Abstract
The utility model relates to a kind of anti-fluctuation magnetic fluid level gauge, it is characterized in that: be placed in the anti-wave tube in water tank, in anti-wave tube, be provided with guide rod, on guide rod, be provided with the magnetic float that can move along guide rod, the lifting of liquid level in the location following water tank of magnetic float on guide rod and changing, guide rod is connected at the guide rod detection module for detection of change in resistance under the magneticaction of magnetic float outside water tank.Because the liquid level Up-and-down in water tank is indefinite, there is fluctuation, the utility model is with anti-wave tube, thereby improved the control display precision of high water tank, provides guarantee to the normal operation of hot-water heating system.
Description
Technical field
The utility model relates to a kind of anti-fluctuation magnetic fluid level gauge, and for the water tank of hot-water heating system, magnetic fluid level gauge is installed from water tank top, and away from water tank intake-outlet, belongs to the liquid level control field of water tank.
Background technology
The magnetic fluid level gauge in the past using in the water tank of hot-water heating system, mainly contains terminal box, process web member, guide rod, float (magnetic), several most of compositions of back-up ring.
Magnetic fluid level gauge is the upgraded product of glass plate, glass-tube liquid level meter.It has made up glass plate (pipe) liquid level gauge instruction poor definition, the easy defect such as break, and show on the spot need not power supply, and display section and medium are isolated completely, can not be affected because medium pollution makes liquid level observing.Meanwhile, magnetic fluid level gauge and liquid level control switch and liquid level teletransmission become send matched with devices to use, and can carry out far distance controlled and demonstration to liquid level.
Principle of work: magnetic fluid level gauge is that magnetic reed switch and precision resistance are fixed in airtight non-magnetic guide rod equably, taking magnetic float as sensing element, under the effect of liquid buoyancy, fluctuates along guide rod.In the time of liquid level lifting in water tank, magnetic float in guide rod is lifting thereupon also, permanent magnet in float is by changing the resistance of guide rod detection module, thereby magnetic reed switch changes the resistance value of circuit under the effect of magnetic force, analyzing and processing element testing in circuit is to the variation of this resistance value, and convert the standard signal output of 4～20mA to, realize the simulating signal stepless control of liquid level.The equally distributed gap of magnetic reed switch and precision resistance is less, and precision is higher, and it is more accurate to control.The detection module that it is unique and line design, auto thermal compensation, not only circuit is reliable and stable, and product temperature is also very reliable, and is not subject to the impact of temperature, is convenient to install and use.
In conjunction with structure and the principle of work of magnetic fluid level gauge in the past, can find out that magnetic fluid level gauge puts into operation, need the liquid level in water tank to change mild, can not rise and fall indefinite, there is fluctuation, otherwise can cause magnetic float in guide rod indefinite and fluctuate indefinitely along with the lifting of liquid level, cause coming and go of resistance value, the standard signal output converting to is so also unstable, thereby the demonstration control of liquid level is also unstable.Unsettled liquid level shows to be controlled, and can cause very large blind area to water water inlet, brings very big inconvenience to user.
Summary of the invention
The technical problems to be solved in the utility model is also can high precision show control liquid level when the liquid level heave amplitude fluctuating not timing in water tank.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of anti-fluctuation magnetic fluid level gauge, it is characterized in that: be placed in the anti-wave tube in water tank, in anti-wave tube, be provided with guide rod, on guide rod, be provided with the magnetic float that can move along guide rod, the lifting of liquid level in the location following water tank of magnetic float on guide rod and changing, guide rod is connected at the guide rod detection module for detection of change in resistance under the magneticaction of magnetic float outside water tank.
Preferably, be provided with back-up ring in the bottom of described guide rod.
Because the liquid level Up-and-down in water tank is indefinite, there is fluctuation, the utility model is with anti-wave tube, thereby improved the control display precision of high water tank, provides guarantee to the normal operation of hot-water heating system.
Brief description of the drawings
The application schematic diagram of a kind of anti-fluctuation magnetic fluid level gauge that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The utility model relates to a kind of anti-fluctuation magnetic fluid level gauge, be placed in the anti-wave tube 1 in water tank, in anti-wave tube 1, be provided with guide rod 2, on guide rod 2, be provided with the magnetic float 3 that can move along guide rod 2, be provided with the back-up ring 4 that prevents that magnetic float 3 from deviating from the bottom of guide rod 2, the lifting of liquid level in the location following water tank of magnetic float 3 on guide rod 2 and changing, guide rod 2 is connected at the guide rod detection module for detection of change in resistance under the magneticaction at magnetic float 3 outside water tank.
The course of work of the present utility model is: anti-wave tube 1 of the present utility model starts for 5 from process web member, be installed on the outside of guide rod 2 and magnetic float 3, and drop into water tank together with guide rod 2 and magnetic float 3 from tank top, thereby having ensured that guide rod 2 and magnetic float 3 drop into moves required liquid level and change gently in water tank, impact indefinite and fluctuation is not is not risen and fallen.In water tank, magnetic float on guide rod 23 can change along with the liquid level lifting in water tank, under the effect of magnetic force, is changed by guide rod detection module detected resistance, thereby converts the standard signal output of 4～20mA to, to improve the control display precision of liquid level.
