Abstract

Vynález popisuje systém regulácie tlakomerov so škatulovými membránami pri justáži za pomoci regulačného elementu prispojkovamého na membránu a nastavovacích skirutiek. Za pomoci týchto elementov sa přibližuje alebo oddaluje regulačná skrutka od vahadla převodového strojka, resp. sa skracuje, alebo predlžuje dráha ručičky po stupnici.The invention describes a system for regulating pressure gauges with box diaphragms during adjustment using a regulating element connected to the diaphragm and adjusting screws. With the help of these elements, the regulating screw is moved closer or further away from the rocker arm of the transmission mechanism, or the path of the pointer along the scale is shortened or lengthened.

Description

Vynález sa týká zariadenia pre reguládu tlakomerov so škatulovými membránami, ktorých reguláeia pri j ustávaní sa vykonává pomocou regulačního elementu a nastavovacích skrutiek.BACKGROUND OF THE INVENTION The present invention relates to a device for regulating pressure gauges with box diaphragms, the regulation of which during adjustment is performed by means of a control element and adjusting screws.

Doteraz známe spótsoby regulácie ťlakoímerov so škatulovými membránami spočívali v tom, že dorazový pliešok na membráně a dorazový idrótik na prevodovom strojčeku sa pri jus-táži přihýbali dovtedy, pokým tlakoměr neukazoval hodnoty v požadovanom rozsahu. Výsledek regulácie bol vždy závislý na odborností montážnika, ktorý citem pósobil na dorazový pliešok alebo drótik. Vyregulovanie celého tlakoměru pri takomto spóisoibe justovania do požadovanej toierancie bolo vel’mi prácne, pričom zmontované tlakoměry neboli rovnakej kvality.Hitherto known methods for regulating pressure gauges with box membranes consisted in that the stop plate on the diaphragm and the stop idrograph on the gearing machine were moved during the assembly until the pressure gauge was within the desired range. The result of the regulation has always been dependent on the expertise of the installer, who sensitively influenced the stop plate or wire. Adjusting the entire pressure gauge to such a level of adjustment was very laborious, and the pressure gauges assembled were not of the same quality.

Výššieuvedené nedostatky odstraňuje za.riadenie pre reguláciu podl’a vynálezu, ktorého podstatou je, že regulačný element nastavovaný vo vertikálnom smere regulačnou iskrutkou a v horizontálnem smere ďalšou regulačnou skrutkou pre predlžovanie a skracovanie ramena vahadla je prispájkovaný na membránu pre nástavovanie polohy membrány k převodovému strojčeku.The aforementioned drawbacks are eliminated by the control device according to the invention, which is based on the fact that the control element adjusted in the vertical direction by the control screw and in the horizontal direction by another control screw for extending and shortening the rocker arm is soldered to the diaphragm to increase the diaphragm position.

SUBJECT

Device for regulating pressure gauges with box diaphragms, characterized in that the control element (1) is adjusted in the vertical direction by the control screw (2) and in the horizontal direction by further control thrusts and reduces the time required to adjust the device to the desired tolerances. By acting on the control elements, the control is continuous in both horizontal and vertical directions and at the same time the adjustment is substantially accelerated.

An exemplary embodiment of the invention is shown in the accompanying drawing. Fig. 1 shows the position of the adjusting screws and FIG.

2 the mounting of the control system on the pressure gauge diaphragm.

The control element 1 brazed on the diaphragm 4 is provided with a control screw 3 for moving the rocker arm 5 of the gearbox and another control screw 2 for changing the position of its elastic part.

By actuating the adjusting screw 2, the resilient part of the element 1 is pulled or expanded, which also changes the position of the diaphragm 4 against the gear mechanism and the linearity of the pointer against the scale. By swiveling the control unit 3 to extend or shorten the arm of the rocker arm 5, the position of the element 1 relative to the center of the diaphragm 4 is changed.

The invention can be used to control mechanisms in which the arm of the control element needs to be extended in both vertical and horizontal directions.

a bolt (3) for extending or shortening the rocker arm arm (5) is soldered to the diaphragm (4) for positioning the diaphragm to the gearbox.
