Description

A kind of solenoid valve

Technical field

The utility model belongs to Solenoid Valve Technology field, refers in particular to a kind of solenoid valve for field of fluid control.

Background technique

Solenoid valve is final controlling element important in automation field, as the solenoid valve in the automatic water controller such as solar water heater, air-source water heater.At present, the hydraulic pressure of water tank, water tower height is the impact existing solenoid valve effect of intaking directly, particularly at water tank or water tower hydraulic pressure is low, water level is low, existing solenoid valve is when opening, flow is little, not water outlet sometimes, cannot carry out normal water supply to watering equipment.

Summary of the invention

The purpose of this utility model is a kind of solenoid valve, and it normally can work in low hydraulic pressure, low water level situation, can ensure watering equipment normal water supply, and can not affect by external condition.

For achieving the above object, the solution that the utility model is taked is: a kind of solenoid valve, it comprises valve body, diaphragm, be provided with flap and the solenoid electromagnetic controller of relief hole, extension spring one connects the fixed ring column on iron core, other end connects the traction annulated column on flap, diaphragm is clamped under flap, said structure composition one is placed in valve body, primary valve is provided with in valve body, iron core places return spring, mounting and solenoid electromagnetic controller, valve body is inserted in mounting bottom, return spring inserts in mounting, return spring one end contacts with iron core, the other end contacts with mounting, solenoid electromagnetic controller is inserted on mounting top, solenoid electromagnetic controller is fixed on valve body.

This kind of solenoid valve normally can work under 0-0.8MPa hydraulic pressure, can ensure watering equipment normal water supply, and can not affect by external condition.

Fig. 2 is the plan shape figure of the present embodiment.

Fig. 3 is iron core and the flap connection diagram of the present embodiment.

In figure: 1, solenoid electromagnetic controller, 2, mounting, 3, return spring, 4, iron core, 5, plug, 6, extension spring, 7, flap, 8, diaphragm, 9, valve body, 10, primary valve, 11, fixed ring column, 12, traction annulated column.

Embodiment

Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described again.

See Fig. 1-Fig. 3, a kind of solenoid valve, it comprises valve body 9, diaphragm 8, be provided with flap 7 and the solenoid electromagnetic controller 1 of relief hole, extension spring 6 one connects the fixed ring column 11 on iron core 4, other end connects the traction annulated column 12 on flap 7, flap clamps diaphragm 87 times, said structure composition one is placed in valve body 9, primary valve 10 is provided with in valve body 9, iron core 4 is placed return spring 3, mounting 2 and solenoid electromagnetic controller 1, valve body 9 is inserted in mounting 2 bottom, return spring 3 inserts in mounting 2, return spring one end contacts with iron core 4, the other end contacts with mounting 2, solenoid electromagnetic controller 1 is inserted on mounting 2 top, solenoid electromagnetic controller 1 is fixed on valve body 9.

See Fig. 1 and Fig. 3, described iron core 4 has plug 5, is beneficial to shutoff relief hole better.

See Fig. 1 and Fig. 3, its working principle is: after solenoid electromagnetic controller 1 switches on power, iron core 4, under the effect of magnetic force, is sucked up, and opens relief hole, valve starts pressure release, hydraulic pressure now on flap 7 reduces, link into an integrated entity because iron core 4 and flap 7 have been pulled spring 6, iron core 4 also pull-up flap 7 while being sucked up under the effect of magnetic force, open the primary valve 10 in valve body 9, water can pass through fast.After solenoid electromagnetic controller 1 is de-energized, under return spring 3 acts on, plug 5 seals the relief hole in flap 7, the hydraulic pressure on flap 7 is raised, the primary valve 10 in valve body 9, and stops water flowing (water supply).
