Description

Technical Field

[0001] This utility model relates to the field of high-pressure ball valve technology, specifically to a forged steel high-pressure ball valve. Background Technology

[0002] High-pressure forged steel ball valves are mainly used in long-distance natural gas pipeline transportation and urban gas pipeline systems. Due to the unique characteristics of valves used in long-distance pipelines, their design fully considers their ability to withstand pipeline stress, as well as safety, weather resistance, and long-term reliability. The sealing and structural design are unique to our company. Operation methods include manual-worm gear drive, pneumatic, electric, pneumatic / hydraulic linkage, electro / hydraulic linkage, and various special control forms.

[0003] A search revealed a forged steel high-pressure ball valve with application number CN202320036663.3, comprising a valve body, a rotating mounting seat fixed at the top center of the valve body, a rotating handle rotatably mounted in the rotating mounting seat, and a ball valve body located inside the valve body fixed to the rotating handle, through pipes fixed on both sides of the valve body, and flange connecting seats connected to the opposite ends of the through pipes via a connecting mechanism, a filter plate fixedly mounted inside the through pipe, a through hole groove opened at the bottom of the through pipe, and a rectangular holding chamber fixedly connected to the periphery of the through hole groove on the bottom outer wall of the through pipe, the rectangular holding chamber communicating with the through pipe.

[0004] In this solution, impurities are isolated by a filter plate, but no cleaning mechanism is provided for the filter plate. After long-term use, the filter holes on the filter plate are prone to clogging. In addition, the filter plate is fixedly installed inside the through pipe, making it difficult to replace the filter plate later. Based on this, this solution provides a forged steel high-pressure ball valve to solve the above-mentioned problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, a forged steel high-pressure ball valve is provided, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A forged steel high-pressure ball valve includes a valve body with a valve at the upper end. An inlet pipe and an outlet pipe are fixedly connected to the left and right sides of the valve body, respectively. A filter pipe is provided on one side of the inlet pipe, and a fixed pipe is provided inside the filter pipe. A blade holder is rotatably mounted on the right side of the fixed pipe. A vortex blade connected to the fixed pipe is provided inside the blade holder. A fixing component for fixing the blade holder is provided inside the filter pipe. A first mounting bracket and a second mounting bracket with identical structures are provided on the left end surface of the fixed pipe. A fine filter screen is fixedly mounted on the first mounting bracket, and a coarse filter screen is fixedly mounted on the second mounting bracket. A connector for engaging the first mounting bracket and the second mounting bracket is provided inside the fixed pipe. An annular groove 1 and an annular groove 2 are formed on the inner wall of the filter pipe. A rotating ring with identical structures is rotatably mounted in both annular groove 1 and annular groove 2. The two rotating rings are engaged with the first mounting bracket and the second mounting bracket, respectively.

[0008] Preferably, a flange ring 1 is fixedly connected to the inlet pipe, a flange ring 2 that is compatible with flange ring 1 is fixedly connected to one end of the filter pipe, flange ring 1 and flange ring 2 are attached to each other and fixed by bolts, and a flange ring 3 is fixedly connected to the left end of the filter pipe.

[0009] Preferably, several sets of fixing blocks are fixedly connected to both rotating rings, and fixing slot one and fixing slot two adapted to the fixing blocks are respectively opened on the first mounting frame and the second mounting frame.

[0010] Preferably, the fixing component includes a clamping ring 1 fixedly connected to the inner wall of the filter tube, a plurality of positioning blocks 1 fixedly connected to the clamping ring 1, a clamping ring 2 fixedly connected to the inside of the inlet tube on the right side of the clamping ring 1, a plurality of positioning blocks 2 fixedly connected to the clamping ring 2, and a plurality of limiting grooves 1 and 2 respectively adapted to the positioning blocks 1 and 2 on the blade frame.

[0011] Preferably, the connector includes a threaded rod rotatably installed inside the fixed tube. The right end of the threaded rod extends through the side wall of the fixed tube and is fixedly connected to a knob. The left end surface of the threaded rod is provided with a first driving component and a second driving component. The first driving component and the second driving component have the same structure. The first driving component is used to engage with the first mounting bracket, and the second driving component is used to engage with the second mounting bracket.

[0012] Preferably, the driving component includes a movable block threadedly connected to a threaded rod, a pair of limiting rods fixedly connected to one end of the movable block, a connecting rod rotatably mounted to the other end of the movable block, a sliding groove for sliding with the limiting rods on the inner wall of the fixed tube, a snap-fit ​​block rotatably connected to the connecting rod, and a snap-fit ​​groove for engaging the snap-fit ​​block on the first mounting bracket.

[0013] Preferably, the lower inner wall of the filter tube is provided with a through groove one and a through groove two, and a sedimentation box is fixedly connected inside both through groove one and through groove two.

