Specific embodiment
To make the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with accompanying drawing, the present invention is made into
One step is described in detail.
As shown in Figure 1-2, a kind of Pull breaking ualve, including left valve barrel 1, right valve barrel 2, left valve element 3, right valve element 4, the and of intermediate sleeve 5
Drawstring combination 6, is provided with the left supported plate 11 for installing left valve element in left valve barrel, left valve barrel 1 is cylindrical, is kept right end in left valve barrel
Peripheral outer wall be provided with left raised 12, raised left side wall is provided with the first inclined-plane 121, is provided with the right side of left valve barrel
Positioning boss 13；Right valve barrel 2 is cylindrical, and the right projection symmetrical with left projection is provided with right valve barrel keeps left end peripheral outer wall
22, right raised right side wall is provided with the second inclined-plane 221, and the second inclined-plane is provided with two through holes 222, sets the first inclined-plane and the
Two inclined-planes can be beneficial to the disengagement of intermediate sleeve；Precompressed elastic part 7 is provided between left valve element and left supported plate, be provided with right valve barrel for
The right supported plate 21 of right valve element is installed, precompressed elastic part 7 is provided between right valve element and right supported plate, during left valve barrel passes through with right valve barrel
Between cover clamping, drawstring combination is connected between putting；The positioning being adapted with positioning boss is provided with the left side of right valve barrel
Groove 23, detent is provided with the first sealing ring 24, sets when the first sealing ring can ensure that left valve barrel is closed with right valve barrel
Sealing, setting positioning boss can be beneficial to location and installation with detent cooperation；Intermediate sleeve 5 is solid including two bodies 51 and respectively
Two the two of body side guide bodies 52 are located at, body and the first inclined-plane and the second inclined-plane are adapted, and body can be fastened in position
In in the left raised and right projection of through hole, guide body is used to make body effectively be fixed clamping to left raised and right projection；
Guide body include be installed on body sleeve 521, it is interior be placed on sleeve and match with through hole lock 522, be connected in lock
The connecting rod 523 of rear end and the elastic component 524 being socketed on connecting rod, the tail end of connecting rod are extended to outside sleeve, and lock is inserted into through hole
Inside make body with right raised fastening；Drawstring combination 6 includes drawstring 61 and is arranged on two fasteners 62 at drawstring two ends, fastener
One end is detachably connected with the shaft portion outside sleeve, and two elastic for adjusting drawstring are provided with rear side of two fasteners
Guide member 63, guide member is including being installed in right valve barrel peripheral outer wall the body 631 passed through for drawstring and being arranged on this
Regulating bolt 632 on body.
A kind of operation principle of Pull breaking ualve of the present invention is：
When left valve barrel is connected closure with right valve barrel, two intermediate sleeves are respectively symmetrically and are connected to left valve barrel and are set with right valve barrel end
In the left raised and right projection put, the lock in guide body can carry out effective clamping to body, and by the elastic component that is provided with
Make left valve barrel and right valve barrel closure fastening reliable, left valve element mutual top pressure under the effect of precompressed elastic part elastic force with right valve element,
