Abstract
The utility model discloses a shrinkage cavity door that two cores are adjustable, it relates to power plant buggy equipment technical field for the pipeline, install interface round flange and interface square flange on the casing respectively, the door body passes through interface round flange, interface square flange and power plant's buggy pipe connection, and the core is installed in the inside of casing, and the lower surface of core is supported by the track roller, and the upper surface and interface nozzle stub cooperation, the positive back drive lead screw of core are installed in double cannula sealing device, and just positive back drive lead screw is being connected with the core, the utility model provides the regulation sensitivity of product has been guaranteed to the high flexibility of operation of long -time running equipment, has improved the use reliability of product.
Description
Technical field
The utility model relates to pulverized coal in power plant pipeline equipment technical field, is specifically related to a kind of Double core adjustable pipe door.
Background technique
At present, the structure of thermoelectricity plant's pulverized coal channel adjustable contraction adopts: case panel composition rectangular box, two ends short tube welds with panel, the chamber at driving mechanism place and the isolation of coal dust adopt central layer surrounding to install flexible graphite stuffing additional, long-time running graphite packing is easily blown mistake, produces after leaking powder and causes driving mechanism switch bite; Outlet port is rectangle square chest, easily produces accumulated powder and causes central layer switch unsmooth; Outlet stubs circles round because of MEDIA FLOW and causes eccentric wear; Easily leaked by mill after the central layer long-time running of hollow, cause running state deterioration etc.
Summary of the invention
The purpose of this utility model is defect for prior art and deficiency, provides a kind of Double core adjustable pipe door.
In order to solve the problem existing for background technique, a kind of Double core adjustable pipe door of the present utility model, it comprises housing, central layer, short port tube, interface round flange, forward and reverse driving screw mandrel, interface method orchid; Housing is separately installed with interface round flange and interface method orchid, door body is connected with power plant pulverized coal channel by interface round flange, interface method are blue, central layer is arranged on the inside of housing, the lower surface of central layer is supported by track roller, the upper surface of central layer coordinates with short port tube, forward and reverse driving screw mandrel is arranged in double-jacket tube seal arrangement, and forward and reverse driving screw mandrel is connected with central layer.
The utility model beneficial effect is: the operating flexibility that improve long-time running equipment, ensure that the adjustment sensitivity of product, improves the operational safety of product.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-housing; 2-central layer; 3-short port tube; 4-interface round flange; The forward and reverse driving screw mandrel of 5-; 6-interface method is blue.
embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, this embodiment adopts following technological scheme: it comprises housing 1, central layer 2, short port tube 3, interface round flange 4, forward and reverse driving screw mandrel 5, interface method orchid 6; Housing 1 is separately installed with interface round flange 4 and interface method orchid 6, door body is connected with power plant pulverized coal channel by interface round flange 4, interface method blue 6, central layer 2 is arranged on the inside of housing 1, the lower surface of central layer 2 is supported by track roller, the upper surface of central layer 2 coordinates with short port tube 3, forward and reverse driving screw mandrel 5 is arranged in double-jacket tube seal arrangement, and forward and reverse driving screw mandrel 5 is connected with central layer 2.
Further, described housing 1 is the two pieces of panels that will be arranged in parallel, and retain one side, another side does funneling and makes.
The working principle of this embodiment is: during adjustment: by shake live axle, through sprocket wheel chain, drive forward and reverse driving screw mandrel 5, flexible-core plate 2 folding is with by forward and reverse driving screw mandrel 5, adjustment area of passage, thus the object reaching adjustment pipeline flow, pressure.During installation, funnel one is facing to air intake surface, and coal dust does not collect and stays in cavity, and driving component is in double-jacket tube simultaneously, does not affect by accumulated powder, ensures the reliability of use.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
