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 alleviates device, including passage and is arranged in passage and is used for indoor negative pressure
The autocontrol valve of alleviation.
Passage is arranged on the wall between indoor and outdoor, and for the space inside and outside communication chamber.
Include swingle 4, valve plates 2 and ballast bar 3 for the autocontrol valve that indoor negative pressure is alleviated.The swingle 4
It is horizontally set in the passage inside and outside communication chamber.The middle part of the valve plates 2 is hinged and connected on swingle 4, makes the middle part of valve plates 2
It can be rotated freely along swingle 4.Ballast bar 3 is arranged at the lower section in valve plates 2, under the Action of Gravity Field of ballast bar 3, valve plates
2 be in vertical original state and the closing passage of state lower valve door-plate 2.
Wherein, the closing passage of valve plates 2 is not fully sealed, the diameter of valve plates 2 2-3mm small than channel internal diameter, valve
Plate 2 is conducted oneself with dignity more light better.
Specifically, the passage is formed by the inner chamber of the pipeline 1 of a both ends open, the material requirements of pipeline 1 is indeformable, optional
Use PVC plastic material.Pipeline 1 is used on the wall between indoor and outdoor and through the wall.The two ends difference of the swingle 4
On the inwall at the radial direction two ends of connecting pipe 1.
The present apparatus also includes one and resets blend stop 5, resets blend stop 5 and is arranged on the inwall below pipeline, and the reset blend stop 5
It is in contact with the valve plates 2 under original state, while the indoor side of the valve plates 2 under original state.So, interior is worked as
When producing negative pressure, the latter half of valve plates 2 can not inwardly rotate due to resetting the barrier effect of blend stop 5, can only valve plates 2
Top half can inwardly rotate, and thereby may be ensured that the smooth opening passage of valve plates 2.
As the preferred exemplary of the present invention, passage is located at the part on the wall between indoor and outdoor to extend laterally, shape
Into first passage 7, the part that passage is located outside is extended downwardly, and forms second channel 8, Open Side Down for second channel 8.Second
The wind that Open Side Down is conducive to stop outdoor of passage 8 is got in by valve.Advantageously, separation net 6 is provided with opening, it is outdoor
Separation net 6 block the entrance of outdoor impurity.
As presently preferred example, as shown in figure 4, second channel 8 and the junction inner upper of first passage 7
With interior curved first surface 9.There is the second curved surface 10 of evagination between first surface 9 and valve plates 2.Meanwhile, valve plates 2
Top half offers a via hole (not shown).The special channel design is particularly suitable for use in as Water reservoir water draining hole management house
The situation of this indoor easily burst negative pressure.In this case, negative pressure is instantaneously transferred to management house, it is desirable to which valve plates 2 can be fast
Speed is reacted, and opens passage.Its course of work is, during indoor generation burst negative pressure, and high pressure draught meeting moment is first by via hole
Into so that moment, which drives, produces substantial amounts of air-flow in second channel 8 and first passage 7, substantial amounts of air-flow passes through first surface 9
When produce tangential centrifugal force, air-flow is concentrated on the top of second channel 8, then through wall attachment effect of second curved surface 10 to air-flow,
So that air-flow blows to the upper end-face edge of valve plates 2 along the second curved surface 10, valve plates 2 are opened so as to quick.After opening, air-flow can
Interior is rapidly entered, until indoor negative pressure is alleviated.
Invention additionally provides a kind of Water reservoir water draining hole management house, run through on the wall of the management house and be provided with least one
Above-mentioned indoor negative pressure alleviates device.Gate falls too fast, the larger negative pressure produced suddenly when the device can avoid the drainage tunnel from discharging water
The destruction caused to management house, is a kind of automatics for alleviating negative pressure in management house.The present apparatus is arranged on the wall of management house
In, through wall, be provided with an autocontrol valve in inner side, when there is negative pressure generation, control valve can be automatically opened up, and make outdoor
Pressure plays a part of alleviating indoor negative pressure automatically into interior；When indoor external pressure is close to balance, control valve can be automatic
Close, play a part of to management house insulation.
Although an embodiment of the present invention has been shown and described, it will be understood by those skilled in the art that：Not
In the case of departing from the principle and objective of the present invention a variety of change, modification, replacement and modification can be carried out to these case study on implementation,
The scope of the present invention is limited by claim and its equivalent.
