A bellows is an elastic sensitive component in the form of a tube, made by connecting foldable corrugated sheets along the direction of expansion and contraction. Bellows are widely used in instruments and meters, primarily serving as measuring elements for pressure gauges, converting pressure into displacement or force. The wall of a bellows is thin and highly sensitive, with a measurement range of tens to tens of megapascals. Its open end is fixed, while the sealed end is free, and it utilizes auxiliary helical springs or leaf springs to enhance elasticity. During operation, under the action of internal pressure, it extends along the length of the tube, causing the movable end to produce a displacement proportional to the pressure. The movable end drives a pointer, which directly indicates the magnitude of the pressure. Bellows are often combined with displacement sensors to form pressure sensors with electrical output, and they are also sometimes used as isolation elements. Due to the bellows' requirement for a larger volume change during expansion, their response speed is lower than that of Bourdon tubes. Bellows are suitable for measuring low pressure.

Y-type filters are an indispensable filtering device in pipeline systems for conveying media. They are commonly installed at the inlet of pressure-reducing valves, pressure-relief valves, level control valves, or other equipment to remove impurities from the medium, thereby protecting valves and equipment from malfunction. Y-type filters feature good structure, low resistance, and easy waste discharge. They are suitable for media such as water, oil, and gas. The mesh size for water flow is typically 18-30 mesh, for gas flow 10-100 mesh, and for oil flow 100-480 mesh. Basket filters are mainly composed of inlet pipes, main pipes, filter baskets, flanges, flange covers, and fasteners. When liquid passes through the main pipe into the filter basket, solid impurities are trapped inside, while the clean fluid flows through the basket and exits via the filter outlet.
