Description
Technical field
The present invention relates to balanced valve technical field, the ventilative balance of specially a kind of splashproof oleophobic applied to leakproof fuel cell
Valve.
Background technology
The draught head that would generally be used at present on the fuel tank of motor vehicle using balanced valve inside and outside trim tank, conventional is flat
Weighing apparatus valve generally comprises primary body, gland and ventilated membrane, and the body interior is provided with straight-through stomata, and gland is pressed together on the one of main body
End, ventilated membrane is arranged in the straight-through stomata of body interior, and the structure of this balanced valve is relatively simple, can also realize in fuel tank
Outer air pressure balance, still, because motor vehicle is often occurring that some jolt using during, makes the fluid in fuel tank
Easily it is fed directly in the straight-through stomata of main body, due to the structure for not having to stop fluid in balanced valve, and ventilated membrane is general
All it is that, using commonly conventional ventilated membrane, the oil preventing performance of common ventilated membrane is poor, the readily permeable ventilated membrane of fluid, so as to hold
Easily there is oil leak and the generation of permeability phenomenon, influence the performance of balanced valve.
The content of the invention
The invention provides a kind of simple in construction, cost is low, oil preventing performance is good, good airproof performance and easy to use it is applied to
The ventilative balanced valve of the splashproof oleophobic of leakproof fuel cell.
The present invention can be achieved through the following technical solutions：
A kind of splashproof oleophobic applied to leakproof fuel cell is breathed freely balanced valve, including splashproof oleophobic main body, splashproof oleophobic gland and anti-
Provided with straight-through stomata in the middle part of oily ventilated membrane, the splashproof oleophobic main body, the splashproof oleophobic gland is pressed together on splashproof oleophobic main body
One end on, the grease proofing ventilated membrane is arranged in straight-through stomata, the splashproof oleophobic gland be provided with gland air-vent, it is described
Filter block is provided with the straight-through stomata of the splashproof oleophobic main body other end, it is saturating provided with flowing backwards between the filter block and grease proofing ventilated membrane
Gas, the refluence ventilation body is in funnel-form, and its large port is set towards splashproof oleophobic gland direction, on the refluence ventilation body
Provided with the passage for circulated gases.The present invention breathes freely balanced valve mainly including splashproof applied to the splashproof oleophobic of leakproof fuel cell
Oleophobic main body, splashproof oleophobic gland, grease proofing ventilated membrane, filter block and refluence ventilation body, its constituent parts are few, simple in construction；
The splashproof oleophobic main body, splashproof oleophobic gland, filter block and refluence ventilation body can be made of conventional metal material,
Its abundance, with low cost, the grease proofing ventilated membrane can be using conventional grease-proof and waterproof ventilated membrane, and the grease-proof and waterproof is saturating
Air film is conventional parts, and its cost is relatively low.The present invention passes through the straight-through stomata of splashproof oleophobic main body and splashproof oleophobic gland
Gland air-vent realizes that the circulation of gas is exchanged, and keeps the air pressure balance inside and outside fuel tank；Provided with a number of in the filter block
