Description

Technical Field

[0001] This invention relates to the field of solenoid valves, and more particularly to a modular solenoid valve module. Background Technology

[0002] Solenoid valves are electromagnetically controlled industrial devices and are fundamental components of automation used to control fluids. They are used in industrial control systems to adjust the direction, flow rate, 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-channel fluid control. In existing structures, the conventional approach is to stack the solenoid valves and their associated valve bodies on a valve seat to achieve multi-channel control. However, due to assembly errors, this method inevitably results in gaps between the solenoid valves, leading to a larger overall size of the assembled solenoid valve module, which to some extent limits its application.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] refer to Figures 1 to 9 This application provides a modular 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 opposite first side 111 and second side 112, and the two first solenoid valve control bodies 12 are respectively mounted on the first side 111 and the second side 112.

[0043] The first valve body 11 has a first valve cavity 13, and the first valve body 11 also 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 the first side 111 and the second side 112.

[0044] The first valve body 11 further includes a first flow channel 1131, a second flow channel 1132, a third flow channel 1133, and a fourth flow channel 1134 communicating with the first valve cavity 13. The third side 113 of the first valve body 11 has a first inlet 11310 communicating with the first flow channel 1131 and a first outlet 11320 communicating with the second flow channel 1132. The fourth side 114 of the first valve body 11 has a first actuation port 11330 communicating with the third flow channel 1133 and a second actuation port 11340 communicating with the fourth flow channel 1134.

[0045] Each of the two first electromagnetic control bodies 12 is movably provided with a first valve core. The first electromagnetic control body 12 can control the movement of the first valve core, such as 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 connected to the third flow channel 1133, and the second flow channel 1132 is connected to the fourth flow channel 1134. 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. By controlling the movement of the first valve core through the first electromagnetic control body 12, the first valve body 11 can be switched between the first state and the second state.

[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 installed in the piston cylinder 201 and divides the piston cylinder 201 into a first active space 2011 and a second active space 2012. The first active space 2011 communicates with the first actuation port 11330, and the second active space 2012 communicates 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 actuation port 11330 can enter the first active space 2011 and push the first piston 200 to move towards the second active space 2012, compressing the liquid in the second active space 2012 to enter the second flow channel 1132 through the second actuation port 11340 via the fourth flow channel 1134, and exit 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 actuation port 11340 can enter the second active space 2012 and push the first piston 200 to move towards the first active space 2011, compressing the liquid in the first active space 2011 to enter the second flow channel 1132 from the first actuation port 11330 through the third flow channel 1133, and exit through the first outlet 11320.

[0048] By controlling the first valve body 11 to switch between the first state and the second state, 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 which is connected to the piston valve 202, and the other end extends to the outside of the piston cylinder 201, allowing connection to external equipment. When the piston valve 202 moves within the piston cylinder 201, it can drive the piston rod 203 to move synchronously.

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

[0050] The second valve body 21 has a second valve cavity 23 and a second movable channel 24, which communicates with the second valve cavity 23. Each of the first surface 211 and the second surface 212 has 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 communicating with the second valve cavity 23. The third surface 213 of the second valve body 21 has a second inlet 21310 communicating with the first channel 2131 and a second outlet 21320 communicating with the second channel 2132. The fourth surface 214 of the second valve body 21 has a third actuation port 21330 communicating with the third channel 2133 and a fourth actuation port 21340 communicating with the fourth channel 2134.

[0052] Each of the two second electromagnetic control bodies 22 is movably provided with a second valve core. The second electromagnetic control body 22 can control the movement of the second valve core, such as 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 connected to the third channel 2133, and the second channel 2132 is connected to the fourth channel 2134. In the fourth state, the first channel 2131 is connected to the fourth channel 2134, and the second channel 2132 is connected to the third channel 2133. By controlling the movement of the second valve core through 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 of the first pistons 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 115 of the first valve body 11, opposite to the third side 113, has a first connecting port 11350 and a second connecting port 11360. The first valve body 11 also has a first injection channel 11370 connecting the first inlet 11310, the first connecting port 11350, and the first valve cavity 13, and the first injection channel 11370 is also connected to the first flow channel 1131; and a first discharge channel 11380 connecting the first outlet 11320, the second connecting port 11360, and the first valve cavity 13, and the first discharge channel 11380 is also connected 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 115 of the first valve body 11 is closely attached to the third surface 213 of the second valve body 21, and the first connecting port 11350 is connected to the second inlet 21310, and the second connecting port 11360 is connected to the second outlet 21320.

