SU14079A1 - The index of the velocity of the fluid in the pipe - Google Patents

Description

The present invention is a pointer to the velocity of the fluid in the pipe, which consists of inserts in the latter with helical guide walls and a radial blade mounted on the spring under opposition from the spring. A part of the walls of the marked index is made of a transparent material, and corresponding divisions are applied on the envelope surrounding it.

In the drawing of FIG. 1 depicts a vertical section of the proposed indicator installed in the pipe; FIG. 2 is a detail of it (insert with helical guide walls), top view; FIG. 3 is an external view of a device for simultaneously observing the speed of movement in several pipes with a vertical section of one of the indicators.

The proposed pointer consists (Fig. 1 and 2) mainly of the insert ac with spiral-shaped guide walls b, which give the jet a spiral movement, and the blade c, which sits on the trunnions d and d. Stru, due to the spiral movement it generates the blade in, turning the latter by a certain angle, depending on the intensity of the jet's movement and the resistance of the helical, flat spring e attached at one end to the trunnion e,

And another, to the control ring fixed in the pipe. The trunnion, rotating in its sleeve h, has a stop allowing preliminary tightening of the spring e. To observe the angle of rotation of the blade in corresponding to different speeds of fluid movement in the pipe t, part of the latter is replaced by a transparent, glass cylinder and under which on embracing | corresponding to the corresponding divisions (Fig. 3). The proposed indicator, by appropriate selection of the angle of inclination of the spiral walls b and the size of the spring e, can be adapted to monitor any fluid velocity in the pipe, and can also be used to simultaneously observe the movement of fluid in several pipes from one place (Fig. 3) . In the latter case, glass cylinders and individual tubes are inserted into a frame consisting of two angles and angles attached to each other through columns n, which, however, leave access to the cylinders for the necessary illumination and convenient reading.

The subject of the patent.

1. The index of the velocity of the fluid in the pipe, characterized by the npji change placed in Zrube

c in with screw-shaped guiding walls of b and blade c, sitting on pins 2 and d and surrounded by a transparent cylinder, and under which corresponding divisions are applied to the sleeve surrounding it, the pins d of which are fastened to one spring end, the other end of which strengthened in the regulating ring g (Fig. 1-2).

2. A device for simultaneous observation of the speed of movement in several pipes with the use of the indicator described in paragraph 1, characterized in that glass tubes and individual tubes are inserted into a frame consisting of two prisms and fastened together by means of columns. n (Fig. 3).
