Abstract
An anti-theft valve for oil extraction of oil fields comprises a screw cap seat, a screw, a nut, a fixing cover and a valve. The screw is installed on the valve, the screw cap seat is fixed at the upper portion of the valve, nut inner threads are in screwed joint with screw outer threads, the nut is installed in the screw cap seat, the fixing cover covers the nut, the fixing cover and the screw cap seat are connected integrally, and the nut is provided with a hole and can be rotated only by using a special tool. Therefore, larceners cannot open the valve and achieve the purpose of stealing oil and gas. Simultaneously, the problems including security incidents, environmental pollution and the like caused by the larceners stealing crude oil and natural gas can be solved, and the anti-theft valve has remarkable economic benefit and social benefit.
Description
Technical field
The utility model is a kind of wellhead assembly equipment of oil field oil recovery usefulness, is a kind of valve for guarding against theft.
Background technology
In the floor mounted of producing well production tree, production tree plays the control oil well production, and valve is arranged on production tree; Control oil well fluid into and out of, the arbitrarily opening and closing of present head valve are when thief stolen robber gas; Just open valve and steal crude oil and natural gas, cause substantial oil and natural gas stolen, and cause security incident; Cause ground environment to pollute, cause great economic loss to the oil field.
Summary of the invention
The purpose of the utility model is a kind of valve for guarding against theft of design, makes thief can not open valve, can play the effect that prevents stolen robber gas easily, reduces the oilfield economic loss, avoids environment pollution.
The purpose of the utility model is achieved in that and comprises nut seat, screw rod, nut, fixed cap, valve; Screw rod is installed on the valve, and the nut seat is fixed on valve top, and nut inner thread and screw rod external screw thread screw; Nut is installed in the nut seat; Fixed cap covers nut, and fixed cap and nut seat link into an integrated entity, perforation on the nut.
The beneficial effect of the utility model is: need with special tool(s) ability rotating nut; So thief can not be opened valve; Can't reach stolen and steal the purpose of gas; While can avoid having remarkable economic efficiency and social benefit because of problems such as the security incident that thief theft crude oil, natural gas cause, environment pollutions.
