Description

The flow meter calibration equipment has a bottom quick-release oil sealing device. Technical Field

[0001] This utility model belongs to the field of oil depot oil quality testing technology, specifically relating to a bottom quick oil unloading sealing device for flow meter testing equipment. Background Technology

[0002] According to the "National Metrological Verification Regulations of the People's Republic of China" [JJG633-2005] and the "Oil Product Metrology Management Measures of China Petroleum Gansu Sales Company (Revised Draft)", the oil depot is required to conduct mandatory verification of 12 flow meters every six months, and the three parties must conduct self-inspection of the flow meters every month.

[0003] During flowmeter calibration, due to the significant height difference between the tanker truck and the standard metal tank, before each mandatory flowmeter test and third-party self-test, the tanker truck driver must first climb to the top of the tanker, pull up the tanker's guardrail, open the manhole cover, and then connect the unloading hose from the tanker's outlet. The unloading hose extends from the manhole into the bottom of the tanker. During the flowmeter calibration process, someone must always be on top of the tanker to supervise. Walking on top of the tanker is extremely inconvenient and poses a risk of personnel falling. If an emergency such as a fire or canopy collapse occurs during the flowmeter calibration process, the oil pipeline cannot be quickly pulled out of the tanker, further increasing the safety risk. Summary of the Invention

[0004] The purpose of this utility model is to provide a quick oil unloading and sealing device at the bottom of a flow meter calibration equipment, thereby overcoming the aforementioned technical problems in the prior art.

[0005] Therefore, the technical solution provided by this utility model is as follows:

[0006] The flow meter calibration equipment includes a quick-release oil sealing device at the bottom, comprising an oil discharge quick connector, an oil discharge hose, and a reducing quick connector connected in sequence, wherein the oil discharge hose is provided with an electrostatic grounding wire.

[0007] The quick-connect coupling and the quick-connect hose are connected at one end via a flange male quick-connect coupling and a quick-connect coupling. The quick-connect coupling and the flange male quick-connect coupling are connected at one end, and the quick-connect coupling is fixed outside the quick-connect hose. The other end of the flange male quick-connect coupling is inserted into the quick-connect hose.

[0008] The other end of the oil hose and the reducing quick connector are connected via a double female quick connector.

[0009] The reducing quick connector includes a housing and a locking buckle. The top of the housing is a reducing head, and a sealing gasket is provided inside the reducing head.

[0010] The flange male end quick connector is connected by screws and an oil-lubricating quick connector.

[0011] The quick-connect oil supply includes a housing and an oil supply switch mechanical handle. The housing contains a shaped ring and a valve core, and the oil supply switch mechanical handle is connected to the valve core.

[0012] One end of the electrostatic grounding conductor is connected to a double-female quick connector, and the other end of the electrostatic grounding conductor is connected to a quick connector.

[0013] Both ends of the oil-filled hose and the static grounding wire are connected by clamps and double female quick connectors and quick connection connectors, respectively.

[0014] The beneficial effects of this utility model are:

[0015] The flowmeter calibration equipment features a bottom-mounted quick-discharge sealing device. This device connects to the bottom oil loading connector of the tanker truck via a quick-connect coupling, and to the standard metal tank oil outlet via a reducing quick-connect coupling. The two ends of the discharge hose are first connected via clamps and double-female quick-connect couplings, and then to a quick-connect coupling. Finally, the quick-connect coupling connects to the discharge quick-connect coupling via a flange male quick-connect coupling, and the double-female quick-connect coupling connects to the reducing quick-connect coupling. This ensures a reliable connection, preventing oil leakage caused by loosening of the joints during handling or storage, and eliminating the possibility of safety and environmental accidents.

[0016] The flowmeter calibration equipment features a bottom-mounted quick-release sealing device. The two ends of the static grounding wire are connected via clamps and double-female quick connectors and quick-connect connectors, effectively preventing static grounding failures that could lead to fires, explosions, or other safety accidents.

[0017] This invention overcomes the safety issues associated with the existing method of returning calibrated oil to the tanker via a pipeline from the standard metal tank's oil outlet to the bottom of the tanker truck through the manhole. By simply installing the quick-unloading sealing device at the bottom of the flowmeter calibration equipment between the standard metal tank's oil outlet and the tanker truck's loading / unloading port, the oil in the standard metal tank can be unloaded into the tanker truck via a pipeline pump, improving operational safety. Simultaneously, the collected oil can be recycled, reducing losses and preventing soil pollution. This also reduces losses during the flowmeter calibration process at oil depots and saves the depot 6720 yuan annually in equipment cleaning and environmental protection costs.

Example 1

[0027] This embodiment provides a quick oil discharge sealing device at the bottom of a flow meter calibration equipment, as shown in Figure 1. It includes an oil discharge quick connector, an oil discharge hose 6 and a reducing quick connector 9 connected in sequence. The oil discharge hose 6 is provided with an electrostatic grounding wire 5.

During the oil dispensing process, unless the locking buckle 12 is manually opened, the reducing quick connector 9 and the double-female quick connector 8 cannot be separated, preventing safety accidents caused by equipment malfunctions. Example 3

[0033] Based on Example 1, this example provides a quick oil unloading sealing device at the bottom of a flow meter calibration equipment, wherein the flange male end quick connector 3 is connected by screws and an oil drain quick connector.

[0039] Quick-connect coupling 4 connects the oil hose 6 and the flange male quick-connect coupling 3, avoiding welding and facilitating disassembly or maintenance. A static grounding wire 5 connects quick-connect coupling 4, oil hose 6, and double female quick-connect coupling 8 together, forming a static discharge circuit; the static grounding wire 5 is a 4-square-meter multi-strand soft copper wire. The static grounding wire 5 is mainly used to release static electricity generated by friction with the pipeline during the transportation of oil from the metal tank through the oil hose 6 into the tank truck, ensuring electrical safety. Example 6

The two ends of the oil discharge hose 6 and the static grounding wire 5 are respectively connected by clamp 7 and double female quick connector 8 and quick connection connector 4.

[0041] As shown in Figure 1, the clamp 7 reliably connects the static grounding wire 5, the oil hose 6, and the double female quick connector 8, and reliably connects the quick connector 4, the static grounding wire 5, and the oil hose 6. This prevents oil leakage caused by loose connections during handling or storage, thus eliminating safety and environmental accidents. At the same time, it also prevents fires, explosions, and other safety accidents caused by static grounding failures and poor static conductivity.

[0042] One end of the double female quick connector 8 is inserted into the reducing quick connector 9, and the other end is inserted into the auxiliary oil hose 6. The connection is made reliably by the clamp 7 to prevent oil leakage. The double female quick connector 8 is connected to the static grounding wire 5 to improve static conductivity.
