弹簧支吊架主要用于电厂汽水管道或锅炉设备、在运行中产生热位移及其设备装置上。根据管道受力情况计算确定的弹簧支吊架工作和热位移要求，将弹簧支吊架按照设计荷载进行整定：即弹簧预压并所定冷态荷载位置上;同时标上冷态时的理论工作位置。
Boiler steaming-water pipe or in steam-water spring is mainly used for power equipment, the thermal displacement and its equipment in the operation of the device. Calculated and determined according to the pipeline stress situation of the work and the thermal displacement, steam-water spring will be carried out in accordance with the design load setting steam-water spring: the spring preloading and position set by the cold load; At the same time, the theoretical position to be in the cold.
一、弹簧支吊架在出厂前制造厂方进行了整定，当安装了到管道和设备上后，作有关螺纹调整，将锁定销脱开，这时弹簧的实际承载就是设计所要求的冷态荷载。
A steam-water, spring manufacturing factory for setting before they go out, when installed on the piping and equipment adjust about the thread, the locking pin off, the spring is the actual bearing design requirements of the cold load.
二、型号、种类 可变式弹簧支吊架有四大系列，主要是由西北电力设计院设计的 T1、T2、T3、T4、T5型系列、 华东电力设计院设计的TH1、TH2、TH3型系列、TD系列(JB/J8130.2-1999) 化工设计院设计的VS系列，其系列的基本特性相同，承载力为20daN-21000daN。 结构形式主要有悬吊式、支承式和并联悬吊支承式。
Type, type variable type spring hanger has four big series, mainly by the northwest electric power design institute of design of T1, T2, T3, T4, T5 series, east China electric power design institute of design of TH1, TH2, type "TH3" series, the TD series (JB/J8130.2-1999) the VS series of chemical industry design institute of design, the series of the basic characteristics, the same bearing capacity of 20 Dan Dan - 21000. Structure forms mainly include the suspension type, bearing type and parallel suspension bearing type.
三、T、TH结构形式和型号表示方法：本吊架根据安装形式分为中间连接吊架弹簧TH1 、上下连接吊架弹簧TH2 、支架弹簧TH3 三种型号。 TH 1 又分为A、B、C三种类型; TH 1 A( T1 )为单耳连接吊架弹簧; TH 1 B( T2 )为双耳连接吊架弹簧; TH 1 C为螺纹连接吊架弹簧; 这三种类型弹簧，主要用于悬挂在钢梁、管梁、底板上。 TH 2 ( T3 )适用于安装在钢梁上; TH 3 ( T4 )主要用于搁置在基础、钢梁、楼板上; T5 并联悬吊型。
T, TH structure form and model representation: the intermediate connecting suspension spring hanger according to the type of installation is divided into TH1, up and down link hanger spring TH2, support spring "TH3" three kinds of models. TH 1 is divided into A, B, C three types; TH 1 A (T1) is A single ear connected spring hanger; TH 1 B (T2) as the binaural link spring hanger; TH 1 C for threaded hanger springs; The three types of spring, is mainly used for hanging in the steel girder, illustrated the, on the floor. TH 2 (T3) is suitable for installation on the steel beam; TH 3 (T4) is mainly used to put on the foundation, beam, floor slab; T5 parallel suspension type.
四、VS、TD结构形式和型号表示方法： 可变弹簧支吊架主要由圆柱螺旋弹簧、位移指示板、壳体及松紧螺母等零件组成。可变弹簧支吊架按安装方式的不同，分为A、B、C、D、E、F、G七种型式。 A型----上螺纹悬吊型; B型----单耳悬吊型; C型----双耳悬吊型; D型----上调节搁置型; E型----下调节搁置型; F型----支撑搁置型; G型----并联悬吊型。
VS, TD structure form and model representation: variable spring pipe-hanger is mainly composed of cylindrical helical spring, dashboards, displacement and elastic nut shell parts. Variable steam-water spring according to the different installation way, divided into A, B, C, D, E, F, G seven types. Type A, type of thread hanging; B - monaural suspension type; C type - ears hanging type; D - type adjustment on hold; E - regulation under the suspended type; F type - type support on hold; G type - parallel suspension type。
