Description

Low-temperature carbon steel flange

Technical Field

The utility model relates to a flange technical field especially relates to a low temperature carbon steel flange.

Background

The flange is a part for connecting the shaft and the shaft, and is mainly used for connecting pipe ends. The flange comprises products such as an integral flange, a butt welding annular plate type loose flange, a flat welding annular plate type loose flange, a flanging annular plate type loose flange, a flange cover and the like. With the upgrading and development of manufacturing technology in related fields, some fields have special requirements on the installation and connection of flanges, and standard flange parts cannot meet related requirements. When a flange product is connected with a rotating shaft, the connection tightness cannot be guaranteed by a rigid connection mode, and therefore a low-temperature carbon steel flange is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a low-temperature carbon steel flange.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a low temperature carbon steel flange, includes the end face dish and fixes the axle sleeve that sets up in end face dish one side quotation, set up the mounting hole that is used for connecting in the quotation of end face dish, the cross incision groove is seted up along the axial in its surface of keeping away from the end face dish to the surface round of axle sleeve is provided with the nut that circumference distributes, and nut female connection has locking screw, and locking screw all radially sets up, locking screw runs through the surface of axle sleeve and extends to the inside of axle sleeve.

Preferably, the outer wall of the shaft sleeve is provided with a plurality of same through holes, the through holes are all positioned on each outer wall surface separated by the notch grooves and are circumferentially arranged on the shaft sleeve.

Preferably, the outer end face of the through hole is fixedly provided with an installation seat, the nut is fixedly arranged on the installation seat, and a locking screw is inserted into the nut and penetrates through the through hole and extends into the shaft sleeve.

Preferably, the end face disc is provided with a circular sealing groove in the center of the disc face on one side far away from the shaft sleeve.

Preferably, a sealing gasket is embedded in the sealing groove.

The utility model has the advantages that: through the flange that this scheme provided, solved standard class flange with the rotation axis connecting axle, can't guarantee to connect inseparable problem, the improvement of this flange structure, cross incision groove has increased the flexibility degree that flange and rotation axis are connected, it is comparatively convenient to install, and simple structure, low in manufacturing cost is fit for batch production and uses.

In the figure: 1. an end face plate; 2. mounting holes; 3. a shaft sleeve; 4. a notch groove; 5. a mounting base; 6. a nut; 7. locking screws; 8. a gasket; 9. the groove is sealed.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the embodiment, referring to fig. 1-2, a low-temperature carbon steel flange comprises an end face disc 1 and a shaft sleeve 3 fixedly arranged on a disc surface on one side of the end face disc 1, a mounting hole 2 for connection is formed in the disc surface of the end face disc 1, a cross-shaped notch groove 4 is formed in the surface, away from the end face disc 1, of the shaft sleeve 3 along the axial direction, a nut 6 distributed in the circumferential direction is arranged on the circle of the outer surface of the shaft sleeve 3, a locking screw 7 is connected to the nut 6 in an internal thread mode, a plurality of identical through holes are formed in the outer wall of the shaft sleeve 3, the through holes are located in each outer wall surface separated by the notch groove 4 and are formed in the shaft sleeve 3 in the circumferential direction, a mounting seat 5 is fixedly arranged on the outer end face of each through hole, the nut 6 is fixedly arranged on the mounting seat 5, the locking screw 7 is inserted into the nut 6, and the locking screw 7 penetrates through the through holes and extends into the shaft sleeve 3.

The locking screws 7 are all arranged in the radial direction, and the locking screws 7 penetrate through the outer surface of the shaft sleeve 3 and extend to the inside of the shaft sleeve 3. The end face disc 1 is provided with a circular sealing groove 9 in the center of the disc face on one side far away from the shaft sleeve 3, and a sealing gasket 8 is embedded in the sealing groove 9.

The shaft sleeve 3 for holding tightly is used for being flexibly connected with a rotating shaft, and the cross notch groove 4 extends to the end part of the shaft sleeve 3, so that the effect of flexibly fastening, installing and connecting the carbon steel flange and the rotating shaft is favorably improved. Here, two nuts 6 are provided on each side, and in other embodiments, the number of nuts 6 can be adjusted and changed as required. Finally, the end face plate 1 is fixedly mounted on the corresponding connecting workpiece, and the sealing gasket 8 is used for achieving the effect of sealing assembly.
