Introduction: Rubber joint. The standard CJ / t208-2005 of Ministry of water resources is the document that specifies the rubber joint. The article has clear regulations on the product, indicating that the product should meet the following requirements. Point: the extrusion process of the national standard rubber joint is to make the rubber material advance continuously through the rotation of the screw

Rubber joint The standard CJ / t208-2005 of the Ministry of water resources is a document that specifies the rubber joint, which indicates that the product should meet the following requirements. Point: the extrusion process of the national standard rubber joint is that the rubber material is continuously pushed forward by the rotation of the screw rod, and various semi-finished products with required shapes can be produced with the help of the mouth shape. The point of extrusion process is that the quality of semi-finished products is uniform and dense, and it is easy to change the specification and section shape of semi-finished products.
The extrusion process of national standard rubber joint in the extruder is divided into two parts: one is extrusion system, which is used to push rubber compound; the other is mouth type system, which is used to shape the rubber compound and make it into definite section shape. Therefore, the rubber layer of the national standard rubber joint is usually more than ten layers in the pressing process, and the rubber joint has a compact structure and a high degree of pressure resistance.
The successful rubber joint is between the unqualified products and the national standard products. Illegal merchants often reduce the cost of rubber joints by reducing the number of layers of rubber joint balls. Use non-standard products to replace national standard products. Non standard products in the use process due to the arc surface pressure bearing layer rubber layer is insufficient, the strength is reduced, in the use process, it is easy to cause pipe network burst due to insufficient pressure bearing.
In terms of appearance, there are not many differences between the imported rubber joint and the national standard rubber flexible connection produced in China, but the flange is higher in anti-corrosion and matching degree than the domestic standard. In terms of cost performance, import Rubber flexible joint It can't be compared with that in China. From the function analysis, no matter what kind of standard rubber joint is to play the role of noise reduction, noise reduction and vibration reduction.
It is worth mentioning that the middle flange of the German standard flange is a flange with diameter, which is mainly used to stabilize the rubber soft connection. The flange diameter of the flange is inclined, which can contact the surface of the rubber soft joint, protect the rubber ball from being damaged by the edge of the flange, which is conducive to extending the service life of the rubber flexible connection, especially in the connection of large diameter pipes.
