It specifically, further include two ring flat-plates, two clamping pieces pass through flexible blockage plate described in the two ring flat-plate biass respectively.
Preferably, further including a pipe sleeve being placed on the pipeline, the pipe clamp and the flexible blockage plate are placed on institute
It states on pipe sleeve.
Detailed description of the invention
Fig. 1 is cross-sectional view when this flexible blockage device is set between equipment and pipeline.
Fig. 2 is the perspective view of this device for flexible encapsulation.
Fig. 3 is the structural schematic diagram of flexible blockage plate in this flexible blockage device.
Specific embodiment
Description is made to the preferred embodiment of the utility model below with reference to the Figure of description provided.
In conjunction with shown in Fig. 1 to Fig. 3, the utility model provides a kind of flexible blockage device, for blocking in equipment 2 and pipeline
Between 3, to prevent foreign matter from entering pipeline 3, equipment 2 in the construction process.In the interface 21 that pipeline 3 is inserted into equipment 2 and manage
Road 3 and equipment 2 are clearance fit, have gap between the inner wall of interface 21 and the outer peripheral surface of pipeline 3.
Flexible blockage device includes pipe sleeve 11, pipe clamp, ring flat-plate 13 and flexible blockage plate 14, and wherein the length of pipe sleeve 11 is big
In the length of pipe clamp, ring flat-plate 13 and flexible blockage plate 14.11 sets of the pipe sleeve positions being located at interface 21 on pipeline 3, and have portion
It point extend into interface 21, the pipe sleeve 11 in the present embodiment is the big arc close to full circle, thinner thickness, therefore has certain become
Shape ability, is suitable for 3 size of pipeline, and pipe sleeve 11 is also possible to complete circle.Flexible blockage plate 14 in a ring and is covered in pipe sleeve
On 11, and flexible blockage plate 14 is posted by equipment 2 around 21 ground of interface, and the specific structure of flexible blockage plate 14 will be in following theory
It is bright.
Pipe clamp includes the clamping piece 121 of two arcs, and two 121 sets of clamping pieces are on pipe sleeve 11 and the end of two clamping pieces 121
Fixation is separably docked in portion, so that two clamping pieces 121 can be positioned with respect to pipe sleeve 11, pipeline 3.Specifically, clamping piece 121
End is threadedly coupled after there is the docking section 122 being parallel to each other, a bolt 124 to pass through two docking sections 122 with a nut 125.When
Nut 125 can be realized the docking of two clamping pieces 121 and fix when tightening.
Ring flat-plate 13 is also there are two arc and quantity, not have ring flat-plate 13 corresponding with two clamping pieces 121 respectively.Ring flat-plate 13 is located at folder
Between gripping member 121 and flexible blockage plate 14.Clamping piece 121 applies flexible blockage plate 14 by ring flat-plate 13 after positioning on pipe sleeve 11
Pressure, is biased towards equipment 2 for flexible blockage plate 14 and is adjacent to equipment 2.Adjustable angle between clamping piece 121 and ring flat-plate 13 leads to
It crosses and the front and rear sides face of clamping piece 121 is made into not parallel and is realized with certain inclination angle, then ring flat-plate 13 can be biased flexibility
Plugging plate 14 adapts to 2 metope of equipment with inclination angle.Each ring flat-plate 13 can also be first fixed with corresponding clamping piece 121.
When installation, flexible blockage plate 14 is first placed on pipeline 3 to and is adjacent to 21 position of interface, is then inserted in ring flat-plate 13 and pipe
Pipe sleeve 11, is finally inserted in, with 124 nut of bolt, 125 Duct fixing clamp by folder.The flexible blockage apparatus structure of this structure is simple,
It is convenient for disassembly and assembly, it is conveniently replaceable and safeguards.
Since pipe sleeve 11 and the contact area of pipeline 3 are larger, can be avoided when clamping piece 121 directly clamps pipeline 3 to pipe
Road 3 causes to damage, if but do not consider this factor, pipe clamp can also be clamped directly on pipeline 3.Due to clamping piece 121
Rear end area is smaller, therefore works as clamping piece by the bigger ring flat-plate 13 of contact area come 14 better effect of bias flexible blockage plate
121 are then not provided with ring flat-plate 13 when sufficiently thick can also be with.
The specific structure is shown in FIG. 3 for flexible blockage plate 14 comprising the first plugging plate 141 of arc and the second plugging plate
142, the both ends of the first plugging plate 141 are separably docked with the both ends of the second plugging plate 142 respectively.Specifically, first blocks
Two ends of plate 141 are respectively equipped with groove 146 and holding section 147, and two ends of the second plugging plate 142 are also respectively equipped with holding section
147 with groove 146, the first plugging plate 141 and the second plugging plate 142 can be achieved by the way that holding section 147 to be caught in groove 146
Docking.First plugging plate 141 is equipped with multiple gaps, these gaps radially extend and include extending to the first plugging plate
First gap 143 of 141 inward flanges and outer peripheral second gap 144 for extending to flexible blockage plate 14, the first gap 143
It is arranged alternately on the first plugging plate 141 setting with the second gap 144.Likewise, also being provided with first on the second plugging plate 142
Gap 143 and the second gap 144.By the way that the first gap 143, the second gap 144 are arranged on flexible blockage plate 14, can make soft
Property plugging plate 14 shows deformable flexible in structure.
The quantity of flexible blockage plate 14 can be for one or multiple in flexible blockage device, in the present embodiment diagram
Specially three.
Compared with prior art, since the flexible blockage plate 14 in the utility model flexible blockage device is posted by equipment 2
Interface 21 at and equipment 2 is biased towards by pipe clamp, therefore can keep in the construction process to equipment 2 interface 21 and pipeline 3 it
Between closure, effectively prevent foreign matter by being entered in equipment 2 or pipeline 3 at interface 21.Again due to pipe clamp be placed on pipeline 3 it
On without being put into inside pipeline 3, therefore can't be limited in pipeline 3 end nearby and can be set on pipeline 3
Any position, the flexibility, adaptability when site layout project are higher.In addition, flexible blockage plate 14 is equipped with gap therefore in structure
It is upper that there is certain flexibility, and flexible blockage plate 14 is not fixed with pipeline 3, therefore the vibration on pipeline 3 in the construction process
Dynamic loading, which can be isolated, to be conducive to keep pipeline 3 and the structure of equipment 2 in the construction process without being transmitted in equipment 2
Completely.Finally, the present apparatus is simple in construction, easy to disassemble and assemble, convenient for safeguarding and replacement.
Above disclosed is only the preferred embodiments of the utility model, and effect is to facilitate those skilled in the art
Understand and implement accordingly, the interest field of the utility model cannot be limited with this certainly, therefore special according to the present utility model application
Equivalent variations made by sharp range still falls within the range that the utility model is covered.
