Abstract
The utility model belongs to the technical field of valves, and in particular relates to an electromagnetic valve with a manual control function. The electromagnetic valve can be applied to the field of fluid automatic control. The electromagnetic valve comprises an electromagnetic control section and a manual control section, wherein the manual control section comprises a valve body lining piece, an O-shaped ring, a sealing ring, a manual rotor seat, a manual rotor and a manual protecting cover. The lining piece is arranged below the manual rotor which is in sealing connection with the manual rotor seat through the O-shaped ring, and the manual rotor seat is in sealing connection with a valve body through the sealing ring. The manual protecting cover is sleeved on the position above the manual rotor seat, and a pressure-relieving through hole is arranged between a cavity A of the electromagnetic valve body and a cavity B of the electromagnetic valve body. When the power-supply failure of an electromagnetic valve circuit occurs or an electromagnetic coil can not be opened due to self-failure, the pressure-relieving through hole between the cavity A and the cavity B of the valve body can be opened through a manual method, accordingly the pressure in the cavity A of the electromagnetic valve is changed so as to enable the electromagnetic valve to be opened. After the improvement, the electromagnetic valves are simple in structure, and convenient to produce and replace.
Description
One, affiliated technical field:
The utility model belongs to valve technology field, is particularly useful for relating to a kind of electromagnetic valve device with manual control of fluid automation field.
Two, background technique:
Current, just in fields such as solar water heater, be extensive use of to the defeated automatic controller of high water level container for fluid.Electric valve such as electromagnetism, motor is the crucial power unit in the automatic controller.But electromagnetic valve in use because problems such as fault or electromagnetic coil can't normally be opened, causes solenoid valve proper functioning as requested.Bring inconvenience to the user.A kind of solenoid valve good product performance that the utility model provides with manual control, easy and safe to operate reliable, sealability is high, simple in structure, volume is little, cost is low.
Three, summary of the invention:
Task of the present utility model is can not reliably open at the electromagnetic valve circuit fault, and practical problem that can't moisturizing provides a kind of solenoid valve product with manual control.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of solenoid valve with manual control, solenoid valve comprises Electromagnetic Control and manually controls two parts, wherein manual control part is by the valve body liner, O type circle, seal ring, manual rotator seat, manual rotor, manually protecting cover is formed, liner is positioned at the below of manual rotor, manually rotor is tightly connected by O type circle with manual rotator seat, manually rotator seat and valve body are tightly connected by seal ring, manually the top of rotator seat is with manual protecting cover, and design has a pressure release through hole between electromagnetic valve body A chamber to B chamber.
The main structure principle is that design has a pressure release through hole between electromagnetic valve body A chamber to B chamber.The pressure release through hole is in closed condition under the normal condition, and according to getting electric or dead electricity situation realization control automatically, solenoid valve is in normal working state by electromagnetic coil in the opening and closing of solenoid valve.In case when electromagnetic valve circuit power supply trouble or electromagnetic coil faults itself occur and can't open, pressure release through hole between valve A chamber to the B chamber is opened, cause solenoid valve A cavity pressure to change, impel electromagnetic valve to open.It is simple in structure to improve the back, is convenient to produce and exchange.
Four, description of drawings:
Fig. 1 is the manually electromagnetic valve structure figure of control of band;
Fig. 2 is manual control part closed condition figure;
Fig. 3 is manual control part opening state figure.
Five, embodiment:
Below in conjunction with embodiment and accompanying drawing to the utility model and effect thereof again description.
With reference to figure 1-3, a kind of solenoid valve with manual control, this solenoid valve comprise Electromagnetic Control part and manual control part, and manual control section is mainly by liner 1, O type circle 2,4, seal ring 3, manual rotator seat 5, manually rotor 6 and manually protecting cover 7 form.Liner 1 is positioned at the below of manual rotor 6, manually rotor 6 is connected by O type circle sealing 2,4 with manual rotator seat 5, manually rotator seat 5 is tightly connected by seal ring 3 with valve body, and manually the top of rotator seat 5 is with manual protecting cover 7, and design has a pressure release through hole between electromagnetic valve body A chamber to B chamber.The hand-control device of solenoid valve is in the normal position under Fig. 2 normal condition, because the functional vias of liner 1 is in closed condition.According to getting electric or dead electricity situation realization control automatically, solenoid valve is in normal working state by electromagnetic coil in the opening and closing of solenoid valve.Fig. 3 is when power supply trouble or electromagnetic coil faults itself appear in electromagnetic valve circuit can't open the time, can the liner in the B chamber be opened by the method for the manual rotor 6 of manual tune, make the pressure release through hole UNICOM between solenoid valve A chamber to the B chamber, cause the valve A cavity pressure to change and solenoid valve is opened.
Claims (1)
1. be with the manually solenoid valve of control for one kind, comprise Electromagnetic Control and manually control two parts, it is characterized in that: manual control part is made up of valve body liner, O type circle, seal ring, manual rotator seat, manual rotor, manual protecting cover, wherein liner is positioned at the below of manual rotor, manually rotor is tightly connected by O type circle with manual rotator seat, manually rotator seat and valve body are tightly connected by seal ring, manually the top of rotator seat is with manual protecting cover, and design has a pressure release through hole between electromagnetic valve body A chamber to B chamber.
