Abstract
A relief valve structure with a relief gap mainly includes a tubular body, and an elastic plug body which is closely adhered to the wall of the tubular pipe; the elastic plug body is provided with a slim gap. When the liquid flows from the tubular body to the elastic plug body and the impact pressure brought by the liquid is larger than when the thin gap of the elastic plug can bear, the interconnecting place along the thin gap may be deformed to form a hole; thus the liquid can flows through the elastic plug body, reaching the purpose of relieving the pressure.
Description
Technical field
The utility model refers to have the pressure-relief valve structure of pressure release slot especially about a kind of pressure-relief valve structure.
Background technique
Now three kinds of thermoelectricity, water power, nuclear powers etc. can be arranged with the electric power of industrial-scale production, and be described as the fuel cell power generation of the 4th kind of electric power, also developed countries such as U.S., day emerge, and entering at a quick pace with the impetus of rousing oneself to catch up can be with the ranks of commercial scale generating.
Fuel cell is the battery that a kind of chemical energy changes into electric energy, and the energy that it mainly utilizes material to be disengaged when chemical reaction takes place directly is transformed to electric energy with it.Compare with other chemical cell such as manganese dry cell, lead storage battery, fuel cell needs to supply with active material (material that reacts)--fuel and oxygenant to it continuously when work, so fuel cell is different with other general chemistry battery.
With direct methanol fuel cell, fluid such as methanol aqueous solution and air can be in the internal flow of direct methanol fuel cell, simultaneously, direct methanol fuel cell after electrochemical reaction biological carbon dioxide and water or other fluid also can flow outward in the inside of direct methanol fuel cell.Therefore, if take place unusually when excessive when the internal pressure of direct methanol fuel cell, at this moment, above-mentioned fluid can produce the flow phenomenon of unexpected property.Therefore, if direct methanol fuel cell is not provided with pressure relief mechanism, the as easy as rolling off a log damage that is directed at direct methanol fuel cell.
See also Figure 1A～1B, Figure 1A～1B is the schematic representation of known pressure-relief valve structure.Shown in Figure 1A～1B, it is No. 369098 patent in Taiwan " the adjusting structure of air pressure ".Shown in Figure 1A, when entering via suction port as if pressurized gas, the impact force that it brought will push ball 3.Shown in Figure 1B, if this impact force when propping up the elastic component 41 of ball 3, was originally blocked the ball 3 of air input part 200, will no longer continue to block, and make these pressurized gas flow to the portion 22 of losing heart, and pressurized gas are discharged from along the direction of arrow 5.
Yet, elastic component 41 in " the adjusting structure of air pressure " belongs to metal material, therefore if directly be applied on the pressure release function of fuel cell, the long-term corrosion elastic component 41 easily that uses, make elastic component 41 lose the effect that originally props up ball 3, and then make whole Decompression valves ineffective.
The model utility content
Main purpose of the present utility model is to provide a kind of pressure-relief valve structure with pressure release slot, by the finedraw that is arranged in the elasticity cock body, can during greater than the material characteristic, make finedraw become hole at pressure, and then discharge high-pressure liquid.
Based on above-mentioned purpose, the utlity model has the pressure-relief valve structure of pressure release slot, mainly comprise tubular body, the complete close attachment in its edge in the elasticity cock body of tubular body wall, and the elasticity cock body is equipped with finedraw.When fluid flows to the elasticity cock body via tubular body, and the percussive pressure that fluid brought be can resist greater than the finedraw of elasticity cock body the time, the hole of the confluce of this finedraw for fluid is passed through; When fluid no longer flows to the elasticity cock body via tubular body, the finedraw of this hole for fluid is passed through.And then reach the purpose of pressure release.
Can be about concrete structure of the present utility model by following detailed description and appended graphic being further understood.

Embodiment
See also Fig. 2 A～2B, be the not pressure release schematic representation of the pressure-relief valve structure that the utlity model has the pressure release slot.Shown in Fig. 2 A～2B, the utlity model has the pressure-relief valve structure 25 of pressure release slot, mainly by tubular body 30, elasticity cock body 32 and the pressure release finedraw 34 that is arranged in elasticity cock body 32.Tubular body 30 shown in Fig. 2 B is a kind of example, and unrestricted the utility model can only use the tubular body 30 of this kind shape.
In the pressure-relief valve structure 25 that the utlity model has the pressure release slot, the elasticity cock body 32 that elastic material constituted, the complete close attachment in its edge is in the tube wall of tubular body 30.Be to form pressure release finedraw 34, can draw by sharp sword according to predetermined figure and wear elasticity cock body 32 and form.Just, the pattern of finedraw 34 also can be trident, rice word or other kenel finedraw except the cross shown in Fig. 2 A.
See also Fig. 3 A～3B, be the pressure release schematic representation of the pressure-relief valve structure that the utlity model has the pressure release slot.Shown in Fig. 3 A～3B, the utlity model has the pressure-relief valve structure 25 of pressure release slot, still mainly constituted by tubular body 30, elasticity cock body 32, just can form hole 36 because of the percussive pressure that fluid brought.
Specifically, when fluid flows to elasticity cock body 32 via tubular body 30, and when the percussive pressure that fluid brought can be resisted greater than 34 of the finedraws of elasticity cock body 32, confluce along finedraw 34 may be deformed to hole 36, and makes fluid pass through elasticity cock body 32 and flow to the portion 22 of losing heart along the direction of arrow 38.
If when fluid no longer flows to elasticity cock body 32 via tubular body 30, hole 36 as shown in Figure 3A can revert to the finedraw 34 shown in Fig. 2 A, and makes fluid no longer by elasticity cock body 32.
In sum, in the pressure-relief valve structure 25 that the utlity model has the pressure release slot, only can be when surpassing 32 percussive pressure that can resist of elasticity cock body, just can become hole 36 and allow fluid pass through, reach the purpose of pressure release, and utilize elasticity cock body 32 materials own can elastic return characteristic, and do not allow fluid pass through in normal condition.
The utility model pressure-relief valve structure 25 is to be specially adapted to fuel cell, and because the structural factor of pressure-relief valve structure 25 makes so, make miniaturization or microminiaturized Decompression valves to realize, this provides remarkable contribution for the fuel cell of fuel cell being carried out into miniaturization or microminiaturization, and this is the utility model advantage and effect is promoted the place.
By the above detailed description of preferred embodiments, hope can be known description feature of the present utility model and spirit more, and is not to come category of the present utility model is limited with above-mentioned disclosed preferred embodiment.On the contrary, its objective is that hope can contain in the category of the claim that is arranged in the desire application of the utility model institute of various changes and tool equality.
