Abstract
Description
Technical Field
[0001] The invention relates to the technical field of pipeline installation, and in particular to a combined pipeline opening saddle. Background Art
[0002] The pipeline pressure opening saddle is a device used to connect the pipeline to the branch pipe. It is widely used to install monitoring equipment such as pressure gauges and flow meters on the pipeline, and can also be used to install branch pipes. Traditional saddles are composed of two ductile iron, semicircular shells, rubber gaskets and fasteners, called upper saddles and lower saddles respectively. The upper saddle is provided with threaded holes or flange mounting ports. The rubber gasket is fixed on the upper saddle, and the upper and lower saddles are fastened by bolts to clamp and seal the pipeline. Since the upper and lower saddles are usually ductile iron or stainless steel castings, it is well known that castings require corresponding molds to be produced. In this way, different molds are required when dealing with different pipe diameters, which also causes certain development costs and a certain development cycle. Especially for pipe diameters with relatively low market demand, it is not economical. In addition, since castings are rigid, they also need to be distinguished when facing pipes of the same nominal diameter but different materials. For example, the outer diameter of the ductile iron pipe of DN200 engineering diameter is 222 mm, the PE pipe is 200 mm, and the concrete pipe is 260 mm. This causes two problems: first, due to poor versatility, it causes inconvenience to users during use; second, it causes an increase in the development cost, production cost, inventory cost and management cost of the manufacturer. Summary of the invention
[0003] In order to solve the technical problems existing in the background technology, the present invention proposes a combined pipe opening saddle.
[0004] The present invention provides a combined pipe opening saddle, comprising: a base, a fixing belt, and a connecting piece, wherein:
[0005] The base has a neck and a hole passing through the neck; a through hole is arranged in the middle of the fixing belt for the neck of the base to pass through; the head and tail of the fixing belt are connected by a connecting piece to press the base onto a designated pipe.
[0006] Preferably, the fixing belt is one, and connection holes are provided at the ends of both ends of the fixing belt; the connecting piece includes bolts and nuts, and the bolts pass through the connection holes at both ends of the fixing belt in turn and are then locked by the nuts.
[0007] Preferably, the fixing strap comprises an upper fixing strap and a lower fixing strap, the ends of both ends of the upper fixing strap and the lower fixing strap are provided with connecting holes, and the through holes are provided on the upper fixing strap; there are two groups of connecting pieces, which correspond to the connecting holes at both ends of the upper fixing strap and the lower fixing strap respectively; the connecting pieces comprise bolts and nuts, and the bolts are passed through the connecting holes on the upper fixing strap and the lower fixing strap in turn and then locked by the nuts.
[0008] Preferably, both ends of the fixing belt are respectively provided with a transversely arranged limit column; the connecting hole is a long waist hole, and the ends of both ends of the fixing belt are folded toward their center parts to wrap the corresponding limit column inside its end, and the connecting hole forms an overlapping area on one side of the limit column; the bolt passes through the overlapping area to form a connection.
[0009] Preferably, a sealing gasket groove is provided at the bottom of the base, and a sealing gasket is provided in the sealing gasket groove.
[0010] Preferably, the end surface of the base located outside the neck is a curved surface.

Compared with the prior art, this structural design has the following advantages:
[0015] 1. The fixing belt does not require mold opening, and its length can be selected according to the outer diameter of the pipe, so the mold opening cost can be greatly reduced. The fixing belt has good flexibility and can be applied to various types of pipe requirements. Therefore, in terms of manufacturing flexibility, this solution is superior to traditional castings.
