Abstract
The utility model discloses a hole plug of a flue dust sampling gun, which belongs to a mechanical plug body, and solves the problem that the flue dust sampling gun can not be tightly matched with a sampling hole. A plug body (3) is divided into a first plug body (9) and a second plug body (10) by a vertical surface passing through the central axis of a cone, and a through hole (7) of the flue dust sampling gun is arranged in the middle of the conic plug body (3) along the central axis direction of the cone; and the hole becomes from big to small from top to bottom, and a plurality of annular grooves (8) which are parallel to each other and are parallel to the upper surface and the lower surface of the conic plug body (3) are arranged on the inner wall of the plug body (3) in the through hole (7); the internal diameter D (14) of the groove closest to the upper surface of the conic plug body (3) is equal to the external diameter of the sampling gun (1), and the internal diameter E (15) of the groove closest to the lower surface of the conic plug body (3) is 5mm smaller than the external diameter of the sampling gun (1). The invention has simple and convenient disassembly and assembly, and is suitable for flue sampling holes with different aperture sizes.
Description
Technical field
The present invention relates to a kind of cock body, particularly a kind of hole plug that when smoke dust sampling, the thieff hatch of smoke dust sampling gun is stopped up.
Background technology
Smoke dust sampling gun is the important sample devices in boiler smoke, the fume emission test, in the test of boiler smoke, fume emission because the flue sampled aperture is in different size, make between sampling rifle and the flue and be easy to produce the gap, cause and leak out, had influence on the accuracy of sampling, the accident of burn testing crew has also taken place easily; Simultaneously and since when sampling smoke dust sampling gun closely cooperate with flue thieff hatch non-and environmental baseline is limit, need the testing crew scene to control the sampling rifle, increased the labour intensity of testing crew.
Summary of the invention
Smoke dust sampling gun and flue thieff hatch can not closely cooperate when a kind of hole plug for smoke sampling gun provided by the invention had solved sampling, make sampling unstable, inaccurate, and need operating personnel to control the technical matters that the sampling rifle burns the accident of scalding easily for a long time.
The present invention overcomes the above problems by following scheme:
A kind of hole plug for smoke sampling gun, comprise conical cock body 3, cock body connecting band 6 and cock body connecting band gib screw 11, described conical cock body 3 is divided into two lobe separate components by the vertical plane by this circular cone central shaft, the i.e. first lobe cock body 9 and the second lobe cock body 10, be provided with smoke dust sampling gun by hole 7 at described conical cock body 3 middle parts along the circular cone central axial direction, and aperture that should be by hole 7 along the circular cone central axial direction from top to bottom from large to small, this inwall by the cock body in the hole in hole 73 be provided with a plurality of that be parallel to each other and with conical cock body 3 on, the circular groove 8 that lower surface is parallel, and the inside diameter D 14 of the groove of the upper surface of the most close conical cock body 3 equates that with the external diameter of smoke dust sampling gun 1 the internal diameter E15 of the groove of the lower surface of the most close conical cock body 3 is littler 5 millimeters than the external diameter of smoke dust sampling gun 1; One end of described cock body connecting band 6 is fixed on the upper surface of the first lobe cock body 9 by cock body connecting band gib screw 11, and the other end of cock body connecting band 6 is fixed on the upper surface of the second lobe cock body 10 by cock body connecting band gib screw 11.
The vertical segmentation face that the vertical segmentation face of the second lobe cock body 10 is provided with triangle positioning key 12, the first lobe cock bodys 9 is provided with triangle locating slot 13.
Described smoke dust sampling gun 1 is provided with locating ring 2, and this locating ring 2 is located sampling rifle 1 with the groove fit of the upper surface of the most close described conical cock body 3.
The concave surface of described circular groove 8 is the concave surface of circular shape.
Hole plug for smoke sampling gun provided by the invention is accurately located smoke dust sampling gun when sampling, improved the accuracy of sampling, eliminated simultaneously because thieff hatch leaks out and causes the potential safety hazard of burn and scald testing crew, dismounting is simple and convenient, the different flue thieff hatch of applicable pore size.
