China Jingning Dn30-Dn3000 Flange Rubber Flexible Connector Expansion Joint
Rubber flexible connector can also be called: flexible rubber joint, rubber soft joint, soft joint, flexible rubber joint, etc. Rubber flexible connector is a pipe connector with high elasticity, high air tightness, medium resistance and weather resistance. Rubber flexible connector is a kind of composite rubber pipe which is composed of inner rubber layer, fabric reinforcement layer (the reinforcement layer has multi-layer scraped nylon cord), middle rubber layer, outer rubber layer, end reinforced metal ring or steel ring, and loose combination with metal flange or parallel joint after high temperature and high pressure vulcanization. The rubber flexible connector makes use of the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance. Rubber flexible connector can reduce the vibration and noise of the pipeline, and compensate the thermal expansion and cold contraction caused by temperature change.
Performance characteristics of rubber flexible connector
1. The decompression effect of rubber flexible connector is reliable, and the outlet pressure is not affected by the inlet pressure and flow rate. It can reduce both dynamic pressure and static pressure, and keep the set outlet pressure constant.
2. The rubber flexible connector is easy to adjust and operate. Just adjust the adjusting screw of the pilot rubber joint to obtain accurate and stable outlet pressure.
3. The rubber flexible connector has good energy saving effect. The rubber joint body adopts full channel streamline DC design, with small pressure loss, large flow, small volume and light weight.
4. The rubber flexible connector has a long service life, and the important parts are made of special materials, so there is no need for maintenance.

Note: 1. The special requirements of rubber flexible connector can be customized according to user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of rubber flexible connector can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the rubber flexible connectorabove DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the rubber flexible connector shall be installed with anti falling device.
