5. Due to the good comprehensive performance of rubber joints, it is widely used in basic engineering such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, etc. It is especially suitable for large vibration and cold Pipes with frequent thermal changes.
Product features of DN150 single ball rubber joint:
1. KXT type DN150 single ball rubber joint has high internal density, can withstand higher pressure, and has good elastic deformation effect. This product is manufactured by the new process of air blowing molds. It is a product composed of inner rubber layer, reinforcement layer, middle rubber layer, outer rubber layer and composite ball and loose forged low-carbon steel flange. It has high pressure resistance and good elasticity. , Large displacement, good shock and noise reduction effect, convenient installation and other characteristics. It can be widely used in pipeline systems such as water supply and drainage, HVAC, fire fighting, compressors, papermaking, pharmaceuticals, ships, water pumps, fans, etc.
2. The rubber joint is composed of fabric-reinforced rubber parts and loose metal flanges, which are used for pipe noise reduction, shock absorption, and displacement compensation joints. It is a pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. Strictly follow international standards and raw material quality requirements to prevent cutting corners. Environmental protection standards mean that product raw materials require not only new materials, but also environmentally-friendly new materials.
DN150 single ball rubber joint rubber ball material:
The rubber soft joint sphere is composed of an inner rubber layer, a reinforced layer with a multi-layer scraped nylon cord fabric, and an outer rubber layer composite rubber tube. According to different media, the rubber materials used are different, such as natural rubber, styrene butadiene rubber, butyl rubber, nitrile rubber, EPDM, neoprene, silicone rubber, fluorine rubber, and so on. Respectively have the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, abrasion resistance, and oil resistance.
Instructions for use of DN150 single ball rubber joint:
1. When using this product for high-level water supply, the pipe must have a fixed bracket, otherwise the product should be installed with anti-pull support device. The force of the fixed support or bracket must be greater than the axial force, otherwise the anti-pull support device should also be installed.
2. You can choose to use the working pressure according to your own pipeline: 0.25mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa, 4.0Mpa flexible rubber joints, and the connection dimensions refer to the "Flange Size Table".
Material of each part of DN150 single ball rubber joint:
1. Inner rubber: NR, NBR, EPDM (you can choose high temperature resistance, acid and alkali resistance, oil resistance, abrasion resistance, etc.)
2. Outer layer glue: NR, NBR, EPDM (you can choose high temperature resistance, acid and alkali resistance, oil resistance, abrasion resistance, etc.)
3. Main frame: nylon cord (the same material as the tire inside)
4. Pressurized ring: high-pressure steel wire rope
5. Flange: carbon steel Q235A (forged) surface sprayed with anti-rust paint, stainless steel 301, stainless steel 316L, PVC material)
DN150 single ball rubber joint chooses different rubbers to play different roles:
1. Natural rubber NR (over water, below 80 degrees)
2. EPDM (high temperature below 150 degrees, acid and alkali resistance, corrosion resistance, power plant desulfurization, lime slurry, gas, etc.)
3. Nitrile rubber NBR (oil resistance, including hydraulic oil, aviation kerosene and other oils, high temperature resistance below 150 degrees)
4. Wear-resistant rubber TZ (wear-resistant, generally used in the mineral industry, granular medium conveying pipelines)
5. Special rubber (emulsion, sulfuric acid and other special media)
Introduction of rubber joints:
Rubber joints are shock-absorbing joints installed at the inlet and outlet of the water pump, which can effectively ensure the service life of the water pump, and can also absorb the noise and vibration generated by the water pump when it is working. It can be installed on various vibration pipelines, and the central air-conditioning host Imported and exported, etc., the service life is as long as 5 years, and the service life of special materials is 3 years, and the use cost is low. It is the first product for sound insulation and noise reduction in many pump rooms.
Installation of rubber joints:
1. Please use the following standards (special flange for wafer type butterfly valve) when selecting pipeline flat welding flange. The sealing surface of rubber joint and the sealing surface of soft sealing butterfly valve need to be sealed with special flange for butterfly valve to achieve the best sealing effect.
2. The inner diameter of the connecting part of the water pipe mouth must be the same as the inner diameter of the rubber shockproof joint.
3. The flange contact surface of the flange connected to the water pipe port must be smooth and flat in order to ensure a large sealing space. (As shown in the figure below), when the rubber anti-vibration joint is not tightly connected with the contact surface of the water pipe mouth, noise, insufficient pressure, and water leakage will occur.
DN150 single ball rubber joint remarks requirements:
1. Special requirements can be made according to user drawings, flange standard adopts GB/T9115.1-2000, optional (GB, JB, HG, CB, ANSI, DIN, BSEN, NF, EN, JIS, ISO, etc.) method Blue standard production. The rubber ball can be made of natural rubber, EPDM rubber, neoprene rubber, butyl rubber, nitrile rubber, fluorine rubber, etc.
2. When products above DN200 are used for suspended water supply, the pipeline must have a fixed support or a fixed bracket, otherwise the product should be equipped with an anti-pull device.
3. If the user uses rubber joints, the corresponding flange should be a valve flange or a flange that conforms to GB/T9115.1-2000.
