Technology can more reliably ensure being isolated for insulating oil and air, and have the work longevity while realizing insulating oil volume compensation
Life is long, without aging, resisting breakage and it is non-maintaining the features such as, be completely suitable for all kinds of oil-immersed transformers, reactor and capacitor etc.
Power equipment.Outer oil type bellow oil conservator is widely used to the power equipments such as all kinds of oil-immersed transformers, capacitor at present, though
Have many advantages, such as good airproof performance, easy for installation, but the ripple core of its inner flexible stainless steel belongs to thin-walled vulnerable part, one
Denier is impaired to be safeguarded, can only be to oil conservater integral replacing.
Invention content
In view of the deficienciess of the prior art, it is an object of the present invention to provide a kind of outer oil type bellow oil conservator pressure balances
Valve, to solve the problems mentioned in the above background technology.
To achieve the goals above, the present invention is to realize by the following technical solutions：A kind of outer oil type ripple oil storage
Cabinet equilibrated valve, including upper valve body, the lower valve body with upper valve body lid conjunction；After the upper valve body is closed with the lower valve body lid
It is formed in the interior thereof cavity, the upper valve body in cavity is equipped with downwardly convex step groove, and is equipped in cavity and is stuck in platform
The other end of resetting spring on rank slot, the resetting spring is connected with flap, and the flap is arranged to arc-shaped, described
Flap is closed with the through-hole lid that the lower valve body is equipped with, and the lower valve body is equipped with auxiliary mounting hole, and in addition the upper valve body passes through
Balanced valve is formed after being tightly connected equipped with fastening bolt and the lower valve body.
As the preferred technical solution of the present invention：The oil conservater is internally provided with sealing plate, and is filled in the left side of sealing plate
Connecting hole is offered equipped with ripple core, and in the middle of sealing plate, the balanced valve is installed on connecting hole.
Using above-mentioned technical proposal, the beneficial effects of the invention are as follows：It is provided with connection on the sealing plate of oil conserver ripple core end
The balanced valve is assembled in hole；When vacuum degree reaches balanced valve setting value, the flap of balanced valve is opened when transformer vacuumizes, and makes wave
Line core medial and lateral unicom realizes pressure balance to play the effect of protection ripple core；When in oil conserver ripple core,
Balanced valve will carry out closing motion when outside pressure tends to balance, and oil conserver ripple core medial and lateral is made to be fully disconnected；Balanced valve
It plays a protective role when only in transformer vacuum state, corrugated core body medial and lateral pressure difference changes greatly, oil storage when not influencing to put into operation
The normal respiratory movement of cabinet ripple core.
