An automatic oil extraction jet fuel water measuring syringe

Abstract

The utility model provides an automatic oil extraction jet fuel water testing syringe, comprising a syringe body, an oil discharge port, an oil extraction port and an extraction mechanism, wherein the extraction mechanism comprises a pull rod, a piston and a spring sleeve that can automatically rebound. When oil needs to be extracted, the pull rod is pressed to send the piston to a specified position, and the oil extraction port is extended into the oil. After the pull rod is released, the oil is automatically extracted into the syringe. The oil discharge port is a one-way channel that can only discharge oil but not extract it. When the detection is completed, the oil can be quickly discharged from the oil discharge port. The utility model reduces the labor intensity of the user and improves work efficiency through the mutual cooperation of the syringe body and the oil extraction port, the oil discharge port and the extraction mechanism.

Description

Technical Field

[0001] The utility model belongs to the technical field of syringes, and in particular relates to an aviation fuel water measuring syringe for automatic oil extraction. Background Art

[0002] According to the requirements of Article 11 of the "Civil Aviation Fuel Quality Control and Operation Procedures" (MHT6020-2012), the sedimentation tank or low point of the storage tank where the fuel is sent out on the same day should be discharged and inspected every day. The frequency of inspection should be increased when it rains frequently or after heavy rain. After flushing the fuel between the storage tank and the quality inspection tank at full flow rate, extract the fuel sample online for visual inspection. If the inspection shows that the fuel is unqualified, discharge should continue until the inspection is qualified.

[0003] At present, the above operations are all completed manually on-site using existing ordinary plastic syringes. Due to material reasons, ordinary plastic syringes will produce a large damping feeling after long-term and high-frequency use, which will make it difficult for operators to control the strength, making operation inconvenient and work efficiency low.

This is for the convenience of describing the structure of the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0020] The utility model provides Figure 1 The jet fuel water testing syringe with automatic oil extraction shown includes a syringe body 1, an oil suction port 2 for installing a water testing paper, an oil discharge port 3 and an extraction component, wherein the oil suction port 2 is located at one end of the syringe body 1, the extraction component is located at the other end of the syringe body 1, and the oil discharge port 3 is located on the side of the syringe body 1 near the oil suction port 2.

[0021] The extraction component includes a piston 7 and a pull rod 10, and a handle 11 located at one end of the pull rod 10. The piston is located inside the syringe body 1 and can slide along the inner surface of the syringe body 1.

[0022] The spring sleeve 9 includes a spring 901 sleeved on the pull rod 10, two symmetrical limiting protrusions 902 and 903 fixed on one end of the pull rod 10 close to the handle 11, and two opposite limiting protrusions 904 and 905 fixed on the other end of the spring sleeve.

[0023] The oil outlet 3 includes an oil inlet space 301, an oil outlet space 302, a tube wall 304, a valve body 303, a first space 305, a second space 306, a first oil through port 307, a second oil through port 308, a spring 310, and a baffle 309. The valve body 303 can slide along the inner wall of the tube body 304. One end of the valve body 303 is connected to the baffle 309 through a spring 310. One end of the spring 310 is fixed on the baffle 309, and the other end is sleeved on the valve body 303. The first space 305 and the second space 306 are formed between the valve body and the tube wall. The first oil through port 307 and the second oil through port 308 are also opened on the side wall of the valve body 303.

[0024] A pull ring 5 and a handle 6 are also fixed to one end of the syringe body 1 away from the oil discharge port 3. A measuring scale 4 is engraved on the outer surface of the syringe body 1.

[0025] When the water content in the aviation kerosene needs to be measured, the water test paper 12 is first installed on the oil suction port 2, and then the pull rod is pushed to push the piston 7 to the scale of the oil amount to be extracted according to the setting, such as Figure 2 As shown, when the pull rod 10 is pushed, the pull rod 10 in the spring sleeve 9 is fixed with limit protrusions 903 and 904, which will move with the pull rod and compress the spring 901. The inner surface of the spring sleeve 9 is also fixed with limit protrusions 904 and 905, which cooperate with each other to squeeze the spring. When the piston reaches the specified scale, the oil suction port 2 with the water test paper installed is extended into the aviation kerosene to be tested.

[0026] It should be noted that a one-way valve is provided inside the oil discharge port 3, and the oil discharge port 3 can only be used to discharge aviation kerosene, and kerosene cannot enter the syringe from the oil discharge port 3. Figure 3 , which is an internal schematic diagram of the oil outlet 3 of the utility model, the oil outlet 3 includes an oil inlet space 301, an oil outlet space 302, a tube wall 304, a valve body 303, a first space 305, a second space 306, a first oil hole 307, a second oil hole 308, a spring 310, and a baffle 309. The valve body 303 can slide along the inner wall of the tube body 304, one end of the valve body 303 is connected to the baffle 309 through a spring 310, one end of the spring 310 is fixed on the baffle 309, and the other end is sleeved on the valve body 303, a first space 305 and a second space 306 are formed between the valve body and the tube wall, and a first oil hole 307 and a second oil hole 308 are also opened on the side wall of the valve body 303. When the kerosene in the syringe needs to be discharged, the oil enters from 301, the oil squeezes the valve body 303, the spring 310 connected to the bottom of the valve body 303 is compressed, the valve body 310 slides toward the liquid flow direction, the oil enters the first space 305 and the second space 306, and then the oil enters 302 through the first oil port 307 and the second oil port 308 on the valve body 303 and is discharged. When the oil enters from 302, the valve body will block the passage of the oil.

[0027] By providing an oil discharge port 3 with a one-way valve, the oil discharge port 3 can be kept in a closed state when pumping oil. After the oil suction port 2 is inserted into the oil, the hand pressing the pull rod is released, and the compressed spring 901 stretches out, driving the pull rod and the piston to move, and the oil is pumped into the syringe. When the test is completed, the pull rod can be pushed to discharge the oil from the oil discharge port 3. Since the water test paper is installed on the oil extraction port 2, it will hinder the discharge of the oil. By providing a one-way oil discharge port, the oil can be quickly discharged.

[0028] The pull ring 5 and the pull rod 6 arranged on the syringe body 1 can enable the user to hold the syringe better, allowing the user to hold and use it with one hand.

[0029] Although the utility model has been described in detail above by means of general description, specific implementation methods and tests, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model based on the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
