[0012] A process for using a control valve for toiletries is also provided, which is used to operate a control valve for the production of toiletries, and includes the following steps: S1: When disassembling the diaphragm, first rotate the knob to drive the worm, driving the two sets of notched tubes to rotate 180 degrees, blocking the upper delivery port. At the same time, the blocking block is turned to the upper position, and the semicircular port is opened, communicating with the inside of the flange pipe, meeting the internal delivery of liquid materials for toiletries; S2: The diaphragm is then driven downward by the hand wheel to squeeze the material between the diaphragm and the notched tube, open the fixed sleeve and the liquid outlet, and then enter the inner side of the flange tube through the liquid outlet to reduce the material between the diaphragm and the notched tube; S3: The diaphragm is controlled to move up and down by the hand wheel to open and close the inside of the flange pipe. When disassembling, the diaphragm can be disassembled by removing the bolts on the upper valve shell and the lower valve shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The handwheel drives the threaded shaft to rotate, so that the connecting sleeve and the piston block push the diaphragm downward, and the diaphragm is pressed against the upper end of the partition block to realize the partition of the two sides of the delivery port. The reversal pulls up the diaphragm to transport the delivery port and the inside of the flange pipe. After removing the bolts connecting the upper valve shell and the lower valve shell, the upper valve shell can be removed. After removing the threaded shaft and the connecting sleeve, the fixing bolt, the piston block and the diaphragm can be removed to realize the disassembly of the diaphragm, which is convenient for replacing the diaphragm that has been damaged by long-term work.

[0014] When disassembling the diaphragm, it is necessary to first rotate the knob block to drive the worm to rotate on the inside of the cylinder, driving the two engaged worm gears and the two connected notched tubes to rotate one hundred and eighty degrees in the groove, and the setting of the limit strip prevents the notched tube from being driven to rotate too much. At this time, the upper notch of the notched tube moves to the lower position, and the upper conveying port is blocked at the same time. After the two rotating notched tubes drive the two sets of blocking blocks to rotate one hundred and eighty degrees respectively, the blocking blocks are turned to the upper position, and the semicircular port is opened, communicating with the inside of the flange pipe, meeting the internal conveying of liquid materials of toiletries, avoiding shutdowns for replacing the diaphragm, and improving work efficiency.

[0015] After switching the inside of the notch tube, the diaphragm is driven by the handwheel to press close to the partition block for holding operation. Since the two groups of notch tubes are rotated one hundred and eighty degrees, the delivery port is sealed. When the diaphragm is not closed, the diaphragm is in an upward convex state. When the upper valve shell is opened directly, the material between the diaphragm and the notch tube will overflow, resulting in material waste. Therefore, the diaphragm is first driven downward by the handwheel to press the partition block. The material between the diaphragm and the notch tube will push the movable plug to move toward the inside of the threaded barrel during the extrusion process, so that the circular shaft drives the sealing plug to open several groups of liquid outlets and squeeze the reset spring at the same time. The material flows from the fixed sleeve liquid inlet in one direction into the threaded barrel and the liquid outlet, and then enters the inside of the flange tube through the liquid outlet, reducing the material between the diaphragm and the notch tube and avoiding waste of excess material when opening the upper valve shell.

[0021] The inner side of the partition block 3 corresponds to the notch tube 56 located in a circular cavity, the semicircular opening 53 coincides with the two sets of blocking blocks 510, the notch tube 56 and the support ring 57 are respectively fitted on the inner side of the groove 55, the worm gear 58 is located on the inner side of the annular groove 51, the lower side of the worm gear 58 partially passes through the inner side of the communicating opening 54, the shaft block 511 is correspondingly arranged at the center position of the worm gear 58, the control rod 516 passes through the bottom cover plate 513 and the inner side of the square groove 514, and the worm 517 is meshed with the two sets of worm gears 58.

[0022] When disassembling the diaphragm 8, it is necessary to first rotate the knob block 518 to drive the worm 517 to rotate on the inner side of the cylinder 515, driving the two engaged worm gears 58 and the two connected notched tubes 56 to rotate one hundred and eighty degrees in the groove 55, and the setting of the limit bar 512 prevents the notched tube 56 from rotating too much. At this time, the upper notch of the notched tube 56 moves to the lower position, and at the same time blocks the upper delivery port 4. After the two rotating notched tubes 56 drive the two sets of blocking blocks 510 to rotate one hundred and eighty degrees respectively, the blocking blocks 510 turn to the upper position, and the semicircular port 53 is opened and communicated with the inside of the flange tube 1, so as to meet the internal transportation of the liquid materials of the toiletries, avoid stopping work to replace the diaphragm 8, and improve work efficiency.

