Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to a valve elbow flange hole alignment device. Background Art

[0002] At present, various pipes are often used in basic projects such as chemical industry, construction, water supply and drainage, petroleum, plumbing, refrigeration, fire protection, and electricity. Pipes are generally straight, which requires a pipe elbow. When the flow channel diameter is large, it is difficult to directly cast the elbow. It is usually made by welding flanges and elbows. However, in this way, the flange holes on the flanges at both ends are difficult to align. The use of misaligned elbows will make the flange holes on the pipes connected to the two ends of the elbows different in angle, resulting in different installation angles of the valves on the pipes on both sides, increasing the floor space and affecting the appearance. Although a clamp can be used for alignment, one clamp can only correspond to one size of elbow, and multiple elbows require multiple clamps, which is very troublesome. Summary of the invention

[0003] In summary, in order to overcome the deficiencies of the prior art, the present invention provides a valve elbow flange hole alignment device that can be used to align flange holes of valve elbows of various sizes.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a valve elbow flange hole alignment device, comprising a hole plug mechanism, a first buckle, a second buckle and a third buckle, the first buckle comprising a first connecting portion and a first rotating portion, the first rotating portion is provided with a first rotating shaft, the second buckle is provided with a second connecting portion and a second rotating portion, the second connecting portion is provided with a first connecting groove, the first connecting groove cooperates with the side of the first rotating portion provided with the first rotating shaft, a gap is left between the upper top surface of the first rotating portion and the first connecting groove, the second connecting portion is provided with a first rotating groove cooperating with the first rotating shaft, the first rotating groove is a straight slot, the second rotating portion is provided with a second rotating shaft, the second rotating shaft cooperates with the first rotating groove, the third buckle is provided with a second connecting groove, the second connecting groove cooperates with the side of the second rotating portion provided with the second rotating shaft, a gap is left between the upper top surface of the second rotating portion and the second connecting groove, the third buckle is provided with a second rotating groove cooperating with the second rotating shaft, the second rotating groove is a straight slot, and the first connecting portion and the third buckle are respectively detachably connected to one of the hole plug mechanisms.

[0005] With such arrangement, the first rotating part on the first buckle can be inserted into the first connecting groove on the second buckle, and the first rotating shaft on the first rotating part is inserted into the first rotating groove on the second connecting part to connect the first buckle with the second buckle, and the second buckle connected thereto is connected with another second buckle in the same manner. When the length reaches the required length, the second buckle at the end can be connected with the third buckle in the same manner, and the first rotating shaft and the second rotating shaft are movable in the first rotating groove and the second rotating groove respectively. Since the first rotating groove and the second rotating groove are both straight grooves, the first buckle and each second buckle have an movable distance between the centers of the straight grooves, which can adapt to various lengths of bent pipes, and the device can be further adjusted by adjusting the number of second buckles. The upper or lower limit of the operating length, since there are gaps between the upper top surface of the first rotating part and the upper top surface of the second rotating part and the first connecting groove and the second connecting groove respectively, a first clip and each second clip can rotate around the first rotating shaft and the second rotating shaft, so that it can fit elbows of various angles and lengths. The connecting part of the first clip and the third clip are respectively connected to a hole plug mechanism, and the hole plug mechanism corresponds to the flange hole. The two hole plug mechanisms are inserted into the flange holes at both ends. Since the first connecting groove and the second connecting groove are respectively matched with the side of the first rotating part with the first rotating shaft and the side of the second rotating part with the second rotating shaft, the device will not make an axial swing of the rotating shaft, ensuring that the clip is always perpendicular to the flange and the flange hole will not be offset.

[0006] Furthermore, the first connecting portion is provided with a third connecting groove, the third buckle is provided with a fourth connecting groove, and the third connecting groove and the fourth connecting groove are rectangular grooves that cooperate with the positioning bolt.

[0007] With such arrangement, the hole plug mechanism can slide in the third connecting groove and the fourth connecting groove, and can adapt to flanges with various different center distances.

[0008] Furthermore, the hole plug mechanism includes a chassis, a spiral disk and a movable claw, the third connecting groove and the fourth connecting groove are respectively slidably connected to a chassis, one end face of the spiral disk is provided with spiral gear teeth, the other end face of the spiral disk is provided with a threaded hole, the threaded hole is provided with a positioning bolt matching therewith, the movable claw includes a claw body and a movable claw, the claw body is provided with a movable groove matching therewith, the end face of one side of the chassis is provided with a claw groove, and the chassis is provided with a through hole matching the threaded hole.

[0009] With such arrangement, the movable groove of the movable claw is fitted and connected to the claw groove on the chassis with the spiral gear teeth on the spiral disk. When the spiral disk rotates forward along the spiral gear teeth, because the claw body of the movable claw is restricted in the claw groove, the spiral gear teeth will exert a radial force on the movable groove, causing the movable claw to slide outward along the claw groove until the movable claw hits the flange hole. The movable claw can be used on flange holes of various sizes. When disassembling, the spiral disk is reversed along the spiral gear teeth to retract the movable claw inward along the claw groove, and the movable claw is away from the flange hole.

