Description
Technical field
The utility model relates to firefighting security device technical field, especially relates to a kind of fire-fighting fire-proof valve novel seal.
Background technique
Fire-fighting fire-proof class valve mainly comprises fire-closing valve, exhaust smoke valve, smoke exhaust fire damper.Fire-closing valve is mounted on ventilation, the sending of air-conditioning system, air return pipeline, is opening state at ordinary times, when fire occurs, automatically closes when gas in pipelines temperature reaches 70 DEG C.For all kinds of building, especially tall building, due to the effect of heat smoke high stack effect, once breaking out of fire, fire and smoke spread is rapid.Numerous fire cases shows, flue gas affects evacuating personnel in fire, and the main factor of fire-fighting and rescue, is also the most important reason causing casualties in fire.And intricate in building, that the pipeline of various ventilation and air-conditioning system that is that distribute in length and breadth becomes fire and smoke spread in fire main path, therefore the pipeline of ventilation and air-conditioning system must be cut off in time when fire occurs, to stop the passage of fire or fire and smoke spread, fire-closing valve is exactly a kind of actively, the effective fire fighting device be arranged on to function as described above in ventilation and air conditioning system.Exhaust smoke valve is generally arranged on the airduct of purging system, and at ordinary times during normally closed breaking out of fire, Smoke Detector sends signal, and control centre energising DC24V, to electromagnet on valve, valve is opened rapidly, or people manually opens rapidly valve and discharges fume.Smoke exhaust fire damper is generally arranged on the airduct of purging system, often opens at ordinary times, when flue temperature is closed automatically to when 280 DEG C, and hand reset.
Fire prevention class valve requires to have Fire stability, Fire integrity, good sealing property, keying flexibility.Valve is under high temperature action, and blade and sharf, because of material behavior, have certain thermal expansion amount, in order to ensure valve opening and closing flexibility, must reserve certain gap between blade and valve body.Then the sealing of valve just cannot ensure, when breaking out of fire, valve effectively cannot stop fire and smoke spread.
Model utility content
In order to overcome above-mentioned existing technological deficiency, it is simple, easy to make, quick for installation that the purpose of this utility model is to provide a kind of structure, the fire-closing valve closed of good airproof performance.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
The technical program is a kind of fire-fighting fire-proof valve novel seal, comprises blade, stiffening rib and side blend stop; Arrange latch plate between described vane end faces and stiffening rib, described latch plate is engaged and installed on stiffening rib, and latch plate engages with stiffening rib through sharf; Side blend stop is fixedly mounted on valve body, described side blend stop fixedly mounts the profiled seal bar under being tilted to; Described latch plate outer surface is cambered outwards circular arc plate; Described latch plate and profiled seal bar are all stainless steel material and make.Vane end faces and stiffening rib contacting point adopt latch plate to seal, latch plate outer surface is cambered outwards circular arc, make the arc-shaped structure of vane end faces and latch plate form linear contact lay, reduce frictional force that blade closes the simultaneously blade rotation that reduces wear and ensure excellent sealing more flexibly simultaneously.Side blend stop fixedly mounts profiled seal bar and profiled seal strip adoption stainless steel is made so have certain elasticity, after blade deforms by high temperature, to blade, there is compensating action.Latch plate and different in nature sealing strip material are stainless steel, have good intensity, rigidity, resistance to heat is stable and quality is light, easily mount and dismount.
As optimization, the angle that described profiled seal bar is tilted to lower layout is 15 ° to 30 °, and different in nature Stamping Steel Ribbon angle of inclination is arranged in be formed between blade side and side blend stop after blade deforms and compensates, and ensures sealing.
Compared with prior art, the beneficial effects of the utility model are: the utility model ensure that the Fire stability of valve, Fire integrity, good sealing property, keying flexibility; Latch plate, profiled seal bar structure are simple, and practical, easy for installation, heat resistance is good, can effectively play isolated air effect when breaking out of fire, stop fire and smoke spread.

Mark in figure: blade 1, stiffening rib 2, side blend stop 3, latch plate 4, profiled seal bar 5 and sharf 6.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, and as shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4, the utility model is a kind of fire-fighting fire-proof valve novel seal, comprises blade 1, stiffening rib 2 and side blend stop 3; Arrange latch plate 4 between described blade 1 end face and stiffening rib 2, described latch plate 4 is engaged and installed on stiffening rib 2, and latch plate 4 engages with stiffening rib 2 through sharf 6; Side blend stop 3 is fixedly mounted on valve body, described side blend stop 3 fixedly mounts the profiled seal bar 5 under being tilted to; Described latch plate 4 outer surface is cambered outwards circular arc plate; Described latch plate 4 and profiled seal bar 5 are all stainless steel material and make.
Blade 1 end face and stiffening rib 2 contacting point adopt latch plate 4 to seal, latch plate 4 outer surface is cambered outwards circular arc, the arc-shaped structure of blade 1 end face and latch plate 4 is made to form linear contact lay, ensure excellent sealing, the frictional force reduced when blade is closed reduces wear and makes blade rotation more flexible simultaneously.Because arc structure short transverse defines certain interval between latch plate 4 and stiffening rib 2, along with being out of shape together, the abundant laminating between blade 1 end face and latch plate 2 can be ensure that, good airproof performance at blade 1 expanded by heating rear spring plate 2; Valve is not when being heated, and blade 1 replys former state, and latch plate 4 gets back to initial position because of elastic force effect.The fire-closing valve rear blade 1 that is heated deforms, now when blade 1 and blend stop 3 bad connection of valve body side, easily cause leakage, side blend stop 3 fixedly mounts inclination profiled seal bar 5 and profiled seal bar 5 adopts stainless steel to make so have certain elasticity, after blade 1 deforms, to blade 1, there is compensating action.Latch plate 4 and different in nature Stamping Steel Ribbon 5 material are stainless steel, have good intensity, rigidity, resistance to heat is stable and quality is light, easily mount and dismount.Fireproof valve body improves the sealing configuration with blade 1 end face and contacts side surfaces position, ensure that the sealability that fire-closing valve is good.
Embodiment 2, the basis of embodiment 1 is optimized design to the angle that profiled seal bar 5 is in tilted layout, the angle that described profiled seal bar 5 is tilted to lower layout is 15 ° to 30 °, opposite sex Stamping Steel Ribbon 5 angle of inclination is arranged and be ensure that to be formed between blade 1 side and side blend stop 5 after blade 1 deforms and compensates, and guarantee seals.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
