Description
Technical field
The utility model relates to use armoured thermocouple test vacuum drying oven furnace temperature, and the Sealing Technology that armoured thermocouple is drawn from vacuum drying oven specifically, relates to a kind of vacuum drying oven and uses the external packoff of armoured thermocouple.
Background technology
With armoured thermocouple test vacuum drying oven furnace temperature, the armoured thermocouple electrical signal transmission line must be drawn from vacuum drying oven, drawing of armoured thermocouple, prior art are generally adopted the method shown in attached Fig. 1 and 2, and promptly armoured thermocouple is drawn body of heater by being installed on the copper contact rod on the vacuum drying oven ring flange.The copper contact rod passes ring flange, two ends are stretched out and are suspended from outside the ring flange, by with the copper contact rod on the nut that is complementary of screw thread, also tightly be installed on the ring flange copper contact rod from the ring flange two sides, the armoured thermocouple electrical signal transmission line is by two nuts and be close to and be connected to the copper contact rod and be positioned on the termination of ring flange both sides, and ring flange is fixedly mounted on the fire door of vacuum drying oven.The device that the armoured thermocouple of prior art is drawn from vacuum drying oven, the place of its deficiency, the one, the replacing installation and maintenance of every armoured thermocouple all will be dismantled ring flange, it is big to change the installation and maintenance workload, and the replacing of armoured thermocouple is installed, not only the sealing problem that exists between copper contact rod and the ring flange needs to solve, and the sealing problem between ring flange and the vacuum drying oven is more outstanding, and also more bad solution.The 2nd, armoured thermocouple can not directly be drawn body of heater, but draws body of heater indirectly by the copper contact rod, therefore can influence the accuracy of armoured thermocouple thermometric.The external packoff of the armoured thermocouple of prior art is difficult to satisfy those to the tight especially vacuum drying oven of temperature control requirement, and production practices need be developed the more perfect armoured thermocouple lead-out process of technology that makes new advances.
The utility model content
Deficiency at the external lead-out process existence of the armoured thermocouple of prior art, the vacuum drying oven that the purpose of this utility model aims to provide a kind of new construction uses the external packoff of armoured thermocouple, the armoured thermocouple replacing installation and maintenance workload that exists with the external packoff that solves prior art is big, problems such as sealing problem is many, and the thermometric accuracy is low.
The vacuum drying oven that the utility model proposes uses the external packoff of armoured thermocouple, mainly by armoured thermocouple being drawn hermetically the outer sealing adaptor of stove, ring flange that sealing adaptor is mounted thereon and device cylindrical shell constitute, the one end design of device cylindrical shell has the structure with vacuum drying oven fire door sealed attachment, the other end connects with flangeseal, sealing adaptor is installed on the ring flange removably, and armoured thermocouple passes from the containment member of sealing adaptor and draws outside the stove.
In technique scheme, described device cylindrical shell can be the conic tube that is provided with one section straight tube, and the design of straight tube end has the structure with vacuum drying oven fire door sealed attachment, and the conic tube end connects with flangeseal.The device cylindrical shell also can be designed to other versions, and as fewer when employed armoured thermocouple, the ring flange that sealing adaptor is installed is smaller, and the furnace port diameter of vacuum drying oven is when bigger, and the device cylindrical shell can be designed to straight barrel.
In technique scheme, described sealing adaptor preferentially adopts screw thread pair to be connected with ring flange, and promptly sealing adaptor is installed on the ring flange by the threaded hole on its extracorporeal thread and the ring flange.Can certainly take on other the mode mounting flange.
In technique scheme, the following version of the preferential employing of described sealing adaptor, form by a body, elastic material seal, top-pressure part and the gland that is provided with internal thread, the member central design of forming sealing adaptor has the through hole that therefrom passes for armoured thermocouple, the external thread that is complementary with ring flange threaded hole and gland internal thread is designed at body two ends respectively, has for seal and top-pressure part with design in the termination body of gland coupling to be installed on pore chamber in it.
In technique scheme, be installed on pore chamber in it for seal and top-pressure part, its degree of depth needs the height greater than seal, and the height that overlaps less than seal and top-pressure part.The reach of gland overlaps greater than seal and top-pressure part and exceeds the height that it installs the pore chamber part; The pore chamber that supplies seal and top-pressure part to be installed in it preferentially adopts cylindrical hole; The shape of seal and top-pressure part preferentially adopts right cylinder; Body is installed on ring flange threaded hole threaded one end afterbody and can designs spacing shoulder; Seal preferentially adopts the sealing column of teflon material.
The disclosed vacuum drying oven of the utility model uses the external packoff of armoured thermocouple, compare with the external packoff of prior art, because the ingenious structural design of sealing adaptor, make armoured thermocouple that change and repair are installed and do not need the dismounting ring flange, do not touch the sealing between vacuum drying oven and the ring flange, seal very reliably, solved the sealing problem that the armouring galvanic couple ejector of prior art exists fully, and used very convenient.In addition, because armoured thermocouple is directly drawn from vacuum drying oven, avoided the prior art armoured thermocouple to draw the existing signal transmission of vacuum drying oven indirectly and connected loss by the copper contact rod, therefore armoured thermocouple thermometric accuracy is improved, can satisfy various vacuum drying oven temperature precise control requirements, make the contribution of oneself for the progress that advances the armoured thermocouple lead-out process.
