Problems solved by technology

When draining oil, usually use a thin iron rod with a pointed end to squeeze into the side of the one-way valve. The pointed end of the thin iron rod will lift the steel ball in the one-way valve to realize the oil discharge. It is easy to damage the one-way valve, causing unnecessary economic losses
With this oil discharge method, the engine oil will often flow to t

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0019] Oil sump one-way valve type oil plug fast oil drain device, such as figure 1 As shown, it includes an elbow 1 with a curvature of 90°. One end of the elbow 1 is welded to a body 2. The body 2 is a hollow spherical structure. Elbow 1. A hollow tubular mandrel 3 is fixed vertically inside the body 2 , and the connection between the mandrel 3 and the body 2 is also sealed and welded. The top end of the mandrel 3 is open and the bottom end is closed. The part of the upper end of the mandrel 3 exposed to the body 2 is provided with an external thread. The external thread of the mandrel 3 matches the internal thread of the oil drain seat 7 of the oil pan 11, so Connect to the inner hole of the oil drain seat 7 by threads. The part of the mandrel 3 included by the body 2 is provided with two round holes 6 , the two round holes 6 are of the same size and opposite to...

Abstract

The invention discloses a rapid oil drain device with a one-way valve type oil plug of an oil pan, and the rapid oil drain device is applied to oil drainage of a diesel engine oil pan. One end of an elbow pipe is connected with a body which is shaped like a ball and hollow, and the elbow pipe is communicated with the interior of the body; a mandrel which is shaped like a hollow pipe and is closed at the bottom end is fixed on the interior of the body in the vertical direction, an inner hole of an oil drain hole seat of the oil pan is connected with the portion, exposed out of the body, of the upper end of the mandrel through an external thread, two round holes are formed in the portion, located in the body, of the mandrel, the lower end of the mandrel is closed, and a screw which is provided with a handle is connected with the center of the closed end through an internal thread. The mandrel is in threaded connection with the screw, when oil drainage is conducted on the oil pan, the screw jacks up a steel ball in a one-way valve, and engine oil can flow down. The exterior of the top end of the mandrel is provided with an external thread, the mandrel can be connected with the oil plug of an oil drain valve through the external thread, and therefore the whole device can be fixed on the oil pan conveniently; oil can be drained automatically after the oil drain device is installed on an oil drain hole, and oil drainage is more efficient and rapid.

Description

technical field [0001] The invention relates to an oil draining device for a fuel tank, in particular to an oil draining device for a diesel engine oil pan. Background technique [0002] The oil in the diesel engine of special vehicles is required to be released at a high temperature of 80-90°C, and the oil plug of the oil sump of the diesel engine of special vehicles adopts a one-way valve. An oil drain seat is arranged on the bottom surface of the fuel tank bottom shell, and the oil drain seat is fixed on the bottom surface of the fuel tank bottom shell. An oil drain seal ring, a steel ball and a spring for tightening the steel ball are arranged in the oil drain seat, and the spring holds the steel ball The ball presses against the sealing ring, sealing the oil in the tank. When draining oil, usually use a thin iron rod with a pointed end to squeeze into the side of the one-way valve. The pointed end of the thin iron rod will lift the steel ball in the one-way valve to re...
