Blind character, generally require the use of the emergency shut-off place. There are also two single combination, usually installed on the pipe piece, another piece to put together, need to use that time to come out with the use. Blind character generally requires strict cut off for the occasion, under certain circumstances, are generally used in more than DN50 pipeline, mainly because of the large diameter pipeline two blind flange to be inserted into a pipeline and pulled the sheet can be difficult to stay out of space, so usually are in the pipeline space, and then when you want to cut off one end of the board with one end of the belt loop of piping is breaking through is also clear. On the use of small diameter pipelines generally blind, because you can pull a small pipeline moving into a blind or can in two flange, blind but generally have a handle, otherwise often confuse the pass is off line . Blind character, you can switch the pipeline connectivity / off, and you can easily see that the pipeline connectivity / off state! Character is blind flange connection, a convenient switch it? Can not put the bolts are demolished, the media have had to put the tube inside and clean to work it? Why not cut off the valve it? Into and out of the device combustible gas , liquefied hydrocarbons, flammable liquids pipeline, at the boundary of the device should be located off valve and blind character in the production of antibiotic fermentation with some units vaccination station is blind character, which can ensure the effective cut pipe to prevent contamination; but the operation is indeed too much trouble, or more commonly used three-way diaphragm valve. 1 To cut off if the pipe is not blind character when needed off due to insufficient clearance is difficult to isolate the blind insertion operation 2. Blind character is usually set according to the technical and safety requirements needed in certain emergency shutdown of occasions. According to HG / T 20570.23-95 definitions, blind plate is mainly used for the production of complete separation of the media and prevent the shut-off valve closed lax affect production and even cause accidents. From the exterior, generally divided into blind character, flapper and pad ring (flapper and pad ring each other blind pass). Blind flange is the middle hole of the flange steel blind plate prices for sealed with duct plugs. Species form large sealing surface, with flat, convex, concave and convex surfaces, tongue and groove, ring joint face. Blind (blind disk) formal name is blind flange cover large diameter steel plate prices, but also called blind flange. The middle hole of the flange, sealed pipe plug for use. Species form large sealing surface, with flat, convex, concave and convex surfaces, tongue and groove, ring joint face. Blind plate for isolation from the cut action. Due to its good sealing performance, the need for a system completely isolated steel blind spot sales, generally as a reliable means of isolation. Blind is a solid round shank for systems under normal conditions in a state of isolation. The 8-word blind, shaped like eight words, one end is blind, the other side is the throttle ring, but with the same diameter as the pipe diameter, does not play a role in the throttle. 8 word blind, easy to use, you need isolation, using blind side, blind normal operation when needed, using the throttle ring side, but can also be used to install the pipeline to fill the gap blind plate. Another significant feature is the identification, easy recognizable installation status.
