Abstract

The utility model relates to a well-head burglar alarm of a gas well, relating to a petroleum machinery device for well-head burglar prevention of a gas well. The well-head burglar alarm comprises a shield, a burglar prevention plate, an impingement plate and a flashing board. The shield is welded on a well-head flange of the gas well, the burglar prevention plate is connected to the interior of the shield through screw threads, the impingement plate is installed at the outer side of the burglar prevention plate, and the flashing board is installed at the end part of the shield. By adopting the device, a plug is protected, a non-operator is prevented from detaching the plug to burgle gas, and rainwater is prevented from entering the shield to corrode the well-head flange, the plug and the shield. The well-head burglar alarm of the gas well can prevent gas burgling and is convenient for the maintenance of the well head of the gas well.

Description

The gas well mouth alarm

Technical field

The utility model relates to a kind of anti-theft device that is applied to the oil gas well mouth, can prevent that surreptitiously the gas person steals gas and do not influence gas well normal operation production at well head.

Background technology

At present, each oil field gas well mouth causes the certain economic loss because external environment condition is more abominable, and the lawless person often steals gas from well head, has disturbed the gas well ordinary production, has influenced the coefficient of mining of gas well to country.Each oil field worker has invented many devices that prevent to steal gas for this reason, is exactly to increase difficulty for the gas well management work but do not destroyed by the fellow-villager of locality, causes the inconvenience of work.

Summary of the invention

Can not solve surreptitiously gas and take into account in order to overcome existing anti-theft device in the gas well mouth work production.The utility model provides oil gas well mouth alarm, can prevent to steal gas and not influence the gas well normal operation to produce, and this device is made simple, easy for installation, practical.

The technical scheme that its technical problem of the utility model device solves is adopted is: it is made up of guard shield, anti-theft panel, impingement baffle, flashing board, guard shield is welded on the gas well mouth flange, anti-theft panel is by being threaded in guard shield inside, impingement baffle is contained in the anti-theft panel outside, and flashing board is contained in the guard shield end.By this device, protected plug, prevent that surreptitiously the gas person directly dismantles plug with pipe wrench; The maintenance work that this gas well mouth alarm can prevent to steal gas and make things convenient for gas well mouth.Because anti-theft panel is screwed in guard shield inside, can prevent that surreptitiously the gas person directly dismantles plug with box spanner; Secondly adorn an impingement baffle in the outside of anti-theft panel, prevent that surreptitiously the gas person is to the destruction of anti-theft panel; Flashing board is contained in the guard shield end, prevents that rainwater from entering in the guard shield, corrodes wellhead flange, plug, guard shield.

The beneficial effects of the utility model are: can prevent that surreptitiously the gas person steals gas and do not influence gas well normal operation production from gas well mouth; This device has improved the coefficient of mining of gas well for the efficient exploitation of gas well provides guarantee, prevents that a large amount of natural gases from being usurped by the lawless person, has protected national a large amount of cleaning, the energy efficiently.
