Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 2, the utility model provides a kind of bidirectional non-return valve, comprise upper internal cones 9 and lower internal cones 10 that vertical placement and counterpart connect, upward the upper/lower terminal of internal cones 9 and lower internal cones 10 is respectively arranged with connection mouth, and internal cones 9 and lower internal cones 10 inside are provided with hollow float 11 on this.
In the utility model, upper and lower inner conical surface and hollow float 11 all can form the complete potted line of a circle; The size and the thickness that need choose reasonable hollow float 11 can float in processed oil, liquid and come and have enough strength to seal potted line.
Bidirectional non-return valve of the present utility model utilizes hollow float 11 in the middle of upper and lower internal cones 9,10, cuts off respectively the passage of two media in position, whereabouts and floating position.This bidirectional non-return valve is spacer medium reliably, the problem of intaking in the easy oil when easily running oily problem and vacuum pump failure in the time of therefore can avoiding oil drain pump fault in the prior art when it is applied to the vacuum oil-filter system.
As shown in Figure 2, for convenience and the soundness of installing, bidirectional non-return valve of the present utility model can also comprise cylindrical shell 12, and upper internal cones 9 and lower internal cones 10 are installed in this cylindrical shell 12.The Placement of upper and lower internal cones can be flange-type, also can be clamp band type, can also be welding type.Preferably, can be provided with overhead gage 13 and lower pedal 14 on the cylindrical shell 12.The hollow float 11 preferred corrosion-resistant metal materials that adopt are made, and can guarantee that like this it has enough intensity, can guarantee that also sealing is reliable.
As shown in Figure 3, the utility model also provides a kind of vacuum oil-filter system with above-mentioned bidirectional non-return valve, comprise degassing tank 1, the filler opening of degassing tank 1 is connected with electric heater, the air outlet of degassing tank 1 connects carbonated drink separator box 3 through vacuum pump 2, the oil outlet of degassing tank 1 connects oil drain pump 4, wherein:
