Description

Technical Field

[0002] In many industrial fields, fluid transportation is a vital link. As a key component in the pipeline system, elbows are used to change the flow direction of fluids. However, in practical applications, elbows face a series of problems and challenges.

[0003] Traditional elbows often become clogged during long-term use. This may be because impurities and particles carried in the fluid gradually accumulate inside the elbow, resulting in a reduction in the flow area and affecting the normal delivery of the fluid. Blockage will not only reduce the working efficiency of the system, but may also cause a series of failures and downtime, increasing maintenance costs and production losses.

The slider 47 fits with the slide groove 401, and the slider 47 slides in the slide groove 401.

[0031] Reference Figure 1 - Figure 3 The anti-blocking component also includes a positioning block 44, which is used to connect the plug block 45 and the sleeve 41 to ensure that when the plug block 45 is limited, the sleeve 41 will also be limited. The inner wall of the positioning block 44 is elastically connected to the plug block 45 through a compression spring 46. A slot 402 is provided on the right surface of the flange 32, and the left end of the plug block 45 fits in the slot 402.

When aligned, the impurities blocked by the filter plate 43 can be discharged, and the inner wall of the rubber pad 42 fits with the outer wall of the wear-resistant elbow body 1.

[0034] Reference Figure 1 - Figure 3 The outer wall of the filter plate 43 fits with the inner wall of the wear-resistant elbow body 1, and the gap between the two is extremely small, so impurities cannot pass through. A mesh hole is opened on the left surface of the filter plate 43, and the mesh hole is through-shaped, so that the fluid can pass through and impurities will be blocked. The filter plate 43 is located on the right side of the through groove 1. The impurities blocked by the filter plate 43 will stay on the left side of the filter plate 43 and in the through groove 1. The slider 47 is set to be T-shaped, and the slider 47 is slidably connected to the inner wall of the slide groove 401. The slide groove 401 is set to be annular. When the slider 47 slides along the slide groove 401, the sleeve 41 will rotate.

[0035] Reference Figure 1 - Figure 3 The plug block 45 is set to be L-shaped, and the plug block 45 passes through and is slidably connected to the upper surface of the positioning block 44. The upper surface of the plug block 45 protrudes from the upper surface of the positioning block 44 and can be toggled. The plug block 45 slides horizontally, and the left surface of the plug block 45 passes through the left surface of the positioning block 44. One end of the compression spring 46 is fixedly connected to the inner wall of the right side of the positioning block 44, and the other end of the compression spring 46 is fixedly connected to the right surface of the plug block 45. When the plug block 45 moves to the right, the compression spring 46 will be squeezed to generate a reaction force. The plug block 45 is plugged into the inner wall of the slot 402, which can limit the sleeve 41 and the rubber pad 42. When the plug block 45 is plugged into the slot 402 located above, the through slots 1, 2, and 3 will not be aligned. When the plug block 45 is plugged into the slot 402 located below, the through slots 1, 2, and 3 will be aligned, and impurities can be discharged from the pipeline 2 and the wear-resistant elbow body 1.

[0036] Reference Figure 1 - Figure 3 The right surface of the card block 35 is fixedly connected to the left surface of the flange 2 32, and the card block 35 is inserted into the inner wall of the slot 301. When the card block 35 is inserted into the slot 301, the right surface of the limit block 34 will be squeezed. The limit block 34 is inserted into the inner wall of the limit groove 302, and the flange 1 31 and the flange 2 32 can be initially fixed. The right surface of the limit block 34 is opened as an inclined surface, and the left surface of the limit block 34 is opened as an inclined surface. By squeezing the inclined surface of the limit block 34, the limit block 34 will move upward. When the card block 35 and the slot 301 are inserted, the limit block 34 will be aligned with the limit groove 302, and the bottom end of the limit block 34 in the initial position is located in the slot 301.

[0037] Reference Figure 1 - Figure 3 The limit block 34 is slidably connected to the inner wall of the flange 1 31 and slides longitudinally. One end of the limit spring 33 is fixedly connected to the inner wall at the top of the flange 1 31, and the other end of the limit spring 33 is fixedly connected to the upper surface of the limit block 34. When the limit block 34 moves upward, it will squeeze the limit spring 33 to generate a reaction force.

[0038] Working principle: When the wear-resistant elbow body 1 needs to be installed, the flange 2 32 on the wear-resistant elbow body 1 is docked with the flange 1 31 on the pipe 2. At this time, the block 35 is inserted into the slot 301. The block 35 will squeeze the right inclined surface of the limit block 34 during the insertion process, so that the limit block 34 moves upward to contact the block and compress the limit spring 33. When the block 35 is fully inserted into the slot 301, the limit block 34 is aligned with the limit slot 302 under the reaction force of the limit spring 33 and inserted into it, thereby achieving the preliminary fixation of the flange 1 31 and the flange 2 32. Then, the flange 1 31 and the flange 2 32 are fixed together by tightening the bolts, and the installation of the wear-resistant elbow body 1 is completed, and the sealing can be ensured.

[0039] When the fluid flows through the wear-resistant elbow body 1, due to the setting of the filter plate 43, the impurities in the fluid will be blocked by the filter plate 43. When it is necessary to clean the blocked impurities, move the plug block 45 to make it disengage from the current slot 402, and then slide the slider 47 along the slide groove 401 to drive the sleeve 41 to rotate. When the plug block 45 rotates to another slot 402 position, release the plug block 45, and insert the plug block 45 into the slot 402 under the action of the compression spring 46 to achieve positioning. When the plug block 45 is plugged into the slot 402 located below, the through slots 1, 2 and 3 are aligned at this time, and the impurities blocked by the filter plate 43 can be discharged through these through slots, so that the impurities can be cleaned without disassembly, effectively preventing blockage. At the same time, the rubber pad 42 can ensure the seal between the sleeve 41 and the wear-resistant elbow body 1 to prevent fluid leakage. The filter plate 43 fits tightly with the inner wall of the wear-resistant elbow body 1 to ensure that only fluid passes through and impurities are effectively blocked. After the impurities are cleaned, the plug block 45 is moved in the same way to contact the limit and the sleeve 41 is rotated to the initial position, and then the plug block 45 is loosened to make it engage with the slot 402 located above to form a limit. At this time, the through grooves 1, 2 and 3 will not be aligned, which can prevent fluid from leaking and ensure the normal circulation of the fluid.
