Description

Water-level detector of water level controller

The utility model relates to the water level detector of the water supply system of a kind of skyscraper and industrial and mineral, and particularly a kind of control height of water level is adjustable arbitrarily, the water level detector that output signal keeps voluntarily, and being applicable to needs the automatic water tank water tower of controlling water level etc.

Existing water level controller mainly is made up of up and down two water level detectors, Main Control Tank, water pumps, and water level detector mainly contains two kinds of forms: dry-reed and transistor type.The dry-reed water level detector, be that two tongue tubes up and down are housed in the copper pipe of lower end closed, a band normally-closed contact, a band normally opened contact, the length of copper pipe and the position of tongue tube all should require to determine according to water tank water tower size of being controlled and concrete water level control before production, after the production moulding, can't change voluntarily.Two locating rings up and down are housed on copper pipe, in case move the locating ring position for a certain reason, the attitude that then restores to the original state must just can be reorientated with instrument by the professional, and operation is difficulty quite.Be with a ball float on the copper pipe between the locating ring up and down, magnet ring of ball float internal fixation, magnet ring also is enclosed within on the copper pipe, for tongue tube is worked reliably, the gap of ball float and copper pipe is very little, and the magnet ring in the ball float is ferromagnetic particle and the incrustation scale in the adsorbed water very easily, thereby hindering ball float moves freely on copper pipe, cause water-level detecting out of control, thereby must often safeguard, remove ferromagnetic particle and incrustation scale.In addition, can keep a period of time in order to make signal, up to water level bigger variation take place, avoid water pump to start continually, must be kept by the circuit in the Main Control Tank, as the auxiliary contact of relay etc., reliability is low like this, failure rate is high.The transistor type water level detector, high to the material and the processing technology requirement of probe, cost is expensive, the probe metal electrode is under water for a long time, and adhering to of corrosion of metals and incrustation scale particulate will influence detectable signal, needs often to safeguard, and the probe installation is complicated, the back is installed adjusts highly difficult.Transistor (comprising integrated circuit) anti-interference is poor, is subject to power supply and other pulse signal and disturbs, and causes misoperation.In addition, above-mentioned two kinds of form water level detectors, each probe all needs three holding wires to be connected with Main Control Tank, the lead consumption is big during installation, and electric contact is many, and needs with several auxiliary contact (or transistor circuit) to be realized that signal keeps, therefore, the reliability of The whole control circuit reduces.

The purpose of this utility model is that a kind of reliable operation Maintenance free will be provided, and the control height of water level is adjustable arbitrarily, and installation is adjusted simple and convenient, is applicable to the water level detector of all types of water tank water towers.

The utility model is achieved in that water level detector divides on the roof water tank water level detector TC2 under the water level detector TC1 and bottom tank, they are by last lower armature, pull bar, magnet, tongue tube, lead, locating ring up and down, compositions such as ball float, lower armature is passed on pull bar top, magnet is fixed on the pull bar top between the lower armature, be fixed with locating ring up and down in the pull bar bottom, on the pull bar about ball float is enclosed between the locating ring, different is, the tongue tube of last water level detector TC1 is fixed under the lower armature, and the tongue tube of following water level detector TC2 is fixed on the upper armature.In last water level detector TC1, when magnet held lower armature, magnetic field made the reed switch contact closure, and TC1 output water shortage signal is to Main Control Tank, and Main Control Tank starts water pump and draws water.When water level rises to locating ring; ball float withstands fixed firmly ring; when reaching peak level along with water level continuation rising; buoyancy overcomes gravity and magnet magnetic force; make pull bar be moved upward to magnet and hold upper armature, reed switch contact disjunction at this moment, the sufficient signal of the TC1 output water yield is to Main Control Tank; the Main Control Tank control of pump is shut down, and water level no longer rises.Along with user's water, water level begins to reduce, and before the locating ring, magnet holds upper armature under water level is reduced to, and keeps the reed switch contact disjunction, and therefore, the Main Control Tank control of pump keeps stopped status.Reduce to down surely when firmly encircling when water level, gravity makes pull bar be moved downward to magnet and holds lower armature greater than magnet magnetic force, and at this moment water pump begins again to draw water.In like manner, in following water level detector TC2, when magnet holds lower armature, be contained in the reed switch contact disjunction on the upper armature, TC2 output water shortage signal is to Main Control Tank, and the Main Control Tank control of pump is shut down, and by water inlet pipe and float valve tank is added water; When magnet holds upper armature, the reed switch contact closure, the sufficient signal of the TC2 output water yield is to Main Control Tank, and Main Control Tank controls automatically according to the TC1 signal whether turn on pump draws water.

The utility model can realize that signal keeps voluntarily, do not need the auxiliary circuit in the Main Control Tank to keep, water level detector is connected with Main Control Tank only needs two holding wires, and reliability improves, and circuit need not to consider the anti-oxidation etching problem of circuit water-proof problem and exposed electrode on the water surface.Ball float and pull bar gap allow very big, are very loosening cooperations, and the incrustation scale influence can be ignored fully, does not lay magnet in the ball float, does not have the problem of ferromagnetic particle in the adsorbed water.

Below provide embodiment and accompanying drawing thereof.

Fig. 1 is the sectional arrangement drawing of last water level detector TC1.

Fig. 2 is the sectional arrangement drawing of following water level detector TC2.

Fig. 3 is the circuit block diagram of water level controller.

As shown in the figure, upper armature (1), lower armature (2) is fixed on the support (3), support (3) is installed on the shell (11), pull bar (5) passes upper armature (1), lower armature (2) and shell (11) bottom, magnet (6) is fixed on the pull bar (5) between upper armature (1) and the lower armature (2), pull bar (5) can move up and down a bit of distance, be fixed with locating ring (8) and following locating ring (9) in pull bar (5) bottom, last locating ring (8) is adjustable with the position of following locating ring (9) on pull bar (5), ball float (10) is enclosed within on the pull bar (5) between locating ring (8) and the following locating ring (9), in Fig. 1, tongue tube (4) is fixed on the lower armature (2), in Fig. 2, tongue tube (4) is fixed on the upper armature (1).Tongue tube (4) two ends are connected with Main Control Tank with lead (7).

The relation of water level detector and whole water level controller is up and down: have only when the tongue tube among TC1 and the TC2 (4) contact is all closed, Main Control Tank just starts water pump and draws water.As long as among TC1 and the TC2 tongue tube (4) disjunction is arranged, then Main Control Tank switches off the pump and stops pumping.TC1 tongue tube (4) closing of contact, expression water volume in water tank deficiency need begin to draw water, tongue tube (4) contact disjunction, expression water volume in water tank abundance should stop pumping; TC2 is then opposite, tongue tube (4) closing of contact, and expression tank water yield abundance, tongue tube (4) contact disjunction, expression tank water shortage needs water inlet to replenish.

The utility model mainly is to keep water level signal according to the interaction between magnet, armature, the tongue tube, and the position between them concerns more than the foregoing description, and this is a kind of, also has other position relation also can keep water level signal voluntarily.
