The invention provides a pipeline connector capable of deflecting any angle, which comprises a front half body 1, a rear half body 5 and a sealing assembly.

After the front half body 1 and the rear half body 5 are connected, a deflection pipeline can be inserted. The connecting gap between the front half body 1 and the rear half body 5 is sealed through the sealing assembly, so that the connection tightness of the pipeline connector is realized.

The following invention mainly describes the deflectable arbitrary angle part of the pipe connector in detail, and outlines the other parts in simple structure.

The front half body 1 and the rear half body 5 both comprise two connected pipe sections, and the two pipe sections are respectively a cylindrical barrel and a spherical barrel.

The spherical cylinder 1d of the front half body 1 is covered on the spherical cylinder 5b of the rear half body 5 and is arranged concentrically, so that the spherical cylinders of the front half body and the rear half body can rotate around a common sphere center. By adopting the scheme and the structure of matching two spherical surfaces, when the inner spherical barrel and the outer spherical barrel are concentric, the inner spherical barrel can rotate freely in the outer spherical barrel.

The opening terminal surface outside of the globular barrel 1d of first half section body 1 sets up first flange 1b, and a plurality of bolt holes 1e of equipartition on the terminal surface of first flange 1b can be connected with external pipe fitting through bolt assembly.

The sealing assembly comprises a gland 4, a pressure ring 3 and a sealing ring 2 which are sequentially sleeved on a spherical barrel 5b of the rear half body 5, the gland 4 is of a flange ring structure, a plurality of bolt holes are formed in the flange end face of the gland 4 and the relative position of the first flange 1b, and the bolt holes 1e uniformly distributed in the bolt holes and the end face of the first flange 1b outside the socket end face are connected through bolt assemblies to play a role in connection and sealing. The press ring 3 and the seal ring 2 are interposed between the gland 4 and the first flange 1 b.

In particular, the axis of the opening end surface of the spherical cylinder 1d of the front half body 1 forms an included angle with the axis of the cylindrical cylinder 1 a. The opening end face of the spherical cylinder 1d of the first half body 1 is not parallel to the opening end face of the cylindrical cylinder 1a, but deflects by an angle, and the direction of the deflection angle is towards the direction close to the opening end face of the cylindrical cylinder 1 a.

Similarly, the axis of the opening end face of the spherical cylinder 5b of the rear half body 5 has an angle with the axis of the cylindrical cylinder thereof. The opening end face of the spherical cylinder 5b of the rear half body 5 is not parallel to the opening end face of the cylindrical cylinder, but deflects by an angle, and the direction of the deflection angle is towards the direction far away from the opening end face of the cylindrical cylinder.

As shown in fig. 2, since the spherical cylinder is disposed to be offset with respect to the cylindrical cylinder, it can be seen that the spherical cylinder 1d of the front half body 1 and the spherical cylinder 5b of the rear half body 5 are both long in one side wall and short in the other side wall.

The longer side walls of the spherical cylinder 1d of the front half body 1 and the spherical cylinder 5b of the rear half body 5 are overlapped, and the shorter side walls are overlapped, and the arrangement can enable the two spherical cylinder structures to be not limited when deflecting, so that the space is large enough and the deflection angle is maximized.

The deflection angle can include two aspects, namely, on the plane shown in fig. 2, the included angle of the axes of the two spherical cylinders can deflect within a certain range; on the other hand, one of the two spherical cylinders can be deflected about the axis of the other. The foundation for realizing the maximum deflection angle is the beveling design of the opening end surface of the spherical cylinder.

The inner spherical cylinder 5b of the rear half body 5 can be inserted into the outer spherical cylinder 1d of the front half body 1, and when the spherical centers of the two spherical cylinders are overlapped, the two spherical cylinders can rotate around the common spherical center. After the relative position of deflection between the front half body 1 and the rear half body 5 is adjusted, the bolt holes uniformly distributed on the end surfaces of the gland 4 and the first flange 1b are connected through the bolt assemblies, and the connecting and sealing effects are achieved. When the gland 4 is axially moved under the action of the bolt, the pressing ring 3 is respectively acted by axial force and radial force, the sealing ring 2 is compressed by the axial force, the pressing ring 3 is tightened by the radial force, and finally the function of sealing a connecting gap between the front half body 1 and the rear half body 5 is achieved.

The inner wall of the spherical cylinder 1d is a socket inner spherical surface 1 g. The opening end face of the spherical cylinder 1d is a socket end face 1h, and the socket end face 1h deflects at an angle toward the opening end face of the cylindrical cylinder 1 a.

The opening end face of the spherical cylinder 5b is a socket end face 5g, and the socket end face 5g is deflected at an angle toward the opening end face of the cylindrical cylinder 5 a.

Specifically, the open ends of the front half body 1 are provided with first flanges 1 b. The open end outside of the cylindrical barrel of half body 5 sets up second flange 5c, sets up a plurality of bolt holes 5d on second flange 5 c. A plurality of bolt holes are uniformly distributed on the end surfaces of the first flange 1b of the front half body 1 and the second flange 5c of the rear half body 5, and the bolt holes can be connected with an external connecting pipe through bolt components respectively.

