The applicant applied for "a oil flow monitor" utility model patent again in 2010, 7/5/2011, and granted to the utility model patent in 2011, 2/16/ZL, the patent number is ZL 201020246964.1.

With the expansion of the product application field, the problems of disordered reaction and inaccurate monitoring appear in remote areas and individual key fields. The product of the method has to be improved, the analysis is performed, and the tracking of the electronic integrated block generates error signals, which are caused by the interference of the environment of individual places. The electronic integrated block is modified, is suitable for special environments and cannot increase the cost.

In view of the above-described structure and adjustment of the electronic components, it is necessary to apply new patents for modified oil flow monitor products.

Disclosure of Invention

An object of the utility model is to provide a mechanical type oil flow monitor, the utility model discloses replace electronic component tracking scanning form with mechanical transmission form, owing to be mechanical transmission, eliminated external different signal interference to the environment that has eliminated individual place is done together the phenomenon, makes the oil flow monitor reaction sensitive, the dependable performance, and has reduced the manufacturing cost of product.

The utility model aims at realizing through the following technical scheme:

a mechanical oil flow monitor is composed of casing, rotary axle, press cover, floating plate and dial plate, the casing is divided into two cavities by partition plate, the rotary axle passes through the partition plate and is connected to upper and lower cavities, the upper cavity is equipped with limit switch, concave wheel and pointer, the lower cavity is equipped with floating plate and spring, and the transparent cover plate is fastened to outside.

The shell of the mechanical oil flow monitor is divided into an upper cavity and a lower cavity by a partition plate, a rotating shaft penetrates through the upper cavity and the lower cavity to be connected in a linkage manner, and the upper cavity is provided with a touch limit switch, a concave wheel connected with the upper end of the rotating shaft, a pointer and a dial plate; the lower cavity is provided with a floating plate linked with the rotating shaft, and the shape of the floating plate is different due to the stress area and the difference of the shape of the buoy according to monitoring.

The mechanical oil flow monitor is characterized in that the inner cavity of the shell is divided into two inner cavity glands by a partition plate, and one side of each inner cavity gland is provided with a pressing ring.

In the mechanical oil flow monitor, the floating plate is arranged at the oil inlet.

The cover plate of the mechanical oil flow monitor is provided with red and green indicator lamps.

The utility model has the advantages and effects that:

the utility model discloses in prescribing monitoring fan shape, its floating plate promotes the pivot of linkage when the medium flows, use the pivot to rotate for the heart of a circle and the concave wheel that is connected with the pivot rotates with the pointer simultaneously, the pointer is corresponding with actual flow in dial plate position, and when cutting off or be less than monitoring fan shape floating plate and return 0 degree position smoothly under spring pressure; the rotation of the concave wheel pushes the limit switch, and different position signals are sent out through the limit switch contacts due to different positions of the concave wheel.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a top view of fig. 1.

In the figure: the device comprises a shell 1, a pressing ring 2, a partition plate 3, a spring 4, a floating plate 5, a pointer 6, a rotating shaft 7, a limit switch 8 and a concave wheel 9.

Detailed Description

The present invention will be described in detail with reference to the embodiments shown in the drawings.

The utility model discloses oil flow monitor has general installation form and uses.

The utility model discloses the dial plate shows that the medium normally flows dual signal with the improper flow. The output is a passive signal, so that the computer and the host can be conveniently contacted; the indicator displays double signals of normal flowing and abnormal flowing of the medium, the cover plate is provided with a light emitting diode, the normal flowing green tube is bright, and the abnormal flowing red tube is bright.

As shown in fig. 1 and 2: the structure of the device comprises a bk shell 1, a pressing ring 2, a partition plate 3, a spring 4, a floating plate 5, a pointer 6, a rotating shaft 7, a limit switch 8 and a concave wheel 9. When the medium flowed in by the oil inlet, the medium flow be less than keep watch on when the fan, the medium will be flowed through and can not overcome the spring resistance on the floating plate by floating plate clearance all around, and the floating plate rotates the biggest angle and does not exceed 15 degrees.

When the medium flows in from the oil inlet, the flow of its medium is when keeping watch on in the fan wei, and the medium will overcome spring 4 resistance, promotes floating plate 5 and rotates, and pivot 7 rotates with dress pointer 6 in the pivot and realizes needle demonstration.

Simultaneously epaxial concave wheel 9 rotates thereupon, and when the floating plate rotatory 20 degrees fan shape when, concave wheel rotation touches limit switch 8 and sends the positive mobile signal of medium and green light is bright.

When the medium does not flow, the floating plate 5 returns to the position of 0 degree by the thrust of the spring 4, at the moment, the concave wheel also returns to the lowest point position, and the limit switch 8 is triggered to send out a signal that the medium does not flow normally, and the red light is on.
