Fig. 1 is the front view of the suction filtration device that provides among the utility model embodiment;
Fig. 2 is the left view of the suction filtration device that provides among the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of suction filtration device, this device comprises: the cavity 1 of aspiration pump (not shown), sealing, several valves that can open and close separately 2 and several are used for the pipeline that is connected with filtering flask, several valve 2 intervals are installed on the cavity 1, each valve 2 respectively connects a pipeline, and aspiration pump is by the internal communication of pipeline and cavity 1.
Particularly, valve 2 is set to the valve 2 that can open and close separately, can realize the suction filtration to the sample of different suction filtration time, after certain sample suction filtration is finished, the valve 2 that is connected with the filtering flask that this sample is housed can be closed, do not affect the suction filtration that other are not finished the sample of suction filtration, realized the working condition of a plurality of filtering flasks of flexible control.And by cavity 1 and valve 2, can distribute equably negative pressure and smooth gas circuit for each filtering flask, also for aspiration pump provides the negative pressure buffering, improve the life-span of aspiration pump.
More specifically, as shown in Figure 1, the number of the valve 2 of present embodiment is 5, but not as limit, the number of the valve 2 in the utility model can be according to concrete needs setting, and each valve 2 specifically be connected with aspiration pump or be connected with filtering flask also can be according to concrete needs setting.
Preferably, cavity 1 is circular cylindrical cavity.
Preferably, this pipeline is hard tube.Particularly, an end of hard tube is installed on the valve 2, and the other end of hard tube can directly cooperate with the rubber tube socket joint of aspiration pump or filtering flask.Adopt hard tube, in the time of can avoiding using flexible pipe, because the pressure of aspiration pump is excessive, when sample is finished suction filtration, if there is not timely valve-off, can cause the pipeline of flexible pipe glutinous together, cause the not smooth problem of gas circuit, guaranteed that the gas circuit of whole suction filtration device is unobstructed.
