Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated pipes, and in particular relates to a corrugated pipe for drainage. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as measuring elements of pressure measuring instruments to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, with a measuring range of tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase elasticity. When working, it stretches along the length of the tube under the action of internal pressure, causing the movable end to produce a displacement that is related to the pressure. The movable end drives the pointer to directly indicate the size of the pressure. Bellows are often combined with displacement sensors to form pressure sensors with output as electrical quantity, and are sometimes used as isolation elements. Since the extension of bellows requires a larger volume change, its response speed is lower than that of Bourdon tubes. Bellows are suitable for measuring low pressures.

[0003] At present, people use bellows more and more commonly, and they are often used for drainage of washing machines. However, people often ignore whether there are items in their pockets when washing clothes. After washing clothes, paper towels, coins, etc. in the pockets will be washed out and discharged from the bellows. Since paper objects will become heavier when they meet water, this may cause paper towels and other objects to settle inside the bellows, forming a blockage, which is difficult to use. For this reason, the utility model provides a bellows for drainage. Utility Model Content
