Description
Vynález rieši snímač tlaku znečistenej a stredne zahustenej kvapalnej zmesi, ktorým je mcžné meraf tlak znečistenej kvapaliny, cementovej a vápennej suspenzíe, zmesi na báze ílov, umelýcb a prírodných živíc a stredne zahuštěných kvapalných^zmesi v nízkotlakových rozvodech. Snímač tlaku spadá do odboru meracej techniky.SUMMARY OF THE INVENTION The present invention provides a pressure sensor for a contaminated and moderately thickened liquid composition which is a measure of the pressure of a contaminated liquid, cement and lime slurry, clay, artificial and natural resin based compositions, and moderately thickened liquid compositions in low pressure distributions. The pressure sensor is in the field of measuring technology.
Existuje celý rad snímačov tlaku, ktorými je možné merať příslušné tlakové hodnoty čistých kvapalín, například odporové snímače tlaku. Ich nevýhodou je možnost 1'ahkej sedimontácie pretekajúcej suspenzie v snímači tlaku, a tým následná nevhodnost použitia pre prevádzky v baníctve, ako například pri injektáži. Ďalej je možné snímat tlak kvapaliny tenzometricky. Pre svoju zložitosť tietO' zariadenia nie celkom vyhovují! v baníctve, kde je potřebné snímat tlak injektážnej zmesi. Pri meraní tlaku injektážnej zmesi musí byť zaistené dokonalé omývanie všetkých priestorov tlakového spínača, aby nedochádzalo k sedimentácii pevných častí. Uvedené známe snímače tlaku nevyhovujú týmto pedmienkam a nie je ich možné vóbec použit pre dané podmienky.There are a number of pressure sensors that can be used to measure the respective pressure values of pure liquids, such as resistance pressure sensors. Their disadvantage is the possibility of easy sedimentation of the overflowing suspension in the pressure sensor and consequently unsuitable for use in mining operations, such as injection. Furthermore, it is possible to sense the liquid pressure by strain gauge. Because of their complexity, these devices are not entirely suitable! in mining, where it is necessary to sense the pressure of the injection mixture. When measuring the pressure of the injection mixture, it must be ensured that all pressure switch compartments are thoroughly washed to prevent sedimentation of the solids. The known pressure transducers mentioned do not comply with these conditions and cannot be used at all for the given conditions.
Uvedené nevýhody a nedostatky odstraňuje v podstatě vynález, ktorým je snímač tlaku znečistenej a stredne zahustenej kva2 palnej zmesi a jeho podstata spočívá v tom, že v mieste potřebného merania tlaku prúdiacej suspenzie je připojená do potrubia elastická válcová rúra, ktorá je zdeformovaná pomocou pása. Pás je plochou stranou položený na valcovej rúre tak. aby vytváral na rúre rovnú plochu. Pozdížna os pása je kolmá na pozdlžnu os valcovej rúry. Jeden koniec pása je otočné uchytený na čapě a druhý volný koniec je pozdížnou drážkou nasunutý na vodiaci svorník. Na základovej doske je upevněný vodiaci svorník a čap, pričom válcová rúra je pásom pritláčaná o základová došku. Působením sily vytvorenej tlakom prúdiacej kvapaliny na vytvořenu plochu sa volný koniec pása pohybuje po vodiacom svorníku.The above-mentioned disadvantages and drawbacks are essentially eliminated by the invention, which is a pressure sensor of a contaminated and moderately thickened liquid mixture, and consists in that an elastic cylindrical tube is deformed by means of a strip at the point where the pressure of the flowing slurry is necessary. The strip is flat side laid on the cylindrical tube so. to create a flat surface on the oven. The longitudinal axis of the strip is perpendicular to the longitudinal axis of the cylindrical tube. One end of the belt is rotatably mounted on the pin and the other free end is slid onto the guide bolt by a longitudinal groove. A guide bolt and a pin are mounted on the base plate, the cylindrical tube being pressed against the base by a strip. Due to the force exerted by the pressure of the flowing liquid on the formed surface, the free end of the belt moves along the guide bolt.
Ďalšou podstatou vynálezu je, že pás vo východzej polohe je položený na dorazovej matici. Pás je pridržiavaný tlačnou pružinou, nasunutou na vodiaci svorník tak, aby deformoval elastickú valcovú rúru. Pružina v predpátom stave je zaistená nastavovacou maticou, ktorá umožňuje vytvořit l'ubovolné predpátie tlačnej pružiny.It is a further object of the invention that the belt in the starting position is laid on the stop nut. The belt is held by a compression spring slid onto the guide bolt so as to deform the elastic cylindrical tube. The spring in the prestressed state is secured by an adjusting nut which allows to create any prestressing of the compression spring.
Ďalšou podstatou vynálezu je, že na pohybujúcom sa konci pása je upevněné tiahlo spojené s pohyblivým kontaktom potenciometra. Pri působení sily z tlakovej kvapalnej zmesi, tiahlo pohybuje pohyblivýmIt is a further object of the invention that at the moving end of the belt, a rod is attached to the movable contact of the potentiometer. When the force from the pressurized liquid mixture is applied, the rod moves movable

Výhodou tohto snímača~)fe -dApvne -jeho jeduoduchosf, technologicky nenáročná konštrukcia, čo má velký vplyv na spotahlivosť. Ďalšou výhodou vynálezu je schopnost snímat a tým aj merať tlak znečistěných kvapalných suspenzi!. Taktiež výhodou je schopnost snímat velký rozsah tlaku kvapalnej zmesi, čo sa dosahuje tlačnou pružinou, šířkou pása a vzájomným nastavením dorazovej a nastavoivacej matice.The advantage of this transducer is its simple, low-tech construction, which has a great impact on the consumption. Another advantage of the invention is the ability to sense and thereby measure the pressure of contaminated liquid suspensions. Also advantageous is the ability to sense a large pressure range of the liquid mixture, which is achieved by a compression spring, belt width and alignment of the stop and adjusting nuts.
