Abstract

The utility model relates to an alarming anti-spilling oil gun. The alarming anti-spilling oil gun provided by the utility model is made up of a siphon pipe (1), a spring whistle (2), an oil outlet pipe (3) and an oil gun body (4), wherein the siphon pipe (1) is made of a metal pipe and is mounted at an oil outlet pipe (3) of the oil gun; and the spring whistle(2) made of copper or stainless steel is mounted in the siphon pipe (1) at the outer end of the oil outlet pipe (3). During oil filling process, negative pressure is produced in the oil outlet pipe (3), air circulation formed when air entering through the siphon pipe (1) produces whistle through a spring whistle. When the air inlet of the siphon pipe (1) is submerged under the oil level, the airflow is blocked, the spring whistle (2) stops whistling, a full oil filling can be known, not only is the waste stopped, but also part of potential safety hazards are reduced. The alarming anti-spilling oil gun belongs to an oil filling tool, which is convenient, practical, safe and reliable in use.

Description

Warning anti-overflow nozzle

Technical field

The utility model relates to a kind of warning anti-overflow nozzle.

Background technology

Nozzle is that each petrol service station carries out the oil plant can and the employed necessary tool of chargeing to vehicle.Common nozzle is the combination of flow gauge and fuel filler pipe, thereby measures the volume computational costs of the pipeline liquid of flowing through simultaneously at gas filed.And in actual refueling operation, common nozzle can only be measured the oil mass of adding and be difficult to allow the people directly discover the quick variation that pasta promotes.So just very easily take place completely to emit oil spilling, not only cause waste, also increased potential safety hazard to petrol service station.

Summary of the invention

The purpose of this utility model is to provide a kind of convenient and practical, safe and reliable warning anti-overflow nozzle.

The utility model is by siphon, the spring whistle, and oil outlet pipe, the nozzle body is formed.Wherein siphon is made with the metal tube of 2 millimeters of internal diameters, is installed in the oil outlet pipe place of nozzle, and a port is in oil outlet pipe, and another port is at one centimeter place of oil outlet pipe external distance oil outlet.The spring whistle is copper or stainless steel, and sealing is installed in the interior top of siphon of the outer end of oil outlet pipe.The spring whistle is made of circular thin-walled reed, and top, the spring whistle is the narrower gas channel that two reeds constitute, and air communication causes when crossing this passage that reed vibrates sends whistle.

During oiling, the oil of oil pump oil pumping jar, pressurization warp let-off metering device consistent lubricant pipe injects fuel tank from the fuel-displaced mouth of pipe.Because siphon has the oil outlet of an end outside oil outlet pipe, the negative pressure that produces in the oil outlet pipe makes air enter siphon by siphonal external port, and discharges from the pipe inner port, forms gas stream.When pasta arrival oiling muzzle place, pasta has flooded siphonal admission port, does not have air-flow to enter, and at this moment the spring whistle has stopped whistle.Learn that thus oil fills it up with, alert stops to refuel, thereby has prevented that oil plant from overflowing.The utility model

Both having prevented waste, and solved the part potential safety hazard again, is real convenient and practical safe and reliable again oil plant can instrument

Specific embodiments

As Fig. 1, Fig. 2, shown in Figure 3, siphon (1) is made with the copper pipe of 2 millimeters of internal diameters, being installed in nozzle oil outlet pipe (3) locates, one end is in oil outlet pipe (3), one end is positioned at one centimeter place, oil outlet top outside oil outlet pipe (3). during oiling, the ejection of oil makes and produces negative pressure in the oil outlet pipe (3), making air pass through siphon (1) is positioned at the outer port of oil outlet pipe (3) and enters and form gas stream. and the spring whistle (2) are shown in Figure 3 as Fig. 2, be copper or stainless steel, sealing is installed in the pipeline of siphon (1) top that is arranged in the outer end of oil outlet pipe (3). and top, the spring whistle (2) is the narrower gas channel (6) that two circular thin-walled reeds (5) constitute, when air communication is crossed herein, cause reed vibrates, send whistle. when pasta arrives oiling muzzle place, pasta has flooded the admission port of siphon (1), has not had air-flow to enter, and the spring whistle (2) have stopped whistle. learn that thus oil fills it up with, alert stops to refuel, thereby has prevented that oil plant from overflowing.

Claims (2)

1. warning anti-overflow nozzle, form by siphon (1), the spring whistle (2), oil outlet pipe (3), nozzle body (4), of the present utility model being characterised in that: its siphon (1) is the metal tube of 2 millimeters of internal diameters, being installed in nozzle oil outlet pipe (3) locates, one end is in oil outlet pipe (3), and the other end is at one centimeter place of the fuel-displaced mouth of pipe of oil outlet pipe (3) external distance; The spring whistle (2) is installed in the top pipeline that is arranged in the outer end siphon (1) of oil outlet pipe (3).

2. warning anti-overflow nozzle according to claim 1 is characterized in that the spring whistle (2) is copper or stainless steel, and the top is the narrower gas channel (6) that two circular thin-walled reeds (5) constitute.
