to slide under the action of the screw, and then the fixing block moves into the first fixing groove under the action of the mounting rod. At this time, workers can quickly pull out the mounting rod to disassemble the connecting rod and the rotating rod, thereby reducing the difficulty of the work.
[0011] Furthermore, a blocking block is slidably disposed on the inner wall of the second fixing groove, and a second inclined surface is formed on the edge where the upper surface of the blocking block intersects with the side wall of one of the adjacent side walls, and the first inclined surface and the second inclined surface match each other.
[0012] By adopting the above technical solution, the blocking block reduces the probability that the fixing block will slide back into the second fixing groove when the operator quickly pulls out the installation rod, thereby improving the stability of the device.
[0013] Furthermore, a reset groove is provided on the inner wall of the second fixing groove, and a reset spring is fixedly provided on the inner wall of the reset groove. The other end of the reset spring is fixed to the blocking block.
[0014] By adopting the above technical solution, the reset spring reduces the difficulty of resetting the blocking block, thereby reducing the workload for workers.
[0015] Furthermore, a limiting groove is formed on the inner wall of the rotating groove, and a limiting component is rotatably arranged in the limiting groove, with the limiting component and the rotating component being fixed to each other.
[0016] By adopting the above technical solution, the limiting component reduces the probability of shaking when the rotating component rotates, thereby improving the stability of the device.
[0017] Furthermore, the first valve body and the second valve body are fixed to each other by nuts and bolts.
[0018] By adopting the above technical solution, the first valve body and the second valve body are fixed to each other by nuts and bolts, which reduces the difficulty for workers to disassemble and install the first valve body and the second valve body, thereby reducing the difficulty of the workers' work.
[0019] Furthermore, the outer wall of the rotating component has multiple grooves arranged in a circular array.
[0020] By adopting the above technical solution, the groove reduces the difficulty for workers to rotate the rotating parts, thereby reducing the difficulty of their work.
[0021] In summary, this utility model has the following beneficial effects:
[0022] 1. In this application, when the dome valve is in use, the operator drives the connecting rod to rotate by driving the cylinder (in this process, the rotating part and the rotating seat rotate relative to each other), thereby causing the rotating rod to rotate under the action of the connecting rod, so that the valve core rotates under the action of the rotating rod. After the valve core has been used for a long time, the operator needs to replace the valve core. The operator can install and separate the connecting rod and the rotating rod through the connecting assembly, thereby reducing the difficulty of the operator replacing the valve core and thus reducing the difficulty of the operator's work.
[0023] 2. In this application, when the worker needs to install the connecting rod and the rotating rod together, the worker needs to slide the mounting rod into the mounting groove, so that the mounting rod gradually approaches and finally presses against the first inclined surface, thereby causing the fixing block to slide into the first fixing groove under the action of the mounting rod. Subsequently, when the first fixing groove and the second fixing groove are aligned, the fixing block slides under the action of the first spring, thereby causing one end of the fixing block to slide into the second fixing groove, thus fixing the mounting rod in the mounting groove by the fixing block, thereby reducing the difficulty for the worker to connect the connecting rod and the rotating rod together, and thus reducing the difficulty of the worker's work;
[0024] 3. In this application, when the worker needs to disassemble the connecting rod and the rotating rod, the worker needs to rotate the rotating component, which in turn causes the screw to rotate under the action of the rotating component. This causes the mounting rod to slide under the action of the screw, and then the fixing block moves into the first fixing groove under the action of the mounting rod. At this time, the worker can quickly pull out the mounting rod to disassemble the connecting rod and the rotating rod, thereby reducing the difficulty of the worker's work.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0031] like Figure 1-4 As shown in the figure, this application discloses a dome valve, including a first valve body 1, a second valve body 11, a rotating rod 13, a valve core 14, a mounting plate 15, a drive cylinder 16, a rotating seat 17, a rotating component 18, a connecting rod 19, a connecting assembly 3, a rotating component 42, and a screw 43. The inner walls of the first valve body 1 and the second valve body 11 share two symmetrical rotating grooves 12. The rotating rod 13 is a round rod-shaped structure with a horizontal axis. Two rotating rods 13 are provided and rotatably disposed within the two rotating grooves 12 respectively. The valve core 14 is fixedly disposed on the two rotating rods 13. The mounting plate 15 is a rectangular plate-shaped structure and is fixedly disposed on the first valve body 1 and the second valve body 11. The drive cylinder 16 is fixedly disposed on the side wall of the mounting plate 15, with its piston rod axis horizontal. The rotating seat 17 is fixedly disposed at the end of the piston rod of the drive cylinder 16, and the rotating component 18 is rotatably disposed within the rotating seat 17. The connecting rod 19 is a round rod structure, and its axis coincides with the axis of the rotating rod 13. The connecting rod 19 is fixedly installed on the side wall of the rotating part 18, and the connecting rod 19 passes through the mounting plate 15 and is rotatably connected to the mounting plate 15.
[0032] When the dome valve is in use, the operator drives the connecting rod 19 to rotate by driving the cylinder 16 (during this process, the rotating part 18 and the rotating seat 17 rotate relative to each other), which in turn causes the rotating rod 13 to rotate under the action of the connecting rod 19, thereby causing the valve core 14 to rotate under the action of the rotating rod 13. After the valve core 14 has been used for a long time, the operator needs to replace the valve core 14. The operator can install and separate the connecting rod 19 and the rotating rod 13 through the connecting assembly 3, which reduces the difficulty of the operator replacing the valve core 14 and thus reduces the difficulty of the operator's work.
