Appendix A of this standard is an informative appendix, and Appendix B is a normative appendix. This standard is proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Technical Committee for Boiler Standardization (CSBTS/TC73). The drafting units of this standard are Dalian Spring Factory and Harbin Boiler Factory Co., Ltd. The main drafters of this standard are Lei Donghui, Du Benju, Wang Huating, Du Xianglin, Sun Xifa and Zhuang Songping. JB/T10357—2002
JB/T10357—2002
Constant force support and suspension channel is an indispensable and important device in the support and suspension system of thermal pipelines in thermal power plants and oil refining and chemical engineering projects. The elastic components in its structure currently include cylindrical helical springs and discs. This standard uses discs as elastic elements, thus reducing the volume and weight of the support and suspension bracket, facilitating the spatial arrangement of the project and reducing the project cost. Referring to similar foreign standards and domestic design selection, this standard cancels the single ear plate rooting method compared with JB/T8130.1-1999 "Constant Force Spring Support and Hanger".
1 Scope
Constant force disc spring supports and hangers
JB/T 10357--2002
This standard specifies the series specifications, dimensional parameters, manufacturing, inspection technical requirements and selection methods of constant force disc spring supports and hangers: This standard is applicable to constant force disc spring supports and hangers with a load range of 123N~315991N and a displacement range of 50mm~~400mm. 2 Normative references
The provisions in the following documents become the provisions of this standard through reference in this standard. All subsequent amendments (excluding errata) or revisions to dated references are not applicable to this standard. However, parties to agreements based on this standard are encouraged to study whether the latest versions of these documents can be used. For undated references, the latest versions are applicable to this standard. GBT1972-1992 Disc spring (negDIN2092: 1990: DIN2093: 1990) 3 Structure, type
3.1 The constant force disc spring support and hanger is mainly composed of a fixed frame, a rotating frame, a fixed pin, a rooting top plate (or ear plate, a loose medium nut, a disc spring group and a cover. The typical structure is shown in Figure 1.
1-rotating frame: 2-rooting bolts: 3-fixed frame: 4-displacement indicator: 5-locking pin: disc spring group and cover: 7-plate: 8-suspender bolt, 9-loose nut: 10--spindle. Figure 1 Structure diagram of flat constant force disc spring support and hanger
JB/T 103572002
3.2 The types of constant force disc support and hanger are divided into three types: horizontal type (PDA, PDB, PDE), vertical type (LDA, LDB, LDE) and seat type (PDZ, LDZ, LDZb). The support and hanger methods and load and displacement specifications are shown in Table 1.

Note 1: For PDB and LDB types, the single screw root must be fixed on the steel beam. Method 2: The manufacturer's supply does not include the suspension rod bolts below the loose nut. 3.3 Typical examples of constant force disc spring supports and hangers are shown in Appendix A. 4 Load and displacement series

4.1 Constant force disc spring supports and hangers can be selected according to the load and displacement series table. Among them, PDA, PDB, PDE, PDZ type supports and hangers are The load and displacement series of the bracket are shown in Table 2, and the load and displacement series of the LDA, LDB, LDE and LDZ type brackets are shown in Table 3. 4.2 The displacement, load value and code of the constant disc spring bracket are determined in B.1.4, B.1.5 and B.1.6 in Appendix B respectively. 5 Model Representation Method
The model of the constant disc spring bracket consists of 6 parts:
Bolt specification of the hanger, indicated by M××: - Displacement direction, X indicates downward, S indicates upward: Standard load value, unit is N. Indicated by Arabic numerals: Standard displacement value, unit is mm, in Arabic numerals: Bracket code, in Arabic numerals: Bracket type code, in two Chinese pinyin letters and one English letter. Example 1: PDA40-[60/24647 x-M36 means a horizontal A-type number 40, standard displacement value 160mm, standard load value 24647N, displacement direction downward, and rod bolt specification M36 constant force disc support. Example 2: LDB55-200/4813S-M64×4 means a vertical B-type number 55, standard displacement value 200tmm, standard load value /74813N, displacement direction upward, and rod bolt specification M64X4 constant force disc support. 3
