Description

MECHANISM WITH LEVEL FOR ADJUSTING LIQUID MEDIA FLOW THROUGH VALVE WITH LINEAR FLOW INPUT

The subject of the invention is a mechanism with a lever that is mechanically connected to the shut-off part of the valve and the valve insert for the linear flow of liquid media and enables the stepwise adjustment of the flow of liquid media through the valve.

A technical problem solved by the invention is the construction of a mechanism with a lever that, in a simple, very convenient and efficient way, allows the precise stepwise adjustment of the flow of liquid media through the valve at exactly the same stepped intervals from opening to closing of the valve.

Existing known technical solutions to the mechanisms for regulating the flow of liquid media through the valves only partially meet the advantages of the present invention, since they do not allow the user to make precise adjustments to the flow of liquid media. The existing mechanisms also allow continuous adjustment of the flow of fluid through the valves, stepwise adjustment of the flow of liquid media through the valves, but do not allow precise repeated adjustments of the flow of fluid through the valves. Existing mechanisms are equipped with a scale and a pointer as an indicator of the valve opening position, thus allowing the flow of liquid media to be indicated, but with its lever they do not allow repeated precise valve opening positions. The advantage of this invention with the construction solution of the precise stepwise adjustment of the flow of liquid media through the valve is therefore, in comparison with the existing design solutions, precisely in the possibility of precise repeated adjustments of the flow of liquid media.

The problem of precisely repeated possible adjustment of the flow of liquid media through the valve in the direction of flow of liquid medium "C" and in the direction "D" solves the invention of a mechanism with a lever, which is directly mechanically connected with the valve shaft to the rotary stop part of the valve in which the cartridge is located valves for linear flow of liquid medium through the valve. The invention of a mechanism with the same gear on the scale bracket as on the handle of the mechanism enables accurate matching of these gears and thus the precise position of the rotary stop portion of the valve with the valve insert. To adjust the precise flow of liquid medium through the valve, push the mechanism lever down in the "X" direction, then rotate this mechanism lever in the desired direction, and loosen it so that its teeth match the teeth of the scale carrier.

The mechanism with the lever for stepwise adjustment of the flow of fluid through the valve with the cartridge for linear flow of fluid media consists of a valve shaft 1, which is screwed into the valve body 2 and sealed with a valve body 2 with a seal 3. It is attached to the valve shaft 1. the flow scale bracket 4 and secured by a nut 5. The flow scale bracket 4 is secured against rotation by the groove 10 and the ribs 11. In the groove 10 there is a rib 12 which is on the valve body 2. On the flow scale bracket 4 there is a flow scale 18, which can be expressed in angular, flow or other units. On the carrier of the scale of flow 4 there is a tooth 19, which corresponds to the tooth 20 on the lever of the mechanism 14. A view of the precise position of the adjustment of the lever of the mechanism 14 is provided by the tab 21, which is on the lever of the mechanism

14. In the shaft guide of valve 1 there is a valve shaft 6 which is sealed with seals 7 and whose flat part 8 extends into the groove of the rotary shut-off part 9 and a plug 26 is inserted therein and prevents the valve shut-off portion 22 from being displaced. with valve insert 24. A valve mechanism 14 is housed on the upper flat section 13 of valve shaft 6, which houses the pressure spring guide 15 and the pressure spring 16. The mechanism arm 14 is secured via the pressure spring guide 15 with a bolt 17. For better glide and sealing valve shaft 6 with valve shaft 1 guide there is a bushing 25 in valve shaft 1 guide.

A mechanism with a valve arm having a cartridge for linear flow of liquid media is assembled first by inserting a sleeve 25 into the valve shaft guide 1. This is followed by inserting a valve shaft 6 with seals 7 previously inserted and a plug 26 into the valve shaft guide 1, and This is followed by the insertion of a flow scale bracket 4 onto the shaft guide 1, its position being determined by ribs 11 and a groove 10 in which the rib housing 12 of the valve housing 2 sits, and the attachment of the flow scale bracket 4 by the valve shaft guide 1 with nut 5. This is followed by the insertion of a pressure spring guide 15 with a pressure spring 16 into the handle 14 of the mechanism 14, and securing it by a valve shaft 6 by means of a screw 17.
