Fan coil threaded rubber joints are threaded joints of rubber joints. The middle double ball part material can be made of ordinary natural rubber material, EPDM rubber material, nitrile oil resistant rubber material. The threaded ends of the two ends are connected, and the pressure grade can be divided into 1.0 MPa, 1.6 MPa, 2.5 MPa, and the like.
Simple structure, convenient installation, good shock absorption effect, etc.
The triangular threaded rubber joint is composed of a rubber ball and two metal parallel joints. The threaded soft joint is mainly used for the connection of steel pipes, copper pipes and high pressure. The thread of the welded steel pipe is mostly operated by a threading machine. For threading accuracy and surface roughness, we must add it to a high-pressure pipe lathe.
The damage of the triangular threaded rubber joint is smaller than that of other rubber joints, but the reason for his reduction in damage comes from his model size. The threaded rubber joint is small in size, and the threaded rubber joint can only be made up to DN80 at the time of manufacture, so in terms of pressure resistance, the threaded rubber joint can completely override the pressure inside the pipe, which causes the threaded rubber joint to burst and The situation of sucking is much less.
The connection of the threaded rubber joint with the pump and the valve is especially suitable for pipes with large vibration and frequent changes in heat and cold. The product is suitable for medium: seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, refined oil, air, gas, steam and granular powder. Fan coil threaded rubber joints have good comprehensive performance, mainly used for lifting and conveying raw water and sewage, water supply and cooling circulating water of thermal power plants, metallurgical industry, condensate, pipeline transportation of chemical substances in chemical industry, petrochemical industry Cooling, dilution and flexible connections between pipelines in other industries.
1 Triangle threaded rubber soft joints must be selected according to the working pressure, connection mode, medium and compensation amount of the pipeline, and the number is selected according to the requirements of reducing the displacement.
2 When installing the pipeline to generate instantaneous pressure and greater than the working pressure, use a joint higher than the working pressure. (For example, when the pressure at the start of the pipeline is greater than 1.0MPA, the joint with a working capacity of 1.6mpa should be used. When the instantaneous pressure is greater than 1.6Mpa, the joint of 2.5Mpa should be used)
3 When the medium of the triangular thread rubber joint pipe is acid, alkali, oil, high temperature and other special materials, the joint should be selected above the working pressure of the pipeline.
4 Normally applicable medium is ordinary water with temperature of 0-60 °c. For special medium such as oil, acid and alkali, high temperature and other corrosive and hard texture, the corresponding soft rubber connection of special resistant material should be used. Blind string or universal.
