Abstract

The three-way pressure taking device is equipment which is convenient for taking pressure and sampling to reduce the flow of a wellhead. It is composed of a tee body, a pressure taking pipe, a sealing cone, a sealing sleeve, a spring, a pressure taking sleeve, a screw cap and the like. The convex end of the tee body is drilled with two round holes to be connected with the sampling tube, the sampling tube is internally provided with a spring, a sealing cone and a sealing sleeve, and meanwhile, the round hole is drilled on the tube wall of the sampling tube, so that oil and water can enter conveniently, the pressure taking tube is externally connected with the internal thread of the pressure taking tube, a pressure gauge or a sampling leather tube is internally provided with the pressure gauge or the sampling leather tube, when pressure taking or sampling is carried out, the pressure taking sleeve is tightened, and oil flow can flow into the pressure taking sleeve along with a gap to carry out pressure measurement or flow into the sampling leather.

Description

The threeway pressure vessel

The utility model threeway pressure vessel is that a kind of equipment accessory that is used for oilfield especially makes well mouth of oil well miniaturization, microminiaturization, well mouth of oil well pressure sampling, and is easy to operate.

Because the well mouth of oil well equipment is various at present, when removing need of work, provide convenience also for simultaneously the stolen people, as well head pressure, sampling place, tight head all is to provide local to the stolen people, and stolen people is as long as turn round gently in these places, crude oil will run off, to today the oil field stolen very serious.Well head does not possess theftproof performance again, so just brings serious economic impact to production.

The utility model threeway pressure vessel its objective is that providing a kind of makes things convenient for well mouth of oil well pressure sampling convenient, reduces well head miniaturization, microminiaturization, has anti-theft feature simultaneously.

Owing to adopt such scheme, just can reduce well head flow process equipment, make things convenient for the pressure sampling, save cost.

The utility model threeway pressure vessel structure is such: it is made up of three-way body, pressure pipe, sealing awl, sealing shroud, spring, pressure cover, blind nut etc.Described three-way body becomes " T " font cylinder, and all there is screw thread at three tieing places in threeway; The circular not entire body of described pressure pipe, two ends are fixedly welded in the middle of the threeway side, are drilled with a small sircle hole on the pressure tube wall, make things convenient for profit to flow in the pressure pipe; Described spring is contained in inner end in the pressure pipe; Described sealing is bored coning, and the lower end is sitting on the spring, and the tip withstands in the sealing shroud; Coning empty body in the described sealing shroud becomes cylindrical outward and car has screw thread, goes up in the pressure pipe to cooperatively interact with the sealing awl; The inside and outside car of described table knot cover has screw thread, the bottom also is drilled with two circular holes, to show to tie in the cover on tensimeter or the stopple coupon during use, and then will show the knot put in stopple coupon, in tightening process, table knot cover will be boosted, when table knot cover bottom withstands on the sealing conical point, the sealing awl inwardly will be pressed, will produce the space between sealing awl and the sealing shroud like this, liquid will be under the effect of pressure along with outwards flowing in the space, by in two the aperture feed pressures table of table knot cover lower end or carry out work such as pressure measurement sampling in the stopple coupon.After sampling or having surveyed pressure, should go up blind nut, prevent that booty from entering in the stopple coupon or artificial destruction; Described blind nut has screw thread to be connected with the stopple coupon internal thread for circular and car outward, and the hole of interior brill triangle or pentagon and other non-standard shape prevents that its people from dismantling for going.

The utility model is described in further detail below in conjunction with accompanying drawing.
