[0034] It should be noted that in this embodiment, the direction of X in the accompanying drawings is defined as the first direction, the direction of Y is defined as the second direction, and the direction of Z is defined as the third direction, and the first direction, the second direction, and the third direction are perpendicular to each other.
[0035] Please refer to Figures 1 to 4 , to achieve the above object, the present invention provides a fluid valve, including a container seat 100, pipe joints, and solenoid valves.
[0036] A channel for fluid flow is provided inside the container seat 100.
[0037] The pipe joint is installed on the assembly seat 100, including a first joint 210, a second joint 220, a third joint 230 and a fourth joint 240 connected to the channel, at least one of the first joint 210, the second joint 220, the third joint 230 and the fourth joint 240 is used for fluid to flow into the channel and at least one is used for fluid to flow out of the channel.
[0038] The channel includes a first channel, a second channel, a third channel and a fourth channel which are connected to each other, and the first channel is connected to the first joint 210 , the second channel is connected to the second joint 220 , the third channel is connected to the third joint 230 , and the fourth channel is connected to the fourth joint 240 .
[0039] The solenoid valve is installed on the assembly seat 100 , and includes a first solenoid valve 310 for opening and closing the first connector 210 , a second solenoid valve 320 for opening and closing the second connector 220 , and a third solenoid valve 330 for opening and closing the third connector 230 .
[0040] The assembly seat 100 is a cubic structure, and has two grooves formed by inward depression on both sides of the assembly seat 100 in the first direction. The two grooves each include a mounting surface 110 perpendicular to the first direction. The second solenoid valve 320 is installed on one mounting surface 110, and the third solenoid valve 330 is installed on the other mounting surface 110.
[0041] The first solenoid valve 310 is used for opening and closing the first connector 210, the second solenoid valve 320 is used for opening and closing the second connector 220, and the third solenoid valve 330 is used for opening and closing the third connector 230, so that the first connector 210, the second connector 220, the third connector 230 and the fourth connector 240 can be used for mixing three fluids and then flowing out along one connector and three kinds of diversions of one fluid. The second solenoid valve 320 and the third solenoid valve 330 are installed in two grooves formed by the inward depression of the assembly seat 100, which can make the entire fluid valve structure compact and save space. At the same time, the second solenoid valve 320 and the third solenoid valve 330 are arranged relative to each other, so that the reaction time error of the solenoid valve is small, so that the flow rate and flow velocity of the fluid along the second connector 220 and the third connector 230 are the same, and can be evenly distributed or mixed.
[0042] The first solenoid valve 310, the second solenoid valve 320 and the third solenoid valve 330 are all installed at different positions of the assembly seat 100 through the fixing member 340. The fixing member 340 can be set at the diagonal side of the first solenoid valve 310, the second solenoid valve 320 and the third solenoid valve 330 away from the assembly seat 100 to ensure the stable connection of the first solenoid valve 310, the second solenoid valve 320 and the third solenoid valve 330.
[0043] The first solenoid valve 310, the second solenoid valve 320, and the third solenoid valve 330 each include a coil 311 and a valve core 312. A guide tube for the directional movement of the valve core 312 to control the on / off of the fluid is provided inside the coil 311. When the first solenoid valve 310, the second solenoid valve 320, and the third solenoid valve 330 are normally closed solenoid valves, the coil 311 and the valve core 312 are in a conducting state when they are attracted to each other and in an open state when they are disconnected. When it is in the open state, the fluid cannot flow through.
[0044] The first solenoid valve 310, the second solenoid valve 320, and the third solenoid valve 330 further include connection wires connected to the coil 311. The connection wires on the second solenoid valve 320 and the third solenoid valve 330 extend along the third direction, and the connection wire on the first solenoid valve 310 extends along the first direction, so as to reduce the space occupied by the fluid valve with connection wires and facilitate the docking of the connection wires with external wires after the subsequent fluid valves are installed.
[0045] The second channel and the third channel are coaxially arranged and extend along the first direction, and the first channel extends along the second direction, so that the first channel, the second channel, and the third channel are arranged in a T shape.
[0046] Symmetrically arranged through two mounting surfaces 110 and coaxially arranged the second channel and the third channel, so that the second solenoid valve 320 as a whole with the second channel it controls and the third solenoid valve 330 as a whole with the third channel it controls are symmetrically designed, resulting in a small reaction time error between the second solenoid valve 320 and the third solenoid valve 330, and the same fluid flow rate and flow volume, which can be evenly distributed or mixed.
[0047] In this embodiment, the first joint 210, the second joint 220, and the third joint 230 are all fluid inlets, and the fourth joint 240 is a fluid outlet. By controlling the on / off of the first solenoid valve 310 for the first joint 210, the on / off of the second solenoid valve 320 for the second joint 220, and the on / off of the third solenoid valve 330 for the third joint 230, three fluids are mixed, and finally the mixed fluid flows out through the fourth joint 240 together.
