Embodiment

A kind of sand canister magneto-controlled breather valve as shown in Figure 1 and 2, including it is valve body 1, electromagnet, partition 4, plate 3 of holding one's breath, close Seal washer 5, wherein valve body 1 is that only valve body 1 is divided by the hollow rectangular body mechanism there are four side, the partition 4 of 1 centre of valve body It exhales valve, inhale valve two parts, as shown in Figure 1, the lower section of Fig. 1 is connected to corresponding tank body, the valve opening on the left side is to exhale valve, the valve opening on the right To inhale valve, partition 4 is hollow structure, for placing the conducting wire of electromagnet.

Plate 3 of holding one's breath is the certain hollow structure of wall thickness, and valve opening can be completely covered in when horizontal position, and breather valve is by holding one's breath The folding of plate 3 adjusts the air pressure in sand canister tank body (abbreviation tank body), and limiting section 9 is located inside valve body 1, cross sectional shape is The protrusion of rectangle, limiting section 9 are used to limit the movement for plate 3 of holding one's breath, and make to exhale the plate 3 of holding one's breath in valve can only be in the rotation of shaft 6 The heart is rotated up 90 °, and 90 ° can only be rotated towards tank body direction with 6 rotation center of shaft by making to inhale the plate 3 of holding one's breath in valve, such as Fig. 1 institute Show, breather valve exhales the plate 3 of holding one's breath of valve to open outwardly, and that inhales valve holds one's breath 3 opening direction of plate in contrast, when pressure in tank body When excessive, the plate 3 of holding one's breath of valve is exhaled to open release excess pressure, when tank body pressure is subatmospheric, the plate 3 of holding one's breath for inhaling valve is beaten It opens, increases pressure inside the tank；Valve, suction valve is exhaled to be provided with two blocks of plates 3 of holding one's breath, the cavity between two blocks of plates 3 of holding one's breath is provided with pressure Gap sensor 2, when gas leakage, can cause the pressure change of cavity between two blocks of plates 3 of holding one's breath, and differential pressure pickup 2 is able to detect that and reports It is alert.

Electromagnet is divided into the first electromagnet 7 in plate 3 of holding one's breath, the second electromagnet 8 being vertically arranged on partition 4, the first electricity Magnet 7 is several cyclic annular electromagnet, in the hollow cavity for holding one's breath plate 3, and along the edge distribution of hollow cavity；Limit Portion 9 is conductor, and the part that limiting section 9 is contacted with plate of holding one's breath is equipped with seal washer 5, and the first electromagnet 7 is in magneticaction when use Lower close limiting section 9, so that the closure of plate 3 of holding one's breath；Second electromagnet 8 is arranged on partition 4, the magnetic pole of the second electromagnet 8 and the The magnetic pole of one electromagnet 7 is identical, is exhaling valve, when hold one's breath plate 3 because in tank body pressure it is too big and when opening, can be towards the second electromagnetism Iron 8 is close, and due to homopolar-repulsion, the second electromagnet 8 applies a repulsion to it, and plate 3 of holding one's breath is by air pressure in tank and the second electricity The effect of 8 repulsion of magnet, the magnetic force of air pressure and the second electromagnet 8 reaches balance in 3 opening state of plate of holding one's breath in tank, when gas in tank When body pressure reduces, the balance of power is broken, and plate 3 of holding one's breath is pushed to closed position under electromagnetic force, close to closed position When, the first electromagnet 7 tightly adsorbs realization closure under magneticaction with limiting section 9.

Its specific works situation is as follows:

The magnetic force size that adjusting the first electromagnet 7 and the second electromagnet 8 is only needed when use, keeps the magnetic force of all electromagnet big It is small identical as the pressure size of control required in tank, specifically exhale valve to hold one's breath the balanced type of 3 both ends power of plate: atmospheric pressure+electromagnetism Power=pressure inside the tank；It inhales valve to hold one's breath the mechanical balance formula at 3 both ends of plate: atmospheric pressure=pressure inside the tank+electromagnetic force.

When pressure inside the tank is excessive: the excessive pressure to plate 3 of holding one's breath of pressure inside the tank also will increase, and in exhaling valve, gas is to closing The pressure of gas plate 3 is greater than the magnetic force of the first electromagnet 7, i.e. atmospheric pressure+electromagnetic force < pressure inside the tank, so that the opening of plate 3 that makes to hold one's breath is released It puts extra air pressure to second to hold one's breath plate 3, second plate 3 of holding one's breath also is opened because of above-mentioned principle, and excessive air pressure is discharged, is closed Gas plate 3 is arranged close to the second electromagnet 8 on partition 4, the first electricity in the magnetic pole of the second electromagnet 8 and plate 3 of holding one's breath after opening The magnetic pole of magnet 7, electromagnetic force are identical, and since identical charges repel each other, the second electromagnet 8 is applied with the first electromagnet 7 held one's breath in plate 3 One power opposite with partition 4, this power and the magnetic picture of the first electromagnet 7 are same, and when extra air pressure is discharged, gas is to holding one's breath When the pressure of plate 3 reduces, the repulsion of the second electromagnet 8 plate 3 that just will hold one's breath pushes back closed position, under electromagnetic force, first Electromagnet 7 is combined closely again with limiting section 9.

Valve is inhaled due to inwardly opening, and is provided with limiting section 9, as shown in Figure 1, therefore cannot open, guarantees exhaust When only exhale valve working.

When pressure inside the tank is too small: atmospheric pressure > pressure inside the tank+electromagnetic force exhales valve can only be outside due to being provided with limiting section 9 It opens, to cannot work, the plate 3 of holding one's breath for inhaling valve is rotated for the center of circle to tank body direction with shaft 6, and atmospheric pressure enters in tank body, Close to the second electromagnet 8 after plate 3 of holding one's breath rotation, it is similarly subjected to the repulsion of the second electromagnet 8, when atmospheric pressure=pressure inside the tank+electromagnetism When power, the repulsion plate 3 that will hold one's breath pushes back closed position.

When gas leakage: since under closed state, the cavity pressure between two blocks of plates 3 of holding one's breath is stable, once there is gas leakage must It so will lead to pressure to change, the differential pressure pickup 2 being disposed therein just can detect this slight change and alarm, thus Automatic detection is realized, without manual inspection.

When 6 Caton of shaft: 6 Caton of shaft causes to hold one's breath the case where can not being closed or being closed loosely of plate 3, will lead to two Block is held one's breath the pressure change of 3 internal cavity of plate, again may be by differential pressure pickup 2 to detect, the pressure due to caused by Caton Variation is big compared with pressure change caused by gas leakage, go wrong so can be offered an explanation by the signal of differential pressure pickup 2.

Embodiment as one preferred, the electromagnet, shaft, differential pressure pickup, seal washer are highly developed The prior art, can directly buy.

Embodiment as one preferred, the hollow plate of holding one's breath for having certain wall thickness is integrally cast by aluminium.

Embodiment as one preferred, the valve body material are spheroidal graphite cast-iron.

In the present embodiment, what the equal right and wrong of connection type, control mode of several first electromagnet were usually advised in plate of holding one's breath shows There is technology, therefore is not illustrated.
