Abstract

The utility model relates to a coupling hoop for a pipeline for coupling the pipeline, which is composed of an upper half hoop ring, a lower half hoop ring, a sealing pad, two hoop ring bolts and a symmetrical left and a right hoop disks. The hoop disk is made up of an outer pipe body and an inner disk body as a whole; the diameter of the disk body is larger than the diameter of the pipe body; the end of the disk body is a plane surface; the coupling part of the disk body and the pipe body is a conical surface. The cross-section of the half hoop ring forms a V shape; an inner conical surface of the half hoop ring is matched with an outer conical surface of the disk body; the sealing pad is clamped between the ends of the disk bodies of the left and the right hoop disks; the upper and the lower half hoop rings are sheathed on the disk bodies of the left and the right hoop disks and are coupled as a whole by the two hoop ring bolts. The utility model has the advantages of small size, light weight and labor-saving and time-saving assembly and disassembly.

Description

Coupling for pipeline

The utility model relates to a kind of coupling for pipeline, belongs to pipeline connecting device.

In pipework, need to be connected between pipe and the pipe.Traditional connection realizes by a pair of flange plate, each flange plate respectively with a pipe welding, between two flanges with how fastening to bolt and nut.Its shortcoming is that volume is big, weight is big, the managed fluid pressure influence of bolt is big, not only require great effort but also time-consuming during dismounting.

In view of above-mentioned, the utility model will provide the coupling for pipeline that a kind of volume is little, in light weight, installing/dismounting is time saving and energy saving.

For reaching this purpose, the utility model by the following technical solutions:

Coupling for pipeline by last second garter spring, gasket seal, two garter spring bolts, symmetry about the hoop dish form, wherein: the hoop dish is made into integration by outside body and inboard disk body, the disk body diameter is greater than pipe diameter, and the end of disk body is the plane, and the joint of disk body and body is the conical surface; The section of half garter spring is V-shaped, and the male cone (strobilus masculinus) of its inner conical surface and disk body matches; About gasket seal is clipped between the end of the disk body of hoop dish; About going up second garter spring and being enclosed within on the disk body of hoop dish, and link into an integrated entity by two garter spring bolts.

Below in conjunction with drawings and Examples the utility model is elaborated.

Fig. 1 is a structural drawing of the present utility model;

Fig. 2 is an axial sectional view of going up second garter spring.

See also accompanying drawing, the utility model by last second garter spring 1 and 2, gasket seal 6, two garter spring bolts 5, symmetry about the hoop dish form.Wherein: about the hoop dish be made into integration by outside body 4 and inboard disk body 3, the diameter of disk body 3 is greater than the diameter of body 4, the end of disk body 3 is the plane, disk body 3 is the conical surface with the joint of body 4; The section of going up second garter spring 1 and 2 is V-shaped, and the male cone (strobilus masculinus) of its inner conical surface and disk body 3 matches.Go up on second garter spring and establish inner bolt hole, establish the plane of being convenient to dismantle two garter spring bolts 5 on first garter spring.

When desire connects, earlier with about the body portion 4 of hoop dish be welded on respectively on the pipe that two desires connect, about gasket seal 6 is clipped between the end of the disk body 3 of hoop dish after, about second garter spring 1 and 2 is enclosed within on two disk bodies 3 of hoop dish, with about the hoop dish link together, will go up second garter spring 1 and 2 with two garter spring bolts 5 at last and link into an integrated entity.In the process of fastening two garter spring bolts 5, along with the slit between last second garter spring 1 and 2 reduces gradually, about hoop dish the bearing against of inner conical surface that be subjected to second garter spring because of the male cone (strobilus masculinus) of its disk body, can be from two towards middle crush seal pad 6, thus realize connection and sealing between pipe.

When the male cone (strobilus masculinus) of the inner conical surface of last second garter spring and disk body during with cone angle and how much symmetries, the hoop dish is stressed the most even, the stressed minimum of garter spring bolt, and the sealing effect between pipe is best.

Go up second garter spring and about the material of hoop dish can select forged steel or stainless steel for use.

The utility model is connected with ring flange and has the following advantages: two bolts are only arranged, easy accessibility 1.; 2. bind round Dish is subjected to power even, and its conical surface specific pressure is little; 3. the two halves garter spring closed up about the garter spring bolt just made, thereby was subjected to power little; 4. volume is little, weight is light, and material consumption is 40～50% of ring flange.
