Abstract
The utility model relates to a sealing structure of a unit steel pipe expansion joint connected by adopting expansion joints. The composition of the utility model comprises: the inner side of the expansion joint is sequentially filled with a rubber pipe and at least two circles of U-shaped packing, the front end of the U-shaped packing at the innermost circle is lapped on the rubber pipe, the front end of the U-shaped packing at the outer circle is lapped with the tail end of the U-shaped packing adjacent to the U-shaped packing, and rubber rollers are filled in the U-shaped packing at each circle. The utility model adopts the structure of at least two U-shaped packing to seal, the steel pipe expansion joint is not permeated with water when the machine set is operated after the installation, and the rubber rods are filled in the U-shaped packing to tightly cling to the two sides of the expansion joint at the top of the U-shaped packing, thereby reducing the water leakage of the steel pipe.
Description
Technical Field
The utility model relates to a sealing structure of a unit steel pipe expansion joint connected by adopting expansion joints.
Background
The gap distribution of the steel pipe expansion joint of the conventional unit is uneven, the maximum difference is more than 15mm, the packing is filled with oil hemp, the packing is seriously worn due to uneven gaps during filling, and water can leak from the expansion joint after the unit operates for a period of time.
Disclosure of Invention
The utility model aims to solve the problems and provide a sealing structure for a unit steel pipe telescopic joint connected by adopting the telescopic joint.
The above object is achieved by the following technical scheme:
a unit steel pipe telescopic joint sealing structure adopting telescopic joint connection comprises the following components: the inner side of the expansion joint is sequentially filled with a rubber pipe and at least two circles of U-shaped packing, the front end of the U-shaped packing at the innermost circle is lapped on the rubber pipe, the front end of the U-shaped packing at the outer circle is lapped with the tail end of the U-shaped packing adjacent to the U-shaped packing, and each circle of U-shaped packing is filled with a rubber rod.
The unit steel pipe telescopic joint sealing structure adopting telescopic joint connection, and the front end of the U-shaped packing is an inclined opening.
The unit steel pipe telescopic joint sealing structure adopting telescopic joint connection, and the opening of the U-shaped packing faces the water incoming direction.
Advantageous effects
1. The utility model adopts the structure of at least two U-shaped packing to seal, the steel pipe expansion joint is not permeated with water when the machine set is operated after the installation, and the rubber rods are filled in the U-shaped packing to tightly cling to the two sides of the expansion joint at the top of the U-shaped packing, thereby reducing the water leakage of the steel pipe.
2. The inclined opening is arranged on the U-shaped packing, so that the U-shaped packing can be conveniently installed in a gap of the steel pipe expansion joint, water flows into the middle of the U-shaped packing along the inclined opening when leakage occurs, and two sides of the U-shaped packing are pressed towards the edge of the expansion joint by water pressure.
3. The U-shaped packing opening is completely blocked by the U-shaped packing when water flows outwards in the water inflow direction, the U-shaped packing is opened to two sides along with the increase of water pressure, the U-shaped packing is tightly attached to the edge wall of the expansion joint, and the sealing is better when the water pressure is larger.
4. The rubber pipe is arranged at the innermost end of the expansion joint, is tightly pressed at the opening of the expansion joint, and blocks the steel pipe after being pressed to prevent a large amount of water from leaking.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
in the figure: 1. an expansion joint; 2. a rubber tube; 3. a steel pipe; 4. u-shaped packing; 5. rubber roller.
Detailed Description
Referring to fig. 1, a steel pipe expansion joint sealing structure of a unit adopting expansion joint connection, the composition comprises: the inner side of the expansion joint is sequentially filled with a rubber pipe and at least two circles of U-shaped packing 4, the front end of the U-shaped packing at the innermost circle is lapped on the rubber pipe and positioned at the outer circle, the front end of the U-shaped packing is lapped with the tail end of the U-shaped packing adjacent to the U-shaped packing, the front end of the U-shaped packing is a bevel connection, the bevel connection is used for lapping, and a rubber roller 5 is filled in the U-shaped packing at each circle.
Claims (3)
