Description

The invention relates to the field of automatic control and can be used in the chemical industry, in particular in the production of chemical fibers.

The aim of the invention is to expand the scope and improve the operational characteristics of the device.

Figure 1 shows a General view of the device; figure 2 is a section along G-D on an enlarged scale (image rotated); in Fig.Z - section bB in Fig.1; figure 4 is a section DD; 5 is a section EE in FIG. 1; in Fig.6 - section bb in Fig.1.

The device includes two plates 1 and 2. forming the ends of the housing and containing pipes 3 and 4 with inlet and outlet openings, respectively. The inner surfaces of these nozzles together with the inner surface of the hollow shaft 5 form a central channel through which the processed thread passes. The top plate is mounted on a plate 6, which is based on a case 7 made of plexiglass. Shutter plates 8,9 and 10 are placed in the cylindrical cavity of the casing, mounted with the possibility of axial movement on the peripheral shafts 11 in the lower part of the cup, formed by the inner surface of the plate 2 and the cylindrical walls of the casing 7, gapless to the inner surface of the plate 2, but with the possibility of movement relative to it in the plane of their rotation, and the plates 12,13 and 14 of the guiding apparatus ensure that the thread enters the central cylindrical hole formed by the recesses of the shutter plates in the reduced state And prevents its jamming between joints zat.vornyh plates. The pressure of the shutter plates to the inner surface of the plate 2 is provided by springs 15. Three peripheral gear sectors 16 are also fixed from the shafts 11, the rotation of which is communicated from the central gear wheel 17 fixed to the shaft 5. The shafts 5 and 11 are mounted in sliding bearings 18 and 19 respectively, on the plate 6. A gear sector 20 is also fixed on the shaft 5, the rotation angle of which is limited by adjustable stops 21. With the sector 20, a gear wheel 22 is mounted on the shaft 23. This shaft is located in a cylindrical polo small diameter. a housing 7, which, through fittings 24 and 25, is connected to the injection 26 and drain 27 channels, respectively. Val 23

contains blades inclined to its axis and a return spring 28 is connected to the housing. The device operates as follows.

When injecting fluid

under pressure into the cylindrical cavity of the housing (refueling mode), where a shaft with blades 23 is installed, this shaft rotates. At the same time, it tightens the return spring 26 and puts the shutter plates 8,9,10 in the position when the central channel along which the thread moves is maximally open and the fluid flow rate is maximum. Upon transition to the operating mode, the injection fluid is stopped, the spring returns the shaft with the blades to their original position, while the gate plates come together, partially blocking the channel along which the thread moves, and thereby reducing

flow rate of fluid moving along the channel. Fo 0 claims 1. A device for controlling the flow of fluid containing a housing with inlet and outlet openings, between

which are mounted with the possibility of rotation of the shutter plate, characterized in that, in order to expand the scope and improve the operational characteristics of the device, it

contains peripheral shafts installed in the housing and connected to the control drive and a guiding apparatus in the form of plates, gaplessly arranged one above the other under the outlet of the hollow shaft mounted in the housing, the inlet of which is connected to the inlet of the housing, each plate having a passage and mounted on the corresponding peripheral shaft with the possibility of rotation to align the passage holes of these plates, the housing is equipped with injection and drain channels, which enes each other, and a control actuator is installed in a channel inzhektsi- Onn shaft with blades associated with a return spring and secured to the shaft gear ,, associated with

yr

a gear sector mounted on a hollow shaft, the rotation angle of which is limited by adjustable stops, as well as a central gear wheel mounted on a hollow shaft and connected to peripheral gear sectors mounted on the peripheral shafts, while the shutter plates are provided with each hole for the passage of fluid and installed on the respective peripheral shafts in one plane under the lower plate of the guide apparatus, and the lower surfaces of the shutter plates are mated with the counter surface of the end face sknogo hole

corps.

2. The device pop. 1, characterized in that. that the fluid passage openings in the flattened position of the shutter plates are cylindrical.
