Description

Tube plate mounting structure with good sealing performance and convenient replacement

Technical Field

The utility model relates to a heater technical field, concretely relates to tube sheet mounting structure that sealing performance is good and be convenient for change.

Background

The electric heater is a device which is used more in work and life, and electric heating devices such as an electric furnace, an electric iron, an electric heater, an electric oven and the like belong to the electric heating devices. The electrothermal tube still is working when electric heater heating temperature is high enough, or under the water tank lack of water condition, the condition of electrothermal tube dry combustion for a long time, like this, the electric energy is wasted, and can be because of malignant accidents such as high temperature that the dry combustion causes catches fire, so in case damage, only can electric heater can install the temperature tube and carry out real-time supervision to the temperature of electric heater inside, but present temperature tube is through riveting or welding on the flange, riveting connection mode sealing performance is poor, welding connection mode sealing performance is good but the temperature tube in case damage, just will change whole flange.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art's weak point, provide a tube sheet mounting structure that sealing performance is good and be convenient for change.

The utility model provides a technical scheme of above-mentioned problem does: a tube plate mounting structure with good sealing performance and convenient replacement comprises a flange plate, a detachable mounting assembly and a temperature measuring tube connected to the flange plate through the detachable mounting assembly, wherein the detachable mounting assembly comprises a first clamp, a second clamp and a locking bolt;

the first clamp and the second clamp comprise a conical section and a cylindrical section, a first conical hole matched with the conical section of the second clamp is formed in the inner end of the locking bolt through hole, and the clamping groove is matched with the conical section of the first clamp;

the first clamp and the second clamp are made of elastic materials, such as rubber;

the length of the threaded hole is smaller than that of the threaded section of the locking bolt.

The utility model discloses beneficial effect has:

the utility model provides a tube sheet mounting structure that sealing performance is good and be convenient for change, sealing performance between temperature tube and the ring flange is good, and locking bolt tightly supports when locking state, and first clamp tightly supports temperature tube and joint groove, and the second clamp tightly supports temperature tube and locking bolt, and locking bolt unscrews, can take out the temperature tube, has realized the demountable installation of temperature tube.

in the figure: the temperature measuring device comprises a flange plate 1, a temperature measuring pipe 2, a first clamp 3, a second clamp 4, a locking bolt 5, a mounting hole 6, a first hole groove 7, a clamping groove 8, a threaded hole 9 and a first conical hole 10.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

As shown in the figure, the tube plate mounting structure with good sealing performance and convenient replacement comprises a flange plate 1, a detachable mounting assembly and a temperature measuring tube 2 connected to the flange plate 1 through the detachable mounting assembly, wherein the detachable mounting assembly comprises a first clamp 3, a second clamp 4 and a locking bolt 5, the centers of the first clamp 3, the second clamp 4 and the locking bolt 5 are provided with through holes for the temperature measuring tube 2 to pass through, the flange plate 1 is provided with a mounting hole 6, the first clamp 3, the second clamp 4 and the locking bolt 5 are sequentially arranged in the mounting hole 6 from inside to outside, the mounting hole 6 comprises a first hole groove 7 from inside to outside, a clamping groove 8 for clamping the first clamp 3 is used for connecting a threaded hole 9 of the locking bolt 5 in a threaded manner, and the length of the threaded hole 9 is smaller than that of a threaded section of the locking bolt 5;

first clamp 3 and second clamp 4 are elastic material, such as rubber, first clamp 3, second clamp 4 include toper section and cylindricality section, locking bolt 5 fenestrate inner be equipped with the first bell mouth 10 of toper section complex of second clamp 4, joint groove 8 cooperates with the toper section of first clamp 3.

When the temperature measuring pipe 2 is installed, firstly, the locking bolt 5, the second hoop 4 and the first hoop 3 are sequentially sleeved on the temperature measuring pipe 2, the orientation of the locking bolt 5, the orientation of the second hoop 4 and the orientation of the first hoop 3 are noticed, the temperature measuring pipe 2 is inserted into the mounting hole 6, then the first hoop 3 and the second hoop 4 are pushed into the mounting hole 6, and the locking bolt 5 is locked in the threaded hole 9. Simple to operate, locking bolt 5 are bolted and are in when locking state, and first clamp 3 tightly supports temperature tube 2 and joint groove 8, and second clamp 4 tightly supports temperature tube 2 and locking bolt 5, and the sealing performance between temperature tube 2 and the ring flange 1 is good, and locking bolt 5 unscrews, can take out temperature tube 2.
