Abstract
The utility model discloses an external screw thread plug that is used for the stifled water of screwed joint in the pipeline, including inside and outside hexagonal end cap and end cap body, inside and outside hexagonal end cap and this body coupling of end cap, its characteristics be for there being the external screw thread in this external system of end cap, be equipped with the trapezoidal salient base that extends forward at the front end of end cap body, the diameter of trapezoidal salient base is less than the diameter of end cap body, and the point diameter of trapezoidal salient base is less than the diameter of thread bottom inner chamber in the pipe joint, and the rear end diameter of trapezoidal salient base equals or be greater than the diameter of thread bottom inner chamber in the pipe joint, and trapezoidal salient base can be filled in in pipe joint in the thread bottom inner chamber, it has the recess that can overlap ring type seal to open on the step that the rear end and the end cap body handing -over place of trapezoidal salient base formed. When trapezoidal salient base stopper in pipe joint in the thread bottom inner chamber time, ring type seal can seal the opening step department of screwed joint bottom inner chamber in the pipeline, and can play the effect of sealed leak -stopping.
Description
Technical field
This utility model relates to pipe joint plug, particularly for the external screw thread plug of the direct water blockoff of pipeline female adapter.
Background technology
External screw thread plug is pipe fitting conventional during water-heating system is installed, and it is mainly used in blocking the female thread of pipe end, and plays the effect of sealing, to prevent the leakage of pipe end female thread.At present when using external screw thread plug, it is the most all to be wound around raw material band in the above or on band ear plug, overlap O RunddichtringO, reaches the effect of sealing with this.But using to be wound around when raw material band has following defects that use wastes time and energy, and sealing effectiveness is the best, once suppresses examination, weeping often occurs；Use O RunddichtringO when having following defects that use, usually can cause the displacement deformation of O RunddichtringO because overexerting; thus do not reach the effect sealing leak-stopping; and when suppressing examination; because hydraulic pressure is bigger; usually O RunddichtringO can be ejected original position; make the sealing ring cannot be spacing, and then cause pipeline to leak air, leak.
Summary of the invention
The purpose of this utility model is to provide a kind of external screw thread plug for the direct water blockoff of pipeline female adapter, and sealing ring thereon will not shift and can preferably block pipeline, without leaking air, leaking.
The purpose of this utility model is realized in, the described external screw thread plug for the direct water blockoff of pipeline female adapter, including internal-external hexagon plug and plug body, described internal-external hexagon plug is connected with plug body, it is characterized in that: at plug, this most external is shaped with external screw thread, the trapezoidal protrusion base extended forward it is provided with in the front end of plug body, the diameter of described trapezoidal protrusion base is less than the diameter of plug body, the point diameter of trapezoidal protrusion base is less than the diameter of inner chamber bottom pipe joint female thread, the rear end diameter of trapezoidal protrusion base is equal to or more than the diameter of inner chamber bottom pipe joint female thread, trapezoidal protrusion base can be filled in bottom pipe joint female thread in inner chamber；The step that the rear end of trapezoidal protrusion base and plug body handing-over place are formed has the groove of energy collar-shaped sealing ring.
Being connected between internal-external hexagon plug with plug body and have block, the turning below block and between external screw thread is provided with on O groove, O groove and is cased with sealing ring.
The beneficial effects of the utility model are: this utility model is provided with the trapezoidal protrusion base extended forward in the front end of plug body, and when pipeline female adapter is tightened by external screw thread plug, trapezoidal protrusion base is directly filled in bottom pipeline female adapter in inner chamber；The step that trapezoidal protrusion base and plug body handing-over place are formed has the groove of energy collar-shaped sealing ring, O-ring seal is difficult to from groove displacement, when trapezoidal protrusion base plug bottom pipe joint female thread in inner chamber time, O-ring seal can be sealed at the opening step of inner chamber bottom pipeline female adapter, and can play the effect sealing leak-stopping.Additionally it is connected between internal-external hexagon plug with plug body and has block, below block, the external screw thread turning with body has O groove, it is cased with sealing ring on o-ring groove, when external screw thread plug is tightened, O groove below block can cover sealing ring has suburb to prevent sealing ring displacement deformation or hydraulic pressure large sealing packing ring from ejecting, so that the opening part of block and pipeline female adapter more seals；Reach preferably to seal.This utility model has simple in construction, can reach triple seal effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 1-1 is the structural representation of trapezoidal protrusion base of the present utility model.
Fig. 2 is the structural representation that this utility model is connected with three way cock.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
See Fig. 1, Fig. 1-1 and Fig. 2, a kind of external screw thread plug for the direct water blockoff of pipeline female adapter described in the utility model, including internal-external hexagon plug 1 and plug body 8, described internal-external hexagon plug 1 is connected with plug body, its construction features is at this external external screw thread 4 that is shaped with of plug, the trapezoidal protrusion base 7 extended forward it is provided with in the front end of plug body, the diameter of described trapezoidal protrusion base 7 is less than the diameter of plug body, the front end 7-2 of trapezoidal protrusion base is less than the diameter of inner chamber 9 bottom pipe joint female thread, the rear end 7-1 of trapezoidal protrusion base is equal to or more than the diameter of inner chamber 9 bottom pipe joint female thread, trapezoidal protrusion base or anterior or middle front part can be filled in bottom pipe joint female thread in inner chamber；The step that rear end 7-1 and the plug body handing-over place of trapezoidal protrusion base are formed has the groove 10 of energy collar-shaped sealing ring 5, the preferred annular groove of described groove so that O-ring seal 5 is difficult to from groove displacement, and can play the effect of sealing leak-stopping.
In said structure, it is connected between internal-external hexagon plug 1 with plug body and has block 2, block 2 is easy to the opening outer with pipeline female adapter 10 and is sealed, O RunddichtringO 3 can be cased with, so that the opening outer of block 2 and pipeline female adapter more seals on the plug body 8 of block 2；Reach preferably to seal.
Above embodiment is only preferred embodiment to be described this utility model; not scope of the present utility model is defined; on the premise of relating to spirit without departing from this utility model; various deformation and improvement that the technical solution of the utility model is made by those of ordinary skill in the art each fall within the protection domain that claim of the present utility model determines; such as will be only used in the external thread wire of the direct water blockoff of pipeline female adapter to get lodged in and be changed in material, copper change rustless steel, cast iron or aluminium alloy into and fall into protection domain of the present utility model equally.
