Abstract
The utility model provides a screw thread formula pipe connections head. Its connector is connected through taper pipe thread and cylindrical thread with sealed head, and its inside and outside partial junction all is equipped with the sealing washer. The taper pipe thread makes to screw between connector and the sealed head and to seal, cylindrical thread between to connector and sealed head the screw in play guiding effect, sealing washer on two fitting surfaces also plays sealed effect, the utility model discloses since it is rational in infrastructure, effectual leakproofness and the reliability that has improved screw thread formula pipe connections head.
Description
Technical field
This utility model relates to pipe joint field, particularly to a kind of thread type pipe connector.
Background technology
Pipeline is in industry, agricultural and urban construction, it is widely used, in order to save pipeline, the most wide variety of casting copper sleeve, plastic pipe joint is first-class a variety of, mostly uses cutting ferrule or card crimp head to connect, its installation or removal are the most loaded down with trivial details, laborious, and stable connection performance is low, sealing is poor, it is impossible to meet the needs of people.
Taper pipe thread also have one address cry: dry sealing thread, namely need not any implant, directly screw the most salable.It has the main former of sealing characteristics should 2 points: 1. due to tapering, this screw thread with as taper thread or cylindrical thread when coordinating, there is " self-tightening effect "；2. its special thread form design has the characteristic (unlike common metric thread, at the bottom of its crest and tooth between be to have the crest in gap flat and circle at the bottom of tooth) of " fitting like a glove ".
Summary of the invention
The deficiency complicated in order to solve existing pipe connector structure, this utility model provides the pipe connector of a kind of simple in construction.
This utility model solves the technical scheme is that thread type pipe connector of its technical problem and includes union joint and seal head, described union joint and seal head are hollow form, taper pipe thread and cylindrical thread all it is provided with on described seal head and union joint, and taper pipe thread is connected with cylindrical thread, described seal head is provided with sealing ring (A) with the outer junction of union joint, and described seal head is provided with sealing ring (B) with the interior junction of union joint.
All being provided with taper pipe thread on union joint and seal head, taper pipe thread makes to screw between union joint and seal head salable, and cylindrical thread plays guide function to screwing between union joint and seal head；Sealing ring on two cooperation faces also plays sealing function.
The beneficial effects of the utility model are: this utility model, due to rational in infrastructure, effectively raises sealing and the reliability of thread type pipe connector.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
1. union joint in figure, 2. seal head, 3. taper pipe thread, 4. sealing ring (A), 5. sealing ring (B), 6. cylindrical thread.
Detailed description of the invention
As shown in Figure 1, thread type pipe connector includes union joint 1 and seal head 2, described union joint 1 and seal head 2 are hollow form, described seal head 2 is all provided with taper pipe thread 3 and cylindrical thread 6 on union joint 1, and taper pipe thread 3 is connected with cylindrical thread 6, described seal head 2 is provided with sealing ring (A) 4 with the outer junction of union joint 1, and described seal head 2 is provided with sealing ring (B) 5 with the interior junction of union joint 1.
