Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a valve with a movable flange. Background Art

[0002] Currently, flanged valves are installed with pipe flanges. The pipe flanges are welded to the pipes, and the valve flanges are cast integrally with the valve body. The valve is installed between the two pipes. After welding the two pipe flanges, the axes of the two pipe flange mounting holes are misaligned, causing the valve body flange to misalign with the pipe flange mounting holes, making valve body installation difficult. When the pipeline is buried, rework and rectification are costly and difficult.

[0003] Therefore, it is urgent to design a valve with a movable flange to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a valve with a movable flange, which has the advantage that the flange can be freely rotated for easy installation, and solves the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical solution of a valve with a movable flange of the present invention is as follows:

[0006] A valve with a movable flange includes multiple flange blocks and a valve body. The multiple flange blocks can be assembled into a flange disc. Fixing holes are provided on the multiple flange blocks. After the multiple flange blocks are assembled into the flange disc, the fixing holes on adjacent flange blocks overlap. Adjacent flange blocks are connected and fixed by fasteners passing through the fixing holes. The flange disc can be sleeved onto the valve body and can be rotated relative to the valve body to be installed with the flange to be docked.

[0007] Furthermore, an annular groove is provided on the valve body, and the flange is sleeved onto the annular groove of the valve body to limit the radial and axial positions of the flange.

[0008] Furthermore, multiple flange blocks are provided with abutment grooves. After the multiple flange blocks are assembled into a flange plate, the multiple abutment grooves are connected to form an annular step groove. When the flange plate is sleeved onto the annular groove of the valve body, the annular step groove covers the side wall outside the annular groove of the valve body.

[0009] Furthermore, a plurality of flange blocks are assembled on the annular groove of the valve body to form a flange plate.

[0010] Furthermore, a first step groove and a second step groove are respectively provided at both ends of the flange block. After multiple flange blocks are assembled into a flange plate, the first step groove of the flange block is buckled with the second step groove of its adjacent flange block, and the second step groove of the flange block is buckled with the first step groove of its adjacent flange block.

[0011] Furthermore, the first step groove is provided on the first surface of the flange block, and the second step groove is provided on the second surface of the flange block.

[0012] Furthermore, fixing holes are provided on the first step groove and the second step groove. When the first step groove of the flange block is buckled with the second step groove of its adjacent flange block, and the second step groove of the flange block is buckled with the first step groove of its adjacent flange block, the fixing hole of the first step groove coincides with the fixing hole of the second step groove.

[0013] Furthermore, the fastener is a bolt. After the fixing hole of the first step groove overlaps with the fixing hole of the second step groove, the bolt is passed through the fixing hole to fix the adjacent flange blocks.

[0014] Furthermore, mounting holes are provided on the first step groove and the second step groove. When the first step groove of the flange block is engaged with the second step groove of its adjacent flange block, and the second step groove of the flange block is engaged with the first step groove of its adjacent flange block, the mounting hole of the first step groove coincides with the mounting hole of the second step groove.

[0015] Furthermore, one end of the valve body away from the annular groove is fixedly connected to a fixed flange.

[0016] The utility model has the following advantages: the flange is separated from the valve body, and the flange part is installed on the valve body as a separate component for use, and the flange part can be rotated freely, so that the valve is installed on the pipeline during the construction process, and even if the flange welded on the pipeline is misaligned and not concentric, it will not affect the installation.

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0026] Please refer to the attached Figure 1 To the attached Figure 6 The utility model describes a valve with a movable flange.

[0027] Currently, flanged valves are installed with pipe flanges. The pipe flanges are welded to the pipes, and the valve flanges are cast integrally with the valve body. The valve is installed between the two pipes. After welding the two pipe flanges, the axes of the two pipe flange mounting holes are misaligned, causing the valve body flange to misalign with the pipe flange mounting holes, making valve body installation difficult. When the pipeline is buried, rework and rectification are costly and difficult.

[0028] Therefore, the flange-movable valve includes a valve body 2, one end of the valve body 2 is fixedly connected to a fixed flange 3, and the end of the valve body 2 away from the fixed flange 3 is sleeved with a flange 1. The flange 1 can rotate relative to the valve body 2 to be installed with the flange to be docked. The flange structure is installed on the valve body 2 as a separate component, so that the flange 1 can rotate freely relative to the valve body 2. When the valve is installed on the pipeline during construction, even if the flange welded to the pipeline (that is, the flange to be docked) is misaligned and not concentric, the flange 1 can be rotated to make the mounting hole of the flange 1 coincide with the flange hole of the flange to be docked, and then fixed with bolts, which will not affect the installation connection between the valve body 2 and the pipeline.

