Description

Technical Field

[0001] The present invention relates to the field of solenoid valves, and further to a spliced solenoid valve module. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control and have a wide range of applications.

[0003] In some applications, multiple solenoid valves and other structures need to be assembled into a valve body to achieve multi-way fluid control. In existing structures, the conventional structure is to stack the solenoid valves and the corresponding valve bodies on the valve seat to achieve multi-way control. However, due to assembly errors, this assembly method inevitably leaves certain gaps between the solenoid valves, resulting in a large solenoid valve module after splicing, which to some extent limits the application of solenoid valves.

[0040] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0041] refer to Figures 1 to 9 The present application provides a spliced solenoid valve module 100 , which includes a first solenoid valve 10 and a second solenoid valve 20 .

[0042] The first solenoid valve 10 includes a first valve body 11 and two first solenoid control bodies 12, which are disposed on opposite sides of the first valve body 11. Specifically, the first valve body 11 has a first side surface 111 and a second side surface 112 opposite to each other, and the two first solenoid valve control bodies 12 are mounted on the first side surface 111 and the second side surface 112, respectively.

[0043] The first valve body 11 has a first valve cavity 13 therein. The first valve body 11 further has a first movable channel 14 communicating with the first valve cavity 13 . The first movable channel 14 has a first movable opening 141 on each of the first side surface 111 and the second side surface 112 .

[0044] The first valve body 11 further comprises a first flow channel 1131, a second flow channel 1132, a third flow channel 1133, and a fourth flow channel 1134, which are in communication with the first valve chamber 13. A first inlet 11310, which is in communication with the first flow channel 1131, and a first outlet 11320, which is in communication with the second flow channel 1132, are provided on the third side surface 113 of the first valve body 11. A first actuating port 11330, which is in communication with the third flow channel 1133, and a second actuating port 11340, which is in communication with the fourth flow channel 1134, are provided on the fourth side surface 114 of the first valve body 11.

[0045] A first valve core can be movably provided in both of the first electromagnetic control bodies 12. The first electromagnetic control body 12 can control the movement of the first valve core, for example, controlling the first valve core to move from the first electromagnetic valve control body 12 into the first valve chamber 13, or controlling the first valve core to move from the first valve chamber 13 into the first electromagnetic control body 12, thereby changing the movement path of the fluid in the first valve chamber 13.

[0046] Specifically, in the first state, the first flow channel 1131 is in communication with the third flow channel 1133, and the second flow channel 1132 is in communication with the fourth flow channel 1134. In the second state, the first flow channel 1131 is in communication with the fourth flow channel 1134, and the second flow channel 1132 is in communication with the third flow channel 1133. Controlling the movement of the first valve core by the first electromagnetic control body 12 enables the first valve body 11 to switch between the first and second states.

[0047] refer to Figure 1 and Figure 9 Furthermore, the first actuation port 11330 and the second actuation port 11340 are adapted to be connected to the first piston 200. The first piston 200 includes a piston cylinder 201 and a piston valve 202. The piston valve 202 is movably mounted within the piston cylinder 201 and divides the piston cylinder 201 into a first movable space 2011 and a second movable space 2012. The first movable space 2011 is in communication with the first actuation port 11330, and the second movable space 2012 is in communication with the second actuation port 11340. In the first state, the first flow channel 1131 is connected to the third flow channel 1133, and the second flow channel 1132 is connected to the fourth flow channel 1134. The liquid in the first actuating port 11330 can enter the first active space 2011 and push the first piston 200 to move toward the second active space 2012, compressing the liquid in the second active space 2012 from the second actuating port 11340 through the fourth flow channel 1134 into the second flow channel 1132 and leave through the first outlet 11320. In the second state, the first flow channel 1131 is connected to the fourth flow channel 1134, and the second flow channel 1132 is connected to the third flow channel 1133. The liquid in the second actuating port 11340 can enter the second active space 2012 and push the first piston 200 to move toward the first active space 2011, compressing the liquid in the first active space 2011 from the first actuating port 11330 through the third flow channel 1133 into the second flow channel 1132 and leave through the first outlet 11320.

[0048] By switching the first valve body 11 between the first and second states, the piston valve 202 of the first piston 200 can be controlled to move back and forth within the piston cylinder 201. The first piston 200 also includes a piston rod 203. One end of the piston rod 203 is connected to the piston valve 202, and the other end extends outside the piston cylinder 201, enabling connection to external equipment. The piston valve 202 can drive the piston rod 203 to move synchronously when moving within the piston cylinder 201.

