Butterfly valve supporting steel limit telescope material description
Butterfly valve supporting steel limit telescope material description
In the pipeline can effectively compensate and relieve the pipeline and blind plate thrust, and can facilitate the installation and maintenance of the pump, valve replacement, the most ideal supporting products for the pipeline installation and transportation industry. Because this series of products is a metal manufacturing products, it has a high tensile and compressive strength, soft sealing performance is superior, easy to load and unload and other functions, is often used in electric power, metallurgy. Water supply and drainage and sewage treatment industries, the main role in the connection between the pump and the valve and pipeline.
Steel limit expansion joint can prevent the pipeline from leakage or damage due to excessive displacement of the compensation joint, mainly used in the allowable displacement range to absorb the axial displacement and bear the axial pressure thrust of the pipeline loose-fitting connection. The product is suitable for transporting seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, lubricating oil, finished oil, air, gas, steam and granular powder at temperatures not higher than 250 degrees.
The pipe in the product is divided into cast iron (HT), galvanized (DX) and steel (SF). The working pressure is divided into PN6, PN10 and PN16. When installing the product, adjust the length of the connection between the two ends and the flange, tighten the gland bolts diagonally and evenly, and then adjust the limit nuts, so that the pipe can expand and contract freely within the expansion range and lock the expansion volume to ensure the safe operation of the pipeline. It has the following roles: compensate and absorb pipeline axial, lateral and angular thermal deformation; absorb equipment vibration and reduce the impact of equipment vibration on the pipeline; absorb the deformation of the pipeline by earthquake and ground subsidence.
