A container of beautifully packed layflat hose will be delivered
This hose refers to a tubular elastic sensitive element connected by foldable sheets along the direction of fold and stretch. Bellows are widely used in meters. While their main purpose is as a measure element to convert pressure into force. The bellows has a thinner wall as well as a higher sensitivity. Thus the measure range can be dozens of Mpa. Its has a fixed open, while the sealed end is in a free state. In addition, it use the auxiliary coil spring or reed to improve the elasticity.
What are bellows
In the work, under the action of internal pressure, it is elongated along the length of the pipe. So that the movable end makes a displacement that relate the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often to form a pressure sensor whose output is electricity. In some case, it works as an isolation element. Bellows respond slower than Bourdon tubes. Because of the large volume change required to expand. Besides, bellows are suitable for low pressure measure.
Types of bellow
Bellows mainly include metal bellow, expansion joints, heat exchange tubes, and metal hose. Metal bellows are mainly used to absorb shock. While it widely serves in petrol, aerospace, chemical, electric power, cement and other places. Plastic and other materials hose play an part role in the fields of medium transfer and electric thread machine.
