Description of the Invention (1) The technical field to which the invention belongs The present invention relates to a liquid valve, especially a liquid valve used in a fabric processing machine. The yarn used in the manufacture of fatty fabrics is generally wound on a perforated tube or a grooved spool to form a permeable package through which the dye liquor can be circulated during the dyeing process. During the dyeing process, the permeable package is mounted on a perforated mandrel in a package carrier, where the package carrier is immersed in the dye solution during the dyeing process. In practice, eight or nine packages are typically stacked on multiple mandrels. A sealing dish was then placed on top of each package cylinder, and it was locked above the mandrel to make the package top impervious to water. The encapsulation dyeing process involves passing a dye solution or other treatment solution through a permeable package. In order to achieve uniform coloration of the entire thickness of the yarn package, the dye liquor is usually passed in two opposite directions; that is, the inside flows outward and the outside flows inward. Inside-out flow means that the dye solution flows from the packaged perforated core through the yarn to the outside of the package. Conversely, an inward flow means that the dyeing solution flows into the perforated core of the package from the outside of the package via the yarn. Package dyeing machines generally include a pump and a reverse valve to facilitate reversible flow of the treatment liquid. The pump generally includes a centrifugal pump because this pump can provide high pressure and high flow rate to overcome the high resistance of the yarn package to the dye liquor flow. However, centrifugal pumps can generally only be operated in one direction. Therefore, a valve is used to promote reversible flow. Generally used flow reversible valves require excess external piping to facilitate reversible flow of liquid. Such a valve has disadvantages in design, because (please read the precautions on the back before filling this page) This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm) -4- 565645 A7 __ __ B7 V.

Description of the invention (11) Detailed description of the preferred embodiment Figures 1, 2a and 2b show a liquid flow reversible device 100, including (please read the back first Precautions then fill page) --h shaped tube 1, a rotatable closure member 2 is mounted on a shaft 3, an outer tube 6 and a housing 7. The cross pipe 1 includes a first pipe 30 and first and second pipe sections 32 and 34 extending substantially perpendicular to the first pipe 30. The first and second tube sections 32, 34 extend from opposite sides of the first tube 30 and are aligned in the axial direction. The first opening 36 and the second opening 38 in the side wall of the first pipe 30 can ensure that the first pipe section 32 and the second pipe section 34 are in communication with the first pipe 30, respectively. The cross tube 1 has four ports 11, 12, 16, and 17. Port 16 of the first pipe 30 extends into the inside of the outer pipe 6, so that the cross pipe 1 is connected to the outer pipe 6 through the port 16. The port 12 of the cross tube 1 is connected to the liquid inlet of the centrifugal pump 5. An impeller 4 is placed in the centrifugal pump 5. The centrifugal pump 5 is driven by an external motor 10. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The outer tube 6 has an outer diameter larger than that of the first tube 30. The outer pipe 6 is arranged concentrically with the first pipe 30 of the cross pipe 1. The first end 46 of the outer tube 6 is connected to the heat exchange tube 51 in the heat exchanger 50 at one end. The other end of the heat exchanger tube 51 is connected to the liquid outlet of the centrifugal pump 5. The second end 48 of the outer tube 6 is welded to the casing 7. The wall of the casing 7 has a curved profile 23 where the outer tube 6 is welded. The ends of the first tube section 32 and the second tube section 34 each extend through opposite sides of the outer tube 6. The casing 7 has a cylindrical shape. One end of the case 7 is closed and the paper size of the paper is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). For a base 4 4. The other end of the case 7 is provided with a plurality of perforations 18 to allow liquid to flow between the outside and the inside of the case 7. The first tube section 32 of the cross tube 1 extends through the full height of the casing 7 so as to penetrate the perforated end of the casing 7, thereby allowing liquid to flow between the inside of the first tube section 3 and the outside of the casing 7. The shaft 3 of the closure member 2 is controlled by a motor (not shown), which is located outside the housing. The closure member 2 can be rotated between a first position (shown in FIG. 1) and a second position (shown in dotted lines in FIG. 1). Figures 2a and 2b show a situation where the liquid flow reversible device 100 is connected to a dyeing liquid container 19 of a yarn dyeing machine (not shown). The arrows indicate the direction of liquid flow. When the closing member is in the first position, as shown in Fig. 2a, liquid will flow from the inside to the outside of the yarn package 22 in the dyeing container 19. The centrifugal pump 5 generates a suction force to attract the liquid through the first pipe 30 and the port 12 of the cross pipe 1. The liquid is discharged from the centrifugal pump 5 and passes through the heat exchange pipe 51 in the heat exchanger 50, and then enters a ring-shaped passage 14 provided between the first pipe 30 and the outer pipe 6. As can be seen from Figures 2a and 2b, the direction of the suction flow is approximately parallel to the direction of the discharge flow. The liquid enters the rotation chamber 15 provided between the wall of the housing and the port 16 of the first pipe 30. The curved shape 23 of the wall of the casing at this position enables the liquid to flow smoothly from the annular channel 14 into the port 16. The liquid is diverted by the closing member 2 so as to flow upward through the cross tube 1 of the cross tube 1 and flows out of the casing 7 into the package holder 20 of the dyeing machine. The liquid flows into the perforated core 21 of each package 22, and the size of the paper wound on the core 22 is adapted to the Chinese National Standard (CNS) A4 specification (210 × 297 mm) — -15- (Please read the note on the back first (Fill in this page again)
