The invention relates to a gas sampling pipe used in a nitrogen reflow oven. The sampling pipe comprises a pipe body, a sampling pipe accessory and a sampling pipe support, wherein the pipe body has a cylindrical structure; the sampling pipe accessory is arranged on the pipe body; and the sampling pipe support is arranged in the middle of the pipe body, has a frame structure and is sleeved on the pipe body. Compared with the prior art, the gas sampling pipe has a high sealing property and a simple structure, and the cost can be saved; and in addition, parts adopted have high temperature resistance and heat dissipation property, so that the gas sampling pipe can be used at high temperature.
Description
Technical field
The present invention relates to a kind of gas sample tube, especially relate to a kind of gas sample tube that in the nitrogen reflux brazier, uses.
Background technology
The nitrogen reflux brazier all can be equipped with gas sample tube in the recirculating zone, with oxygen PPM level in the monitoring burner hearth.Used gas sample tube need be used manifold and connector at present, and on the one hand, the junction sealing of manifold and connector is poor, thereby influences the PPM value of oxygen in the burner hearth, with the quality that directly influences the nitrogen reflux brazier.On the other hand, manifold is to be processed by the 60mm square steel, and manufacturing cost is high, and heat dispersion is poor, and processing difficulties is unfavorable for a large amount of productions.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of good airproof performance, simple in structure, the resistant to elevated temperatures gas sample tube that in the nitrogen reflux brazier, uses to be provided.
The object of the invention can be realized through following technical scheme:
A kind of gas sample tube that in the nitrogen reflux brazier, uses; It is characterized in that; This sampling pipe comprises body, sampling pipe annex and sampling pipe support, and described body is a cylindrical-shaped structure, and described sampling pipe annex is located on the body; Described sampling pipe support is the shaped as frame structure, is set in the middle part of body.
Described sampling pipe annex comprises gland bonnet, sampling pipe chuck, O-ring seal, sampling pipe breakout box, sampling pipe joint and coupling bend; Described gland bonnet is set in the junction of body and sampling pipe chuck; Be provided with O-ring seal between gland bonnet and the body; The rear end of described sampling pipe chuck is folded on the gland bonnet, and front end is folded on the body, and described sampling pipe joint, coupling bend and sampling pipe breakout box are connected to the rear portion of body in turn.
Described sampling pipe annex comprises M4 socket head cap screw, M4 plain washer and M16 set nut, and described M4 socket head cap screw has two, jointly the sampling pipe support is fixed on the body with the M4 plain washer, and described M16 set nut is set in the front portion of body.
Described sampling pipe support is a closed-in construction, and the centre offers rectangular through-hole, and both sides are provided with the strip through hole, and body is through the gland bonnet sealing and after the sampling pipe chuck clamps, be located in the rectangular through-hole strip through hole internal fixation M4 socket head cap screw and M4 plain washer.
Compared with prior art, the present invention has the following advantages:
(1) good airproof performance: this gas sample tube adopts gland bonnet and O-ring seal that the sampling pipe chuck is connected with the sampling pipe joint, and sampling pipe and BOT PLD (Bottom Part Location Drawing) joint are coated with RTV (silica gel), good seal performance;
(2) simple in structure: these gas sample tube parts all adopt simple machined piece, and are simple in structure, easy to operate;
(3) save cost: effective coupling bend of this gas sampling and sampling pipe converter substitute manifold, replace the square steel workpiece with simple machined piece, provide cost savings, and are convenient to a large amount of productions;
(4) high temperature resistant: the parts that the present invention adopts have higher temperature tolerance and thermal diffusivity, and this gas sample tube can be used under high-temperature condition.