[0014] Compared with the prior art, this utility model proposes a forged steel high-pressure ball valve, which has the following beneficial effects:

[0015] 1. This utility model is equipped with vortex blades. When fluid enters the valve body's inlet pipe from the left inlet of the filter tube, it first passes through a coarse filter screen, then a fine filter screen, and finally comes into contact with the vortex blades. Through the cooperation of the coarse and fine filter screens, impurities can be filtered in stages, reducing the filtration pressure of a single filter screen and thus improving the service life of the filter screen. At the same time, when the fluid passes through the vortex blades, a portion of the fluid impacts the blades, generating a tangential force that drives the vortex blades to rotate. The vortex blades then drive the fixed pipe to rotate, which in turn drives the first and second mounting brackets to rotate, thereby driving the coarse and fine filter screens to rotate. By rotating the coarse and fine filter screens, impurities are less likely to adhere to them. In addition, the centrifugal force generated during the rotation of the coarse and fine filter screens can cause the attached impurities to detach from the screen surface and eventually fall into the sedimentation box, further improving the service life of the filter screens.

[0016] 2. In this utility model, the filter tube is connected to the inlet pipe via a flange ring. By removing the bolts on the flange ring, the filter tube can be quickly disassembled as a whole, facilitating the replacement of the filter tube. By rotating the knob, the knob drives the threaded rod to rotate, which in turn drives the moving block on its surface to move. During the movement of the moving block, it drives the connecting rod, which in turn drives the locking block, thereby pulling the locking block out or pushing it into the groove. This achieves the locking and fixing or unfixing of the first mounting bracket and the second mounting bracket, making it convenient to disassemble the first mounting bracket and the second mounting bracket and replace the filter screen inside.

Detailed Implementation

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Reference Figure 1-6As shown, a forged steel high-pressure ball valve includes a valve body 1, a valve 2 at the upper end of the valve body 1, an inlet pipe 3 and an outlet pipe 4 fixedly connected to the left and right sides of the valve body 1 respectively, a filter pipe 5 on one side of the inlet pipe 3, a fixed pipe 8 inside the filter pipe 5, a blade holder 7 rotatably mounted on the right side of the fixed pipe 8, a vortex blade 6 rotatably connected to the fixed pipe 8 inside the blade holder 7, and a fixing component for fixing the blade holder 7 inside the filter pipe 5. A first, identically structured first... A mounting bracket 9 and a second mounting bracket 11 are provided. A fine filter screen 10 is fixedly installed on the first mounting bracket 9, and a coarse filter screen 12 is fixedly installed on the second mounting bracket 11. A connector for engaging the first mounting bracket 9 and the second mounting bracket 11 is provided inside the fixing tube 8. The inner wall of the filter tube 5 is provided with a first annular groove 501 and a second annular groove 502. A rotating ring 13 with the same structure is rotatably installed in both the first annular groove 501 and the second annular groove 502. The two rotating rings 13 are respectively engaged with the first mounting bracket 9 and the second mounting bracket 11. Fluid enters the valve body 1 through the left inlet of filter pipe 5 into inlet pipe 3. It first passes through coarse filter screen 12, then through fine filter screen 10, and finally comes into contact with vortex blades 6. Through the cooperation of coarse filter screen 12 and fine filter screen 10, impurities can be filtered in stages, reducing the filtration pressure of a single filter screen and thus improving the service life of the filter screen. At the same time, when the fluid passes through vortex blades 6, a portion of the fluid impacts vortex blades 6, generating a tangential force that drives vortex blades 6 to rotate. Vortex blades 6 then drive fixed pipe 8 to rotate, which in turn drives the first mounting bracket 9 and the second mounting bracket 11 to rotate, thereby driving coarse filter screen 12 and fine filter screen 10 to rotate. By rotating coarse filter screen 12 and fine filter screen 10, impurities are less likely to adhere to them. At the same time, the centrifugal force generated during the rotation of coarse filter screen 12 and fine filter screen 10 can cause attached impurities to detach from the screen surface and eventually fall into sedimentation box 19, further improving the service life of the filter screen.

[0027] Specifically, in this embodiment, a flange ring 16 is fixedly connected to the inlet pipe 3, and a flange ring 17 adapted to the flange ring 16 is fixedly connected to one end of the filter pipe 5. The flange ring 16 and flange ring 17 are fitted together and fixed by bolts. A flange ring 3 18 is fixedly connected to the left end of the filter pipe 5. By removing the bolts on the flange rings, the filter pipe 5 can be quickly disassembled as a whole, facilitating the replacement of the filter pipe 5 and reducing maintenance time.

[0028] Specifically, in this embodiment, several sets of fixing blocks 1301 are fixedly connected to both rotating rings 13. The first mounting frame 9 and the second mounting frame 11 are respectively provided with fixing groove 1 901 and fixing groove 2 1101 adapted to the fixing blocks 1301. Through the cooperation between the fixing blocks 1301 and fixing groove 1 901 and fixing groove 2 1101, when the first mounting frame 9 and the second mounting frame 11 rotate, they will drive the two fixing blocks 13 to rotate together, thereby reducing the friction between the first mounting frame 9 and the second mounting frame 11 and the filter tube 5 and improving the rotation effect.

