Describe
Negative pressure rubber joint
Negative pressure rubber joints have many names such as: shock absorbers, rubber shock absorbers, etc. The addition of a negative pressure ring inside the rubber joint can improve the safety of the rubber joint. Negative pressure rubber joints are often used in cold water, hot water, compressed air, natural gas and other media. It solves the problem of pipe bursting and damage to pipe connection equipment caused by thermal expansion and contraction with unique design, novel structure and good sealing performance. Improve the life cycle of the pipeline and the protection of the equipment.
 
[product alias]: flexible rubber joint, rubber soft joint
[product pressure]: 0.6MPa-2.5MPa
[product specifications]: [DN32mm-DN4000mm]
[Product Certification]: ISO9001-2008
[Scope of application]: [acid, alkali, corrosion, oil, hot water, cold water, compressed air, compressed natural gas, etc.]
[Working temperature]: -40 degrees to 80 degrees (can also process high temperature rubber joints)
[product material]: the sphere is natural rubber, the flange is carbon steel, stainless steel
 
Features
The negative pressure comes from the inside of the pipeline. Due to various reasons, the internal air is drastically reduced, and the suction is formed. The pipeline can naturally withstand. At this time, the rubber joint can be completely resisted. If it can not resist the negative pressure, the rubber joint will be Sucking. The installation of the negative pressure ring is generally selected before the assembly of the rubber joint process. Since the negative pressure ring is as large as the inside, the negative pressure ring is generally installed before assembling the rubber joint. The negative pressure rubber joint is made by Xinli Company using the new technology of air blow mold, which is composed of inner rubber layer, reinforcement layer, medium rubber layer and outer rubber layer composite ball and loose sleeve forged low carbon steel flange. High pressure, good elasticity, large displacement, good shock absorption and noise reduction, easy installation and so on. It can be widely used in water supply and drainage, HVAC, fire protection, compressors, paper, pharmaceutical, ship, water pump, fan and other pipeline systems.
 
The installation of the negative pressure ring is an indispensable work for the rubber joint, because the positive pressure of the rubber joint can be very high, but the negative pressure will be reversed. For the installation of the negative pressure ring, the utility of the rubber joint is practical. Improve one level. The installation of the negative pressure ring is generally selected before the rubber joint is assembled. Since the negative pressure ring is as large as the inside, it is very troublesome to install the negative pressure ring after assembling the rubber joint.
1. Small size, light weight, good elasticity, convenient installation and maintenance.
2. Horizontal, axial and angular displacement can be generated during installation, which is not restricted by the difference of the pipe and the flange is not parallel.
3. It can reduce the structure transmission noise during work and has strong shock absorption capability.