In addition, the pipeline connector can also be matched with an anti-skid connector structure in the prior art, so that the anti-skid function can be increased. The cylindrical barrel opening end faces of the front half body 1 and the rear half body 5 are provided with flanges, and at the moment, the pipeline connector only keeps the sealing property.

The open end of the cylinder body of the front half body 1 and the rear half body 5 is provided with a sealing ring accommodating part. The inner ring surfaces of the sealing ring accommodating parts of the front half body 1 and the rear half body 5 are conical ring surfaces and are matched with the conical ring surfaces of the outer ring surfaces of the sealing rings, and when the sealing rings are acted by axial force, the sealing rings can shrink axially and radially to wrap the outer spherical surfaces of the pipeline and the socket to finish sealing.

In the specific embodiment, the opening end surface of the spherical cylinder 1d of the front half body 1 is a socket end surface 1h, and the socket end surface 1h has a seal ring accommodating portion 1f for accommodating the seal ring 2. The seal ring accommodating portion 1f is step-shaped, and the diameter of the inner ring thereof is larger than that of the socket end face 1 h.

Further, the outer annular surface of the seal ring 2 is a tapered annular surface, the axis of which is perpendicular to the socket end surface 1h, and the outer annular surface of the seal ring 2 and one end surface thereof are in contact with the seal ring accommodating part 1f expanded from the socket end surface 1 h. The inner ring surface of the sealing ring 2 is a spherical surface, and the inner spherical surface of the front half body 1 is attached to the outer spherical surface of the rear half body 5 of the socket.

The opening terminal surface outside all sets up first flange 1b about half preceding section body 1, and a plurality of bolt holes 1c of equipartition, 1e can be connected with external pipe fitting through bolt assembly on the terminal surface of first flange 1 b.

Similarly, the gland 4 is a flange ring structure, a plurality of bolt holes are uniformly distributed on the flange end face of the gland, and the bolt holes are connected with the bolt holes uniformly distributed on the end face of the first flange 1b outside the socket end face 1h through bolt assemblies to play a role in connection and sealing.

In a specific embodiment, the pressing ring 3 is a rubber pressing ring, and the sealing ring 2 is a rubber sealing ring. Furthermore, the rubber seal ring is compressed and deformed by the rubber compression ring and the gland 4 to play a role of sealing the socket and spigot, and is kept fixed by the locking function of the gland 4.

In the structure, when the gland 4 is axially moved under the action of the bolt, the rubber compression ring 3 is respectively acted by axial force and radial force, the rubber sealing ring is compressed by the axial force, and the rubber compression ring is tightened by the radial force to finally play a role in sealing and fixing the bell and spigot.

When the pressed cover 4 is locked, the rubber sealing ring 2 can be compressed on one hand, and can be radially contracted on the other hand, so that the friction force between the rubber sealing ring and the outer spherical surface of the inner spherical barrel is increased, and the anti-skidding effect is achieved.

It can be understood that the maximum deflectable angle of the pipe connector is the deflectable angle of the socket end face 1h and the socket end face 5g when the gland 4 interferes with the socket section, and the minimum deflectable angle of the pipe connector is zero, and at this time, the pipe connector is a normal straight pipe connection. When the deflection angles of the socket end face 1h and the socket end face 5g are zero, the existing market product technology is obtained.

In fact, when the deflection angles of the socket end face 1h and the socket end face 5g of the pipe connector are determined, the minimum deflection angle of the pipe connector occurs when the socket is about to be separated from the seal ring 2, and the maximum deflection angle of the pipe connector occurs when the gland 4 and the socket section are about to interfere with each other. During actual construction and installation, a proper deflection angle is selected for installation according to geological conditions and field conditions so as to prevent failure caused by influences of factors such as geological settlement and the like after installation.

The specific implementation steps are as follows:

firstly, a gland 4 is sleeved on a spherical cylinder (socket part) 5b of a rear half body 5, then a rubber pressure ring 3 and a rubber sealing ring 2 are sequentially sleeved on the spherical cylinder, then a front half body 1 is sleeved on the spherical cylinder, the rubber sealing ring 2 is pushed into a socket sealing ring accommodating part 1f, a proper deflection angle is adjusted, the gland 4 is locked with a first flange 1b through a bolt component, at the moment, two sections of pipelines are connected through the connector, and the pipeline connector can adapt to pipeline connection at any deflection angle due to deflection arrangement of a socket end surface 1h and a socket end surface 5g of the pipeline connector. In practical use, the proper deflection angle is adjusted to connect according to the site construction environment and geological conditions.

Due to the adoption of the technical scheme, the invention has the beneficial effects that: the pipeline connector capable of deflecting at any angle can adapt to connection of two pipelines when the two pipelines are not on the same axis, can be used when the deflection angle of the axes of the two pipelines is large, and can prevent failure caused by influences of factors such as geological settlement after installation.