[0056] refer to Figures 1 to 5 In a modified embodiment, the modular solenoid valve module 100 further includes a first overflow valve 31 and a first interface seat 32. The first overflow valve 31 is mounted above the second surface 212 of the second valve body 21, and the first interface seat 32 is disposed above the first overflow valve 31. 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. The second valve body 21 contains two second channels 2132, and both second channels 2132 communicate with the second outlet 21320. The modular solenoid valve module 100 further has two second through channels 2152, one end of which communicates with the two second channels 2132 respectively, and the other end of each extends into the first overflow valve 31 and communicates with the first overflow valve 31.

[0058] The modular 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 overflow valve 31, and a portion of the second valve body 21, connecting the third channel 2133 to the third actuation port 21330. The fourth through channel 2154 passes through the first interface seat 32, the first overflow valve 31, and a portion of the second valve body 21, connecting the fourth channel 2134 to the fourth actuation port 21340. Both the third through channel 2153 and the fourth through channel 2154 are connected to the first overflow valve 31. Preferably, there are two first overflow valves 31. One first overflow valve 31 connects the third through channel 2153 and a second through channel 2152, and the other first overflow valve 31 connects the fourth through channel 2154 and another second through channel 2152. The first overflow valve 31 allows some 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, instead of all of it moving to the third actuation port 21330 and the fourth actuation port 21340, thereby helping to control the pressure of the liquid discharged from the third actuation port 21330 or the fourth actuation port 21340.

[0059] refer to Figures 1 to 5Further, in the above embodiments, the first solenoid valve 10 forms a first section, and the second solenoid valve 20, the first relief valve 31, and the first interface seat 32 form a second section. In a modified embodiment, the spliced ​​solenoid valve module 100 further includes a third section based on the above first and second sections. In the third section, the spliced ​​solenoid valve module 100 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 again here. The third solenoid valve 30 and the second solenoid valve 20 are arranged side by side and attached together, with the second solenoid valve 20 located between the first solenoid valve 10 and the third solenoid valve 30, that is, 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. In other words, the third solenoid valve 30, the second overflow valve 42, the first hydraulic lock 41, and the second interface seat 43 are stacked sequentially 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 and the second inlet 21310, and the first discharge channel 11380 connects the fourth communication port 2136 and the second outlet 21320. Furthermore, the second inlet 21310 of the third solenoid valve 30 is connected to the third communication port 2135 of the second solenoid valve 20, and the second outlet 21320 of the third solenoid valve 30 is connected to the fourth communication port 2136 of the second solenoid valve 20.

[0061] The third section has two second through channels 2152a, third through channel 2153a, and fourth through channel 2154a that are similar to the two second through channels 2152, the third through channel 2153, and the fourth through channel 2154 in the second section.

[0062] In the third section, one end of each of the two second through channels 2152a is connected to the two second channels 2132, and the other end of each extends into the second overflow valve 42 and is connected to 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 part of the third solenoid valve 30, connecting the third channel 2133 to the third actuation 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 part of the third solenoid valve 30, connecting the fourth channel 2134 to the fourth actuation port 21340. Furthermore, the third through channel 2153a and the fourth through channel 2154a are respectively connected to the first hydraulic lock 41 and the second relief valve 42. Preferably, there are also two second relief valves 42, with the same structure and function as the two first relief valves 31, which will not be described further here. During operation, when the first piston 200 corresponding to the third section 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, thus keeping the first piston 200 stationary.

[0064] refer to Figures 1 to 5 Furthermore, based on the above embodiments, the modular solenoid valve module 100 further includes a fourth section, which includes a fourth solenoid valve 40, a third relief 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 described again here. The fourth solenoid valve 40 and the third solenoid valve 30 are arranged side by side and attached together. 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 positioned above the fourth solenoid valve 40, the first pressure reducing valve 53 is positioned above the third relief valve 51, the second hydraulic lock 52 is positioned above the first pressure reducing valve 53, and the third interface seat 54 is positioned 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 arranged in a stacked manner from bottom to top.

[0065] The fourth section has a first through channel 2151b, two second through channels 2152b, a third through channel 2153b, and a fourth through channel 2154b, which are similar to the two second through channels 2152, the third through channel 2153, and the fourth through channel 2154 in the second section.
