Description
Technical field
This utility model relates to a kind of electromagnetic valve.
Background technology
Electromagnetic valve is the industrial equipment by Electromagnetic Control, is used to control the automation foundation element of fluid, belongs to executor, however it is not limited to hydraulic pressure, pneumatic.It is used in industrial control system and adjusts the direction of medium, flow, speed and other parameter.Electromagnetic valve can coordinate different circuit to realize intended control, and the precision controlled and motility can ensure.Electromagnetic valve has a variety of, and different electromagnetic valves plays a role at the diverse location of control system, is most commonly used that check valve, relief valve, directional control valve, speed-regulating valve etc..
Airtight chamber is had in electromagnetic valve, having through hole at diverse location, each hole connects different oil pipes, is piston in the middle of chamber, two sides is two blocks of electric magnet, which side the magnet coil energising valve body in which face will attracted to, and is turned on and off different outages by the movement of application valve body, and fuel feed hole is normally opened, hydraulic oil will enter different oil exit pipes, then promoted the piston of oil cylinder by the pressure of oil, piston drives again piston rod, piston rod driving mechanical device.So just control mechanical movement by the current switching of control electric magnet.Electromagnetic valve is to produce magnetic force after solenoid is energized to attract to overcome the press belt movable valve plug action of spring, with regard to a solenoid, simple in construction, low price, can only realize switch；Electrodynamic valve is that electrodynamic valve divides again (shut-off valve) and regulation valve by motor-driven valve rod, band movable valve plug action.Shut-off valve is the work i.e. standard-sized sheet of two formulas and fully closed, and regulation valve is above installing electric valve locater, is regulated by closed loop and makes valve stable on a position dynamically.
Current existing electromagnetic valve, when hydraulic pressure is higher, regulates less stable, and degree of regulation is low, inconvenient operation, and security performance is the highest.
Utility model content
It is reliable and stable that the technical problems to be solved in the utility model is to provide a kind of regulation, easy to operate, uses safe electromagnetic valve.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of electromagnetic valve, including valve body, valve seat, main valve plug and shell, described valve seat is located in valve body, described valve seat is fixedly connected with the valve body, described main valve plug is located on valve seat, described main valve plug both sides are provided with through hole, described main valve plug is that hollow is arranged, it is provided with valve rod on described main valve plug, described main valve plug is connected with valve rod clamping, described shell is located on valve body, coil and insulating shield it is provided with in described shell, described insulating shield is connected with body seal, described cover top portion is provided with fixed core, it is provided with spring below described fixed core, described fixed core is connected with valve rod by spring.
As preferably, in the middle part of described insulating shield, it is provided with sealing ring.
As preferably, described shell welds with valve body.
As preferably, described fixed core is fixing with shell to be connected.
As preferably, described insulating shield two ends are that projection is arranged.
The beneficial effects of the utility model are: the main valve plug both sides of setting are provided with through hole and main valve plug is that hollow is arranged, it is possible to keeping main valve plug when closed, liquid can flow into so that the hydraulic pressure of valve seat both sides is equal, keeps regulation reliable and stable, easy to operate；The insulating shield arranged keeps safe and reliable, and insulation effect is good；The coil arranged enables to fixed core compression spring absorption valve rod after powered up so that move on spool；The spring arranged can produce elastic force to valve rod, under no power state, spool is closed.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of electromagnetic valve of this utility model.
Detailed description of the invention

It is provided with sealing ring 11 in the middle part of described insulating shield 8, keeps good sealing effectiveness.
Described shell 4 welds with valve body 1 so that Stability Analysis of Structures is reliable.
Described fixed core 9 is fixing with shell 4 to be connected, and keeps fixed core 9 Stability Analysis of Structures.
Described insulating shield 8 two ends are that projection is arranged, and keep insulating shield 8 to firmly install.
The beneficial effects of the utility model are: the main valve plug both sides of setting are provided with through hole and main valve plug is that hollow is arranged, it is possible to keeping main valve plug when closed, liquid can flow into so that the hydraulic pressure of valve seat both sides is equal, keeps regulation reliable and stable, easy to operate；The insulating shield arranged keeps safe and reliable, and insulation effect is good；The coil arranged enables to fixed core compression spring absorption valve rod after powered up so that move on spool；The spring arranged can produce elastic force to valve rod, under no power state, spool is closed.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
