CN203284197U - Novel self-sealing oil gun with emergent disengaging structure - Google Patents

Abstract

The utility model discloses a novel self-sealing oil gun with an emergent disengaging structure, comprising a gun barrel, an air inlet pipe, a gun barrel joint, a spring clamp, a steel ball, a screw, a spring, a plug valve core, a gun body joint, a gun body, an O-shaped ring, and a switch handle. The steel ball is tangent to the conical surface of the gun barrel joint under the compressing effect of the spring clamp. The spring and the plug valve core are compressed in a radial hole of the gun body joint by the screw. The gun body joint is also provided with an auxiliary valve spring and an auxiliary valve core. The novel self-sealing oil gun with an emergent disengaging structure is characterized in that when the gun barrel is taken away by the power of a vehicle, the gun barrel joint is moved outwardly under the effect of a pulling force; the conical surface of the gun barrel joint pushes the steel ball to be away from the center of a gun body joint shaft, and thereby the spring clamp is opened; the gun barrel joint drives the gun barrel to be disengaged with the gun body joint, and the gun body joint and the gun body are still connected to an oiling machine, and thereby accidents can be prevented. An air inlet is plugged by the plug valve under the effect of the spring, and thereby the oil gun can conduct self sealing. The main valve and the auxiliary valve core are closed, and thereby oil can be prevented from leaking.

Description

A kind of novel Oil gun with automatic cutoff device with the ejection escape structure

Technical field

The utility model relates to a kind of petrol service station Oil gun with automatic cutoff device, relates in particular to a kind of novel Oil gun with automatic cutoff device with the ejection escape structure.

Background technology

Oil gun with automatic cutoff device is the final terminal of oiling machine hydraulic system, it is the instrument of oil product that injects in oil tank of vehicle, oil gun requires easy to operate, delivery quality can be regulated, and is safe and reliable, because period of service is long, use the situations such as frequent, some oil gun just there will be flow few, and is not fuel-displaced, the phenomenon of not self-styled and leakage of oil.More seriously, be in automobile fuel up process at petrol service station, vehicle just is not shifted when nozzle is also extracted from the oil tank of vehicle mouth, cause vehicle to break sebific duct or forget about it fuel charger, cause the fuel oil splash and cause safety misadventure, some petrol service station, for this phenomenon, installs the Pull breaking ualve device (be commonly called as: device comes off) with ejection escape function additional on the fuel charger sebific duct of being everlasting; But in the actual use procedure of petrol service station, often occur that Pull breaking ualve comes off naturally when fuel charger works, affecting petrol station normally does business, reason is that Pull breaking ualve is installed to the sebific duct position, bear the larger gravity of external dressing machine sebific duct herein, the hydraulic efficiency impact while closing rifle or flow switch is born in inside, and the Pull breaking ualve fatiguability destroys.In addition,, because the Pull breaking ualve pull-off force arranges excessively, the defencive function that can not realize Pull breaking ualve in the fuel charger real work of Pull breaking ualve also often occurs being equipped with, break sebific duct or drag down the situation of fuel charger again and again to occur, affect the petrol station work safety.And Pull breaking ualve can not repeated usage after breaking, and only has the new product of replacing could recover to add functional oil, and maintenance cycle is longer; The fuel charger Pull breaking ualve is attached in bunkering facilities as a self contained system, has increased petrol station equipment cost and maintenance cost; The rear end, installation site of Pull breaking ualve in fuel charger (fuel charger is inner) hydraulic pressure is higher, and in the service life of inner other fuel charger spare and accessory parts of impact, rear end (oil outlet position) hydraulic pressure is lower, has reduced the bunkering facilities oil pump capacity.

Summary of the invention

The utility model on the drawback basis of the above-mentioned Oil gun with automatic cutoff device that is provided with Pull breaking ualve, is provided with that a kind of to have solved the Pull breaking ualve cost high, can not repeated usage, and the novel Oil gun with automatic cutoff device equipment that fault is many.

a kind of novel Oil gun with automatic cutoff device with the ejection escape structure described in the utility model, comprise: gun barrel, air inlet pipe, gun barrel joint, spring hoop, steel ball, screw, spring, gas-stopping valve core, rifle body joint, auxiliary valve spring, auxiliary valve core, self-styled mechanism, main valve, rifle body, O type circle, switch handle, its characteristics are: be provided with between gun barrel (1) and rifle body (14) after ejection escape structure and ejection escape from seal structure, wherein, on gun barrel, anchor fitting has the gun barrel joint, gun barrel with the gun barrel joint is connected on the rifle body by rifle body joint, gun barrel joint and middle spring hoop and the steel ball of being connected with of rifle body joint with the conical surface, and be provided with O type circle, steel ball is tangent with the conical surface of gun barrel joint under the pressuring action of spring hoop, and steel ball is in the radial hole of rifle body joint, screw is pressed on spring and gas-stopping valve core in the radial hole of rifle body joint, in rifle body joint, auxiliary valve spring and auxiliary valve core also are housed, air inlet pipe one end is fixed on gun barrel, the other end is inserted in the endoporus of rifle body joint, be provided with self-styled mechanism and main valve in the rifle body, there is switch handle rifle body inboard.

the air inlet pipe of this novel Oil gun with automatic cutoff device is connected with the upper cavity from seal structure by the aperture on the valve seat of auxiliary valve core, guarantee that in the oiling working process, the switch membrane from seal structure is in balance position, self-styled mechanism reconciles and impels main valve to close when overbalance, when gun barrel occurs to be taken away by the vehicle brute force, the gun barrel joint outwards moves under the effect of pulling force, the conical surface of gun barrel joint promotes steel ball simultaneously away from rifle body joint axis center, spring hoop is opened, the gun barrel joint is with gun barrel and rifle body splice failure, rifle body joint still is connected with fuel charger with the rifle body, avoided the generation of accident, simultaneously, gas-stopping valve core stops up induction opening under the effect of spring, realize that oil gun is self-styled, main valve and auxiliary valve core are closed, thereby prevent the fluid leakage.This novel Oil gun with automatic cutoff device, the all functions that not only have current nozzle, and possess the defencive function of Pull breaking ualve to fuel charger, installation position because of it in bunkering facilities is the nozzle position, the normal external force of bearing is less, be not prone to the protectiveness fracture under normal condition, even run into powerful external force, occur that the protectiveness fracture not there will be sebific duct to hurt sb.'s feelings yet and reveals situation with too much oil plant, highly beneficial to petrol service station operation safety; It has solved that Pull breaking ualve in the past is in vertical sebific duct deadweight external force for a long time and the fracture by fatigue phenomenon that occurs, project organization does not affect the pressure transmission of fuel charger, not there will be the phenomenon that fuel charger installs additional after Pull breaking ualve affects oil pump capacity, more be fit to the actual requirement of current petrol service station, and reduced equipment In Oil Service Station maintenance cost and restore cycle.
