Detailed Description
Unless defined otherwise, all technical terms used in the examples of the present invention have the same meaning as commonly understood by one of ordinary skill in the art. In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention provides an automatic flap metering port, which is used for metering the storage capacity in an oil storage tank, and as shown in the attached drawings 1, 2 and 3, the automatic flap metering port comprises: barrel 1, two turn-ups 3 and two pivot 2.
The bottom of barrel 1 is connected with the oil storage tank, and the inner chamber of barrel 1 and the inner chamber intercommunication of oil storage tank. Two pivot 2 rotationally set up in barrel 1, and the lateral wall of barrel 1 is worn out at the both ends of pivot 2, and the end connection that barrel 1 was worn out to pivot 2 has weight 4, and the focus of weight 4 is not on the axis of pivot 2. The two turning plates 3 are respectively fixed on the two rotating shafts 2. The sum of the areas of the two turning plates 3 is equal to the sectional area of the inner cavity of the cylinder 1, and the two turning plates 3 are driven by the heavy hammer 4 to be positioned in the same plane and contact and seal the inner cavity of the cylinder 1.
The working principle of the automatic flap metering orifice provided by the embodiment of the invention is explained as follows:
during the use, the bottom and the oil storage tank of barrel 1 are connected, and the inner chamber of barrel 1 communicates with the inner chamber of oil storage tank, can carry out the measurement of liquid level height with the measuring scale from the barrel 1 under to the oil storage tank. The rotating shaft 2 is rotatably arranged in the cylinder body 1, and the turning plate 3 is fixed on the rotating shaft 2, so that the turning plate 3 can rotate in the cylinder body 1. When no external force exists, the two turning plates 3 are driven by the heavy hammer 4 to be positioned in the same plane and contact and seal the inner cavity of the barrel body 1, so that the inner cavity of the oil storage tank is isolated from the outside, and oil gas is prevented from leaking. When the metering is needed, the turning plates 3 are turned over under the action of external force when the metering ruler is put into the metering ruler, and a gap which can enable the metering ruler to be put into the metering ruler is formed between the two turning plates 3. When a gap is formed between the two turning plates 3, the contact ends of the two turning plates 3 can both move downwards or both move upwards, and a gap can be formed between the two turning plates 3. The state of flap 3 when turned over to form a gap can be seen in fig. 4. And after the metering is finished, when the external force disappears, the heavy hammer 4 drives the turning plate 3 to return to the plugging position under the action of gravity, and the inner cavity of the cylinder body 1 is plugged.
According to the automatic flap metering port provided by the embodiment of the invention, the heavy hammer 4 drives the flap 3 to automatically reset, so that an oil storage tank can be plugged when metering is not performed, a metering ruler can be conveniently and rapidly put into the metering ruler during metering, and the flap can be automatically reset to plug after metering is finished without manual intervention, so that leakage of oil gas is avoided, the structure is simple, and the operability is strong.
In order to enable the turning plate 3 to turn over the plate 3 in the barrel 1, the barrel 1 is of a cuboid structure, correspondingly, the turning plate 3 is a rectangular plate, and the area of the turning plate 3 is equal to half of the sectional area of the inner cavity of the barrel 1. So set up, not only be convenient for make, and turn over the angle that board 3 can overturn great.
The positions of the two turning plates 3 in the same plane driven by the heavy hammer 4 are the balance positions of the turning plate 3, the rotating shaft 2 and the heavy hammer 4, namely the whole gravity center of the three is at the lowest point at the moment.
As an example, the position of the center line of the turning plate 3 is fixed on the rotating shaft 2, and the center of gravity of the weight 4 and the plane of the axis of the rotating shaft 2 are perpendicular to the turning plate 3. At this moment, when the gravity center of the weight 4 is located at the lowest point, the whole gravity center of the weight 4, the weight 4 and the turning plate 3 are also located at the lowest point, and the two turning plates are in contact with each other and seal the inner cavity of the barrel 1 when the weight 4 is located at the lowest point.
Or, there is certain distance between the centre line position of turning over board 3 and pivot 2, and the board 3 area that turns over of pivot 2 both sides is different promptly, and the plane that weight 4 and pivot 2 are located and turn over board 3 and be the acute angle, just can make when three's whole focus is located the minimum, turns over board 3 and keeps the horizontality, and two turn over board 3 contact and shutoff barrel 1's inner chamber in the coplanar. The relation between the distance between the central line of the turning plate 3 and the rotating shaft 2 and the angle between the plane of the weight 4 and the rotating shaft 2 and the turning plate 3 can be obtained by calculation or experiment by those skilled in the art.
As shown in FIG. 1, the weight 4 can be connected to the end of the rotating shaft 2 through a rod 6, and the rod 6 is not parallel to the rotating shaft 2, so that the center of gravity of the weight 4 is not on the axis of the rotating shaft 2.
Furthermore, the rod 6 is perpendicular to the rotating shaft 2, so that the weight 4 is close to the outer wall of the barrel 1, and the occupied space is small.
In the embodiment of the invention, as shown in the attached figure 1, the top end of the cylinder body 1 is surrounded with an inverted frustum-shaped top eave 5. So set up, can be convenient for the staff carry out the operation such as measuring chi plays down.
In order to prolong the service life, the barrel body 1 is formed by welding aluminum plates, the corrosion resistance of the aluminum plates is good, the aluminum plates can be suitable for various working scenes, the barrel body 1 is prevented from being corroded and damaged, and the service life is long.
Furthermore, turn over board 3 and pivot 2 and can be aluminium matter material, avoid pivot 2 to lead to because of the rotation inconvenience of corrosion to lead to with turn over board 3 and lead to sealed not tight scheduling problem because of the corrosion, improve the stability of using.
The above description is only an illustrative embodiment of the present invention, and should not be taken as limiting the scope of the invention, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention should be included in the scope of the present invention.
