Abstract

The utility model discloses an electromagnetic valve for a combustion gas flameout protection. The electromagnetic valve comprises a valve main body, sealing gaskets, springs and a rubber rings, wherein the valve main body comprises valve shafts, valve sleeves which are sleeved in the middle parts of the valve shafts and a valve seat which is buckled between the bottoms of the valve sleeves; the tops of the valve shafts are provided with the sealing gaskets, the lower portions of the sealing gaskets are provided with spring seats, the spring seats are fixed on the outsides of the valve sleeves through the springs, the bottoms of the valve shafts are provided with moving iron cores, the insides of the valve shafts are provided with static iron cores and coils sleeved on the static iron cores, and the moving iron cores and the static iron cores can contact with each other; an electrode is disposed in the valve seat; a spire pad is disposed on the electrode; the rubber rings are sleeved on the external portion of the valve seat, the outside of the valve seat is invaginated; the sealing gaskets are sleeved in the invagination; and the sealing gaskets can swing about 10 degrees up and down. The connecting parts of each component are more stable, and a safety factor is increased, allowing the electromagnetic valve to be sucked and closed more sensitively.

Description

A kind of combustion gas blowout protection solenoid valve

Technical field

The utility model relates to a kind of solenoid valve, relates in particular to a kind of combustion gas blowout protection solenoid valve.

Background technique

Solenoid valve is the automation foundation element that is used for controlling flow direction, belongs to final controlling element; Be used for machinery control and above the industrial valve, also be usually used in the daily life.Such as; The solenoid valve of installing in the gas cooker has just played the effect of switch.Yet the solenoid valve of gas cooker in the market is when temperature raises, and some connected elements of solenoid valve come off easily, shown in Fig. 3 a; Because valve bonnet 207 is not to fit like a glove with valve seat 203; Thereby after the long-term use of gas cooker, have certain potential safety hazard, and shown in Fig. 2 a; Sealing gasket 211 is embedded between spring pad 210 and the valve shaft 208, has influenced the sensitivity of solenoid valve adhesive.

Summary of the invention

To above-mentioned technological deficiency; The utility model proposes a kind of combustion gas blowout protection solenoid valve; Through in original design, improving; Overcome solenoid valve when temperature raises, the problem that connected element comes off easily and through designing the position of sealing gasket and spring seat again makes solenoid valve adhesive sensitivity more.

In order to solve the problems of the technologies described above, the technological scheme of the utility model is following:

A kind of combustion gas blowout protection solenoid valve comprises valve body, sealing gasket, spring and rubber ring, and said valve body comprises valve shaft, is set in the valve pocket at said valve shaft middle part and is buckled in the valve seat between the said valve pocket bottom; Said valve shaft top is embedded with sealing gasket, and said sealing gasket bottom is provided with spring seat, and said spring seat is fixed on the said valve pocket outside through said spring; Said valve shaft bottom is provided with moving iron core, and said valve pocket inside also is provided with static iron core and snare is located at the coil on the iron core, and said moving iron core and said static iron core can be in contact with one another; Be provided with electrode in the said valve seat; On said electrode, be provided with the pinnacle plain cushion, said valve seat outer cover is provided with rubber ring, caves in the said spring seat outside; Said sealing gasket is sheathed in said the caving in, and said sealing gasket can be done 10 degree up and down and swing.

Further; Said valve pocket bottom is provided with convex parts; Said valve seat and said valve pocket joint are provided with breach, adopt the horizontal plane contact between said convex parts top and the said breach, and said convex parts is through withholding fixing said valve pocket of said breach and said valve seat.

The beneficial effect of the utility model is: through the improvement of technique scheme; Make that the attachment portion of each parts is more stable, prolonged the working life of gas cooker, improved safety coefficient; Through designing the position of sealing gasket and spring seat again, make the solenoid valve adhesive sensitive more.
