Abstract

The utility model relates to a sealed loading swing arm used for a tank truck, comprising a vertical column, a liquid-phase rotary adapter, an air-phase rotary adapter, a short arm, a balancing device, a long arm, a vent-pipe bracket, a vacuum breaker and a vertical tube. The utility model is characterized in that a seal plug matched with a tank mouth of the tank truck is arranged on a flexible vertical tube, and the seal plug is formed by combining a metal seal plug body and a rubber sleeve; a vent-pipe and a liquid level alarm are arranged on the seal plug, and the vent-pipe is arranged at an upper end of the seal plug, a liquid level informer is arranged at a lower end of the seal plug, and the liquid level informer is connected with a liquid level informer port on the seal plug. The vertical tube is two flexible bushings. The utility model adopts the seal plug on the flexible vertical tube to be fixed on a special position of the flexible vertical tube. When in work, the seal plug and the tank mouth are sealed and the flexible vertical tube is used for adapting to tank trucks of different heights, so as to guarantee that no oil gas volatilization exists around the tank mouth and to reduce the oil waste, not only safety can be guaranteed but also the environment can be protected.

Description

A kind of truck tanker hermetic type entrucking oil filling riser

Technical field

The utility model relates to a kind of truck tanker closed loading oil filling riser, and it is the device that the truck tanker charge of oil is used.

Background technology

Existing loading and unloading arm all is that nanubrium inserts tank car, and open type is loaded and unloaded oil plant to tank car, causes oil gas to volatilize in a large number from the oil tank mouth, not only loss oil product, and, along with constantly gathering of oil gas, exist great potential safety hazard.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned defective, and the hermetic type loading arm of a kind of safety simple in structure, safe and reliable, easy and simple to handle, favourable and environmental protection is provided.The technical solution of the utility model: a kind of truck tanker hermetic type entrucking oil filling riser, it comprises column, liquid phase swivel joint, gas phase swivel joint, galianconism, balancing device, long-armed, exhaust pipe support, vacuum breaker and vertical tube, it is characterized in that: described telescopic vertical pipe is provided with an airtight plug that matches with truck tanker jar mouth, and its airtight plug is to be assembled by airtight plug body of metal and rubber coating; Described airtight freeing pipe and the liquid level alarm of being provided with beyond the Great Wall, freeing pipe is positioned at airtight end beyond the Great Wall, its freeing pipe one end is to be connected with airtight exhausr port beyond the Great Wall, the other end and gas phase swivel joint are joined, the liquid level signalling generator is positioned at airtight plug lower end, and its liquid level signalling generator is to be connected with airtight liquid level sender mouth beyond the Great Wall; Described vertical tube is telescopic two sleeve pipes.The effect of freeing pipe: when irritating oil to tank truck, because original gas-phase space replaces by fluid gradually, and the tank car mouth is a fully enclosed, and the gas of compression is discharged through freeing pipe, is discharged to device for recovering oil and gas or concentrates through pipeline to be discharged to the high-altitude safe place; The effect of liquid level alarm is: when the liquid level of tank car is more and more higher during up to liquid level contact liquid-level probe, liquid level alarm will send sound and light alarm and cut out to tank truck gas filed electromagnetic valve (adjustable height of probe); The effect of telescopic vertical pipe: because the big low height of tank car is different, according to code requirement, vertical tube should be inserted into the tank car bottom during hair oil, prevents the generation of static, and telescopic vertical pipe just can adapt to various different vehicle, its outer tube is fixed, interior pipe can be up and down in outer tube, and during hair oil, interior pipe is under the impact of oil pressure, pipe stretches out in making, and reaches the tank car bottom; After hair oil finished, interior pipe shrank under the effect of counterweight forces, was reduced to outer tube the inside.Regardless of tank car size height, both can guarantee airtight plug and Jar opening sealer like this, can guarantee again that vertical tube was inserted into the tank car bottom.

The utility model main points in design: be that airtight plug is set on telescopic vertical pipe; airtight plug is fixed on ad-hoc location on the flexible nanubrium; during work; airtight plug and the sealing of tank car mouth; telescopic vertical pipe adapts to different size height tank cars, thereby guarantees near the no oil gas volatilization of oil tank mouth, has reduced the loss of oil product; both guarantee safety, protected environment again.
