Embodiment 1

[0023] The closed elastic compensating bushing of the present invention is formed by fitting a bushing 2 on the wall-penetrating pipe 1, the end of the bushing 2 and the pipe 1 are closed and connected by an elastic pipe 3, and fixed on the bushing 2 The water stop plate 4 is fixed in the body of wall.

Embodiment 2

[0025] The closed elastic compensating sleeve of the present invention is composed of a sleeve 2 sleeved on the wall-through pipe 1, and the end of the sleeve 2 and the pipe 1 are closed and connected by the end of the elastic element 3 and the flange 6. The fixed water stop plate 4 on the pipe 2 is clamped in the body of wall.

Embodiment 3

[0027] In the closed elastic compensating casing of the present invention, a casing 2 is set on the wall-through pipe 1, an adjustable casing 2-1 is set on the casing 2 to form a stepped casing, and bellows are used at both ends of the casing. 3 is closed and fixedly connected with the pipeline 1, and the water stop plate 4 fixed on the sleeve 2 is placed in the wall 5 together with the stepped sleeve.

Abstract

The invention aims to overcome the defects of the prior art and provides a sealed elastic compensation sleeve with reliable quality, no leakage, low cost and long service life. In the sealed elastic compensation sleeve, a sleeve is sleeved on a wall penetrating pipeline, the end of the sleeve and the pipeline are connected in a sealing way by an elastic pipe fitting, and a water-stop plate is fixed on the sleeve and embedded into a wall and connected with the pipeline into a whole. Thereby the invention realizes the function of elastic compensation and achieves the sealing effect without leakage.

Description

technical field [0001] The invention relates to a closed elastic compensating sleeve. Background technique [0002] At present, new or built underground pools, valve wells, underground pump rooms, underground bunkers, underground warehouses, tunnels and residential buildings and other industrial and civil buildings, the casing of the wall pipeline of the structure and the underground passage casing are widely used. Linseed cement seals the wall casing, flexible casing and various pipe expanders installed on the main pipe. However, its sealing effect is not good, frequent leakage, high installation accuracy requirements, short service life, and high cost lead to a decrease in the quality of the main structure and a shortened service life, resulting in huge waste and losses. Contents of the invention [0003] The invention is a closed elastic compensating casing scheme with reliable quality, no leakage, low cost and long service life. The closed elastic compensating casing...
