Abstract
The utility model discloses a truck air pipe which comprises a pipe body (1) and connecting portions (2) arranged at two ends of the pipe body (1). A nut (3) is connected at the middle rear end of each connecting portion (2) in a threaded manner, a sealing sleeve (4) is fixedly mounted on an opening end of each connecting portion (2) in a sleeved manner, a left sealing face (4.1) and a right sealing face (4.2) whose outer diameters gradually decrease from the middle to two ends are formed on the outer surface of each sealing sleeve (4), and a sealing inner wall fitted with the corresponding right sealing face (4.2) is formed inside a wall at the right end of each nut (3). The connecting portions of the truck air pipe have the advantage of good sealing effect.
Description
Technical field
The utility model relates to truck tracheae technical field, is specifically a kind of truck tracheae.
Background technique
At present, the connector portions of comparatively common truck tracheae is generally provided with outside thread, and the connector portions of other pipe fittings that are connected with truck tracheae is also provided with outside thread, when the truck tracheae of the type is connected with above-mentioned other pipe fittings, generally by screw the mode of nut on outside thread, connect sealing.
Truck tracheae adopts the mode of nut screwing clamping to connect sealing, and in actual use, the sealing effect of this kind of sealing means is unsatisfactory, and phenomenon probably leaks air.
Model utility content
The technical problems to be solved in the utility model is that a kind of truck tracheae of joint good sealing effect is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: it comprises body and is located at the joint at body two ends, the middle rear end of described joint is bolted with nut, on the opening end of described joint, fixed cover is equipped with stuffing box gland, the outer surface of sealing cover forms left sealing surface and the right sealing surface that external diameter is reduced to two ends gradually by middle part, and the inside of the right-hand member end wall of described nut is molded into the sealing inwall fitting with right sealing surface.
Adopt after above structure, the utlity model has following advantage: the utility model is by the setting of stuffing box gland, and by the setting of left sealing surface and right sealing surface, in the process being connected with other pipe fittings at truck tracheae, in the situation that nut screwing clamping forms first sealing configuration, the inwall of right sealing surface and nut right-hand member end wall fits and forms second sealing configuration, certainly, the inwall of the joint of other pipe fittings that are connected with truck tracheae is also molded into and fits with left sealing surface and form the structure of sealing, truck tracheae is under the comprehensive function of the first sealing configuration and the second sealing configuration like this, significant sealing affection increases, effectively avoided the generation of leaking.
As improvement, described stuffing box gland is 2～3mm to the distance of the edge of opening of joint, and described fixedly suit refers to by being welded and fixed suit, and the distance that leaves 2～3mm is convenient to welding, and is welded to connect solid and reliable.
Accompanying drawing explanation
Fig. 1 is the first structural representation of the utility model truck tracheae.
Fig. 2 is the second structural representation of the utility model truck tracheae.
As shown in the figure: 1, body, 2, joint, 3, nut, 4, stuffing box gland, 4.1, left sealing surface, 4.2, right sealing surface.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, a kind of truck tracheae, it comprises body 1 and is located at the joint 2 at body 1 two ends.On described joint 2, be bolted with nut 3, on the opening end of described joint 2, fixed cover is equipped with stuffing box gland 4.The outer surface of sealing cover 4 forms left sealing surface 4.1 and the right sealing surface 4.2 that external diameter is reduced to two ends gradually by middle part.The inside of the right-hand member end wall of described nut 3 is molded into the sealing inwall fitting with right sealing surface 4.2.Wherein orientation, left and right is as the criterion with the orientation, left and right in Fig. 1, and left sealing surface 4.1 and right sealing surface 4.2 are conical surface in addition.
Described stuffing box gland 4 to the distance of the edge of opening of joint 2 is 2～3mm.Described fixedly suit refers to by being welded and fixed suit.
Truck tracheae of the present utility model is by arranging stuffing box gland 4, when truck tracheae is connected with other pipe fittings, certainly, known according to general knowledge, the inwall of the joint of other pipe fittings has also been molded into and has fitted with left sealing surface and form the structure of sealing, under the double sealing structure of nut and stuffing box gland, the sealing effect of the joint of this truck tracheae has obtained effective raising like this, has avoided the leakage of gas.
Claims (2)
1. a truck tracheae, it comprises body (1) and is located at the joint (2) at body (1) two ends, the middle rear end of described joint (2) is bolted with nut (3), it is characterized in that: on the opening end of described joint (2), fixed cover is equipped with stuffing box gland (4), the outer surface of sealing cover (4) forms left sealing surface (4.1) and the right sealing surface (4.2) that external diameter is reduced to two ends gradually by middle part, and the inside of the right-hand member end wall of described nut (3) is molded into the sealing inwall fitting with right sealing surface (4.2).
