Tight measure, this requirement are a necessary Xiang Yaoqiu in CE certification, so explosion-proof valve has European patent production at first, afterwards again
Pass to the country, and to being widely applied, however existing explosion-proof valve production use cost is high, mostly disposably makes
With use cost is high, is unfavorable for large-scale popularization.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of waterproof and breathable proposed is let out
Press explosion-proof valve.
To achieve the goals above, the utility model adopts the technical scheme that
The top of a kind of waterproof and breathable pressure-relief anti-explosion valve, including valve body, the valve body is equipped with sealing cover, the sealing
The inner top of lid is fixed with pointed cone, and the side of the sealing cover offers bleeder port, offers spiral on the outside of the valve body
Slot is socketed with sealing ring on the outside of the valve body, and the bottom of the valve body offers small-sized air hole, the valve body
Inner wall is fixed with mounting blocks, and the top of the mounting blocks is equipped with connection ring, and the inside of the connection ring is fixed with waterproof ventilated membrane.
Preferably, the cross section of the valve body is "convex" shaped, and the valve body and sealing cover connection type are mutual
Spiral snapping.
Preferably, the pointed cone is located at the middle part of sealing cover, and the pointed cone is cross pointed cone.
Preferably, the sealing ring is located at the thread root position of helicla flute.
Preferably, the quantity of the small-sized air hole is several, several small-sized air holes are evenly distributed on valve body
Bottom.
Preferably, it is equipped with washer between the mounting blocks and connection ring, passes through bolt between the mounting blocks and connection ring
Connection.
Compared with prior art, the utility model has the beneficial effects that
1, by the way that pointed cone is arranged on sealing cover in the utility model, when waterproof ventilated membrane being enabled to reach certain pressure
It is punctured rapidly, so that quick pressure releasing is realized, so that playing the role of protection is used object.
2, in the utility model by the way that mounting blocks, connection ring and washer are arranged in valve body, enable waterproof ventilated membrane
It is enough easily installed and dismantles, convenient for the replacement of waterproof ventilated membrane.
In conclusion the waterproof and breathable pressure-relief anti-explosion valve will by pointed cone under the pressure that waterproof ventilated membrane reaches certain
It is punctured, and structure is simple, and effect is obvious, has good practicability, while replaceable waterproof ventilated membrane, convenient for promoting.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-4, the top of a kind of waterproof and breathable pressure-relief anti-explosion valve, including valve body 1, valve body 1 is equipped with sealing cover
2, the inner top of sealing cover 2 is fixed with pointed cone 3, and the side of sealing cover 2 offers bleeder port 4, and the outside of valve body 1 offers spiral shell
Spin slot 5, the outside of valve body 1 are socketed with sealing ring 6, and the bottom of valve body 1 offers small-sized air hole 7, the inner wall of valve body 1
Mounting blocks 8 are fixed with, the top of mounting blocks 8 is equipped with connection ring 9, and the inside of connection ring 9 is fixed with waterproof ventilated membrane 10.
The cross section of valve body 1 is "convex" shaped, and valve body 1 and 2 connection type of sealing cover are mutual spiral snapping, pointed cone
3 are located at the middle part of sealing cover 2, and pointed cone 3 is cross pointed cone, and sealing ring 6 is located at the thread root position of helicla flute 5, small-sized
The quantity of stomata 7 is several, several small-sized air holes 7 are evenly distributed on the bottom of valve body 1, mounting blocks 8 and connection ring 9
Between be equipped with washer 11, be bolted between mounting blocks 8 and connection ring 9.
