Description
Technical field
The present invention relates to one kind to be used for magnetic float liquid level sensor opening type magnetic float and its installation and application.
Background technique
In the prior art, (magnetic is floating by mounting flange, measuring staff, magnetic float and magnetic potential detection mechanism for magnetic float liquid level sensor
Sub- position detection mechanism) composition.Magnetic float is fixed in the hollow sphere being made into stainless steel or plastic cement by permanent magnet ring and is made,
It is covered on liquid level sensor measuring staff by magnetic float centre pipe, to adjust magnetic float specific gravity, is provided with stainless steel in hollow sphere
Counterweight is fixed in container in use, inserting the sensors into container by the sealing of sensor flange vertical level.
Current this kind of liquid level sensor is widely used in non-pressure vessel and pressure vessel carries out liquid level or interface level measurement, but is permitted
More on-line operation petrochemical industry, pharmaceutical manufacturer process container, container upper flange hole is small, flange latus rectum be less than magnetic float diameter,
Magnetic float liquid level sensor is inserted not into container, can not be installed and used.In addition, liquid viscosity is big in some containers, magnetic float is glued
It spends big liquid level to cling, magnetic float cannot change with tank fill level to float up and down along liquid level sensor measuring staff.Tradition solves slimeball
(magnetic float) method is to increase floating ball size, the container upper flange for overcoming the problems, such as slimeball using the big big method of float buoyancy, but having
Mounting hole latus rectum is small, major diameter magnetic float An Bujin container.
Summary of the invention
The purpose of the present invention is to provide a kind of magnetic float liquid level sensor opening type magnetic floats, can effectively solve on container
The technical issues of Method for Installation flange aperture latus rectum is small, cannot install big buoyancy magnetic float.
Based on the same inventive concept, there are two independent alternatives.
1, a kind of opening type magnetic float for magnetic float liquid level sensor, by magnetic float measuring staff conduit, 4 valve hollow floats
The wing and the permanent magnet ring being sealingly mounted in magnet ring box and counterweight nut composition, it is characterised in that: the 4 valve hollow float wings, which are shunk, to be closed
Carefully rodlike in round end when together, when opening on one horizontal plane of vertical conduit, every valve float wing is connected by shaft and conduit
It connects, shaft is equipped with retaining spring, and under external force, the 4 valve hollow float wings, which close up, is condensed, external force elimination rodlike as thin round end
Afterwards, the hollow wing of 4 valves is opened along shaft automatically under the action of the spring, is limited by root magnet ring box, and the hollow chord of 4 valves vertically exists after opening
On one horizontal plane of measuring staff conduit.On measuring staff conduit, sealing is fixed in magnet ring box permanent magnetic ring set.
Opening type magnetic float of the present invention can need selected 4 valves hollow according to vessel flange latus rectum and magnetic float buoyancy size
The float wing is close together rodlike diameter and length.
2, opening type magnetic float installation and application
Round end rodlike diameter when determining that the 4 valve hollow float wing of opening type magnetic float closes up according to vessel flange latus rectum size first,
The 4 valve hollow float wings are selected according to magnetic float buoyancy size and close up the rodlike length of round end, by ready-made opening type magnetic float head court
On enter from sensor measuring staff bottom end headgear, fix measuring staff lower baffle ring, then the float wing on measuring staff be close together to be rodlike,
Liquid level sensor measuring staff is inserted into together with magnetic float from container flange port, after opening type magnetic float enters container, is opened at once
It is pintongs in a horizontal plane, sensor vertical horizontal plane is fixed on container by transducer tip flange, opening type magnetic
Float floats up and down along sensor measuring staff with tank fill level variation.
Beneficial effects of the present invention
1, can be according to container upper flange mounting hole latus rectum size, selected 4 hollow float wings of opening type magnetic float close up rodlike straight
Diameter size solves on container the technical issues of mounting flange latus rectum is small, cannot install and use magnetic float liquid level sensor.
2, it can suitably increase the opening type float wing greatly according to liquid viscosity and close up rodlike length, reach and increase float buoyancy mesh
, solve the technical issues of liquid slimeball (float) big with float type liquid level sensor measurement viscosity.
Detailed description of the invention
Fig. 1 present invention is installed to the structural schematic diagram after container.
Fig. 2 present invention is in vessel flange mouth scheme of installation.
Fig. 3 present invention is installed into vessel flange mouth schematic diagram.
Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, bottom cover center there is into the stainless of circular hole identical with 1 outer diameter of magnetic float conduit
The permanent magnet ring box 5 of steel, mouth pack into magnetic float conduit 1 upward, 5 dolly of magnet ring box are directly weldingly fixed on measuring staff conduit 1, by 4
Hollow float wing rotary shaft rack 2 is uniformly distributed the outer wall for being weldingly fixed on magnetic float conduit 1, by permanent magnet ring 6 from conduit 1
The port level of being inserted in is put into magnet ring box 5 and seals fixation, counterweight nut 8 is inserted in fixation from 1 upper port of magnetic float conduit, by four
The float wing 5 injects on 1 outer wall rotary shaft rack 2 of magnetic float conduit with porose end, alignment 7 end holes of the hollow float wing and turns
2 hole of bracing strut puts on shaft bar 3 and installs retaining spring 4 and fix, is i.e. the assembly of completion opening type magnetic float.Magnetic float liquid level
Sensor on container when installing and using, by opening type magnetic float head-up from 9 bottom end headgear of sensor measuring staff into installing biography
9 bottom end of sensor measuring staff head lower baffle ring 10, then the opening type magnetic float four hollow opening type float wings 7 are closed up into it is rodlike,
By magnetic float liquid level sensor measuring staff 9 together with opening type float after 14 upper flange mouth 12 of container reeve container 14, pintongs is hollow
The float wing 7 is acted on automatic opening by retaining spring 4, is limited by magnet ring box 5, four hollow float wings, the 7 perpendicular magnetic float of opening
Conduit 1 and on a horizontal plane, by liquid level sensor mounting flange, liquid level sensor vertical level is sealingly mounted at
In container 14, opening type magnetic float changes with tank fill level, floats up and down along sensor measuring staff, i.e. completion magnetic float liquid level passes
Sensor is installed on container.When needing to extract liquid level sensor out of container, due to 4 float wings, about 7 end of opening
There are a rounded corners, the limit of 7 receptor flange hole of the float wing is closed into rodlike, can extract float type liquid level sensor from container.
