Abstract
The utility model discloses a kind of equal coupling, comprise metal tube, described metal tube two ends are separately installed with a straight cutting loose joint, and described straight cutting loose joint comprises valve body, is arranged with core retainer plate in described valve body, in described core retainer plate, spool is installed, be separately installed with Returnning spring and seal ring between described spool and core retainer plate, described spool be provided with plug and outlet pipe, in described outlet pipe, offer exhalant canal, described spool offers side through hole, and described side through hole is connected with exhalant canal.Thus reach and directly can plug externally connected pipe, externally connected pipe is extracted rear water-tight and can connect the effect of two externally connected pipe.
Description
Technical field
The utility model relates to joint, particularly relates to a kind of equal coupling.
Background technique
Plastic pipe union in the market, mainly contain binodal, elbow, threeway etc., generally comprise joint body, one end of joint body is provided with and the connecting head moulded pipe and coordinate, the other end of joint body is provided with fixed interior tooth joint, and the plastic pipe union of this structure cannot meet the demand that on market, complex pipeline connects.
Model utility content
The purpose of this utility model is to provide a kind of equal coupling, has and directly can plug externally connected pipe, and externally connected pipe is extracted rear water-tight and can connect the feature of two externally connected pipe.
In order to achieve the above object, the technological scheme that the utility model provides is: comprise metal tube, described metal tube two ends are separately installed with a straight cutting loose joint, described straight cutting loose joint comprises valve body, core retainer plate is arranged with in described valve body, in described core retainer plate, spool is installed, Returnning spring and seal ring is separately installed with between described spool and core retainer plate, described spool is provided with plug and outlet pipe, exhalant canal is offered in described outlet pipe, described spool offers side through hole, and described side through hole is connected with exhalant canal.
Described plug offers Returnning spring mounting groove, in described Returnning spring mounting groove, Returnning spring is installed.
Described metal tube and valve body manufacture form.
The beneficial effects of the utility model are: the utility model passes through: comprise metal tube, described metal tube two ends are separately installed with a straight cutting loose joint, described straight cutting loose joint comprises valve body, core retainer plate is arranged with in described valve body, in described core retainer plate, spool is installed, Returnning spring and seal ring is separately installed with between described spool and core retainer plate, described spool is provided with plug and outlet pipe, exhalant canal is offered in described outlet pipe, described spool offers side through hole, and described side through hole is connected with exhalant canal.Thus reach and directly can plug externally connected pipe, externally connected pipe is extracted rear water-tight and can connect the effect of two externally connected pipe.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;

Embodiment
Embodiment 1
A kind of equal coupling as Figure 1-3, comprise metal tube 1, described metal tube 1 two ends are separately installed with a straight cutting loose joint 3, described straight cutting loose joint 3 comprises valve body 5, core retainer plate 6 is arranged with in described valve body 5, in described core retainer plate 6, spool 7 is installed, Returnning spring 8 and seal ring 9 is separately installed with between described spool 7 and core retainer plate 6, described spool 7 is provided with plug 10 and outlet pipe 11, exhalant canal is offered in described outlet pipe 11, described spool 7 offers side through hole 12, and described side through hole 12 is connected with exhalant canal.When externally connected pipe inserts straight cutting loose joint 3, spool promotes by externally connected pipe in joint, thus makes side through hole 12, is connected with core retainer plate internal channel, and metal tube 1 is connected with externally connected pipe.When extracting externally connected pipe, spool 7 promotes by Returnning spring in core retainer plate, thus makes plug and core retainer plate close contact, and seal ring reaches sealing effect simultaneously, thus makes straight cutting loose joint 3 automatic shutoff.
Described plug 10 offers Returnning spring mounting groove 13, in described Returnning spring mounting groove 13, Returnning spring 8 is installed.Returnning spring is installed more stable.
Described metal tube 1 and valve body 5 is integrally manufactured forms.Make straight-through female adapter sealability better.
