Abstract

The utility model relates to the field of measurement using a corundum reaction tube in a laboratory, and in particular relates to a reaction tube port sealing device. The reaction tube port sealing device is characterized by comprising an air inlet side sealing end and an exhaust side sealing end, wherein the air inlet side sealing end comprises a metal end cover I, a rubber ring and a metal ring I, wherein the metal ring I is sheathed on the outer surface of the end of an air inlet side of the reaction tube and is provided with external thread, and a sealing ring is arranged between the metal end cover I and a reaction tube port in a connecting state; the exhaust side sealing end comprises a metal end cover II, another rubber ring and a metal ring II, wherein the metal ring II is sheathed on the inner surface of the end of an exhaust side of the reaction tube and is provided with internal thread; and another sealing ring is also arranged between the metal end cover II and another reaction tube port in a connecting state. Compared with the prior art, the reaction tube port sealing device has the beneficial effects that two metal sealing elements are adopted at the two ends of the reaction tube, so that the reliability of sealing can be guaranteed, and the operation of assembling and discharging a sample is more convenient and faster; and a thermocouple can be disassembled, thus a couple is conveniently replaced and cleaned.

Description

A kind of reaction pipe port sealing device

Technical field

The utility model relates to experimental determination with corundum qualitative response pipe field, relates in particular to a kind of reaction pipe port sealing device.

Background technique

,,, adopt conduit that gas in the reaction pipe is drawn and supply to analyze during at the experimental determination coal so will the two ends of corundum qualitative response pipe be sealed owing to will carry out collection analysis to the fugitive constituent gas that course of reaction produces to the carbon dioxide chemical reactivity.

The Sealing that adopts at present is rubber stopper or other soft ground materials, after corundum qualitative response pipe is heated because expand with heat and contract with cold, combined factors effects such as high temperature and the interior gas pressure of reaction pipe, rubber stopper is as easy as rolling off a log to get loose, and makes sample from reaction pipe, gush; Because the reactant fugitive constituent has corrosivity, it is rotten to make the rubber stopper use will harden soon, loses the effect of sealing; In addition, the air inlet side not only will import gas and also will insert thermocouple and carry out thermometric during reaction, because that thermocouple itself adopts the high temperature resistant porcelain tube of insulation to protect is frangible especially, so take on the sample careful operation of all being careful at every turn.

Above-mentioned link usually causes dress appearance to go out a kind operation failure, and these problems perplex industry always and can't be properly settled for a long time.

Summary of the invention

The purpose of the utility model provides a kind of reaction pipe port sealing device, overcomes the deficiency of existing technology, adopts metal seal at the reaction pipe two ends, guarantees sealing reliability, and it is quick to make dress appearance go out kind more convenient operation.

For solving the problems of the technologies described above, the technological scheme of the utility model is:

A kind of reaction pipe port sealing device; Comprise air inlet side sealing end and exhaust side sealed end; Said air inlet side sealing end comprises metal end one, seal ring and metal ring one; Metal ring one is enclosed within reaction pipe air inlet side end outer surface and is provided with outside thread, and metal end one and metal ring one are connected through screw thread, are provided with seal ring between metal end one and the reaction pipe port when being in coupled condition.

Also be provided with suction tude and thermocouple on the said metal end one tapped hole is installed, the suction tude end is provided with rapid pipe joint.

Said exhaust side sealed end comprises metal end two, seal ring and metal ring two; Metal ring two is enclosed within reaction pipe exhaust side end internal surface and is provided with internal thread; Metal end two and metal ring two are connected through screw thread, are provided with seal ring between metal end two and the reaction pipe port when being in coupled condition.

Also be provided with outlet pipe on the said metal end two, the outlet pipe end is provided with rapid pipe joint.

Compared with prior art; The beneficial effect of the utility model is: abandoned the sealing of traditional rubber stopper or nonmetal softwood matter class; Through adopting metal seal at the reaction pipe two ends, can guarantee the reliability that seals, it is quick to make dress appearance go out kind more convenient operation; Thermocouple is detachable, makes to change galvanic couple or clear up more convenient.
