Problems solved by technology
[0002] At present, there will be a pressure inlet, a pressure outlet and a pressure relief port on the direct-acting two-position three-way solenoid valve, and the electromagnetic control device is used to control the conduction and disconnection of the pressure outlet and the other two ports. Different pressures will produce different pressures on the seals that block the pressure port, so that the existing solenoid valves cannot meet the applications of different pressures at the same time. For example, most of the 0-0.7MPa pneumatic solenoid valves available on the market cannot be used. Even in vacuum pressure occasions, it cannot be applied to occasions with pressures above 0.7MPa

Embodiment
[0022] Such as Figure 1-Figure 4 As shown, the multi-purpose electromagnetic valve described in this embodiment includes an electromagnetic control device 1 and a valve body 2. The valve body 2 has a valve inner cavity 20, and the electromagnetic control device 1 is installed at the opening end of the valve inner cavity 20; A valve stem 3 is placed in the cavity 20, and a first channel 21, a second channel 22, and a third channel 23 are provided on the inner wall thereof; a valve core 30 is arranged on the valve stem 3, and the electromagnetic control device 1 controls the displacement of the valve stem 3 Afterwards, the passage that makes the second passage 22 communicate with the third passage 23 is blocked by the spool 20 and disconnected, while the second passage 22 communicates with the first passage 21, or the passage that makes the second passage 22 communicate with the first passage 21 The channel is blocked and disconnected by the spool 20, and the second channel 22 ...

A multi-purpose electromagnetic valve disclosed by the present invention includes an electromagnetic control device and a valve body, the valve body has a valve inner cavity, and the electromagnetic drive device is installed at the opening end of the valve inner cavity; a valve stem is placed in the valve inner cavity, and its The inner wall has a first channel, a second channel and a third channel; the valve stem is provided with a valve core, and after the electromagnetic drive device controls the displacement of the valve stem, the channel connecting the second channel and the third channel is blocked by the valve core and disconnected, and the second passage communicates with the first passage, or the passage connecting the second passage and the first passage is blocked by the spool to disconnect, and the second passage communicates with the third passage. Its structure promotes the displacement of the valve stem through electromagnetic control, and prompts the valve core to control the switching and communication between multiple channels, so that the use methods are diversified, and it is especially suitable for fields that require multi-channel switching.
Description
technical field [0001] The invention relates to the technical field of electric control valves, in particular to a multipurpose electromagnetic valve. Background technique [0002] At present, there will be a pressure inlet, a pressure outlet and a pressure relief port on the direct-acting two-position three-way solenoid valve, and the electromagnetic control device is used to control the conduction and disconnection of the pressure outlet and the other two ports. Different pressures will produce different pressures on the seals that block the pressure port, so that the existing solenoid valves cannot meet the applications of different pressures at the same time. For example, most of the 0-0.7MPa pneumatic solenoid valves available on the market cannot be used. Even in the case of vacuum pressure, it cannot be applied to the occasion of pressure above 0.7MPa. Contents of the invention [0003] The object of the present invention is to solve the deficiency of the above-men...
