Description

{OVER PRESSURIZATION VENT OF CHECK VALVE TYPE}

The present invention relates to a check valve type overpressure outlet, and more particularly, to a check valve type open / close plate operation when an overpressure occurs due to fire evolution caused by a fire extinguishing gas inside a protection area, so that internal pressure is lowered to prevent problems caused by overpressure Pressure check valve type overpressure outlet.

Generally, when a fire occurs, the fire is extinguished by spraying fire extinguishing agent such as water or foam.

However, there are places where electrical facilities such as electrical, substation, power generation, and storage rooms can not be used, such as water, foam, etc., and paper storage rooms, libraries, computer rooms, communication facilities, Museums that store or display fire extinguishing gas, fire extinguishing gas is used instead of fire extinguishing agents such as water or foam in places where flammable liquids or dangerous materials are stored.

These extinguishing gases use carbon dioxide, talon, nitrogen, and argon as inert gases.

In such a fire protection zone using fire extinguishing gas, overpressure is caused by the expansion of fire extinguishing gas when fire is extinguished by fire extinguishing gas, and there is a problem of damaging expensive equipments and facilities in the fire fighting area. Therefore, Of the total.

As shown in FIG. 1, the overpressure outlet is provided with a plurality of rotary plates 6 in the body 5 coupled to the installation hole 3 of the wall 2, such as a fan, The rotary plate 6 is opened and opened to lower the internal pressure, thereby preventing a problem caused by overpressure.

However, the above-mentioned overpressure outlet does not smoothly rotate the rotary plate 6, and in particular, since the inner pressure does not act uniformly on the rotary plates, the rotary plates do not constantly open and close, , The rotary plate 6 is not completely hermetically sealed at all times, causing gas leakage.

2, an opening / closing plate 7 is provided on the front surface of the body 5 coupled to the installation hole 3 of the wall body 2, and protruded to a plurality of positions behind the opening / closing plate 7 The load 7a is elastically supported by the elastic spring 9 in a state where the rod 7a is inserted into the guide hole 8 of the inner side wall of the body so that when the overpressure is generated due to fire extinguishing by the extinguishing gas, ) Is compressed and opened so that the internal pressure is reduced to prevent problems caused by overpressure.

However, since the overpressure outlet has a plurality of guide structures in which a plurality of rods 7a provided at the rear of the opening / closing plate 7 are inserted into the guide holes 8 of the inner side wall of the body, The rod 7a of the opening / closing plate can not be smoothly guided to the guide hole 8 due to the inability to function uniformly. As a result, the opening / closing operation of the opening / closing plate 7 is not constant, (6) is not completely airtight and there is a problem of gas leakage.

In addition, the conventional over-pressure outlet as shown in FIGS. 1 and 2 has a drawback in that the length of the body 5 must be made different depending on the thickness of the wall, and the inside of the body is damaged due to breakage of the rotating plate or the open / There is a problem that it is easy to penetrate inside because it has a structure which is completely opened.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The check valve type overpressure outlet of the present invention lowers the internal pressure by opening and closing operation of the opening and closing plate by the check valve system when overpressure occurs due to fire evolution by the fire extinguishing gas inside the protection area.

3 to 9, the present invention includes a body 10 to be embedded in and fixed to an installation hole 3 of a wall body 2, a piston insertion hole 16 integrally formed in the body, A piston 25 protruding from the center of the opening and closing plate and inserted into the piston insertion hole 16 of the fixed frame, A spring 26 inserted and coupled to the rear of the piston and a spring 26 screwed to the rear of the piston to adjust the tension of the spring 26 by adjusting the tension of the spring 26 And a pressure adjusting nut (27) for discharging the internal overpressure.

At this time, the opening / closing plate 20 is configured to be hermetically attached to the front surface of the body 10 by engaging with the rubber packing 21 for sealing.

A fixing bolt 30 into which the fixing member 35 is inserted is screwed to the rear edge of the body 10 so as to adjust the screw according to the thickness t of the wall body 2, And is pressurized and fixed at both sides of the wall body 2 by the body 10 and the support tabs 10a and 35a of the fixture 35. [

Preferably, the body 10 is formed in a rectangular shape, and the fixing bolts 30 are formed at four corner positions on the rear edge of the body 10.

In addition, the fixed frame 15 integrally installed in the body 10 is formed radially into the inside of the body so as to form a piston insertion hole 16 at the center thereof and to prevent the intrusion through the inside of the body .

The opening / closing plate 20 may be formed in a circular shape as shown in FIG. 4, or may be formed in a rectangular shape as shown in FIG.

Reference numerals 10a and 10b denote threaded holes and threaded portions on the rear side of the rod, respectively.

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

The present invention is mounted so as to be embedded in an installation hole (3) formed in a wall (2) of a protection zone.

That is, the body 10 is inserted in front of the installation hole 3 of the wall, and a support protrusion 10a protruding from the front edge of the body is inserted into the installation hole so as to be hooked in front of the installation hole, The fixing bolts 30 screwed to the back of each corner of the body 10 are tightened.

The fixture 35 inserted in the fixing bolt 30 is fixedly installed by pressing the rear of the mounting hole 3 with the supporting step 35a.

9, the fixture 35 can be moved back and forth along the fixing bolt 30, so that the fixture 35 can be moved back and forth in accordance with the thickness t, t + a of the wall body 2, The body 10 can be fixedly installed regardless of the thickness of the body 10.

After installing the fire extinguisher in the installation space 3 formed in the wall 2 of the protection zone as described above, the fire pipe 20 is attached to the spring 26 So as to be brought into close contact with the front of the body 10 by the tension force of the body 10.

Particularly, since the sealing rubber packing 21 is wrapped around the rim of the opening / closing plate 20, the rubber packing 21 is hermetically attached to the front surface of the body 10 to prevent gas leakage .

The spring 26 inserted in the rear of the piston 25 adjusts the tension force by adjusting the degree of screwing of the pressure adjusting nut 27 screwed to the rear of the piston so that the rubber of the opening / The degree of tightness of the packing 21 against the front surface of the body 10 is adjusted to effectively control airtightness and to control the opening and closing reaction of the opening and closing plate 20.

When the overpressure is generated in the protection zone when the fire is extinguished by fire of the fire in the protection zone in such a state, the open / close plate 20 (20) which is in close contact with the front of the body 10 by the tension force of the spring 26 Is opened while being moved forward to discharge the internal gas to the outside, thereby preventing a problem caused by the overpressure of the protection zone.

At this time, since the single piston 26 protruding from the rear center of the opening / closing plate 20 is inserted and guided into the piston insertion hole 16 at the center of the fixed frame inside the body, 20, the opening / closing plate 20 moves forward while maintaining the horizontal position, so that the open / close operation of the opening / closing plate 20 is smooth and the operability is excellent.

In addition, according to the present invention, the simple structure in which the single piston (26) of the opening and closing plate (20) is guided can simplify the assembly and installation and reduce the manufacturing cost. The structure in which the stationary frame 15 is integrally formed inside the body 10 effectively prevents the problem of intrusion from the outside through the inside of the body 10 even if the open / close board 20 is broken from the outside .