[0049] refer to Figure 3 and Figure 4 Furthermore, the second solenoid valve 20 includes a second valve body 21 and two second electromagnetic control bodies 22, which are respectively mounted on opposite sides of the second valve body 21. Specifically, one of the second electromagnetic control bodies 22 is mounted on a first surface 211 of the second valve body 21, and the other second electromagnetic control body 22 is mounted on a second surface 212 of the second valve body 21. The first surface 211 and the second surface 212 are respectively located on opposite sides of the second valve body 21.

[0050] The second valve body 21 defines a second valve cavity 23 and a second movable channel 24 therein. The second movable channel 24 communicates with the second valve cavity 23. The first surface 211 and the second surface 212 each define a second movable opening 241 that communicates with the second movable channel 24. The positions of the two second electromagnetic control bodies 22 correspond to the positions of the two second movable openings 241.

[0051] The second valve body 21 has a first channel 2131, a second channel 2132, a third channel 2133, and a fourth channel 2134 in communication with the second valve chamber 23. The third surface 213 of the second valve body 21 has a second inlet 21310 in communication with the first channel 2131, and a second outlet 21320 in communication with the second channel 2132. The fourth surface 214 of the second valve body 21 has a third actuation port 21330 in communication with the third channel 2133, and a fourth actuation port 21340 in communication with the fourth channel 2134.

[0052] A second valve core can be movably provided in both second electromagnetic control bodies 22. The second electromagnetic control body 22 can control the movement of the second valve core, for example, controlling the second valve core to move from the second electromagnetic valve control body 22 into the second valve chamber 23, or controlling the second valve core to move from the second valve chamber 23 into the second electromagnetic control body 22, thereby changing the movement path of the fluid in the second valve chamber 23.

[0053] Specifically, in the third state, the first channel 2131 is in communication with the third channel 2133, and the second channel 2132 is in communication with the fourth channel 2134. In the fourth state, the first channel 2131 is in communication with the fourth channel 2134, and the second channel 2132 is in communication with the third channel 2133. By controlling the movement of the second valve core via the second electromagnetic control body 22, the second valve body 21 can be switched between the third and fourth states.

[0054] refer to Figure 9 Furthermore, the third actuation port 21330 and the fourth actuation port 21340 are adapted to be connected to another first piston 200. By controlling the second valve body 21 to switch between the third state and the fourth state, the piston valve 202 of the first piston 200 can be controlled to move back and forth within the piston cylinder 201.

[0055] The fifth side surface 115 of the first valve body 11, which is opposite the third side surface 113, has a first communication port 11350 and a second communication port 11360. The first valve body 11 also has a first injection channel 11370 that connects the first inlet 11310, the first communication port 11350, and the first valve chamber 13. The first injection channel 11370 also connects to the first flow channel 1131. The first injection channel 11370 also connects to the first outlet 11320, the second communication port 11360, and the first valve chamber 13. The first discharge channel 11380 also connects to the second flow channel 1132. The first valve body 11 and the second valve body 21 are stacked side by side. The fifth side surface 115 of the first valve body 11 is positioned closely against the third surface 213 of the second valve body 21. The first communication port 11350 connects to the second inlet 21310, and the second communication port 11360 connects to the second outlet 21320.

[0056] refer to Figures 1 to 5 In a modified embodiment, the spliced solenoid valve module 100 further includes a first overflow valve 31 and a first interface seat 32, the first overflow valve 31 is installed above the second surface 212 of the second valve body 21, the first interface seat 32 is arranged above the first overflow valve 31, and the first overflow valve 31 is located between the second valve body 21 and the first interface seat 32.

[0057] The third actuation port 21330 and the fourth actuation port 21340 are formed on the surface of the first interface seat 32. There are two second passages 2132 in the second valve body 21, and both second passages 2132 are connected to the second outlet 21320. The spliced solenoid valve module 100 further has two second through-passages 2152. One end of each of the two second through-passages 2152 is connected to the second passages 2132, respectively, and the other end of each second through-passage extends into the first relief valve 31, thereby connecting to the first relief valve 31.

[0058] The spliced solenoid valve module 100 further includes a third through-channel 2153 and a fourth through-channel 2154. The third through-channel 2153 passes through the first interface seat 32, the first relief valve 31, and a portion of the second valve body 21, connecting the third channel 2133 with the third actuating port 21330. The fourth through-channel 2154 passes through the first interface seat 32, the first relief valve 31, and a portion of the second valve body 21, connecting the fourth channel 2134 with the fourth actuating port 21340. Both the third through-channel 2153 and the fourth through-channel 2154 are in communication with the first relief valve 31. Preferably, there are two first overflow valves 31, one first overflow valve 31 is connected to the third through channel 2153 and one second through channel 2152, and the other first overflow valve 31 is connected to the fourth through channel 2154 and another second through channel 2152. The first overflow valve 31 can allow part of the liquid in the third through channel 2153 and the fourth through channel 2154 to flow back to the second outlet 21320 for discharge, rather than moving all of it to the third actuating port 21330 and the fourth actuating port 21340, thereby helping to control the pressure of the liquid discharged from the third actuating port 21330 or the fourth actuating port 21340.

