Description
Technical field
The present invention relates to a kind of for the cup type magnetic float of falling of magnetic float liquid level sensor and assembly method thereof.
Background technology
In prior art, magnetic float liquid level sensor detects mechanism's (magnetic float position detects mechanism) by measuring staff, magnetic float and magnetic potential and forms.Magnetic float is to be fixed in the hollow ball (or bar-shaped) made from stainless steel or plastic cement and to be made by permanent magnet ring, by magnetic float centre pipe, is enclosed within on liquid level sensor measuring staff, for levelling magnetic float proportion, stainless steel mass is housed in hollow ball.During measurement, liquid level sensor is installed on container perpendicular to liquid level, magnetic float changes and upper moving with liquid level in container along measuring staff, and magnetic potential detects mechanism and immediately detects float position, i.e. liquid level position.
At present, this class sensor is widely used in non-pressure vessel and pressure vessel level gauging, in use procedure, as good in the liquid fluidity in container, magnetic float changes with liquid level in container and moves up and down along measuring staff, magnetic potential detects mechanism and immediately detects tank fill level, as large in liquid in container viscosity, in container, liquid level changes, because magnetic float has been clung by the large liquid of viscosity, magnetic float can not change and immediately move up and down along measuring staff with liquid level, along with liquid level in container rises, it is increasing that magnetic float is immersed in liquid part, the buoyancy of magnetic float is also increasing, only have when the buoyancy of magnetic float is greater than ball and liquid clinging power, magnetic float just floats to suddenly on liquid level once, sensor magnetic potential detects the magnetic potential signal that mechanism detects like this, it not the actual signal of liquid level, a but kick signal, cause erroneous judgement, bring adverse effect to production and process of scientific research.In practical application, much production and scientific research technological process, in order to overcome the low liquid retrogradation of environment temperature in container, adopt heating way to strengthen the mobility of liquid, and container is equipped with heating device.The open-top receptacle that has heating device, as low in environment temperature, although liquid in container mobility improves, but liquid in container surface is still very thick, as large in liquid in container mobility temperature influence, when the environment temperature very end, although there is heating device in container, one deck hardcoat but still congeal in liquid in container surface, at this moment the magnetic float of sensor and hardcoat have thoroughly sticked together, container feed liquor liquid level rises, liquid level surpasses hardcoat, liquid in container has all buried whole magnetic float, ball float also can not float, only have when fluid temperature is hardcoat, magnetic float just floats along measuring staff quickly, at this moment magnetic potential detect mechanism detect liquid level signal quickly kick risen many, cause the erroneous judgement that in container, liquid level changes, cause adverse effect to production and process of scientific research.Tradition solves ball float and the sticky way of thick liquid is to strengthen ball float size, increasing magnetic float buoyancy solves, but magnetic float size is larger and liquid contact surface is long-pending also larger, clinging power is also stronger, with having strengthened float size, solve sticky problem, although improve to some extent, can not tackle the problem at its root.
Summary of the invention
It is a kind of for the cup type magnetic float of falling of magnetic float liquid level sensor and assembly method thereof that the object of the invention is to provide, and can effectively solve the level gauging problem of the large liquid of viscosity.
Based on same inventive concept, the present invention has two independently technical schemes
1, a kind of for the cup type magnetic float of falling of magnetic float liquid level sensor, by falling cup type housing, measuring staff conduit, permanent magnet ring, baffle ring and counterweight nut, form, it is characterized in that: magnetic float housing adopts down cup type structure, housing bottom surface is opening, measuring staff conduit be positioned at down cup type housing inner side and with fall cup type housing and fix, the cup type housing end face that falls has through hole, and this through hole matches and is tightly connected with measuring staff conduit, and the outside of measuring staff conduit bottom is fixed with permanent magnet ring.
Permanent magnet ring is fixed by baffle ring, counterweight nut and measuring staff conduit, and baffle ring is positioned at the top of permanent magnet ring, and counterweight nut is positioned at the below of permanent magnet ring.
The bottom surface of counterweight nut is higher than falling the bottom surface of cup type housing.
The end face of cup type housing is passed down on the top of measuring staff conduit, and the bottom of measuring staff conduit is with to fall the bottom surface of cup type housing concordant.
Measuring staff conduit is positioned at down the center of cup type housing inner side, falls the corresponding through hole that has in center of cup type housing end face.
The xsect of cup type housing of falling is circle or rectangle.
2, a kind of assembly method of falling cup type magnetic float of above-mentioned magnetic float liquid level sensor, it is characterized in that: falling cup type housing end face center processing through hole, this through hole is vertically passed in the upper end of measuring staff conduit, corresponding through hole, by measuring staff conduit and the cup type housing seal welding of falling, by baffle ring, counterweight nut, the bottom of permanent magnet ring and measuring staff conduit is fixed, and the bottom surface that guarantees counterweight nut is higher than falling the bottom surface of cup type housing.
The beneficial effect that the present invention has
The present invention adopts down cup type housing, and falling the bottom of cup type housing is opening, and permanent magnet ring is positioned at down in cup type housing.While measuring liquid level, only have down the opening part of cup type housing bottom to contact with liquid level is vertical with measuring staff conduit lower port, because surface of contact is very little, clinging power is little, even if measure the large liquid of viscosity, float can not be stuck yet, and float all can move up and down along measuring staff along with liquid level changes, thereby efficiently solves the problem of the large liquid of viscosity being carried out to level gauging.
