[0034] As Figures 1 to 9 shown, the embodiment of the present invention patent provides an agglomerated multi-channel valve, including: a valve mounting part 100, a plurality of annular valve parts 200 circumferentially arranged around the valve mounting part 100, and a flow pipeline 300 arranged inside the valve mounting part 100. Among them, the valve mounting part 100 is the installation base of the whole device, and the valve mounting part 100 is suitable for carrying a plurality of annular valve parts 200; the plurality of annular valve parts 200 are coaxially arranged, and the annular valve part 200 is suitable for guiding the medicinal liquid to be shunted through different channels by opening and closing the corresponding channels; the flow pipeline 300 is fixedly connected inside the valve mounting part 100, and the flow pipeline 300 can be communicated with each annular valve part 200 to realize the shunting of the medicinal liquid to the corresponding pipeline. For the above components, detailed descriptions will be given one by one below.

[0035] Valve mounting part

[0036] The valve mounting part 100 serves as the installation base for the entire device. There is a liquid inlet 130 and a liquid outlet on the valve mounting part 100. The liquid inlet 130 and the liquid outlet are respectively located in the middle of the two end faces of the valve mounting part 100. The liquid medicine can enter the interior of the valve mounting part 100 through the liquid inlet 130 and be divided. The valve mounting part 100 specifically includes: a valve seat platform 110 and two side connection parts 120 fixed to the upper and lower end faces of the valve seat platform 100. Among them, the valve seat platform 110 is suitable for carrying the annular valve part 200; the side connection part 120 is suitable for carrying the valve seat platform 100 and positioning the flow-through head, and divides the two end faces of the valve seat platform 110 into several regions, thereby enhancing and forming a multi-channel valve.

[0037] The cross-section of the valve seat platform 110 is polygonal. Specifically, in this embodiment, the outer wall of the cross-section of the valve seat platform 110 is a regular decagon, and the valve seat platform 110 is provided with a round hole penetrating the upper and lower end faces. The round hole is coaxially arranged with the inscribed circle corresponding to the regular decagon of the outer wall of the valve seat platform 110. The side wall of the valve seat platform 110 is suitable for carrying a number of on-off valves 210.

[0038] The following specifically describes the composition of the valve seat platform 110. The valve seat platform 110 includes: a number of fitting end faces 111 opened on the side wall of the valve seat platform 110, a circular ring platform 112 opened in the inner circle of the valve seat platform 110, a number of rows of penetrating holes 113 opened on each of the fitting end faces 111, and a number of positioning holes 114 opened on the end face of the circular ring platform 112. One fitting end face 111 corresponds to one side wall of the valve seat platform 110. Two penetrating holes 113 are opened in the center of one fitting end face 111 along the height direction. One penetrating hole 113 corresponds to one annular valve part 200; the circular ring platform 112 is opened in the inner circle of the valve seat platform 110. The circular ring platform 112 is coaxially arranged with the round hole opened on the valve seat platform 110, and the radius of the circular ring platform 112 is greater than the radius of the round hole; in this embodiment, the preferred number of the positioning holes 114 is five, and the center connection lines of the five positioning holes 114 on the same horizontal plane form a regular pentagon.

[0039] The side connection parts 120 are arranged on the two end faces of the valve seat platform 110. Specifically, there are two side connection parts 120, and they can be respectively fixedly connected to the circular ring platforms 112 opened on the two end faces of the valve seat platform 110. At the same time, the two side connection parts 120 can also be kept relatively fixedly connected. The side connection part 120 is suitable for carrying the valve seat platform 110 and positioning the flow-through head, and divides the two end faces of the valve seat platform 110 into several regions. When the liquid in the valve body flows into the valve seat platform 110, it can flow out from the pipelines divided on the corresponding side connection parts 120, thereby enhancing and forming a multi-channel valve.

