Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, below in conjunction with attached drawing, to the present invention make into
One step is described in detail.
As shown in Figs. 1-2, one kind safely disconnecting valve, including left valve barrel 1, right valve barrel 2, left spool 3, right spool 4, intermediate sleeve
5 and drawstring combination 6, left valve barrel 1 is equipped with left raised 12 by the peripheral outer wall of right end, and the left side wall of the left protrusion is equipped with the
One inclined-plane 121, right valve barrel 2 are equipped with right raised 22 symmetrical with left protrusion, the right side wall of right protrusion by left end peripheral outer wall
It is equipped with the second inclined-plane 221, is set on the second inclined-plane there are two through-hole 222, the first inclined-plane is set and during the second inclined-plane can be conducive to
Between the disengagement that covers;Intermediate sleeve 5 includes two bodies 51 and is installed in two guide bodies 52 of two body sides respectively, body and
First inclined-plane and the second inclined-plane are adapted, and body can be fastened in the left protrusion and right protrusion of through hole, and guide body is used for
Body is set to carry out effectively fixed clamping to left protrusion and right protrusion;;Guide body includes the sleeve 521 being installed on body, inner sleeve
In sleeve and the lock pillar 522 to match with through-hole, the elastic component for being connected in the connecting rod 523 of lock pillar rear end and being socketed on connecting rod
524, the tail end of connecting rod extends to outside sleeve and combines with drawstring connection, and lock pillar, which is inserted into through-hole, can be conducive to keep body convex with the right side
Play fastening;It is equipped with the left supported plate 11 for installing left spool in left valve barrel, precompressed elastic is equipped between left spool and left supported plate
Part 7, is equipped with the right supported plate 21 for installing right spool in right valve barrel, and left supported plate is equipped with multiple first perforation 111, on right supported plate
Equipped with multiple second perforation 211, the first perforation of setting is perforated with second can guarantee that the connection of left valve barrel and right valve barrel needs;Right valve
Precompressed elastic part 7, left valve barrel and right valve barrel is equipped between core and right supported plate to be clamped by intermediate sleeve;Drawstring combination 6 includes drawing
Rope 61 and two fasteners 62 that drawstring both ends are arranged in, fastener one end detachably connects with 523 part of connecting rod outside sleeve 521
It connects, is equipped in the rear side of two fasteners for adjusting two elastic guide members 63 of drawstring, guide member includes being installed in
The adjusting bolt 632 of the ontology 631 and setting passed through in right valve barrel peripheral outer wall for drawstring on the body.
A kind of working principle for safely disconnecting valve of the present invention is:
When left valve barrel connect closure with right valve barrel, two intermediate sleeves are respectively symmetrically connected to left valve barrel and set with right valve barrel end
For the left protrusion set in right protrusion, lock pillar in guide body can carry out effective clamping to body, and the elastic component by being equipped with
Being closed left valve barrel and right valve barrel, fastening is reliable, and left spool mutually presses under the effect of precompressed elastic part elastic force with right spool,
Drawstring combination fastening member be connected with the connecting rod of lock pillar rear end, when pulling drawstring, lock pillar compression elastic piece to be detached from through-hole,
Left protrusion disengages together with the first inclined-plane in right protrusion with the second inclined-plane smoothly making the related body of guide body, what intermediate sleeve disengaged
Moment separates left valve barrel at once with right valve barrel under the effect of precompressed elastic part elastic force, while precompressed elastic part elastic force makes a left side
Sealing is truncated in spool and right spool difference pressure on opposite left valve barrel and right valve barrel end wall, to effectively realize peace
Sealing and defencive function when full kick-off valve disconnects need, while fixed, and structure is simple, can again be clamped intermediate sleeve
Protection is broken in implementation, has Reusability, practical feature.
Of the invention safely disconnects valve in the specific implementation, safely disconnects the drawstring of valve by dropping and breaks guarantor to trigger
Shield, to avoid hose or Flanged Connection System by excess load tension or non axial tension;It need to guarantee to connect when installation
It connects and safely disconnects the pulling rope length of valve and live fixing end and must be smaller than the limiting length of the pipeline that it is protected;In addition it predicts
The motion direction of mobile vehicle, it is ensured that in the case where disagreeing outer situation, drawstring tightens in advance always, the stress before pipeline always;
The elastic component elastic force of adjustable guide body or the adjusting bolt precompression on adjustable guide component are simultaneously to adjust change drawstring
Pulling-out force, the different application needs of complex environment can be met;After safety kick-off valve, which triggers, to be separated, a left side for parting surface two sides
Spool and right spool can close rapidly sealing, avoid the fluid leakage of cleaved facet, effective protection operator and peripheral ring
The safety in border.
As further improvement to above-mentioned technical proposal, for the location and installation convenient for left valve barrel, left valve barrel 1 is in cylinder
Shape is equipped with positioning convex platform 13 on the right side of left valve barrel.
As further improvement to above-mentioned technical proposal, for the cooperation and location and installation convenient for right valve barrel and left valve barrel,
Right valve barrel 2 is cylindrical, the positioning groove 23 being adapted with positioning convex platform is equipped on the left side of right valve barrel, on positioning groove
Equipped with the first sealing ring 24, the leakproofness that the first sealing ring is set when can guarantee left valve barrel and right valve barrel closure.
Further, drawstring 61 is made of Steel material, and the tensile mechanical properties of Steel material are good, using reliable, can meet
Pull-off force application needs.
Further, the right side of left spool 3 is equipped with the second sealing ring 31, and the left side of right spool 4 is equipped with third
Sealing ring 41, be arranged the second sealing ring and third sealing ring can guarantee break rear left valve barrel and right valve barrel it is respective instantaneously close it is close
Feng Xing is not easy to leak, good airproof performance, can meet the use needs of different discharge pressure fluids.
Above explanation and examples are merely exemplary, it is not intended to limit the scope of the present invention in any way.This field
Technical staff should be understood that without departing from the spirit and scope of the invention can details and shape to inventive technique scheme
Formula is modified or is replaced, but these modifications and replacement are fallen within the protection scope of the present invention.
