Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
In description of the present utility model, except as otherwise noted, term " on ", the orientation of the instruction such as D score, "left", "right" or state relation be based on orientation shown in the drawings or state relation, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " crimping ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be directly be connected, also indirectly can be connected by intermediary.For the ordinary skill in the art, concrete condition the concrete meaning of above-mentioned term in the utility model can be understood.
A kind of lead sealing equipment of the present embodiment, it is the sealing of the lead-in wire (shielded thermocouple wire) of application and pressurized container, this device can be arranged on end cap (opening of the pressurized container) place of pressurized container, also can be the tapping be arranged on the sidewall of pressurized container, by integrated a branch of for many measurement lead-in wires, pass from areole, the device of the present embodiment be the areole of pressurized container and lead-in wire are restrainted between sealing, particular by what realize with under type:
As shown in Figure 1, a kind of lead sealing equipment of the present embodiment, comprises tightening nut 4 and the fixed base 1 being inserted in areole 7; Fixed base 1 is provided with the Seal cage 6 running through its body, for make lead-in wire 3 through and hold the high temperature colloid of sealing, colloid in Seal cage 6 after cooled and solidified, the sealing between shape paired lead 3 and Seal cage 6; The top of the sidewall of fixed base 1 is provided with outside thread, for being connected with tightening nut 4 screw-thread fit; The bottom of the sidewall of fixed base 1 is provided with annular boss 5, for coordinating with tightening nut 4 both sides clamping areole 7, in addition can also the first gasket seal 8 be set between annular boss 5 and areole 7, second gasket seal 9 is set between tightening nut 4 and areole 7, form the sealing between fixed base 1 and areole 7 thus, thus on the whole, make to be formed between areole 7 and lead-in wire 3 to seal.
Can also be filled with a sealing filler between lead-in wire 3 and the sidewall of Seal cage 6, and specifically can fill packing, packing forms fiber connecting tendon in colloid, strengthens the strength and stability of colloid.
This device also comprises fairlead 2 in addition, and fairlead 2 is inserted by the top of Seal cage 6, and is sheathed on lead-in wire 3, the bottom of Seal cage 6 is set to funnel shape, the sidewall of sealing cover is provided with outside thread, and the inwall of Seal cage 6 is provided with internal thread, and fairlead 2 is connected with Seal cage 6 screw-thread fit.Rotation ear can also be set on the top of fairlead 2, increase the arm of force rotated, rotation is more prone to, or the top of fairlead 2 is set to polygon-prism, rotate by utensils such as spanners, increase moment of torsion.Fairlead 2 is in the process screwing in Seal cage 6, packing is pressed into the bottom of Seal cage 6, bottom due to Seal cage 6 is funnel shape, packing is gradually compressed in the bottom of Seal cage 6, packing is being expanded to both sides by the process compressed, itself and the relative pressure between Seal cage 6 and fairlead 2 are increased, then coordinates the colloid be mixed into, sealing effect is promoted greatly.
If this device is arranged on the end caps of pressurized container, the opening of end cap is generally square, and the external frame in the stage casing of the fixed base 1 of this device is also set to square, make it to adapt with the opening shape of end cap, when tightening nut 4 is in fastening process, fixed base 1 and areole 7 form circumferential spacing pair, fixed base 1 is not together rotated with tightening nut 4, facilitates fastening; For the tapping that this device is arranged on pressurized container, the hole shape of pressurized container is set to adapt with the sectional shape of fixed base 1 sidewall, and the sectional shape of fixed base 1 sidewall is set to non-circular, in like manner, can make between the areole 7 of pressurized container and fixed base 1, to form circumferential spacing pair.
Operating process:
Sheathed first gasket seal on fixed base, makes the top of fixed base pass from the inside of the areole of pressurized container, then by integrated a branch of for many lead-in wires, passes from the Seal cage of fixed base.Packing is filled in Seal cage, and inject high temperature colloid, fairlead is inserted in Seal cage, and tightened gradually by the screw-thread fit of itself and Seal cage, packing presses down by the bottom of fairlead, and packing presses close to sidewall after being compressed, funnel shape place particularly bottom Seal cage forms pressing more closely, fairlead keeps the pressed status to packing under screw-thread fit, thus after colloid solidification, forms good sealing between lead-in wire and Seal cage.
Second gasket seal is set on fixed base, again by the top of tightening nut screw-thread fit in fixed base, tightening nut is in the process tightened, annular boss bottom fixed base and tightening nut are respectively by the both sides pressing of the first gasket seal and the second gasket seal and areole, in addition owing to there is circumferential spacing pair between the middle part of fixed base and areole, fixed base together can not be rotated with tightening nut, facilitate the fastening of nut.After tightening nut tightens, form sealing between fixed base and areole, thus realize the sealing between areole and wire by this device.
After being arranged on the pressurized container internal sensor sensor that is connected of insertion end of lead-in wire (namely with) and measuring, need to debug the inside of pressurized container according to metrical information, then again measure, so repeatedly.In this process, need this device of being dismounted for multiple times, and this device is when dismounting, only need carries out dismounting to tightening nut, lead-in wire and fairlead and fixed base integral demounting, make whole sealing and unloading process conveniently, time saving and energy saving.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
