Specific embodiment
In order that those skilled in the art will better understand the technical solution of the present invention, below with reference to examples and drawings
Product of the present invention is described in further detail.
As shown in Figures 1 to 4, a kind of novel grease proofing ventilative balanced valve, including valve body 1, grease proofing ventilated membrane 2 and protective cover
3, the valve body 1 includes main part 11 and interconnecting piece 12, and the main part 11 is integrally formed with interconnecting piece 12, the main part 11
Equipped with accommodating chamber 13, filter block 4 is equipped in the accommodating chamber 13, the interconnecting piece 12 is equipped with straight-through stomata 14, the straight-through gas
Hole 14 is communicated with accommodating chamber 13, and described 11 one end of main part is equipped with several buckles 15, forms the first through slot between the buckle 15
16, one end that main part 11 is equipped with buckle 15 is arranged in the grease proofing ventilated membrane 2, and the protective cover 3 passes through buckle 15 and main body
Portion 11 connects.Accommodating chamber is arranged by the main part in valve body in the grease proofing ventilative balanced valve of the present invention, and places in accommodating chamber
The features such as filter block, filter block are polymer fiber material, have oleophobic effects good, and Air permenbility is superior, quantity can be one
Or multiple comprehensive uses that are superimposed, straight-through stomata is set in the interconnecting piece of valve body, and pass through the first through slot of main part
It combines with protective cover and circulates to the air pressure inside and outside valve body, keep the structure of grease proofing ventilative balanced valve simple, and make in valve body
Outer air pressure keeps balance, and grease proofing ventilated membrane is arranged on valve body, and glue sticking, soft can be used between grease proofing ventilated membrane and valve body
Glue palette mode, ultrasonic bonding, Vibration welding or hot melt integration fitting, to make grease proofing ventilative balanced valve
Oil preventing performance and balance quality are good.
As shown in Figure 1 and Figure 4, the protective cover 3 is equipped with several grabs 31 for matching with buckle 15, the grab 31 it
Between form the second through slot 32, second through slot 32 is matched with the first through slot 16, and the protective cover 3 passes through buckle 15 and grab
31 are connected together with valve body 1.It is matched by grab with buckle, keeps its structure simple, and be clamped to protective cover and valve body,
Make the first through slot and the second through slot holding one to the first through slot and the second through slot can be U-type groove, round slot etc., to pass through
First through slot and the second through slot circulate to the air pressure of valve body inside and outside, are balanced the air pressure of valve body inside and outside, guarantee grease proofing
The balance quality of ventilative balanced valve.
As shown in Figure 3 or Figure 4, at least two layers of step 17,17 staggered relative of step are equipped in the straight-through stomata 14
Setting, and keep certain distance.Step is arranged to the half size of straight-through stomata, and staggered relative is arranged, and grease proofing will breathe freely
