In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " horizontal ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " is based on accompanying drawing institute
The orientation for showing or position relationship, are for only for ease of description this utility model and simplify description, rather than indicate or imply indication
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The restriction of novel protected scope.
Below in conjunction with the accompanying drawings 1 to Fig. 6 is described in further details to this utility model flame tube head gap measuring apparatus.
This utility model provides a kind of flame tube head gap measuring apparatus, including the positioning pipe 1 and measurement that are nested
Pipe 2.
Positioning pipe 1 is the rounded straight tube in section, and the external diameter of positioning pipe 1 is equal to the minimum of the Venturi tube 31 of flame tube head
Internal diameter, the internal diameter of positioning pipe 1 can be arranged as required to be more than or equal to the external diameter of nozzle 36；In the present embodiment, such as Fig. 2 institutes
Show, the internal diameter of preferred orientation pipe 1 is equal to the external diameter of nozzle 36, so that positioning pipe 1 is fitted close with nozzle 36, raising is used
Stability.
Further, one end (bottom in Fig. 2) of positioning pipe 1 is co-axially located at text from flame drum tail after burner inner liner
In family name's pipe 31 is managed, and against on one end end face towards flame drum tail to one-level cyclone 32, now nozzle 36 projects one
The part (at tip position) of level cyclone is extend in positioning pipe.
In addition, positioning pipe 1 is from the beginning of one end end away from flame tube head, bar is in axial direction offered on tube wall
Shape through hole 11, and on strip through-hole 11 at the end face preset distance of one-level cyclone 32, with through hole enlarged portion 12, through hole expands
Open the width for being wider than strip through-hole 11 in portion 12.
Measurement pipe 2 is the rounded straight tube in section, and the external diameter of measurement pipe 2 is less than or equal to the internal diameter of positioning pipe 1 and is equal to
The external diameter of nozzle 36；Equally, the external diameter of preferred measurement pipe 2 is equal to the internal diameter of positioning pipe 1 in the present embodiment.
Further, pre-position is provided with the projection 21 matched with the size of strip through-hole 11 on the outer wall of measurement pipe 2,
And projection 21 can be in through hole enlarged portion 12 along sliding perpendicular to axial direction, measurement pipe 2 is arranged in positioning pipe 1, projection 21
