Description

Target plate device
Technical field
The invention belongs to mechanical hook-up, be specifically related to a kind of target plate device, can be used for the check of voltage stabilizing washing pipe.
Background technology
Existing widely used target plate device is to excavate two target plate grooves in the same way a target axle side, and two target plate grooves adopt arranged in series, and reaching a target plate groove in trunk line, and another target plate groove is outside trunk line.When target plate device uses, with external force the target plate groove in the trunk line is released together with target plate, simultaneously that trunk line is outer target plate groove pushes trunk line together with target plate.The target axle is under the alternating action of two ends external force, and two target plate grooves alternately pass in and out trunk line together with target plate, carries out the washing pipe check to reach continuous replacing target plate.But when moving to the target plate groove by the trunk line tube wall because of the target axle, because there is gap in target plate groove place, a large amount of steam will be sprayed thus, and very easily injure operating personnel, therefore, this target plate device must just can carry out above-mentioned replacing target plate operation when steam stops to flow.
Summary of the invention
The object of the present invention is to provide a kind of target plate device, can be used for the check of voltage stabilizing washing pipe, provide a kind of new way for the voltage stabilizing of station boiler vapour system purges to check and accept.
The technical solution that realizes the object of the invention is: a kind of target plate device, comprise target axle handle, the target axle, target axle pallet, sealed packing, target axial compression lid, target shaft packing letter and target plate, the target axle is right cylinder, by top target axle, middle part target axle and bottom target axle are formed, target axle handle is fixed on the end of top target axle, top target axle the latter half places in the target shaft packing letter, sealed packing places between top target axle and the target shaft packing letter, target axial compression lid is positioned at target shaft packing letter top, fix by bolt and target shaft packing letter, bottom target axle is fixed in the target axle pallet, middle part target axle is arranged in trunk line, target axle outer wall is axially offered three identical grooves along it at the middle part, three groove groove face centers are equal to the distance in target axle axle center, middle part, target plate is embedded in the groove, is provided with a circle boss at top target axle, and boss is positioned at target shaft packing letter.
Groove on the target axle of above-mentioned middle part, its groove depth is not less than target plate thickness, the groove on the target axle of middle part, and its groove depth is not less than target plate thickness, the length of groove identical with middle part target axle axial length (be between its length between trunk line internal diameter and external diameter), width is the 7%-9% of trunk line diameter.
Above-mentioned target plate is two, is embedded in respectively in the groove, and sealed packing is between target axial compression lid and boss, and target axle pallet is fixed on the trunk line, and target shaft packing letter is fixed on the trunk line.
When trunk line diameter during greater than 600mm, target plate adopt 3 fixing, namely strip hole is adopted at two ends, the centre is circular hole.
In the time might spending greater than 450 by the vapor (steam) temperature of trunk line, this target plate device adopts alloy steel to make target plate device; When the vapor (steam) temperature by trunk line is not more than 450 when spending, this target plate device can adopt No. 20 carbon steel to make target plate device.
The present invention compared with prior art, its remarkable advantage: can test by double replacing target plate when present invention can be implemented in steam blowing; Its self sealing structure prevents steam leakage better, guarantees handling safety.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
The present invention 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, and can correctly be used for check with the target plate that guarantees to be loaded on two groove surfaces; Encapsulant can be more closely knit under the effect of pressure in its self sealing structure, and the more highly dense solidity of pressure is more good, 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 are formed, target axle handle 1 is fixed on the end of top target axle, top target axle the latter half places in the target shaft packing letter 6, sealed packing 4 places between top target axle and the 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 the target axle pallet 3, middle part target axle is arranged in trunk line, target axle outer wall is axially offered three identical grooves along it at the middle part, and three groove groove face centers are equal to the distance in target axle axle center, middle part, and two target plates 7 are embedded in the groove respectively, be provided with a circle boss 8 at top target axle, 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 trunk line internal diameter and external diameter), width is 8% of trunk line 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 improved the sealing effectiveness of whole device greatly.
Target axle pallet 3 is welded on the trunk line; Target shaft packing letter 6 is welded on the trunk line.
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 the boiler startup, target plate device is installed, the groove face that is unkitted target plate is faced steam flow, start boiler voltage stabilizing washing pipe then;
Stage 2: the bobbing target axle, in the face of steam flow, carry out the target plate check first time with the first target plate 7-1;
Stage 3: bobbing target axle again, in the face of steam flow, carry out target plate 7-2 second time target plate and check;
Stage 4: target plate test ending for the second time, the bobbing target axle is unkitted the target plate groove face to steam flow again, and the boiler of stopping transport then takes out target plate.
In conjunction with Fig. 7, when the trunk line diameter was not more than 600mm, target plate adopted fixing (being that two ends are fixed), target plate opened round hole at 2; When trunk line diameter during greater than 600mm, target plate adopts fixing (being that two ends add the center) at 3, and the target plate two ends adopt strip hole, is beneficial to target plate and expands to two ends, to eliminate the target plate distortion.Target plate is with on the faceted pebble (being target axle groove floor) that is bolted to 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: if the faceted pebble of selecting not put target plate is not opened the fixedly bolt hole of target plate yet, then its bolt hole is also used identical bolt in use and is sealed, in case steam flow is from the bolt hole importing and target plate is blown off.
