Description
Technical field
The utility model relates to a kind of for the cup type magnetic float of falling of magnetic float liquid level sensor.
Background technology
In the prior art, the magnetic float liquid level sensor detects mechanism's (magnetic float position detects mechanism) by measuring staff, magnetic float and magnetic potential and forms.The magnetic float is to be fixed in the hollow ball (or bar-shaped) made from stainless steel or plastic cement by permanent magnet ring to make, and is enclosed within on the liquid level sensor measuring staff by magnetic float centre pipe, for levelling magnetic float proportion, the stainless steel mass is housed in hollow ball.During measurement, liquid level sensor is installed on the container perpendicular to liquid level, the magnetic float changes with liquid level in the container along measuring staff to be gone up, 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 the use procedure, good such as the liquid fluidity in the container, the magnetic float changes with liquid level in the container and moves up and down along measuring staff, magnetic potential detects mechanism and immediately detects tank fill level, large such as liquid in container viscosity, liquid level changes in the container, because the magnetic float has been clung by the large liquid of viscosity, the magnetic float can not change and immediately mobile up and down along measuring staff with liquid level, and along with liquid level in the container rises, it is increasing that the magnetic float is immersed in the liquid part, the buoyancy of magnetic float is also increasing, when only having buoyancy when the magnetic float greater than ball and liquid clinging power, the magnetic float just once floats to suddenly on the liquid level, and the sensor magnetic potential detects the magnetic potential signal that mechanism detects like this, it or not the actual signal of liquid level, but a kick signal causes erroneous judgement, brings adverse effect for production and process of scientific research.In the practical application, many productions and scientific research technological process in order to overcome the low liquid retrogradation of environment temperature in the container, adopt the heating way to strengthen the flowability of liquid, and namely container is equipped with and accompanies hot charging to put.The open-top receptacle that has companion's hot charging to put, low such as environment temperature, although the liquid in container flowability improves, but the liquid in container surface is still very thick, large such as the mobile temperature influence of liquid in container, when the environment temperature very end, although companion's hot charging is arranged in the container to be put, one deck hardcoat but still congeal in the liquid in container surface, at this moment the magnetic float of sensor and hardcoat have thoroughly sticked together, and 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 hardcoat, the magnetic float just floats along measuring staff quickly, at this moment magnetic potential detect mechanism detect liquid level signal quickly kick risen manyly, cause the erroneous judgement that liquid level changes in the container, give and produce and process of scientific research causes adverse effect.Tradition solves ball float and the sticking way of thick liquid is to strengthen the 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 the float size, solve sticking problem, although improve to some extent, can not tackle the problem at its root.
The utility model content
It is a kind of for the cup type magnetic float of falling of magnetic float liquid level sensor that goal of the invention of the present utility model is to provide, and can effectively solve the level gauging problem of the large liquid of viscosity.
Realize the technical scheme of the present utility model purpose:
A kind of for the cup type magnetic float of falling of magnetic float liquid level sensor, form by falling cup type housing, measuring staff conduit, permanent magnet ring, baffle ring and counterweight nut, it is characterized in that: magnetic float housing adopts down cup type structure, falling cup type housing bottom surface is opening, there is through hole at the end face center, the measuring staff conduit is positioned at down cup type housing center, cup type housing end face center pit is pierced into down in the upper end, and be sealedly connected and fixed with center pit, lower port with fall cup type shell aperture in one plane, permanent magnet ring is enclosed within on the measuring staff conduit fixing.
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 the counterweight nut is positioned at the below of permanent magnet ring.
The bottom surface of counterweight nut is higher than down 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.
The measuring staff conduit is positioned at down the center of cup type housing inboard, 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.
The beneficial effect that the utlity model has
The utility model float adopts down cup type housing, and falling the bottom of cup type housing is opening, and permanent magnet ring is positioned at down in the cup type housing.When 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 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 solve the large liquid of viscosity is carried out the level gauging problem.
