Description
Technical field
The utility model is related to pipeline equipment technical fields, more particularly to a kind of casing joint.
Background technology
Pipe fitting is the fastening means between pipeline and pipeline, is the tie point that can be dismounted between element and pipeline.
Indispensable key player is acted as in pipe fitting, it is one of two main composition parts of hydraulic pipeline.Pipe fitting is used for
Instrument isoline connects, and type of attachment has socket weld or threaded connection.It is mainly used for small-bore low-pressure line, it is frequent for needing
The position of assembly and disassembly or as using the final adjustment of threaded fitting pipeline to be used.Structure type preferably uses metal covering contact sealing
Structure, the structure type of gasket seal is commonly used in conveying on the general pipeline such as water, oil, air, using malleable cast iron material system
It makes.In addition, requirement and price etc. are also the factor considered when selecting.
Pipe fitting has numerous types, common pipe fitting to can be generally divided into two kinds of hard pipe joint and hose coupling.
If divided according to the connection type of pipe fitting and pipeline, hard pipe joint has three kinds of flared type, bite type and welded type, and hose connects
Head is mainly then attaching type rubber hose coupling.
In heating and ventilating pipeline, the connection type of pipe fitting is also different, and pipeline screw terminal is using connection screw thread.Closely-pitched
The sealing effect of screw thread is very good, is often used in high-pressure system, but it needs to be directed to using bonded washer or O-ring
The closing work of end face, can also use copper washer sometimes, it is relatively suitble in the thicker pipeline of connection tube wall, composition
Mainly there is fittings body in part, takes over and nut.When in use, fittings body is embedded in target, is used cooperatively pad said before
End face seal fittings body and is used rubber seal between taking over by circle, can also the mode of ball face sealing be used to carry out sometimes.
Since pipe fitting belongs to dismountable connecting element, normal stable connection, leakproofness be strong, size meeting for it
Rationally, except the requirement that the pressure loss is small, processing performance is good etc., it is necessary to meet that dismounting is convenient to be required.Therefore, should not
That slight pipe fitting one by one is looked down upon, because only that its presence can just support the presence of entire hydraulic system.
However traditional pipe fitting is in external branched pipe, branched pipe can not freely conversion angle, branched pipe
Position directly when pipe fitting manufactures just it has been determined that therefore, cause pipe fitting very complicated in installation and maintenance process, repair
It even needs that angular adjustment could be carried out to the branched pipe of pipe fitting after dismantling other components in the process, can bring unnecessary
Economic loss.To solve this technical problem, the utility model will be improved design on the basis of conventional pipe joint.
