Novel standard metal measuring vessel with double-layer structure and internally-clamped heat insulation layer for testing oiling machine

Abstract

The invention disclsoes a novel standard metal measuring vessel with a double-layer structure and an internally-clamped heat insulation layer for testing an oiling machine, belongs to the technical field of a standard measuring vessel and aims at solving the problems that the conventional standard metal measuring vessel for testing the oiling machine is unreasonable in structural design, adopts a single-layer metal measuring vessel main body and is relatively poor in comprehensive function. According to the novel standard metal measuring vessel, an adopted standard metal measuring vessel main body has a double-layer metal plate structure and is internally provided with the heat insulation layer in a clamping way, a liquid level pipe is provided and connected with two vernier calipers form an angle being 90 degrees, an oiling gun support is movable, a pressure relief shunting flow bent pipe is installed and connected on a drainage pipe connected with the movable oiling gun support, a vent hole is formed in the drainage pipe connected with the movable oiling gun support, a liquid outlet of the pressure relief shunting flow bent pipe is connected in an overflow cover in an inserting manner, a liquid splashing prevention conical cover disc is sheathed on a drainage pipe body positioned in an inner cavity of the overflow cover, and dual-channel microcomputer thermodetectors are installed and connected in a gun outlet temperature measuring hole sleeve and an oil temperature measuring hole sleeve of the metal measuring vessel main body. The novel standard metal measuring vessel has a simple and practical structure and is suitable for testing various types of oiling machines.

Description

technical field [0001] The invention belongs to the technical field of standard measuring instruments and relates to a standard metal measuring instrument for verifying fuel dispensers. Background technique [0002] With the increasing development of the petroleum industry and the continuous improvement of standard measuring instruments, the technical requirements for fuel filling mechanical legal measuring instruments are also getting higher and higher. In the known technology, the existing standard metal gauge for mechanical verification of fuel refueling mainly consists of a single-layer standard metal gauge main body with upper and lower cones, an overflow cover, a refueling gun bracket, a catheter, a liquid level tube, a reading However, due to the limitation of its structure, its structural design is unreasonable, and its comprehensive functions such as heat preservation and impact resistance are poor. Especially in the process of on-line verification of fuel dispenser...
