Oil discharge device of railway tank car

Technical Field

An oil discharge device of a railway tank car belongs to the technical field of railway freight cars.

Background

At present, the main problems in the loading and unloading processes of domestic light oil tank trucks are as follows:

1. when filling the railway tank car with light oil from the upper part, the crane pipe is inconvenient to operate due to the large size of the crane pipe, and the crane pipe cannot be inserted into the bottom of the tank car, so that the oil is lost and static electricity is caused.

2. When the oil discharge operation is carried out at the upper part in a high-temperature environment in summer, air resistance is easily generated at the high point of the oil filling riser, the oil discharge efficiency is reduced, the operation time is prolonged, and the evaporation loss of oil products is increased. In severe cases, the oil circuit is cut off due to air resistance, and the unloading operation is interrupted.

3. With the continuous promotion of high speed and heavy load in the railway industry, the situation that the large-load railway tank car is inconvenient to load and unload is increasingly obvious in the face of the fact that the existing loading and unloading facilities are fixed and cannot be transformed in a short period. The existing loading and unloading mode is broken through, and a novel loading and unloading device is possibly developed.

4. Aiming at loading, unloading and transporting oil materials in a mining area, the instantaneity of oil unloading and the high cost of equipping professional loading and unloading equipment are faced, and the research and development of a novel loading and unloading device becomes a necessity.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the oil discharge device of the railway tank car is provided with two-stage oil discharge valves at the middle part and the end part, so that leakage double protection is realized while two-stage opening and closing protection is realized, and the running safety coefficient of a vehicle is improved;

2. the two-stage opening and closing protection is realized, the loss and static electricity of oil products are not caused, and the operation is convenient; air resistance can not be generated, the oil unloading efficiency is improved, the operation time is reduced, and the evaporation loss of oil products is reduced to the maximum extent.

3. The oil discharge pipe fixing device adopts a combination mode of cork and a metal mounting seat, and has certain adjustability in the vertical direction and the transverse direction, wherein the vertical direction is adjusted through an adjusting pad, and the transverse direction is adjusted through a long round hole preset on the valve mounting seat; the cork is used, so that the stress condition of the oil discharge pipe in the empty and heavy vehicle states can be improved while the assembly difficulty is reduced, and the condition that a welding seam fails or sealing fails and further medium leakage occurs is avoided.

4. The internal thread of the end protective cover is matched with the thread of the oil drain port, so that the thread of the oil drain port is effectively protected from being damaged while foreign matters are prevented from entering the oil drain port, and connection failure is avoided.

5. The oil discharge port of the oil discharge device adopts two interface forms of a flange and a thread, so that the oil discharge port is easy to disassemble and convenient to maintain, and the requirement on user interface facilities is reduced.

6. The sealing ring placing ring groove is formed in the flange face, so that the sealing effect is improved while the sealing ring is prevented from moving.

7. The T-shaped three-way pipe structure converts related line welding seams in the prior art into annular welding seams, improves the stress condition, improves the welding quality and reduces the medium leakage risk.
