The pressure regulating means 30 includes a fixed plate 32 spaced above the disk 31 and a plurality of circularly arranged disks 31 and a fixed plate 32 A first tension member 34 provided on the outer circumferential surface of the fixing shaft 33 and a second tension member 35 provided on the outer circumferential surface of the lower portion of the fixing shaft 33; And an adjusting member 36 provided between each tension member and an engaging hole 37 for fixing each tension member located at the upper and lower portions of the fixing shaft 33, A moving member 36b provided on the outer peripheral surface of the fixed shaft 33 and rods 36a and 36a 'provided on both ends of the moving member 36b.

The components and operation of the emergency pressure discharge device 100 of the present invention constructed as described above will be described in detail as follows.

As shown in Figs. 1 to 4,

The present invention consists largely of a combination body 10, a hermetic packing 20, and a pressure regulating means 30.

The coupling body 10 is coupled to the upper end of the opening of the storage tank 1 and has a circular outlet 12 at the center and has a coupling hole 11 formed on the upper surface thereof, And a circular groove is formed on the side of the coupling hole 11, and a ring-shaped sealing packing 20 is inserted.

The hermetic packing 20 is inserted into a circular groove formed in the upper part of the coupling body 10 and performs a sealing function by preventing leakage of gases, liquids, and the like.

The pressure regulating means 30 discharges air according to an internal pressure and a vacuum state of the storage tank 1 to perform a function of regulating a pressure state in the storage tank 1, To prevent safety accidents in advance.

The pressure regulating means 30 mainly includes a disk 31, a fixing plate 32, a fixing shaft 33, a first tension member 34, a second tension member 35, a regulating member 36, (37)

The disc 31 is formed in a disc shape and has a coupling hole 31a formed at a position corresponding to the coupling hole 11 having a plurality of circular arrays arranged on the upper surface of the coupling body 10, 20 to be in close contact with or released from the upper surface of the assembly 10 to control the pressure state inside the storage tank 1 and the flow of air.

The fixing plate 32 is spaced a predetermined distance from the top of the disc 31 and has a coupling hole 32a formed at a position corresponding to the coupling hole 31a formed in the disc 31 to be circularly arranged, And are fixedly coupled to each other by a shaft 33 and a coupling member 51.

The fixing shaft 33 is formed with threaded portions 33a at both ends and passes through the coupling holes 11, 31a and 32a formed in the coupling body 10, the disk 31 and the fixing plate 32, And functions to slide and guide the disc 31 upward or downward in accordance with the function of coupling and fixing the respective components to the coupling member 51 and the pressure inside the storage tank 1. [

The first tension member 34 and the second tension member 35 discharge or seal the inner air in accordance with the pressure inside the storage tank 1 by using a spring which resists the force to be compressed, The first tension member 34 is formed with a larger force to resist the compression force than the second tension member 35. [

The reason why the first tension member 34 and the second tension member 35 are set differently in terms of the force that resists the compression force is that the disc 31 is moved up and down according to the inner pressure of the storage tank 1 In order to control the flow of air more precisely in sliding and moving and discharging and sealing the inside air.

The adjustment member 36 is positioned between the first tension member 34 and the second tension member 35 to impart mutually corresponding forces to the resistance forces of the respective tension members 34 and 35, And performs a function of more precisely controlling the movement of the disc 31 in accordance with the internal pressure of the tank 1.

The adjusting member 36 includes a moving member 36b having a fixing jaw 36b-1 formed on an inner surface thereof and having a threaded portion formed on each of upper and lower portions with respect to the fixing jaw 36b-1, And rods 36a and 36a 'which are threadedly engaged and formed with threaded portions 36a-1 and 36a-1' in correspondence with the threaded portions of the threaded portions 36a and 36b.

The coupling member 37 is provided on the outer circumferential surface at both ends of the fixed shaft 33 and is positioned in the coupling holes 32a and 31a of the fixed plate 32 and the disk 31 to support the respective tension members 34 and 35 And has a tight contact portion 37a which is in close contact with the bottom face of the fixing plate 32 and the upper face of the disk 31 and a tension member 34 which is connected by the close contact portion 37a, And a fixing portion 37b to which an end portion of the fixing portion 35 is fixed.

Hereinafter, the operation of the present invention will be described.

As shown in Figs. 5 to 6,

When the oil vapor pressure is formed within the set range in the storage tank 1,

The second tension member 35 is compressed and the compressive force of the second tension member 35 is applied to the adjusting member 35 by the oil vapor pressure so that the disc 31 is vertically upwardly moved along the outer peripheral surface of the fixed shaft 33 by a predetermined distance, 36 and the first tension member 34 is compressed by the transmitted pressure so that the vapor of the storage tank 1 is discharged through the discharge port so that the vapor pressure of the oil in the storage tank 1 It falls below the setting range.

After the above operation, when the vapor pressure is sufficiently exhausted and the oil vapor pressure of the storage tank 1 is lowered, the respective compressed tension members 34 and 35 are restored, The seal packing 20 installed vertically downward along the outer circumferential surface of the fixed shaft 33 is pressed against the upper surface of the coupling body 10 so that the oil vapor pressure inside the storage tank 1 is set within a predetermined range .

On the other hand, when the oil vapor pressure is rapidly formed within the preset range in the storage tank 1,

The disk 31 is vertically upwardly raised by a certain distance along the outer peripheral surface of the fixed shaft 33 by the oil vapor pressure and the second tension member 35 and the first tension member 34 are compressed, Since the member 34 has a large force for resisting the compressive force of the second tension member 35, the member 34 interacts with the force generated from the first tension member 34, The vapor pressure of the oil in the storage tank 1 can be quickly and safely lowered to the set range or less by discharging the vapor through the discharge port uniformly in correspondence with the formed oil vapor pressure.

When the oil vapor pressure of the storage tank 1 is lowered after the above-mentioned operation, the compressed tension members 34 and 35 are restored, The sealing packing 20 provided on the upper surface of the coupling body 10 is pressed against the upper surface of the coupling body 10 so that the oil vapor pressure in the storage tank 1 can be maintained within the set range.

On the other hand, as shown in Fig. 7,

In the operation of the regulating member 36,

The load 36a and 36a 'coupled to the upper and lower portions of the regulating member 36 are rotated to change the magnitude of the pressing force of the tension members 34 and 35, It is possible to more precisely and effectively maintain a constant pressure in the storage tank 1 by controlling the upward and downward movement of the disk 31 acting in accordance with the vapor pressure, and at the same time, by controlling the flow of air, It is a great advantage to prevent safety accidents such as fire.

It is to be understood that the present invention is not limited to the above-described embodiment, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims. It will be understood by those skilled in the art that the technical spirit of the present invention is to the extent that various modifications can be made.
