Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with embodiment and accompanying drawing, this utility model product is described in further detail.
As Fig. 1 shows, the utility model discloses a kind of pressure explosion-proof pressure release balanced valve applying compact battery bag, including explosion-proof valve main body 2, described explosion-proof valve main body 2 is hub-type frame structure 21, described hub-type frame structure 21 is internal is provided with clear opening stacked stop transverse slat structure 22, described stop transverse slat structure 22 side is provided with protection steel disc 4, described protection steel disc 4 inside is the ventilative clear opening structure of circular hole and circular arc type, it is fitted with waterproof ventilated membrane 3 between described explosion-proof valve main body 2 and described protection, the hub-type framework inwall of described explosion-proof valve main body 2 fastens sealing strip 5, the hub-type framework outer wall of described explosion-proof valve main body 2 fastens Explosion-proof cap 1.The plastic casing of the described integrated injection mo(u)lding of explosion-proof valve main body 2, described waterproof ventilated membrane 3 uses hot melten type integrated molding to be fitted in the inwall of described explosion-proof valve main body 2.The position of described waterproof ventilated membrane 3 laminating is simultaneously relative with the ventilative clear opening structure of the stop transverse slat structure 22 of described explosion-proof valve main body 2, protection steel disc 4.Described waterproof ventilated membrane 3 is e-PTFE material film.Described explosion-proof valve main body 2 is fixed-type by hot melt pin deck 6 with described protection steel disc 4.The outer wall of described Explosion-proof cap 1 is provided with boss 11 fixed structure, and described boss 11 structure is relative with described stop transverse slat structure 22.Described explosion-proof valve main body 2 is arc surface type structure in the hub-type framework of described Explosion-proof cap 1 activity button-fold.The assembly method of described pressure explosion-proof pressure release balanced valve is: first assembled with the mode that explosion-proof valve main body 2 uses button bit to press by Explosion-proof cap 1, secondly explosion-proof ventilated membrane is welded, the formula that is then inserted into fastens sealing strip 5, finally uses the mode of thermal welding to weld protection steel disc 4.
In pressure explosion-proof pressure release balanced valve of the present utility model, Explosion-proof cap 1 uses arc surface type general frame pattern and overall dimensions size as explosion-proof valve main body 2 overall dimensions, and its effect is so that pressure explosion-proof pressure release balanced valve anti-layer IPX grade when the state of use improves；Explosion-proof valve main body 2 uses surrounding side and starts straight-through ventilative mode, and its effect is the first-pass yield effect after increasing its explosion by current pressure explosion-proof pressure release balanced valve field and rate of the covering problem reducing work condition state earth；Explosion-proof ventilated membrane its can play water proof and dust proof and enter on the another side of film material and with the effect of piercing function；Steel disc mainly plays, with its effect of ventilative clear opening structural style of circular hole and circular arc type, the effect that protection is ventilative；Sealing strip 5 coordinates fixing seal to install with the press-in of surrounding interference post, and its effect is that installation is simple to operate the most just；Sealing strip 5 is that integrated injection forming plays, to explosion-proof valve main body 2, the effect that installation is fixing.
In pressure explosion-proof pressure release balanced valve of the present utility model; it act as at the position, upside of explosion-proof valve main body 2 to withhold its protection cap structure of installation in Explosion-proof cap 1 is consistent with explosion-proof valve main body 2 outer wheel hub: one mainly reduces the vapor permeation area structure of the straight-through probability above Explosion-proof cap 1, thus increases the anti-layer grade effect of this product；Two mainly to use explosion-proof valve main body 2 structure position surrounding straight-through ventilative for it, inside is provided with clear opening stacked stop transverse slat structure 22, act on the effect of dust-proof grade considering that design, explosion-proof valve main body 2 and waterproof ventilated membrane 3 use integral hot melting its Main Function of moulding process mode is to allow rupture pressure disc material and plastic casing sealing moulding be integrated explosion-proof valve main body 2 use hot melt pin deck 6 fixed form with protection steel disc 4 and fasten its effect mainly fixed protection steel disc 4 and explosion-proof valve main body 2 main body；Explosion-proof valve main body 2 and sealing strip 5 use spacing fixed draw-in groove by compressing into installation, and the effect of its two parts is that the air-tightness function explosion-proof valve main body 2 playing sealed product uses integrated injection forming mode with hot melt pin deck 6 and uses protection steel disc 4 to be fixed in described explosion-proof valve main body 2.
Operation principle and effect be: (1) PACK is when nominal situation running status, owing to PACK in use produces corresponding temperature rise because of change and the internal component work of geographical environment, thus produce corresponding pressure, certain pressure differential is formed with outside, so far pressure explosion-proof pressure release balanced valve of the present utility model is loaded onto, by the effect of explosion-proof ventilated membrane, the pressure within seal casinghousing can be excreted to external environment condition, it is achieved with the effect of external pressure balance.PACA is when occurring extremely or exploding duty, owing to inner sealing cavity is in sealing state, a great pressure action can be produced in internal moment and and cause destruction and the degradation problem under service life of internal component on the inwall of seal casinghousing, so far pressure explosion-proof pressure release balanced valve of the present utility model is loaded onto, after Pack occurs that appeal is abnormal, the function of pressure release rapidly can be carried out by the way of straight-through with outside air by puncturing of effect and explosion-proof ventilated membrane and explosion-proof valve main body 2, thus meet the pressure of supercharging rapidly with relatively short period of time and discharge with excretion.(3) when operating mode and abnormality, in order to protect in the situation grieshoch used and the intrusion of solidifying soil, use closing half stacking exploitation formula structure design and can effectively avoid the probability of above-mentioned generation and improve service life.
The above, preferred embodiment the most of the present utility model, not this utility model is made any pro forma restriction；The those of ordinary skill of all industry all can shown in by specification accompanying drawing and the above and implement this utility model swimmingly；But, all those skilled in the art in the range of without departing from technical solutions of the utility model, available disclosed above technology contents and a little change made, the equivalent variations modifying and develop, be Equivalent embodiments of the present utility model；Meanwhile, all any equivalent variations above example made according to substantial technological of the present utility model change, modify and differentiation etc., within all still falling within the protection domain of the technical solution of the utility model.
