Description

Technical Field

[0001] The utility model relates to the technical field of liquid level measuring floats, in particular to a liquid level measuring float which can prevent the float from being stuck due to stainless steel burrs in a soft cable type probe. Background Art

[0002] In existing technology, a liquid level measuring float, also known as a float level gauge, is an instrument used to detect and control liquid levels. It primarily consists of a float, a rod, and a connecting flange, which is mounted on the top of a container. The float floats on the liquid surface based on the principle that displaced liquids have equal volumes. As the liquid level in the container changes, the float moves up and down accordingly. Due to magnetic attraction, the reed switch in the float level gauge is magnetically attracted, converting the change in liquid level into an electrical signal. The actual liquid position is digitally displayed on a display, enabling remote detection and control of the liquid level.

[0003] In existing technology, flexible cable-type magnetostrictive and reed switch-type level gauges are widely used in tank farms with large ranges ranging from 6 to 20 meters. These in-line floats, used to measure liquid levels or interface levels, typically utilize a thin-walled stainless steel straight tube with a magnet inside, welded to an external stamped part. This design is easy to manufacture and inexpensive. However, in the case of flexible cable-type probes with armored bellows, the outer armored sheath is woven from stainless steel wire, which can cause burrs during processing, transportation, and on-site installation. Furthermore, flexible cable-type probes typically come in lengths ranging from 6 to 20 meters. Consequently, these burrs are often difficult to detect during quality inspections. Furthermore, during installation, burrs caused by localized breakage of the stainless steel wire due to friction can go unnoticed by on-site installers. The 90-degree angle formed at the weld between the straight tube and the float can cause the burr to become stuck, preventing the float from rising. This stuck float can prevent accurate liquid level measurement. Furthermore, repairs are complex and hazardous at high altitudes in crude oil and finished chemical raw material tank farms, making repairs extremely difficult.

[0004] Therefore, the present application proposes a liquid level measuring float that can prevent the float from getting stuck due to stainless steel burrs in a flexible cable probe, in order to solve the above-mentioned problem. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art that the 90-degree right angle formed at the welding point between the straight pipe section and the float ball will be stuck with the burr, resulting in the float ball being unable to rise. After the float ball is stuck, the liquid level cannot be accurately measured. The utility model proposes a liquid level measuring float ball that can prevent the float ball from being stuck due to the stainless steel burr in the soft cable type probe rod.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A level measuring float that prevents sticking due to stainless steel burrs in the flexible cable probe, including a special intermediate tube with double bell mouths;

[0008] The stamping head is sleeved on the outside of the double-bell mouth special intermediate pipe.

[0009] As a preferred solution of the present invention, magnets are fixedly connected to the outer wall of the double-bell mouth special intermediate tube at equal intervals, and the number of magnets is four.

[0010] As a preferred solution of the present invention, the upper and lower parts of the inner wall of the double-bell mouth special intermediate tube are both trumpet-shaped, and the diameter of the trumpet mouth is more than 6 mm larger than the inner wall of the double-bell mouth special intermediate tube.

[0011] As a preferred solution of the present invention, the outer wall of the stamping head is symmetrically provided with a middle welding seam.

[0012] As a preferred solution of the present invention, the top and bottom of the double-bell mouth special intermediate pipe are both provided with two-end splicing, and the stamping head is welded to the double-bell mouth special intermediate pipe through the two-end splicing.

[0013] Beneficial effects:

[0014] The utility model mainly solves the problem of burrs in the soft cable probe causing jamming. Since the burrs are usually short, the double-flared special intermediate tube will not collide with the burrs and get stuck during the installation of the soft cable. At the same time, the burrs can be introduced into the inner tube through a large obtuse angle. At the same time, the gap between the inner tubes is more than 5mm larger than the soft cable, which effectively ensures that the burrs will not get stuck due to 90-degree right-angle welding. The four surrounding magnets provide reliable magnetic field strength, ensuring the one-time success rate of measurement after installation of a large number of soft cable liquid level gauges, improving user experience and saving manufacturer service costs. It is particularly suitable for large-scale tank liquid level or interface position measurement in oil and gas fields or chemical plants with remote locations and complex and changeable on-site conditions.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example

[0019] Reference Figure 1, which can prevent the level measuring float from being stuck by stainless steel burrs in the soft cable probe, including a special double-bell mouth intermediate tube 1;

[0020] The stamping head 3 is sleeved on the outside of the double-bell mouth special intermediate pipe 1.

[0021] As a preferred solution of the present invention, magnets 2 are fixedly connected to the outer wall of the double-bell mouth special intermediate tube 1 at equal intervals, and the number of magnets 2 is four. By setting the magnets 2, the four symmetrical magnets 2 around provide reliable magnetic field strength, ensuring the one-time success rate of measurement after installation of a large number of soft cable liquid level meters, improving user experience, and saving manufacturer service costs.

[0022] As a preferred solution of the present invention, the upper and lower parts of the inner wall of the double-bell-mouth special intermediate tube 1 are both trumpet-shaped, and the diameter of the trumpet is more than 6 mm larger than the inner wall of the double-bell-mouth special intermediate tube 1. Since the burrs are usually short and small, within 3 mm, during the installation of the soft cable, the double-bell-mouth special intermediate tube 1 will not collide with the burrs and get stuck. The large obtuse angle between the slope of the trumpet and the straight pipe section can smoothly guide the burrs in, and the burrs will not get stuck with the soft cable burrs at a 90-degree right angle like traditional floats.

[0023] As a preferred solution of the present invention, the outer wall of the stamping head 3 is symmetrically provided with a middle welding seam 4 .

[0024] As a preferred solution of the present invention, the top and bottom of the double-bell mouth special intermediate tube 1 are both provided with two-end splicing 5, and the stamping head 3 is welded to the double-bell mouth special intermediate tube 1 through the two-end splicing 5.

[0025] The working principle of the present invention is as follows: during the installation of the soft cable, the straight pipe section in the middle of the traditional straight-insert float is replaced with a double-bell-mouthed special intermediate pipe 1. Since the burrs are usually short and small, within 3mm, the double-bell-mouthed special intermediate pipe 1 will not collide with the burrs and get stuck during the installation of the soft cable. The large obtuse angle between the slope of the bell mouth and the straight pipe section can smoothly guide the burrs into the inner pipe. At the same time, the inner diameter of the middle straight pipe is more than 5mm larger than the soft cable probe, and the large gap can pass burrs within 3mm. Therefore, the float effectively ensures that the burrs will not get stuck with the soft cable burrs at a 90-degree right angle like traditional floats. The four symmetrical magnets 2 around it provide reliable magnetic field strength, ensuring the one-time success rate of measurement after installation of a large number of soft cable liquid level gauges, improving user experience, and saving manufacturer service costs. It is particularly suitable for large-scale tank level or interface position measurement in oil and gas fields or chemical plants with remote locations and complex and changeable on-site conditions.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
