Description
Technical Field
The utility model relates to a self-sustaining solenoid valve.
Background
The self-holding electromagnetic valve is controlled to open and close by a valve opening coil and a valve closing coil. When the valve opening coil is electrified, the valve opening movable iron core is sucked and lifted, the pilot hole is conducted, the valve opening is completed, meanwhile, the valve closing movable iron core is popped out due to the action of the spring to clamp the valve opening movable iron core, and the valve opening state is still realized after the power failure. When the valve closing coil is electrified, the valve closing movable iron core is sucked, the valve opening movable iron core blocks the pilot hole due to the thrust and gravity of the spring, the valve closing is completed, and the valve closing state is still realized after the power failure. Under the actual working condition environment, due to the vibration of the field environment, after the valve closing movable iron core is displaced, the valve opening movable iron core falls down to block the pilot hole, so that the malfunction of the valve closing is caused.

The utility model aims at solving the above problem, providing a self-sustaining solenoid valve of stable performance, also can not cause the shut-off malfunction when having the vibration under the open valve state.
The technical scheme of the utility model as follows:
a self-sustaining solenoid valve of stable performance includes: the valve opening device comprises a valve opening coil (3), a valve opening non-magnetic pipe (4), a valve opening spring (5), a valve opening movable iron core (6), a center column (7), a valve closing movable iron core (8), a valve closing spring (9), a valve closing non-magnetic pipe (10), a valve closing coil (11), a PTFE pad (12), a pilot hole (13), a solenoid valve cover (14), an annular step (15), a groove A (16), a groove B (17) and a solenoid valve body (18).
The middle column (7) is fixed on a valve cover (14) of the electromagnetic valve, a valve-opening non-magnetic pipe (4) is fixed on the top of the middle column (7), a valve-opening coil (3) is fixed outside the valve-opening non-magnetic pipe (4), a valve-opening movable iron core (6) is placed in the valve-opening non-magnetic pipe (4), the valve-opening movable iron core (6) is also placed in a hole of the middle column (7), a valve-closing non-magnetic pipe (10) is fixed on the side face of the middle column (7) and is perpendicular to the valve-opening non-magnetic pipe (4), a related valve coil (11) is fixed outside the valve-closing non-magnetic pipe (10), a valve-closing movable iron core (8) is placed in the valve-closing non-magnetic pipe (10), a valve-closing spring (9) is placed in a hole of the side face of the valve-closing movable iron core (8), and when the electromagnetic valve is opened, the valve-closing movable iron core (8) is in contact with the valve-opening movable iron core (6).
A groove B (17) is formed in the end of the valve opening movable iron core (8), and a groove A (16) is formed in the lower surface of an annular step (15) of the valve opening movable iron core (6).
When the electromagnetic valve is to be opened, the valve closing coil (11) is not opened, only the valve opening coil (3) is opened, the valve opening coil (3) is electrified, the valve opening movable iron core (6) moves upwards, the pilot hole (13) is conducted, and the valve opening is completed, meanwhile, the valve closing movable iron core (8) moves towards the valve opening movable iron core (6) under the thrust of the valve closing spring (9) and is clamped in the groove A (16) in the lower surface of the annular step (15) on the valve opening movable iron core (6), the valve opening movable iron core (6) is clamped, the valve opening state is still realized after the power failure, and the false operation of the valve closing caused by the fact that the pilot hole (13) is blocked due to the displacement of the valve closing movable iron core (8) caused by the vibration of the field environment is avoided. It can be seen that when the valve closing movable iron core (8) is contacted with the valve opening movable iron core (6) and clamped, the valve closing movable iron core does not generate displacement during vibration, and the state of the valve opening movable iron core (6) does not change, so that the valve opening state is kept unchanged, and the generation of misoperation of valve closing is effectively inhibited. The position of a groove B (17) at the end part of the valve-closing movable iron core (8) corresponds to the position of a groove A (16) in the lower surface of an annular step (15) on the valve-opening movable iron core (6).
When the electromagnetic valve is closed, the valve closing coil (11) is opened, and the groove B (17) at the end part of the valve closing movable iron core (8) moves out of the groove A (16) in the lower surface of the annular step (15) on the valve opening movable iron core (6). The valve opening movable iron core (6) falls down to block the pilot hole (13) due to the thrust and the gravity of the spring, and the valve closing action is completed.