[0029] Specifically, in this embodiment, the fixing component includes a clamping ring 14 fixedly connected to the inner wall of the filter tube 5. Several sets of positioning blocks 1401 are fixedly connected to the clamping ring 14. A clamping ring 25 fixedly connected to the inside of the inlet tube 3 is provided on the right side of the clamping ring 14. Several sets of positioning blocks 2501 are fixedly connected to the clamping ring 25. Several sets of limiting grooves 701 and 702, respectively adapted to the positioning blocks 1401 and 2501, are provided on the blade frame 7. By engaging the clamping ring 14 with one side of the blade frame 7, and then engaging the other end of the blade frame 7 with the clamping ring 25, the two clamping rings cooperate to limit the movement of the blade frame 7. When fluid passes through the vortex blade 6, a portion of the fluid impacts the blade, generating a tangential force that drives the vortex blade 6 to rotate. The vortex blade 6 then drives the fixed tube 8 to rotate.

[0030] Specifically, in this embodiment, the connector includes a threaded rod 801 rotatably installed inside the fixed tube 8. The right end of the threaded rod 801 extends through the side wall of the fixed tube 8 and is fixedly connected to a knob 802. The left end surface of the threaded rod 801 is provided with a driving component one and a driving component two. The structure of the driving component one and the driving component two is exactly the same. The driving component one is used to engage with the first mounting bracket 9, and the driving component two is used to engage with the second mounting bracket 11.

[0031] Specifically, in this embodiment, the driving component includes a movable block 803 threadedly connected to the threaded rod 801. One end of the movable block 803 is fixedly connected to a pair of limiting rods 804, and the other end of the movable block 803 is rotatably mounted with a connecting rod 805. The inner wall of the fixed tube 8 is provided with a sliding groove for sliding with the limiting rods 804. A snap-fit ​​block 806 is rotatably connected to the connecting rod 805, and the first mounting bracket 9 is provided with a slot for engaging the snap-fit ​​block 806. By rotating knob 802, knob 802 drives threaded rod 801 to rotate. The rotation of threaded rod 801 in turn drives driving component one and driving component two on its surface. Driving component one drives moving block 803 to move through the rotating threaded rod 801. During the movement of moving block 803, it drives connecting rod 802. Connecting rod 805 in turn drives locking block 806, thereby pulling out or pushing locking block 806 into the groove, thereby realizing the locking and fixing or unlocking of first mounting bracket 9 and second mounting bracket 11, so as to facilitate the disassembly of first mounting bracket 9 and second mounting bracket 11 and the replacement of their internal filters. The working process of driving component two is the same as that of driving component one, and will not be described again here.

[0032] Specifically, in this embodiment, the lower inner wall of the filter tube 5 is provided with a first through groove 503 and a second through groove 504, and a sedimentation box 19 is fixedly connected inside both the first through groove 503 and the second through groove 504.

[0033] The working principle of this utility model is as follows: During use, fluid enters the inlet pipe 3 of the valve body 1 from the left inlet of the filter pipe 5. It first passes through the coarse filter screen 12, then through the fine filter screen 10, and finally comes into contact with the vortex blades 6. Through the cooperation of the coarse filter screen 12 and the fine filter screen 10, impurities can be filtered in stages, reducing the filtration pressure of a single filter screen and thus improving the service life of the filter screen. At the same time, when the fluid passes through the vortex blades 6, a part of the fluid impacts the vortex blades 6, thereby generating a tangential force that drives the vortex blades 6 to rotate. The vortex blades 6 then drive the fixed pipe 8 to rotate, and the fixed pipe 8 then drives the first mounting bracket 9 and the second mounting bracket 11 to rotate, thereby driving the coarse filter screen 12 and the fine filter screen 10 to rotate. By rotating the coarse filter screen 12 and the fine filter screen 10, impurities are less likely to adhere to them. At the same time, the centrifugal force generated during the rotation of the coarse filter screen 12 and the fine filter screen 10 can cause the attached impurities to detach from the screen surface and eventually fall into the sedimentation box 19, further improving the service life of the filter screen.

[0034] After a period of use, the filter tube 5 can be quickly disassembled by removing the bolts on the flange ring, facilitating the overall replacement of the filter tube 5. Then, by rotating the knob 802, the knob 802 drives the threaded rod 801 to rotate. The rotation of the threaded rod 801 drives the driving component one and driving component two on its surface. The driving component one drives the moving block 803 to move through the rotating threaded rod 801. During the movement, the moving block 803 drives the connecting rod 802, and the connecting rod 805 drives the locking block 806, thereby pulling the locking block 806 out of the slot in the first mounting bracket 9 to accommodate the locking block 806, thus releasing the fixation to the first mounting bracket 9. The working process of the driving component two is the same as that of the driving component one, and will not be described in detail here. This achieves the release of the fixation of the first mounting bracket 9 and the second mounting bracket 11, making it convenient to disassemble the first mounting bracket 9 and the second mounting bracket 11, and then replace the coarse filter screen 12 and the fine filter screen 10 inside them.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
