Description
Technical field
This utility model relates to a kind of quick connector, is specifically related to a kind of self-closing quick connector.
Background technology
Multiple airflow pipeline can be used, in order to be coupled together by these conveyance conduits, just on mechanization automatic equipment
The joint of various variety classes and function can be used.Existing quick connector does not possess automatic closing function, after flexible pipe is extracted,
This quick connector is conducting, is easily caused gas leakage, thus brings great inconvenience, and existing fast grafting to user
Head there is also structure complexity, the defect of unstable properties.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, it is provided that a kind of simple in construction, stable and reliable for performance,
Self-closing quick connector easy to use.
For achieving the above object, this utility model uses a kind of self-closing quick connector, including valve body, air pipe sleeve, described
Valve body in be provided with valve pocket, the two ends of valve body are respectively arranged with the air inlet being connected with valve pocket and gas outlet, described
Being provided with die in gas outlet, described air pipe sleeve is installed in die, is provided with spring leaf, trachea in valve pocket at corresponding die
Conflicting on spring leaf in the lower end of set, is provided with core assembly in valve pocket, and described core assembly includes spool, spring and spool
The sealing ring matched, the both sides of sealing ring are located between corresponding spring leaf and back-up ring in being respectively arranged with a back-up ring, and valve pocket
Being provided with packing ring, conflicts on the lower end of spool in one end of described spring, the other end conflict of spring limit in air inlet
In the chuck of position.
The beneficial effects of the utility model are: this self-closing quick connector has simple in construction, stable and reliable for performance, use
Advantage easily, this quick connector possesses automatic closing function, is inserted in valve pocket from air pipe sleeve by flexible pipe, and flexible pipe promotes valve
Core, spool compression spring, spool moves past sealing ring, now, and spring leaf locking flexible pipe, i.e. this quick connector conducting；Work as operator
Member's pressing air pipe sleeve, air pipe sleeve promotes spring leaf, and flexible pipe loses the restriction of spring leaf, after flexible pipe is extracted by operator, spool
Losing the restriction of flexible pipe, spool returns in situ, and now, sealing ring coordinates with seal spool, i.e. this quick connector is closed.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram.
Detailed description of the invention
As it is shown in figure 1, this utility model embodiment is a kind of self-closing quick connector, including valve body 10, air pipe sleeve 12, institute
It is provided with valve pocket 101 in the valve body 10 stated, the two ends of valve body 10 are respectively arranged with the air inlet 102 being connected with valve pocket 101
With gas outlet 103, being provided with die 11 in described gas outlet 103, described air pipe sleeve 12 is installed in die 11, valve pocket
Being provided with spring leaf 13 at corresponding die 11 in 101, conflicts on spring leaf 13 in the lower end of air pipe sleeve 12, arranges in valve pocket 101
Core assembly 20, described core assembly 20 is had to include the sealing ring 23 that spool 21, spring 22 match, sealing ring with spool 21
The both sides of 23 are respectively arranged with a back-up ring 24, and in valve pocket 101, between corresponding spring leaf 13 and back-up ring 24, place is provided with packing ring
14, conflict on the lower end of spool 21 in one end of described spring 22, the other end conflict of spring 22 limit in air inlet 102
In the chuck 104 of position.This self-closing quick connector has simple in construction, advantage stable and reliable for performance, easy to use, this fast grafting
Head possesses automatic closing function, is inserted in valve pocket from air pipe sleeve by flexible pipe, and flexible pipe promotes spool, spool compression spring, spool
Move past sealing ring, now, spring leaf locking flexible pipe, i.e. this quick connector conducting；When operator press air pipe sleeve, and air pipe sleeve pushes away
Moving reed, flexible pipe loses the restriction of spring leaf, and after flexible pipe is extracted by operator, spool loses the restriction of flexible pipe, and spool is extensive
Multiple in situ, now, sealing ring coordinates with seal spool, i.e. this quick connector is closed.
