【Vacuum Negative Pressure】Rubber Joint for Vacuum

[Vacuum Negative Pressure] Negative pressure rubber joint:

There are two kinds of pressures on the rubber joint inside the pipeline. One is the very common positive pressure, which comes from the internal medium passing through the flow rate and exerted on the rubber joint. There is also a kind of pressure called negative pressure, which comes from the inside of the pipeline. , Due to various reasons, the internal air is sharply reduced, forming a state of suction, and 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 sucked flat. The installation of the negative pressure ring is generally selected before the assembly of the rubber joint. Since the negative pressure ring is as large as the interior, the negative pressure ring is generally installed before the rubber joint is assembled. Negative pressure rubber joint is manufactured by Huashunying Company using a new process of air blowing mold, which is composed of inner rubber layer, reinforcement layer, middle rubber layer and outer rubber layer. High pressure resistance, good elasticity, large displacement, good shock absorption and noise reduction, and easy installation. It can be widely used in water supply and drainage, HVAC, fire protection, compressors, papermaking, pharmaceuticals, ships, pumps, fans and other pipeline systems.

Technical parameters of negative pressure rubber  joint:

The single-ball negative pressure-resistant rubber joint produced by Huashunying Pipeline is a negative pressure device made of carbon steel or stainless steel. The following features are:

1. Really play the role of negative pressure and vacuum resistance.

2. Avoid the phenomenon that the rubber joint is flattened.

3. Whether it is an ordinary water pipeline or an acid-base pipeline, we can choose the matching material to produce the negative pressure device according to your medium.

4. It will not reduce the shock absorption, noise reduction, displacement and other properties of the rubber joint itself.

5. Disadvantages: The inner diameter is smaller than the inner diameter of the main pipe, which affects about 10% of the flow.
