The upper housing and lower case of glue gasket are threadedly coupled, and connector is connect by screw, elastomeric pad and insulation rubber mat with cushion block；Bullet
Spring is installed on core bar by two spring bases and adjustment gasket；Set is individually fixed in the groove on cushion block and connector；It is anti-
Dirt sealing shroud is installed in the groove of jointing lower end surface, and jointing is fixed on upper housing by screw；Button and core
Bar is threadedly coupled, and is locked by holding screw；Cap is threadedly coupled with jointing；Gland is prevented rubber by screw
Konisphere is fixed in the groove of lower case；The shaft coupling is connect with core bar lower thread, and with lock sleeve and nut and locking
Gasket is locked.
The core bar includes the first screw rod, middle core bar and the second screw rod, the first screw rod and the second screw rod and middle core bar screw thread
Connection, and locked by holding screw.
The electromagnetic coil is entwined after being welded to each other by coil, copper sheet and copper pipe.
The upper housing and lower case are equipped with for electromagnetic coil external connection and logical with power distribution equipment and control device
Welding point.
There are certain gaps by adjusting adjustment gasket for the cushion block and the spring base of top, to guarantee the precompressed of spring
Contracting amount does not change.
There are shut down slide valve with starting to carry out overlapped notch for the lock sleeve.
Beneficial effects of the present invention: reasonable in design, securely and reliably, it is long-range with conventional electromagnets that this directly drives electromagnet
Remote control function and Manual local manipulation and control function.Long-range control manipulation can not carry out simultaneously with manually handle on the spot.
For the straight electromagnet cooperation starting shutdown slide valve that drives there are three types of location status and two kinds of working conditions, three kinds of location status are starting shape
State, equilibrium state and shutdown status, two kinds of working conditions are starting working condition and shut down working condition, equilibrium state not shadow
Working condition before sound.Equilibrium state is under normal condition, when unit needs to start, the straight electromagnet that drives is in starting shape
State returns to equilibrium state after start completion, and unit is in starting state at this time；It is straight to drive at electromagnet when unit needs to shut down
Equilibrium state is returned to after shutdown status, shutdown, unit is in shutdown status at this time.In power supply or manually handle start and stop,
When stopping power supply or stopping manually handle, the straight electromagnet that drives automatically returns to equilbrium position.Manually handle need to open cover when starting
Cap, when shutdown, do not need to open cap, can direct Push button.
