Abstract

The utility model relates to a small-diameter high-pressure pipeline thermometer protection device, which consists of a high-pressure pipeline, a square expanded pipe with a boss, a 65-degree weld, athermometer protection sleeve and a thermometer, wherein the high-pressure pipeline is welded with the square expanded pipe with the boss, the thermometer protection sleeve is welded with the square expanded pipe with the boss through the 65-degree weld and the thermometer is inserted into the thermometer protection sleeve. The utility model solves the problems existing in the prior art that the measured temperature is inaccurate because the thermometer is wound on the pipeline and the welding quality of the thermometer protection sleeve is poor. The device can be widely used for protecting the small-diameter high-pressure pipeline thermometer.

Description

Minor diameter high pressure line thermometer guard unit
Technical field:
The utility model relates to the minor diameter high pressure line thermometer guard unit that a kind of minor diameter high pressure line protection thermometer is used.
Background technology:
On oilfield pipeline and gas injection pipeline, temperature is a very important parameter, just thermometer need be set on pipeline for effectively obtaining this parameter, in the past for the high pressure line of minor diameter, what generally adopt is the method that thermometer is wrapped in the pipeline outside, and this method is measured the temperature out of true.Adopted the method for protective casing afterwards, and be about to the thermometer protective casing and insert in the pipeline, and weld with pipeline, and then thermometer was inserted sleeve pipe, this method thermometric accurately is convenient to operation again.Adopt this method more convenient, and quality is guaranteed for big inch line welding, but for minor diameter (DN<150mm), especially high pressure P N (and the pipeline of 16Mpa<PN<100Mpa), protective casing welds with pipeline and has quality problems; By reason of heavy pressure, welding assembly is thick, the welding difficulty is big; The sleeve pipe longitudinal section is pipeline internal diameter cross section 1/3-1/2, causes the liquid communication area to diminish, and the pipeline resistance increases, and makes the easily broken weldering in sleeve pipe and pipeline welding position cause leakage; And be welded corner joint between sleeve pipe and the pipeline, poor welding quality should not adopt the angle seam welding for high-tension apparatus.
The utility model content:
The purpose of this utility model provides a kind of minor diameter high pressure line thermometer guard unit, this device solves the thermometer that exists in the prior art be wrapped in pipeline thermometric out of true, the problem of thermometer protective casing poor welding quality.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of minor diameter high pressure line thermometer guard unit; be made up of high pressure line, the square enlarged tube of band boss, 65 ° of weld seams, thermometer protective casing, thermometers: high pressure line is welded to connect with the square enlarged tube of band boss; the thermometer protective casing is welded to connect by 65 ° of weld seams with the square enlarged tube of band boss, and thermometer is inserted in the thermometer protective casing.This technical scheme: square enlarged tube has adopted the method that becomes interior diameter, two ends are circular configuration, external diameter is consistent with pipeline so that welding in it, the center section diameter of this pipe fitting will satisfy more than or equal to 100mm and guarantee that this circular section deducts numerical value behind the longitudinal cross-section of thermometer protective casing more than or equal to the interior sectional area of former pipeline, can reduce the pressure loss of pipeline; The center section of this pipe fitting is a square structure, and the processing height is the round boss of 50mm therebetween, does not have thermometer protective sleeve pore in boss; Thermometer protective casing and boss adopt the butt welding welding pattern that is equivalent to backing plate, and welding fabrication is good, the welding quality height.
The beneficial effects of the utility model are: simple in structure, be convenient to implement, and dependable performance, thermometric is accurate; Because this device adopts and becomes interior diameter, has guaranteed the circulation area of fluid, reduces the pressure loss; Because thermometer protective casing and enlarged tube adopt the butt welding pattern that is equivalent to backing plate, the welding quality height, safe and reliable, temperature measurement data is accurate.

Among the figure 1, high pressure line, 2, the square enlarged tube of band boss, 3,65 ° of weld seams, 4, the thermometer protective casing, 5, thermometer.
Embodiment
In Fig. 1; minor diameter high pressure line thermometer guard unit; be made up of high pressure line 1, the band square enlarged tube of boss 2,65 ° of weld seams 3, thermometer protective casing 4, thermometers 5: high pressure line 1 is welded to connect with the square enlarged tube 2 of band boss; thermometer protective casing 4 is welded to connect by 65 ° of weld seams 3 with the square enlarged tube 2 of band boss, and thermometer 5 is inserted in the thermometer protective casing 4.
