Description
Technical field
The utility model relates to a kind of through type manometer, and this pressure is counted the instrument of measuring various fluids, and can send main control system to by this pressure signal, to reach the purpose of measurement, record and controlled pressure parameter.
Background technology
Pressure gauge can be divided into fluid column formula, flexible type and 3 kinds of forms of sensor type according to the principle of work difference.Fluid column formula such as U type pipe pressure meter, comb pressure gauge etc. are to change pressure signal into the liquid-column height signal according to the hydrostatics principle, often make water, alcohol or mercury as pressure measurement working medium.The liquid column pressure meter is simple in structure, and sensitivity and degree of accuracy are all high, is usually used in proofreading and correct the other types pressure gauge, and shortcoming is that volume is big, reaction is slow, is difficult to automatic measurement.Flexible type such as bourdon's tube pressure gauge change pressure signal the mechanically deform amount of flexible member into, export signal with the mode of needle deflection.The flexible type pressure gauge is easy to use, the pressure measurement scope is big, but precision is lower, can not measure automatically equally.
For this reason, design the automatic accurate measuring fluid pressure of a kind of ability, the pressure gauge of especially measuring the easy condensable fluid pressure of variable concentrations is necessary.
Summary of the invention
The purpose of the utility model is a kind of through type manometer of design, can accurately with fast measure, and outstanding energy measurement dynamic pressure is measured the pressure gauge that variable concentrations is prone to condensable fluid pressure.
The technical scheme of the utility model: the through type manometer of the utility model comprises housing, stock inlet, grout outlet, pressure unit; Housing is cylindrical, and two ends are respectively stock inlet, grout outlet, and the column leather hose is installed in the cavity between stock inlet and grout outlet; The two ends of column leather hose and housing inner chamber sealed at both ends; There are in the middle of the housing oil hole and housing to communicate, fill with oil in the oil pocket, on housing, have instrument connection to be communicated with oil pocket with oil pocket between the column leather hose; Pressure unit is installed on the housing, the sensor alignment instrument connection of pressure unit.
The inner chamber of described housing is the cydariform that broad in the middle being convenient to small in ends forms oil pocket.
The two ends of described column leather hose have sealing ring, and the sealing ring at column leather hose two ends is embedded in the closure gasket groove of housing, and detected fluid and oil pocket are separated.
Described column leather hose is the rubber leather hose, and the wall thickness of column leather hose is 1mm.
Described pressure unit outer has the waterproof sealing cover, and the waterproof sealing cover is connected on the housing.
Described pressure unit adopts a kind of diffused silicon pressure transmitter.
The advantage of the utility model: the through type manometer of the utility model adopts the column leather hose of unique design, and the sealing ring of this leather hose and two ends design forms natural oil pocket, realizes the slurry oil isolation, practices thrift manufacturing cost; The column rubber leather hose of the utility model has the acid and alkali-resistance characteristic, good springiness, and the influence that solidified by the high concentration fluid is very little; The unique design column leather hose that the utility model adopts is that straight line is through, also is difficult for stopping up even be prone to condensable fluid; The through type manometer of the utility model adopts the pressure unit with high reliability amplifying circuit
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Fig. 1 is the structural representation of the utility model: the through type manometer of the utility model comprises housing 1; Housing 1 is cylindrical, and two ends are respectively stock inlet 8, grout outlet 9, and column leather hose 2 is installed in the cavity between stock inlet 8 and grout outlet 9; The two ends of column leather hose 2 and housing 1 inner chamber sealed at both ends; In the middle of housing 1, there are oil hole 7 and housing 1 to communicate, fill with oil in the oil pocket 4, on housing 1, have instrument connection 5 to be communicated with oil pocket 4 with oil pocket 4 between the column leather hose 2; Pressure unit 6 is installed on the housing 1, the sensor alignment instrument connection 5 of pressure unit 6.
The inner chamber of described housing 1 is cydariform the best that broad in the middle being convenient to small in ends forms oil pocket 4.
The two ends of described column leather hose 2 have sealing ring 3, and the sealing ring 3 at column leather hose 2 two ends is embedded in the closure gasket groove of housing 1, and detected fluid and oil pocket 4 are separated.
Described column leather hose 2 is rubber leather hoses, and the wall thickness of column leather hose 2 is 1mm.
Described pressure unit 6 outer has waterproof sealing cover 10, and waterproof sealing cover 10 is connected on the housing 1.
The stock inlet of the utility model, grout outlet and column leather hose form direct piping, and detected fluid can be passed through from this direct piping.Column leather hose two ends are designed with sealing ring, and sealing ring is isolated with the oil pocket between housing 1 and the column leather hose 24 and with column leather hose inner chamber, promptly realizes the slurry oil isolation; The column leather hose of fluid from stock inlet from stock inlet is through direct piping, and extruding column leather hose is full of oil in the oil pocket 4; When the column leather hose is extruded; Wet goods value in the oil pocket 4 is transmitted the sensor that pressure is given pressure unit 6, when sensor receives stress, because the variation of carrier mobility; Its resistivity is changed, thereby convert mechanical quantity to electric signal.The output electric signal of transmitter is linear with the pressure that acts on the pressure transducer.The 0-10MPa pressure that will be in the milk during pressure gauge work converts the 4-20mA electric signal to through pressure transducer and supporting amplifying circuit and sends into main frame, thereby realizes accurate and quick gaging pressure parameter.Pressure gauge adopts the KYB2003 pressure unit; This pressure unit is introduced a kind of novel diffused silicon pressure transmitter of external MEMS state-of-the-art technology cooperation research and development; Adopt the isolated sensing assembly of U.S.'s import diffuse si; Through the amplifying circuit of high reliability, convert gauge pressure or absolute pressure into the standard electric signal.
The core of the utility model is to adopt the column leather hose to transmit pressure, and therefore, every employing leather hose deformation drives the pressure gauge that the interior liquid motion of oil pocket produces piezoresistive effect, all belongs to the protection domain of the utility model.
