The utility model has the advantages of it is following and effect: the new mechanical structure of this scheme utilization adopts blade closing rapidly when the conflagration takes place, and the head clamp of elastic component on with the blade promoted to imbed when the blade was closed totally in the draw -in groove, making blade positioning can not take place the bounce -back, can not forming the clearance that dense smoke spills over owing to the bounce -back of blade, when reaching the blade closure do not rebound in the location, uses safer effect.
Description
Technical field
This utility model relates to fire equipment field, particularly to a kind of fire-preventino regulating valve.
Background technology
Fire-preventino regulating valve is arranged on ventilation, the sending of air handling system, return air duct, at ordinary times in opening, closes during fire, and can meet leakage smoke and fire integrity demands within a certain period of time, plays the effect every cigarette back-fire relief.
The Chinese patent " flange form smoke-and fire-proof regulating valve " of Publication No. CN203556074U discloses a kind of flange form smoke-and fire-proof regulating valve, including valve body, blade, valve body side is provided with actuator, heat detector and handle it is provided with in actuator, connected by bearing on described valve body and have several axles, being provided with blade on axle, one of them axle is connected with the handle in actuator, is connected by link gearing between several blades.
But above-mentioned fire-preventino regulating valve has the disadvantage in that fire-preventino regulating valve emergency cut-off when fire occurs, blade rotates rapidly Guan Bi, rebounds after in bigger speed impacts to valve body, and blade and valve interior wall exist for the gap that dense smoke overflows, and there is peace hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of fire-preventino regulating valve, positions, after having blade Guan Bi, the effect not rebounded.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of fire-preventino regulating valve, including valve body, the blade that is rotationally connected with described valve body, described valve interior wall is provided with draw-in groove, described blade is provided with valve interior wall sliding be arranged at the head clamp in described vane end faces, described blade of completely closed time for the elastic component promoting described head clamp to embed described draw-in groove.
By using technique scheme, blade rapid closing when fire occurs, when blade is of completely closed, the head clamp on blade is promoted and embeds in described draw-in groove by elastic component, makes blade location to rebound, will not form, due to the bounce-back of blade, the gap that dense smoke overflows, use safer.
Of the present utility model it is further arranged to: be provided with the described valve interior wall chute for described head clamp sliding on described blade, described head clamp is integrally formed with the slide block being matched with described chute.
By using technique scheme, slide block on head clamp embeds in chute, makes the head clamp can be towards valve interior wall sliding.
Of the present utility model being further arranged to: described vane end faces is provided with fixed block, described elastic component is that one end is fixedly connected on described clamping and the other end is fixed on the spring of described fixed block.
By using technique scheme, spring one end is fixed on the fixed block on blade, one end is fixed on head clamp, when spring produces elastic force, promotes head clamp sliding on blade, when blade is of completely closed, the front end of head clamp is positioned on draw-in groove, during under the effect of spring force, head clamp embeds draw-in groove, head clamp positions relative to valve body, owing to head clamp is arranged on blade, make blade be positioned, will not rebound.
Of the present utility model it is further arranged to: during described blade Guan Bi, described head clamp is provided with and is connected to described valve interior wall and guides described head clamp compress the spigot surface of described elastic component away from valve interior wall.
By using technique scheme, when blade proceeds in valve body, head clamp is connected to valve interior wall, head clamp is guided sliding away from valve interior wall by spigot surface, making elastic component be compressed generation elastic force, when blade is of completely closed, head clamp is on draw-in groove, under the effect of elastic force, head clamp is pushed into draw-in groove, and head clamp is positioned by draw-in groove.
Of the present utility model it is further arranged to: described spigot surface is arc.
By using technique scheme, the less friction of spigot surface of arc, make head clamp be connected to during valve interior wall and make head clamp sliding away from valve interior wall, compression elastic piece.
Of the present utility model it is further arranged to: described draw-in groove inwall is provided with for sealing the sealing gasket in gap between described head clamp and described draw-in groove.
By using technique scheme, time in head clamp embedding draw-in groove, sealing gasket makes draw-in groove be in sealing state between head clamp, and fire-preventino regulating valve can produce the effect of secondary seal.
Of the present utility model it is further arranged to: described blade is provided with for sealing the sealant in gap between described head clamp and described blade.
By using technique scheme, being in sealing state between head clamp and blade, dense smoke is again sealed off by the sealant being clamped between plate and blade after the sealing between blade and valve interior wall, improves the flameproof effect of fire-preventino regulating valve further.
In sum, this utility model has the advantages that and makes blade will not rebound when promptly rotating Guan Bi by the cooperation of head clamp and draw-in groove, after blade rotates Guan Bi, the position of blade is locked by head clamp, the fire-preventino regulating valve turned off is locked, will not be opened under acting on due to air pressure, object shock etc., close more firm in the accidents such as fire, promote the fire protecting performance of fire-preventino regulating valve further.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
nullA kind of fire-preventino regulating valve，As shown in Figure 1，Including valve body 1、Internally positioned blade 2，When fire-preventino regulating valve is closed, blade 2 rotates Guan Bi，Make dense smoke、Flame etc. do not pass through fire-preventino regulating valve diffusion，As shown in Figure 2，The chute 21 of valve body 1 inwall it is provided with on blade 2 end face，The head clamp 3 being positioned at blade 2 end face it is additionally provided with on blade 2，As shown in Figure 3，In conjunction with Fig. 4，Slide block 32 it is integrally formed with on head clamp 3，When slide block 32 embeds in chute 21，Head clamp 3 can slide along chute 21 towards valve body 1 inwall，It is additionally provided with on blade 2 for sealing the sealant 6 in gap between head clamp 3 and blade 2 end face，The fixed block 22 being perpendicular to blade 2 end face it is additionally provided with on blade 2，Fixed block 22 is provided with elastic component 4，Elastic component 4 uses spring 41，One end of spring 41 is fixed on head clamp 3，The other end is fixed on fixed block 22.When blade 2 is rotated in valve body 1, one end of head clamp 3 is provided with the spigot surface 31 of contact valve body 1 inwall, and spigot surface 31 is arc, after the spigot surface 31 of arc contacts valve body 1 inwall, by head clamp 3 along chute 21 sliding away from valve body 1 inwall, makes elastic component 4 be compressed；Valve body 1 inwall is additionally provided with draw-in groove 11, draw-in groove 11 inwall is provided with sealing gasket 5, when blade 2 is of completely closed, head clamp 3 front end is positioned on draw-in groove 11, the elastic component 4 now compressed produces elastic force and pushes in draw-in groove 11 by head clamp 3, head clamp 3 embeds in draw-in groove 11, location head clamp 3 and blade 2, makes blade 2 will not rebound when promptly closing.
