Abstract
The utility model relates to an electromagnetic controlled diaphragm valve, which is composed of a valve body (13), a valve cover (15), a diaphragm (14) and a control spring (16), wherein the diaphragm (14) is arranged between the valve body (13) and the valve cover (15), and the control spring (16) is arranged between the valve cover (15) and the diaphragm (14). The diaphragm (14) is provided with a balancing hole (18), the valve cover (15) is provided with a communicating pipe (10) which extends into the valve body (13), and the top end of the communicating pipe (10) is provided with an electromagnetic mechanism and a manual switch (9). The utility model has the advantages of zero wear when the valve is opened and closed, no easy blockage by impurities, agile opening and closing operation, etc.
Description
The utility model belongs to a kind of electromagnetic mechanism that utilizes and controls the motion of valve pocket inner septum indirectly, to realize the valve of opening and closing.
Existing electromagnetic valve structure adopts servo formula, piston sealing structure, and the magnetic field that forms behind the coil electricity in the electromagnetic mechanism picks up moving iron core, and fluid floats piston, opens valve.During coil losing electricity, moving iron core and piston deadweight fall to valve port being stopped up valve closing.This solenoid valve valve port directly contacts with electromagnetic mechanism, is stopped up by impurity easily, causes defective valve; In addition, the piston of this solenoid valve and piston cylinder produce very big friction, greatly reduce the life-span of valve.
The purpose of this utility model provides a kind ofly can not stopped up.There are not wearing and tearing, and the Electromagnetic Control membrane valve that is active in one's movements.
For achieving the above object, the Electromagnetic Control membrane valve that the utility model is taked is made up of the barrier film between valve body, valve gap, valve body and the valve gap, control spring between valve gap and barrier film, and barrier film has an equalizing orifice; Valve gap has the connecting tube of stretching into body cavity; The top of connecting tube is provided with electromagnetic mechanism and hand switch.
Electromagnetic mechanism is made up of the spring in shell, lead, coil, skeleton, static iron core, the moving iron core, the liner that is fixed on moving iron core bottom from outside to inside successively.
One end of hand switch has cam, and the other end has socket.
Owing to the utility model is utilize to change barrier film epicoele and valve to enter the cavity fluid pressure difference and obtain fluid and promote the opening and closing that barrier film upper and lower in-migration is finished sprue voluntarily, therefore there is not abrasion fully, and the reaction agility; Because valve port of the present utility model does not directly contact with electromagnetic mechanism, and the balance aperture size of barrier film is scalable, therefore be unfavorable for the obstruction of impurity such as silt again.
Below in conjunction with accompanying drawing embodiment of the present utility model is done further detailed description.
Fig. 1 is the structural representation of the utility model Electromagnetic Control membrane valve closed condition.
Fig. 2 is the structural representation of the utility model Electromagnetic Control membrane valve on state.
Fig. 3 is the plan view of hand switch.
Fig. 4 is the left view of hand switch shown in Figure 3.
The utility model Electromagnetic Control membrane valve structural drawing shown in Figure 1, when electromagnetic mechanism cut off the power supply, lead 1 no current passed through, coil 2 no electric circuits, moving iron core 7 falls under spring 6 effects, and the liner 8 that is contained in moving iron core 7 ends is blocked and connecting tube is entered the mouth 17 also along with falling.This moment, greater than 14 times cavity pressures of barrier film, barrier film 14 falls rapidly under the tension force effect of this pressure difference and control spring 16, blocks the inlet of exhaust chamber 11, valve closing by the upper cavity pressure with barrier film 14 that good elasticity and flexible rubber makes.
Shown in Figure 2, when electromagnetic mechanism is switched on, electric current makes coil 2 also charged by lead 1, the magnetic field that coil 2 produces makes iron core 7 inhale mutually with static iron core 6, spring 6 is compressed, the rising of moving iron core 7 drives liner 8 and rises, liner 8 leaves and connecting tube enters the mouth 17, this moment, barrier film 14 epicoeles and exhaust chamber 11 were communicated with by connecting tube 10, the pressure that enters chamber 12 inner fluids is greater than barrier film 14 epicoele hydrodynamic pressures, barrier film 14 is risen, and the fluid that enters chamber 12 directly passes through the inlet inflow and outflow chamber 11 of exhaust chamber 11, valve conducting.
The utility model Electromagnetic Control membrane valve can also be only with the opening and closing that manually come control valve.Fig. 3 and hand switch shown in Figure 49 structures, these hand switch 9 one ends have a cam 20, and the other end has a socket 19, and when cam 20 down the time, the liner 8 on the moving iron core 7 stops up connecting tube inlet 17, valve closing.Act on when external force on the socket of hand switch 9, and make hand switch rotate 180., then cam 20 up, from connecting tube inlet 17, at this moment, barrier film 14 epicoeles are communicated with exhaust chamber 11 protruding part on the cam 20, then move the valve conducting on the barrier film 14 with liner 8 top.
