Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model utilizes triangular prism back near the steam flow stagnant area two groove face groove faces in flow field, makes this faceted pebble avoid steam flow not over against the steam flow direction time and washes away, can be correctly for check with the target plate that guarantees to be loaded on two groove surfaces; In its self sealing structure, encapsulant can be more closely knit under the effect of pressure, and the highly denser solidity of pressure is better, to reach the purpose that effectively prevents steam leakage.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, a kind of target plate device, comprise target axle handle 1, target axle 2, target axle pallet 3, sealed packing 4, target axial compression lid 5, target shaft packing letter 6 and target plate 7, target axle 2 is right cylinder, by top target axle, middle part target axle and bottom target axle form, target axle handle 1 is fixed on Ba Zhou end, top, top target axle the latter half is placed in target shaft packing letter 6, sealed packing 4 is placed between top target axle and target shaft packing letter 6, target axial compression lid 5 is positioned at target shaft packing letter 6 tops, fixing by four bolts and target shaft packing letter 6, bottom target axle is fixed in target axle pallet 3, middle part target axle is arranged in main pipeline, at middle part, target axle outer wall is axially offered three identical grooves along it, three groove groove face centers are equal to the distance in target axle axle center, middle part, two target plates 7 are embedded in respectively in groove, be provided with a circle boss 8 on the target axle of top, boss 8 is positioned at target shaft packing letter 6.The axial groove of middle part target axle, its groove depth is greater than target plate 7 thickness.The length of groove identical with middle part target axle axial length (be between its length between main pipeline internal diameter and external diameter), width is 8% of main pipeline diameter.Sealed packing 4 is between target axial compression lid 5 and boss 8.Under the effect of vapor pressure, boss 8 is compression seal packing 4 upwards, forms self sealss, has greatly improved the sealing effectiveness of whole device.
Target axle pallet 3 is welded on main pipeline; Target shaft packing letter 6 is welded on main pipeline.
The principle that realizes a double target plate check of voltage stabilizing washing pipe is as follows:
In conjunction with Fig. 4 to Fig. 6, the stage 1: before boiler startup, target plate device is installed, the groove face that is unkitted target plate is faced to steam flow, then start boiler voltage stabilizing washing pipe;
Stage 2: the bobbing target axle, in the face of steam flow, carry out target plate check for the first time by the first target plate 7-1;
Stage 3: bobbing target axle again, in the face of steam flow, carry out target plate check for the second time by target plate 7-2;
Stage 4: target plate test ending for the second time, the bobbing target axle, be unkitted the target plate groove face to steam flow again, and the boiler of then stopping transport takes out target plate.
In conjunction with Fig. 7, when the main pipeline diameter is not more than 600mm, target plate adopts fixing (being that two ends are fixed), target plate making circular hole at 2; When the main pipeline diameter is greater than 600mm, target plate adopts fixing (being that two ends add center) at 3, and target plate two ends employing strip hole, is beneficial to target plate and expands to two ends, to eliminate the target plate distortion.Target plate is bolted together on the faceted pebble (being target axle groove floor) of middle part target axle.In three grooves of middle part target axle, two groove groove faces putting target plate must be opened the fixedly bolt hole of target plate; And the groove groove face of not putting target plate both can have been opened the fixedly bolt hole of target plate, also can not open the fixedly bolt hole of target plate.But it should be noted: the faceted pebble do not put target plate if select is not opened the fixedly bolt hole of target plate yet, and its bolt hole is also applied in use identical bolt and sealed, in case steam flow is from the bolt hole importing and target plate is blown off.
