Application of large diameter rubber flexible joints

Rubber flexible joints are used in the connection of drainage ducts and air ducts or exhaust ducts, because the ventilation ducts. Duct. The difference in air pressure in the exhaust duct will lead to vapor collusion, when the duct or exhaust duct vapor is large will be injected into the ventilation pipe, blocking the ventilation pipe odor rise, ruining the balance of the drainage equipment connected to the rubber flexible joint; when the air pressure in the duct or exhaust duct bell, the ventilation pipe vacuum will also be injected into the duct or exhaust duct, if into the house will be environmental pollution of indoor air quality hazards Air quality index. The rubber flexible joint is an indispensable machine and equipment in the field of water purification and sewage treatment in China, and it plays an indispensable role in the whole stage of sewage treatment.
The application of rubber flexible joints is indeed the assembly of pipeline projects. The application of rubber flexible joints is indeed a great convenience for the assembly of pipeline projects. In terms of transportation methods, rubber flexible joints are usually used to bear pressure on the pipeline, so there are high regulations on the sealing characteristics of the raw materials, and at this stage, the products usually choose high-quality sealing rings to deal with this problem. However, for the rubber flexible joints, to ensure that the pipeline thermal expansion and contraction and the resulting offset adjustment, usually designed and programmed the amount of arbitrary expansion and contraction, within its reasonable expansion and contraction can still maintain the sealing characteristics of the expansion joints, but also thus the strict requirements for the pipeline and assembly of its said connection.
 
Large diameter pipeline rubber flexible joints in the normal use of thermal expansion and contraction of some small offset is not yet significant, but encountered in special circumstances when the application of the pipeline, the pipeline expansion joint assembly position is not the same, the resulting effect is usually different. Pipeline manufacturing of rubber flexible joints use period is the same industry competition in the use of the period is very long. Generally, when the products are shipped from the factory, we will paint a layer of high-quality anti-corrosion and wear-resistant coating on the outside of the product, as a surface layer of protection to maintain the pipeline will not be damaged, because of the excellent corrosion and corrosion resistance rubber flexible joint products are mining pipelines and wastewater treatment pipelines, flue gas desulfurization pipelines and their granular materials. Slurry transport pipeline has been modified for many times.
