Abstract
The utility model relates to a glass fiber reinforced plastic rotary plug valve on a well mouth of a well stopping for a long time, which is used on wells stopping for a long time and wells opening at intervals in the oil field, and is composed of a valve body 1, a rotary plug 2, a bearing 3 and a screw nut 4. The rotary plug valve has small size, light weight, the same use function and pressure resistance with the common reinforced valve; because glass fiber reinforced plastic product can not be recycled, the utility model is prevented from being dismounted and sold by thieves to realize theft protection and avoid loss of government property. The utility model is favorable to the oil well safety, and improves the effective availability of the equipment.
Description
Technical field:
The utility model relates to a kind of oil field length that is used for and stops well, a wellhead assembly that drives a well.
Background technique:
Along with the continuity of oil field development time, particularly enter after the middle and later periods, oil-well strata pressure and throughput constantly reduce, and the long bailing well that stops well and interval opening well and making production day by day increases.Yet, these can't ordinary production, can not utilize or length that utilization ratio is extremely low stops still taking at present on well, the well head that drives a well bulky production tree and other a large amount of steel systeming equipment devices.So not only cause the waste on the materials, and because its target is bigger, cause the attention of stealing the offender easily, thereby comprise that the oily and well head of valve, the case that wellsite facility is stolen and sold, destroys happen occasionally, and constitute a serious threat to oilfield safety production and national wealth.
Summary of the invention:
The purpose of this utility model is to provide that a kind of volume is little, compact structure, be beneficial to antitheft and give full play to the well top stopped for long time glass fibre reinforced plastics stopcock of existing equipment device effect.
The utility model is to realize like this.This kind stopcock is made up of valve body, cock, bearing and set screw nut, is generally that the valve body center lumen of " Asia " font is indoor to be provided with cock, and cock one side is set with bearing, and the outer end is fixed with nut screwing clamping.During use, the vertical seat of this stopcock is placed on well head tubing head upper flange or sleeve pipe big four top, and is connected and fixed, then can penetrate bolt in the valve body upper bolt hole and be connected with the wellhead assembly of its top with the bolt that penetrates in the valve body lower portion bolt hole.But this stopcock also horizontal positioned is connected and makes the oil jacket valve on the production tree and use.The unlatching of this valve, closing motion are all realized by the hexahedron that turns the cock outside.Utilize this kind stopcock can finish the same withstand voltage and function of use of common steel valve.When oil well need drag for oil production, only need dismantle and install corresponding wellhead assembly easily and get final product.
The utility model volume is little, in light weight, have the withstand voltage function of use same with common steel valve, because fibre glass product manufacture can not reclaim, the offender is unlikely to steal and sell its dismounting, thereby can be antitheft, avoids the national wealth loss, help oil security production, improve the effective rate of utilization of equipment and material.
Description of drawings:
Accompanying drawing is a general structure schematic representation of the present utility model.
Embodiment: enforcement of the present utility model is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of valve body 1, cock 2, bearing 3 and nut 4, and its structure assembled relation is as follows: be generally that valve body 1 center lumen of " Asia " font is indoor to be provided with cock 2, cock 2 one sides are set with bearing 3, and tighten with nut 4 outer end.Wherein, valve body 1 adopts epoxy resin, the synthetic glass fibre reinforced plastics that forms of carbon fiber to make, and its profile is " Asia " font, upper and lower disk symmetry, limit portion is uniformly distributed with along the circumference to fix and uses screw, the middle part lateral direction penetrating, and shape, size and cock 2 and bearing 3 of being contained in it match.Cock 2 ends are provided with turn with six sides, and the other end screw part is provided with to be connected with nut 4 uses screw thread.
