Product feature：

Our company has developed a new type of negative pressure resistant rubber joint in the rubber layer of the rubber joint pressurized, flexible steel plate, so that when the positive pressure rubber joint expansion, when the negative pressure rubber joint shrinkage sucking flat steel plate can well block the deformation of the rubber joint, to ensure that the shape meets the design requirements, this structure is suitable for use in corrosive media, Never settle, dig deeper, Zhongyuan valve fittings Reminder Dredava Friends can refer to these knowledge: The pressure ring part will not directly contact the medium to ensure the use of integrity, generally used in sewage treatment, waste water treatment, precious metal recovery.

Product advantage：

Negative pressure resistance rubber joint in the operation process of negative pressure resistance, high requirements, simple rubber is not resistant to negative pressure, for example, the pipe diameter is 0.1kg of negative pressure, the rubber tube body will suck flat, with the pipe external pressure is completely different, so, negative pressure inner diameter needs to increase negative pressure diversion tube, simply put, Negative pressure duct is to increase a carbon steel pipe in the inner diameter of the rubber shock absorber throat, but the inner diameter of the joint is smaller than the original inner diameter, with the negative pressure duct, the rubber shock absorber throat will not be sucked flat, so the vibration isolation of the original shock absorber throat, expansion effect will not be affected, only affected is the inner diameter of the joint slightly smaller.

Negative pressure resistance rubber joint application field：

The negative pressure resistant rubber joint has many superior performance in the use process, so it can be widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, freezing, health, water heating, fire protection, electric power and other basic engineering.
