Abstract
The present invention relates to a kind of vacuum tank valve type mouth-sealing method, comprise the following steps：1) bellmouth is gone out on container bottom shell, is then combined the inner casing and shell of whole container integral；2) steel ball by container bottom upward, is placed in bellmouth；3) air exhaust nozzle is connected at the top of bellmouth to be vacuumized, stop pumping after vacuum reaches setting value；4) air exhaust nozzle for vacuumizing rear container is withdrawn, because there is certain vacuum degree in container, so steel ball is pressed tightly against inside bellmouth, realize the automatic closing of check valve, because pull of vacuum is more than the deadweight of steel ball, so container is placed in any state, steel ball will not loosen or come off.Vacuum tank valve type mouth-sealing method processing step of the invention is simple, cost is extremely low, device simple；The check valve being made up of steel ball and bellmouth has self-sealing advantage, easy to operate, and production efficiency is high.
Description
Technical field
The present invention relates to a kind of vacuum tank valve type mouth-sealing method.
Background technology
At present, there are two kinds of sealing process in the manufacture field of vacuum tank, one is traditional gas nozzle skewer welding method, and two are
The overall vacuum method of forming.All have the shortcomings that high energy consumption, complex process, efficiency is low, equipment investment is big.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of vacuum tank valve type mouth-sealing method.
The vacuum tank valve type mouth-sealing method of the present invention, comprises the following steps：
1) bellmouth is gone out on container bottom shell, is then combined the inner casing and shell of whole container integral；
2) steel ball by container bottom upward, is placed in bellmouth；
3) air exhaust nozzle is connected at the top of bellmouth to be vacuumized, stop pumping after vacuum reaches setting value, now,
Vacuum inside container is consistent with whole extract system, and pressure reaches balance, and steel ball falls in bellmouth under gravity
Bottom；
4) air exhaust nozzle for vacuumizing rear container is withdrawn, because there is certain vacuum degree in container, so steel ball is pressed tightly against
Inside bellmouth, the automatic closing of check valve is realized, because pull of vacuum is more than the deadweight of steel ball, so container is in any shape
State is placed, and steel ball will not loosen or come off.
The vacuum tank valve type mouth-sealing method of the present invention, in step 4) in：In order to ensure the durability and stability of container,
In the outside of bellmouth and steel ball, protection glue is coated, makes the sealing and reliability of air valve higher；Glue now is only served
Protective action, so the requirement to glue is extremely low to sealed function influence less.
Beneficial effects of the present invention are compared with prior art：The vacuum tank valve type mouth-sealing method processing step of the present invention
Simply, cost is extremely low, device simple；The check valve being made up of steel ball and bellmouth has self-sealing advantage, easy to operate,
Production efficiency is high.
Brief description of the drawings
Fig. 1 is the structural representation of the container in a kind of vacuum tank valve type mouth-sealing method described in the embodiment of the present invention.
Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
As shown in figure 1, a kind of vacuum tank valve type mouth-sealing method, comprises the following steps：
1) bellmouth 3 is gone out in the bottom enclosure 2 of container 1, be then combined into the inner casing 4 and shell 2 of whole container 1 whole
Body；
2) it is container 1 is bottom-up, a steel ball 5 is placed in bellmouth 3；
3) connect air exhaust nozzle 6 at the top of bellmouth 3 to be vacuumized, stop pumping after vacuum reaches setting value, this
When, the vacuum inside container 1 is consistent with whole extract system, and pressure reaches balance, and steel ball 5 falls in cone under gravity
The bottom of shape hole 3；
4) air exhaust nozzle 6 for vacuumizing rear container 1 is withdrawn, because having certain vacuum degree in container 1, so steel ball 5 is closely
It is pressed in inside bellmouth 3, realizes the automatic closing of check valve, because pull of vacuum is more than the deadweight of steel ball 5, so container 1
Placed in any state, steel ball 5 will not loosen or come off.
The vacuum tank valve type mouth-sealing method of the present invention, in step 4) in：In order to ensure the durability and stably of container 1
Property, in the outside of bellmouth 3 and steel ball 5, protection glue is coated, makes the sealing and reliability of air valve higher；Glue now
Protective action is only served, so the requirement to glue is extremely low to sealed function influence less.
Vacuum tank valve type mouth-sealing method processing step of the invention is simple, cost is extremely low, device simple；By steel ball and cone
The check valve that shape hole is constituted has self-sealing advantage, easy to operate, and production efficiency is high.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and modification can also be made, these improvement and modification
Also it should be regarded as protection scope of the present invention.
Claims (2)
1. a kind of vacuum tank valve type mouth-sealing method, it is characterised in that comprise the following steps：
1) bellmouth is gone out on container bottom shell, is then combined the inner casing and shell of whole container integral；
2) steel ball by container bottom upward, is placed in bellmouth；
3) air exhaust nozzle is connected at the top of bellmouth to be vacuumized, stop pumping, now, container after vacuum reaches setting value
Internal vacuum is consistent with whole extract system, and pressure reaches balance, and steel ball falls in bellmouth bottom under gravity；
4) air exhaust nozzle for vacuumizing rear container is withdrawn, because there is certain vacuum degree in container, so steel ball is pressed tightly against taper
Inside hole, the automatic closing of check valve is realized, because pull of vacuum is more than the deadweight of steel ball, so container is put in any state
Put, steel ball will not loosen or come off.
2. vacuum tank valve type mouth-sealing method according to claim 1, it is characterised in that in step 4) in：In order to ensure
The durability and stability of container, in the outside of bellmouth and steel ball, coat protection glue, make the sealing and reliability of air valve
