Negative pressure rubber joint

Negative pressure rubber joints are often used for cold water, hot water, compressed air, natural gas and other media. With unique design, novel structure and good sealing performance, it solves the problem of pipe bursting and damage to pipe connection equipment caused by thermal expansion and contraction. This improves the service life of the pipeline and the protection of the equipment.

Product advantages

The negative pressure comes from the inside of the pipeline. Due to various reasons, the internal air is drastically reduced, forming a state of suction. The pipeline can naturally withstand it. At this time, it depends on whether the rubber joint can completely resist it. If it cannot resist the negative pressure, the rubber joint will be affected. Suck flat. The installation of the negative pressure ring is generally selected before the process of assembling the rubber joint. Since the negative pressure ring is as large as the inside, the negative pressure ring is generally installed before the rubber joint is assembled. Negative pressure rubber joint is manufactured by Liangzhong Company using the new process of air blowing mold. It is a product composed of inner rubber layer, reinforcement layer, middle rubber layer, outer rubber layer and composite ball and loose forged mild steel flange. Features such as high pressure, good elasticity, large displacement, good shock and noise reduction effect, and convenient installation. It can be widely used in pipeline systems such as water supply and drainage, HVAC, fire protection, compressors, papermaking, pharmaceuticals, ships, water pumps, fans, etc.


Features

Installing a negative pressure ring is an indispensable job for rubber joints, because the positive pressure of rubber joints can reach very high, but the negative pressure will fall on the contrary. For the installation of negative pressure rings, the rubber joints are practical Improve sex. The installation of the negative pressure ring is generally selected before assembling the rubber joint. Since the negative pressure ring is as large as the inside, it is very troublesome to install the negative pressure ring after the rubber joint is assembled.

1. Small size, light weight, good flexibility, easy installation and maintenance.

2. It can produce lateral, axial and angular displacement during installation, and is not restricted by the non-concentricity of the pipeline and the non-parallel flanges.

3. It can reduce the noise transmitted by the structure while working, and has a strong shock absorption capacity.
