Abstract
A kind of flared tube conical surface sealing structure, comprises port and is processed with the flared tube of outside enlarging and is connected to the conical surface seal body of flared tube port; The conical surface place that conical surface seal body contacts with flared tube port is provided with the upper conical surface and the lower conical surface, the upper conical surface and horizontal plane be angularly less than the lower conical surface and horizontal plane angularly and the angle that the upper and lower conical surface and horizontal plane are is less than the flaring angle of described flared tube simultaneously; Seal groove is provided with between the upper and lower conical surface, seal groove is built-in with sealing ring, the openend of seal groove is connected with upper and lower conical surface one respectively, and the open end of the seal groove be connected with upper conical surface one is provided with protruding corner angle, and the top edge of protruding corner angle overlaps with the upper conical surface of conical surface seal body.The utility model structure is simple, by presenting two kinds of angles at the sealing cone of conical surface seal body, make fastening rear flared tube inwall produce deformation under the effect of protruding corner angle, while sealing, reach the effect strengthening body pull-out force, improve the deficiencies in the prior art.
Description
Technical field
The utility model relates to the hermetically-sealed construction of flared tube end, especially a kind of flared tube conical surface sealing structure.
Background technology
Conical surface seal is the seal style that flared tube is conventional, when carrying out Butt sealing to two sections of flared tubes, need to be linked together between the port of two sections of flared tubes by conical surface seal body, device such as recycling flange and bolt fastener etc. is fastening by it, thus reaches the object of sealing.The sealing cone of the conical surface seal body used in current standard is same angle of inclination, utilize the sealing conical surface directly to seal or open on sealing cone O shape groove O shape circle single seal form.When this single seal failure, overall connection will be lost efficacy.And under bad working environments (if any the occasion required such as fire-resistant, corrosion-resistant), the probability occurring to lose efficacy can increase greatly.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, the sealing ensured under bad working environments, can promote the flared tube conical surface sealing structure connecting rear flared tube entirety pull-out force simultaneously.
The utility model solves the technical scheme that prior art problem adopts: a kind of flared tube conical surface sealing structure, comprises port and be processed with the flared tube of outside enlarging and be connected to the conical surface seal body of flared tube port; The conical surface place that described conical surface seal body contacts with flared tube port is provided with the upper conical surface and the lower conical surface, the described upper conical surface and horizontal plane be angularly less than the described lower conical surface and horizontal plane angularly and the angle that the upper and lower conical surface and horizontal plane are is less than the flaring angle of described flared tube simultaneously; Seal groove is provided with between the upper and lower conical surface, seal groove is built-in with sealing ring, the openend of described seal groove is connected with upper and lower conical surface one respectively, the open end of the seal groove be connected with described upper conical surface one is provided with protruding corner angle, and the top edge of described protruding corner angle overlaps with the upper conical surface of described conical surface seal body.
When flaring angle is 37 degree, the described upper conical surface and horizontal plane are angularly 35 degree, and the lower conical surface and horizontal plane are angularly 36 degree.
The beneficial effects of the utility model are: the utility model structure is simple, by arranging the upper conical surface horizontal by different angles and the lower conical surface on the sealing cone of conical surface seal body, the conical surface of seal is made to present two kinds of angles, and by the seal groove adjacent with the upper conical surface arranges protruding corner angle, make fastening rear flared tube inwall produce deformation under the effect of protruding corner angle, thus while effective sealing, reach the effect strengthening and connect rear body pull-out force; Seal groove is built-in with sealing ring simultaneously, has followed effect of sealing ring in prior art, thus improves the deficiency only utilizing the single seal form of the metal conical surface of conical surface seal body or O shape circle to produce in prior art.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described:
Fig. 2 is the enlarged drawing of the sealing cone of a kind of flared tube conical surface sealing structure of the utility model.A kind of flared tube conical surface sealing structure, comprises port and is processed with the flared tube 1 of outside enlarging and is connected to the conical surface seal body 2 of flared tube 1 port; The conical surface place that conical surface seal body 2 contacts with flared tube 1 port is provided with the upper conical surface 4 and the lower conical surface 3, the upper conical surface 4 and horizontal plane be angularly less than the lower conical surface 3 and horizontal plane angularly and the angle that the upper and lower conical surface 4,3 and horizontal plane are is less than the flaring angle of flared tube simultaneously, when flaring angle is 37 degree, preferably the upper conical surface 4 is angularly 35 degree with horizontal plane, and the lower conical surface 3 is angularly 36 degree with horizontal plane; Seal groove 5 is provided with between the upper and lower conical surface 4,3, seal groove 5 is built-in with sealing ring 7, the openend of seal groove 5 is connected with the upper and lower conical surface 4,3 one respectively, the open end of the seal groove 5 be connected with the upper conical surface 4 one is provided with protruding corner angle 6, and the top edge of protruding corner angle 6 overlaps with the upper conical surface 4 of conical surface seal body 2.Under normal circumstances, seal groove 5 can be processed into 0 shape groove, and sealing ring 7 can adopt O-ring seals.
Fig. 3 shows the utility model enlarged drawing at A place in Fig. 1 after tightening, as shown in Figure 3, sealing principle of the present utility model for: when the structure shown in Fig. 2 is by after the flange 8 of flared tube 1 outside is fastening (as shown in Figure 1), the change of Fig. 3 will be there is in sealing cone, namely constantly close along with flared tube 1 and conical surface seal body 2, the upper conical surface 4 of flaring angle and the lower conical surface 3 is all less than with horizontal plane angle due to the sealing cone of conical surface seal body 2 existing two, the inwall of press-in flared tube 1 port of the protruding corner angle 6 meeting high degree on therefore adjacent with the upper conical surface 4 seal groove 5, thus make the sealing ring 7 in seal groove 5 that maximum deformation occur, the pull-out force that protruding corner angle 6 can increase body entirety simultaneously makes entirety more firm.And then flared tube 1 and conical surface seal body 2 are issued to the object of dual-seal in the double action of protruding corner angle 6 and sealing ring 7.Under such air-proof condition, no matter under which kind of bad working environments (if any the occasion required such as fire-resistant, corrosion-resistant), even if a kind of seal failure, another kind of sealing also can play sealing function.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
