Description

Technical Field

[0001] The utility model relates to a globe valve, in particular to a globe valve which is convenient to install. Background Art

[0002] A globe valve is a control element widely used in pipeline systems, mainly used to cut off, connect or regulate the flow of media (such as water, steam, gas, oil products, etc.) in pipelines. Its working principle is: the globe valve usually drives the valve flap to move axially along the valve seat by rotating the valve stem. When the valve flap rises, the valve opens and allows the medium to pass through; when the valve flap descends, the valve closes to prevent the medium from flowing.

[0003] Currently, when installing a globe valve, it is usually connected to the pipeline by bolts. If it is only a temporary connection, it is necessary to screw in and out a number of bolts each time, which is cumbersome to operate and has low work efficiency. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a globe valve that can be easily installed with a pipeline.

[0005] To achieve the above purpose, the utility model provides the following technical solution: it includes a valve body and a pipeline. The valve body has an installation part opposite to the pipeline. A plurality of fixing holes are provided on the pipeline, and fixing rods opposite to the fixing holes are provided on the installation part. The fixing rods have fixing parts located in the fixing holes. Limit blocks are provided on the fixing parts. Limit inlet grooves for the limit blocks to enter are provided on the inner wall of the fixing holes. A limit ring groove perpendicular to the moving direction of the limit block is provided on the inner wall of the fixing hole and the limit ring groove extends to communicate with the limit inlet groove. The limit block enters the limit inlet groove to form the fixation of the pipeline and the installation part.

[0006] By adopting the above technical solution, when it is necessary to fix the valve body and the pipeline, align the fixing rods on the valve body with the fixing holes on the pipeline and insert them, and the limit blocks are opposite to the limit inlet grooves until the limit blocks move to the intersection of the limit inlet groove and the limit ring groove. Then rotate the fixing rod, thereby driving the limit block to move along the limit ring groove. At this time, the fixing rod cannot move along the fixing hole, that is, the valve body and the pipeline are fixed. Compared with fixing by bolts, this solution is simpler to install, suitable for temporary connection, and effectively improves the installation efficiency.

[0007] The present utility model is further configured as follows: The fixing part includes a fixing block, a moving block, a moving spring, a moving shaft and a linkage block. The starting end of the limiting ring groove is connected to the end of the limiting inlet groove. The linkage block is fixed to the fixing rod. On the other side of the linkage block relative to the fixing rod, there is a moving groove for the moving shaft to slide. The moving shaft has a moving end located in the moving groove. The other end of the moving shaft relative to the moving end is fixedly arranged on the fixing block. The moving block is slidably arranged on the moving shaft. The moving spring is arranged between the moving block and the fixing block and drives the moving block to move away from the fixing block. Limiting blocks are respectively arranged on the moving block and the fixing block.

[0008] By adopting the above technical solution, when the limiting block of the fixing block moves to the end of the limiting inlet groove, at this time, the limiting block of the fixing block is opposite to the limiting ring groove. As the fixing rod continues to enter, the fixing block does not move, the moving spring is compressed, the moving block approaches the fixing block until the limiting block on the moving block is also opposite to the limiting ring groove. Then rotate the fixing rod so that the two limiting blocks move synchronously along the limiting ring groove. At this time, the moving spring drives the moving block to move away from the fixing block, so that the moving block abuts against the limiting ring groove to prevent the fixing rod from rotating randomly.

[0009] The present utility model is further configured as follows: The moving groove includes a moving cavity and a communication channel connecting the moving cavity to the outside. The moving end is located in the moving cavity and the moving end cannot pass through the communication channel. The moving end and the moving cavity are square to form synchronous rotation of the moving shaft and the fixing rod.

[0010] By adopting the above technical solution, it prevents the moving shaft from disengaging from the moving groove, and at the same time ensures that the fixing rod can drive the moving shaft to rotate when rotating, and finally enables the two limiting blocks to rotate accordingly.

[0011] The present utility model is further configured as follows: On the other side of the fixing rod relative to the fixing part, there is an operating block.

[0012] The present utility model is further configured as follows: It includes a valve stem, a valve flap and a valve seat. There is a flow channel for the medium to flow through in the valve body. The valve stem moves in a direction perpendicular to the flow channel. The valve flap is arranged on the valve stem and is in sealing cooperation with the valve seat to cut off the flow channel. There is a flow port opposite to the medium on the pipeline.

[0013] The present utility model is further configured as follows: A sealing ring is arranged between the pipeline and the installation part.