[0040] The structure of the side connection part 120 will be specifically described below. The connection part 120 includes an inner core ring 121, a clamping petal 122 arranged on the outer side of the inner core ring 121, an installation station 123 formed between two adjacent clamping petals 122, a positioning waist-shaped hole 124 arranged at intervals on the clamping petal 122, an annular edge 125 opened at the lower edge of the positioning waist-shaped hole 124, an arc-shaped facing 126 arranged on the end face of the clamping petal 122, a tip head 127 formed at the tip of two adjacent clamping petals 122, and a plurality of positioning connection holes 128 opened on the inner core ring 121.Among them, the inner core ring 121 is located in the middle of the side connection part 120. The thicknesses of the inner core ring 121 and the clamping petals 122 are equal to the distance from the circular truncated cone 102 to the end face of the corresponding valve seat platform 100, and the inner core ring 121 can serve as the positioning reference for the clamping petals 122. There are ten clamping petals 122, and the clamping petals 122 are arranged around the inner core ring 121. The clamping petals 122 can be attached to the side wall of the circular truncated cone 102. Specifically, the maximum distance from the center of the inner circle of the inner core ring 121 to each clamping petal 122 is equal to the distance from the axis of the valve seat platform 100 to the side wall of the circular truncated cone 102. The side connection part 120 can be placed into the circular truncated cone 102 along the height direction. An installation station 123 is formed by the gap between two adjacent clamping petals 122. Since each clamping petal 122 is evenly arranged along the circumferential direction of the inner core ring 121, the angles between two clamping petals 122 are equal. As a result, the sizes and shapes of all installation stations 123 are the same and are also evenly arranged along the circumferential direction of the inner core ring 121, thus ensuring that the distance from the central axis of the side connection part 120 to any installation station 123 is equal, and the distance from the central axis of the side connection part 120 to the edge of any valve seat platform 100 is equal. In addition, when the side connection part 120 is installed on the circular truncated cone 102, the fitting end face 101 of each valve seat platform 100 corresponds to an installation station 123. The positioning waist-shaped holes 124 are respectively arranged at intervals on one clamping petal 122. One positioning waist-shaped hole 124 corresponds to one positioning hole 104. The widths of the two radial sides of the positioning waist-shaped hole 124 are larger. The lower edge of the positioning waist-shaped hole 124 has an annular edge 125. By selecting a suitable stud, it can be threadedly connected to the positioning waist-shaped hole 124 and the positioning hole 104 in sequence. After the connection is completed and the connection part 120 is rotated, the stud can slide along the positioning waist-shaped hole 124. The clamping petals 122 are opened at the outer ends of the clamping petals 122. The clamping petals 122 can be attached to the inner wall of the circular truncated cone 102 through the arc-shaped contact surface 126, and it can prevent the clamping petals 122 from scratching the inner wall of the circular truncated cone 102 when rotating. A pair of tip heads 127 are formed by the tips of two adjacent clamping petals 122, and the angle between the tip heads 127 is equal to the outer angle formed by the two side walls of the hexagonal nut. When the hexagonal nut is placed in the installation station 123 and slides inward, the two side walls of the hexagonal nut can be attached to the two side walls of the tip heads 127. The connection holes 128 are opened in the inner core ring 121, and the connection holes 128 can connect the two side connection parts 120. Specifically, after the two side connection parts 120 are installed into the circular truncated cone 102, by selecting a number of suitable bolts and passing them through the corresponding connection holes 128 on the two side connection parts 120 in sequence, the two side connection parts 120 can be fixedly connected.

[0041] Flow pipeline

[0042] The flow pipe 300 is arranged inside the valve seat platform 100, and the cross-section of the flow pipe 300 is a regular decagon corresponding to the valve seat platform 110. A number of cross-flow ports 310 are formed on the side wall of the flow pipe 300, and the cross-flow ports 310 correspond to the through holes 113. One cross-flow port 310 is coaxially arranged with one through hole 113. The flow pipe 300 can be fixedly connected to the side connection part 120 through the circular holes circumferentially arranged at the upper and lower end faces. At the same time, since the side connection part 120 is fixedly connected to the valve seat platform 110, the flow pipe 300 is fixedly connected to the valve seat platform 110. At the same time, a through hole is formed in the middle of the upper and lower end faces of the flow pipe 300, and the liquid inlet 130 and the liquid outlet are connected at both ends through the through hole.

[0043] Annular valve part

[0044] The annular valve part 200 has a water inlet, and the water inlet is located on the flow pipe 300 between the liquid inlet 130 and the liquid outlet and is arranged around the side wall of the valve support part 100. Specifically, one annular valve part 200 corresponds to one through hole 113 formed in the side wall of the valve support part 100. One annular valve part 200 has a switching cylinder 212, and the piston rod of the switching cylinder 212 can pass through the through hole 113 from the outside of the valve support part 100.

