Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is to this hair
Bright explanation and the invention is not limited to following embodiments.
Embodiment.
Referring to Fig. 1.
The present embodiment be a kind of sweeping steam pipeline target plate device, including target plate axis 2, Glan set 3, Glan lid 4 and with
The target plate casing 1 to be linked together by the interim gland steam exhauster of purging pipeline.Target plate casing 1 passes through with by the interim gland steam exhauster of purging pipeline
It is welded together, the nominal diameter of target plate casing 1 is equal with by the nominal diameter of the interim gland steam exhauster of purging pipeline.Glan set
3 and Glan lid 4 be the structure type with short tube and the flange plate faying face being connect with short tube.
In the present embodiment, the through hole perpendicular with its axial direction is offered on target plate casing 1, the both ends of the through hole are welded
Glan set 3 is connect in succession.Both direction is opened up on target plate axis 2 on the contrary and not in the target plate slot 9 of sustained height, the slot bottom of target plate slot 9
Countersunk screw holes 8 are offered on face, and target plate is fixed in target plate slot 9 by counter-sunk screw.The length of target plate slot 9 should traverse target plate
1 internal diameter of casing, width >=25% target plate casing, 1 diameter, depth, which should ensure that, can guarantee that target plate axis 2 is easily altered when cold conditions is packed into target plate
It is dynamic；Since target plate is different with 2 material of target plate axis, the coefficient of expansion is different, therefore circular screwhole should be processed in the middle part of target plate, two sides processing
Oval screw hole, it is ensured that free wxpansion under target plate high temperature, and the screw hole opened up on target plate should be counter sink, guarantee counter-sunk screw head
Without exposed gap between target plate, avoid leading to screw loosening because gap steam enters, target plate falls off, in addition, target plate meets steam side
It should polish on one side, it is ensured that be easy to examine purging effect after purging.
In the present embodiment, target plate axis 2 passes through Glan set 3 and through hole, and is positioned by Glan lid 4, after positioning, until
A rare target plate is located in the through hole of target plate casing 1.In order to realize sealing, prevents steam from leaking out along target plate axis, scald work
Make personnel, filling indentation graphite packing 5, graphite packing 5 should be layered indentation and cut at the faying face of Glan set 3 and target plate axis 2
Mouth should be staggered.
In the present embodiment, the both ends of target plate axis 2 are respectively provided with the thin axis that one section of cross section is square, thin axis and Glan
Location hole 10 is provided on the short tube of lid 4, by realizing to target plate axis 2 and Glan lid 4 toward the inner insertion positioning pin of location hole 10
Positioning.Glan set 3 and Glan lid 4 are fastenedly connected by bolt 6 and nut 7, are offered on the plate faying face of Glan set 3 recessed
Slot is welded with shaft 11 in groove, and an end cap of bolt 6, and can 11 rotation around the shaft in shaft 11.
In the present embodiment, referring to Fig. 1, to extract it is purged positioned at the first target plate of upper end when, by 2 upper end of target plate axis
The positioning pin in portion is extracted out, is tapped after target plate installed and alter axis in place with hammer from the lower end of target plate axis 2, is clamped target with open-end wrench
Then target plate axis 2 is rotated 180 ° and adjusts target plate position, it is ensured that the second target positioned at lower end by the thin axis of 2 lower end of board shaft
Plate face steam direction can remove the first target plate at this time and carry out inspection then to the positioning finger setting of 2 lower end of target plate axis.
Target plate device only need to weld again target plate casing 1, looser a bolt 6, nut 7, light with hammer when reusing
Strike nut 7, bolt 6, nut 7 slip, and remove Glan lid 4, dig out old graphite packing and restore after the new packing that changes the outfit Glan lid 4 and
It can.
In addition, it should be noted that, the specific embodiments described in this specification, the shape of parts and components are named
Title etc. can be different, and above content is only to structure of the invention example explanation described in this specification.It is all according to
According to equivalence changes or simple change that the structure, feature and principle that the invention patent is conceived is done, it is included in of the invention special
In the protection scope of benefit.Those skilled in the art can do described specific embodiment various
The similar mode of modify or supplement or adopt substitute, without departing from structure of the invention or surmount the claims institute
The range of definition, is within the scope of protection of the invention.