Na připojených výkresoch je zobrazený příklad vyhotovenia snímača tlaku znečistenej a stredne zshustenej kvapalnej zmesi, kde na obr. 1 je pohtad v náryse a na obr. 2 je zobrazený rez bokorysu.In the accompanying drawings, an example of an embodiment of a pressure sensor of a contaminated and moderately densified liquid mixture is shown. 1 is a front elevational view, and FIG. 2 is a side sectional view.
Snímač tlaku sa vyznačuje tým, že do potrubia v uneste potřebného merania tlaku pretekajúcej kvapalnej zmesi sa připojí elastická válcová rúra 1, ktorá je zdeformovaná pásom 2. Pás 2 je plochou stranou a pozdížnou osou položený na elastická válcová rúru 1 kolmo na pozdížnu os valcovej rúry 1. Jeden konieo pása 2 je otočné uchytený na čapě 3 pomocou upevňovacleho svorníka 4. Pohyblivý koniec pása 2 ukončený pozdížnou drážkou 13 sa pohybuje po vodiaccm svorníku 5. Pás 2 je vo východzej polohe opretý o dorazová maticu 8 a pridržiavaný tlačnou pružinou 6 nasunutou na vodiaci svorník 5. Tlačná pružina 6 je v predpatom stave zaistená nastavovacou ma«^icoii»· 7.6 I$a ppkyblijyoln .kfeňeíi pása 2 je u5 peviíene, tiáhlo 10 špbjená š pohyblivým kontaktom potenciometra 9. Potenciometer 9 je připevněný na zvislej konzole 11. Na základovej doske 1:2 sú pevne připevněné čap 3, vodiaci svorník 5, zvislá konzola 11 a elastická válcová rúra 1 je pritláčaná k základovej doske 12 pomocou pása 2.The pressure sensor is characterized in that an elastic cylindrical tube 1, which is deformed by the belt 2, is connected to the pipeline in the manner of the necessary pressure measurement of the flowing liquid mixture. The belt 2 is flat and with a longitudinal axis laid on the elastic cylindrical tube 1 perpendicular to the longitudinal axis of the cylindrical tube. 1. One end of the belt 2 is rotatably mounted on the pin 3 by means of a fastening bolt 4. The movable end of the belt 2 terminated by a longitudinal groove 13 moves along the guide bolt 5. The belt 2 is supported against the stop nut 8 and retained by a compression spring 6 The compression spring 6 is pre-tensioned by the adjusting mechanism 7.6 and the belt 2 is in the main, the rod 10 is connected with the movable contact of the potentiometer 9. The potentiometer 9 is mounted on the vertical bracket 11. On the base plate 1: 2 are fixedly fixed pin 3, guide bolt 5, vertical bracket 11 and ela The cylindrical tube 1 is pressed against the base plate 12 by means of a belt 2.
Snímač tlaku pódia vynálezu pracuje tak, že vo východzej polohe — bez posobenia sily od tlakovej zmesi — je pás 2 opretý o dorazová maticu 12, čím vytvára rovnú plochu na elastickej valcovej rúre 1. Pohyblivý kontakt potenciometra 9 sa nachádza v jednej krajnej polohe. Posobením pretekajúcej tlakovej zmesi na vytvorenú rovnú plochu vo vnútri elastickej valcovej rúry 1 sa vytvoří sila, ktorá posobí prostredníctvom pása 2 proti sile vytvorenej v predpatej pružině B. Překonáním sily nastavenej v tlačnej pružině 6 sa pás 2 pootočí okolo upevňovacieho svorníka 4. Tiahlo 10 posunie po odporovej dráhe kontakt potenciometra 9, čím sa změní vzájomný poměr odporu pohyblivého kontaktu a pevného kontaktu potenciometra 9. Meraním odporu potenciometra 9 je možné vyhodnotit ako tlak pretekajúcej zmesi.The pressure transducer according to the invention operates in such a way that, in the initial position - without exerting force from the pressure mixture - the strip 2 is supported against the stop nut 12, thereby creating a flat surface on the elastic cylinder tube 1. The movable contact of the potentiometer 9 is in one extreme position. By pushing the flowing pressure mixture onto the formed flat surface inside the elastic cylindrical tube 1, a force is created which acts by means of the belt 2 against the force formed in the bias spring B. By overcoming the force set in the compression spring 6, the belt 2 is rotated around the resistance of the movable contact to the fixed contact of the potentiometer 9 is changed by measuring the resistance of the potentiometer 9 as a pressure of the flowing mixture.
Snímač tlaku podl'a vynálezu umožňuje meranie tlaku injektážnych zmesi v baníctve, meranie tlaku znečistěných a stredne zahuštěných kvapalných zmesi v stavebníctve najma v nízkotlakých rozvodoch.The pressure sensor according to the invention enables the measurement of the injection mixture pressure in mining, the measurement of the pressure of contaminated and moderately thickened liquid mixtures in construction, in particular in low-pressure distribution systems.
