Rubber soft connection can also be called: flexible rubber soft connection, rubber soft connection, soft joint, flexible rubber soft connection, rubber soft connection, shock absorber, shock absorber, etc. It is a highly elastic, highly airtight, medium and weather resistant pipe connection.
The soft rubber connection generally consists of an inner rubber layer, a fabric reinforcement layer (the reinforcement layer has multi-layer scratched nylon cord), a middle rubber layer, an outer rubber layer, and a reinforced metal ring or traveler at the end. After high temperature and high pressure, it forms a composite rubber tube composed of a metal flange or a loose sleeve of a parallel joint. This product utilizes the advantages of high elasticity, high gas performance, medium resistance, weather resistance and radiation resistance of rubber, which can reduce pipeline vibration and noise, and can compensate thermal expansion and contraction caused by temperature changes.
The rubber material used varies according to the medium, such as natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene rubber, silicone rubber, fluorine rubber, etc. Respectively have heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance and other functions.
Basic classification of soft rubber connections:
1. According to the performance, it is divided into three categories: general type, special type and heat-resistant type.
General type: suitable for transporting water at -15°C~80°C, acid solution or alkali solution with concentration below 10%.
Special category: suitable for special performance requirements, such as oil resistance, clogging resistance, ozone resistance, abrasion resistance or chemical corrosion resistance.
Heat resistance: suitable for conveying water with a temperature higher than 80°C.
2. According to the structure, it is divided into single sphere, double sphere, triple sphere, elbow sphere, wind pressure coil body, etc. Each form can be divided into concentric equal diameter, concentric different diameter, and eccentric diameter.
3. According to the shape, it can be divided into: concentric and same diameter, concentric and different diameter, eccentric and different diameter.
4. According to the connection form between the product and the pipeline, it can be divided into flange connection, threaded connection and clamp connection, threaded pipe flange connection, etc.
5. According to the working pressure: 0., 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa, 6.4MPa six levels.
