Description
Technical field
The utility model relates to a kind of liquid level gauge, particularly a kind of magnetostriction liquidometer.
Background technology
The industrial basin that often utilizes is handled or storaging liquid now, for strict controlling liquid liquid level scope, generally all liquid level gauge can be installed.
Most of liquid level gauges are in the cavity or surveying instrument of the liquid and the operating conditions of inside being guided to the tank body outside by a series of pipeline that is tightly connected, in measuring liquid level such as jar external application floating drum differential pressure liquid level gauges.Because these liquid level gauges are to operate outside jar, be subjected to the influence of external environment easily, can not be like clockwork the built-in function environment of tank body be copied to the tank body outside, cause measurement result inaccurate, particularly when the operating temperature difference in environment temperature and the jar reached more than 50 ℃, error was obvious especially.
Commonly used at present having is a kind of at the direct magnetostriction liquidometer of measuring of tank interior, it comprises that there is the float of magnet an inside, float has center pit, a sealing feeler lever passes from the float center, float can slide on feeler lever, there is a transmitter gauge outfit on the feeler lever top, and the magnetostriction line is arranged in the feeler lever, and the magnetostriction line links to each other with piezoelectric sensor in the transmitter gauge outfit.Float is directly put in the jar from the flange opening part of tank deck together with a part of feeler lever, and float slides up and down along feeler lever with the rise and fall of liquid level in the tank body.The transmitter gauge outfit is sent current impulse, claim initial pulse, this pulse is propagated down along the magnetostriction alignment, in the process that moves downward, produce a magnetic field, meet and interact with the magnetic field that float produces, produce a torsional wave on the magnetostriction line, the piezoelectric sensor of transmitter gauge outfit changes into one with the torsional wave that records and returns pulse, convert the mistiming of returning between pulse and the initial pulse to pulse signal, thereby calculate the physical location of float.
The shortcoming of this device is a float, and the floater processing skill difficulty that has center pit is big.This center pit must be enough big so that and the feeler lever external diameter be complementary, therefore, float is had to by the diameter that increases himself or length to obtain the buoyancy of needs, it is than the float weight that does not have center pit.And the float of band center pit has increased corresponding weld seam, wants high with respect to the failure rate of the float that does not have center pit.Simultaneously the endoporus of float also may be stopped up by the impurity in the liquid, hinder its motion, at this moment needs to stop work to pull down liquid level gauge and clear up and could continue operate as normal.
The application of this liquid level gauge in the flash distillation process tank is also very undesirable.Comprise gas-liquid two-phase fluid in the flash distillation process tank, under set pressure, be easy to take place flass, cause turbulent flow at steam or liquid surface, cause the instability of liquid level, because float directly contacts the liquid of fluctuation in the tank body, float will fluctuate with liquid level, can't accurately learn real level condition.
Summary of the invention
The purpose of this utility model is to overcome problems of the prior art, and a kind of magnetostriction liquidometer is provided, and stretches in the jar, measures the liquid level of tank interior.
The technical solution adopted in the utility model is:
A kind of magnetostriction liquidometer, comprise float, feeler lever and transmitter gauge outfit, the transmitter gauge outfit is fixed on the feeler lever upper end, the magnetostriction line is housed in the feeler lever, the magnetostriction line links to each other with piezoelectric sensor in the transmitter gauge outfit, magnetostriction liquidometer also comprises the float well, outer chamber, bar and magnet, the float well is made up of the bottom of sealing and sidewall with holes, float is positioned at float well inside, the float top links to each other with the bar bottom, and bar stretches in the outer chamber, and magnet is fixed on the masthead end, feeler lever is placed on the outer chamber outside, and the magnetostriction line is in the magnetic field induction scope of magnet.
Described magnetostriction liquidometer also comprises a visual detector that is fixed on the outer chamber, and the assembly with the magnet induction is housed in the visual detector.
Described float is no center pit structure.
The diameter of described outer chamber is less than the diameter of float well.
The beneficial effect that the utility model had:
(1) the utility model is directly measured a jar interior liquid level, can not be subjected to the influence of ambient temperature and pressure, float is in the float well all the time, can stop impurity and bubble in the liquid to enter, the liquid flow that makes float well inside can be disorderly, metastable measurement environment is provided, and the operating temperature that is particularly useful for flash tank or ambient temperature and jar inner fluid differs at the process jar more than 50 ℃.
(2) float of the utility model use does not have center pit, and under the equal operating mode, its diameter can be littler with respect to the float of band center pit, and is firmer, and with respect to the float of being with center pit, weld seam is less, does not have the center pit latch up phenomenon, and failure rate is relatively low.
