Description

Sampling valve anti-theft lock device

Technical field

This utility model relates to outdoor anti-theft device, specifically a kind of sampling valve anti-theft lock device.

Background technology

At present, most producing wells is in order to enroll oil sample data, and sampling installed by the generally vertical conduit in production wellhead flow process Valve carries out admission operation.Existing sampling valve on hole top generally uses DN15 ball valve, owing to this valve does not possess anti-theft feature, therefore Stolen molecule can carry out stolen by opening sampling valve.While oil steathily, also can put because of to sampling mishandling the causing of valve Oil, this not only causes crude oil loss, but also meeting is because draining the oil pollution environment.But it is very to existing sampling valve, the most corresponding Security implementations can limit its open, bring the biggest puzzlement to oil field.

Summary of the invention

The purpose of this utility model, it is simply that for solving the problem that prior art exists, and it is antitheft to devise a kind of sampling valve Locking device, rational in infrastructure simply, prevent stolen molecule from utilizing sampling valve of producing well top to carry out stolen, thus protect crude oil the most impaired Lose, it is to avoid because stolen causes environmental pollution.

The technical solution of the utility model is: a kind of sampling valve anti-theft lock device, is arranged on sampling stealingproof sleeve outside valve, It is provided with anti-theft lock in described stealingproof sleeve；Described anti-theft lock includes shaft core, and one end of shaft core is provided with circular platform, in platform The heart is provided with rotating shaft, and rotating shaft is provided with sheet for bottle lid；Described sheet for bottle lid is provided with open hole, fixing in the platform below of open hole There is rotation nut；The other end of described shaft core is provided with the antitheft core handle of protrusion；In the inner chamber of described stealingproof sleeve, bottom is sampling valve Switch；On described stealingproof sleeve inwall, the switch at sampling valve is arranged over the anti-theft plate that two-layer is parallel；Described anti-theft panel is Circular ring plate, the intermediate sleeve of circular ring plate connects anti-theft lock.

Described stealingproof sleeve is cylindrical casing.

The axis of described cylindrical casing is vertically arranged with the pipeline of sampling valve.

Core mouth is had with antitheft core mutually coincideing on the interior side ring of described anti-theft panel.

Described anti-theft panel includes one-level anti-theft plate, two stage anti-theft baffle plate, and the core mouth direction of described two-stage anti-theft panel is mutual It is crisscross arranged.

Described sheet for bottle lid is provided with the fascination hole that multiple position is different.

The beneficial effects of the utility model can be drawn by such scheme: owing to covering one on the basis of original sampling valve Individual cylindrical stealingproof sleeve, the port at stealingproof sleeve is installed anti-theft lock, is blocked sampling valve by anti-theft lock.So sample valve When not sampling, due to the closure of theftproof lock, can effectively prevent stolen molecule from opening sampling valve stolen.When needs sampling admission money During material, first rotate the sheet for bottle lid of theftproof lock, make the open hole on sheet for bottle lid and the rotation nut aligning in shaft core, will set Barrel spanner stretches into the rotation nut blocked in shaft core and rotates shaft core, and the antitheft core bottom such shaft core turns together following Dynamic, when antitheft core is time consistent with the core mouth on first order anti-theft plate for the direction rotated, by the shaft core of theftproof lock to overcoat Move outside port, when moving on to the position of two stage anti-theft baffle plate outside shaft core, owing to the core bore locality of two-stage anti-theft plate differs Sample, needs to continue to rotate shaft core and makes antitheft core during with the core mouth position consistency of two stage anti-theft baffle plate, continue outer shifting and can prevent Steal lock and take out stealingproof sleeve.Open sampling valve by specific purpose tool more just can be sampled.The method utilizing taking-up after sampling Reversely being put into by anti-theft lock and rotating shaft core carries out antitheft.By this device so that the illegal mining oil phenomenon of sampling valve obtains pole Big improvement, and this programme simple in construction, cost of manufacture is low, it is not necessary to special configuration lockset and key, moreover it is possible to limit non-specially Industry personnel open, and have higher practical value.

As can be seen here, this utility model compared with prior art has substantive distinguishing features and progress, its useful effect implemented Fruit is also apparent from.

Accompanying drawing illustrates:
