Abstract

The utility model discloses a refueling exhaust funnel which comprises a funnel and an exhaust pipe, wherein the exhaust pipe is fixed on the inner wall of the funnel, an exhaust port of the exhaust pipe is arranged on an upper port of the funnel, an air inlet of the exhaust pipe is arranged on a lower port of the funnel, the exhaust pipe is fixed on the inner wall of the funnel through welding or riveting, the shape of the upper port of the funnel corresponds to the shape of the lower port of the funnel, and the shape can be round, square or other shapes. The refueling exhaust funnel has the functions of refueling and exhausting simultaneously, even when oil is filled through a refueling passage, the gas can be exhausted through the exhaust pipe outwards, and the pressure balance inside and outside a conservator container can be kept, thereby realizing rapid flow speed and none bubble overturning.

Description

The oiling exhaust funnel

Technical field:

The utility model belongs to the oiling field, relates to a kind of oiling exhaust gear.

Background technology:

In daily voltage transformer operation work, oil level detection is a big event, when oil level drops to deficiency or cannot see, just needs refueling operation, generally needs volume read-out all at 50-70KG, and quantity is bigger.Oil filler is a considerable link in refueling process, present situation is one barrel of transformer oil that amount is 10KG, when in funnel, falling oil, occur because of conservator container external and internal pressure is different oil can not be rapidly or flow velocity cross slug flow and go in the conservator container, make oiling personnel refueling time long, tired easily, reduce work efficiency.This is because funnel and conservator joint all are circular, adds oil deadweight in the upper hopper, makes both be in sealing state substantially, and the air in the conservator container can only pass through the outside exhaust of oil filler, " turning over bubble " phenomenon when just having occurred refueling.Only make it pass through certain mode and discharge gas, could guarantee that the flow velocity in the refueling process soon, does not turn over bubble, and can improve oiling efficient greatly.Carry out on voltage transformer owing to refuel, how more than 2 meters, belong to ascend operation, require control effort to get well apart from ground.Can only wait as long in original refueling process, continue refueling operation after having arranged air, occur staff's health fatiguability so easily in refueling process, the increase of the safety hazard of ascending a height has reduced work efficiency.

The utility model content:

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of oiling exhaust funnel is provided, and it is characterized in that:

Comprise a funnel 1, freeing pipe 2, freeing pipe 2 is fixed on the inwall of funnel 1, and the exhausr port 3 of freeing pipe 2 is arranged on the suitable for reading of funnel 1, and the admission port 4 of freeing pipe 2 is arranged on the end opening of funnel 1.

Freeing pipe 2 by welding or riveted and fixed at funnel 1 inwall.Funnel 1 is suitable for reading corresponding with funnel 1 end opening shape, is circular, square or other shape.

This oiling exhaust funnel is placed on the voltage transformer conservator filler neck.Have oiling and exhaust and carry out function simultaneously, promptly make simultaneously, also by the outside exhaust of freeing pipe, kept the inside and outside equilibrium of pressure of conservator container, thereby realized that flow velocity is fast, do not turn over bubble at the filling passage gas filed.

Description of drawings:

Fig. 1 is an oiling exhaust funnel structural representation of the present utility model;

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

Referring to Fig. 1, a kind of oiling exhaust funnel comprises a funnel 1, freeing pipe 2, and freeing pipe 2 is fixed on the inwall of funnel 1, and the exhausr port 3 of freeing pipe 2 is arranged on the suitable for reading of funnel 1, and the admission port 4 of freeing pipe 2 is arranged on the end opening of funnel 1.

The end opening of funnel 1 is less than suitable for reading, and during oiling, oil suitable for readingly enters, discharges from funnel 1 end opening and enter oil vessel from funnel 1, at gas filed simultaneously, gas in the oil vessel enters the admission port 4 of freeing pipe 2, and is up along freeing pipe, and gas is discharged at the exhausr port 3 of freeing pipe 2.

Funnel 1 is suitable for reading can be circular, square or other shape, and funnel 1 end opening can be circular, square or other shape, and freeing pipe 2 can be fixed on funnel 1 inwall by welding, riveted joint or alternate manner.

At first make a common funnel according to the container dimensional size.Secondly, according to the funnel inner wall shape, make a respective shapes, diameter is iron pipe or the copper pipe of 10MM, and translates into the funnel outer wall at place, funnel outer.At last the iron pipe of common funnel and respective shapes or copper pipe are fixed together with rivet.

Above content is to further describing that the present invention did in conjunction with concrete preferred implementation; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of being submitted to.

Claims

1. one kind is refueled exhaust funnel, it is characterized in that: comprise a funnel (1), freeing pipe (2), freeing pipe is fixed on the inwall of funnel (1), and the exhausr port (3) of freeing pipe (2) is arranged on the suitable for reading of funnel (1), and the admission port of freeing pipe (4) is arranged on the end opening of funnel (1).

2. a kind of oiling exhaust funnel according to claim 1 is characterized in that: freeing pipe (2) by the welding or riveted and fixed at funnel (1) inwall.
