Transverse and longitudinal distance and angle adjustable universal oil tube apparatus of oiling machine

Abstract

The invention relates to a universal oil inlet pipe device capable of adjusting the transverse distance, the longitudinal distance, the transverse angle and the longitudinal angle for an oiling machine. The universal oil inlet pipe device for the oiling machine comprises nozzles (1), pipe bodies (5), a lock nut (4) and a pipe holder (7), wherein both the number of the nozzles (1) and the number of the pipe bodies (5) are two, with one on the upper part and one on the lower part; one ends of the nozzles are provided with external threads (1.1), and the other ends of the nozzles are provided with light pipes; one ends of the pipe bodies are provided with external threads (5.1); the light pipe ends of the nozzles (1) are inserted into the external thread (5.1) ends of the pipe bodies (5); the end parts at the other ends of the upper pipe body and the lower pipe body (5) are closed, and oil conveying openings (5.1) are arranged aside the pipe bodies; the oil conveying openings (5.1) of the upper pipe body and the lower pipe body (5) are closed by the pipe holder (7) which is longitudinally connected and fixed with the pipe bodies (5) through stay bolts (9); and the lower nozzle, the lower pipe body, the oil conveying opening aside the lower pipe body, a cavity in the pipe holder, the oil conveying opening aside the upper pipe body, the upper pipe body and the upper nozzle form a hermetical oil conveying channel (13) from the bottom to the top, When pipes are arranged on a service station, the universal oil inlet pipe device can simultaneously realize the adjustment of the longitudinal distance, the transverse distance, the longitudinal angle and the transverse angle so as to realize the aim of connecting rigid pipes.

Description

(1) Technical field [0001] The invention relates to an oil pump type oil dispenser, in particular to an oil inlet pipe device for the oil dispenser. It belongs to the technical field of fuel tankers. (2) Background technology [0002] In order to avoid unsafe hazards such as fire caused by fuel oil injection when the submersible pump type tanker is knocked down by the impact of external force, it is required to install a knock down valve on the oil inlet pipeline of the tanker. In order to ensure that the knock-down valve valve is reliably closed when the tanker falls, a hard pipe connection must be used between the tanker and the knock-down valve. [0003] In the prior art, when the submersible pump type fuel dispenser was installed, each gas station all adopted a direct hard pipe connection mode (see figure 1 ). Its disadvantages are: when the direct hard pipe is connected, the horizontal and vertical dimensions of the oil inlet nozzle pipe of the fuel dispenser and the...

AI Technical Summary

Problems solved by technology

Its disadvantages are: when the direct hard pipe is connected, the horizontal and vertical dimensions of the oil inlet nozzle pipe of the fuel dispenser and the outlet pipe of the oil delivery pipe cannot be correctly guaranteed, and it is difficult to adjust the size and angle, resulting in the gap between the connection nozzle after the fuel dispenser is installed. A large internal stress is generated between them, which reduces the service life. At the same time, the nozzle is extremely prone to oil leakage, which makes it time-consuming and laborious to install the connecting pipe, and it is difficult to ensure the connection effect.

It is especially difficult to connect pipelines when replacing fuel dispensers produced by different manufacturers at gas stations
