Constant force spring customized non-standard tension spring high cost performance

by:Yongqiang     2021-01-06
Purpose and scope of application:
this standard applies to the displacement range for VS ( 0~180mm) TD ( 0 ~ 120毫米) , load range is 154 ~ 217384 n, using temperature range - Steam-water variable spring of 20 ℃ ~ 200 ℃.

the relief valve position determination of steam-water pipes of the spring: relief valve nozzle under external load caused by the bending moment requires small as far as possible, so as not to affect the performance of the valve body deformation. In addition to consider when setting stent pipeline under the gravity load, also should pay attention to when the discharge fluid reaction force and its direction. Safety valve outlet pipe bracket of a root point should not take root in the flexible large steel structure, at the same time supporting points of vertical thermal displacement should be small as far as possible. On the higher temperature of pipe, valve export levels should be long enough, avoid stents escapes. Relief valve suddenly open, prone to vibration, especially large diameter, large differential pressure relief valve should be paid attention to vibration control, the outlet pipe of gas-liquid two phase, more attention should be paid to vibration control and avoid water hammer.

spring factory before they go out of the steam-water setting, when installed on the pipeline and equipment, adjust the relevant thread, to fix the quotas for marketing off, the spring is the actual bearing design requirements of cold load.

steam-water pipe spring pipe bracket structure form of design and selection is an important part in the design of pipe system, pipe bracket in addition to support the piping weight, constant force spring hanger, special pipe bracket can balance the piping forces, limit line displacement and absorption of vibration, steam-water VS spring, in the pipe system design, reasonable structure of the pipe bracket, correct selection and arrangement, can improve the stress distribution of the pipeline and the force of pipe rack, ensure the safe operation of the pipe system, and extend its service life.
