Description

Technical field:

[0001] The utility model relates to the technical field of diesel filling equipment, and more specifically to an oil leakage prevention device for a diesel tank outlet. Background technology:

[0002] Some existing factories, such as the chemical industry, need to use diesel as a raw material, and diesel is generally stored in a diesel tank, which is buried in the ground. When in use, the diesel needs to be transported out through a pump body for supply. Therefore, a pump body is generally installed on the tank body, and the discharge port of the pump body is connected to an oil outlet pipe. The upper part of the oil outlet pipe extends out of the ground, and a connector is connected to the top of the oil outlet pipe. The inlet of the tank to be filled can be connected to one end of the connecting pipe, and the other end of the connecting pipe is connected to the connecting head. The pump body is opened, so that the oil in the diesel tank can enter the connecting pipe along the oil outlet pipe, and then enter the tank body from the connecting pipe;

[0003] However, after the filling is completed, when the connecting pipe is removed from the connecting head, the diesel in the pipe will flow out, causing waste and polluting the surrounding ground. Utility model content:

[0004] The utility model aims to overcome the deficiencies of the prior art and provides a device for preventing oil leakage at the outlet of a diesel tank, which can stop filling a connecting pipe connected to a connecting pipe head and, after being pulled out from the connecting pipe head, allow the diesel in the connecting pipe and the diesel at the end of the connecting pipe head to flow into an oil receiving barrel without spilling onto the ground and causing waste.

[0018] For example, see Figures 1 to 3 As shown, a diesel tank outlet anti-leakage device includes an oil outlet main pipe 10, the upper part of the oil outlet main pipe 10 extends out of the ground and is connected to an intermediate connecting pipe 20, and the top of the intermediate connecting pipe 20 is connected to an oil outlet connector 30; the bottom end of the oil outlet main pipe 10 extends into the oil outlet of a pump body installed on a diesel storage tank below the ground, and the oil inlet connecting pipe connected to the oil inlet of the pump body extends into the diesel storage tank. This type of structure is a conventional structure and will not be described in detail here.

[0019] A connecting rod 40 is fixed on the side wall of the intermediate connecting pipe 20, and an oil receiving barrel 41 is fixed at the end of the connecting rod 40. The oil receiving barrel 41 is located directly below the oil outlet connector 30. The bottom end of the oil receiving barrel 41 is connected to a lower connecting pipe 42, and a valve 43 is connected to the lower connecting pipe 42. The top surface of the outward-facing side wall plate of the oil receiving barrel 41 is formed with an arc groove extending downward.

A third flange 31 is welded and fixed to the bottom end of the oil outlet connector 30, and the third flange 31 is communicated with the middle flow through hole of the oil outlet connector 30.

[0022] The first flange 21 and the bottom flange 11 are fixedly connected by bolts, and a first sealing ring 1 is clamped between the first flange 21 and the bottom flange 11. The second flange 22 and the third flange 31 are fixedly connected by bolts, and a second sealing ring 2 is clamped between the second flange 22 and the third flange 31.

[0023] The oil outlet connector 30 is a bent pipe connector, the bottom end of which is welded and fixed to the top surface of the third flange 31. The upper end of the oil outlet connector 30 is threaded with a pipe connector 32, and a raw tape is clamped between the internal thread of the pipe connector 32 and the external thread of the upper end of the oil outlet connector 30 to achieve sealing.

[0024] Furthermore, the side wall of the intermediate connecting pipe 20 is connected to a vent pipe 50, and the bottom end of the vent pipe 50 is welded and fixed to the outer side wall of the intermediate connecting pipe 20 and communicates with the side through hole formed on the side wall plate of the intermediate connecting pipe 20;

[0025] The vent pipe 50 is a curved pipe that is bent in an upward arc shape, and a second valve is screwed on the top end thereof (a raw tape is clamped between the inner thread at the bottom end of the second valve and the outer thread at the top end of the vent pipe 50 to achieve sealing), the top end of the second valve is screwed on one end of a transverse pipe 51 (a raw tape is clamped between the inner thread at the top of the second valve and the outer thread at one end of the transverse pipe 51 to achieve sealing), the other end of the transverse pipe 51 is screwed on one end of a curved pipe connector 52 (a raw tape is clamped between the outer thread at the end of the transverse pipe 51 and the inner thread at one end of the curved pipe connector 52 to achieve sealing), the other end of the curved pipe connector 52 is bent downward and screwed on a vertical pipe 53 (a raw tape is clamped between the top outer thread of the vertical pipe 53 and the inner thread at the bottom end of the pipe connector 52 to achieve sealing), the bottom end of the vertical pipe 53.

[0026] Furthermore, the height of the transverse pipe 51 is higher than the upper end of the oil outlet connector 30 and the pipe connector 32 .

[0027] Furthermore, a raised ring 111 extending upward is formed on the top surface around the central through hole of the bottom flange 11, and a raised ring 111 extending upward is also formed on the top surface around the central through hole of the second flange 22. The first sealing ring 1 and the second sealing ring 2 are clamped on the outer side walls of the corresponding raised rings 111.

[0028] Furthermore, a metal conductive strip 3 is connected between the bottom flange 11 and the first flange 21, one end of the metal conductive strip 3 is clamped between the top surface of the first flange 21 and the bottom surface of the corresponding rotating portion of the bolt, and the other end is clamped between the bottom surface of the bottom flange 11 and the top surface of the corresponding nut;

[0030] When this embodiment is in use, the end of the connecting pipe of the tank to be filled is connected to the connecting pipe head 32, and the pump body is opened to allow the diesel in the diesel tank to be drawn out and enter the tank through the connecting pipe. At this time, the second valve is in a closed state.

[0031] When the filling is completed, the pump body stops running, and the second valve opens, so that the intermediate connecting pipe 20 is connected to the outside. Due to the effect of atmospheric pressure, external air enters the intermediate connecting pipe 20, causing the diesel in the intermediate connecting pipe 20 and the oil outlet main pipe 10 to drop and flow back into the diesel tank.

[0032] Then, the end of the connecting pipe is pulled out from the connecting head 32. At this time, the diesel in the connecting pipe and the diesel at the connecting head 32 will flow into the oil receiving barrel 41 for storage. After the connecting pipe 32 is pulled out, it can lean against the bottom surface of the arc-shaped groove on the top surface of the outward side wall panel of the oil receiving barrel 41, so that it is not easy to swing left and right, so that it will not be wasted.

[0033] After all the oil is discharged, the connecting pipe is removed, and the valve 43 is opened, so that the oil in the oil receiving barrel 41 can enter the barrel body 100 below from the bottom of the valve 43, be collected, and can be reused.

[0034] The installation of the metal conductive belt 3 allows all components on the oil outlet main pipe 10 to be grounded, thus preventing accidents caused by sparks caused by static electricity.

[0035] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
