Description
Technical field
The present invention relates to the measurement of volume, it is especially a kind of using pressure gage come the volume of rapid survey irregularly shaped object
Device.
Technical background
The current common method of the cubing of irregularly shaped object is spilling water method or excessive micromicrofarad to measure, and this method will allow
Object contacts water or contact is husky, and it is more troublesome to operate.And when certain valuables can not meet water, this measurement
Method is just not easy to carry out.Therefore it is directed to cubing, the density measure (mass/volume) etc. of irregular-shaped objects, at present
It there is no a more mature method or product.
Summary of the invention
For the volume for measuring object, especially the volume of specification object, the present invention do not design a kind of measurement irregularly shaped object
The device and method of volume.
The present invention realizes that the technical solution of goal of the invention is: a kind of device measuring irregularly shaped object volume, including one
Inside is the container of hollow cylinder, it is characterized in that: there is the sealing cover that can be dismantled on the left of a container, the center of sealing cover has
Venthole, venthole have the sealing device that can be dismantled, and test pallet, the top connection of container inside are arranged at the bottom of container inside
Pressure gage, container are transparent outer cover, there is volume markings on the outside of shell of tank, and there is a piston on the right side inside container, piston it is outer
Side center is fixedly connected with a pull rod.
A method of measurement irregularly shaped object volume is the container of hollow cylinder including an inside, it is characterized in that: holding
Test pallet is arranged at the bottom inside device, object under test is placed on test pallet, then the sealing cover in the left side of sealing container, close
There is venthole at the center of capping；The top of container inside is connected to pressure gage, and container is transparent outer cover, has body on the outside of shell of tank
Scale is accumulated, there is piston on the right side inside container, and the outer side center of piston is fixedly connected with a pull rod；Push the pull rod of piston to body
Product graduation mark V1, sealing ventilation hole record pressure P1 and volume markings line V1；Push the pull rod of piston to volume markings line again
V2 records corresponding pressure P2；If the volume of object under test is Vx；Estimate according to equation for ideal gases, ignores piston and be moved through
The variation of container internal temperature in journey, then P1*(V1-Vx)=P2* (V2-Vx), Vx=(P1*V1- P2*V2)/(P1-P2).
The beneficial effects of the present invention are: the volume or density of energy rapid survey irregularly shaped object.
Detailed description of the invention
Fig. 1 is measuring device schematic diagram；
Wherein, 1: test pallet；2: venthole；3: pressure gage；4: piston；5: pull rod；6: volume markings.
Specific embodiment
A kind of device measuring irregularly shaped object volume is the container of hollow cylinder including an inside, it is characterized in that: one
There is the sealing cover that can be dismantled on the left of a container, there is venthole 2 at the center of sealing cover, and venthole 2 has the sealing that can be dismantled
Test pallet 1 is arranged at device, the bottom of container inside, and the top of container inside is connected to pressure gage 3, and container is transparent outer cover, container
There are volume markings 6 on the outside of shell, there is piston 4 on the right side inside container, and the outer side center of piston 4 is fixedly connected with a pull rod 5.
A method of measurement irregularly shaped object volume is the container of hollow cylinder including an inside, it is characterized in that: holding
Test pallet 1 is arranged at the bottom inside device, object under test is placed on test pallet 1, then the sealing cover in the left side of sealing container,
There is venthole 2 at the center of sealing cover；The top of container inside is connected to pressure gage 3, and container is transparent outer cover, the outside of shell of tank
There are volume markings 6, there is piston 4 on the right side inside container, and the outer side center of piston 4 is fixedly connected with a pull rod 5；Push piston 4
Pull rod to volume markings line V1, sealing ventilation hole 2 records the atmospheric pressure pressure of the locality pressure P1() and volume markings line V1
(ignoring the variation of 2 bring pressure and volume of sealing ventilation hole, that is, ignore the volume of the sealing cover of venthole 2)；Work is pushed again
The pull rod of plug 4 can be greater than V1 to volume markings line V2(V2, and V2 can be less than V1), record corresponding pressure P2；If determinand
The volume of body is Vx；Estimate according to equation for ideal gases, the variation for ignoring container internal temperature in 4 moving process of piston is (i.e. living
The speed for filling in movement is slow, and the gas inside container sufficiently can carry out heat with the external world and exchange；Or the heat transfer effect of container
Rate is higher；Or until pressure value stablize it is constant after record P2), then P1*(V1-Vx)=P2* (V2-Vx), Vx=(P1*V1-
P2*V2)/(P1-P2).