[0023] The liquid inlet component 6 includes two groups of fixed sleeves 61 fixedly arranged on the inner side of the notched tube 56, and a threaded barrel 62 is installed on the inner side of the fixed sleeve 61. An upper circular ring 63 is fixedly arranged on the inner wall of the upper side of the threaded barrel 62. Several groups of liquid outlets 64 are opened around the upper side of the threaded barrel 62 near the outer side of the upper circular ring 63. A circular shaft 65 is movably arranged at the center of the threaded barrel 62, and a sealing plug 66 is fixedly arranged on the upper end of the circular shaft 65. A movable plug 67 is fixedly arranged on the lower end of the circular shaft 65, and a lower circular ring 68 is fixedly arranged on the upper end of the movable plug 67. A reset spring 69 is sleeved on the inner side of the upper circular ring 63 and the lower circular ring 68 on the outer side of the circular shaft 65.

[0024] The fixed sleeve 61 penetrates the inner side of the notched tube 56 , and a liquid inlet is provided at the bottom of the fixed sleeve 61 . The upper ring 63 is fitted on the inner side of the lower ring 68 . The sealing plug 66 is plugged on the inner side of several groups of liquid outlets 64 . The movable plug 67 is plugged in the opening of the fixed sleeve 61 . The return spring 69 is located between the movable plug 67 and the upper inner wall of the threaded cylinder 62 .

[0025] After the inside of the notched tube 56 is switched, the diaphragm 8 is driven by the handwheel 13 to approach the partition block 3 for a pressing operation. Since the two groups of notched tubes 56 are rotated one hundred and eighty degrees, the delivery port 4 is sealed. When the diaphragm 8 is not closed, the diaphragm 8 is in an upward convex state. When the upper valve shell 7 is directly opened, the material between the diaphragm 8 and the notched tube 56 will overflow, causing material waste. Therefore, the diaphragm 8 is first driven downward by the handwheel 13 to press the partition block 3, and the material between the diaphragm 8 and the notched tube 56 will push the movable plug 67 to move inside the threaded barrel 62 during the squeezing process, so that the circular shaft 65 drives the sealing plug 66 to open several groups of liquid outlets 64 and squeeze the return spring 69 at the same time. The material flows from the liquid inlet of the fixed sleeve 61 into the threaded barrel 62 and the liquid outlet 64 in a unidirectional manner, and then enters the inner side of the flange tube 1 through the liquid outlet 64, reducing the material between the diaphragm 8 and the notched tube 56 and avoiding waste of excess material when the upper valve shell 7 is opened.

[0026] The upper valve housing 7 is fixedly installed on the upper side of the lower valve housing 2 by bolts, and a diaphragm 8 is fixedly arranged between the lower valve housing 2 and the upper valve housing 7. The upper internal thread of the upper valve housing 7 is connected with a threaded shaft 9, and a connecting sleeve 10 is sleeved on the lower side of the threaded shaft 9. A piston block 11 is fixedly arranged on the lower end of the connecting sleeve 10, and a fixing bolt 12 is fixed to the piston block 11 and the inner side of the diaphragm 8 by a thread. A handwheel 13 is fixedly installed on the upper side of the threaded shaft 9.

[0027] The diaphragm 8 is sealed and pressed between the lower valve housing 2 and the upper valve housing 7 , and the movable opening opened on one side of the connecting sleeve 10 is adapted to be moved out from the lower side of the threaded shaft 9 .

[0028] The threaded shaft 9 is driven to rotate by the handwheel 13, so that the connecting sleeve 10 and the piston block 11 push the diaphragm 8 to move downward, and the diaphragm 8 is pressed against the upper end of the partition block 3 to realize the partition of the two sides of the delivery port 4. The reversal pulls up the diaphragm 8 to carry out the delivery between the delivery port 4 and the inside of the flange pipe 1. After removing the bolts connecting the upper valve shell 7 and the lower valve shell 2, the upper valve shell 7 can be removed, and after removing the threaded shaft 9 and the connecting sleeve 10, the fixing bolt 12, the piston block 11 and the diaphragm 8 can be removed to realize the disassembly of the diaphragm 8, which is convenient for replacing the diaphragm 8 that has been damaged by long-term work.

