Abstract

The invention discloses a semiautomatic electromagnetic valve capable of locking heavy load and achieving low-power-consumption and reliable unlocking. One end of a moving component moving in a seal channel of a valve deck up and down is connected with a knuckle bearing at the rod end of a self-lubricating ball stud, and the other end of the moving component is connected with the heavy load; the other end of the knuckle bearing is connected with a driven rod; one end of a linkage rod is in pin connection with one end of a movable iron core; one end of a driving rod is connected with a power rotating head through a drive shaft; a fixed iron core, a coil and the movable iron core moving in the axial direction are arranged in a plastic package electromagnetic coil; the valve is in an open state and the heavy load is locked when the permanent magnet force of the fixed iron core to the movable iron core is greater than the axial component force of the resultant force of the gravity of the moving component and airtight power spring force to the movable iron core; and the moving component is gently unlocked and moves downwards to close the valve when the permanent magnet force of the fixed iron core to the movable iron core is smaller than the axial component force of the resultant force of the gravity of the moving component and airtight power spring force to the movable iron core. The semiautomatic electromagnetic valve has the advantages of heavy load locking and low-power-consumption and gentle unlocking.

Description

technical field

[0001] The invention relates to the technical field of electromagnetic locks for electromagnetic valves, in particular to a semi-automatic electromagnetic valve that locks heavy loads and can be reliably unlocked with low power consumption. Background technique

[0002] At present, the heavy-duty electromagnetic gas emergency shut-off valve in the market is a bayonet type lock tongue solenoid valve, which adopts a multi-stage lock tongue structure in order to lock heavy loads and unlock with low power consumption. However, since the force value needs to be transmitted through multiple stages and most of the lock bolts are under one-way side force, the unlocking is unreliable especially when the number of switches is large, and the opening of the electromagnetic gas emergency shut-off valve is direct-acting, and the opening force is very large. .

[0003] At present, there are electromagnetic gas emergency shut-off valves with a valve-opening booster structur...

Embodiment Construction

[0045] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] Such as Figure 1-Figure 6 As shown, the first embodiment of the present invention provides a semi-automatic solenoid valve that locks heavy loads and reliably unlocks with low power consumption. The joint bearing 5 is threaded to ensure reliable sealing when the moving part 2 moves up and down in the sealing channel of the valve cover 4 , and at the same time, it will not limit the installation direction of the actuator housing 14 . The other end of the moving part 2 is connected with a heavy load. The other end of the joint bearing 5 at the end of the self-lubricating ball stud bolt is pin-connected with the driven rod 6, and has an automatic compensation function when the size deviates. The other end of the driven rod 6 is pin-connected with the driving rod 7 and the linkage rod 8, and the connection between the driven rod 6, the driving ro...