[0016] 2. Compared with the traditional saddle, the base is smaller in size. Therefore, its casting and machining are more convenient than the traditional saddle. And because of its smaller size, it is more adaptable to changes in the outer diameter of the pipe and can be used on pipes of different calibers. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Reference Figure 1-4 The present invention provides a combined pipe opening saddle, comprising: a base 10, a fixing belt, and a connecting piece 40, wherein:
[0025] The base 10 has a neck 11 and a hole passing through the neck 11; the fixing belt is a flexible metal belt (preferably a stainless steel belt), and a through hole 21 is provided in the middle of the fixing belt for the neck 11 of the base 10 to pass through; the head and tail of the fixing belt are connected by a connector 40 to press the base 10 onto the designated pipe 50. The specific installation method is as follows:
[0026] During installation, the base 10 is placed on the pipe 50, the through hole 21 on the fixing belt is put on the neck 11 of the base 10, and then the fixing belt is connected end to end using the connecting piece 40 to tightly fix the fixing belt on the pipe 50, and the base 10 is firmly pressed between the fixing belt and the pipe 50 by the fixing belt, thereby forming a fixation.
[0027] The fixing belt design methods in this embodiment include at least the following two methods:
[0028] The first type: the fixing belt is a single belt (its structure refers to the upper fixing belt 20 in the attached figure), both ends of which are provided with connecting holes, and the connecting member 40 includes bolts and nuts, and the bolts are sequentially passed through the connecting holes at both ends of the fixing belt and then locked by nuts.
[0029] The second type: the fixing belt includes an upper fixing belt 20 and a lower fixing belt 30, and the ends of the upper fixing belt 20 and the lower fixing belt 30 are provided with connecting holes, and the through hole 21 is set on the upper fixing belt 20; there are two groups of connecting members 40, which correspond to the connecting holes at both ends of the upper fixing belt 20 and the lower fixing belt 30 respectively; the connecting member 40 includes bolts and nuts, and the bolts pass through the connecting holes on the upper fixing belt 20 and the lower fixing belt 30 in turn and are locked by nuts.
[0030] Reference Figure 5-6In this embodiment, both ends of the fixing belt are respectively provided with horizontally arranged limit columns 22, 31; the connecting hole is a long waist hole, and the ends of the two ends of the fixing belt are respectively folded toward the center to wrap the corresponding limit columns 22, 31 inside the ends, and the connecting hole forms an overlapping area on one side of the limit columns 22, 31; the bolt passes through the overlapping area to form a connection. On the one hand, this structural design can increase the strength of the connection part, and on the other hand, by changing the outer diameter of the limit columns 22, 31 and / or the bolts, the inner diameter of the fixing belt after the end is connected can be changed, so that during on-site installation, the user can fine-tune the inner diameter of the fixing belt as needed to adapt to the requirements of the outer diameter of the pipe 50 and the installation tightness.
[0031] In addition, the present embodiment further provides a sealing gasket 13 groove at the bottom of the base 10, and a sealing gasket 13 is provided in the sealing gasket 13 groove. The lower surface of the base 10 is an arc surface. The end surface of the base 10 located outside the neck 11 is provided as an arc surface. The sealing gasket 13 groove can firmly limit the sealing gasket 13 inside to prevent it from moving, thereby ensuring the sealing between the base 10 and the pipe 50. The arc surface design of the lower surface of the base 10 can adapt to the arc surface of the outer wall of the pipe 50 and better fit with the pipe 50; and the arc surface design of the outer periphery of the neck 11 can fully fit with the inner side of the fixing belt when pressed.
[0032] Reference Figure 7 As shown in Table 1, the structural design of the combined pipe opening saddle allows some pipes with small differences in arc height H on the outer diameter DE to replace each other, further reducing mold development and facilitating customer use.

[0034]
[0035] In summary, the present invention has the following advantages compared with the prior art:
[0036] 1. The fixing belt does not require mold processing, and its length can be selected according to the outer diameter of the pipe 50, so the mold cost can be greatly reduced. The fixing belt has good flexibility and can be applied to various types of pipes 50. Therefore, in terms of manufacturing flexibility, this solution is superior to traditional castings.
[0037] 2. The base 10 is smaller in size than the traditional upper saddle. Therefore, its casting and machining are more convenient than the traditional upper saddle. Due to its smaller size, it is more adaptable to changes in the outer diameter of the pipe 50 and can be applied to pipes 50 of different calibers.
[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
