Abstract
The utility model relates to a digital display liquid-level gauge with the safe essence which can use digits to display the height of the liquid level, belonging to liquid level measurers in containers. The digital display liquid-level gauge with the safe essence is composed of a magnetic floater device and a digital display detecting device. A magnetic floater conducts a magnetic induction element whose height is corresponding to the magnetic floater through the magnetic induction, height values are displayed on a digital display meter. The height of the liquid level can be read visually and accurately. The digital display test device is provided with a battery power supply, and external power and connecting wire are not needed. The test current is smaller than 1 microampere, the voltage is smaller than 1 millivolt, and the digital display liquid-level gauge with the safe essence is completely isolated with liquid media. The essence is safe. The numerical values of the liquid level can be displayed with the distant transmission. The utility model uses a fully sealed structure and has the advantages of reliable use in various environment, long service life and convenient installation.
Description
For a long time, the level gauging of various liquid level media is all with the naked eye watched the scale on the liquid level gauge in the containers such as large-scale storage tank, spherical tank, particularly is under the high-order situation in liquid level, watches not only difficulty but also not accurate enough.In addition, because container inner mediums such as large-scale storage tank, spherical tank mostly are inflammable explosive article, safety becomes primary problem.Though general liquid level gauge is provided with the safety anti-explosive device to hidden danger due to the electric current of its part of detecting, the voltage, its essence is unsafe.And the liquid level gauge working condition that is used for large-scale storage tank etc. is poor, has influenced the serviceability and the serviceable life of liquid level gauge.
The purpose of this utility model provides a kind of numeral of using and shows liquid level, the digital display liquid level gauge of reliable working performance, essential safe type.
The digital display liquid level gauge is made up of the two large divisions: magnetic float device, digital display proving installation.Stream oriented device tightens together, and by the magnetic induction conducting, makes liquid level gauge in running order.
Fig. 1 is a digital display liquid level gauge structural representation
Fig. 2 is the side view of Fig. 1
Fig. 3 is an A-A cut-open view among Fig. 1
Fig. 4 is magnetic induction chi [a 3] structural representation
Fig. 5 is magnetic induction chi [a 3] cut-open view
Stainless steel seamless pipe [1], seal with flange [2] upper end, seal with the flange [5] that blowoff valve [6] are housed the lower end, in establish magnetic float [7], constitute the magnetic float device.(see figure 1)
One group of magnetic strength element [9] is contained on the chi core [10] by scale, forms and liquid level scale circuit one to one with parallel form, and chi core [10] embeds chi frame [8], constitutes magnetic induction chi [3].(seeing Fig. 4,5)
Magnetic induction chi [3] is connected with digital display meter [4], constitutes the digital display proving installation.(seeing Fig. 1, Fig. 2)
Magnetic induction chi [3] is fastened on the stainless steel seamless pipe [1], and the magnetic float device is connected with the container that liquid medium is housed.According to a kind of liquid contour principle of liquid level in the different vessels that is connected, the position of magnetic float [7] is a liquid level in the container.By magnetic induction, the spring leaf of separation is inhaled together, i.e. conducting the magnetic strength element [9] of corresponding liquid level, thereby the test circuit of conducting logotype digital display meter [4] is presented at level readings on the fluorescent screen.When liquid level was in upper and lower extreme position, the magnetic induction part [9] of the corresponding extreme position of conducting was connected with alarm on this circuit, can report to the police.The alarm power supply is independent, is the 1.2V rechargeable battery, and working current is less than 10 milliamperes.
Advantage of the present utility model is as follows:
1, numeral shows liquid level, direct reading on the fluorescent screen, accurately, fast.
2, proving installation and liquid medium are isolated fully, and less than 1 millivolt, electric current is less than 1 microampere by the logical test circuit voltage of magnetic conductance, essential safety.
3, because this liquid level gauge adopts all-sealed structure, be not subjected to the influence of external condition, stable work in work, reliable.Waterproof, protection against the tide, anticorrosion, long service life has overcome general liquid level gauge and influenced by operating mode, damages the shortcoming that serviceability is stable inadequately easily.
4, when liquid level is in upper and lower extreme position, the sensing element [9] of the corresponding extreme position of conducting is connected with alarm on this circuit, the right warning.
5, digital display meter [4] links to each other with the circuit of magnetic induction chi [3], can be contained in magnetic induction chi [3] lower end according to actual needs, constitutes the one (see figure 2).Also can be contained in the machine room away from container, teletransmission shows.
6, be connected with timer on the test circuit, start back 5～10 minutes as no liquid level change the just shutdown automatically of digital display proving installation, and have the not enough warning function of battery electric power.
