Description

Flange strutting arrangement

Technical Field

The utility model provides a flange struts ware belongs to valve pipe way equipment.

Background

In pipeline equipment, a flange is used for connecting a pipe end and a pipe end, a valve is commonly used between the flange and the flange to cut off and adjust media, a flange gasket is placed between the valve and the flange to seal in order to prevent leakage, and the flange gasket needs to be replaced regularly due to corrosion of the media and damage of the external environment so as to avoid leakage damage. In the replacement process, a crow bar or other tools are often needed to prop open the pipeline flange, so that the operation is labor-consuming and time-consuming, and the working efficiency is low; and the operators are easy to be damaged in the operation process, and certain potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

The utility model provides a flange strutting arrangement can solve the technical problem that the above-mentioned exists.

For the aforesaid problem of solving, the utility model adopts the following technical scheme: a flange opening device comprises a first operation module and a second operation module. The first operation module and the second operation module are identical in appearance and appearance size and are of U-shaped structures, and the back surfaces of the U-shaped structures are provided with protruding structures. The center of the raised structure on the back of the U-shaped structure of the first operation module is provided with an internal threaded hole; the center of the protruding structure on the back of the U-shaped structure of the second operation module is provided with a circular sinking platform, and the circular sinking platform is coaxial with the internal thread hole.

The back of the U-shaped structure of the first operation module is provided with a raised internal thread hole matched with the screw rod, one end of the screw rod is provided with a nut, and the nut and the screw rod are welded into a whole.

The operation process in the technical scheme is as follows: the first operating module and the second operating module are respectively arranged on two pipe end flanges and are stably clamped on the flanges. And adjusting a screw rod on the back surface of the U-shaped structure of the first operation module to be matched with a circular sinking platform on the back surface of the U-shaped structure of the second operation module, and screwing the screw rod to expand the flange to a required position.

The utility model provides a device compares in current method has following advantage: simple structure, easy operation, portable, safe and reliable in the operation process has mentioned work efficiency greatly.

Fig. 2 is a front view and a right side view of the first operating module.

Fig. 3 is a front view and a right side view of the second operation module.

In the figure: 1. the flange 2, the second operation module 3, the screw rod 4, the nut 5, the first operation module 2-1, the circular sinking platform 5-1 and the internal thread hole.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A flange opening device is shown in figure 1, wherein a central position of a protruding structure on the back of a U-shaped structure of a first operation module 5 is provided with an internal threaded hole 5-1, a screw rod 3 matched with the internal threaded hole is arranged in the internal threaded hole, and a nut 4 and the screw rod 3 are welded into a whole. The second operation module 2 has the same size with the first operation module 5, and a circular sinking platform 2-1 is arranged at the center of the protruding structure on the back of the U-shaped structure and is used for being matched with the internal thread hole 5-1.

The protruding internal thread hole 5-1 of the back of the U-shaped structure of the first operation module 5 is coaxial with the protruding circular sinking platform 2-1 of the back of the U-shaped structure of the second operation module 2.

In use, as shown in fig. 1, the first operating module 5 and the second operating module 2 are respectively clamped on the pipeline flange 1, and the U-shaped structure is required to be only clamped on the flange.

Furthermore, the screw rod 3 is adjusted to be matched with the circular sinking platform 2-1 on the second operation module 2, and the nut 4 at the tail end of the screw rod 3 is screwed to achieve the distance required by the opening of the flange.

Finally, it is noted that the above examples are only intended to illustrate the technical solutions of the present invention and not to limit the same, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
