Abstract
The utility model relates to an electromagnetic valve, referring in particular to a water intake control electromagnetic valve for water clarifier. The utility model adopts the following art scheme: an electromagnetic valve including a valve body, an electromagnetic control device ed on the valve body and a piston between the valve body and the electromagnetic control device and capable of switching on/off the water flow in the valve; the piston and the internal-sealing casing inside the electromagnetic control device form a cavity; and a power-assisted spring is positioned between the piston and the internal-sealing casing inside the electromagnetic control device. Through the adoption of the above art scheme, the utility model overcomes the disadvantage of prior art, providing a new electromagnetic valve that will not leak water under usual conditions.
Description
Technical field
The utility model relates to a kind of solenoid valve, is meant the water inlet control electromagnetic valve that is used on the water treatment tank especially.
Background technique
At present, with the immediate a kind of solenoid valve of the utility model, but it includes valve body, be arranged on the Electromagnetic Control mechanism of valve body upper end, the piston of break-make valve body current also between valve body and Electromagnetic Control mechanism, described piston is by support and be socketed on the support seal ring and form, offer through hole on the central position of described piston, this through hole cooperates with motion bar break-make in the Electromagnetic Control mechanism, described eccentric part at piston is provided with the by-pass hole that always is on state, and the diameter of this by-pass hole is slightly less than the diameter of through hole.The solenoid valve of this structure exists a problem, and under the less situation of hydraulic pressure of water inlet, the hydraulic pressure deficiency by by-pass hole is so that piston resists the osculum on the valve body, and solenoid valve has water leakage phenomenon like this; Under the situation that water flow is big when driving valve, piston is easily by water impact, and the current cutout can lag behind when coil blackout.
Summary of the invention
The utility model has overcome the deficiency that prior art exists, and a kind of its watertight novel solenoid valve that under any circumstance can guarantee is provided.
Realize above-mentioned purpose, the utility model adopts following technological scheme: a kind of solenoid valve, but include valve body, be arranged on the Electromagnetic Control mechanism of valve body upper end, the piston of break-make valve body current also between valve body and Electromagnetic Control mechanism, interior seal casinghousing in this piston and the Electromagnetic Control mechanism constitutes a cavity, is provided with power assistant spring between the described interior seal casinghousing in piston and Electromagnetic Control mechanism.
Further setting of the present utility model is: described piston is by support and be socketed on the support seal ring and form, offer through hole on the central position of described piston, this through hole cooperates with motion bar break-make in the Electromagnetic Control mechanism, described eccentric part at piston is provided with the by-pass hole that always is on state with the water inlet, and the diameter of this by-pass hole is less than the diameter of through hole.
Beneficial effect: by being provided with power assistant spring between the interior seal casinghousing in piston and Electromagnetic Control mechanism.Can make under the very little situation of intake pressure,, guarantee that piston resists the osculum on the valve body, thereby overcome the not enough of prior art existence and improved current cutout speed and the reliability of current cutout by the elastic force of power assistant spring.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment closed condition;
Fig. 2 is the structural representation of open mode among Fig. 1;
Embodiment
As shown in the figure, a kind of solenoid valve, but include valve body 1, be arranged on the Electromagnetic Control mechanism 2 of valve body 1 upper end, between valve body 1 and Electromagnetic Control mechanism 2 and the piston 3 of break-make valve body 1 current, interior seal casinghousing 21 in this piston 3 and the Electromagnetic Control mechanism 2 constitutes a cavity 4, described piston 3 is by support 31 and be socketed on the support 31 seal ring 32 and form, offer through hole 33 on the central position of described piston 3, in the time of in off position, the lower end of this through hole 33 communicates with osculum 11 on the valve body 1; The upper end of this through hole 33 cooperates with motion bar 22 break-makes in the Electromagnetic Control mechanism 2, and described eccentric part at piston 3 is provided with the by-pass hole 34 that always is on state with water inlet 12, and the diameter of this by-pass hole 34 is less than the diameter of through hole 33.Be provided with power assistant spring 5 between the described interior seal casinghousing 21 in piston 3 and Electromagnetic Control mechanism 2.
Concrete working principle: when closed electromagnetic valve, motion bar 22 in the Electromagnetic Control mechanism 2 stops up through hole 33, water in the water inlet 12 constitutes in the cavity 4 from the interior seal casinghousing 21 that by-pass hole 34 flows into piston 3 and the Electromagnetic Control mechanism 2, then water on piston 3 area of contact greater than piston 3 area of contact with water inlet 12, the seal ring 32 of piston 3 resists the osculum 11 of valve body 1, when the pressure of intaking is very little, lean on the power of power assistant spring 5 to make piston 3 resist the osculum 11 of valve body 1; When solenoid valve is opened, move on the motion bar 22 in the Electromagnetic Control mechanism 2, make through hole 33 conductings, water in the water inlet 12 flows into from by-pass hole 34 in the cavity 4 of interior seal casinghousing 21 formations in piston 3 and the Electromagnetic Control mechanism 2, flow into osculum 11 again from through hole 33, because the diameter of through hole 33 is greater than the diameter of by-pass hole 34, then the hydraulic pressure on the top of piston 3 is less than the hydraulic pressure of piston 3 with the surface of contact of water inlet 12, move on the piston 3, make water inlet 12 and osculum 11 conductings.
Claims (2)
1, a kind of solenoid valve, but include valve body, be arranged on the Electromagnetic Control mechanism of valve body upper end, the piston of break-make valve body current also between valve body and Electromagnetic Control mechanism, interior seal casinghousing in this piston and the Electromagnetic Control mechanism constitutes a cavity, it is characterized in that: be provided with power assistant spring between the described interior seal casinghousing in piston and Electromagnetic Control mechanism.
2, solenoid valve according to claim 1, it is characterized in that: described piston is by support and be socketed on the support seal ring and form, offer through hole on the central position of described piston, this through hole cooperates with motion bar break-make in the Electromagnetic Control mechanism, described eccentric part at piston is provided with the by-pass hole that always is on state with the water inlet, and the diameter of this by-pass hole is slightly less than the diameter of through hole.
