Description

MECHANISM WITH A BUTTON FOR CONTINUOUS FLOW CONTROL OF LIQUID MEDIA THROUGH A VALVE WITH A LINEAR FLOW INPUT

The object of the invention is a mechanism with a knob, which is mechanically connected with 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 design of a push-button mechanism that allows a simple, very convenient and efficient way to fine-tune 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 satisfy the advantages of the present invention, since they do not allow the precise, if desired, repeated adjustments of the flow of liquid media. The existing mechanisms also allow continuous adjustment of the flow of liquid media through the valves, stepwise adjustment of the flow of liquid media through the valves, but do not allow precise adjustments of the flow of fluid media at the request of the valve user. Existing mechanisms are equipped with a scale and a pointer as an indicator of the valve opening position, thus providing an indication of the size of the flow of liquid media, but do not allow precise repeated valve opening positions. The advantage of the present invention with the construction solution of the precise stepwise adjustment of the flow of liquid media, in comparison with the existing design solutions, is precisely 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 a valve is solved by the invention of a push-button mechanism, which is directly mechanically connected with the valve shaft to a rotary shut-off part of the valve in which there is a valve insert allowing linear flow of liquid medium through the valve.

The invention of the mechanism with the same gear on the scale carrier as on the handle of the mechanism allows accurate matching of these gears, and thus the exact position of the rotary shut-off of the valve with the valve insert. To adjust the precise flow of liquid medium through the valve, push the mechanism knob down in the "X" direction, then rotate this knob in the desired direction and loosen it so that its teeth match the teeth of the scale carrier.

The mechanism with the button for stepwise adjustment of the flow of liquid media through a valve with a cartridge for linear flow of these media consists of a shaft guide of valve 1, which is screwed into the valve body 2 and sealed with the valve body 2 by the seal 3. The flange 9 of the valve body 2 is a flow scale bracket 4 is attached, which is secured by two screws 5, a safety washer 6, and nuts 7 to the flange 9 of the valve body 2. The flow scale bracket 4 has a flow scale 10 which can be expressed in angular, flow or other units. On the scale carrier • · flow 4, there is a pinion 11 that matches the pinion 12 on the arms 13 of the knob 14 of the mechanism 14. A view of the precise position of the knob setting of the knob 14 is provided by the tab 15 on the knob 14.

In the shaft guide of valve 1 there is a valve shaft 16, which is sealed with seals 17 and whose flat part 18 extends into the groove 29 of the shut-off part of the valve 19 and a plug 20 inserted into the hole 31 prevents the shut-off part of the valve 19 from being displaced. with valve insert 30.

On the square portion 21 of the valve shaft 16 is a mechanism knob 14 in which a pressure spring is located 22. The vertical stroke of the mechanism knob 14 is limited by the spacer ring 23 which is mounted on the valve shaft 16. In the square hole 24 of the mechanism knob 14 there is a guide screw bushing. 25, which is guided by a screw 8 on which the washer 26. For better sliding and sealing of the shaft of the valve 16 with the guide of the shaft of the valve 1, there is a bushing 27 in the guide of the shaft of the valve 1.

The mechanism with a valve button having a cartridge for the linear flow of liquid media is assembled by first inserting a sleeve 27 into the valve shaft guide 1 followed by the insertion of a valve shaft 16 with pre-inserted seals 17 and a plug 20 into the valve shaft guide 1 with the sealed gasket 3 and screwing it into the valve body 2 by means of a hexagonal attachment 28 into the valve body 2.

This is followed by the installation of the flow scale bracket 4 on the flange 9 of the valve body 2 and the mounting with two screws 5, lock washers 6 and nuts.

7. This is followed by the insertion of a spacer ring 23 on the shaft of the valve 16, and the insertion of a pressure spring 22 with a mechanism knob 14 and a guide sleeve 25 of the valve 16. This is followed by screwing a mechanism button 14 with a screw 8 with a washer 26 through the guide sleeve 25 in valve shaft 16.
