RU85598U1 - INDEX OF POSITION OF THE LOCKING AUTHORITY OF PIPELINE FITTINGS - Google Patents

Abstract

The utility model relates to mechanical engineering, in particular to valve engineering, and in particular, to the position indicators of the stop valve of the pipe fittings and can be used in shut-off, control and throttle pipe fittings.

The technical problem solved in the claimed device is the creation of an indicator of the position of the locking body TA visually observable and reliably protected from atmospheric precipitation.

The problem is solved in that the casing is made transparent and solid, for example, of polyethylene terephthalate with a scale for the position of the locking element, and an arrow disk is mounted on the end of the spindle, the scale contains markings not only of the final, but also intermediate positions of the locking element, and between the arrow disk and the end spindle mounted shims.

Description

The utility model relates to mechanical engineering, in particular to valve engineering, and in particular to the position indicators of the shutoff valve of pipe fittings (SLT) and can be used in shutoff, regulating and throttle SLT.

Known pointer TA locking element (see RU 70910 U1 F16K 31/50), made on the flats of the TA spindle with the position marking “O” open, “Z” closed, read relative to the end of the running nut of the control spindle TA.

The disadvantages of the known device include the spindle insecurity from the effects of precipitation, the possibility of the formation of frozen sag on the threads of the spindle thread, which complicates the process of closing the TA, and therefore reduces its reliability.

Also known is the position indicator of the locking member TA (see RU 2229647 C2 F16K 3/02) a prototype consisting of a metal casing fixed to the running sleeve and provided with two opposing slots on the edges of which are marked “O” - open and “Z” - closed relative which reads at the end of the spindle the position of the locking element.

The disadvantages of this device should also include the vulnerability of the threaded part of the spindle against precipitation and the formation of frozen plugs between the spindle and the casing, which complicates not only the process of opening (closing) the TA and cleaning the threaded part of the spindle from dirt, but also the reading of the intermediate positions of the shut-off element TA.

The technical problem solved in the claimed device is the creation of an indicator of the position of the locking body TA visually observable and reliably protected from atmospheric precipitation.

The problem is solved in that the casing is made transparent and solid, for example, of polyethylene terephthalate with a scale for the position of the locking element, and a disk arrow is mounted on the end of the spindle, the scale contains markings not only of the final but also intermediate positions of the locking body and between the arrow disk and the end spindle mounted shims.

Figure 1 shows a longitudinal section of a pointer to the position of the locking member TA; figure 2 protective casing of the pointer with the marking of the provisions of the locking body; figure 3 option mounting casing in figure 1.

The position indicator of the locking member TA contains a transparent casing 1, for example, made of polyethylene terephthalate, mounted on a nut 2 of the flywheel 3 mounted on the running sleeve 4 controlled through spindle 5 by the locking member TA, mounted on the end face of the spindle 5 through the disk 6 arrows. the casing 1 is marked with a scale 8 with marking of the final and intermediate positions of the locking member TA. Between the casing 1 and the nut 2 is installed a sealing ring 9.

Assembly and adjustment of the position indicator of the locking element.

After assembling the shut-off valves with a sliding spindle, the arrow disk 7 is attached to the end of the spindle 5 with the TA shutter closed. (If the casing 1, the scale 8 is painted, the arrow disk 7 is installed through the shims 6) On the nut 2 or running the sleeve 4 is pre-installed casing 1, on which is applied a temporary subsequently erasable mark. Then, a transparent scale 8 is glued onto the inner surface of the casing 1 so that the scale number “O, O” of the “closed” position coincides with the time stamp.

After that, the casing 1 is fixed through the seal 9 either on the nut 2 or on the running sleeve 4.

The pointer is ready to go.

In whatever place the TA locking element is located relative to the arrow disk 7, the position on the scale 8 is easily read out, where it is visible in which part of the TA passage the locking element is currently located.

If the scale 8 on the casing 1 is painted, then the coincidence of the disk-arrow 7 with the number “O, O” of the “closed” position is made by selecting the adjusting washers 6.

Thus, the use of a transparent casing not only helps to protect the threaded surface of the spindle from contamination, but also increases the amount of visual observation of the position of the arrow disc relative to the scale applied to the transparent casing, which undoubtedly enhances the consumer properties of the TA with this indicator of the position of the locking element.
