Liquid flows into liquid storage device liquid level and raises, and when liquid level is elevated to the weight being greater than float and pressure equaliser, float rises thereupon, and float leaves liquid port and opens apocenosis passage and start discharge opeing.The height of float is relevant with the speed of fluid flow and discharge opeing, if the speed that liquid flows into is fast, the speed of discharge opeing is slow, and liquid level just continues to raise, and the distance of float and liquid port is also larger, and the speed of discharge opeing is also faster, and when equilibrium is reached, liquid level remains unchanged.Otherwise liquid level drops to equilibrium position.
Liquid enters closed apocenosis passage, and make the space of gas in passage diminish and produce pressure, discharge opeing will be subject to resistance, and the speed of discharge opeing will be slack-off, and float and liquid level increase.
When float rises to a certain height, float run-off the straight is by earth pressure release, and without pressure, drain age velocity is accelerated, and liquid level drops to and reaches balance.
When lifting rate changes or terminate discharge opeing, the change of liquid level makes apocenosis passage produce negative pressure, the suction of negative pressure makes float move down, the volume that liquid floods float increases, the negative pressure that pressure equaliser is subject to increases, when this negative pressure is greater than pressure equaliser opening force, Sealing one and pressure relief opening seal and contact the one end connected and produce deformation or displacement, open pressure relief opening release negative pressure, after pressure release, pressure equaliser is closed, state of equilibrium got back to by float, and float can not be inhaled because of negative pressure and block apocenosis passage on liquid port.
A kind of preferred version as self-regulated of the present invention floating type hermetic seal device: this preferred version basic structure is with technological scheme above, and difference is: described pressure equaliser also comprises Sealing two, spring, push rod, cover plate, outage; Described push rod is arranged on Sealing two, and outage is arranged on the cover board; Described pressure equaliser is fixedly mounted on float, and spring housing is contained on push rod, and one end of spring is arranged on push rod, and the other end is arranged on float, and Sealing two and pressure relief opening seal to contact and connect.The elastic force of spring makes to form a pressure release passage between float and cover plate, and cover plate is arranged on liquid storage device.
Its working procedure is: when producing malleation, float rises with liquid level, and after push rod is also increased to cover plate with float, when the pressure of buoyancy and cover plate that push rod is subject to float is greater than spring force, push rod makes spring-compressed, and Sealing two leaves pressure relief opening release pressure.When generation negative pressure, negative-pressure sucking acts on Sealing two, and when suction is greater than spring force, Sealing two opens pressure relief opening release negative pressure.
As the second preferred version of the present invention: the same a kind of preferred version of this preferred version basic structure, difference is: described pressure equaliser magnetic-type instead of spring, comprises Sealing three, magnetic material, push rod, support.
