Description

Technical Field

[0001] The utility model relates to the technical field of pipeline flanges, and specifically relates to a pipeline flange with a cut-off function. Background Technique

[0002] In some pipelines with relatively small flow rates and low pressures, pipeline flanges with cut-off functions are generally installed to reduce the production cost and make the installation and assembly simple and convenient.

[0003] The existing pipeline flanges with cut-off functions generally consist of structures such as a cut-off plate and a rotating rod. When in use, by rotating the rotating rod, the cut-off plate can be driven to rotate. And in order to prevent the cut-off plate from rotating on its own, a damping element is generally installed inside it to achieve the purpose of simplifying the pipeline and reducing the installation and assembly process.

[0004] However, in actual use, since the cut-off plate is generally fixedly connected to the rotating rod, when the cut-off valve inside it wears out, the entire flange generally needs to be replaced, which makes the use cost relatively high and the use economy relatively low. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pipeline flange with a cut-off function to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A pipeline flange with a cut-off function, including a flange body. A cut-off plate is arranged inside the flange body. A clamping groove is opened at the top inner part of the cut-off plate. A clamping block is clamped inside the clamping groove. A limiting groove is opened at the middle bottom part of the cut-off plate. Sliding grooves are opened at the front and rear sides of the bottom of the cut-off plate. Rotating rods are rotatably connected to the upper and lower sides inside the flange body.

[0007] Preferably, an installation groove is opened at the lower side inside the upper rotating rod. A pull rope is slidably connected inside the installation groove. An elastic member I is sleeved outside the pull rope. The bottom end of the pull rope is fixedly connected to an installation block. The bottom end of the installation block is fixedly connected to the top end of the clamping block.

[0008] Preferably, a plurality of grooves are opened inside the limiting groove. A placement groove is opened inside the lower rotating rod. An elastic member II is fixedly connected to the lower side inner wall of the placement groove. The top end of the elastic member II is fixedly connected to a placement block. A limiting block is rotatably connected to the top end of the placement block. The outside of the limiting block is engaged with the inside of the limiting groove. A plurality of convex blocks are fixedly connected to the outside of the limiting block.

[0009] Preferably, the clamping block is designed in a cross shape and is adapted to the clamping groove.

[0010] Preferably, a pull ring is provided inside the top end of the upper rotating rod. A buckling groove is slidably connected inside the pull ring, and the bottom end of the buckling groove is fixedly connected to the top end of a pull rope.

[0011] Preferably, the mounting block is slidably connected inside the mounting groove. One end of the first elastic member is fixedly connected to the inner wall of the mounting groove, and the other end of the first elastic member is fixedly connected to the top end of the mounting block.

[0012] Preferably, the placing block is slidably connected inside the placing groove, the convex block is slidably connected inside the limiting groove, the convex block fits inside the corresponding groove, and the limiting block slides in the sliding groove.

[0013] Compared with the prior art, the beneficial effects of a pipeline flange with a cut-off function proposed by the present utility model are as follows: By modularly designing the rotating rod and the cut-off plate, the rotating rod and the cut-off plate can be conveniently disassembled and installed, so that the cut-off plate can be replaced separately, and thus it is not necessary to replace the entire flange, thereby reducing the usage cost and making the usage economy relatively high.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to clearly and completely describe the purpose and technical solutions of the present utility model, and make its advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Embodiment 1: Please refer to Figures 1 - 5 , the present utility model provides a technical solution: a pipeline flange with a cut-off function, including a flange body 1. An end plate 2 is arranged inside the flange body 1. A clamping groove 3 is opened at the top inner part of the end plate 2. A clamping block 10 is clamped inside the clamping groove 3. The clamping block 10 is designed in a cross shape and is adapted to the clamping groove 3, so that the clamping block 10 can drive the end plate 2 to rotate. A limiting groove 4 is opened at the middle part of the bottom end of the end plate 2. Slide grooves 19 are opened on both the front and rear sides of the bottom end of the end plate 2. Both the upper and lower sides inside the flange body 1 are rotatably connected with a rotating rod 5. The flange body 1 plays a limiting role on the rotating rod 5, enabling the rotating rod 5 to rotate smoothly. The upper rotating rod 5 is used to drive the end plate 2 to rotate, and the lower rotating rod 5 is used to support the end plate 2. The clamping block 10 is slidably connected inside the upper rotating rod 5, so that the rotating rod 5 can drive the clamping block 10 to rotate.

[0022] When the end plate 2 needs to be replaced, by pulling up the clamping block 10, the clamping block 10 can be disengaged from the inside of the clamping groove 3, and then the end plate 2 is moved left or right, so that the end plate 2 can be conveniently disassembled. On the contrary, by sliding the end plate 2 into the inside of the flange body 1, the clamping block 10 is moved downward, and then the clamping block 10 can be engaged with the inside of the clamping groove 3, so that the rotating rod 5 can drive the end plate 2 to rotate.

