Description
Technical field
The utility model belongs to the solenoid valve technical field, especially relates to a kind of combustion gas blowout protection solenoid valve.
Background technique
Solenoid valve is a kind of more common automation foundation original paper, belongs to final controlling element, and application is wider, has mechanical control field that daily life field is also arranged.Combustion gas blowout protection solenoid valve such as a kind of routine is installed in during use in the kitchen range air valve cavity, plays the effect of switch.As everyone knows, when the gas cooker accident extinguishing and people have little time to close gas valve, even also unknown when flame-out, be easy to cause the accident of gas leakage, people carry out the blowout protection of gas cooker through a solenoid valve that is connected with thermocouple for this reason.
Existing combustion gas blowout protection solenoid valve comprises parts such as guide sleeve, flange, valve seat, valve bonnet, spring, valve shaft and sealing gasket; Be provided with electrode in the described guide sleeve, be provided with moving iron core, static iron core, skeleton in the described valve bonnet and be wrapped in the outer coil of skeleton.
The working principle of existing combustion gas blowout protection solenoid valve can simply be interpreted as; When kitchen range burnt, the sealing gasket on the solenoid valve separated with fuel gas inlet place port, when kitchen range are flame-out; Automatically block fuel gas path, prevent that combustion gas from escaping, solenoid valve work is blocked fuel gas inlet through sealing gasket.
Valve bonnet on the combustion gas blowout protection solenoid valve of existing technology adopts the fit mode to be connected with valve seat, and promptly valve bonnet is enclosed within outside the valve seat, and the valve seat outer wall has an indent circle; The valve bonnet inwall is provided with a bulge loop that the cross section is curved; Be connected valve bonnet and valve seat based on bulge loop and matching of indent circle, but because the bulge loop cross section of valve bonnet inwall is curved, angle tilt; Break away from the indent circle easily, thereby it is unreliable to make that valve bonnet is connected with valve seat.
The model utility content
The technical problem that the utility model will solve is: provide a kind of valve bonnet to be connected combustion gas blowout protection solenoid valve more reliably with valve seat.
The technological scheme that the utility model is taked is: a kind of combustion gas blowout protection solenoid valve, and it comprises the valve seat that is set with valve bonnet, the other end of valve seat is with flange and guide sleeve; Be provided with the electrode that connects valve seat in the guide sleeve, be provided with the static iron core that is connected in valve seat in the valve bonnet, static iron core is with the skeleton that is twining coil outward; Also be provided with the moving iron core that is connected valve shaft one end in the valve bonnet; The other end of valve shaft connects a sealing gasket, and sealing gasket is positioned at outside the valve bonnet, is provided with a spring between sealing gasket and the valve bonnet end; Spring housing outside valve shaft, described valve bonnet and valve seat snapping.
Described valve bonnet and valve seat snapping are meant that valve bonnet mouth inwall is provided with a protruding circle; The valve seat outer wall is provided with and is used for the spacing interior scrobicular ring of living of protruding circle; Scrobicular ring comprises guide ring and limited ring in described, and the guide ring cross section is skewed, and limited ring longitudinal section and guide ring longitudinal section form a right angle barb.
The beneficial effect of the utility model is: valve bonnet and valve seat snapping on the utility model combustion gas blowout protection solenoid valve, and the snapping place adopts the right angle barb spacing as anti-disengaging, good anti-drop effect, valve bonnet is connected more reliable with valve seat.

Embodiment
Below be the utility model preferred embodiment, but therefore do not limit the protection domain of the utility model.
With reference to Fig. 1, Fig. 2 and shown in Figure 3, a kind of combustion gas blowout protection of the utility model solenoid valve, it comprises the valve seat 2 that is set with valve bonnet 1; The other end of valve seat 2 is with flange 3 and guide sleeve 4, is provided with the electrode that connects valve seat 2 in the guide sleeve 4, is provided with the static iron core 5 that is connected in valve seat 2 in the valve bonnet 1; Be with the skeleton 7 that is twining coil 6 outside the static iron core 5, also be provided with the moving iron core 9 that is connected valve shaft 8 one ends in the valve bonnet 1, the other end of valve shaft 8 connects a sealing gasket 10; Sealing gasket 10 is positioned at outside the valve bonnet 1; Be provided with a spring 11 between sealing gasket 10 and valve bonnet 1 end, spring 11 is enclosed within outside the valve shaft 8, described valve bonnet 1 and valve seat 2 snappings.
In conjunction with Fig. 2 and shown in Figure 3; Described valve bonnet 1 is meant that with valve seat 2 snappings 1 mouthful of inwall of valve bonnet is provided with a protruding circle 1.1; Valve seat 2 outer walls are provided with and are used for the spacing interior scrobicular ring of living of protruding circle 1.1; Scrobicular ring comprises guide ring 2.1 and limited ring 2.2 in described, and guide ring 2.1 cross sections are skewed, and limited ring 2.2 longitudinal sections and guide ring 2.1 longitudinal sections form a right angle barb.Protruding circle 1.1 card limits on the valve bonnet 1 of the utility model are in limited ring 2.2, and the right angle barb that limited ring 2.2 longitudinal sections and guide ring 2.1 longitudinal sections form is blocked, and can effectively avoid valve bonnet 1 to break away from.
