Abstract
The utility model relates to an internal-pressure automatically regulating device for a sealed container, belonging to pressure regulating equipment. The utility model which is composed of a protective cover, an expansion device, a hollow screw bolt, a plain cushion, and a screw nut is characterized in that the expansion device can automatically regulate the internal and external pressure of the sealed container.
Description
The sealed container interior pressure automatic adjusting device is the too high or too low device of a kind of internal pressure of avoiding airtight container to cause because of expanding with heat and contract with cold.
Utilize at present and the container of the equipment of carrying liquid for some.Expanding with heat and contract with cold of liquid all produces destruction to they and they seal member.With regard to the diving sealed electric-motor.The insulating oil of motor body inside.When machine operation heating is expanded, be easy to destroy its seal member and leakage of oil and reduces and just is easy to into when the built-in electrical insulation oil cooling contracts in the motor temperature that quits work, influence the work of motor.In addition, transport liquid is the container of fuel oil particularly, in order to reduce the acting force that phenomenon took place that expands with heat and contract with cold, does not allow often to fill.Produced the bump of liquid so again to chamber wall.Be commonly called as " water hammer "; To the broken effect of the same generation of container.By retrieval " the pressure regulation capsule " in utility application number 90213448.5 " submersible motors " though in certain program adjusted the internal pressure of motor.But it is confined to " submersible motor that radial dimension is less " for the inlet type submersible motor is just impracticable down.
It is wide that the purpose of this utility model provides a kind of usable range, and reliable sealed container interior pressure automatic adjusting device.
The utility model is realized with following technical scheme: accompanying drawing is that the master of this device looks cut-open view.With reference to accompanying drawing: utilizing or the top of the container of carrying liquid, making a bottom that communicates with internal tank has nut 3, the I of platform with having its opening part of making than the material (as rubber, latex) of telescopicing performance greatly the hollow breathing device of eaves to be arranged.Be fastened in the nut 3 by hollow bolt 2 and plain cushion 4 eaves, protective cover 5 usefulness spiral shells left alone without help 6 are fixed on the chamber wall the opening part of breathing device 1.Can add one on motor top for last inlet type submersible motor and prolong pipe, this device is installed in the upper end of prolongation pipe to avoid into water position.
Action principle of the present utility model is: when airtight container heating internal liquid expands, the partially liq that is expanded just is excreted in the breathing device 1, and when container cooled interior liquid contraction, liquid in the breathing device is got back to internal tank again, because the breathing device can absorb the liquid with compensation tank inside automatically, balance the inside and outside pressure of container.Therefore reach the purpose of automatic adjusting container internal pressure, guaranteed the intensity and the sealing effectiveness of container.
Claims (1)
1, a kind of sealed container interior pressure automatic adjusting device is characterized in that being fastened on hollow breathing device 1 in the nut 3 by hollow bolt 2, plain cushion 4, and the opening part of its breathing device 1 communicates with sealed container interior.
