Detailed
Direct fast connection-peg of quick installation, simple dexterity, save space;Type diversity, satisfy the need of any pneumatic tube;Even after the installation, also can be arbitrary to plastic pipe body;Release ring USES the circular design, remove more convenient save Labour;All the taper pipe threads precoating ptfe leakproof gum,Good sealing performance.
The utility model relates to a quick joint structure for metal hose, belonging to the field of pipe fitting technology, which is used to solve the problem of large volume and high cost of metal hose joint.The structure is composed of a quick joint and a metal hose combination. The quick joint includes a first pipe, a second pipe, a connection sleeve, a non-standard stainless steel joint opening sleeve and a locking nut. The first pipe of the hydraulic pipe joint is connected with one end of the connection sleeve with a threaded connection, and the other end of the connection sleeve is provided with a plug pipe.Compression clamps are uniformly distributed on the open card sleeve. A locking cone is provided on the compression clamps of the transition joint. The inner hole of the locking nut is provided with a circular cone matching with the locking cone.The outer diameter of the second pipe matches the inner diameter of the inserted pipe and the inner diameter of the open bayonet. The locking nut is connected with the thread of the inserted pipe.The utility model has the advantages of simple structure, compact appearance, cost, firm connection, high bearing capacity, durable anti-detaching, no looseness, no leakage, convenient maintenance and replacement, etc.Can be widely used in petrochemical, metallurgy, heating and other fields of metal hose and process equipment connection pipe technology.
Technical field
The utility model relates to a quick joint structure for connecting metal hoses, belonging to the technical field of pipe fitting.
Technical background
[0002] of the metal hose as connection piping process equipment or equipment technology, is used to supplement or absorbed by medium pressure, temperature changes and piping system vibration physical variables such as the elasticity of the device. The metal hose and connection process, process equipment or equipment with GB/T 8615-2002 the corrugated metal hose with the alloy steel and stainless steel fittings, or related flange standard parts.These standard parts are usually connected by thread fastening.In special cases, pull rod quick connector or quick change connector connection.In the above connection mode, fastener connection is not only time-consuming and laborious, non-standard stainless steel quick insert joint and the size of the joint is larger, the use is limited by the space position, at the same time, fastening seal has become the key technology to realize the connection.In the connection mode of the quick connection or quick change connection, the quick connection type of the pull rod, although the connection mode is fast, but because of the large size of the pull rod, the hose connection needs a larger space position, which brings greater economic waste to the dense process pipeline design.The quick change joint connection, although the connection is fast, but the manufacturing cost is larger, the general 1/2 "hose quick change joint is 2-3 times higher than the hose price.
