Background technique
Certain gas would generally be generated when liquid transporting, gas, which is accumulated in liquid bag or transfer cask, can generate biggish pressure
Power causes quick-fried bag or other security risks.Exhaust valve exhaust can be used under normal conditions, in case pressure is excessive.But it is existing
The volume that exhaust valve has is excessive, is not suitable for small transport device or liquid bag uses, easily cause liquid bag damaged, generate leakage.Have
Exhaust effect is poor, and the pressure for needing to reach certain could be vented, and makes have certain pressure in transport device, there are biggish peaces
Full hidden danger.
Utility model content
The purpose of this utility model is to provide for a kind of floating-type automatic exhaust steam valve can when there is gas generation in device
Gas to be discharged in time, good exhaust effect, easy to leak, not small in size, easy to use.
To solve the above problems, the utility model provides a kind of floating-type automatic exhaust steam valve, including shell, upper cover, reflux
Chamber body, chassis and float body, the shell upper end are equipped with reflux chamber body, are equipped with upper cover in the reflux chamber body, it is described on
Protrusion is equipped among lid lower end, raised centre is hollow structure, multiple gas vents are additionally provided on the upper lid, the shell
Upper end is also equipped with top cap, float body is also equipped in the shell, the float body is mounted on the lower section of reflux chamber body, described
The upper end opening for the chamber body that flows back is big, and lower ending opening is small, and the lower end for the chamber body that flows back is equipped with sealing ring, and the upper end of the float body is circle
Taper, case inside are equipped with multiple perpendicular ribs, and housing bottom two sides are respectively equipped with an air inlet, and the shell lower end is also equipped with
Chassis is equipped with gland on chassis.
Further, the shell lower end outside is equipped with screw thread, is connected through a screw thread between the chassis and the shell.
Further, it is connected between the chassis and the gland by screw bolt and nut.
Further, gasket is equipped between the gland and bolt.
Further, sealing ring is equipped between the upper cover and the shell.
Further, sealing ring is equipped between the chassis and the shell.
By adopting such a design, the utility model at least has the following advantages:
The automatic exhaust steam valve of the utility model there are when a small amount of gas, that is, openable valve, gas is discharged, is not necessarily to gas
Reach biggish pressure, the float body seal process open and close of the product are flexible, and intelligence is reliable, can achieve zero air pressure exhaust, thorough
Bottom solves the problems, such as that liquid container bag generates gas pressure limiting exhaust.
Upper cover uses anti-overflow design, prevents liquid from splashing out, the liquid of spilling can flow back into valve body in time, will not splash
Outside valve body, securely and reliably.
Detailed description of the invention
Above-mentioned is only the general introduction of technical solutions of the utility model, in order to better understand the technology hand of the utility model
Section, below in conjunction with attached drawing, the utility model is described in further detail with specific embodiment.
Fig. 1 is the structural schematic diagram of the floating-type automatic exhaust steam valve of the utility model.
Wherein, 1 is top cap, and 2 be upper cover, and 3 be reflux chamber body, and 4 be bolt, and 5 be gasket, and 6 be chassis, and 7 be float body, 8
It is gland for nut, 9,10 be sealing ring, and 11 be shell, and 12 be gas vent, and 13 be protrusion.
Specific embodiment
Shown in referring to Fig.1, the utility model provides a kind of floating-type automatic exhaust steam valve, including shell 11, upper cover 2, reflux
Chamber body 3, chassis 6 and float body 7,11 upper end of shell are equipped with reflux chamber body 3, are equipped with upper cover in the reflux chamber body 3
2, the centre of 2 lower end of upper cover is equipped with protrusion 13, and the centre of protrusion 13 is hollow structure, is additionally provided in the upper cover 2 multiple
Gas vent 12, the upper end of the shell 11 are also equipped with top cap 1, float body 7, the float body are also equipped in the shell 11
7 are mounted on the lower section of reflux chamber body 3, and the upper end opening of the reflux chamber body 3 is big, and lower ending opening is small, and the lower end of reflux chamber body 3 is set
There is sealing ring, the upper end of the float body 7 is cone, and multiple perpendicular ribs 14,11 two sides of the bottom of shell point are equipped on the inside of shell 11
Not She You an air inlet 15, the shell lower end is also equipped with chassis 6, gland 9 is equipped on chassis 6.
11 lower end outside of shell is equipped with screw thread, is connected through a screw thread between the chassis 6 and the shell 11.
It is connected between the chassis 6 and the gland 9 by bolt 4 and nut 8.
Gasket is equipped between the gland 9 and bolt 4.
Sealing ring 10 is equipped between the upper cover 2 and the shell 11.
Sealing ring 10 is equipped between the chassis 6 and shell 11.
When not having gas, liquid level rises, and float body is surrounded, and float body is floated by buoyancy, float body
Upper end is contacted with the sealing ring of reflux chamber body lower end, makes float body top closure, to close valve.
When generating gas in liquid, gas rising is centered around around float body, and float body is reduced by the buoyancy of liquid
Or not by liquid buoyancy, float body declines under the effect of gravity, and float body is not contacted with the sealing ring of reflux chamber body lower end, valve
Door is opened, and gas is automatically drained out.
When liquid, which is sprung up, causes exhaust valve dipping and heaving, float body by upward resultant force also can dipping and heaving variation,
Sealing will appear loose or tight phenomenon, at this point, when thering is a small amount of liquid to spill into the return passage body on top in time, in upper cover
Between protrusion hollow structure liquid splash can be effectively prevented.The gas vent of upper cover uses inverted plug type structure, further prevents
Liquid is overflowed from the gas vent of upper cover, and during springing up, the liquid of return passage from float body and returns under self gravitation effect
In the clearance backflow to shell of the sealing ring of flow chamber body lower end.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, those skilled in the art make a little simple modification, equivalent variations or modification using the technology contents of the disclosure above,
It falls within the protection scope of the present utility model.
