The technical problems to be solved in the utility model be overcome prior art exist deficiency, provide a kind of simple and compact for structure, sealing reliability is high, the black box of easy accessibility.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of black box, comprise sealing channel and be installed in the seal plug in described sealing channel, the limit assembly for preventing described seal plug from deviating from is equiped with in described sealing channel, described limit position part comprises stop member and is located at the draw-in groove on the inwall of described sealing channel, and described stop member is dismountable to be arranged in described draw-in groove and to offset with described seal plug.
As further improvement of the utility model:
Described draw-in groove is annular groove, the elastic spring that described stop member is, described elastic spring curls up in the shape of a spiral and forms two or more reed circle and be arranged in described annular groove.
Described elastic spring is provided with the pulling portion of the outside of extending draw-in groove away from one end of seal plug.
The joint of adjacent two reed circles is provided with kink, and two connecting ends that described kink is connected with described adjacent two reed circles equal the thickness of described elastic spring curling up the spacing on axial direction.
Described seal plug comprises plug body, and described plug body offers installation annular groove, and described installation annular groove is in-built is provided with seal ring.
One end of described plug body is provided with end cap, and described end cap and described stop member offset.
Described sealing channel is the tube chamber of pipeline or the cylinder chamber of cylindrical shell.
Compared with prior art, the utility model has the advantage of: the seal plug of the utility model black box and limit assembly are all installed in sealing channel, offset with seal plug in the draw-in groove that the stop member of limit assembly is dismountable to be arranged on sealing channel inwall, the stop position-limiting action that stop member is formed seal plug, can effectively prevent seal plug from deviating from sealing channel, and stop member is convenient to disassembly, can greatly improve dismounting efficiency; Sealing assembly has the advantages such as simple and compact for structure, sealing reliability is high, easy accessibility is quick.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the utility model black box, comprise sealing channel 1 and be installed in the seal plug 2 in sealing channel 1, the cross section of sealing channel 1 is circular, it can be the tube chamber of pipeline or the cylinder chamber of cylindrical shell, be positioned at the import and export position of pipeline or cylindrical shell, thus sealing is formed to pipeline or cylindrical shell.Also limit assembly is equiped with in sealing channel 1, limit position part comprises stop member and is located at the draw-in groove 11 on the inwall of sealing channel 1, stop member is elastic spring 3, it can adopt steel wire sheet to make, elastic spring 3 elastic card to be located in draw-in groove 11 and to be offseted with seal plug 2, formed and stop position-limiting action, can effectively prevent seal plug 2 under sealing load, deviating from sealing channel 1.Because seal plug 2 and elastic spring 3 are all installed in sealing channel 1, black box is made to have simple and compact for structure, that sealing reliability is high advantage, elastic spring 3 adopts dismountable card to establish mounting type simultaneously, can also carry out dismounting easily and fast, can greatly improve dismounting efficiency.
In the present embodiment, draw-in groove 11 is annular groove, elastic spring 3 curls up in the shape of a spiral and forms two or more reed circle, the diameter of reed circle is greater than the internal diameter of sealing channel 1, because elastic spring 3 has resiliently deformable effect, elastic spring 3 can stretch along the direction of curling up axle, reed circle also can be made radially to be out of shape simultaneously, and such elastic spring 3 can load in draw-in groove 11 easily or split out in draw-in groove 11.During concrete installation, first seal plug 2 is loaded in sealing channel 1, one end of elastic spring 3 is made to insert in draw-in groove 11, rotating makes whole elastic spring 3 load draw-in groove 11 again, or make one end of elastic spring 3 insert in draw-in groove 11, make reed circle radial deformation be pressed into draw-in groove 11 piecemeal again, finally make whole elastic spring 3 load draw-in groove 11.Change the parameters such as the quantity of reed circle, material and thickness, the sealing intensity of different size can be met.
In the present embodiment, elastic spring 3 is provided with pulling portion 31 away from one end of seal plug 2, this pulling portion 31 extends the outside of draw-in groove 11, also namely extend in sealing channel 1, reed circle can be made radially to be out of shape by pullling pulling portion 31, and then elastic spring 3 is split out from draw-in groove 11, its convenient disassembly is quick.
In the present embodiment, the joint of adjacent two reed circles is provided with kink 32, two connecting ends that kink 32 is connected with adjacent two reed circles equal the thickness of elastic spring 3 curling up the spacing on axial direction, namely also adjacent two reed circles shift to install curling up on axial direction, and the spacing of adjacent two reed circles dislocation is the thickness of an elastic spring 3, after elastic spring 3 is compressed, the plane at each reed circle place all with curl up axes normal, and each reed circle is close to mutually, elastic spring 3 after compression is equivalent to both ends of the surface all perpendicular to the Cylindrical object curling up axis, such reed circle of elastic spring 3 one end and the surface of contact of seal plug 2 are the plane perpendicular to curling up axis, the surface of contact of the reed circle of elastic spring 3 the other end and the sidewall of draw-in groove 11 is also perpendicular to the plane of curling up axis, stressed uniformity and balance can be ensured, and then guarantee sealing effect.In addition, compared with the structure that elastic spring 3 and draw-in groove 11 coordinate adopts flange sealing structure with tradition, not needing to ensure stressed uniformity and balance by back and forth twisting screw, a large amount of disassembly and assembly times can be saved, its installation and removal efficiency improves greatly, and is more easy to ensure sealing effect.
In the present embodiment, seal plug 2 comprises plug body 21, spaced apartly vertically on plug body 21 is provided with two and installs annular grooves 22, and each installation in annular groove 22 is all equiped with seal ring 23, and plug body 21 loads after in sealing channel 1 and forms sealing in the form of piston.One end of plug body 21 is provided with the end cap 24 in cylinder boss shape, and end cap 24 and elastic spring 3 offset.
The seal plug 2 of the utility model black box, seal ring 23 and elastic spring 3 are manufactured easily, and cost of production is low, is beneficial to and applies.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment.For those skilled in the art, do not departing from the improvement that obtains under the utility model technical conceive prerequisite and conversion also should be considered as protection domain of the present utility model.
