The invention discloses a breather valve. The breather valve comprises an upper valve cover, a lower valve cover and a valve body; the upper valve cover and the lower valve cover are arranged at the upper end and the lower end of the valve body respectively; the upper valve cover is provided with a water outlet; the lower end of the water outlet is provided with a sealing ring; the lower valve cover is provided with a water inlet; the water inlet protrudes the inner surface of the lower valve cover to form a plurality of balance holes; the lower end surface of the water inlet is provided with a sealing cover; a piston is arranged in the valve body; the piston is provided with a buoyancy ring; the surface of the buoyancy ring is provided with a plurality of water holes; a hydraulic device is arranged between the buoyancy ring and the upper valve cover; a plurality of pressure sensors are uniformly distributed on the lower surface of the buoyancy ring. The breather valve is provided with a leakage-proof device, a tank opening can be blocked through the leakage-proof device when a tank rolls over to prevent the liquid from flowing out of the breather valve, and accordingly the economic loss of people can be avoided and the environment-friendly effect is achieved.
Description
Technical field
The present invention relates to a kind of device maintaining pressure in fuel tank, particularly relate to a kind of breathing valve.
Background technology
Breathing valve is made up of pressure valve and vacuum valve, be installed on cargo oil tank permeability cell, can change and automatic open close with oil gas positive/negative-pressure in cargo oil tank, make the poor valve remained within the scope of permissible value of cargo oil tank inner and outer air pressure, oil tank truck is in injection, release liquid or because of internal liquid phase mutual friction when car moves, produce larger pressure, or evaporate situations such as making its internal pressure minimizing time, need to make tank body or mutually ventilate between internal tank and ambient atmosphere, ensure that tank body or container internal pressure meet tank body or Vessel Design force value, prevent tank body or container pressure too low and take out flat or hypertonia and the phenomenon that bursts occurs, usually on the tank body or container of accumulating liquid, breathing valve is installed, breathing valve is arranged on the top of tank body or container.
But although breathing valve can effectively solve the problem, just in case car has an accident during rollover, liquid easily flows out from breathing valve, causes heavy economic losses, and serious environment pollution.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of breathing valve.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of breathing valve, comprising: bonnet, bottom flange and valve body, and described bonnet, and described bottom flange are arranged on the two ends up and down of described valve body respectively;
Described bonnet, offers a water outlet, described water outlet lower end is provided with seal ring;
Described bottom flange offers a water inlet, described water inlet protrudes described bottom flange inside face opens some balance hole, and described water inlet lower surface is provided with a seal cover cap;
Be provided with a piston in described valve body, described piston is provided with buoyancy ring, described buoyancy ring surface offers some water holes, is provided with a hydraulic efficiency gear between described buoyancy ring and described bonnet, and described buoyancy ring lower surface distributes some pressure inductors uniformly.
In a preferred embodiment of the present invention, described hydraulic efficiency gear, to be connected by electric wire between described seal cover cap and described pressure inductor.
In a preferred embodiment of the present invention, the diameter 0.01mm less of the internal diameter of described valve body of described buoyancy ring.
The invention has the beneficial effects as follows: a kind of breathing valve of the present invention, this breathing valve is provided with leak-proof device, when rollover occurs jar; tank mouth can be blocked by leak-proof device; prevent liquid from flowing out from breathing valve, not only make the economy of people from loss, and protect environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of breathing valve of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, bonnet; 2, bottom flange; 3, valve body; 4, water outlet; 5, seal ring; 6, water inlet; 7, balance hole; 8, seal cover cap; 9, piston; 10, buoyancy ring; 11, water hole; 12, hydraulic efficiency gear; 13, pressure inductor.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises: a kind of breathing valve, comprising: bonnet, 1, bottom flange 2 and valve body 3, and described bonnet, 1 and described bottom flange 2 are arranged on the two ends up and down of described valve body 3 respectively, and these three parts form the main body of this breathing valve.
Described bonnet, 1 offers a water outlet 4, described water outlet 4 lower end is provided with seal ring 5, and described seal ring 5 makes described water outlet 4 be connected more tight with the upper end of described piston 9.
Described bottom flange 2 offers a water inlet 6, described water inlet 6 protrudes described bottom flange 2 inside face opens some balance hole 7, and described balance hole 7 can, when described water outlet 4 is by sealing, make described valve body 3 inside be in communication with the outside.
Described water inlet 6 lower surface is provided with a seal cover cap 8, and described seal cover cap 8 serves the effect of the closed described water inlet 6 when oil tank is turned on one's side.
Be provided with a piston 9 in described valve body 3, between described valve body 3 and described piston 9, form the circulation that an inner chamber is used for smuggled goods air.
Described piston 9 is provided with buoyancy ring 10, and described buoyancy ring 10 surface offers some water holes 11, and described water hole 11 makes water and air can circulate in described valve body 3.
One hydraulic efficiency gear 12 being installed between described buoyancy ring 10 and described bonnet, 1, when described hydraulic efficiency gear 12 is for turning on one's side, described piston 9 being pressed down closed described water inlet 6.
Described buoyancy ring 10 lower surface distributes some pressure inductors 13 uniformly, and described pressure inductor 13 is for the induction to pressure.
Described hydraulic efficiency gear 12, to be connected by electric wire between described seal cover cap 8 and described pressure inductor 13, described in each, the pressure of pressure inductor 13 should be identical at ordinary times, when turning on one's side, the pressure of each described pressure inductor 13 is different, now described hydraulic efficiency gear 12 promotes described buoyancy ring 10 described water inlet 6 is sealed by described piston 9, now described seal cover cap 8 is closed, the lower end of described water inlet 6 is sealed, thus avoids the liquid in tank or gas to expose.
The diameter 0.01mm less of the internal diameter of described valve body 3 of described buoyancy ring 10, makes described piston 9 be free to move up and down in described valve body 3.
Compared with prior art, a kind of breathing valve of the present invention, this breathing valve is provided with leak-proof device, and when rollover occurs jar, tank mouth can be blocked by leak-proof device, prevents liquid from flowing out from breathing valve, not only makes the economy of people from loss, and protects environment.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
