The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
Like Fig. 1 ~ shown in Figure 3: the utility model comprises that cylindrical shell 1, first cover plate 2, piston 3, regulating spring 4, linear bearing 5, slide bar 6, the gas port 7 that overflows, housing 8, first regulate cavity 9, second cover plate 10, pore 11 and second and regulate cavity 12.
Like Fig. 1, Fig. 2 and shown in Figure 3: said housing 8 comprises cylindrical shell 1, and said cylindrical shell 1 is cylindric, and the two ends of cylindrical shell 1 are provided with first cover plate 2 and second cover plate 10 respectively, said first cover plate 2 and second cover plate 10 and cylindrical shell 1 corresponding matching.Cylindrical shell 1 is a hollow-core construction, and the cylindrical shell 1 and first cover plate 2, second cover plate, 10 corresponding matching form the pressure compensation cavity in housing 8.Be provided with piston 3 in the housing 8, said piston 3 is divided into first of relative closure with the pressure compensation cavity in the housing 8 and regulates the cavity 9 and the second adjusting cavity 12, and promptly the first adjusting cavity 9 and second is regulated and is not communicated with after cavity 12 is isolated through piston 3.
Some evenly-distributed air holes 11 are set on first cover plate 2, and said pore 11 and second is regulated cavity 12 and is connected.Housing 8 is corresponding to being provided with some equally distributed excessive gas ports 7 on the outer peripheral face that forms the first adjusting cavity 9, and said excessive gas port 7 and first is regulated cavity 9 and is connected.Particularly, four equally distributed excessive gas ports 7 are set on the housing 8.First of housing 8 correspondences are regulated in the cavity 9 and are provided with regulating spring 4, and an end of said regulating spring 4 is fixedly connected with second cover plate 10, and the axis of the axis of regulating spring 4 and housing 8 is consistent.
Said piston 3 is installed on the slide bar 6 through linear bearing 5, and the two ends of said slide bar 6 are fixedly connected with first cover plate 2 and second cover plate 10 of housing 8, and the axis of the axis of slide bar 6 and housing 8 is located along the same line.Regulating spring 4 links to each other with piston 3 through linear bearing 5 corresponding to the other end that links to each other with second cover plate 10, and linear bearing 5 can slide on slide bar 6.When piston 3 slided on slide bar 6 through linear bearing 5, piston 3 was through linear bearing 5 compression or stretching regulating springs 4.When piston 3 slides on slide bar 6 through linear bearing 5; Piston 3 can be to the direction motion near second cover plate 10; During along with the continuous motion of piston 3, piston 3 is gradually near excessive gas port 7, piston 3 can with excessive gas port 7 corresponding matching; Make excessive gas port 7 to be connected, keep the stability of positive negative pressure with pore 11.
Like Fig. 1 ~ shown in Figure 3: during use, the positive negative pressure compensation arrangement that the utility model all is set at the malleation and the negative pressure mouth of blower fan; When blower fan is in negative pressure state, the malleation port closing; When blower fan is in barotropic state, the negative pressure port closing.When blower fan is in negative pressure state, and when needing to keep negative regulation, the negative pressure mouth links to each other with excessive gas port 7 on the housing 8.When initial, overflow 11 at gas port 7 and pore pass through to isolate.Along with the continuous increase of negative pressure, the active force that negative pressure produces makes piston 3 to the direction motion near second lid 10, when negative pressure increases to analog value; Piston 3 can be crossed the gas port 7 that overflows; The gas port 7 that make to overflow is connected with pore 11, and air-flow can inject second through pore 11 to be regulated in the cavity 12, make pore 11 as malleation mouth accordingly; Keep the malleation mouth of blower fan and the state of negative pressure mouth, reach the purpose that keeps negative regulation property.When action of negative pressure power disappeared or diminishes, piston 3 to the direction motion near first lid 2, was regulated being communicated with of overflow gas port 7 and pore 11 under the effect of regulating spring 4, until not being communicated with of excessive gas port 7 and 11 at pore.
In like manner, when said positive negative pressure compensation arrangement matched with the malleation outlet, the pore 11 on first cover plate 2 linked to each other with the outlet of the malleation of blower fan, and when initial, piston 3 is isolated the connected state of pore 11 and excessive gas port 7.When blower fan is in the malleation duty, need to form corresponding negative pressure mouth through the gas port 7 that overflows.Particularly, the blower fan malleation acts on the piston 3 through pore 11, along with continual malleation; Piston 3 moves to second cover plate, 10 directions on slide bar 6 through linear bearing 5 under positive pressure; After piston 3 moved, piston 3 meeting compression adjustment springs 4 moved to gas port 7 places of overflowing until piston 3; Make excessive gas port 7 be connected with pore 11, air-flow can inject second through the gas port 7 that overflows and regulate the cavity 12 interior stability that keep the blower fan malleation.When the active force of malleation disappeared or diminishes, piston 3 to the direction motion near first lid 2, was regulated being communicated with of overflow gas port 7 and pore 11 under the effect of regulating spring 4, until not being communicated with of excessive gas port 7 and 11 at pore.
One end of the utility model housing 8 is provided with pore 11, and the outer peripheral face of housing 8 is provided with the gas port 7 that overflows; Be provided with the piston 3 that can regulate pore 11 and excessive gas port 7 connected states in the housing 8, piston 3 is installed on the slide bar 6 through linear bearing 5, and slide bar 6 is installed in the housing 8; Be with regulating spring 4 on the slide bar 6, an end of regulating spring 4 links to each other with piston 3 through linear bearing 5, and the other end is fixedly connected with housing 8; When needs were regulated positive negative pressure, the positive and negative living active force of cutting down output acted on the piston 3, piston 3 meeting compression adjustment springs 4; And to direction motion near the gas port 7 that overflows; Until making excessive gas port 7 be connected with pore 11, reached the purpose of regulating positive negative pressure, keep the stability of required positive negative pressure; After regulating completion, piston 3 resets under the effect of regulating spring 4, and isolated pore 11 is communicated with excessive gas port 7; Simple and compact for structure, easy to install, energy-conserving and environment-protective reduce use cost, guarantee the stability of positive negative pressure, and are safe and reliable.
