Abstract
The utility model discloses a double-sealing spherical compensation connector, which comprises a body and a spherical casing. One section of a spherical casing inner cavity is spherical, and one section of spherical surface matched with the spherical casing is arranged on the body. The spherical surface of the body is arranged in the spherical casing inner cavity, and one end of the spherical casing extends outwards to form a joint portion. The joint portion and the spherical casing inner wall form a step, and the end surface of the joint portion is connected with a gland through a connection bolt and a connection nut. An inner cavity of the gland is matched with the spherical casing inner cavity in shape to form a spherical inner cavity. A U-shaped seal ring is arranged between the end surface of the gland and the spherical casing step. In addition, a spherical rubber pipe is further arranged in the spherical inner cavity formed by the body and the spherical casing, and flanges are arranged at two outward ends of the spherical casing and the body respectively. The double-sealing spherical compensation connector is simple in structure, good in deflection and sealing effect and high in safety reliability.
Description
Technical field
The utility model relates to a kind of pipe coupling, and is particularly related to a kind of spherical compensating joint of double-sealing of good sealing effect.
Background technique
At present; Various pipe-line systems are for example: gas pipe line; Water supply line, oil transport pipelines etc. are applied in the daily life widely, but in the process of deployment of various pipe-line systems, often to consider because surface subsidence is serious, vibrations are big, with a varied topography and seasonal variations and day and night big pipeline deflection that produces of the temperature difference and expand with heat and contract with cold etc. all can pipeline be produced serious influence; General solution is that axial displacement and the deflection angle off-centre that compensating joint remedies pipeline is set in the process of deployment of pipeline; Spherical compensating joint is a kind of joint with large deflection, and it can free deflection in 30 ° scope, with remedy because of foundation settlement serious; And external force effect and the pipeline deflection that produces and pipeline turn round etc. under the situation; The problem that possibly occur, therefore high to its sealing and reliability requirement, the traditional shortcoming that pipe coupling ubiquity sealing effect is bad and safety reliability is not high.
The model utility content
The purpose of the utility model is to provide a kind of double-sealing spherical compensating joint, and it has simple in structure, and good sealing effect has the high characteristics of good amount of deflection and safety reliability.
The purpose of the utility model is to realize through following technological scheme:
The spherical compensating joint of a kind of double-sealing; It comprises body and spherical shell; Wherein, a section of said spherical shell inner chamber is spherical in shape, the sphere to there being a section to cooperate with spherical shell on body; Said body cooperatively interacts through link with spherical shell and is connected, and also is provided with the spherical rubber pipe in the spherical inner chamber of said body and spherical shell formation.
Said body sphere is arranged at the spherical shell inner chamber; And an end of said spherical shell is outward extended with the joining portion; Said joining portion and spherical shell inwall form a step; The end face at said joining portion is connected gland through connecting bolt with the attaching nut, and the cavity shape of said gland cooperates the spherical shell inner chamber to constitute a spherical inner chamber together, and between the end face of said gland and the spherical shell step U RunddichtringO is set.
The outside two ends of said spherical shell and body are provided with flange.
The beneficial effect of the utility model is that the body and the spherical shell of the spherical compensating joint of said double-sealing utilize sphere to cooperatively interact, and have both guaranteed that connecting head has enough rigidity; Make again between body and the spherical shell and can relatively move, guarantee certain amount of deflection, utilize gland extruding U RunddichtringO; Reach the effect of sealing and deflection, and in the spherical inner chamber of body and spherical shell formation, also be provided with the spherical rubber pipe, have the double seal effect; Not only simple in structure, have good amount of deflection; And good sealing effect, safety reliability is high.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the spherical compensating joint of the utility model double-sealing.
Among the figure:
1, spherical shell; 2, body; 3, body sphere; 4, joining portion; 5, spherical shell step; 6, gland; 7, seal ring; 8, connecting bolt; 9, attaching nut; 10, spherical rubber pipe.
Embodiment
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of the spherical compensating joint of the utility model double-sealing, in present embodiment; The spherical compensating joint of a kind of double-sealing, it comprises body 2 and spherical shell 1, a section of said spherical shell 1 inner chamber is spherical in shape; Body sphere 3 to there being one section to cooperate on body 2 with spherical shell 1, said body sphere 3 is arranged at spherical shell 1 inner chamber, and an end of said spherical shell 1 is outward extended with joining portion 4; Said joining portion 4 forms a spherical shell step 5 with spherical shell 1 inwall; The end face at said joining portion 4 is connected gland 6 through connecting bolt 8 with attaching nut 9, and the cavity shape of said gland 6 cooperates spherical shell 1 inner chamber to constitute a spherical inner chamber together, and between the end face of said gland 6 and the spherical shell step 5 U RunddichtringO 7 is set; In addition; Also be provided with spherical rubber pipe 10 in the spherical inner chamber of said body 2 and spherical shell 1 formation, the outside two ends of said spherical shell 1 and body 2 are provided with flange, through the flange connections road.
The body 2 of the spherical compensating joint of above-mentioned double-sealing utilizes sphere to cooperatively interact with spherical shell 1, has both guaranteed that connecting head has enough rigidity, makes again between body 2 and the spherical shell 1 and can relatively move; Guarantee certain amount of deflection, tighten connecting bolt 8, utilize gland 6 extruding U RunddichtringOs 7; Make U RunddichtringO 7 produce deformation, hoop tightly reaches the effect of sealing and deflection on pipeline; And in the spherical inner chamber that body 2 and spherical shell 1 form, also be provided with spherical rubber pipe 10; Make connecting head have the double seal effect, not only simple in structure, have good amount of deflection; And good sealing effect, safety reliability is high.
