Abstract
The utility model discloses a joint for a three-jaw type corrugated pipe, which is used to connect two segments of corrugated pipes, and comprises a pipe clamp which is coated on the outer wall of an interface of the two corrugated pipes, wherein the pipe clamp comprises three segments of arc-shaped shells which have the same shape, the connection angle of the arc-shaped shells is 120 degrees, and soft sealing cushions are arranged between the arc-shaped shells and the corrugated pipes. When mounting a pipeline, the three segments of arc-shaped shells are covered on the outer wall of the interface of the two segments of the corrugated pipes in a ring shape. The three segments of arc-shaped shells 3 can commonly produce a radial centrifugal force to closely paste the soft sealing cushions which are inlaid on the inner walls of the jaw type arc-shaped shells 3 on outer wall pits of the corrugated pipes after the three segments of arc-shaped shells are closely clamped by fasteners, and the soft sealing cushions which are arranged on the two ends of the arc-shaped shell are also mutually compressed. The outer walls of the two segments of interfaces of the corrugated pipes form a completely closed ring-shaped cavity, thereby preventing liquid or gas in the corrugated pipes from overflowing. Therefore, the joint with the structure has extremely excellent sealing performance.
Description
Technical field
The utility model relates to a kind of joint, particularly three-pawl type joint for corrugated tube that connects with bellows.
Background technique
Bellows is a kind of tube equipment of carrying liquid, gas that is widely used in recent years, its Placement is come usually with telescopic and bayonet joint, and usually there is the fault of easily leaking to some extent in these Placements, and cost is higher and installation inconvenience.
The model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of not only sealability better, and cheap, three-pawl type joint for corrugated tube very easily is installed also.
To achieve these goals, the technological scheme that the utility model adopted is as follows: a kind of three-pawl type joint for corrugated tube, the pipe clamp that comprises the jointing outer wall that is coated on two sections bellowss, described pipe clamp comprise that the arc shell that three sections shapes are identical and the connection angle of this arc shell are 120 °.
The utility model also has following attached technical characteristics:
Be provided with soft sealing gasket between described arc shell and the bellows.
Described soft sealing gasket is close on the outer wall groove hole of described bellows.
The inwall of described arc shell is provided with a restraining groove corresponding to place, described groove hole, and described soft sealing gasket is located in this restraining groove.
The longitudinal end of each described arc shell is equipped with an outer rotating edge, is equipped with a fastening piece between every two adjacent outer rotating edges.
Described outer rotating edge is provided with the through hole that allows fastening piece to pass.
Be provided with soft sealing gasket between described two outer rotating edges.
Relative prior art, the beneficial effects of the utility model are: described pipe clamp comprises that the arc shell that three sections shapes are identical and the connection angle of this arc shell are 120 °.Therefore, three sections arc shells have formed the three-pawl type joint, its can common produce one radially centripetal force and the soft sealing gasket that will be embedded in pawl formula member inwall is close on the outer wall groove hole of bellows, the soft sealing gasket at arc shell two ends is also compressed mutually simultaneously.So formed the annular chamber of a complete closed on the bellows two segment interface outer walls, thereby prevented that liquid or gas in the bellows from overflowing outward.Therefore, its sealing effect is very good, and cheap, easy for installation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a corrugated pipe connector axial cross section structural representation.
Fig. 2 is the local enlarged diagram at P place among Fig. 1.
Fig. 3 is the corrugated pipe connector scheme of installation.
Embodiment
As shown in Figure 1 to Figure 3, a kind of preferred embodiment that provides for the utility model, a kind of three-pawl type joint for corrugated tube, the pipe clamp 2 that comprises jointing 10 outer walls that are coated on two sections bellowss 1, described pipe clamp comprise that the arc shell 3 that three sections shapes are identical and the connection angle of this arc shell are 120 °.It is simple in structure, cheap, installs also very convenient.
In order to strengthen the sealing effect between pipe clamp 2 and the bellows 1, between described arc shell 3 and bellows 1, be provided with soft sealing gasket 4.This soft sealing gasket 4 is close on the outer wall 11 grooves hole 12 of described bellows 1.For the fixed-site that makes described soft sealing gasket, difficult moving, to cheat 12 places at the inwall of described arc shell 3 corresponding to described groove and be provided with a restraining groove 31, described soft sealing gasket 4 is located in this restraining groove.
The longitudinal end of each described arc shell 3 is equipped with an outer rotating edge 30, is equipped with a fastening piece 5 between every two adjacent outer rotating edges.Described outer rotating edge 30 is provided with the through hole 51 that allows fastening piece 5 to pass.So just can tighten together every two neighboring sections arc shell 3 mutually.
Be provided with soft sealing gasket 4 between described two outer rotating edges 30.To strengthen sealing effect to every adjacent two arc shells 3 connecting parts.
The connection angle of arc shell 3 is 120 °, respectively is provided with a plurality of holes 51 that are used to install clamping bolt on the outer rotating edge 30 at the radially two ends of arc shell.Three sections arc shells have formed the three-pawl type joint, and when bellows 1 was installed, three sections arc shells covered on the outer wall 11 of two sections bellows 1 interfaces 10 circlewise.After fastening piece 5 clamps three sections arc shells 3, three sections arc shells 3 can produce jointly one radially centripetal force and the soft sealing gasket 4 that will be embedded in pawl formula arc shell 3 inwalls is close on the outer wall 11 grooves hole 12 of bellows 1, the soft sealing gasket 4 at arc shell 3 two ends is also compressed mutually simultaneously.So formed the annular chamber of a complete closed on 1 liang of segment interface 10 outer wall of bellows, thereby prevented that liquid or gas in the bellows 1 from overflowing outward.Thus, the sealability of the joint of the utility model structure is very good.