[0010] Furthermore, the number of the movable claws is three.

[0011] With such arrangement, the three movable claws are easier to be positioned at the center of the flange hole and are less likely to be eccentric.

[0012] Furthermore, the chassis is provided with a first sliding block that cooperates with the third connecting groove and the fourth connecting groove.

[0013] With such arrangement, the hole plug mechanism slides more smoothly and the chassis will not rotate along with the spiral disk.

[0014] Furthermore, the hole plug mechanism also includes a double plug rack, which is provided with a second slider slidably connected to the third connecting groove and the fourth connecting groove, and the second slider is provided with sliding grooves on both sides that cooperate with the first slider, and the sliding grooves are perpendicular to the third connecting groove and the fourth connecting groove.

[0015] With such arrangement, when the flange hole is not on the quadrant line, a double plug rack can be used to connect with the first clip and the third clip respectively, and two hole plug devices are connected to each double plug rack. Since the slide groove is perpendicular to the connecting groove, the common planes of the flange holes corresponding to the hole plug devices on the flange plates on both sides are perpendicular to the devices, and the flange plates enter the alignment state, successfully aligning the flange plates when the flange holes are not on the quadrant line.

[0016] Furthermore, it also includes a handle, and a column is provided on one end surface of the spiral disk having the spiral gear teeth, and the column and the handle are arranged in linkage.

[0017] With such arrangement, the rotation of the spiral disk can be controlled by the handle, which is more labor-saving, and the column enables the handle to be installed outside the flange, making it easier to exert force.

[0018] Furthermore, a square boss is provided on the top of the column, and a square groove matching with the square boss is provided at one end of the handle.

[0019] With such a configuration, the spiral disk can be applied with force simply by inserting the square groove into the square boss, and can also be easily removed when disassembling, which is very convenient.

[0020] Furthermore, the handle is configured as a hand wheel.

[0021] This arrangement makes it easier to grasp the handle, the contact area is larger when holding it, and it is easier to apply force.

[0022] Furthermore, the upper top surfaces of the first rotating part and the second rotating part are inclined surfaces.

[0023] Such an arrangement ensures that the device does not make axial swing of the rotating shaft during rotation, while increasing the rotation angle, thereby preventing the upper top surface from being blocked by the connecting groove and being unable to continue rotating.

The first connecting part 201 and the third buckle 4 are respectively detachably connected to one of the hole plug mechanisms 1.

[0042] With such arrangement, the first rotating portion 202 on the first buckle 2 can be inserted into the first connecting groove 3011 on the second buckle 3, and the first rotating shaft 2021 on the first rotating portion 202 is inserted into the first rotating groove 3012 on the second connecting portion 301 to connect the first buckle 2 and the second buckle 3, and the second buckle 3 connected thereto is connected to another second buckle 3 in the same manner, and when the length reaches the required length, the second buckle 3 at the end can be connected to the third buckle 4 in the same manner, and the first rotating shaft 2021 and the second rotating shaft 3021 are movable in the first rotating groove 3012 and the second rotating groove 402 respectively, and since the first rotating groove 3012 and the second rotating groove 402 are both straight grooves, the first buckle 2 and each second buckle 3 have an movable distance between the centers of the straight grooves, which can adapt to various lengths of curved pipes, and can be further adjusted by adjusting the number of second buckles 3. The upper or lower limit of the operating length of the joint device is determined. Since there are gaps between the upper top surface of the first rotating part 202 and the upper top surface of the second rotating part 302 and the first connecting groove 3011 and the second connecting groove 401 respectively, a first clip 2 and each second clip 3 can rotate around the first rotating shaft 2021 and the second rotating shaft 3021, so that it can fit the curved pipes of various angles and lengths. The connecting part of the first clip 2 and the third clip are respectively connected with a hole plug mechanism 1, and the hole plug mechanism 1 corresponds to the flange hole. The two hole plug mechanisms 1 are inserted into the flange holes at both ends. Since the first connecting groove 3011 and the second connecting groove 401 are respectively matched with the side of the first rotating part 202 with the first rotating shaft 2021 and the side of the second rotating part 302 with the second rotating shaft 3021, the device will not make axial swing of the rotating shaft, ensuring that the clip is always perpendicular to the flange and the flange hole will not deviate.

When the spiral disk 102 rotates forward along the spiral gear 1021, because the claw body 1031 of the movable claw 103 is restricted in the claw groove 1011, the spiral gear 1021 will exert a radial force on the movable groove 10311, so that the movable claw 103 slides outward along the claw groove 1011 until the movable claw 1032 hits the flange hole. The movable claw 103 can be used on flange holes of various sizes. When disassembling, the spiral disk 102 is reversed along the spiral gear 1021, so that the movable claw 103 is retracted inward along the claw groove 1011, and the movable claw 1032 is away from the flange hole.

Since the slide groove 1061 is perpendicular to the connecting groove, the common planes of the flange holes corresponding to the hole plug devices 1 on the flanges on both sides are perpendicular to the device, and the flanges enter an alignment state, successfully aligning the flanges when the flange holes are not on the quadrant line.
