Embodiment
Referring to the embodiment of the present invention, the invention will be further described.
As Figure 1-3, a kind of indoor negative pressure relieving apparatus, comprises passage and is arranged at the autocontrol valve alleviated for indoor negative pressure in passage.
On the wall of channel setting between indoor and outdoor, and for the space inside and outside communication chamber.
The autocontrol valve alleviated for indoor negative pressure comprises swingle 4, valve plates 2 and ballast bar 3.This swingle 4 is horizontally set in the passage inside and outside communication chamber.The middle part of this valve plates 2 is hinged and connected on swingle 4, and the middle part of valve plates 2 can be rotated freely along swingle 4.Ballast bar 3 is arranged at the below in valve plates 2, and under ballast bar 3 Action of Gravity Field, valve plates 2 is vertical original state and this state lower valve plate 2 closing passage.
Wherein, valve plates 2 closing passage non-fully sealing, the little 2-3mm of the comparable channel internal diameter of valve plates 2 diameter, valve plates 2 is conducted oneself with dignity more light better.
Concrete, this passage is formed by the inner chamber of the pipeline 1 of a both ends open, and this pipeline 1 material requirements is indeformable, can select PVC plastic material.Pipeline 1 is for be arranged on the wall between indoor and outdoor and to run through this wall.On the inwall at the difference radial two ends of connecting tube 1, two ends of described swingle 4.
This device also comprises a reset blend stop 5, and reset blend stop 5 is arranged on the inwall below pipeline, and this reset blend stop 5 contacts with the valve plates 2 under original state, is positioned at the indoor side of the valve plates 2 under original state simultaneously.Like this, when indoor generation negative pressure, valve plates 2 lower half portion can not inwardly rotate due to the barrier effect of reset blend stop 5, upper half part of valve plates 2 inwardly can only can rotate, thus can ensure valve plates 2 smooth opening passage.
As a preferred exemplary of the present invention, the part on the wall of passage between indoor and outdoor is horizontal expansion, forms first passage 7, and passage is positioned at outdoor part to downward-extension, and form second channel 8, Open Side Down for second channel 8.Second channel 8 wind that Open Side Down is conducive to stop outdoor enters indoor by valve.Advantageously, opening is provided with isolation net 6, and outdoor isolation net 6 blocks entering of outdoor impurity.
As another preferred exemplary of the present invention, as shown in Figure 4, second channel 8 and first passage 7 joint inner upper have interior curved first surface 9.There is between first surface 9 and valve plates 2 second curved surface 10 of evagination.Meanwhile, upper half part of valve plates 2 offers a via hole (not shown).This special channel design is specially adapted to easily to happen suddenly as this indoor of Water reservoir water draining hole management house the situation of negative pressure.In this case, negative pressure is delivered to management house instantaneously, requires that valve plates 2 can be reacted fast, opens passage.Its working procedure is, during indoor generation burst negative pressure, high pressure air fails to be convened for lack of a quorum and is first entered by via hole instantaneously, thus drive the air-flow that in second channel 8 and first passage 7, generation is a large amount of instantaneously, a large amount of air-flows produces tangential centrifugal force when first surface 9, makes air-flow concentrate on the top of second channel 8, then through the wall attachment effect of the second curved surface 10 pairs of air-flows, make air-flow blow to valve plates 2 upper end-face edge along the second curved surface 10, thus valve plates 2 can be opened fast.After opening, air-flow can enter indoor fast, until indoor negative pressure is alleviated.
Invention additionally provides a kind of Water reservoir water draining hole management house, the body of wall of this management house runs through and is provided with at least one above-mentioned indoor negative pressure relieving apparatus.When this device can avoid drainage tunnel to discharge water, gate falls too fast, the destruction that the larger negative pressure produced suddenly causes management house, is a kind of robot device alleviating negative pressure in management house.This device is arranged in the body of wall of management house, runs through body of wall, is provided with an autocontrol valve in inner side, and when there being negative pressure to produce, control valve can be opened automatically, makes pressure outside automatically enter indoor, plays the effect alleviating indoor negative pressure; When indoor and outdoor pressure is close to balance, control valve can be closed automatically, plays the effect to management house insulation.
Although illustrate and describe embodiments of the invention, those having ordinary skill in the art will appreciate that: can carry out multiple change, amendment, replacement and modification to these case study on implementation when not departing from principle of the present invention and aim, scope of the present invention is by claim and equivalents thereof.
