Use rubber joints with waterproof sleeves

Updated: 2014-04-06 11:43 Source: Unknown Hits:
In addition to the raw rubber, the rubber joint's usual joint waterproofing sleeve system includes rubber vulcanization. In addition to the raw rubber, the rubber joint system includes a vulcanization system (vulcanizing agent, accelerator, active agent, etc.) that causes the crosslinking reaction of the rubber molecular chain. Anti-scorching agent, etc.); Reinforcing and filling systems (reinforcing agents, fillers) to improve the mechanical strength of the product; Protective systems (various types of antioxidants) to protect rubber products, prevent aging, and extend service life; improve rubber processing Performance plasticizing system (various types of plasticizers). Currently, styrene-butadiene rubber, isoprene rubber, butyl propylene rubber, butyl rubber, etc. are used in emulsion polymerization.
Vulcanization is the last stage of the finished rubber joint. Part of the quality of the rubber joint is determined by vulcanization. Because rubber has high abrasion resistance, it is also suitable for low temperature transportation of granular and powdery and vapor in all industries. Because rubber is a poorly conductive material, it is also an ideal environmentally friendly product to reduce vibration and noise transmission. The design of the product has a smooth inner wall. After actual testing, it has no effect on the flow rate and flow of the medium, and it will never rust. , Basically can be exempted from maintenance during the effective operation period.
Acid and alkali resistant flexible rubber joints are made of ethylene-propylene rubber based on the copolymerization of mono-olefin ethylene and propylene into two-component ethylene-propylene rubber; ethylene, propylene and a small amount of non-conjugated diene are used as monomers to obtain three-component ethylene-propylene. rubber.

Rubber joints are connected with waterproof casing pumps, valves, fire fighting equipment, pipes that are shocked to a large extent, and pipes that change frequently in hot and cold. They can absorb the thermal expansion and contraction of pipes and the shock caused by work, thereby effectively protecting pipes and equipment. Function, prolong the service life, and have good comprehensive functions. 6. Flexible rubber joints should be located near the pump side when the pump is used at the inlet and outlet of the pump, and a metal reducer should be installed between the pump and the reducer. At the large caliber. According to the connection method, it can be divided into loose flange type, fixed flange type and thread type. According to the structure, it can be divided into 5 types: single sphere, double sphere, reducer, curved sphere and wind pressure coil. For rubber joints in pipes, what to do if the displacement of the pipe is greater than the compensation amount of the rubber joints.
The sphere of the acid and alkali resistant flexible rubber joint is composed of a rubber tube with an inner rubber layer, a reinforced layer with multiple scraped nylon cord fabrics, and an outer rubber layer. The central skeleton layer connects the inner and outer rubber layers well, and avoids the broken chain inside the rubber, which can well prevent the occurrence of cracks and leaks in the rubber joint.
The European Union has published a white paper. Once EU legislation prohibits or restricts the use of these materials, waterproof casings will have a greater impact on the export of China's rubber products. We must find alternatives as soon as possible and adjust the production formula in time to meet the challenges we face. 8. For high-level water supply or suspended water supply, the pipeline shall be fixed on a hanger, bracket or anchorage, and the joint shall not bear the weight and axial force of the pipeline, otherwise the joint shall be equipped with anti-pulling device. Rigid waterproof sleeves are used in structures (buildings) where pipelines passing through walls do not accept pipeline vibration and expansion and contraction. Different rubber products have different processing techniques. When the pipeline medium is resistant to acid, alkali, oil, high temperature and other special materials, a joint with a gear higher than the obligatory pressure of the pipeline should be selected.

In the process of rubber joint reproduction, there will be N-nitrosamine rubber additives, and this additive is a carcinogen, so how to solve this carcinogen. This product can reduce vibration and noise, and can compensate for thermal expansion and contraction caused by temperature change. It is widely used in various pipeline systems.

4. The mounting bolts should be tightened gradually and symmetrically to prevent local leakage. The waterproof sleeve thus improves the ability of the rubber joint to resist pressure, high temperature and fatigue. Steel pipe sleeve rubber joints are known as clamp-type rubber joints. The two mouths of the clamp-type rubber joints are set separately on the pipeline to be connected, and the rubber joint is fixedly connected to the pipeline via the clamp; Just fine.
