Lid 11, be preset in the first connecting tube 12 that first bypass valve covers by the first pin shaft 13 pass through the through-hole realize with
The connection of the connecting column is equipped with the second bypass valve deck 14 in the upper end of the first bypass valve deck, is preset in described second
The second connecting tube 15 that bypass valve covers passes through the connection of sliding slot realization and the connecting column by the second pin shaft 16,
It is described first bypass valve deck and second bypass valve deck between be equipped with spring 17, the escape pipe sequentially pass through the first bypass valve deck,
First bypass valve deck is placed in the tank body, and the lower end of the vacuum pure air balancing device passes through first bypass
Valve deck is placed in the second bypass valve and covers end.
Preferably, the lower section for bypassing valve deck in the bleeder port and positioned at described first is equipped with and first bypass
The mutually matched baffle 18 of valve deck.
Preferably, the diameter of the first bypass valve deck is less than the diameter of the first bypass valve deck.
Preferably, the diameter of the first bypass valve deck is the 7/8 of the diameter of the first bypass valve deck.
Preferably, the spring is the spring that rises.
Preferably, the spring is contraction spring.
Preferably, the vacuum pure air balancing device includes air filter 19 and air inlet pipe 20, the air inlet
Pipe is placed in the second bypass valve across the first bypass valve deck and covers end.
Working method and principle:
As shown in Fig. 1, the first bypass valve deck and the second bypass valve deck are in inside bleeder port at this time, and real with tank body
It now seals, prevents the intracorporal gas discharge (as long as the end of escape pipe does not have valve opening) of tank.
Simultaneously (upper end of escape pipe is equipped with air pump or other getter devices to air-breathing, this does not belong to after the end valve opening of escape pipe
In protection scope of the present invention, the present invention lays special stress on protecting two layers of valve), the intracorporal air pressure of tank is negative pressure, thus the second bypass valve
The air pressure for covering end is far longer than the air pressure of the first bypass valve deck lower end, and the first bypass valve is caused to cover tightly tight cover in bleeder port
On, to realize sealing function.
When needing make-up gas in tank body, start cylinder, cylinder pulls up valve member, in this way, because the first bypass
Valve deck than second bypass valve deck diameter it is small, slightly by first bypass valve deck pull up after, be located at first bypass valve deck and second by
Air inlet pipe between the valve deck of road will be automatically by (being negative pressure in tank body) in clean gas suction tank body, in this way, realizing in tank body
The ventilation work of interior gas.
It is well known that pervious flap is all that surrounding is enclosed with sealing ring, the pulling back and forth of sealing ring is easy damage
It is bad, lose sealing effect, the present invention realizes the change to sealing effect matter using the double-deck bypass valve deck, realizes the by air pressure
One bypass valve deck covering on bleeder port tightly, realizes sealing effect, it is most important that, the diameter of the first bypass valve deck is less than
Second bypass valve deck, slightly lift the first bypass valve deck, can be achieved with pouring into for gas, in this way, being avoided that cylinder by the
One bypass valve deck lifts realization air inlet completely.
As another aspect of the present invention, equipped with spring, (this is very between the first bypass valve deck and the second bypass valve deck
The important point), as shown in Fig. 2, overhauls and finish after cylinder extracts valve member completely, be inserted by valve member
In bleeder port, it is easy to cause blocking for the second valve member and bleeder port wall portion, causes the second valve member to lose sealing and makees
With after using spring, the second valve member capable of being promoted to be restored to normal position to greatest extent, this is that the present invention is maximum
Where innovative point, it is necessary to sliding slot is set, allows the second valve member that there can be the position of self-regulation, it, can with the effect of spring
The second valve member is promoted slowly to be restored to normal position, to realize permanent sealing effect.
It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, without necessarily requiring or implying between these entities or operation
There are any actual relationship or orders.Moreover, the terms "include", "comprise" or its any other variant are intended to
