[0019] An adjustable multi-size pipeline spacer ring for ductile cast iron pipeline, which comprises a spacer ring body 1, which is an arc-shaped body of elastic material, and is oppositely or overlappingly arranged at both ends, and the gap between the two ends is an opening 2, and the arc-shaped inner wall of the spacer ring body 1 is a pipeline contact surface, and the circumference between the two ends of the inner wall is not greater than the outer circumference of the to-be-installed end part of the matched pipeline.

[0020] Optionally, the elastic material can be high-elasticity stainless steel or polyamide composite material;

[0021] In order to prevent the spacer ring from scratching the ductile cast iron pipeline during transportation, especially when stainless steel material is used and the corners are relatively sharp, the inner wall two sides and the outer circumference two sides of the spacer ring body 1 can also be rounded.

[0022] For reference, the width of the spacer ring body 1 can be 20 mm.

[0023] Example 1:

[0024] As Figure 1As shown, the two ends of the spacer ring body 1 are oppositely arranged, and the gap between the two ends is the opening 2. In use, the opening 2 is slightly opened and then sleeved on the outer wall of the key end portion. The middle part of the two side surfaces of the spacer ring body 1 is provided with a groove 3. The main function of the groove 3 is to save materials and reduce unnecessary expenses.

[0025] Embodiment 2:

[0026] As shown, the two ends of the spacer ring body 1 are oppositely arranged, and the gap between the two ends is the opening 2. In use, the opening 2 is slightly opened and then sleeved on the outer wall of the key end portion. The middle part of the two side surfaces of the spacer ring body 1 is provided with a groove 3. The main function of the groove 3 is to save materials and reduce unnecessary expenses. Figure 2 As shown, the two ends of the spacer ring body 1 are oppositely arranged, and the gap between the two ends is the opening 2. In use, the opening 2 is slightly opened and then sleeved on the outer wall of the key end portion. The middle part of the two side surfaces of the spacer ring body 1 is provided with a groove 3. The main function of the groove 3 is to save materials and reduce unnecessary expenses.

[0027] Figure 3 As shown, the two ends of the spacer ring body 1 are oppositely arranged, and the gap between the two ends is the opening 2. In use, the opening 2 is slightly opened and then sleeved on the outer wall of the key end portion. The middle part of the two side surfaces of the spacer ring body 1 is provided with a groove 3. The main function of the groove 3 is to save materials and reduce unnecessary expenses.

[0028] Embodiment 3:

[0029] The groove 3 and the dovetail part 4 in the above two embodiments can also exist at the same time, as shown, the two ends of the spacer ring body 1 are oppositely arranged, and the gap between the two ends is the opening 2. The two ends of the spacer ring body 1 are also provided with triangular dovetail parts 4. The outer side surface of the dovetail part 4 is coplanar with the side surface of the spacer ring body 1, and the inclined edges of the two dovetail parts 4 are parallel to each other. The middle part of the two side surfaces of the spacer ring body 1 is provided with a groove 3. Figure 4 In order to avoid affecting the strength of the spacer ring, it is further preferred that the depth of the groove 3 should not exceed one fourth of the width of the spacer ring body 1, and the width of the groove 3 should not exceed one third of the thickness of the spacer ring body 1. For reference, when the width of the spacer ring body 1 is 20mm and the thickness is 7mm, the width of the groove 3 can be 2mm and the depth can be 4mm. The groove wall is preferably parallel to the inner and outer walls of the spacer ring body 1. For the spacer ring body 1 with dovetail part 4, the groove 3 should not be opened to the two end parts, because it will cause the end part to be too low in strength. Specifically, the groove 3 can be set not to exceed the middle part of the outer side surface of the dovetail part 4, and the groove 3 at the dovetail part 4 can keep the groove bottom coplanar with the original groove bottom, or gradually reduce the groove depth. Since the main function is to save materials, it can also be improved at will without affecting the strength.

[0030] Embodiment 4:

[0031]

[0032] ​​In the above three embodiments, the spacer ring body 1 can be composed of a plurality of arc segments that are detachably connected, so as to increase or decrease the number of arc segments according to the outer diameter of the pipe to be installed, thereby realizing modular assembly and adapting to various pipe diameters and reducing the required inventory; specifically, the detachable connection can be achieved by providing buckles at both ends of the arc segment and connecting the buckles through elastic claws, which facilitates quick assembly and disassembly, and of course other known detachable connection structures can also be used, such as plug-in connection, bolt connection, chain connection, etc.

[0033] For reference, taking example of the embodiment 1, for the convenience of quantification, the ideal state of the spacer ring body 1 is described as being broken into a circular ring, and the spacer ring has an inner diameter, at this time, DN80, DN100, DN200, DN250 and DN300 can share the structure composed of a plurality of arc segments that are detachably connected, specifically, for the DN80 pipe, the inner diameter of the spacer ring can be 101.5±2.5mm, for the DN100 pipe, the inner diameter of the spacer ring can be 120±2.5mm, for the DN200 pipe, the inner diameter of the spacer ring can be 222±2.5mm, for the DN250 pipe, the inner diameter of the spacer ring can be 269±2.5mm, and for the DN300 pipe, the inner diameter of the spacer ring can be 325±2.5mm, and for these different inner diameters, the number of arc segments can be increased or decreased to achieve the desired diameter, and due to the existence of the opening 2 and the elastic material, the spacer ring can better adapt to different pipe diameters and errors.

[0034] For the spacer ring provided with the dovetail part 4, it can better adapt to various pipe fittings while allowing more machining error allowance of the outer diameter of the ductile iron pipe to be installed based on the embodiment 2.
