Abstract
The utility model discloses a kind of breather valve, including housing, housing upper end is arranged with top cap, side, top cap lower end is fastenedly connected by bolt with housing, ventilation mouth it is provided with between opposite side and housing, housing upper end is provided with flap of giving vent to anger, flap upper end of giving vent to anger is provided with valve rod, spring it is arranged with on valve rod, spring is in top cap and gives vent to anger between flap, valve rod lower end is through giving vent to anger flap, and connection has screw rod, screw rod upper end is fixing with valve rod to be connected, lower end passes through the air inlet flap in housing, and carry out spacing cooperation by nut, flap lower end of giving vent to anger is provided with seal washer, fit with air outlet valve flap seal in seal washer upper end, lower end and housing and the laminating of intake valve flap seal, flap of giving vent to anger is provided with passage.This utility model moment maintains cartridge gas pressure balance, and during superpressure, in tank, gas overflows tank internal gas pressure not in rising from this；During low pressure, air is not reducing thence into tank body tank internal gas pressure, it is ensured that storage tank will not wreck because air pressure is uneven.
Description
Technical field
This utility model relates to a kind of breather valve, belongs to oil truck accessory technical field.
Background technology
For guaranteeing that storage tank exempts from destruction when superpressure or vacuum, reducing the service life of storage tank, storage tank needs one to tie up
Hold the safety devices of cartridge gas pressure balance.
Utility model content
For the problems referred to above, this utility model provides a kind of breather valve, it is therefore intended that the moment maintains cartridge gas pressure balance,
During superpressure, in tank, gas overflows tank internal gas pressure not in rising from this；During low pressure, air is not dropping thence into tank body tank internal gas pressure
Low, it is ensured that storage tank will not wreck because air pressure is uneven.
The purpose of this utility model is achieved through the following channels:
A kind of breather valve, including housing, described housing upper end is arranged with top cap, and side, described top cap lower end is passed through with housing
Bolt is fastenedly connected, and is provided with ventilation mouth between opposite side and housing, and described housing upper end is provided with flap of giving vent to anger, described in give vent to anger
Flap upper end is provided with valve rod, and described valve rod is arranged with spring, and described spring is in top cap and gives vent to anger between flap, described valve rod
Lower end is through giving vent to anger flap, and connection has screw rod, and described screw rod upper end is fixing with valve rod to be connected, and lower end passes through in housing
Air inlet flap, and carry out spacing cooperation by nut, described in flap lower end of giving vent to anger be provided with seal washer, described seal washer upper end
Fit with air outlet valve flap seal, lower end and housing and the laminating of intake valve flap seal, described in flap of giving vent to anger be provided with passage.
As the further optimization of this programme, described top cap vertical cross-section is trapezoidal.
As the further optimization of this programme, described in flap lower end of giving vent to anger be provided with groove, described seal washer is arranged on recessed
In groove.
As the further optimization of this programme, described vent shapes is fan-shaped.
This utility model beneficial effect:
This utility model structure is compact to design, and air inlet flap is together with flap design of giving vent to anger, non-interference, storage tank superpressure
Time system can open flap of giving vent to anger, and only can open air inlet flap during storage tank low pressure.This utility model uses simple, it is only necessary to be arranged on
The top of tank car, this valve need not user and goes open and close, is to automatically control flap according to the pressure size of gas in storage tank,
Pressure inside the tank is failure to actuate at span of control interior trim, flap, keeps the sealing of storage tank.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described in further detail:
Fig. 1 is this utility model sectional structure schematic diagram；
Fig. 2 is this utility model air outlet valve valve structure schematic diagram；
In figure, 1, housing, 2, top cap, 3, ventilation mouth, 4, flap of giving vent to anger, 5, valve rod, 6, spring, 7, screw rod, 8, intake valve

Detailed description of the invention
With embodiment, this utility model is described further below in conjunction with the accompanying drawings.
Embodiment:
As depicted in figs. 1 and 2, a kind of breather valve, including housing 1, described housing upper end is arranged with top cap 2, described top cap
Side, lower end is fastenedly connected by bolt with housing, is provided with ventilation mouth 3 between opposite side and housing, and described housing upper end sets
Give vent to anger flap 4, described in flap upper end of giving vent to anger be provided with valve rod 5, described valve rod is arranged with spring 6, described spring is positioned at top cap
And giving vent to anger between flap, described valve rod lower end is through giving vent to anger flap, and connection has screw rod 7, described screw rod upper end to fix with valve rod
Connecting, lower end passes through the air inlet flap 8 in housing, and carries out spacing cooperation by nut 9, described in flap lower end of giving vent to anger set
Seal washer 10, described seal washer upper end is had to fit with air outlet valve flap seal, lower end and housing and the laminating of intake valve flap seal,
Described flap of giving vent to anger is provided with passage 11.
As the further optimization of this programme, described top cap vertical cross-section is trapezoidal.
As the further optimization of this programme, described in flap lower end of giving vent to anger be provided with groove 12, described seal washer is arranged on
In groove.
As the further optimization of this programme, described vent shapes is fan-shaped.
Specific works principle:
As depicted in figs. 1 and 2, when storage tank oil-feed state, flap 4 of giving vent to anger is opened, and in oil storage tank, air discharges；Storage
When tank is fuel-displaced, air inlet flap 8 is opened, and outside air enters oil storage tank, keeps oil storage tank internal and external pressure balance；Oil storage tank stop into
When going out oil condition, air outlet valve and intake valve simultaneously close off, and are isolated from the outside by oil storage tank, prevent from running outside gaseous oil product.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any those of ordinary skill in the art, can be without creative labor in the technical scope disclosed by this utility model
The dynamic change expected or replacement, all should contain within protection domain of the present utility model.Therefore, protection model of the present utility model
Enclose and be as the criterion with the protection domain that claims are limited.
