Brief description
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing of required use is briefly described in description of the prior art.It should be evident that drawings in the following description are only
It is a kind of embodiment of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, can also be extended according to the accompanying drawing providing and obtain other enforcement accompanying drawings.
Fig. 1: cross-sectional view of the present utility model；
Specific embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings:
Embodiment of the present utility model is described below in detail, the example of described embodiment is shown in the drawings, wherein ad initio
To the element that same or similar label represents same or similar element or has same or like function eventually.Below by ginseng
The embodiment examining Description of Drawings is exemplary, is only used for explaining this utility model, and it is not intended that to of the present utility model
Limit.
In description of the present utility model, it should be noted that term " on ", D score, the orientation of the instruction such as "left", "right"
Or position relationship is based on position relationship shown in the drawings, it is for only for ease of description this utility model and simplifies description, and not
It is instruction or the hint device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore not
It is understood that to be to restriction of the present utility model.
As shown in figure 1, a kind of emergent sealer is it is characterised in that include: housing 1, side door 4, flashboard axis 6, spring 10 and
Sealing valve ball 11, described housing 1 has the center-aisle 1a of the up/down perforation passing through for current supply cable 12, described housing 1 sidepiece
There is an interconnection 1b being connected with center-aisle 1a, described side door 4 is fixed in the right-hand member of interconnection 1b by screw 5
At opening, described flashboard axis 6 are threadedly connected in side door 4, and described spring 10 right-hand member pushes against on flashboard axis 6, described under normality
Sealing valve ball 11 is located in interconnection 1b and is located between left end and the cable 12 of spring 10, the diameter of described sealing valve ball 11
More than the diameter at the minimum of center-aisle 1a；Under cable 12 breaking state, the centre that described sealing valve ball 11 enters housing 1 leads to
In road 1a and block center-aisle 1a.Preferably, the left end of described flashboard axis 6 is connected with slide block 9.
When cable ruptures suddenly, cable is deviate from from center-aisle 1a, and now, sealing valve ball loses cable support,
In the presence of spring, sealing valve ball departs from interconnection 1b and enters intermediate cavity, in the presence of well inner high voltage air-flow, in closure
Between passage 1a, be effectively realized closure well inner high voltage air-flow.
Before entering cable under into well, flashboard axis special spanner can be screwed out, make sealing valve ball be in interconnection
Interior, now, spring no compresses, and is in free state, and such center-aisle 1a is unimpeded up and down, and cable can pass through, cable
Under enter construction after the completion of, flashboard axis precession 25-30mm, make spring withstand sealing valve ball, spring is in compressive state.
Further, in order that sealing valve ball preferably blocks center-aisle 1a, this emergent sealer also includes back of the body cap 2 and uses
In the seal valve seat 3 with sealing valve ball 11 cooperation closing center-aisle 1a, described back of the body cap 2 and seal valve seat 3 are fixedly installed on shell
In the center-aisle of body 1, described seal valve seat 3 is pushed against by the bottom surface of back of the body cap 2.
In order to prevent debris from entering in interconnection 1b, and particularly prevent well mesohigh air-flow by interconnection 1b
Spill, described side door 4 penetrate interconnection 1b partly on be set with sealing ring 7 and by sealing ring 7 and interconnection 1b mistake
It is full of cooperation, described sealing ring 7 is two.Certainly it is easily understood that this technical characteristic can be applicable to the various of this emergent sealer
In the technical scheme optimizing.
During use: before (1) installs, first open side door 4, extract flashboard axis 6, slide block 9, spring 10, valve ball 11 out；
(2), after first penetrating cable 12, it is sequentially loaded into valve ball, spring, slide block, flashboard axis, side door from interconnection, uses screw
Fix side door；
(3) use flashboard axis special spanner rotate counterclockwise flashboard axis, flashboard axis are rotated to side door outermost end, now, close
Pretightning force is not added between envelope valve ball and cable；
(4) it is starting point according to this, then the flashboard axis that turn clockwise, now, between sealing valve ball and cable, there is pretightning force；
(5) when cable ruptures suddenly, sealing valve ball loses the support of cable, under the pretightning force of spring acts on, sealing valve
Ball enters in housing center-aisle, if top seal component failure, the high pressure draught of sealing valve ball bottom can make valve ball upwards
Motion, with seal valve seat cooperation, seals up leakage path, preventing and treating causes bigger accident.
By way of example this utility model is illustrated above, but this utility model is not limited to above-mentioned being embodied as
Example, all any changes done based on this utility model or modification belong to the scope that this utility model claims.
