Problems solved by technology

[0002] At present, almost all solenoid valves are driven and maintained by electromagnets. Regardless of the normally open or normally closed type, there is always a switching action and a state that require power consumption.
Moreover, the switching action of this type of solenoid valve is affected by various factors such as lubrication, so it is difficult to guarantee the long-term reliability of the work; at the same time, this type of solenoid valve not only consumes energy during work, but also causes inaccurate closing due to current fluctuations. There are hidden dangers of strict or unstable flow, but in many applications, especially low pressure occasions, this kind of strong maintenance through energy consumption is unnecessary

Embodiment Construction

[0010] In the structural view of the low-power normal-pressure solenoid valve shown in Figure 1 and the structural view of the armature part of the low-power normal-pressure solenoid valve shown in Figure 2: the electromagnetic coil (1) is sleeved on the skeleton of the valve body (11) part (3), and is protected by the coil sheath (2). At the rear end of the inner cavity of the skeleton part (3), a swingable bar plate-shaped armature (5) is installed through the shaft structure (4). A large gasket (7) made of elastic material is consolidated on both sides. At the first outlet (10) and the second outlet (12) of the conversion chamber (6), small sealing gaskets (8) made of elastic materials are fixed respectively, and their central holes are aligned with the corresponding outlets. At the first outlet (10) and the second outlet (12) of the valve body (11), permanent magnets (9) are inlaid with the same polarity. At the first outlet (10), the second outlet (12) and the inlet (14...

Abstract

The invention discloses a low-power consumption energy-saving two-position solenoid valve maintained without brute force. The solenoid valve utilizes the attraction of a permanent magnet to a armature to realize the stable maintenance of a working state, and utilizes the interaction between the permanent magnet and a movable electromagnet to realize the quick conversion of the working state; therefore, unnecessary energy consumption of the solenoid valve is reduced, the stable maintenance of the working state is realized, and simultaneously the working reliability of the solenoid valve is improved.

Description

Technical field [0001] The invention relates to a hydraulic control device, in particular to an electromagnetic valve. Background technique [0002] At present, almost all solenoid valves are driven and maintained by electromagnets. Regardless of the normally open or normally closed type, there is always a switching action and a state that require power consumption. Moreover, the switching action of this type of solenoid valve is affected by various factors such as lubrication, so it is difficult to guarantee the long-term reliability of the work; at the same time, this type of solenoid valve not only consumes energy during work, but also causes inaccurate closing due to current fluctuations. There are hidden dangers of strict or unstable flow, but in many applications, especially low pressure occasions, this kind of strong maintenance through energy consumption is unnecessary. This requires the development of an energy-saving solenoid valve that does not need to be strongl...
