Open type magnetic float for magnetic float liquid level sensor

Technical Field

The utility model relates to a be used for magnetism float level sensor open type magnetism float.

Background

In the prior art, a magnetic float liquid level sensor is composed of a mounting flange, a measuring rod, a magnetic float and a magnetic position detection mechanism (magnetic float position detection mechanism). The magnetic float is made up by fixing permanent magnetic ring in the hollow ball made of stainless steel or plastic, and is covered on the measuring bar of liquid level sensor by means of central guide tube of magnetic float, and in order to regulate specific weight of magnetic float, the stainless steel counterweight is mounted in the hollow ball, and when it is used, the sensor is inserted into the container, and is sealed and fixed in the container by means of sensor flange and vertical to horizontal plane.

At present, the liquid level sensor is widely applied to normal pressure containers and pressure containers for liquid level or interface measurement, but many process treatment containers of petrochemical and pharmaceutical enterprises run on line, the flange hole on the container is small, the diameter of the flange is smaller than that of a magnetic float, and the magnetic float liquid level sensor cannot be installed and used without being inserted into the container. In addition, the liquid in some containers has high viscosity, the magnetic float is stuck by the liquid level with high viscosity, and the magnetic float can not float up and down along the measuring rod of the liquid level sensor along with the liquid level change of the containers. The traditional method for solving the problem of sticking the ball (magnetic float) is to increase the size of the floating ball and overcome the problem of sticking the ball by using the large buoyancy of the large float, but the through diameter of the flange mounting hole on some containers is small, and the large-diameter magnetic float cannot enter the container.

Disclosure of Invention

An object of the utility model is to provide a magnetism float level sensor open type magnetism float, it is little effectively to solve mounting flange hole latus rectum on the container, can not install the technical problem of big buoyancy magnetism float.

The utility model provides an open-type magnetism float for magnetism float level sensor, comprises magnetism float measuring staff pipe, 4 sections hollow float wings and permanent magnetic ring and the counter weight nut of seal installation in the magnetic ring box which characterized in that: the 4-segment hollow float wings are in a round head thin rod shape when being contracted together, are on a horizontal plane perpendicular to the guide pipe when being opened, are connected with the guide pipe through a rotating shaft, the rotating shaft is provided with a positioning spring, the 4-segment hollow float wings are folded and condensed into a thin round head rod shape under the action of external force, after the external force is eliminated, the 4-segment hollow wings are automatically opened along the rotating shaft under the action of the spring and are limited by the root magnetic ring box, and the 4-segment hollow wings are vertically on a horizontal plane of the measuring rod guide pipe after being opened. The permanent magnetic ring is sleeved on the measuring rod guide pipe and is fixed in the magnetic ring box in a sealing mode.

The utility model discloses open type magnetic float can select 4 hollow float wings to fold rod-shaped diameter and length together according to container flange latus rectum and magnetic float buoyancy size needs. When the open type magnetic float is installed and used, the diameter of a round head rod shape when 4 pieces of hollow float wings of the open type magnetic float are folded is determined according to the size of the through diameter of a container flange, the length of the round head rod shape when the 4 pieces of hollow float wings are folded is selected according to the buoyancy of the magnetic float, the head of the well-made open type magnetic float is upwards sleeved from the bottom end of a measuring rod of a sensor, a lower retaining ring of the measuring rod is fixed, then the upper float wings of the measuring rod are folded together into a rod shape, the measuring rod of a liquid level sensor and the magnetic float are inserted from the flange opening of the container, the open type magnetic float is immediately opened into four pieces in one horizontal plane after entering the container, the sensor is fixed on the container through a flange at the top end of the sensor, and the open type magnetic float.

The beneficial effects of the utility model

1. The diameter size of the closed rod-shaped of 4 pieces of hollow float wings of the open type magnetic float can be selected according to the diameter size of the through hole of the flange mounting hole on the container, and the technical problems that the through hole of the mounting flange on the container is small and a magnetic float liquid level sensor cannot be mounted and used are solved.

2. The closing rod-shaped length of the opened float wing can be properly increased according to the large viscosity of the liquid, so that the aim of increasing the buoyancy of the float is fulfilled, and the technical problem of measuring the viscosity of the liquid sticky ball (float) by using a float type liquid level sensor is solved.

Detailed Description

As shown in fig. 1, 2 and 3, a stainless steel permanent magnetic ring box 5 with a circular hole in the center of a bottom cover and the same size as the outer diameter of a magnetic float guide pipe 1 is sleeved into the magnetic float guide pipe 1 with the opening facing upwards, the bottom of the magnetic ring box 5 is vertically welded and fixed on a measuring rod guide pipe 1, 4 hollow float wing rotating shaft brackets 2 are uniformly distributed and welded and fixed on the outer wall of the magnetic float guide pipe 1, a permanent magnetic ring 6 is sleeved into the magnetic ring box 5 from the upper end opening of the guide pipe 1 and is sealed and fixed, a counterweight nut 8 is sleeved and fixed from the upper end opening of the magnetic float guide pipe 1, the ends with holes of four float wings 5 are inserted into the rotating shaft bracket 2 on the outer wall of the magnetic float guide pipe 1, the ends with holes of the hollow float wings 7 are aligned with the holes of the rotating shaft bracket 2, the rotating shaft rod 3 is penetrated and a positioning spring 4 is installed for fixing, and then the assembly. When the magnetic float liquid level sensor is installed and used on a container, an open type magnetic float head is upwards sleeved from the bottom end of a sensor measuring rod 9, a lower retaining ring 10 at the bottom end of the sensor measuring rod 9 is installed, then four hollow open type magnetic float wings 7 of the open type magnetic float are folded into a rod shape, the measuring rod 9 of the magnetic float liquid level sensor and the open type magnetic float are inserted into the container 14 from a flange opening 12 on the container 14, the four-petal hollow float wings 7 are automatically opened under the action of a positioning spring 4 and limited by a magnetic ring box 5, the four open type hollow float wings 7 are perpendicular to a magnetic float guide pipe 1 and are on a horizontal plane, the liquid level sensor is hermetically installed in the container 14 through a liquid level sensor installation flange, the open type magnetic float vertically floats along the sensor measuring rod along with the liquid level change of the container, and the installation of the magnetic float liquid level sensor on the container is finished.
