Description

Technical Field

[0001] The utility model relates to the technical field of pipeline flow regulating flanges, in particular to a pipeline flow regulating flange. Background Art

[0002] Flange pipe is a pipe connection device, which is mainly composed of flange, flange gasket, flange bolts and other components. Flange and flange bolts are responsible for connecting and fixing the pipe, while flange gasket plays the role of sealing the pipe.

[0003] Flange pipes in the prior art are usually equipped with valves inside to regulate the flow inside the pipeline. When the valve is in use, it is usually necessary to assemble a sealing gasket on the outside. However, the sealing gasket will generate friction when rotating between the valve body and the pipeline to regulate the flow for a long time, which will reduce the service life of the sealing gasket. Over time, it will lead to the risk of loose pipeline sealing and internal fluid leakage. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a pipeline flow regulating flange to solve the technical problem that friction is generated between the above-mentioned valve body and the pipeline when the flow is rotated to adjust the flow, which in turn leads to a reduced service life of the sealing gasket, and over time may cause the pipeline to be loosely sealed and internal fluid leakage and other risks.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a pipeline flow regulating flange, comprising: a flange pipeline, a valve ball, a sealing sleeve and a valve stem group, the valve ball is assembled inside the flange pipeline, the sealing sleeve is assembled on both ends of the outside of the valve ball, the valve stem group is assembled on the top of the valve ball, and the interior of the valve stem group is equipped with a control mechanism, the control mechanism includes a vertical arm, hinges are evenly distributed at both ends of the outside of the vertical arm, a connecting rod is connected to the outside of the hinge, and the other end of the connecting rod is connected to a push rod through a hinge, the outside of the push rod is connected to a push plate, and the push plate is connected to the sealing sleeve, the bottom of the vertical arm is connected to a spring, and the spring is connected to the inner bottom of the valve stem group.

[0006] Preferably, both ends of the interior of the valve ball are provided with square grooves, and the square grooves are connected to the valve stem assembly, and the square grooves can be used to assemble the valve stem assembly.

[0007] Preferably, a guide block is assembled on the top of the push rod, and the guide block is slidably connected to the square groove. The guide block cooperates with the square groove to guide the push rod, thereby causing it to move linearly.

[0008] Preferably, the valve stem group includes a hollow column, and a torsion wheel is installed on the top of the hollow column. Vertical grooves are evenly distributed on the outside of the hollow column. The hollow column can support the vertical arm to move up and down. The torsion wheel makes it convenient for the staff to drive the valve stem group to rotate, and the vertical groove facilitates the transmission of the connecting rod.

[0009] Preferably, both ends of the exterior of the valve ball are provided with assembly grooves, and the assembly grooves are connected to the sealing sleeve. The assembly grooves can accommodate the sealing sleeve and guide the sealing sleeve.

[0010] Preferably, there are twelve groups of push rods and push plates, which are evenly distributed at both ends of the exterior of the vertical arm. Multiple groups of push rods and push plates improve the stability of the control mechanism when driving the sealing sleeve.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The pipeline flow regulating flange automatically eliminates the friction between the sealing sleeve and the flange pipeline through the added control mechanism when the fluid inside the pipeline is regulated, thereby avoiding the sealing sleeve from continuously rubbing against the flange pipeline during fluid regulation, thereby improving the overall sealing and flow control performance of the device. At the same time, after the fluid is regulated, the control mechanism returns to its position and automatically improves the fit between the sealing sleeve and the flange pipeline, thereby avoiding the valve ball from being accidentally driven, which may cause fluid regulation failure.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A pipeline flow regulating flange comprises: a flange pipeline 1, a valve ball 2, a sealing sleeve 3 and a valve stem group 4, the valve ball 2 is assembled inside the flange pipeline 1, the sealing sleeve 3 is assembled at both ends of the outside of the valve ball 2, the valve stem group 4 is assembled on the top of the valve ball 2, and the valve stem group 4 is connected to the valve ball 2, and the valve stem group 4 is assembled inside the valve stem group 4. The control mechanism 5 comprises a vertical arm 51, hinges are evenly distributed at both ends of the outside of the vertical arm 51, a connecting rod 52 is connected to the outside of the hinge, and the other end of the connecting rod 52 is connected to a push rod 54 through a hinge, the outside of the push rod 54 is connected to a push plate 55, and the push plate 55 is connected to the sealing sleeve 3, the bottom of the vertical arm 51 is connected to a spring 53, and the spring 53 is connected to the inner bottom of the valve stem group 4.

