Abstract
The utility model provides a plug of coupling, the one end of plug is the hexagon column body, the cylinder of centre for being equipped with the external screw thread of this plug, and the other end of this plug is the cone that the radius is gradually little, the coupling with the plug phase -match. The utility model has the advantages of one end at the plug is provided with the cone, and this cone blocks up the minor diameter inner chamber at the coupling latter half, can play fine sealed effect, when using, only need with the plug pass through screw thread screw in coupling can, need not use the sealing washer, it is extremely convenient consequently not only to use, and can reduce the combination cost to stop the sealing washer and cause secondary pollution to water, when putting into production, the plug can one shot forming, can reduction in production cost.
Description
Technical field
The utility model is paddled warm field, refers in particular to a kind of plug of pipe joint.
Background technique
Plug is pipe fitting conventional during water heating system is installed, and it is mainly used in the end blocking pipeline, and plays the effect of sealing, to prevent the leakage of pipe end.At present when using plug, being all be wound around raw meal belt in the above or overlap O RunddichtringO on band ear plug usually, reaching the effect of sealing with this.But adopt winding raw meal belt to there is following defect: waste time and energy during use, and sealing effect to be not good, once suppress examination, often to there will be weeping; O RunddichtringO is adopted to there is following defect: O RunddichtringO usually can be caused because overexerting during use to be shifted and be out of shape; thus do not reach the effect of sealing leak-stopping; and when suppressing examination; because hydraulic pressure is larger; usually O RunddichtringO can be ejected original position; make O RunddichtringO cannot be spacing, and then cause pipeline to leak air, leak.
Simultaneously, the applying date is 2014.07.08, application number be 201420373380.9 Chinese utility model patent disclose a kind of plug and water heating pipe fittings, this plug is provided with seal groove, during installation, seal ring is fixed by sealing groove, and can prevent seal ring from producing displacement, therefore sealing effect is ideal.But this plug has following defect: 1, needing combines plug and seal ring uses, not only combine cost higher, and seal ring is quality of rubber materials, in use still cannot avoid the generation of phenomenons such as being out of shape, come off; 2, plug must separate with seal ring and produces, cannot once-through, this considerably increases cost of production; Although 3, seal ring can play good seal action, be easy to cause secondary pollution to water.
Summary of the invention
The technical problems to be solved in the utility model, is the plug providing a kind of pipe joint.
The utility model is achieved in that a kind of plug of pipe joint, and one end of described plug is hexagonal cylindrical body, and the centre of this plug is for being provided with externally threaded cylindrical body, and the other end of this plug is the cone that radius is gradually little; Described pipe joint and described plug match.
Further, the inner chamber of described pipe joint is shoulder hole structure, and this pipe joint is provided with internal thread on the major diameter inner chamber of front half part, and described pipe joint and the cylindrical body in the middle of plug are mated by internal thread and outside thread and be connected; Described cone is jammed in the minor diameter inner chamber of described pipe joint latter half part.
Further, described plug is provided with a hexagonal hole at the center of hexagonal cylindrical body one end.
Further, described cone replaces with round platform.
The utility model has the advantage of: 1, one end of plug is provided with cone, this cone is blocked in the minor diameter inner chamber of pipe joint latter half part, can play good seal action; 2, in use, only needing by plug by being threaded into pipe joint, not needing to use seal ring, it is extremely convenient therefore not only to use, and in using process, plug is not fragile yet, long service life, and can reduce combination cost; 3, when producing, this plug can once-through, and it is extremely convenient therefore to produce, and can reduce cost of production; 4, secondary pollution can not be caused to the water in pipe joint, the quality of water can be improved.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is the sectional view of the utility model embodiment.
Fig. 2 is the plan view of the utility model embodiment.
Embodiment
Refer to shown in Fig. 1 and Fig. 2, a kind of plug 2 of pipe joint 1, one end of described plug 2 is hexagonal cylindrical body 21, and the centre of this plug 2 is for being provided with the cylindrical body 22 of outside thread 221, and the other end of this plug 2 is the cone (not shown) that radius is gradually little; Described pipe joint 1 mates with described plug 2 and is connected.
The inner chamber of described pipe joint 1 is shoulder hole structure, and this pipe joint 1 is provided with internal thread 111 on the major diameter inner chamber 11 of front half part, and described pipe joint 1 and the cylindrical body 22 in the middle of plug 2 are mated by internal thread 111 and outside thread 221 and be connected; Described cone is jammed in the minor diameter inner chamber 12 of described pipe joint 1 latter half part.
Described plug 2 is provided with a hexagonal hole 3 at the center of hexagonal cylindrical body 21 one end, like this, when inner hexagon spanner can also be adopted to install plug 2 when lacking common wrench.
In order to save material, described cone replaces with round platform 23.
Working principle of the present utility model is: when mounted, adopts spanner by plug 2 spinning in pipe joint 1, and makes the cone of this plug 2 front end (or round platform 23) be jammed in the minor diameter inner chamber 12 of pipe joint 1 latter half part, to reach the effect of sealing.
In sum, the utility model has the following advantages: 1, one end of plug is provided with cone, and this cone is blocked in the minor diameter inner chamber of pipe joint latter half part, can play good seal action; 2, in use, only needing by plug by being threaded into pipe joint, not needing to use seal ring, it is extremely convenient therefore not only to use, and in using process, plug is not fragile yet, long service life, and can reduce combination cost; 3, when producing, this plug can once-through, and it is extremely convenient therefore to produce, and can reduce cost of production; 4, secondary pollution can not be caused to the water in pipe joint, the quality of water can be improved.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, include in scope of patent protection of the present utility model.
