In pipe work, flanges are installed on connected pipes.
In pipe work, flanges are installed on connected pipes. Low-pressure pipes can be used with wire-connected flanges, and welded flanges are used for pressures above 4kg. Add a sealing ring between the two flanges, and then fix it with bolts and nuts. Flanges with different pressure levels have different thicknesses, so the bolts used are also different. Pumps and valves, when connected to the pipeline, the parts of these equipment and equipment are also made into corresponding flange shapes, also known as flange connections. What role does the flange play in the rubber soft joint?
The sealing of natural rubber joints is also very closely related to the flange plate. In order to better avoid water leakage when carrying out flange connection, it is generally necessary to press it together with all efforts. If the quality is not very good, it is very likely that there will be problems before the flange plate is applied. Therefore, for natural rubber joints, the selection of rubber soft joint flange is very critical. Rubber soft joints are divided into three types: loose sleeve flange type, fixed clamp check valve and external thread type according to the interface mode. So in the application of the clamp check valve connection case we are also how to choose?
Under normal conditions, over-diameter disc valves are required. The special design scheme is due to the fact that the standard flange plate is too consumed. Under normal circumstances, the working pressure of over-diameter pipeline materials is relatively thin flange plate. However, the application of rubber soft joints and wafer butterfly valves exceeding 16KG must be made of special flange plates for disc valves or butt welding flanges. The socket of such flange plates is small, and the protruding surface is generally large under sealing conditions. In that case, under the sealing conditions of wafer butterfly valves and rubber soft joints, the total area touched is very large, which has very good sealing properties, ensuring that the wafer butterfly valves and rubber soft joints can have very good sealing properties even if there are installation errors.
