Description
Technical field
The utility model is related to breather valve field, and in particular to a kind of fair gas recovery type breather valve fire proof construction.
Background technology
Gas recovery type breather valve is permitted to be integrally fixed at the ventilation unit in tank roof, to ensure the normal condition of pressure inside the tank,
Prevent that superpressure or vacuum make storage tank suffer damage in tank, can also reduce pot liquid, oil product evaporating loss.
Chinese patent literature CN204805493U discloses a kind of breather valve, and the breather valve of the patent includes valve body, described
Bonnet is provided with above valve body, the middle part of the valve body has is provided with poly tetrafluoroethylene at the top of valve pocket, the valve body.
In its course of work, due to the oil and water repellent characteristic of polytetrafluoroethylmaterial material itself so that the fluid in valve pocket can be described
Poly tetrafluoroethylene effectively barrier is in valve pocket, it is to avoid fluid is infiltrated into outside valve body, so as to effectively increase the breather valve
Seepage-proof oil ability.
But, the breather valve of above-mentioned patent cannot ensure fire protecting performance.
The content of the invention
The utility model provides a kind of fair gas recovery type breather valve, and the utility model solves existing fair gas recovery type and exhaled
Inhale the problem of valve cannot ensure fire protecting performance.
To solve the above problems, the utility model is adopted the following technical scheme that：Fair gas recovery type breather valve, including valve body,
Bonnet, fire-proof plate and rainhat；Body top is connected by bolt with bonnet, and there is vertical slideway bonnet bosom position；Valve
There are on valve seat, valve seat two valve openings above and below having on the inside of valve port in vivo, two valve openings are respectively communicated with valve inner and valve port；Valve
Internal negative pressure valve disc and malleation valve disc is respectively cooperating with two valve opening upper end surfaces up and down；It is upper in negative pressure valve center hole to fix
There is vertical negative pressure valve disc guide rod, negative pressure valve disc guide rod is engaged with the vertical slideway in bonnet；In positive valve disk center
Vertical malleation valve disc guide rod is fixed with hole, malleation valve disc guide rod and the slide opening at negative pressure valve disc guide rod center coordinate；
Being fixed with valve port external port on fire-proof plate, fire-proof plate has a diameter of 0.3-1 millimeters micropore.Rain-proof is provided with the outside of valve port
Cap, fire-proof plate center is fixed with axle, and rainhat is fixed on axle.
Fair gas recovery type breather valve of the present utility model is when oil-air pressure is more than permission pressure in tank in tank, malleation valve disc
Opened by top, gas escapes identical with atmospheric pressure out of tank.When pressure inside the tank, which is less than, allows pressure, top is opened negative by the air outside tank
It is identical that pressure valve disk enters atmospheric pressure in tank.Fair gas recovery type breather valve of the present utility model is also provided with fire prevention in valve port outer end
Micropore is provided with plate and rainhat, fire-proof plate, micropore plays a part of ventilation.Fire protecting performance is ensure that, it is easy to use.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Symbol description in figure：Valve body 1, bonnet 2, malleation valve disc 3, negative pressure valve disc 4, fire-proof plate 5, rainhat 6, micropore 7, valve
Mouth 8, pilot hole 9, malleation valve disc guide rod 10, negative pressure valve disc guide rod 11.
Embodiment
The utility model is described in detail with optimal embodiment below.
As shown in figure 1, permit gas recovery type breather valve, including valve body 1, bonnet 2, fire-proof plate 5 and rainhat 6；The top of valve body 1
It is connected by bolt with bonnet 2, there is vertical slideway the bosom position of bonnet 2；Being located at the inner side of valve port 8 in valve body 1 has valve seat, valve
Two valve openings above and below having on seat, two valve openings are respectively communicated with the inside of valve body 1 and valve port 8；Negative pressure valve disc 4 and malleation in valve body 1
Valve disc 3 is respectively cooperating with two valve opening upper end surfaces up and down；Vertical negative pressure valve disc is fixed with the centre bore of negative pressure valve disc 4 to lead
To bar 11, negative pressure valve disc guide rod 11 is engaged with the vertical slideway in bonnet 2；It is fixed with the centre bore of malleation valve disc 3 perpendicular
To malleation valve disc guide rod 10, the slide opening at malleation valve disc guide rod 10 and the center of negative pressure valve disc guide rod 11 coordinates；In valve port 8
External port, which is fixed with fire-proof plate 5, fire-proof plate 5, a diameter of 0.3-1 millimeters micropore 7, and micropore 7 plays a part of ventilation.
The outside of valve port 8 is provided with rainhat 6, and the center of fire-proof plate 5 is fixed with axle, and rainhat 6 is fixed on axle.
Fire-proof plate 5 is ca silicate fibre plate, and it is using lime, silicate and inorfil reinforcing material as the plate of primary raw material
Material, the features such as with light weight, intensity high and thermal insulation, good endurance, processing characteristics and excellent workability.
Permit the breathing valve action of gas recovery type：Make full use of the bearing capacity of oil tank in itself to reduce oil vapour discharge, it is former
Reason is the exhaled positive pressure and intake negative-pressure that oil tank is controlled using the weight of valve disc.When the pressure of gas in tank is in mechanical breather valve
Control pressure within the scope of when, breather valve is failure to actuate, keep oil tank seal；When the pressure rise of the gas compartment in tank,
When reaching the control malleation of breather valve, valve disc is pushed up out, and gas is escaped out of tank, makes pressure inside the tank not continue to increase；It is on the contrary
Valve disc declines, and tank is sealed.
Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate the utility model example,
And the not restriction to embodiment.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.And thus
Among the obvious changes or variations amplified out is still in protection domain of the present utility model.
