Description

Novel fuel sampling system

Technical Field

The utility model belongs to the technical field of the sample, concretely relates to novel fuel sampling system.

Background

For the operation of ships, fuel sampling, inspection and analysis are very important works. Whether the fuel sample which is not polluted can be obtained quickly, conveniently and reliably, and meanwhile, a sampling person can clearly supervise the whole sampling process, and a good solution is not provided at present.

Among the conventional ship design, when needs fuel sampling, generally increase one section branch pipe and a stop valve on the pipeline, when needs fuel sampling, need the staff, carry the sample oil drum temporarily from the warehouse within a definite time, to fuel sample valve below, open the sample valve, let the fuel flow in the sample oil drum, reach the purpose of fuel sampling.

However, this design has several problems as follows.

1. The sampling device is too crude: when needs sample, still need the staff to carry the oil drum temporarily and take a sample near sampler.

2. The sampling operation is complicated: when the fuel sample, if the exit position of sample valve is improper, can not the lug connection to sample in the oil drum, still need staff temporary connection hose.

3. There is a certain risk: in the sample in-process, if staff's misuse has the risk that the fuel leaked, if the sample valve is sealed not well simultaneously, the condition that the fuel leaked also can appear.

4. The sampling quantity is not easy to control: if the pressure in the pipeline is large, the flow is large after the sampling valve is opened, the flow rate is fast, and the sampling quantity is difficult to control.

5. There is no standardized design: the existing sampling method is that an additional sampling pipeline and a valve are added according to the actual pipeline position and the field condition, the sampling methods of different positions and different ship types are various, and a unified and complete sampling device does not exist.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a novel fuel sampling system, including the sample branch pipe, can dismantle sample jar and bypass pipeline, sample branch pipe one end and fuel pipeline branch pipe, the other end pass through quick-operation joint and can dismantle sample jar access connection, the import and the export that can dismantle the sample jar all are equipped with the needle valve, bypass pipeline one end and sample branch union, the other end with discharge pipeline branch union for the fuel of sampler bypass flows back.

The fuel pipeline branch pipe and the discharge pipeline branch pipe are respectively connected with the oil tank through the fuel pipeline main pipe.

The inlet of the detachable sampling tank is provided with a quick connector and a needle valve, and the outlet of the detachable sampling tank is provided with the needle valve for ventilation. The quick installation and the dismantlement of sample jar can be dismantled have been guaranteed.

Still be equipped with the branch pipe of bleeding on the sample branch pipe, be equipped with the bleeder valve on the branch pipe of bleeding, can realize under the special circumstances, empty the fuel in the sampling device.

The bypass pipeline arranged in the fuel oil sampling system is used for regulating the flow and also has the function of a bypass detachable sampling tank when the sampling device is in failure.

And flow regulating valves are arranged on the sampling branch pipe and the bypass pipeline and used for regulating the flow of the sampling branch pipe and the bypass pipeline.

The sampling branch pipe is also provided with a pressure gauge, so that the state of the sampler can be observed at any time in the sampling process, and whether the sampler works normally or not can be determined.

A stop valve is arranged on the fuel pipeline branch pipe; and a stop valve is arranged on the discharge pipeline branch pipe.

The fuel sampling system is also provided with a grounding device for preventing fire due to static electricity.

When the detachable sampling tank finishes sampling, the needle valve is closed, the detachable sampling tank can be detached, and the sampling is sent out. Meanwhile, the mounting joint is plugged on the quick joint, so that fuel oil leakage is avoided.

The utility model has the advantages as follows:

1. the design of the fuel sampling system is standardized, and any fuel sampling system can use the system.

2. The fuel oil sampling function is more perfect, various complex conditions which can occur on the ship are fully considered, and most of possible risks can be avoided.

3. The dismantlement installation that the sample jar can be quick can be dismantled to the fuel, and completion sample work that can be quick at any time, at the sample in-process, the staff also need not too much attention to the operating condition of sampling system.

4. The standardized design of the detachable sampling tank also ensures the replaceable type of the detachable sampling tank, and a plurality of standardized detachable sampling tanks can be prepared on the ship in a matched manner to finish the repeated sampling and submission.

Detailed Description

Example 1

The utility model provides a novel fuel sampling system, includes sample branch pipe 7, can dismantle sample jar 5 and bypass line 8, 7 one end of sample branch pipe and fuel pipeline branch connection, the other end pass through quick-operation joint 3 with can dismantle 5 access connections of sample jar, can dismantle the import and the export of sample jar 5 and all be equipped with
