It states the insertion of the first sealing ring bottom to be arranged in the first ring groove, top extends the upper table for protruding from the second shell
Face, the insertion of second sealing ring bottom are arranged in the second ring groove, and top, which extends, protrudes from the second shell
Upper surface and the outside for being located at first sealing ring, form a ring-type between first sealing ring and the second sealing ring and are used for
The collecting tank of leaking medium is collected, offers deflector hole in the collecting tank, the end of the deflector hole extends to described second
The outside of shell, the exit of the deflector hole are connected with unidirectionally stifled valve.
In one preferred embodiment of the utility model, first sealing ring and the second sealing ring be distributed in concentric circles and
For close ring.
In one preferred embodiment of the utility model, the twice ring groove is taken shape in second shell.
In one preferred embodiment of the utility model, the deflector hole is vertical deflector hole, and end extends through
The lower surface of the second shell.
In one preferred embodiment of the utility model, the deflector hole is L-shaped structure, and end is prolonged in the horizontal direction
Stretch and run through the lateral surface of the second shell.
In one preferred embodiment of the utility model, the exit of the unidirectional stifled valve is provided with detection warning device.
The beneficial effects of the utility model are: a kind of novel double-layer sealing early warning structure is provided, the structure of double-layer seal rings,
There is a cricoid leakage collecting tank between two sealing rings, once there is medium to leak out through deflector hole from the outlet of unidirectional stifled valve
Come, detection warning device can receive the information that a certain region of the first sealing ring starts leakage at the first time, at this time the second sealing
Circle does not occur the scar of penetrability, and good seal performance is convenient timely to repair, can relatively quick processing leakage problem, peace
Full performance is high, maintenance cost is low.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is that figure is cutd open in one preferred embodiment of novel double-layer sealing early warning structure of the utility model；
Fig. 2 is that the novel double-layer sealing early warning structure another preferred embodiment of the utility model cuts open figure；
Fig. 3 is the distribution schematic diagram of two sealing rings in the novel double-layer sealing early warning structure of the utility model；
Fig. 4 is the structural schematic diagram that valve is unidirectionally blocked up in the novel double-layer sealing early warning structure of the utility model.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Fig. 1-4 is please referred to, the utility model embodiment includes: a kind of novel double-layer sealing early warning structure, comprising: first shell
Body 1, second shell 2, the first sealing ring 3 and the second sealing ring 4, the first shell 1 is detachable to be fixed on second shell 2
Top, the two generally use bolt and nut 11 to tighten fixation, and the outside usually in second shell 2 positioned at the second sealing ring 4 is set
It is equipped with the bolt hole 12 being used cooperatively with bolt and nut 11, the bolt hole 12 equidistantly divides around 2 center of circle direction of second shell
Cloth setting is equipped with twice ring groove in the contact surface of second shell 2 and first shell 1, and twice ring groove takes shape in the
On two shells 2,3 bottom of the first sealing ring insertion is arranged in the first ring groove 5, and top, which extends, protrudes from second shell
The upper surface of body 2,4 bottom of the second sealing ring insertion are arranged in the second ring groove 6, and top, which extends, protrudes from second
The upper surface of shell 2 and the outside for being located at first sealing ring 3, form between first sealing ring 3 and the second sealing ring 4
One is cyclic annular for collecting the collecting tank 7 of leaking medium, offers deflector hole 8, the entrance of the deflector hole 8 in the collecting tank 7
It is provided between two adjacent bolts hole 12, the outlet of 8 end of deflector hole extends to the outside of second shell 2, the water conservancy diversion
The exit in hole 8 is connected with unidirectionally stifled valve 9.
In specific embodiment, first shell 1 and second shell 2 can be the shell of plurality of devices, such as pipe flange,
Pressure vessel enclosure, pressure vessel cover board, inspection manhole door, valve body, valve deck, heat exchanger shell, ball seat etc., can basis
It needs, as shown in Figure 1, setting L-shaped structure for deflector hole 8, end is horizontally extending and is through to second shell 2
Lateral surface.
In another specific embodiment, as shown in Fig. 2, setting deflector hole 8 to the deflector hole of vertical direction, end is direct
Extend through the lower surface of the second shell 2.
First sealing ring 3 and the second sealing ring 4 is in concentric circles distribution setting, the exit of the unidirectional stifled valve 9
The a certain region of sealing ring can be received at the first time and start to let out once there is dielectric leakage to come out by being provided with detection warning device 10
The information of leakage after generally receiving leakage information, takes the mode of fastening nut to handle at the first time, if by fastening nut
It can not solve to leak, the plug 91 of unidirectional stifled valve can be tightened inward, further medium be prevented to leak out, even if unidirectional stifled
Continue to leak at valve outlet, pressure sealing gum-injecting port can be screwed in this exit, first the plug of unidirectional stifled valve is carried out, is reserved
The space that certain channel gives stifled jelly to flow into deflector hole and leakage collecting tank, directly suppresses injecting glue, to injecting glue after,
Plug is again switched off, can be stopped a leak substantially, this scheme can remove the dangerous behaviour of live aperture or production, mounting tool from
Make, at the same can relatively rapid processing leakage problem, artificial and time cost is low, and effect is good.
The beneficial effect of the utility model novel double-layer sealing early warning structure is: using the structure of double-layer seal rings, two
There is a cricoid leakage collecting tank between sealing ring, once there is medium to leak out through deflector hole from the outlet of unidirectional stifled valve,
Detection warning device can receive the information that a certain region of the first sealing ring starts leakage at the first time, and the second sealing ring is not at this time
There is the scar of penetrability, the contact surface for avoiding first shell and second shell to a certain extent generates penetrability because of leakage
Damage, as long as while the unidirectional stifled valve and removal sealing agent that more renew in overhaul of the equipments, good seal performance, safety
Energy is high, maintenance cost is low.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