[0023] Embodiment 2: On the basis of Embodiment 1, in order to facilitate pulling the clamping block 10, an installation groove 6 is opened on the lower side inside the upper rotating rod 5. A pull rope 7 is slidably connected inside the installation groove 6. The installation groove 6 plays a limiting role on the pull rope 7, so that the pull rope 7 will not deviate when sliding. An elastic member 8 is sleeved outside the pull rope 7. The bottom end of the pull rope 7 is fixedly connected to an installation block 9. The pull rope 7 is used to pull the installation block 9 to move. The installation block 9 is slidably connected inside the installation groove 6. The installation groove 6 plays a limiting role on the installation block 9, so that the installation block 9 will not deviate when moving. One end of the elastic member 8 is fixedly connected to the inner wall of the installation groove 6, and the other end of the elastic member 8 is fixedly connected to the top end of the installation block 9. The bottom end of the installation block 9 is fixedly connected to the top end of the clamping block 10. A pull ring 11 is opened inside the top end of the upper rotating rod 5. The two sides of the pull ring 11 are inclined grooves, which enables the fingers to conveniently penetrate into the pull ring 11, so as to conveniently pull the buckling groove 12. A buckling groove 12 is slidably connected inside the pull ring 11. The pull ring 11 plays a limiting role on the buckling groove 12, so that the buckling groove 12 will not deviate when moving. The bottom end of the buckling groove 12 is fixedly connected to the top end of the pull rope 7. The buckling groove 12 is used to pull the pull rope 7 to move upward.

[0024] When it is necessary to pull the clamping block 10, by pulling the buckling groove 12 upward, the buckling groove 12 can conveniently pull the pull rope 7 to move upward, and then the pull rope 7 can pull the installation block 9 to move upward, so that the installation block 9 can squeeze the elastic member 8 to deform, and the installation block 9 can pull the clamping block 10 out of the clamping groove 3. On the contrary, by releasing the buckling groove 12, the elastic member 8 can perform a reset movement, and then the elastic member 8 can push the installation block 9 to move downward, so that the installation block 9 can push the clamping block 10 to move downward, and then the clamping block 10 can be engaged with the clamping groove 3.

[0025] Embodiment 3: On the basis of Embodiment 2, in order to make the rotation of the cut-off plate 2 more stable, a plurality of grooves 18 are formed inside the limiting groove 4, and a placement groove 13 is formed inside the lower rotating rod 5. A second elastic member 14 is fixedly connected to the lower side of the inner wall of the placement groove 13. The top end of the second elastic member 14 is fixedly connected to a placement block 15. The placement block 15 is slidably connected inside the placement groove 13. The placement groove 13 limits the placement block 15 inside, so that the placement block 15 will not shift when sliding. The top end of the placement block 15 is rotatably connected to a limiting block 16. The outside of the limiting block 16 is engaged with the inside of the limiting groove 4, so that the connection between the cut-off plate 2 and the limiting block 16 is relatively stable. A plurality of convex blocks 17 are fixedly connected to the outside of the limiting block 16. The convex blocks 17 are slidably connected inside the limiting groove 4. The limiting groove 4 squeezes the convex blocks 17 to deform. The convex blocks 17 are fitted with the inside of the corresponding grooves 18, so that the connection between the limiting block 16 and the limiting groove 4 is more stable. The limiting block 16 slides with the sliding groove 19, so that the sliding groove 19 can push the limiting block 16 to move downward.

[0026] When the cut-off plate 2 needs to be disassembled, by pulling the cut-off plate 2 outward, the limiting groove 4 slides on the arc surface of the limiting block 16, and then the limiting block 16 can be pushed to move downward, so that the limiting block 16 can be disengaged from the inside of the limiting groove 4, and then the cut-off plate 2 can be conveniently disassembled. On the contrary, by sliding the cut-off plate 2 into the flange body 1 and making the sliding groove 19 squeeze the limiting block 16 to move downward, the limiting block 16 can push the placement block 15 to move downward, and then the placement block 15 can squeeze the second elastic member 14 to deform. Thus, after the limiting block 16 and the limiting groove 4 are at the same horizontal position, the second elastic member 14 can perform a reset movement, and then the second elastic member 14 can push the placement block 15 to move upward, so that the placement block 15 can push the limiting block 16 to be engaged with the inside of the limiting groove 4, and then the convex blocks 17 can be fitted with the inside of the grooves 18, so that the limiting block 16 can be more stably clamped with the limiting groove 4, and then the cut-off plate 2 can be more stably installed.

[0027] During actual use, by pulling the buckling groove 12 upward, the buckling groove 12 can conveniently pull the drawstring 7 to move upward, so that the drawstring 7 can pull the mounting block 9 to move upward, causing the mounting block 9 to squeeze the first elastic member 8 to deform, and enabling the mounting block 9 to pull the latch 10 out of the clamping groove 3. Then, the stop plate 2 is moved left or right, so that the limiting groove 4 can slide on the arc surface of the limiting block 16, and then the limiting block 16 is pushed downward, so that the limiting block 16 can be disengaged from the inside of the limiting groove 4, and thus the stop plate 2 can be conveniently disassembled. On the contrary, by sliding the stop plate 2 into the flange body 1 and making the sliding groove 19 squeeze the limiting block 16 to move downward, the limiting block 16 can push the placement block 15 to move downward, so that the placement block 15 squeezes the second elastic member 14 to deform. When the limiting block 16 and the limiting groove 4 are at the same horizontal position, the second elastic member 14 can perform a reset movement, and then the second elastic member 14 can push the placement block 15 to move upward, so that the placement block 15 can push the limiting block 16 to engage with the inside of the limiting groove 4, and thus the convex block 17 can be fitted with the inside of the concave groove 18, making the engagement between the limiting block 16 and the limiting groove 4 more stable. Then, by releasing the buckling groove 12, the first elastic member 8 can perform a reset movement, and then the first elastic member 8 can push the mounting block 9 to move downward, so that the mounting block 9 can push the latch 10 to move downward, and then the latch 10 can engage with the clamping groove 3, making the installation of the stop plate 2 more stable.