[0029] A process for using a control valve for toiletries is also provided, which is used to operate a control valve for the production of toiletries, and includes the following steps: S1: When disassembling the diaphragm 8, first rotate the knob block 518 to drive the worm 517 to rotate, driving the two sets of notched tubes 56 to rotate 180 degrees to block the upper delivery port 4. At the same time, the blocking block 510 is rotated to the upper position, and the semicircular port 53 is opened to communicate with the interior of the flange tube 1, meeting the internal delivery of the liquid material of the toiletries; S2: The diaphragm 8 is then driven downward by the hand wheel 13 to squeeze the material between the diaphragm 8 and the notched tube 56, opening the fixing sleeve 61 and the liquid outlet 64, and then entering the inner side of the flange tube 1 through the liquid outlet 64, reducing the material between the diaphragm 8 and the notched tube 56; S3: The diaphragm 8 is controlled to move up and down by the hand wheel 13 to realize opening and closing of the interior of the flange pipe 1. When disassembling, the diaphragm 8 can be disassembled by removing the bolts on the upper valve shell 7 and the lower valve shell 2.

[0030] Working principle: When in use, the hand wheel 13 is used to drive the threaded shaft 9 to rotate, so that the connecting sleeve 10 and the piston block 11 push the diaphragm 8 to move downward, and the diaphragm 8 is pressed on the upper end of the partition block 3 to realize the isolation of the two sides of the delivery port 4, and the reversal pulls up the diaphragm 8 to carry out the delivery of the delivery port 4 and the inside of the flange pipe 1. After removing the bolts connecting the upper valve shell 7 and the lower valve shell 2, the upper valve shell 7 can be removed, and after removing the threaded shaft 9 and the connecting sleeve 10, the fixing bolt 12, the piston block 11 and the diaphragm 8 can be removed to realize the disassembly of the diaphragm 8, which is convenient for long-term work and is not damaged. The diaphragm 8 is replaced; in addition, when disassembling the diaphragm 8, it is necessary to first rotate the knob block 518 to drive the worm 517 to rotate on the inner side of the cylinder 515, driving the two meshing worm gears 58 and the two connected groups of notched tubes 56 to rotate 180 degrees in the groove 55, and the setting of the limit bar 512 prevents the notched tube 56 from rotating too much. At this time, the upper notch of the notched tube 56 moves to the lower position, and at the same time blocks the upper delivery port 4. After the rotating two groups of notched tubes 56 respectively drive the two groups of blocking blocks 510 to rotate 180 degrees, the blocking blocks 510 rotate to The upper side position, and the semicircular port 53 is opened, communicating with the interior of the flange pipe 1, meeting the internal conveying of the liquid material of the washing products, avoiding the shutdown to replace the diaphragm 8, and improving the work efficiency; and after the inside of the notch tube 56 is switched, the diaphragm 8 is driven by the hand wheel 13 to be close to the partition block 3 for pressing operation. Since the two sets of notch tubes 56 are rotated 180 degrees, the delivery port 4 is sealed. When the diaphragm 8 is not closed, the diaphragm 8 is in an upward convex state. When the upper valve shell 7 is directly opened, the material between the diaphragm 8 and the notch tube 56 will overflow, causing material waste. Therefore, the diaphragm 8 is first driven downward by the hand wheel 13 to press against the partition block 3, and the material between the diaphragm 8 and the notched tube 56 will push the movable plug 67 to move inwardly of the threaded barrel 62 during the extrusion process, so that the circular shaft 65 drives the sealing plug 66 to open several groups of liquid outlets 64, and at the same time squeezes the reset spring 69, and the material flows unidirectionally from the liquid inlet of the fixed sleeve 61 into the threaded barrel 62 and the liquid outlet 64, and then enters the inner side of the flange tube 1 through the liquid outlet 64, reducing the material between the diaphragm 8 and the notched tube 56, and avoiding waste of excess material when the upper valve shell 7 is opened.
