The invention discloses a dyeing rack for tatting yarn, zippers, ropes, ribbons and loose fibers of loading needles of a dyeing machine. The dyeing rack for tatting the yarn, the zippers, the ropes, the ribbons and the loose fibers of the loading needles of the dyeing machine comprises a yarn plate, a suspender and a yarn rod. The upper surface of the yarn plate is in a disc shape. The lower end of the yarn plate is in a cavity structure. A center seat of the dyeing machine is connected with the bottom of the lower end of the yarn plate. A yarn plate water outlet, a yarn plate water return hole and a suspender hole seat are formed in the upper surface of the yarn plate. The suspender hole seat is arranged at the center of the yarn plate. A suspender is fixedly installed in the suspender hole seat. The bottom of the yarn rod is fixed on the yarn plate water outlet of the upper surface of the yarn plate. The yarn rod is in a solid structure or a hollow structure. A gap is reserved between a to-be-dyed object and the yarn rod. Dye liquor flows out of the yarn plate water outlet hole of the bottom of the yarn rod and fills the gap to form a hollow water column. The dye liquor permeates the to-be-dyed object through flowing of the hollow water column. The dye liquor permeated from the to-be-dyed object flows into the yarn plate water return hole. A bolt at the upper end of the yarn rod is provided with a gravity tapered end. The dyeing rack for tatting the yarn, the zippers, the ropes, the ribbons and the loose fibers of the loading needles of the dyeing machine is simple in structure, capable of reducing consumption of dye, auxiliaries, energy sources and water resources, and capable of improving dyeing efficiency.

The invention provides sarong transportation equipment, which comprises a first beam, a second beam, a mechanical claw, a position detection unit and a control device, wherein the first beam is arranged on a guide rail and can move along the guide rail; the second beam is movably arranged on the first beam and can move along the first beam; the mechanical claw is arranged on the second beam and comprises a telescoping mechanism and a grabbing mechanism connected with the telescoping mechanism; the position detection unit is used for detecting the positions of the first beam and the second beam; and the control device is used for controlling the movements of the first beam, the second beam and the mechanical claw according to the position information detected by the position detection unit. The sarong transportation equipment can automatically transport sarongs through the control device and the mechanical claw, thereby improving the production efficiency and the safety of the dye production and reducing the personnel cost.

The present invention provides a fluid flow reversal device (100) comprising a first conduit (1), the first conduit (1) having a cross-shaped configuration provided by a first arm (30) and a second arm (32, 34) thereof, a second conduit (6), which second conduit (6) is concentrically arranged about the first arm (30) of the first conduit (1), the second arm (32, 34) of the first conduit (1) being arranged to extend through opposing sides of the second conduit (6), and a valve (2, 3) designed to control the direction of fluid flow through the second arm (32) of the first conduit (1), in use.
