Abstract
The utility model relates to a self-locking safety valve for a hand carried steam cleaner, which comprises a sealing gasket, a pressure relief spring, an adjusting washer and a valve core. The utility model is characterized in that the adjusting washer which can integrally slide in a valve body up and down along with the valve core, the pressure relief spring and the sealing gasket are fixed in the valve core. A sealing ring is arranged between the valve core and the valve body. A U-shaped sealing ring is arranged outside the valve core. A spring is arranged between the valve core and a valve cap, and the upper part of the valve core is provided with a reset spring. A valve core pressing block which limits the slide distance of the valve core is installed outside the valve body, and screw threads on the upper part of the valve body are connected and fixed with the valve core pressing block. The lower part of the valve body is provided with screw threads which can be screwed onto a boiler. A safety valve cap and a valve sleeve are arranged between the valve core pressing block and the valve body and fixed by screws. The utility model can automatically realize the functions of self locking with pressure and steam unloading with high pressure.
Description
Technical field
The utility model relates to a kind of steam cleaner safety protection device, particularly hand-held cleaning steam machine self locking safety valve.
Background technique
At present, the safety valve of hand-held cleaning steam machine is made up of bonnet, valve body, sealing gasket, back lash spring, adjustment packing ring.When needs add water once more, open the safety-valve, add water, at this moment, remaining steam is arranged in boiler, will discharge suddenly, scald the operator.
The utility model content
Scald the operator for the steam that overcomes hand-held cleaning steam machine remnants, the utility model provides a kind of hand-held cleaning steam machine self locking safety valve, and this safety valve can not only have the high voltage protective effect, and the residual voltage self-locking action is arranged, the protection operator.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
Hand-held cleaning steam machine self locking safety valve, comprise valve body, sealing gasket, back lash spring, adjustment packing ring and spool, it is characterized in that: can be fixed in the spool with adjustment packing ring, back lash spring, the sealing gasket that spool integral body slides up and down in valve body, sealing gasket is provided with back lash spring, and the back lash spring overhead is adjusted packing ring.
Between described spool and the valve body seal ring is housed.
Described spool is adorned the U RunddichtringO outward.
One spring is contained between spool and the safe bonnet.
Described spool top is equiped with Returnning spring, and valve body is adorned the spool briquetting of restriction spool sliding distance outward.
Described valve body top screw thread and spool briquetting are connected and fixed, and valve body lower portion has the screw thread that can be screwed on the boiler, adorn safe bonnet and valve pocket between spool briquetting and the valve body, and safe bonnet and valve pocket are fixed with screw.
According to the utility model, when producing vapor pressure in the boiler, sealing gasket, back lash spring, adjustment packing ring upwards slide with spool is whole, and spool and spool briquetting break away from, and when rotating safe bonnet, it is motionless that valve body keeps, and realizes auto-lock function; When the boiler internal pressure increases to a certain degree, back lash spring is compressed, and moves on the sealing gasket, and the beginning release realizes the high voltage protective effect; When not having vapor pressure in the boiler, under action of reset spring, spool is whole to glide, and with the interlock of spool briquetting, when rotating safe bonnet, valve body rotates thereupon, can add water once more.
The beneficial effects of the utility model are that when the boiler of steam cleaner had pressure, safety valve can pin automatically, prevented to open by mistake safety valve, the protection operator.In the steam high voltage protective, the residual voltage auto-lock function is arranged, simple in structure, cost is low.
