Description

Technical Field

[0001] The utility model belongs to the technical field of fluid transportation, and in particular relates to a three-tube pinch valve. Background Art

[0002] The pinch valve uses pneumatic, electric, manual or hydraulic drive to squeeze the sleeve to achieve the switching / regulating function. The sleeve (hose) is the most important part of the pinch valve, providing corrosion resistance, wear resistance and pressure bearing capacity. The pinch valve controls the on-off by squeezing or loosening the hose. The medium only passes through the hose, and other parts of the valve body do not contact the medium. This means that compared with other types of solenoid valves, the pinch valve can pass medium with particles without clogging.

[0003] The current pinch valve is suitable for single-pipe circulation. However, in the process of making milk tea, it is often necessary to control the inflow of multiple ingredients (such as tea base, creamer, and syrup) at the same time. Therefore, this pinch valve is incapable of handling when there are many ingredients. If multiple pinch valves are used, the production cost will be increased in disguise. Therefore, a three-tube pinch valve is proposed. Utility Model Content

[0009] Furthermore, the upper notch and the lower notch are respectively on the same horizontal plane as the No. 2 pipe and the No. 3 pipe.

[0010] Furthermore, the side edges of the cross-interference member are arc-shaped.

[0011] Furthermore, the rotating shaft is movably connected to the upper and lower sides of the shell through a No. 1 bearing and a No. 2 bearing respectively.

[0012] Furthermore, a driving motor and a gear transmission group are installed on the top of the shell, and the top end of the rotating shaft extends into the gear transmission group housing and is connected to the gear transmission group.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the embodiments.

[0025] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0026] See also Figure 1-4 The utility model provides a three-tube clamp valve, including a housing 10; cover plates 110 are installed on both sides of the housing 10 by bolts, and the two cover plates 110 are provided with a first installation groove 1101 and a second installation groove 1102, and the first installation groove 1101 and the second installation groove 1102 are in the same horizontal plane, and the first tube 310 and the second tube 320 are installed on the two cover plates 110, and the left and right ends of the first tube 310 and the second tube 320 are respectively arranged on the first installation groove 1101 and the second installation groove 1102; a third installation groove 1103 is arranged on the right side of the housing 10, and a third tube 330 is radially arranged in the third installation groove 1103. The horizontal plane where the third tube 330 is located is lower than the horizontal plane where the first tube 310 and the second tube 320 are located, so as to prevent the third tube 330 from hindering the first tube 310 and the second tube 320 from extending out.

[0027] The first pipe 310 , the second pipe 320 , and the third pipe 330 are all made of elastic material.

[0028] See also Figure 1-4 Four mounting columns 120 are installed on the top of the housing 10 by bolts, and the four mounting columns 120 can be used to install the three-tube clamp valve at a suitable position by bolts.

[0029] A driving motor 130 and a gear transmission group are installed on the top of the shell 10. The gear transmission group can be set up using the existing two gears in a horizontal and vertical meshing connection mode. The gear transmission group is installed in the gear transmission group housing 140. The driving motor 130 and the gear transmission group are arranged horizontally, which can reduce the vertical height of the three-tube clamp valve and facilitate the installation of four mounting columns 120.

[0030] See also Figure 1-5 A rotating shaft 210 is provided inside the housing 10, and the rotating shaft 210 is movably sleeved with the upper and lower sides of the housing 10 through a No. 1 bearing 211 and a No. 2 bearing 212 respectively. The top of the rotating shaft 210 extends into the gear transmission group housing 140, and the rotating shaft 210 is connected to the gear transmission group; a groove 2101 is provided on one side of the rotating shaft 210, and a cross-interference piece 220 is sleeved on the rotating shaft 210, and a thread groove 2201 is provided on the cross-interference piece 220, and a fixing bolt 221 is threadedly sleeved on the thread groove 2201, and the end of the fixing bolt 221 is in contact with the groove 2101 on the rotating shaft 210, so that the cross-interference piece 220 can rotate with the rotation of the rotating shaft 210;

[0031] An upper notch 2202 and a lower notch 2203 are provided on a protrusion on one side of the cross-interference piece 220. The upper notch 2202 and the lower notch 2203 are respectively on the same horizontal plane with the No. 2 pipe 320 and the No. 3 pipe 330. The gap between the side of the cross-interference piece 220 and the inner wall of the shell 10 and the cover plate 110 is small. If the gap is too large, the side of the cross-interference piece 220 and the inner wall of the shell 10 and the cover plate 110 will not be able to clamp the No. 1 pipe 310, the No. 2 pipe 320, and the No. 3 pipe 330.

[0032] The side edges of the cross-contact piece 220 are arc-shaped, which can reduce the friction between the cross-contact piece 220 and the pipeline.

[0033] The working principle and use process of this utility model: see Figure 3 , the third tube 330 flows; the lower notch 2203 is aligned with the third tube 330, and the other side edges of the cross-interference member 220 without notches clamp the first tube 310 and the second tube 320 through the inner wall of the shell 10, so that the first tube 310 and the second tube 320 cannot flow.

[0034] When the No. 1 pipe 310 or the No. 2 pipe 320 needs to circulate, the rotating shaft 210 is driven to rotate by the driving motor 130 and the gear transmission group. The rotating shaft 210 drives the cross-interference member 220 to rotate 90 degrees, so that the upper notch 2202 is aligned with the No. 1 pipe 310. At this time, the other side edges of the cross-interference member 220 without notches clamp the No. 2 pipe 320 and the No. 3 pipe 330 through the inner wall of the shell 10 and the inner wall of the cover plate 110, so that the No. 2 pipe 320 and the No. 3 pipe 330 cannot circulate; the same operation can allow the No. 2 pipe 320 to circulate.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
