Description
Technical field
The invention belongs to Industrial Boiler Technology field, particularly a kind of smoke sampling sealing device.
Background technology
The sample analysis of fired power generating unit exhaust gas components are to monitor one of important test event of unit runnability.But institute
The pressure different surveyed inside and outside flue, if do not sealed to gaging hole during testing, will certainly produce to measurement result
Considerable influence.Current sealing means are to block to be sealed during testing using soup cloth by gaging hole.But, it is this traditional
There are many drawbacks in sealing means：1. seal process is troublesome, and generally needing during sealing can be by soup cloth by hard stick-like object
Gaging hole is blocked gaging hole completely, if run into can be more difficult for barotropic condition seal process at gaging hole；2. at sealing between soup cloth
When be commonly present gap, cause can still the presence of impact measurement result of leaking out on a small quantity；3. if necessary to move in gaging hole during testing
Probe tube carries out multimetering, the situation for the loosening of soup cloth often occur, then again gaging hole will be sealed.
The content of the invention
The purpose of the present invention is, for the deficiencies in the prior art, and to propose a kind of smoke sampling sealing device.
The present invention solves its technical problem and takes technical scheme below to realize：
A kind of smoke sampling sealing device, including cylindrically shaped outer layer sleeve, are formed with and are arranged in one end of outer layer sleeve
The internal thread spun by base on flue, is coaxially fixedly mounted with internal layer in the inside of outer layer sleeve and wears cylinder, and internal layer wears one end of cylinder
Flush with outer layer sleeve, the other end is located at the internal start of outer layer sleeve internal thread, is worn on the side wall of cylinder vertically in internal layer
Arrangement, is formed respectively with multigroup perforation for pointing to axis, and per group of perforation is equal subangle and the multiple perforation perpendicular to axis, every
Decorative pearl on top of an official cap spring being installed in individual perforation, the decorative pearl on top of an official cap being connected with the medial extremity of decorative pearl on top of an official cap spring, the front side of the decorative pearl on top of an official cap is opened by the inside bored a hole
At mouthful, part is exposed, and is that the arcuation of interior receipts closes up at the inside opening of perforation, and closing in diameter is less than perforation interior diameter, the arc of interior receipts
Shape closes up and stops the decorative pearl on top of an official cap abjection being arranged in perforation, wears in internal layer and be bonded with the inwall of cylinder one layer of felt, in felt correspondence
Decorative pearl on top of an official cap perforate is formed with the position of each decorative pearl on top of an official cap.
And, thickness and the decorative pearl on top of an official cap of the felt expose internal layer and wear the highly identical of an inwall.
And, multigroup perforation for pointing to axis is even away from spaced four groups.
And, described per group equal subangle and perpendicular to axis multiple perforation be specially per group of perforation be mutually 90 for four
Spend and perpendicular to the perforation of axis.
Advantages of the present invention and good effect are：
The present invention is to develop a kind of smoke sampling sealing device, and the sealing device need to only be screwed on gaging hole base, will take
Can be used directly in sample pipe insertion sealing device, simple to operate, sealing effectiveness is good, during the preparation that can be saved before a large amount of tests
Between, while reducing the impact to test result of leaking out.
