Abstract
The utility model relates to a filtering bottle with a vacuum control shutoff valve. The filtering bottle with the vacuum control shutoff valve is provided with a tapered bottle body which is narrow at the upper part and wide at the lower part, wherein a rubber plug with a jack in the middle is arranged at the upper end of the bottle body; an air extracting pipe extending outwards is arranged on the side surface of the bottle body; the air extracting pipe is connected with a vacuum pump; and the shutoff valve is arranged in the middle part of the air extracting pipe, and the lower end of a Buchner funnel which is internally provided with a filter net is tightly coincided and inserted with the rubber plug. The filtering bottle with the vacuum control shutoff valve can manually control on/off of the filtering bottle and the vacuum pump, but the vacuum pump does not need to work all the time, so electric energy is effectively saved, the service life of the vacuum pump is prolonged, and great convenience is brought for chemical experiments by people.
Description
Technical field
the utility model relates to a kind of bottle,suction, especially with the bottle,suction of vacuum control stop valve.
Background technology
are present; When in chemical test, using bottle,suction, need to keep vacuum in the bottle, so need bottle,suction be connected with vavuum pump always; And be engraved in work when keeping vavuum pump; Not only wasted electric energy, and reduced the service life of vavuum pump, done chemical experiment to people and make troubles.
The utility model content
are in order to solve the problem that existing bottle,suction need be communicated with vavuum pump in use constantly; The utility model provides a kind of bottle,suction with the vacuum control stop valve; The bottle,suction of this band vacuum control stop valve can the Artificial Control bottle,suction and being communicated with or disconnection of vavuum pump, does not need vavuum pump to work always, has effectively practiced thrift electric energy; Prolonged the service life of vavuum pump, done chemical experiment to people and bring very big facility.
the utility model solves the technical scheme that its technical problem adopted: the bottle,suction of this band vacuum control stop valve is provided with the bottle of a up-narrow and down-wide taper; The rubber stopper that has jack in the middle of the upper end of bottle is provided with; The side of bottle is provided with outwardly directed exhaust tube; Exhaust tube is connected with vavuum pump, and the middle part of exhaust tube is provided with stop valve, and inside has the lower end and the identical closely grafting of rubber stopper of the Buchner funnel of filter screen.When using bottle,suction, open stop valve earlier, use vavuum pump, close stop valve, from Buchner funnel, pour the trial target that needs then into the bottle,suction environment that is evacuated; After after a while, when no longer satisfying vacuum environment in the bottle,suction, only need open stop valve once more can be evacuated bottle,suction once more.
The beneficial effect of
the utility model is; The bottle,suction of this band vacuum control stop valve can the Artificial Control bottle,suction and being communicated with or disconnection of vavuum pump; Do not need vavuum pump to work always; Effectively practiced thrift electric energy, prolonged the service life of vavuum pump, done chemical experiment to people and bring very big facility.
