RU61850U1 - DEVICE FOR AIR FLOW REGULATION - Google Patents

Abstract

The utility model relates to the field of ventilation, in particular to devices for extracting air from rooms.

A device for controlling air flow comprises a housing 1 and trellis plates 2 and 3 mounted on the housing. The device is equipped with a “blinds” type lattice 4, guide grooves 5 for the pins 6 that are mounted on the housing are made in the lattice plate 3, the second lattice plate 2 is fixedly fixed in the pins 6, the housing has an angular groove 7 around the perimeter and a lattice of the type "Blinds", and between it and the body placed both lattice plates. The control handle 8 is attached to the movable grid plate 3.

Using the handle 8, the plate 3 is shifted left or right, closing or opening the device or adjusting the amount of flow in it.

The proposed device is simple in manufacture, installation and operation, allows you to fully control the air flow in the ventilation duct at the exit from the premises. Fig. 2.

Description

The invention relates to the field of ventilation, in particular to devices for ventilation of premises.

A device for regulating the air flow in the ventilation channel of the room, containing a fixed and at least one movable plate with holes mounted on the rails (see USSR author's certificate No. 128595, F 24 F 13/08, publ. 1960).

A disadvantage of the known device is the inability to turn it on or off in the presence or absence of air flow in the ventilation duct, i.e. in this case, the known device is uncontrollable.

A device for regulating air flow, adopted for the prototype, containing a housing and lattice plates mounted on the housing (see USSR author's certificate No. 826153, F 24 F 13/08, publ. 1981).

The known device is also impossible to forcibly turn on or off, regardless of the presence or absence of air flow in the ventilation duct. In addition, in the work of the known device increases its size due to deviations of the air flow towards the lattice plates on the rails.

The technical result of the proposed utility model is the creation of a device for regulating air flow, the operation of which can be controlled regardless of the presence or absence of air flow in the ventilation duct, especially when extracting air from the room.

The essence of the utility model as a technical solution is expressed in the aggregate of the following features.

A device for controlling air flow comprises a housing and lattice plates mounted on the housing. The device is equipped with a “blinds” type lattice, in one of the lattice plates there are guide grooves for the pins that are installed on the housing, the second lattice plate is fixedly fixed in the pins, an angular groove is made in the housing around the entire perimeter and a “blinds” type lattice is installed in it, and between it and the body are placed both lattice plates.

Figure 1 shows a cross section aa of the device of figure 2, and figure 2 is a side view of the device in figure 1 along arrow B. The arrows show the direction of flow, the crosses indicate closed holes.

A device for regulating the air supply comprises a housing 1 and lattice plates 2 and 3 mounted on the housing 1. The device is equipped with a lattice of the “blinds” type 4, in the lattice plate 3 there are guide grooves 5 for the pins 6, which are installed on the housing 1, the second lattice plate 2 is fixedly fixed in pins 6, an angular groove 7 is made in the housing 1 around the entire perimeter and a “blinds” type 4 lattice is installed in it, and both lattice plates 2 and 3 are placed between it and the housing 1. In addition, to the plate 3, which made guides grooves 5, attached control knob 8.

The operation of the device for regulating air flow is as follows.

To fully open the device, the trellis plate 3 (see FIG. 2) is taken to the right until it stops in the pin 6 using the handle 8, an air flow passes through the device, changing its direction on the "blinds" type grating. When the device is completely closed, handle 8 is turned to the left until it stops. Air exhaust from the room stops. If necessary, it is possible to partially block the air flow without completely shifting the trellis plate 3.

The proposed device is simple in manufacture, installation and operation, allows you to fully control the air flow in the ventilation duct at the exit from the premises.
