Abstract
The invention relates to a flue gas sampling sealing device. The flue gas sampling sealing device comprises an outer layer sleeve; internal threads are formed at one end of the outer layer sleeve; an inner layer penetrating cylinder is fixedly arranged in the outer layer sleeve; a plurality of groups of punched holes which point to a middle shaft are formed in the side wall of the inner layer penetrating cylinder along the axial direction; an ejector ball spring is arranged in every punched hole; the inner lateral end of every ejector ball spring is fixedly connected with an ejector ball; the front side of every ejector ball is exposed from an opening formed inside the corresponding punched hole; the opening formed inside every punched hole is an arc-shaped retracting opening which retracts inward; every arc-shaped retracting opening which retracts inward is used for preventing the ejector ball arranged in the corresponding punched hole from falling off; a layer of felt is adhesive to the inner wall of the inner layer penetrating cylinder; an ejector ball opening is formed at a position of the felt, wherein the position is corresponding to the corresponding ejector ball. A user can directly use the flue gas sampling sealing device by spirally twisted the flue gas sampling sealing device on a hole measurement pipe base and inserting a sampling pipe into the sealing device and accordingly the operation is simple, the sealing effect is good, the preparation time before a test can be saved, and the influence of air leakage on the test result is reduced.
Description
Technical field
The invention belongs to Industrial Boiler Technology field, particularly a kind of smoke sampling seal arrangement.
Background technique
The sample analysis of fired power generating unit exhaust gas components is one of important test event monitoring unit ride quality.But pressure inside and outside institute's survey flue different, if do not sealed gaging hole at test period, considerable influence will certainly be produced to measurement result.Current sealing means uses soup cloth to be blocked by gaging hole at test period to seal.But this traditional sealing means exists a lot of drawback: 1. seal process is very loaded down with trivial details, usually need during sealing gaging hole to be blocked gaging hole by soup cloth completely by hard rod shape object space, if running into gaging hole place is that barotropic condition seal process can be more difficult; 2. often there is gap between sealing place soup cloth, cause that still existing leaks out on a small quantity affects measurement result; 3., if test period needs mobile probe tube in gaging hole to carry out multi-metering, often there will be the situation that soup cloth loosens, then will again seal gaging hole.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, and propose a kind of smoke sampling seal arrangement.
The present invention solves its technical problem and takes following technological scheme to realize:
A kind of smoke sampling seal arrangement, comprise cylindrically shaped outer layer sleeve, the internal thread carrying out with the base be arranged on flue spinning is shaped with in one end of outer layer sleeve, coaxially be fixedly mounted with internal layer in the inside of outer layer sleeve and wear cylinder, one end that internal layer wears cylinder flushes with outer layer sleeve, the other end is positioned at the internal start place of outer layer sleeve internal thread, the sidewall wearing cylinder at internal layer arranges vertically, be shaped with the perforation that many groups point to axis respectively, often group perforation is for dividing equally angle and perpendicular to multiple perforation of axis, decorative pearl on top of an official cap spring is installed in each perforation, the decorative pearl on top of an official cap is connected with at 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 exposed by the inside opening part of boring a hole, the inside opening place of perforation is the arcuation closing in of adduction, closing in diameter is less than perforation inner diameter, the arcuation of adduction closes up and stops that the decorative pearl on top of an official cap be arranged in perforation is deviate from, the inwall wearing cylinder at internal layer is bonded with one deck felt, decorative pearl on top of an official cap perforate is shaped with in the position of the corresponding each decorative pearl on top of an official cap of felt.
And thickness and the decorative pearl on top of an official cap of described felt expose internal layer to wear the height of an inwall identical.
And the perforation that described many groups point to axis is even apart from spaced four groups.
And described often group is divided equally angle and is specially often group perforation perpendicular to multiple perforation of axis and is four and is mutually 90 degree and perpendicular to the perforation of axis.
Advantage of the present invention and good effect are:
The present invention is a kind of smoke sampling seal arrangement of development, and sealing device only need be screwed on gaging hole base, is inserted by probe tube in seal arrangement and can directly use, simple to operate, sealing effect is good, can save the setup time before a large amount of test, reduces simultaneously and leaks out on the impact of test result.