[0033] A mounting groove 2 is formed on the side wall of the rotating rod 13, and a first fixing groove 21 is formed on the inner wall of the mounting groove 2. A connecting assembly 3 is disposed between the connecting rod 19 and the rotating rod 13 to connect the connecting rod 19 and the rotating rod 13. The connecting assembly 3 includes a mounting rod 31, a fixing block 32, and a fixing spring 33. The mounting rod 31 is a round rod structure and is slidably disposed in the mounting groove 2. A second fixing groove 22 is formed on the side wall of the mounting rod 31, which is directly opposite to the first fixing groove 21. The fixing block 32 is a rectangular block structure and is slidably disposed in the first fixing groove 21. The fixing block 32 is slidably connected to the second fixing groove 22. One end of the fixing spring 33 is fixedly disposed on the side wall of the fixing block 32, and the other end of the fixing spring 33 is fixedly disposed on the inner wall of the first fixing groove 21. A first inclined surface 34 is formed on the edge of the fixing block 32 where it intersects with one of the adjacent side walls. The mounting rod 31 is connected to the connecting rod 19.
[0034] When the operator needs to install the connecting rod 19 and the rotating rod 13, the operator slides the mounting rod 31 into the mounting groove 2, causing the mounting rod 31 to gradually approach and eventually press against the first inclined surface 34. This allows the fixing block 32 to slide into the first fixing groove 21 under the action of the mounting rod 31. Subsequently, when the first fixing groove 21 and the second fixing groove 22 are aligned, the fixing block 32 slides under the action of the first spring, causing one end of the fixing block 32 to slide into the second fixing groove 22. This fixes the mounting rod 31 within the mounting groove 2, reducing the difficulty for the operator in connecting the connecting rod 19 and the rotating rod 13, thus reducing the workload.
[0035] A groove 4 is provided on the side wall of the connecting rod 19, and the mounting rod 31 is slidably connected to the groove 4. A rotating groove 41 is provided through the outer wall of the connecting rod 19. The rotating component 42 is rotatably disposed in the rotating groove 41, and its axis coincides with the axis of the connecting rod 19. The screw 43 is fixedly disposed on the side wall of the rotating component 42, and its axis coincides with the axis of the rotating component 42. The screw 43 is threadedly connected to the mounting rod 31.
[0036] When workers need to disassemble the connecting rod 19 and the rotating rod 13, they need to rotate the rotating component 42, which in turn causes the screw 43 to rotate under the action of the rotating component 42. This causes the mounting rod 31 to slide under the action of the screw 43, and then the fixing block 32 to move into the first fixing groove 21 under the action of the mounting rod 31. At this time, workers can quickly pull out the mounting rod 31 to disassemble the connecting rod 19 and the rotating rod 13, thus reducing the difficulty of the work.
[0037] To improve the stability of the device, a blocking block 5 is slidably disposed on the inner wall of the second fixing groove 22. A second inclined surface is formed on the edge where the upper surface of the blocking block 5 intersects with the side wall of one of the adjacent side walls. The first inclined surface 34 matches the second inclined surface. The blocking block 5 reduces the probability that the fixing block 32 will slide back into the second fixing groove 22 when the operator quickly pulls out the mounting rod 31, thereby improving the stability of the device.
[0038] To reduce the difficulty of the work for the staff, a reset groove 6 is provided on the inner wall of the second fixing groove 22. A reset spring 61 is fixedly installed on the inner wall of the reset groove 6, and the other end of the reset spring 61 is fixed to the blocking block 5. The reset spring 61 reduces the difficulty of resetting the blocking block 5, thereby reducing the difficulty of the work for the staff.
[0039] To improve the stability of the device, a limiting groove 7 is formed on the inner wall of the rotating groove 41, and a limiting member 71 is rotatably installed in the limiting groove 7. The limiting member 71 is fixed to the rotating member 42. The limiting member 71 reduces the probability of shaking when the rotating member 42 rotates, thereby improving the stability of the device.
[0040] To reduce the difficulty of the work for the operators, the first valve body 1 and the second valve body 11 are fixed together with nuts and bolts. This mutual fixing reduces the difficulty for operators in disassembling and assembling the first valve body 1 and the second valve body 11, thus lowering the overall workload.
[0041] To reduce the difficulty of the work for the operators, multiple grooves 8 are arranged in a circular array on the outer wall of the rotating component 42. The grooves 8 reduce the difficulty for the operators to rotate the rotating component 42, thereby reducing the difficulty of the work for the operators.
[0042] The operating principle of the dome valve in this embodiment is as follows: When the dome valve is in use, the operator drives the connecting rod 19 to rotate by driving the cylinder 16 (during this process, the rotating part 18 and the rotating seat 17 rotate relative to each other), thereby causing the rotating rod 13 to rotate under the action of the connecting rod 19, so that the valve core 14 rotates under the action of the rotating rod 13. After the valve core 14 has been used for a long time, the operator needs to replace the valve core 14. The operator can install and separate the connecting rod 19 and the rotating rod 13 through the connecting component 3, thereby reducing the difficulty of the operator replacing the valve core 14 and thus reducing the difficulty of the operator's work.
[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
