Description
Technical field
The present invention relates to assemble manufacture field, be specifically related to the airtight blocking device of a kind of technique.
Background technology
In assembling manufacturing fields such as Aeronautics and Astronautics, automobile, boats and ships, need to use in a large number various seal cases (tank body), except fuel tank, also have many cavity, casing and tank bodies that provide pressurized air, hydraulic pressure wet goods to seal.These casings (or tank body), in the links of manufacture, assembling, use and maintenance and repair, all need to carry out a large amount of leakage tests or detection, to verify its compressive sealed performance.And the sealing property of these casings or tank body is as critical index, whole system is had very important significance, sometimes even can affect the safety of assembling finished product.
In the time carrying out tightness test, first must, by all lids and interface channel sealing or shutoff, guarantee the complete sealing without leakage of these passage lids in process of the test, and can be at certain hour condition Resistance Test medium and pressure.Conventionally, similar test is all to adopt finished product cap, lid to carry out shutoff, or adopt special obstruction to carry out shutoff.
For screw thread or quick-release lid, adopt finished product cap, lid to carry out the method for shutoff, this not only needs to expend a large amount of finished products, uncertainly can guarantee sealing effectiveness.Conventionally finished product cap, lid are very short serviceable life, and learies is large, and result of use is undesirable.For the connection tubing passway without screw thread or other quick-release connected modes, conventionally adopt the special obstruction with O-ring seal to carry out shutoff.In actual use, often occur that sealing effectiveness is poor, O-ring seal destroys, O-ring seal cannot use etc. problem after expanding, and, need to customize the obstruction of dimension for different bores, the obstruction of using a large amount of all sizes due to on-the-spot meeting, cannot exchange again, use very inconvenient.
Utility model content
For the method for the employing finished product existing in prior art or O-ring seal carry out airtight obstruction and the finished product learies that forms large, use inconvenient technical matters; The utility model provides a kind of highly versatile, airtight blocking device that sealing effectiveness is good.
A kind of airtight blocking device, is characterized in that: comprise bolt of long stem, nut, soft material, bottom surface backing plate, positioning backing plate; Described soft material is with round center hole, and positioning backing plate also has round center hole; Bolt of long stem is fixed on the backing plate of bottom surface, and the screw rod of bolt of long stem passes after the center pit of the center pit of soft material, the backing plate of transposing successively, and nut is screwed in to screw rod.
Airtight blocking device in the utility model, has taked the soft material of compressible distortion, by the positioning backing plate application of force, makes same obstruction can adapt to the mouth of pipe of multiple close specifications, has saved a large amount of special obstruction or finished product.The present invention can also improve tightness test, testing efficiency and reliability greatly, greatly reduces specially/common processes and stops up input, has application value very widely in fields such as Aeronautics and Astronautics, automobile, boats and ships.
Accompanying drawing explanation:
The bright drawing of the utility model is described as follows:
Fig. 1 is process principle figure of the present invention;
In figure: 1. the screw rod 2. nuts 3. backing plate 4. rubber bar 5. bottom surface backing plates of transposing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described as follows:
A kind of airtight blocking device, is characterized in that: comprise bolt of long stem, nut 2, soft material, bottom surface backing plate 5, positioning backing plate 3; Described soft material is with round center hole, and positioning backing plate 3 also has round center hole; Bolt of long stem is fixed on bottom surface backing plate 5, and the screw rod 1 of bolt of long stem passes after the center pit of the center pit of soft material, the backing plate of transposing successively, and nut 2 is screwed in to screw rod.
When use, only the airtight blocking device assembling need to be put into the hole or the lid that need obstruction, then screw nut 2, nut 2 is to positioning backing plate 3 application of forces, positioning backing plate 3 extrusion soft materials, then soft material distortion, is formed on the airtight obstruction at hole or lid place.
Because of rubber bar 4 good springiness, wear-resistant, so described soft material is selected rubber bar 4.
Because vulcanized rubber has low-density, soft, good, the corrosion resistant feature of impermeability, so described rubber bar 4 is produced through vulcanizing.
When the described not squeezed state as glue rod, be Rotary-table, the end of small end contacts with bottom surface backing plate 5, and diameter is than the approximately little 1～5mm of nozzle diameter that needs sealing.
When the described not squeezed state as glue rod, be circle drum shape, maximum gauge, than the approximately little 1～5mm of nozzle diameter that needs sealing, can improve sealing result of use.
For improving compression-expansion efficiency, described rubber bar 4 surfaces are complete, and barred body inside has hole.
Described rubber bar 4 make foamed core body.
For improving the work efficiency in airtight obstruction process, described nut 2 is selected fast locknut 2.
Bottom surface backing plate 5 is compared with the little 3～5mm of rubber bar 4 end diameter, and positioning backing plate 3 is compared with the little 3～5mm of rubber bar 4 outside diameter.
Steel plate thickness, according to working strength requirement, generally adopts the stainless steel of 3～10mm thickness or No. 45 steel plates to make.
Protection scope of the present invention is not limited only to the disclosed technical scheme of embodiment part, and all methods of utilizing bolt and two blocks of backing plate extrusion soft materials to carry out airtight obstruction all fall into protection scope of the present invention.
