Abstract

The stop valve has a plug turned through less than 90 deg. when the actuator is turned for this amount. Actuator rotation is converted into a rotary and linear movement of the plug, using cams to position the plug in relation to the seat and press it against the latter. One cam controls the first 70 deg. of plug movement, without the plug engaging the seat. The second cam controls the final closing movement/ USE/ADVANTAGE : At high temps. and pressures, reducing plug wear and force needed for operation.

Afsluiter.Stop valve.

In de industrie worden wereldwijd afsluiters gebruikt.Valves are used worldwide in industry.

Een afsluiter is een mechanisch orgaan wat aan het begin, eind of tussen een pijpleiding wordt geplaatst, teneinde de stroom in een leiding te kunnen kontroleren.A valve is a mechanical device that is placed at the beginning, end or between a pipeline in order to be able to control the flow in a pipe.

5 Eén van de soortenafsluiters welke hiervoor wordt toe gepast is een afsluiter met een kogelvormig afsluitorgaan.One of the types of valves which is used for this purpose is a valve with a ball-shaped closing member.

In de industrie een kogelafsluiter genoemd, daar deze zich karakteriseerd door het kogelvormige afsluiterorgaan, de 90° verdraaiing en de kunststof zittingen.Called a ball valve in industry, as it is characterized by the ball-shaped valve member, the 90 ° rotation and the plastic seats.

10 De nadelen van de kogelafsluiters volgens de bekende stand van de techniek zijn; dat er gebruik wordt gemaakt van kunststof zittingen of een pakket veren achter de zitting teneinde de zittingen tegen de kogel te drukken. Hierdoor wordt het draaimoment op de spindel erg hoog, de kogel wordt conti-15 nue beschadigd door verontreiniging tussen de kogel en zitting, in gesloten toestand wordt een hoeveelheid medium opgesloten wat bij temperatuurstijging kan ontploffen, doordat kunststof zittingen worden toegepast is de maximale toelaatbare temperatuur ± 180°C., doordat kunststof zittingen worden 20 toegepast is de maximale toelaatbare druk bij 180°C. ± 10 bar. Doel van de uitvinding is een afsluiter met een kogelvormig afsluitorgaan en 90° bediening te verschaffen die deze nadelen niet heeft. Dit doel wordt bereikt doordat de afsluiter vol--gens de uitvinding een nok-excenter systeem bevat.The drawbacks of the prior art ball valves are; that plastic seats or a package of springs are used behind the seat in order to press the seats against the ball. As a result, the torque on the spindle becomes very high, the ball is continuously damaged by contamination between the ball and seat, when closed, an amount of medium is trapped which can explode when the temperature rises, because plastic seats are used, the maximum permissible temperature ± 180 ° C., Because plastic seats are used, the maximum allowable pressure is at 180 ° C. ± 10 bar. The object of the invention is to provide a valve with a ball-shaped closing member and 90 ° operation which does not have these disadvantages. This object is achieved in that the valve according to the invention contains a cam eccentric system.

25 Om de afsluiter van open naar gesloten toestand te bren gen wordt de bediening no. 19-90° verdraaid. Deze verdraaiing wordt door middel van een spindel no. 16 en een excenter no.25 To move the valve from open to closed position, actuator no. 19-90 ° is turned. This turning is done by means of a spindle no. 16 and an eccentric no.

15 overgebracht op het afsluitlichaam no. 3. De draaiende beweging van het afsluitlichaam no. 3 loopt van 0 tot + 70° ver-30 draaiing. Tijdens deze verdraaiing is er geen direct contact tussen het afsluitlichaam no. 3 en zitting no. 2. Op dat moment wordt verdere verdraaiing voorkomen door de nokken A,A en is het afsluitlichaam no. 3 in possitie gebracht. Deze possi-tionering is uniek en is nog niet door anderen uitgevonden.15 transferred to the closing body no. 3. The rotary movement of the closing body no. 3 runs from 0 to + 70 ° rotation. During this rotation, there is no direct contact between the closing body no. 3 and seat no. 2. At that moment, further rotation is prevented by the cams A, A and the closing body no. 3 is brought into position. This feature is unique and has not yet been invented by others.

35 In tegenstelling tot het afsluitlichaam no. 3 draaien de ' 34 G 3 06 2 ? * - 2 - pagina 2 van 4 spindel no. 16 en de bediening no. 19 wel door tot 90° verdraaiing. Deze laatste ± 20° verdraaiing (van + 70° naar 90° wordt door het excenter no. 15 over gezet op het afsluit-lichaam no. 3 van een draaiende naar een rechtlijnige bewe-5 ging, waardoor het afsluitlichaam no. 3 met kracht tegen de zitting no. 2 wordt aangedrukt en er een absolute afdichting ontstaat.35 In contrast to the closing body no. 3, the '34 G 3 06 2? * - 2 - page 2 of 4 spindle no. 16 and actuator no. 19 through rotation up to 90 °. This last ± 20 ° rotation (from + 70 ° to 90 ° is transferred by the eccentric no. 15 to the closing body no. 3 from a rotating to a rectilinear movement, whereby the closing body no. 3 is forcefully is pressed against the seat no. 2 and an absolute seal is created.

Deze combinatie van een draaiende plus een rechtlijnige beweging binnen een 90° verdraaiing van de spindel no. 16, 10 waarbij de spindel no. 16 alleen draait en niet op en neer beweegt is uniek en is nog niet door anderen uitgevonden.This combination of a rotating plus a rectilinear movement within a 90 ° rotation of the spindle no. 16, 10 where the spindle no. 16 only rotates and does not move up and down is unique and has not yet been invented by others.