[0045] The annular valve part 200 includes a number of on-off valves 210. The on-off valves 210 abut against the fitting end face 111, and the end parts are connected and communicated with the flow pipe 300. An outlet is arranged at the installation station 123 corresponding to the fitting end face 111.

[0046] The structure of the on-off valve 210 will be specifically described below. The on-off valve 210 specifically includes: an L-shaped pipe 211, a switching cylinder 212, and a valve core rod 213 fixed to the end part of the piston rod of the switching cylinder 212. One end of the L-shaped pipe 211 is clamped at the installation station 123, and the waist of the L-shaped pipe 211 is connected and communicated with the cross-flow port 310, so as to guide the liquid medicine of the corresponding component to flow in. The piston rod of the switching cylinder 212 can pass through the through hole 113. In addition, the valve core rod 213 can also stretch and contract along with the piston rod of the switching cylinder 212. The valve core rod 213 passes through the L-shaped pipe 211 and can open and close the L-shaped pipe 211, so as to ensure that the L-shaped pipe 211 is only in the open state when the corresponding liquid medicine needs to be separated, and is in the closed state when other medicines are separated, reducing the mixing of liquid medicines to a certain extent. In addition, the side wall of the valve core rod 213 abuts against and closes the cross-flow port 310, so as to prevent the liquid medicine from flowing in through the gap between the side wall of the valve core rod 213 and the cross-flow port 310 during the shunting process, further reducing the mixing of liquid medicines to a certain extent.

[0047] The structure of the L-shaped pipe 211 will be specifically described below. The L-shaped pipe 211 specifically includes: a positioning sleeve 2111 fixed in the cross-flow port 310, a sealing ring outer sleeve 2112 fixedly connected to the positioning sleeve 2111, and a liquid inlet joint 2113 fixed on the side wall of the sealing ring outer sleeve 2112. The positioning sleeve 2111 is coaxially arranged with the valve core rod 213, and the inner wall is suitable for the flow of liquid medicine. A liquid inlet through-port is provided on the side wall of the sealing ring outer sleeve 2112, and the end of the sealing ring outer sleeve 2112 is connected and communicated with the cross-flow port 310. The valve core rod 213 sequentially passes through the positioning sleeve 2111, the sealing ring outer sleeve 2112, and the cross-flow port 310. The liquid inlet joint 2113 is communicated with the liquid inlet through-port. When the liquid medicine enters from the liquid inlet 130, the corresponding L-shaped pipe 211 is opened through the corresponding valve core rod 213, and the other valve core rods 213 close the corresponding L-shaped pipes 211, so that the liquid medicine can be divided and flows out from the only liquid inlet joint 2113.

[0048] To ensure the reliability of the sealing ring outer sleeve 2112, a first sealing cap 2114 is fixed at the joint of the sealing ring outer sleeve 2112 and the positioning sleeve 2111; a second sealing cap 2115 is fixed at the joint of the sealing ring outer sleeve 2112 and the cross-flow port 310, and piston sealing rings 2116 are fixed on the inner walls of the ports of the two sealing ring outer sleeves 2112. The piston sealing rings 2116 are in contact with the side wall of the valve core rod 213. The first sealing cap 2114 and the second sealing cap 2115 can respectively seal the sealing ring outer sleeve 2112 from the outside, and the piston sealing rings 2116 can seal the sealing ring outer sleeve 2112 from the inside.

[0049] To guide the valve core rod 213 to plug the cross-flow port 310 in the correct direction after passing through the L-shaped pipe 211, there is also a step in the cross-flow port 310, and a valve core guide sleeve 2117 is fixed at the step. When the valve core rod 213 extends out of the L-shaped pipe 211, it can extend into and plug the cross-flow port 310 along the valve core guide sleeve 2117.

[0050] To facilitate the fixing of the on-off cylinder 212 on the fitting end face 111, a plurality of cylinder backing plates 400 are also fixed on the fitting end face 111. The on-off cylinder 212 is fixed on the cylinder backing plates 400, and the valve core rod 213 sequentially passes through the cylinder backing plates 400, the through-hole 113, and the cross-flow port 310.

[0051] This kind of aggregated multi-channel valve provides a good liquid inlet and outlet channel for traditional Chinese medicine liquid through the setting of the valve mounting part; through the setting of the annular valve part, it is convenient to form a better flow splitting condition to disperse the liquid from the valve mounting part circumferentially.
