This check valve adopts the metal material to make, and installs firebreak device, has good fire behavior, secondly, two metal non return pieces pass through the connecting axle to be connected, and the design is nimble, can open totally and close, improves the ventilation effect, be equipped with the leak protection strip of paper used for sealing in the metal cylinder of this check valve, be equipped with the base sealing strip on the base, can further improve sealed effect.
Description
Technical field
The utility model relates to a kind of safety check, particularly relates to a kind of engineering metal safety check.
Background technique
Engineering safety check is different from common family expenses safety check, it is all had higher requirement to the unlatching effect, fireproof performance, sealing effect etc. of non-return sheet, and there is many defects in current engineering safety check, such as, non-return sheet can only open a part, all can not open, have impact on the ventilation effect in same equal time thus; For another example, though arrange refractory protection, complex structure, fabricating cost is high; Meanwhile, flue taint of odour phenomenon happens occasionally, especially for market or the food and beverage sevice place of shopping diet consumption integration, and the desire for consumer goods of the large holocaust Consumer of meeting, and then affect the volume of the flow of passengers in such place.
Therefore, above-mentioned technical barrier urgently to be resolved hurrily.
Model utility content
Model utility object: the purpose of this utility model is to provide a kind ofly has fireproof performance and the good fire-fighting metal safety check of ventilation effect.
Technological scheme: safety check described in the utility model, comprise metal installation base and be positioned at the metal cylinder in this metal installation base, the symmetrical metal non-return sheet installed two panels and can open completely in metal cylinder, this two panels metal non-return sheet is connected by coupling shaft, establishes refractory protection in the coupling shaft position near metal cylinder inwall.
Wherein, described refractory protection comprises to be located in metal installation base and to bend the first link extending to metal cylinder side, supporting post is established between the first link and coupling shaft, on this supporting post, cover has spring, and install for preventing recoil of spring to the fuse link of metal non-return sheet on the supporting post close to coupling shaft position, this fuse link is connected with the first link by the second link simultaneously.
Furtherly, leakage strip of paper used for sealing of setting up defences between above-mentioned coupling shaft and metal cylinder inwall, can improve the sealability of safety check.
Meanwhile, the plane of described metal non-return sheet and Vertical direction have the angle of 25-40 degree, and during to ensure that safety check does not use, two non-return sheets are in closed state.
In addition, the surrounding of described metal installation base is provided with square groove, is provided with base seal bar in this square groove.Described metal installation base is provided with metal spring folder, to fixedly mount safety check.
Beneficial effect: compared with prior art, its advantage adopts metal material to make for this safety check to the utility model, and is provided with refractory protection, has good fireproof performance; Secondly, two panels metal non-return sheet is connected by coupling shaft, and flexible design, can open and close completely, improves ventilation effect; Be provided with leakproof strip of paper used for sealing in the metal cylinder of this safety check, base is provided with base seal bar, can further improve sealing effect.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model safety check;
Fig. 2 is the side view of the utility model safety check;
Fig. 3 is the plan view of the utility model safety check.
Embodiment
As Figure 1-3, safety check of the present utility model is made by metal material, the metal cylinder 2 comprising metal installation base 1 and be positioned in this metal installation base 1, symmetrical installation two panels metal non-return sheet 3 in metal cylinder 2, this two panels metal non-return 3 is connected by coupling shaft 4, non-return sheet can be opened completely, improve ventilation effect, install refractory protection 5 in coupling shaft 4 position near metal cylinder 1 inwall, wherein, if refractory protection position is placed in the middle, the activity of non-return sheet 3 can be affected.
Refractory protection 5 comprises the first link 6, second link 10, supporting post 7, be sheathed on the spring 8 etc. on supporting post 7, wherein, first link 6 is located in metal installation base and bending extends to metal cylinder side, similar " second " font, supporting post 7 is established between the first link 6 and coupling shaft 4, on this supporting post 7, cover has spring 8, the length of spring 8 is longer, if do not adopt foreign object to push down, can directly bullet on non-return sheet, therefore close to the supporting post 7 of coupling shaft position being installed for preventing recoil of spring to the fuse link 9 of metal non-return sheet, this fuse link 9 is connected with the first link 6 by the second link 10 simultaneously.Here fuse link uses iron plate usually.
To set up defences between above-mentioned coupling shaft 4 and metal cylinder 2 inwall Lou strip of paper used for sealing 11, the sealability of safety check can be improved.Leakproof strip of paper used for sealing 11 is generally iron plate, is welded between coupling shaft and barrel.
The plane of metal non-return sheet and Vertical direction have the angle of 25-40 degree, and during to ensure that safety check does not use, two non-return sheets lean against on cylinder inboard wall due to the effect of gravity, and thus, safety check is in closed condition.
The surrounding of metal installation base 1 is provided with square groove, is provided with base seal bar 12 in this square groove, due to the effect of this base seal bar 12 after installation, can improve sealing effect further, prevent smoke blowing taint of odour.
Metal installation base 1 is provided with metal spring folder 13, to fixedly mount safety check.
Working procedure: first by metal spring folder, fire-fighting metal safety check is contained on metope, and adjusts its mounting point.When safety check is opened, two panels non-return sheet side direction all opens combustion gas; When the check valve is closed, non-return sheet falls after rise in cylindrical shell obliquely by self gravitation; When in flue, temperature is too high, fuse link melts, and recoil of spring is on non-return sheet, and non-return sheet is closed, and occurs to avoid fire.