[0048] Among them, by controlling the opening and closing moments and durations of each solenoid valve, the three fluids can be mixed in proportion.
[0049] In some embodiments, the fourth joint 240 is a fluid inlet, and the first joint 210, the second joint 220, and the third joint 230 are all fluid outlets. By controlling the on / off of the first solenoid valve 310 for the first joint 210, the on / off of the second solenoid valve 320 for the second joint 220, and the on / off of the third solenoid valve 330 for the third joint 230, the fluid flowing in through the fourth joint 240 can be distributed and flow out along the first joint 210, the second joint 220, and the third joint 230.
[0050] Among them, by controlling the opening and closing time and duration of each solenoid valve, the proportional distribution of the fluid can be achieved.
[0051] In addition, when the first joint 210, the second joint 220, and the third joint 230 are all fluid inlets, and the fourth joint 240 is a fluid outlet, by controlling the opening and closing of the passage of the first solenoid valve 310 for the first joint 210, the second solenoid valve 320 for the second joint 220, and the third solenoid valve 330 for the third joint 230, the three fluids can flow out through the fourth joint 240 respectively. If it is necessary to switch two fluids with different physical and chemical properties and clean the inside of the valve seat and the pipeline before each switch, then one of the two fluids needs to be connected to the second joint 220, and the other is connected to the third joint 230. The first joint 210 is connected with a cleaning device, and the cleaning liquid of the cleaning device can flow into the channel along the first joint 210 and flow out along the fourth joint 240.
[0052] For example, when the fluid entering from the second joint 220 needs to be switched to the fluid entering from the third joint 230, first, the cleaning liquid of the first joint 210 is continuously cleaned through the fourth joint 240 by the first solenoid valve 310, and then the other fluid is switched after the cleaning is completed; when the fluid entering from the third joint 230 needs to be switched to the fluid entering from the second joint 220, similarly, first, the cleaning liquid of the first joint 210 is continuously cleaned through the fourth joint 240 by the first solenoid valve 310, and then the other fluid is switched after the cleaning is completed.
[0053] It should be noted that the internal fluid channels of the manifold block 100 are compact, with small dead zones during cleaning and washing, no dead corners and no residues during cleaning, fast cleaning speed, the second channel and the third channel are coaxially arranged, and the first channel, the second channel, and the third channel are arranged in a T-shape, so that when the first joint 210 is connected with a cleaning device to clean the channel, the cleaning efficiency is the highest and the cleaning effect is the best.
[0054] The manifold block 100 further includes two side surfaces 120 and a bottom surface 130 connecting the two mounting surfaces 110. The two side surfaces 120 are located on both sides of the manifold block 100 in the second direction, the bottom surface 130 is located on one side of the manifold block 100 in the third direction, the second joint 220 is installed on one side surface 120, the third joint 230 is installed on the other side surface 120, and the fourth joint 240 is installed on the bottom surface 130.
[0055] The cross-section of the container mounting base 100 perpendicular to the second direction is T-shaped. The container mounting base 100 includes a connected "I"-shaped structure and a "-" -shaped structure. By arranging a second solenoid valve 320 and a third solenoid valve 330 on the left and right sides of the "I"-shaped structure below the "-" -shaped structure, arranging a second joint 220 and a third joint 230 in the front and back of the "I"-shaped structure, and arranging a fourth joint 240 at the bottom of the "I"-shaped structure facing away from the "-" -shaped structure, the container mounting base 100 can have a compact shape, small occupied space, and high space utilization rate.
[0056] The container mounting base 100 further includes a top surface 140 facing away from the bottom surface 130 and two end surfaces 150 parallel to the mounting surface 110. The first solenoid valve 310 is installed on the top surface 140, and the first joint 210 is installed on one end surface 150.
[0057] The top surface 140 is the plane of the "-" -shaped structure facing away from the "I"-shaped structure, and the end surfaces 150 are the left and right side planes of the "-" -shaped structure. By installing the first solenoid valve 310 on the top surface 140 and the first joint 210 on one end surface 150, the container mounting base 100 can be made more compact. Three joints can be added to the other end surface 150 where the first joint 210 is not provided, and the front and back sides of the "-" -shaped structure according to the actual situation, and corresponding solenoid valves are set to control the on-off of the joints, so as to be applicable to more usage requirements and application scenarios.
[0058] In addition, the corners of the container mounting base 100 can be set as inclined surfaces or arc surfaces to save materials while providing an avoidance space for installation. The container mounting base 100 can select materials according to actual needs, such as POM, PEEK, nylon, stainless steel 304, stainless steel 316, etc.

[0061] Specific examples are used in this article to elaborate on the principles and implementation manners of the present invention.
