Description
Technical field
The utility model belongs to soil test field, more particularly to a kind of saturation device to soil sample automatic vacuum.
Background technology
Indoors in soil test, the size of native saturation degree is to follow-up permeability test, consolidation test and shearing test
Result Deng experiment will produce large effect.Sample vacuum suction saturation is usually that the soil sample prepared is loaded saturator
Vacuum saturation cylinder is built in, vacuum air pump and vacuum saturation cylinder are connected, air inlet is closed, starts air exhauster, pneumatics of taking seriously
Power reaches an atmospheric pressure value（When pumpdown time is small no less than 1）, extraction valve is closed, stops pumping, water inlet pipe is opened, makes steaming
In the sample of distilled water injection vacuum saturation cylinder, treat that the water surface exceedes soil sample saturator and completes vacuum.At present, be evacuated timing and
The actions such as pumping shutdown are required for manually carrying out.
The content of the invention
The purpose of this utility model is a kind of automation pumping saturation device of design, pumping the injecting process is realized automatic
Change, you can remove the action such as timing, controlled valve from, sample is taken away after waiting sample immersion fully saturated, it is more convenient
Simply.
The utility model is realized in this way：One kind automation pumping saturation device, by check (non-return) valve, vacuum meter, normally opened electricity
Magnet valve door, vacuum pumping pump, distilled water water storage barrel, exhaust tube, water inlet pipe, vacuum barrel sealing cover, vacuum barrel, water inlet extension tube, Sheng
Put sample liner and timing means composition.
Vacuum barrel sealing cover top is respectively equipped with pressure-detecting device i.e. vacuum meter and the unidirectional exhaust tube of check (non-return) valve control,
The exhaust tube other end is connected with vacuum pumping pump；One end of normally open solenoid valve door and the water inlet extension tube phase through vacuum barrel sealing cover
Even, the other end of normally open solenoid valve door is connected with water inlet pipe, in water inlet pipe other end insertion distilled water water storage barrel；Inside vacuum barrel
Sample liner is held, vacuum pumping pump passes through circuit connected in series with timing means and normally open solenoid valve door；Hold sample liner and
Distilled water water storage barrel has volume scale.
The present apparatus can be in the case of unattended, and air exhauster is closed in timing, and completion automatically opens up inlet valve and completes to discharge water
The action of soil sample is soaked, test efficiency can be effectively improved, the plastic inner container that increase holds sample can be prevented in immersion containing corrosion
During the sample of property, liquid corrosion vacuum barrel.
Compared with prior art, the benefit effect of the utility model is that the utility model can realize automation mechanized operation, convenient
Simply, its device is easy to implement.
