DETAILED DESCRIPTION OF THE PRESENT INVENTION

Embodiment 1

(14) As shown in FIG. 1 and FIG. 2, the self-adjustable gas isolator of the embodiment 1 includes a floater 1, a pressure balancing device 2 and a liquid storage device 3; the floater 1 is provided with a groove 1a, and a pressure relief port 1b is arranged on the groove 1a; the pressure balancing device 2 comprises a first sealing element 2a; the liquid storage device 3 is provided with a liquid discharge opening 3a, and a liquid discharge hole 4a is arranged on the cover plate 4; the floater 1 is arranged in the liquid storage device 3, and the floater 1 floats in the liquid storage device 3; one end of the first sealing element 2a is arranged on the floater 1, and the other end of the first sealing element 2a is in sealing contact connection with the pressure relief port 1b.

(15) The working process of the self-adjustable gas isolator described by the embodiment 1 is as follows: assuming the liquid storage device 3 is in a liquid with no buoyancy or in the initial state after the liquid is discharged, the floater 1 is at the lowest position and seal the liquid outlet 3a for blocking the liquid outlet 3a and the gas channel of the liquid storage device 3.

(16) If the liquid flows into the liquid storage device 3 to continuously raise the liquid level, and when the liquid level rises to the buoyancy greater than the weight of the floater 1 and the pressure balancing device 2, the floater 1 rises accordingly, and then the floater 1 leaves the liquid outlet 3a and opens the liquid discharging channel to start discharging liquid. The height of the floater 1 is related to the liquid flow rate and the liquid discharge speed, if the inflow speed of the liquid is high, the liquid discharging speed is low, and the liquid level continues to rise, the distance between the floater 1 and the liquid outlet 3a is larger, and the liquid discharging speed is higher. When the balance is achieved, the liquid level keeps unchanged, and otherwise, the liquid level decreases to the balance position.

(17) After the liquid enters the closed discharging channel, the space in the channel becomes small to generate pressure, and the pressure is opposite to the flowing direction of the liquid, so the discharge liquid is under resistance, and the liquid discharging speed slows down. The liquid flowing into the liquid storage device is larger than the liquid discharged out of the liquid storage device, the liquid level rises. When the floater 1 rises to a certain height, the floater 1 inclines to release pressure. Without the pressure, the liquid discharge speed is accelerated, and the liquid level is reduced to reach balance accordingly.

(18) When the volume of liquid flowing into is changed or the liquid level is reduced, a negative pressure is generated by the liquid discharging channel, the suction force of the negative pressure enables the floater 1 to move downwards, and the liquid discharged by the floater 1 is increased, and the suction force on the pressure balancing device 2 is increased; when the suction force is larger than the opening force of the pressure balancing device 2, and one end of the first sealing element 2a which is in sealing contact connection with the pressure relief port 1b generates deformation or displacement, the pressure relief port 1b is opened to release the pressure. After the pressure is released, the pressure balancing device 2 is closed, the floater 1 cannot be sucked on the liquid outlet 3a due to negative pressure to block the liquid discharging channel, and the isolator continues to work normally. After the liquid discharge is completed, the floater 1 falls back to the lowest position of the initial state, and the gas channel of the liquid discharging port 3a is closed.

Embodiment 2

(19) As shown in FIG. 3, FIG. 4, FIG. 5 and FIG. 8 is the self-adjustable gas isolator of the embodiment 2, the basic structure of the present embodiment is the same as the embodiment 1, and the differences are as follows: the self-adjustable gas isolator further comprises a cover plate 4, the pressure balance device 2 comprises a fifth sealing element 2i, and the first sealing element 2a is omitted; a liquid discharging hole 4a is arranged on the cover plate 4, a convex block 4b is arranged on the cover plate 4 or the floater 1; one end of the fifth sealing element 2i is fixedly arranged on the floater 1, and the other end of the fifth sealing element 2i is in sealing contact connection with the pressure relief port 1b.

(20) Liquid flows into the liquid storage device 3 through the liquid discharge hole 4a to enable the floater 1 to rise to be balanced, and the pressure borne by the pressure balancing device 2 is equal to the weight of the floater 1 and is smaller than the opening force of the pressure balancing device 2. If the positive pressure is generated, the floater 1 continues to rise along with the liquid, when being in contact with the convex block 4b, the floater 1 stops rising (assuming that the convex block 4b is arranged on the floater 1, it should be the convex block 4b being in contact with the cover plate 4), the pressure borne by the pressure balancing device 2 is equal to the liquid weight of the liquid volume discharged by the floater 1, and is larger than the opening force of the fourth sealing element 2g, one end of the fourth sealing element 2g which is in sealing contact connection with the pressure relief port 1b generates deformation or displacement, and the other end of the sealing element is connected with the pressure relief opening 1b in a sealing mode, the pressure relief opening 1b is opened or deformed to release the pressure, and the pressure balancing device 2 is closed after release, the liquid discharge speed is accelerated, and the liquid level is reduced until reaching a balance state. The case of negative pressure is the same as in embodiment 1.

Embodiment 4

(21) As shown in FIG. 1, FIG. 3, FIG. 4, FIG. 5 and FIG. 6 is the self-adjustable gas isolator of the embodiment 4, the basic structure of the present embodiment is the same as that of the embodiment 1, the embodiment 2 and the embodiment 3, and the differences are as follows: the pressure balancing device 2 is changed into a spring type structure, comprising a second sealing element 2b, a spring 2c and an ejector rod 2f; two ends of the spring 2c are respectively arranged on the ejector rod 2f and the floater 1, the second sealing element is in sealing contact connection with the pressure relief port 1b.

(22) When the floater 1 generates a negative pressure which is larger than the elastic force of the spring 2c, and the suction force of the negative pressure enables the spring 2c to deform, the second sealing element 2b opens the pressure relief port 1b which is in sealing contact connection. When the positive pressure liquid level rises and the top rod 2f is lifted to the cover plate 4 along with the liquid level and the floater 1, the ejection rod 2f is under the action force of the buoyancy force and the cover plate 4, the spring 2c is compressed, and the second sealing element 2b opens the pressure relief port 1b to release pressure.

Embodiment 5

(23) As shown in FIG. 1, FIG. 3, FIG. 4, FIG. 5 and FIG. 7 is the self-adjustable gas isolator of the embodiment 5, the basic structure of the present embodiment is the same as the embodiment 1, the embodiment 1, the embodiment 2, the embodiment 3 and the embodiment 4, and the differences are as follows: the pressure balancing device 2 is changed into a magnetic structure, comprises a third sealing element 2d and a magnetic material 2e, an ejector rod 2f and a support 2h; the magnetic material 2e is made of a pair of attracted or repulsive materials, such as a magnet and an iron metal, or a pair of the magnet and matched materials, so that mutual attraction or repelling effects can be generated in a certain distance; the support 2h is arranged on the floater 1, and the ejector rod 2f is sleeved in the support 2h for axial movement; the magnetic material 2e are respectively arranged on the floater 1 and the third sealing element 2d, or arranged on the floater 1 and the ejector rod 2f.

(24) When the negative pressure generated on the floater 1 is larger than the interaction force of the magnetic material 2e, the suction force of the negative pressure overcomes the magnetic force to enable the third sealing element 2d to open the pressure relief port 1b to release the pressure. When the positive pressure is larger than the magnetic force, the ejector rod 2f pushes the third sealing element 2d to open the pressure relief port 1b to release the pressure.

(26) When the negative pressure generated on the floater 1 is larger than the elasticity of the elastic member 2j, and the suction force of the negative pressure enables the elastic member 2 to be deformed, the end of the first sealing element 2a in sealing contact connection with the pressure relief port 1b is displaced, and the pressure relief port 1b is opened to relieve pressure. the liquid level rises when positive pressure is generated, the protrusion 2k, the first sealing element 2a and the floater 1 all rise along with the liquid level, and when the protrusion 2k is contact with the cover plate 4, the elastic member 2j is deformed by the action force of the protrusion 2k under the buoyancy and the cover plate 4, the first sealing element 2a opens the pressure relief port 1b to release the pressure.

(27) Above disclosure are merely a part of typical examples of the self-adjustable gas isolator of the present invention, and the drawings are only a part of the schematic diagram. Regardless of the structure, shape and material of the pressure balancing device 2, any device including the floater 1, the pressure relief port 1b, the pressure balancing device 2 and the liquid storage device 3 falls within the protection scope of the present invention.
