1）The method for being gone to balance unknown pressure with known pressure, to measure the instrument of pressure, such as jet method is measured. 2）Use flexible member
The elastic force and measured medium active force method that balances each other measure the instrument of pressure, such as bourdon gauges. 3）With
Pressure signal is converted into the method for electricity to measure the electrical distance transmitting manometer of pressure, such as pressure by mechanically and electrically element
Become into device etc..
Liquid Column Manometer is based on hydrostatics principle, when the linker side for filling known liquid is pressurized
Afterwards, liquid can produce liquid-column height corresponding with pressure in the opposite side of linker, just be known by the height for calculating known fluid column
Road pressure size.It has certain limitation, and the pressure of measurement can not be too big, usually minute-pressure, and working solution
Density can with environment temperature change, its volume can also change, and should be corrected in actually measurement.If working solution is solidifying
Solid point is higher, it should be noted that insulation in maintenance repair；Flexible type pressure gauge is the elasticity produced by after being pressurized based on flexible member
It is deformed into Fundamentals of Measurement work.When flexible member stress, to the size of stress, it may occur that certain deformation, pass through manufacture
Technique, using material and demarcation, it is known that its corresponding pressure limit, so as to measure unknown pressure.Its maintenance should be by mark
Quasi- periodic inspection, main contents have：1. greasy dirt inside and outside table is removed；2. check whether there is blocking at pressure tapping；3. transmission is checked
Position gear structure；4. lubricating oil is added to partial turn position；5. calibrated according to verification code；Electrical distance transmitting manometer is
Pressure signal is converted into electric signal, and by signal teletransmission to the instrument indicated elsewhere.With the development of automatic technology,
Such instrument species model is various, and no movable member is substantially all to new electrical distance transmitting pressure transmitter, and its measuring cell is
Bellows-type structure, the Displacement-deformation for there was only very little during measurement, in pressure allowed band, it is free from corrosion in the case of, the feelings of damage
Seldom, amplifier section is solid state electrical circuit to condition.
The instrument species of in the market measurement pressure is various, and many instruments are due to vdiverse in function, such as：Electronic universal tester,
Corresponding cost is also costly, and the experiment that simply measures is only needed to for some, purchase so expensive instrument, it is clear that have not
Appropriate part.
Utility model content
The purpose of this utility model is to provide a kind of use for laboratory in the device of measurement porous ceramic grain pressure, and the device leads to
Cross with the movement or increase counterweight focused on rail plate and change different briquettings, it is possible to achieve different weight, shape
Sample measurement.
Technical solution：
A kind of use for laboratory is including base, fixing support rack, scale bar, removable in the device of measurement porous ceramic grain pressure
Dynamic support frame, it is characterized in that：Fixing support rack is vertically fixed on one end of base, scale club body and set along shaft length direction
There are length metering scale, the front end of scale bar and the top hinge connection of fixing support rack, in the lower section connection that scale bar is anterior
There is briquetting connecting rod, the bottom of briquetting connecting rod is connected with briquetting, along shaft length direction provided with cunning on scale club body
Counterweight is slidably connected on dynamic guide rail, rail plate.
Scale on the scale bar is accurate to a millimeter rank.
The briquetting is to be threadedly coupled with briquetting connecting rod, when measuring sample of different shapes, can be changed different
Briquetting.
The utility model has the advantages that：Scale bar is designed to rotatable hinge connection shape by device of the present utility model
Formula, on the premise of use requirement is met, convenience simple in construction；Device of the present utility model is designed to briquetting by being threadedly coupled
Replaceable form, can need to change various forms of briquettings with experimental, can not only carry out the pressure measxurement of spheroid,
Aliquot can also be carried out indirectly（Such as cuboid）Ionization meter, while also having wider application；
Counterbalance design into that can be slided on guide rail and can increase the form of weight, is not only expanded survey by device of the present utility model
Scope is measured, the service efficiency of the device is also improved；Whole operation process is easily understood device of the present utility model when in use,
Apparatus structure volume is small, and easy to operate and repeatable strong, the pressure measxurement for the simple sample in laboratory more meets economy
Requirement.

Embodiment
Referring to the drawings, the utility model includes base 1, fixing support rack 2, scale bar 8, removable support frame 10, fixed
Support frame is vertically fixed on one end of base, scale club body along shaft length direction and is provided with length metering scale, scale bar
On scale be accurate to a millimeter rank, the front end of scale bar and the hinge connection of hinge axis 3 of the top of fixing support rack so that carve
Degree bar can realize 0 ~ 45 ° of rotation in operation；The anterior lower section of scale bar is connected with briquetting connecting rod 5, briquetting connecting rod
End thread is connected with briquetting 4, when measuring sample of different shapes, can change different briquettings.On scale club body
It is provided with along shaft length direction on rail plate 9, rail plate and slidably connects counterweight 7.Removable support frame 10 is arranged on bottom
Between seat and scale bar afterbody, for supporting scale bar, movable supporting frame 10 is removed when testing.
The use process of the utility model device：, will be with powder after screening by a kind of method of coal ash for manufacturing for haydite
Coal ash is put into wet-milling in ball mill for the mixture of primary raw material and mixes to form mixing mud；Granulated with comminutor, then by particle
It is put into alumina crucible, is placed in taking out after sintering and natural cooling in resistance furnace.If the haydite after cooling is selected at random
Dry doubling is numbered, and before measuring first removes removable support frame 10, haydite is sequentially placed into pressure resistant vessel 6 in order
Row measurement.When insufficient pressure, following two methods can be selected：（1）The position of counterweight 7 is adjusted on rail plate 9；（2）
Increase the weight of counterweight 7；Ordinary circumstance is first to adjust the position of counterweight, counterweight can be moved left and right according to rail plate increasing or
Reduce the pressure of briquetting, the wherein regulation of balance position needs uniformly to adjust at a slow speed, reduces operating error as far as possible, in order to avoid pressure mistake
Big moment crushing haydite；If it is not possible, the weight of appropriate increase counterweight again, the increase of counterweight will also avoid disposable addition
Cross weight.Until haydite is crushed, the pressure that haydite can bear then is conversed according to the scale value on scale bar, immediately
And removable support frame 10 is put into Support Position, further take out style；The experimental result of gained is analyzed, cast out error compared with
Big numerical value, then average.If specimen shape is different, the briquetting matched can be changed and tested, meet experiment
It is required that in the case of, make more convenient operation, while have also been enlarged the use scope of the device, improve the service efficiency of device.
