Quick connect flow metering device and method of operation

Abstract

A quick-connect flow metering device and its operating method include a metering body and a manual clamping mechanism. The manual clamping mechanism is located at the center of the metering body and is used for quick connection with the oil inlet port to collect the flowing oil. This invention involves manually rotating a wing nut to tighten the lever, opening a lever-type scissor structure at one end of the head, which then clamps the inner wall of the oil inlet, thus fixing the measuring cup. For disassembly, loosening the wing nut closes the lever-type scissor structure, allowing the measuring cup to be removed and the flow meter collected. In use, simply insert the device into the oil inlet and manually tighten it. This eliminates the need to disassemble or replace original parts on high-end equipment such as engines for the metering device, making it very convenient and quick. The device has a compact structure, does not alter the original structure, is manually operated, convenient and quick to use, simple to maintain, and has low operating costs.

Description

Technical Field

[0001] This invention belongs to the field of flow meter technology, and specifically relates to a quick-connect flow metering device and its operating method. Background Technology

[0002] Currently, high-end equipment such as engines require precise measurement of oil flow, but suitable metering devices are unavailable. Containers are often used for measurement, which is inconvenient to connect and cannot directly determine the flow rate. There are also no similar structures to draw upon. This leads to inaccurate metering, cumbersome operation during metering, and oil overflow during connection. Summary of the Invention

[0003] The purpose of this invention is to provide a quick-connect flow metering device and operating method to solve the problem of inconvenient flow metering in oil circuits.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick-connect flow metering device includes a metering body and a manual clamping mechanism. The manual clamping mechanism is located at the center of the metering body and is used to quickly connect to the oil circuit port to collect the flowing oil.

[0006] Furthermore, the manual clamping mechanism includes a lever-type scissor opening and closing structure, a wing nut, and a tensioning rod; an axial through hole is provided at the center of the metering body, and the tensioning rod is installed in the through hole. One end of the tensioning rod is connected to the scissor opening and closing structure, and the other end is threadedly connected to the wing nut.

[0007] Furthermore, the scissor-opening structure includes a first clamping rod and a second clamping rod. Both the first clamping rod and the second clamping rod are provided with through grooves, and sliders are provided in the through grooves. The sliders are hinged to the tensioning rods through connecting rods. One end of the first clamping rod and the second clamping rod are hinged together.

[0008] Furthermore, the two sides of the slider are engaged in the through groove, and the end of the tensioning rod is provided with a locking hole.

[0009] Furthermore, the oil circuit port has an inverted cone structure, and the top of the metering body is provided with a connection port to the small-diameter end of the inverted cone structure.

[0010] Furthermore, an end face sealing gasket is provided at the connection port.

[0011] Furthermore, a tie rod sealing ring is provided on the tensioning rod to seal against the hole wall.

[0012] Furthermore, the measuring body is a steel measuring cup or an acrylic measuring cup, and the measuring body is equipped with graduations.

[0013] Furthermore, the upper part of the metering body is equipped with oil and air outlet holes.

[0014] Furthermore, an operating method for a quick-connect flow metering device includes the following steps:

[0015] Manually rotate the wing nut to pull the lever downward, which in turn moves the slider downward, opening the lever-type scissor structure at one end of the head and tightening the inner wall of the oil passage, thus fixing the oil passage port and the metering body.

[0016] To disassemble, loosen the wing nut, pull the lever upwards to close the lever-type scissor mechanism, and then pull out the measuring cup to complete the measurement collection.

[0017] Compared with the prior art, the present invention has the following technical effects:

[0018] This invention allows manual rotation of the wing nut to tighten the lever, opening the lever-type scissor structure at one end of the head and tightening the inner wall of the oil passage, thus fixing the measuring cup. To disassemble, loosen the wing nut, the lever-type scissor structure closes, and the measuring cup can be pulled out to complete the collection and measurement work.

[0019] In use, simply plug the device into the oil line inlet and tighten it manually. The main advantage is that it eliminates the need to disassemble or replace original parts on high-end equipment such as engines to install the metering device, making it very convenient and quick. The device has a compact structure, does not alter the original structure, is manually operated, easy and quick to use, simple to maintain, and has low operating costs.

[0020] The end of the pull rod has a locking hole, which can be locked and fixed with the wing nut using a tightening screw to prevent loosening and falling off. Attached Figure Description