[0029] An annular groove 21 is provided on the valve body 2, and the flange 1 is sleeved on the annular groove 21 of the valve body 2 to limit the radial and axial position of the flange 1. By sleeved on the annular groove 21, the end face of the flange 1 contacts the side face of the annular groove 21, and the center of the flange 1 contacts the bottom face of the annular groove 21, so that the flange 1 cannot move radially and axially. The flange 1 can only rotate with the valve body 2 as the center. Specifically, when the flange 1 is sleeved on the annular groove 21 of the valve body 2, the flange 1 and the annular groove 21 of the valve body 2 are on the same axis.

[0030] The first surface 111 and the second surface refer to two end surfaces of the flange 1 .

[0031] The flange 1 is assembled from a plurality of flange blocks 11, each of which is provided with fixing holes 13. After the plurality of flange blocks 11 are assembled into the flange 1, the fixing holes 13 on adjacent flange blocks 11 overlap, and the adjacent flange blocks 11 are connected and fixed by fasteners 4 passing through the fixing holes 13.

[0032] Multiple flange blocks 11 are made of the same material and can be assembled by rotating a certain angle. Preferably, the specific number of flange blocks 11 is two, and the two flange blocks 11 are convenient for assembly into the flange plate 1. In other embodiments of the present invention, the specific number of flange blocks 11 can also be other numbers. As long as there are no less than two flange blocks 11, the flange plate 1 can be sleeved onto the valve body 2.

[0033] Multiple flange blocks 11 are assembled into a flange plate 1 on the annular groove 21 of the valve body 2. When installing the flange plate 1 on the valve body 2, multiple flange blocks 11 need to be assembled into a flange plate 1 on the annular groove 21 of the valve body 2 so that the flange plate 1 is connected to the valve body 2.

[0034] Specifically, such as Figure 2 As shown, multiple flange blocks 11 are each provided with abutment grooves 16. After the multiple flange blocks 11 are assembled into a flange plate 1, the multiple abutment grooves 16 are connected to form an annular step groove 17. When the flange plate 1 is sleeved onto the annular groove 21 of the valve body 2, the annular step groove 17 covers the side wall outside the annular groove 21 of the valve body 2, further preventing the flange plate 1 from moving radially and axially along the valve body 2, so that the flange plate 1 can only rotate with the valve body 2 as the center, while ensuring the connection strength between the flange plate 1 and the valve body 2.

[0035] A first step groove 14 and a second step groove 15 are respectively provided at both ends of the flange block 11. After the multiple flange blocks 11 are assembled into the flange plate 1, the first step groove 14 of the flange block 11 is buckled with the second step groove 15 of the adjacent flange block 11, and the second step groove 15 of the flange block 11 is buckled with the first step groove 14 of the adjacent flange block 11. Specifically, a fixing hole 13 is provided on the first step groove 14 and the second step groove 15. When the first step groove 14 of the flange block 11 is buckled with the second step groove 15 of the adjacent flange block 11 and the second step groove 15 of the flange block 11 is buckled with the first step groove 14 of the adjacent flange block 11, the fixing hole 13 of the first step groove 14 coincides with the fixing hole 13 of the second step groove 15, so that the fastener 4 passes through the overlapping fixing holes 13 to connect and fix the adjacent flange blocks 11, so that the flange blocks 11 do not move relative to each other, thereby improving stability.

[0036] Preferably, the first step groove 14 is provided on the first surface 111 of the flange block 11, and the second step groove 15 is provided on the second surface of the flange block 11. In other embodiments of the present invention, the first step groove 14 may also be provided on the second surface of the flange block 11, and the second step groove 15 may also be provided on the first surface 111 of the flange block 11, as long as it can be ensured that the first step groove 14 and the second step groove 15 are respectively located on the two end surfaces.

[0037] Preferably, the fastener 4 is a bolt. After the fixing hole 13 of the first step groove 14 coincides with the fixing hole 13 of the second step groove 15, the bolt is passed through the fixing hole 13 to fix the adjacent flange blocks 11. In other embodiments of the present invention, the fastener 4 can also be a screw, and a thread is provided on the fixing hole 13, so that the fixing hole 13 is screwed to the screw to fix the adjacent flange blocks 11. As long as the fixing holes 13 coincide with each other, the adjacent flange blocks 11 are connected and fixed by the fastener 4, it can be sufficient.

[0038] Furthermore, mounting holes 12 are provided on both the first step groove 14 and the second step groove 15. When the first step groove 14 of the flange block 11 is engaged with the second step groove 15 of the adjacent flange block 11, and the second step groove 15 of the flange block 11 is engaged with the first step groove 14 of the adjacent flange block 11, the mounting hole 12 of the first step groove 14 coincides with the mounting hole 12 of the second step groove 15, so that the adjacent flange blocks 11 of the flange plate 1 share the mounting hole 12, thereby improving the tensile strength of the flange plate 1, so that when the mounting hole 12 is used to connect and install with the flange to be docked, the connection strength is higher. In other embodiments of the present invention, the mounting hole 12 can also be provided at other parts of the flange block 11, so that when it is required to ensure that the mounting hole 12 can pass through the bolt and be connected to the flange to be docked,

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