[0020] The flange pipe 1 is a common flange pipe in the prior art. The cooperation of the valve ball 2, the sealing sleeve 3 and the valve stem group 4 can make the flange pipe 1 form a simple valve body, which can then adjust and control the flow. The valve stem group 4 can control the rotation of the valve ball 2, and the sealing sleeve 3 can increase the sealing between the valve ball 2 and the flange pipe 1.

[0021] The vertical arm 51 can move up and down inside the valve stem group 4, and the connecting rod 52 can drive the spring 53 to move through the vertical arm 51 that moves up and down. The spring 53 can pull the sealing sleeve 3 to move through the push plate 55, and the spring 53 can return to its original position when the vertical arm 51 is no longer pressed.

[0022] See also Figure 3 and Figure 4 Square grooves 21 are provided at both ends of the interior of the valve ball 2, and the square grooves 21 are connected to the valve stem group 4. The square grooves 21 can assemble the valve stem group 4. A guide block 56 is assembled on the top of the push rod 54, and the guide block 56 is slidably connected to the square grooves 21. The guide block 56 cooperates with the square grooves 21 to guide the push rod 54, thereby causing it to move linearly.

[0023] The valve stem group 4 includes a hollow column, and a torsion wheel is installed on the top of the hollow column. Vertical grooves are evenly distributed on the outside of the hollow column. The hollow column can support the vertical arm 51 to move up and down. The torsion wheel makes it convenient for the staff to drive the valve stem group 4 to rotate, and the vertical groove facilitates the transmission of the connecting rod 52.

[0024] Both ends of the outside of the valve ball 2 are provided with assembly grooves 22, and the assembly grooves 22 are connected to the sealing sleeve 3. The assembly grooves 22 can accommodate the sealing sleeve 3 and guide the sealing sleeve 3. There are twelve groups of push rods 54 and push plates 55, and they are evenly distributed at both ends of the outside of the vertical arm 51. Multiple groups of push rods 54 and push plates 55 improve the stability of the control mechanism 5 when driving the sealing sleeve 3.

[0025] In this solution, the flange pipe 1 is first connected to the pipeline. When the flow inside the pipeline needs to be adjusted, the vertical arm 51 is pressed down, and the push rod 54 is pulled to move by the connecting rod 52, and then the sealing sleeve 3 is driven to move by the push plate 55, thereby releasing the friction between the sealing sleeve 3 and the inner wall of the flange pipe 1, and then the valve ball 2 is driven to rotate by rotating the valve stem group 4 to complete the flow adjustment. After the flow adjustment is completed, the pressure on the vertical arm 51 is released. At this time, the vertical arm 51 is returned to its original position by the spring 53, and then the sealing sleeve 3 is driven to fit tightly against the inner wall of the flange pipe 1, forming a seal between the valve ball 2, the sealing sleeve 3 and the flange pipe 1. At the same time, the spring 53 is used to increase the fit between the sealing sleeve 3 and the flange pipe 1, thereby preventing the valve ball 2 from being accidentally driven, which may cause fluid regulation failure.

[0026] When the fluid inside the pipeline is adjusted, the friction between the sealing sleeve 3 and the flange pipeline 1 is automatically eliminated through the added control mechanism 5, thereby avoiding the sealing sleeve 3 from continuously rubbing against the flange pipeline 1 during fluid adjustment, which may cause the service life of the sealing sleeve 3 to be reduced. At the same time, after the fluid adjustment is completed, the control mechanism 5 returns to its position and automatically improves the fit between the sealing sleeve 3 and the flange pipeline 1, thereby avoiding the valve ball 2 from being accidentally driven, which may cause the fluid adjustment to fail.
