Description
Technical field
The utility model belongs to pipe joint technical field, relates to the rapid pipe joint that a kind of heavy aerofoil profile is threaded.
Background technique
The fluid hydraulic quick coupling of the existing type that is threaded, when connecting, most employing spanner blocks outer ring hexagonal and tightens, and utilizes the screw thread on outer ring mutually to spin, and promotes docking of housing spool and plug spool, open the valve of joint, form fluid passage, if but this when having a residual voltage in pipeline, can be more painstaking when tightening, even cannot turn outer ring, just cause joint normally to connect.
Model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, is the rapid pipe joint that fluid circuit provides a kind of heavy aerofoil profile to be threaded.
The technical solution of the utility model:
The rapid pipe joint that a kind of heavy aerofoil profile is threaded, it comprises housing, outer ring, plug, spring and seal arrangement, housing and outer ring are slidably connected and spacing by the outer ring ring washer on housing, housing and plug inner chamber is spacing is slidably connected, the internal thread of outer ring and the outside thread of plug are threaded connection, and outer ring is provided with two all-wing aircrafts.
Housing spool and housing valve pocket is provided with in the inner chamber of housing, housing spool is fixedly connected with by screw thread with the interior step in housing cavity, housing valve pocket be slidably connected between housing cavity with housing spool and by housing valve pocket spring with in housing cavity in step end face be connected.
Be provided with plug spool and plug valve core spring in the inner chamber of plug, plug head is provided with cone shape hole and is connected with the spool end of plug spool is spacing, and the opposite side end face of plug spool is connected with the interior step of plug rear end is spacing by plug valve core spring.
The opposite side end face of plug spool is connected with plug valve core spring pad by plug valve core spring, and plug valve core spring pad passing hole ring washer is connected with in plug rear end, step is spacing.
After outer ring and plug are threaded connection, plug spool and plug back down by housing spool, and are communicated with the fluid bore of housing spool and jointly form fluid passage.
The be threaded rapid pipe joint of type of the utility model increases by two all-wing aircrafts on outer ring, when plug is connected with housing, and rotatable two all-wing aircrafts, reach labour-saving object, when there is residual voltage in pipeline, then available hammer knocks two all-wing aircrafts, overcome pressure in pipeline, realize connecting.The heavy joint that this kind of application can connect under stress, overflow is little or do not have overflow, has the application of comparatively wide model, especially needs the application of the high flow capacity joint connected under stress.
