Description
Technical field
The present invention relates to a kind of cumulative photovoltaic generation module vent valve, specifically a kind of waterproof vent valve for balancing cumulative photovoltaic generation module inner and outer air pressure.
Background technique
Cumulative photovoltaic generation widely uses waterproof vent valve, and for balancing ambient temperature (four seasons, round the clock weather) change, in the sealing module that causes, air expands with heat and contract with cold the pressure change caused.At present, the waterproof vent valve of use has waterproof and dustproof, ventilate function, and its structure is by plastic cement or metal shell and waterproof ventilated membrane welds or pressing forms, and its safeguard function and Air permenbility depend on the function of waterproof ventilated membrane, quality and work area.
Along with the development of photovoltaic cause, also some technical problems have been there are, if cumulative photovoltaic generation module is after installing and using a period of time, there is lens glass projection and depressed phenomenon, and the normal work of impact, M R of having to carry out, trace it to its cause, be largely because the ventilated membrane area dirt of waterproof vent valve have impact on gas permeability, the Air permenbility of waterproof vent valve reduced, can not comparatively fast balance caused by module inner and outer air pressure.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of waterproof vent valve that can realize overpressure protection and automatic dust removing.
In order to solve the problems of the technologies described above, waterproof vent valve of the present invention, comprise valve body and be arranged on the valve gap on valve body, there is in valve body the chamber for installing the valve block being welded with ventilated membrane, air-flow path is formed between valve block and the inwall of valve body. be also provided with the upper lip silica gel sealing ring extend in chamber in valve body, the top lip of seal ring is pressed over the bottom of valve block, the top of valve block is mounted with elastic component, described elastic component is crushed between valve block and valve gap, if any over-pressure gas in chamber, and overcome the elastic force of elastic component, valve block can be promoted by over-pressure gas and then make over-pressure gas enter air-flow path to discharge.
Described valve block is plastic cement skeleton, and described ventilated membrane is welded on plastic cement skeleton.
Described seal ring is upper lip silica gel sealing ring.
Described elastic component is jump ring, and described jump ring has inner ring and outer shroud, described inner ring is provided with multiple profile of tooth shell fragment, described outer shroud is provided with multiple opening.
Be provided with the slot for installing seal ring in described valve body, described seal ring is placed in slot.
Described valve gap is provided with the tip extend in placing chamber, described elastic component by tip pressure holding on valve block.
After adopting above-mentioned structure; due to the valve block being provided with ventilated membrane arranged; the seal ring coordinated with valve block and elastic component and the air-flow path be formed between valve block and body wall; normally can be exhausted by ventilated membrane thus; when external pressure in balance module can not have been met by waterproof ventilated membrane exhaust separately; in module, pressure increases; when exceeding setting pressure; valve block can be promoted by over-pressure gas thus make over-pressure gas enter air-flow path and puff prot is discharged, and thus achieves overpressure protection and automatic dedusting function.
Accompanying drawing explanation
Fig. 1 is the structural representation of waterproof vent valve of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, waterproof vent valve of the present invention is described in further detail.
As shown in the figure, waterproof vent valve of the present invention, comprise valve body 1 and be arranged on the valve gap 6 on valve body, there is in valve body 1 chamber 7 for installing movable valve plate 3, valve block 3 is formed by waterproof ventilated membrane and plastic cement frame welding, air-flow path 9 is formed between valve block 3 and the inwall of valve body, by valve block 3 and ventilated membrane 5, chamber is divided into upper and lower two-part thus, also be provided with its top in valve body 1 and extend into seal ring 2 in chamber, said seal ring 2 is upper lip silica gel sealing ring, as seen from Figure 1, the slot for installing seal ring 2 is provided with in valve body, seal ring 2 is placed in slot, sealing circle has tip, the tip of seal ring 2 is pressed over the bottom of valve block 3, the top of valve block 3 is mounted with elastic component 8, specifically, valve gap 6 is provided with the tip extend in chamber, elastic component by tip pressure holding on valve block, elastic component 8 is made to be crushed between valve block 3 and valve gap 6 thus, by such structure make valve block 3 become one can be movable independently unit, valve block and valve body realize sealing through upper lip silica gel sealing ring, make easily to seal between valve block 3 and valve body 1, also easily open, when there being over-pressure gas in chamber, valve block can be promoted by over-pressure gas, and then make over-pressure gas enter air-flow path discharge.
Further, valve block 3 of the present invention is plastic cement skeleton, ventilated membrane 5 is welded on plastic cement skeleton, formed one can be movable separate unit, when elastic component is spring, valve body height can be increased considerably, there is drawback, therefore the elastic component 8 in the present embodiment is preferably jump ring, through jump ring, pressure is applied with to valve block after being locked by valve gap and valve body pressing, to reach the sealing with valve body, said jump ring includes inner ring and outer shroud, inner ring is provided with multiple profile of tooth shell fragment, outer shroud is provided with multiple opening, the nip portion of jump ring outer shroud and valve gap is made to define multiple gap thus, serve the effect of puff prot.
Its working principle and working procedure as follows:
When the cumulative photovoltaic generation module being provided with waterproof vent valve in outdoor along with the rising of temperature, air in module starts to expand and forms interior pressure, the air that now part has more externally can be discharged by the waterproof ventilated membrane that valve block is installed, when temperature continues to raise, and when heating up very fast, in module, air expands and accelerates, so that when can not meet external pressure in balance module by waterproof ventilated membrane exhaust separately, module inner air pressure progressively increases, when interior pressure increases to the safety protection air pressure of setting, valve block is by superpressure air push, upper lip silica gel sealing ring loses seal action, superpressure air is externally vented from waterproof ventilated membrane and the preset clearance between valve body and valve block (air-flow path) simultaneously, and this part air of discharging is through valve gap, the multiple gaps formed after multiple opening of jump ring outer-loop and the outer pressing of valve block top form the air-flow that multiply has certain wind speed, add that the air stream of discharging from waterproof ventilated membrane is formed mixed disturb air-flow or cyclone thus make to realize from dedusting function.
