Abstract
Vákuový uzávěr s mnohonásobným účinkom je určený pre kontrolu váikua v membránových barometroch používaných pri hydrometeorologických meraniach. Podstata uzávěru spočívá v tom, že skleněná rúrka s kuželovitými zábrusmi, utěsněná v priehladnej polymérovej hadičke je z jednej strany tesne spojená s telesom vákuovej komory a z druhej strany s vákuovotesným kohútom, v ktorom je otočný kuželovitý čap s priečnym tvorom a utěsněný je maticou. Celá zostava je vákuovotesne zakrytá ochranným puzdrom, naskrutkovaným na telese vá&uovej komory, pričom jeho plniaci otvor glycerínovou náplňou je utěsněný skrutkou s tesniacou podložkou. Vákuový uzávěr s mnohonásobným účinkom možno využit všade tam, kde sa vyžaduje priebežná kontrola vákua v staničných barometroch, aleboňných prístrojoch.Multiple effect vacuum closure It is designed for the control of vacuum in membrane barometers used at hydrometeorological measurements. Essence the closure is that the glass tube with conical joints, sealed in the transparent polymer tube is one side tightly connected to the vacuum housing chamber and vacuum-proof on the other side with a tap in which it is rotatable pin with transverse and sealed is nut. The entire assembly is vacuum-sealed a protective sleeve screwed onto the body of the ventricle, while filling it the glycerine filling hole is sealed screw with sealing washer. Multiple effect vacuum closure can be used wherever required continuous checking of stationary vacuum barometers, non-powered devices.
Description
Vynález sa týká vákuového uzávěru s mnohonásobným účinkom s možnosťou trvalej kontroly vákua vo vákuovej komoře staničných membránových barometrov.BACKGROUND OF THE INVENTION The present invention relates to a multi-effect vacuum cap with the possibility of permanent vacuum control in a vacuum chamber of a stationary membrane barometer.
Doteraz sa tesnenie vákuových komor zabezpečuje pomocou sklenenej rúrky, ktorá zasahuje do vákuového priestoru prístroja. Spravidla sa po vytvoření .vyžadovaného vákua vo vákuovej komoře skleněná rúrka zataví. Nevýhodou přitom je, že v případe potřeby obnovenia vákua vo vákuovej komoře třeba zatavenú sklenenú rúrku rozbit a nahradit novou a takáto činnost vyžaduje kvalifikovaná pracovnú silu.So far, the vacuum chamber seal is secured by a glass tube that extends into the vacuum chamber of the apparatus. As a rule, the glass tube is sealed after the desired vacuum is formed in the vacuum chamber. The disadvantage here is that in the case of the need to restore the vacuum in the vacuum chamber, it is necessary to break the sealed glass tube and replace it with a new one, and such work requires skilled labor.
Uvedené nedostatky odstraňuje vákuový uzávěr s mnohonásobným účinkom, připojený na vákuovú komoru, ktorého podstata spočívá v tom, že skleněná rúrka s 'kuželovitými zábrusmi, utěsněná v priehtadnej polymérovej hadičke, z jednej strany těsné spojená s telesom vákuovej komory a z druhé strany s vákuovotesným kohútom, v ktorom je točný kuželovitý čap s priečnym otvorom, utěsněný maticou, sú vákuovotesne zakryté ochranným půzdrom, naskrutkovaným na telese vákuovej komory, pričom jeho plniaci otvor glycerínovou náplňou je utěsněný skrutkou s tesniacou podložkou.The above-mentioned drawbacks are eliminated by a multi-effect vacuum closure connected to a vacuum chamber, the glass tube having conical joints, sealed in the uppermost polymer tube, sealed on one side with the vacuum chamber body and on the other side with a vacuum-tight cock, in which the tapered pin with a transverse hole is sealed by a nut, is vacuum-sealed with a protective sleeve screwed onto the vacuum chamber body, the filling opening of which is sealed with a screw with a sealing washer.