[0059] refer to Figures 1 to 5Furthermore, in the above embodiment, the first solenoid valve 10 forms a first connection, and the second solenoid valve 20, the first relief valve 31, and the first interface seat 32 form a second connection. In a variant embodiment, the spliced solenoid valve module 100 further includes a third connection in addition to the first and second connections. The third connection further includes a third solenoid valve 30, a first hydraulic lock 41, a second relief valve 42, and a second interface seat 43. The third solenoid valve 30 has the same structure as the second solenoid valve 20 and will not be described in detail here. The third solenoid valve 30 and the second solenoid valve 20 are arranged side by side, with the second solenoid valve 20 located between the first and third solenoid valves 10 and 30. Specifically, the third solenoid valve 30 is stacked side by side on the side of the second solenoid valve 20 away from the first solenoid valve 10. The second relief valve 42 is located above the third solenoid valve 30, the first hydraulic lock 41 is located above the second relief valve 42, and the second interface seat 43 is located above the first hydraulic lock 41. That is, the third solenoid valve 30 , the second overflow valve 42 , the first hydraulic lock 41 and the second interface seat 43 are stacked in sequence from bottom to top.

[0060] The fifth surface 215 of the second valve body 21 has a third communication port 2135 and a fourth communication port 2136. The first injection channel 11370 connects the third communication port 2135 with the second inlet 21310, and the first discharge channel 11380 connects the fourth communication port 2136 with the second outlet 21320. Furthermore, the second inlet 21310 of the third solenoid valve 30 connects to the third communication port 2135 of the second solenoid valve 20, and the second outlet 21320 of the third solenoid valve 30 connects to the fourth communication port 2136 of the second solenoid valve 20.

[0061] The third link has two second through-channels 2152a, a third through-channel 2153a, and a fourth through-channel 2154a, which are similar to the two second through-channels 2152, the third through-channel 2153, and the fourth through-channel 2154 of the second link.

[0062] In the third link, one end of the two second through channels 2152 a is communicated with the two second channels 2132 respectively, and the other end both extends into the second overflow valve 42 and is communicated with the second overflow valve 42 .

[0063] The third through-channel 2153a passes through the second interface seat 43, the first hydraulic lock 41, the second relief valve 42, and a portion of the third solenoid valve 30, connecting the third channel 2133 with the third actuating port 21330. The fourth through-channel 2154a passes through the second interface seat 43, the first hydraulic lock 41, the second relief valve 42, and a portion of the third solenoid valve 30, connecting the fourth channel 2134 with the fourth actuating port 21340. The third through-channel 2153a and the fourth through-channel 2154a communicate with the first hydraulic lock 41 and the second relief valve 42, respectively. Preferably, there are also two second relief valves 42, with the same structure and function as the two first relief valves 31, and their details are omitted here. During operation, when the first piston 200 corresponding to the third link moves to a suitable state, closing the first hydraulic lock 41 can prevent the liquid in the first active space 2011 and the second active space 2012 of the piston cylinder 201 from flowing back into the second channel 2132, thereby enabling the first piston 200 to remain in a stationary state.

[0064] refer to Figures 1 to 5 Furthermore, based on the above embodiment, the spliced solenoid valve module 100 further includes a fourth unit, which includes a fourth solenoid valve 40, a third overflow valve 51, a second hydraulic lock 52, a first pressure reducing valve 53, and a third interface seat 54. The structure of the fourth solenoid valve 40 is the same as that of the second solenoid valve 20 and will not be repeated here. The fourth solenoid valve 40 is arranged side by side with the third solenoid valve 30, and the third solenoid valve 30 is located between the second solenoid valve 20 and the fourth solenoid valve 40, that is, the fourth solenoid valve 40 is arranged side by side on the side of the third solenoid valve 30 away from the second solenoid valve 20, and the second inlet 21310 of the fourth solenoid valve 40 is connected to the third communication port 2135 of the third solenoid valve 30, and the second outlet 21320 of the fourth solenoid valve 40 is connected to the fourth communication port 2136 of the third solenoid valve 30. The third relief valve 51 is disposed above the fourth solenoid valve 40, the first pressure reducing valve 53 is disposed above the third relief valve 51, the second hydraulic lock 52 is disposed above the first pressure reducing valve 53, and the third interface seat 54 is disposed above the second hydraulic lock 52. In other words, the fourth solenoid valve 40, the third relief valve 51, the first pressure reducing valve 53, the second hydraulic lock 52, and the third interface seat 54 are stacked in order from bottom to top.
