Abstract

The utility model discloses an energy-saving pressure release window special for a line control type communication computer room, which comprises a window frame and a window sash, wherein the bottom side of the window sash is articulated on the window frame, and the upper side of the window sash is connected with a fixing part on the window frame through a pressure control line; and the fixed part is positioned on one side of the window frame adjacent to indoor. The control intensity F (K) of a breaking point of the pressure control line is equal to environmental pressure P in a fire zone*window sash area S/2. The release pressure of the pressure release window is quantitatively controlled by adopting the structure of the control line; and the fire control, the energy saving and other code requirements are satisfied by applying cesium-kalium hollow glass, fire hinges and other materials as well as structural measures. Meanwhile, the utility model has the advantages of simplicity, practical use and reuse and larger popularization and application values.

Description

Wire controlled communications equipment room energy-saving pressure release window

Technical field:

The utility model relates to a kind of wire controlled communications equipment room energy-saving pressure release window.

Background technology:

Existing gas extinguishing system, be that extinguishing chemical is released when breaking out of fire, play the effect of fire extinguishing when reaching finite concentration, yet, if the too high meeting of agent concentration that discharges produces superpressure in fire district, cause building or ancillary facility in the fire district to be damaged, this has the function of pressure release with regard to requiring the construction wall in the fire district, when producing superpressure, extinguishing chemical is released out, reach the purpose that to put out a fire and not damage facility in the fire district, by the investigation of practice, we find that all there is certain defective in existing various forms of pressure release windows in the communications equipment room, gather as follows:

1, pressure release equipment such as relief valve mainly is the technical requirements of satisfying safety precaution under extra-high tension unit and the environment, is not suitable for the balanced environment requirement of the needed low-pressure of gas extinguishing system in the communications equipment room, can not play self-relieving effect;

2, self hang down type metal pressure release window can satisfy the balanced environment requirement of the needed low-pressure of gas extinguishing system in the communications equipment room, but it exists the fire-resistant time limit weak point of metal lappet not meet the demands; The metal lappet forms the drawback that heat bridge can not satisfy the energy conservation criteria requirement simultaneously;

3, common disconnected hot aluminium medi-empty glass window exists pressure release pressure uncontrollable, and there is unsafe hidden danger in the glass fragment that forms after the explosion.

Therefore, though the requirement that pressure release technology such as existing pressure release window can satisfy standard substantially and use, but still have different technological deficiencies, mainly be the following aspects:

1) pressure is uncontrollable, and in use all there is the defective of the pressure that can not quantitatively control environment in existing all kinds of pressure release windows; 2) can not satisfy fire-fighting and many-sided code requirement such as energy-conservation simultaneously; 3) there is certain potential safety hazard.

Summary of the invention:

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of pressure release window, can satisfy normal airtight demand in the fire district, also have and do not produce heat bridge effect, effect of saving energy, pressure can quantitatively control environment simultaneously, play the pressure release effect when needed, and do not have potential safety hazard.

The utility model technical solution problem adopts following technical scheme:

Wire controlled communications equipment room energy-saving pressure release window comprises window frame and sash, and the base of sash is articulated on the window frame, and the top of described sash is connected with fixture on the window frame by pressure control line, and described fixture is in window frame near an indoor side.

Described sash is made of the caesium potash glass of bilayer and the shape that is fixedly arranged on around the double-deck caesium potash glass, forms vacuum between the two-layer caesium potash glass or does not form vacuum.

Described pressure control line can rupture when sash is subjected to certain pressure, and its design formulas is as follows: environment stress P * sash area S/2 in pressure control line breakaway poing control intensity F (K)=fire district.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

Be connected with the fire prevention hinge between one side of the utility model sash and the window frame, the another side of sash is connected with fixture on the window frame by pressure control line, because the control intensity of control line breakaway poing can be according to the code requirement designing and calculating, control method is simple, only utilize the mechanical characteristic of material itself can satisfy necessary requirement, when reaching designing requirement, room pressure ruptures voluntarily, form smooth open type pressure relief opening fast, satisfy the requirement of extinction using gas fire fighting system, and sash is drawn by hinge, can not break away from window frame, can be not impaired yet, can reuse.

The limit of the utility model sash is made by disconnected thermometal section bar, be double-deck caesium potash glass in the middle of the sash, have the function of heat-insulating and energy-saving, sealing and dustproof, have a higher requirement to heat insulation as if indoor, can will vacuumize between the double-layer glass, to improve the heat-insulating and energy-saving effect; Caesium potash glass of the present utility model also has explosion-proof advantage.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 A is the A-A sectional view of Fig. 1.

Structural representation when Fig. 2 B opens for the sash shown in Fig. 2 A.

Number in the figure: 1 window frame, 2 sash, 3 hinges, 4 pressure control lines, 5 fixtures, 6 caesium potash glasses, 7 shapes.

Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

The specific embodiment:

Embodiment: referring to Fig. 1-Fig. 2 B, the described wire controlled communications equipment room energy-saving pressure release window of present embodiment, comprise window frame 1 and sash 2, the base of sash 2 is articulated on the window frame by hinge 3, the top of sash is connected by the fixture 5 of a close indoor side on pressure control line 4 and the window frame, shown in Fig. 2 A, fixture is the section bar of one " L " shape, it is fixed in window frame on one side near on the body of wall of an indoor side, another side protrudes in the lower edge of window frame top margin, one end of pressure control line 4 is fixed on the fixture, and the other end is fixed on the sash top margin near an indoor side, shown in Fig. 2 B, when indoor pressure meets or exceeds design load, the pressure control line fracture, sash is opened, to reach the purpose of pressure release.The design formulas of pressure control line breakaway poing is as follows: environment stress P * sash area S/2 in pressure control line breakaway poing control intensity F (K)=fire district.

Shown in Fig. 2 A, sash 2 is made of the caesium potash glass 6 of bilayer and the shape 7 that is fixedly arranged on around the double-deck caesium potash glass, according to indoor heat insulation different demands, forms vacuum between the two-layer caesium potash glass or does not form vacuum.
