Description
Technical field
The utility model relates to a kind of nonmetallic flange disc, particularly a kind of flame-retardant and anti-static underground mine use pipeline nonmetallic flange disc.
Background technique
In pipeline connected, the use of flange plate was very extensive, and pipeline is metal material with flange plate under the coal mine at present.Though there is not the flame-retardant and anti-static problem in the metal flange dish, but geological environment inclement condition under the coal mine, as there was dampness in the air, there are inflammable and explosive dust and gas, various corrosive gas, liquid substance etc., pH value have up to 2～3, the metal flange dish easily is corroded, and causes that the length of service is short, maintenance cost is high.The metal flange dish that uses all passes through the application of spraying paint at present, and it is that a kind of very important anticorrosive metal keeps means.The good coating protection layer that sprays paint keeps continuous whole harmless, in conjunction with good, can become and suppress the barrier that aggressive medium is invaded.But because corrosion is irreversible spontaneous process; even the application of spraying paint of high-quality keeps layer; also be difficult to protect metal not corrode; especially spray paint the application layer in conjunction with bad when the metal surface; be damaged, or pin hole is arranged, bubbling, defective such as chap, come off; varnished protective action will descend greatly, even cause the disastrous effect of metal erosion aggravation.Therefore the application of spraying paint is limited to the prolongation in metal flange dish working life after all, still can not be complementary with the plastic pipe life-span; And the painting process complexity, also increased cost greatly.
Therefore need a kind of safe, high working efficiency, the low underground mine use of cost is in pipeline flange connecting dish.
The model utility content
In view of this, technical problem to be solved in the utility model provides a kind of safe, high working efficiency, and the low underground mine use of cost is in pipeline flange connecting dish.
The utility model is achieved through the following technical solutions:
The underground mine use pipeline nonmetallic flange disc that the utility model provides, include the center hole that disk body, mounting hole and disk body middle part are provided with, described mounting hole is along the circumferencial direction setting of disk body, also include horizontal stiffening rib, described horizontal stiffening rib replaces arranged type along the circumferencial direction of disk body and is arranged between the mounting hole.
Further, also comprise along disk body radially be arranged at the waling I between horizontal stiffening rib and the center hole and/or be arranged at mounting hole and center hole between waling II.
Further, also comprise the interior ring stiffening rib that is arranged on the center hole edge;
Further, also comprise and be arranged on the outer peripheral outer shroud stiffening rib of disk body;
Further, also be provided with the groove of alternately arranging along the circumferencial direction of disk body on the described disk body;
Further, described flange plate disk body is for adopting the nonmetallic flange disc of modified polyphenylene sulfide resin through disposable compression molding or the moulding of secondary thermoforming process.
The beneficial effects of the utility model are: the utility model adopts and is provided with the flange plate that replaces the stiffening rib of arranging along the circumferencial direction of disk body, can add powerful conduction on the one hand, reduce shear deformation, can increase the flange plate rigidity on the other hand, the groove that flange plate is alternately arranged along the circumferencial direction of disk body can weight reduction, and flange plate adopts modified polyphenylene sulfide resin through disposable compression molding or the moulding of secondary thermoforming process, has corrosion-resistant, long service life (doubly) than the long 2-3 of metal flange dish, bump does not produce spark, machine shaping is convenient, low pipeline and the joint of not damaging of hardness, the specific strength advantages of higher.Have permanent fire-retardant, anti-static electricity property simultaneously, realize that the colliery to mould Dai Gang, has the life length identical with plastic pipe, this again for the colliery has reduced cost, satisfies the needs of colliery high-efficiency mining and safety in production virtually.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by following specification and claims.
Description of drawings
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is a underground mine use pipeline nonmetallic flange disc structural representation.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.
Fig. 1 is a underground mine use pipeline nonmetallic flange disc structural representation; As shown in the figure: the underground mine use pipeline nonmetallic flange disc that provides of the present utility model, include the center hole 3 that disk body 1, mounting hole 2 and disk body middle part are provided with, described mounting hole 2 is along the circumferencial direction setting of disk body, also include horizontal stiffening rib 4, described horizontal stiffening rib 4 replaces arranged type along the circumferencial direction of disk body and is arranged between the mounting hole 2, increased the rigidity of disk body, improved working life at horizontal direction.
Further improvement as the foregoing description, also comprise along disk body 1 radially be arranged at the waling I5 of the setting between horizontal stiffening rib 4 and the center hole 3 and/or be arranged at mounting hole and center hole between the waling II6 of setting, increased the rigidity of disk body, improved working life at longitudinal direction.