[0014] By adopting the above technical solution, the setting of the sealing ring prevents leakage, which is convenient and effective. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] Such as Figures 1-5As shown in the figure, the utility model discloses a globe valve convenient for installation, which comprises a valve body 1 and a pipeline 2. The valve body 1 has an installation part 11 opposite to the pipeline 2. A plurality of fixing holes 21 are arranged on the pipeline 2, and fixing rods 3 opposite to the fixing holes 21 are arranged on the installation part 11. The fixing rods 3 have fixing parts 31 located in the fixing holes 21. Limit blocks 30 are arranged on the fixing parts 31. A limit inlet groove 22 for the limit blocks 30 to enter is arranged on the inner wall of the fixing hole 21. A limit ring groove 23 perpendicular to the moving direction of the limit block 30 is arranged on the inner wall of the fixing hole 21, and the limit ring groove 23 extends to communicate with the limit inlet groove 22. The limit block 30 enters the limit inlet groove 22 to fix the pipeline 2 and the installation part 11. When it is necessary to fix the valve body 1 and the pipeline 2, the fixing rod 3 on the valve body 1 is aligned with the fixing hole 21 on the pipeline 2 and inserted, and the limit block 30 is opposite to the limit inlet groove 22 until the limit block 30 moves to the intersection of the limit inlet groove 22 and the limit ring groove 23. Then the fixing rod 3 is rotated, so as to drive the limit block 30 to move along the limit ring groove 23. At this time, the fixing rod 3 cannot move along the fixing hole 21, that is, the valve body 1 and the pipeline 2 are fixed. Compared with the use of bolts for fixing, this solution is simpler to install, suitable for temporary connection, and effectively improves the installation efficiency.

[0024] The fixing part 31 includes a fixing block 32, a moving block 33, a moving spring 34, a moving shaft 35 and a linkage block 36. The starting end of the limit ring groove 23 is connected to the end of the limit inlet groove 22. The linkage block 36 is fixed to the fixing rod 3. A moving groove 37 for the moving shaft 35 to slide is arranged on the other side of the linkage block 36 relative to the fixing rod 3. The moving shaft 35 has a moving end 351 located in the moving groove 37. The other end of the moving shaft 35 relative to the moving end 351 is fixedly arranged on the fixing block 32. The moving block 33 is slidably arranged on the moving shaft 35. The moving spring 34 is arranged between the moving block 33 and the fixing block 32 and drives the moving block 33 to move away from the fixing block 32. The limit blocks 30 are respectively arranged on the moving block 33 and the fixing block 32. When the limit block 30 of the fixing block 32 moves to the end of the limit inlet groove 22, at this time, the limit block 30 of the fixing block 32 is opposite to the limit ring groove 23. As the fixing rod 3 continues to enter, the fixing block 32 does not move, the moving spring 34 is compressed, and the moving block 33 moves closer to the fixing block 32 until the limit block 30 on the moving block 33 is also opposite to the limit ring groove 23. Then the fixing rod 3 is rotated, so that the two limit blocks 30 move synchronously along the limit ring groove 23. At this time, the moving spring 34 drives the moving block 33 to move away from the fixing block 32, so that the moving block 33 abuts against the limit ring groove 23 to prevent the fixing rod 3 from rotating randomly.

[0025] The moving groove 37 includes a moving cavity 38 and a communication channel 39 that communicates the moving cavity 38 with the outside. The moving end 351 is located in the moving cavity 38 and cannot pass through the communication channel 39. The moving end 351 and the moving cavity 38 are square and form the synchronous rotation of the moving shaft 35 and the fixed rod 3, preventing the moving shaft 35 from disengaging from the moving groove 37. At the same time, it ensures that the fixed rod 3 can drive the moving shaft 35 to rotate when rotating, and finally enables the two limit blocks 30 to rotate accordingly.

[0026] On the other side of the fixed rod 3 relative to the fixed part 31, there is an operation block 301

[0027] It includes a valve stem 4, a valve flap 5 and a valve seat 6. A flow channel 7 for the medium to flow through is provided in the valve body 1. The valve stem 4 moves in a direction perpendicular to the flow channel 7. The valve flap 5 is arranged on the valve stem 4 and is in sealing cooperation with the valve seat 6 to form the cutoff of the flow channel 7. A communication port 24 opposite to the medium is provided on the pipeline 2.

[0028] A sealing ring is provided between the pipeline 2 and the installation part 11. The setting of the sealing ring prevents leakage.

[0029] The sealing ring is not shown in the figure.

[0030] Specific embodiment: When it is necessary to fix the valve body 1 and the pipeline 2, align the fixed rod 3 on the valve body 1 with the fixing hole 21 on the pipeline 2 and insert it, and the limit block 30 is opposite to the limit inlet groove 22. When the limit block 30 of the fixing block 32 moves to the end of the limit inlet groove 22, at this time, the limit block 30 of the fixing block 32 is opposite to the limit ring groove 23. As the fixed rod 3 continues to enter, the fixing block 32 does not move, the moving spring 34 is compressed, and the moving block 33 moves closer to the fixing block 32 until the limit block 30 on the moving block 33 is also opposite to the limit ring groove 23. Then rotate the fixed rod 3 so that the two limit blocks 30 move synchronously along the limit ring groove 23. At this time, the moving spring 34 drives the moving block 33 to move away from the fixing block 32, so that the moving block 33 abuts against the limit ring groove 23, preventing the random rotation of the fixed rod 3. At this time, the fixed rod 3 cannot move along the fixing hole 21, that is, the valve body 1 and the pipeline 2 are fixed.

[0031] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention.
