Abstract
The present invention relates to a telescopic temperature measuring head for measuring transmission medium temperature of a buried pipeline. The present invention is characterized in that a temperature measuring head fixedly connected with the outer part of a pipeline 15 is installed in a casing13, and after passing through an isolating valve 12, the tail of the temperature measuring head 14 inserted into the pipeline 15 is connected with a spacing mechanism and a moving mechanism in series. The temperature measuring head 14 can measure the temperature field of the transmission medium in the buried pipeline and can be conveniently expanded and shrunk; a pipe cleaning device or a detector can smoothly pass through the temperature measuring head, and the temperature measuring head 14 is guaranteed to be in a very good condition. The prevent invention has the advantages of tight sealing and no leakage of the transmission medium, and provides necessary technical support for the further safe and economical operation of the buried pipeline.
Description
Technical field
The present invention is used for the expanding temperature measuring head that buried pipeline is measured the pumped (conveying) medium temperature.The measurement and the piping system technical field that relate to temperature.
Background technology
The buried pipeline particularly temperature of buried oil pipeline pumped (conveying) medium is an important parameter of traffic control, is relevant economy, safe operation deciding factor, and the temperature conditions of therefore grasping pumped (conveying) medium each point in the pipeline at any time is just necessary.Temperature measuring equipment is not installed on buried pipeline before, and just by the temperature of calculating and experience is come control medium.Under normal circumstances, do like this and can accomplish economy, safe operation, the practice of decades has also proved this point; But when fortuitous event takes place, just unreliable by calculating and experience, perhaps can have little time to handle, can bring very big hidden danger to safety, economical operation.If the temperature field of temperature measuring equipment testing conduit pumped (conveying) medium is installed along the line at regular intervals at buried pipeline, and do not influence normal pipeline pigging or pipe detection, so will science and handle safety, the economical operation of pipeline when having unexpected situation to take place reliably.
Summary of the invention
The objective of the invention is to invent and a kind ofly can carry out temperature field measurement and not influence the expanding temperature measuring head of normal pigging of pipeline and detection the buried pipeline pumped (conveying) medium.
The present invention's expanding temperature measuring head general structure as shown in Figure 1.From temperature measuring head temperature measuring head 14 afterbodys that insert pipeline 15 housing 13 are installed and are passed isolation valve 12 back serial connection position-limit mechanism and travel mechanisms.Specifically: temperature measuring head 14 afterbodys (it is preceding inserting pipeline 15 directions with temperature measuring head 14) connect front end flange 18, afterbody has externally threaded tubulose temperature measuring head connecting link 10, at temperature measuring head connecting link 10 overcoats one circular sleeve 11, these circular sleeve 11 front ends and isolation valve 12 are connected, the rear end flange 9 with temperature measuring head connecting link 10 isometrical endoporus that is connected, and form temperature measuring head mobile cavity 19 between the temperature measuring head connecting link 10, flange 18 becomes to be slidingly matched with sleeve pipe 11 inwalls, move spacingly with 9 pairs of temperature measuring head connecting links 10 of flange of the isolation valve 12 of sleeve pipe 11 front ends and rear end, constitute the position-limit mechanism of this device jointly; Connect the small casing 20 that a front end has second half flange 9 in sleeve pipe 11 backs with screw 7, small casing 20 rear ends have flange to be connected with overcoat 3, the drive nut 5 that cooperates and be fixed with driving handwheel 2 with temperature measuring head connecting link 10 is arranged in overcoat 3, and this is the travel mechanism of this device.Temperature measuring head 14 (see figure 2)s wherein are a pipe, its front end shutoff, and open rearward end and be fixed with flange forwardly is equipped with a plurality of holes of wearing temperature sensor signal output line 1 equally spacedly, and a temperature sensor 16 is installed in corresponding each hole.Temperature sensor signal output line 1 passes to handwheel 2 in the pipe of temperature measuring head 14 and temperature measuring head connecting link 10.Temperature measuring head is installed housing 13 for front end and pipeline 15 are connected, the rear end is the short tube of flange.Isolation valve 12 has city's pin product for to holding the formula ball valve under the arm.For the accumulation that reduces isolation valve 12 leakage medium builds the pressure, so that cause the leakage of back position-limit mechanism and travel mechanism, add blowdown valve 17 in the rear end of isolation valve 12, it is a needle valve, and city's pin product is also arranged.For position-limit mechanism accurately and reliably spacing, the length of temperature measuring head 14 should be slightly larger than isolation valve 12 and add that temperature measuring head is installed the length of housing 13 and the internal diameter of pipeline 15 adds a pipe thickness sum, and the length of sleeve pipe 11 is greater than pipeline 15 internal diameters and temperature measuring head 14, temperature measuring head connecting link 10 joint flange thickness sums.Like this, when the needs temperature measuring head put in pipeline 15, temperature measuring head 14 moved forward, when temperature measuring head connecting link 10 moves to the forefront, the front end of temperature measuring head 14 is against on pipeline 15 inwalls of forefront; When needs temperature measuring head 14 withdraws from, when flange 18 rear ends of temperature measuring head connecting link 10 withstand on the flange 9 of temperature measuring head mobile cavity 19 rear ends, just in time make the front end of temperature measuring head 14 withdraw from pipeline 15.Drive nut 5 has in being screw thread, middle front part that the pipe of bulge loop, bulge loop periphery and overcoat 3 inwall loose fits, drive nut 5 afterbodys and the wheel hub wringing fit that drives handwheel 2 are arranged outward.And the overcoat 3 of drive nut 5 outsourcings is thick-walled tubes, and a plurality of internal thread holes are arranged on the tube wall of front end end face, all has the small casing 20 of flange to cooperate with front and back, connects and cap seal travel mechanism with screw 6, and small casing 20 front ends are connected with sleeve pipe 11 with flange 9.Overcoat 3 rear ends are by back-up ring 21 shutoff.For avoiding medium from position-limit mechanism and travel mechanism, to leak, in sleeve pipe 11 and small casing 20 flange connecting 9 and be added with O-ring seal 8 between temperature measuring head connecting link 10 peripheries, respectively be added with O-ring seal 4 before and after drive nut 5 bulge loops between travel mechanism's overcoat 3 and drive nut 5.
As from the foregoing, this expanding temperature measuring head can be measured certain some temperature of pumped (conveying) medium in the buried pipeline or the temperature field of whole pumped (conveying) medium, temperature measuring head 14 can put in easily and carry out thermometric in the pipeline 15, also can shrink pipeline 15 easily so as to make rabbit or detecting device smoothly by guaranteeing the excellent of temperature measuring head 14, and the sealing of this expanding temperature measuring head is tight, can not cause the leakage of pumped (conveying) medium.Be further safety, the economical operation assurance that provides the necessary technical of buried pipeline.