Vynález vákuového uzávěru s mnohonásobným účinkom umožňuje trvale kontrolovat vakuum vo vákuových priestoroch staničných membránových barometrov a nedeštrukčne obnovovat vo vákuových komorách jeho vyžadovaná hodnotu. Vákuový uzávěr s mnohonásobným účinkom je v řeze znázorněný na pripojenom výkrese.The invention of the multi-effect vacuum closure allows the vacuum to be permanently controlled in the vacuum compartments of the stationary membrane barometers and undistortedly restored to the desired value in the vacuum chambers. The multiple effect vacuum closure is shown in the attached drawing in section.
Teleso vákuovej komory 1 je spojené s dvojcestným vákuovotesným kohútom 4 skleněnou rúrkou 2 opatřenou z dvoch stráň kuželovitým zábrusom. Skleněná rúrka 2 je vsunutá a utěsněná v priehladnej polymérovej hadičke 3. Kuželovitý čap 5 dvojcestného vákuovotesného kohúta 4 má v strednej časti prevřtaný otvor 6 a je otočný okolo svojej pozdížnej osi. Kuželovitý čap 5 sa utěsňuje prltiahnutím matice 7. Ochranné púzdro 8 je naskrutkované na telese vákuovej komory 1. Plniaci otvor ipre glycerínová náplň 11 v ochrannom púzdre 8 je utěsněný skrutkou 9 s tesniacou podložkou 10. Pri obnovovaní vákua vo vákuovej komoře 1 sa najskor odskrutkuje skrutka 9 ra vyleje glycerínová náplň 11, ktorá vákuovotesne izoluje uzávěr od okolitej atmosféry. Ďalej sa odskrutkuje ochranné púzdro 8, vyhotovené z plexiskla. Kuželovitý čap 5 sa natočí o 90° a připojí sa vákuové čerpadlo na vákuovotesný kohút 4. Po vytvoření potřebného vákua sa tesniaee zariadenie v opačnom poradí zloží do původnej zostavy. Stav vákua vo vákuovej komoře 1 sa priebežne kontroluje pomocou vysoko napěťového Teslovho transformátora, ktorého závit sa přiloží na skrutku 9, ktorá je v trvalom eleiktrickom kontakte prostredníctvom vákuovotesného kohúta 4 5 vákuovou komorou 1. Podlá zafarbenia elektrického oblúka, ktorý sa vytvoří v sklenenej rúrke 2 možno cez ochranné púzdro 8 vyhotovené z plexiskla určit hodnotu vákua vo vákuovej komoře 1. V súčasnosti sa v barometroch vyžaduje vakuum v rozsahu 1 až IO-2 Pa. Vákuový uzávěr s mnohonásobným účinkom možno uplatnit všade tam, kde sa vyžaduje priebežná kontrola vákua v staničných barometroch, alebo iných prístrojoch.The chamber of the vacuum chamber 1 is connected to the two-way vacuum-tight cock 4 by a glass tube 2 provided with a conical ground-glass joint of two. The glass tube 2 is inserted and sealed in a transparent polymer tube 3. The conical pin 5 of the two-way vacuum-tight cock 4 has a hole 6 in the middle and is rotatable about its longitudinal axis. The tapered pin 5 is sealed by the nut 7 being secured. The protective sleeve 8 is screwed onto the housing of the vacuum chamber 1. The filling orifice 11 for the glycerine filling 11 in the protective sleeve 8 is sealed with a screw 9 with a sealing washer 10. 9a and 7a, the glycerine cartridge 11 is poured out, which vacuum-insulates the cap from the ambient atmosphere. Next, the protective sleeve 8 made of plexiglass is unscrewed. The tapered pin 5 is rotated 90 ° and the vacuum pump is connected to the vacuum-tight cock 4. After the necessary vacuum has been created, the seal is folded back into the original assembly. The vacuum state of the vacuum chamber 1 is continuously checked by means of a high voltage Tesla transformer, the thread of which is applied to the screw 9, which is in permanent electrical contact by means of a vacuum-tight tap 4 of the vacuum chamber 1. According to the color of the electric arc formed in the glass tube 2 it is possible to determine the vacuum value in the vacuum chamber 1 through the plexiglass protective sleeve 8. At present, a vacuum in the range of 1 to 10 -2 Pa is required in the barometers. Multiple effect vacuum closure can be used wherever continuous vacuum control is required in station barometers or other instruments.
