Abstract
The utility model relates to a diaphragm explosion-proof two-position self-locking electromagnetic valve. A soft magnet (11), a permanent magnet (15) and a soft magnet (13) are arranged along the drive rod (6) in a coaxial mode, magnetizing coils (12) (14) are respectively arranged in the soft magnets, and the two coils are inversely connected in series. The opposite ends of the two soft magnets have the same magnetic performance when power is switched on, and the opposite ends of the two soft magnets and both ends with fixed magnetic performance of the permanent magnet form repulsion one side and attraction on the other side. The drive rod (6) and the permanent magnet (15) are tightly matched; under the drive of a combine magnetic force, a valve core (5) is in an open or close state. After the power is switched off, the soft magnet (11) or (13) which tightly close to the permanent magnet (15) is magnetized by the permanent magnetism, the attraction is more firm, and the state is just like a self-locking state. The time to change a locking position is determined by people, the used pulse current has the advantages of transience and energy saving, and a diaphragm (7) is used for sealing and isolating fuel gas. The utility model receives the effect of supervision for the fuel gas.
Description
The utility model relates to a kind of solenoid valve that is used for combustion gas control, refers to the explosion-proof dibit self-locking electromagnetic valve of barrier film especially.
Present universaling electromagnetic valve relies on electric current to maintain " opening " or "off" state, not only power consumption, and can not solve needs to the domestic gas use and management.This special electromagnetic valve is required:
1, anti-ly fire 2, dibit locking 3, economize on electricity
The purpose of this utility model is to provide a kind of explosion-proof, self-locking and energy-conservation solenoid valve.
Its structure, working principle see also Fig. 2, Fig. 3, are summarized as follows:
The coaxial setting of this solenoid valve: soft magnetic bodies-permanent magnet-soft magnetic bodies respectively is provided with a field coil, two coil differential concatenations in the soft magnetic bodies of two ends.The end in opposite directions of two soft magnetic bodies is identical polar (or be the N utmost point or be the S utmost point) when energising, permanent magnet two ends magnetic immobilizes, one side and the soft magnetic bodies same sex, the opposite side and the soft magnetic bodies opposite sex, one inhales one scolds and closes magnetic force permanent magnet is moved along axle,, promptly be close to after putting in place on the soft magnetic bodies end face to this from that.After the outage, be close to soft magnetic bodies adhesive more firmly under magnetization of permanent magnet, just as locking, this is self-locking.The time that changes locked position is determined by the people.As apply a reverse impulse electric current, and situation is just the opposite, and permanent magnet promptly leaves former locked position, switches to be adjacent to another soft magnetic bodies and same locking.
How to realize below in conjunction with description of drawings the utility model:
Fig. 1, structure sectional view of the present utility model
Fig. 2, Fig. 3, the utility model fundamental diagram
The drawing explanation:
(1) air inlet (2) exhaust (3) valve body
(4) valve opening (5) spool (6) driveshaft
(7) barrier film (8) sealed screw
(9), (18) flange plate (11), (13) jar shape soft magnetic bodies
(12), (14) field coil (15) permanent magnet
(16) antifreeze plate (17) shell
Shown in Figure 1, comprise gas valve and Electromagnetic Control, by barrier film (7) airtight every From, and integrator by ring flange (9), (18) and shell (17). This Plant setting, purpose is anti-to be fired.
Gas valve partly comprises valve body (3), valve opening (4), spool (5) and barrier film (7), wherein drive rod (6) is connected as a single entity spool (5) and Electromagnetic Control. As Fruit is opened spool (5), and air inlet (1) is communicated with exhaust (2); If close (5), gas supply interrupts.
Electromagnetic Control partly comprise tank shape soft magnetic bodies (11)-permanent magnet-(15)-Soft magnetic bodies-(13), and along the axial setting of drive rod (6), wherein soft magnetic bodies (11), (13) and bar (6) be slidingly matched, permanent magnet (15) is tight with bar (6) Cooperate also together mobile with bar (6), moving range: soft magnetic bodies (11) right side and Between soft magnetic bodies (13) left side. Soft magnetic bodies (11), (13) are respectively equipped with excitatory Coil (12), (14), two coil differential concatenations. Permanent magnet (15) both ends of the surface respectively Post one deck non-magnetic sheet (16).
Shown in Figure 2, permanent magnet (15) two ends magnetic immobilizes, and is the left N right side such as figure S, when the extreme face of N was close to soft magnetic bodies (11) right side, spool (5) was closed. At this moment, spool (5) is opened in the wish order, namely gives a pulse current by A → B, soft magnetism (11), the in opposite directions end of (13) all is the N utmost point, permanent magnet (15) is subjected to a side repulsion With the magneticaction that closes of opposite side suction, moving to right puts in place is fitted in soft magnetic bodies (a 13) left side End face, spool (5) is opened.
Shown in Figure 3, be close to soft magnetic bodies (13) left side when the extreme face of permanent magnet (15) S, spool (5) is opened.At this moment, spool (5) is closed in the desire order, promptly give a reverse impulse electric current by B → A, the end in opposite directions of soft magnetic bodies (11), (13) all is the S utmost point, permanent magnet (15) is changed by force direction, one side draught power and opposite side repulsion, this closes magnetic force makes permanent magnet (15) leave soft magnetic bodies (13) to shifting left and being fitted in soft magnetic bodies (11) right side, and spool (5) is closed.
The utility model advantage is to make the combustion gas control electromagnetic valve to realize explosion-proof and auto-lock function, thereby receives and can use the effect of carrying out supervision to combustion gas.
