variable spring hanger (T, TH, VS, TD)

Spring hanger is mainly used for power plant steam piping or boiler equipment, heat is generated in the operation of its equipment displacement device. Calculated according to the pipeline to determine the force of spring hangers work and thermal displacement requirements.
First, the purpose and principles
Variable spring hanger is mainly socketless fitting used for power plant steam piping or boiler equipment, heat is generated in the operation of its equipment displacement device. Calculated according to the pipeline to determine the force of spring hangers work and thermal displacement requirements, the factory will spring hanger design load for tuning in accordance with: the spring preload and set the cold load position; also marked when cold Theoretic working position.
Spring hanger factory carried out in the factory setting, when mounted to the pipes and equipment after adjustment for such threads will disengage the lock pin, then spring is the design of the actual load required for cold load.
Second, model, type
Variable spring hanger has four series, mainly by the Northwest Electric Power Design Institute of T1, T2, T3, T4, T5 series, East China Electric Power Design Institute of TH1, TH2, TH3 series, TD Series ( JB/J8130.2-1999) and Chemical Design Institute VS series, the series of the same basic characteristics, carrying capacity 20daN-21000daN. Structure are suspended, and parallel suspension bearing type bearing type.
(Three), T, TH structure and model representation:
The form is divided into the middle of the installation hanger connection to connect the upper and lower hanger spring hanger spring TH 1 TH 2, TH 3 three models holder spring.
TH 1 is divided into A, B, C are three types;
TH 1 A (T1) is connected to a single ear hanger spring;
TH 1 B (T2) is connected binaural spring hanger;
TH 1 C for the threaded connection hanger spring;
These three types of china hydraulic hose springs, primarily used for hanging in the beam, the beam tube on the backplane.
TH 2 (T3) for installation in steel beams;
TH 3 (T4) is mainly used in the basic shelving, steel beams, slabs;
T5 parallel suspension type.
(Four), VS, TD structure and model representation:
Variable spring hangers primarily by helical springs, displacement indicator board, shell and elastic nut and other parts.
Variable spring hanger according to the installation, divided into A, B, C, D, E, F, G seven kinds of patterns.
A type ---- on threaded suspension type;
Type B ---- single ear hanging type;
C-type ---- Binaural suspension type;
Type D ---- on adjustable shelving type;
E-type ---- Next adjustable shelving type;
F-type ---- supporting shelving type;
G-type ---- Parallel suspension type;
