RU221627U1 - Sprinkler atomizer, installed with the bulb facing up - Google Patents

Abstract

The utility model relates to the field of fire extinguishing, namely to devices designed for spraying a fire extinguishing agent. The sprinkler atomizer, installed with the bulb upward, includes a hollow body designed to be connected to a pipeline in its lower part; a rod is installed in the upper part of the body, in which the thermoflask is fixed, while spray channels are formed in the body, on one side communicating with the internal cavity of the body , and on the other side having an exit to the outside, and the smallest angle between the axis of each spray channel and the vertical axis of the sprayer is less than 90°. The technical result of the claimed utility model is to increase the fire extinguishing efficiency of a sprinkler nozzle installed with the bulb facing upwards.

Description

The utility model relates to the field of fire extinguishing, namely to devices designed for spraying a fire extinguishing agent.

Fire extinguishing installations use sprinklers that differ in position during installation and the shape of the socket [Electronic resource: https://opozhare.ru/faq/osobennosti-i-raznitsa-orositelej-sprinklernyh-rozetkoj-vverh-i-vniz.

the convex sprayer is designed to distribute the water flow directed upward;

a flat or concave nozzle breaks up the downward flow.

The SVV (vertically upward) sprinkler socket is a thick brass round plate that is securely attached with two arms to the top of the sprinkler body. The slits along the edge of the rosette, forming the petals, are designed to break the water flow into drops. The rosette petals formed by the slots always point downward, regardless of the type of sprinkler.

The spray channel in the SVV sprinkler is directed upward and when the sprinkler is activated, the flow of substance comes out upward and is directed to the socket, which serves as a flow breaker and directs it down to the source of fire.

The disadvantage of the known solution is the low efficiency of extinguishing the source of fire, since the flow of the substance takes more time to reach the source of fire, because the spray channel is directed upward and therefore the flow is first directed upward and then refracted by the rosette so that its droplets change their direction downward towards the source.

The technical result of the claimed utility model is to increase the fire extinguishing efficiency of a sprinkler nozzle installed with the bulb facing upwards.

The specified technical result is achieved due to the fact that the sprinkler sprayer, installed with the bulb upward, includes a hollow body configured to be connected to a pipeline in its lower part; a rod is installed in the upper part of the housing, in which the thermoflask is fixed, while spray channels are formed in the housing , on the one hand communicating with the internal cavity of the housing, and on the other hand having an exit to the outside, and the smallest angle between the axis of each spray channel and the vertical axis of the sprayer is less than 90°.

Thus, the combination of essential features of the claimed utility model makes it possible to increase the fire extinguishing efficiency of a sprinkler atomizer installed with the bulb upward, since the direction of the spray channels downward ensures that the substance quickly reaches the source of fire. The downward spray channels of a sprinkler nozzle, installed with the bulb upward, reduce the time the flow reaches the source of fire and allows the flow of substance to dissipate less, concentrating all its droplets down to the source of fire.

The sprayer includes a hollow body equipped with a nut with a filter and configured to be connected to a pipeline in its lower part, for example, using a coupling.

The housing contains a thermoflask. To do this, a rod is inserted into the housing, holding the thermoflask, which partially fits into the nut with the filter. In this case, the rod is installed so that it blocks the inlet channel for supplying the fire extinguishing agent to the body cavity from the pipeline. The upper end of the thermoflask is fixed in a hollow screw, and the lower end is fixed in a rod.

Spray channels directed downward are formed in the body. On one side, the channels communicate with the internal cavity of the housing, and on the other side they have an exit to the outside. By downward direction we mean that the smallest angle between the axis of each spray channel and the vertical axis of the nozzle is less than 90°

In this case, there are seals between the body and the nut, and between the nut and the rod.

The body and other elements of the sprayer can be made of metal or polymer, depending on the specified operating conditions of the fire extinguishing system.

The sprinkler is constantly under standby pressure, and when activated it is under operating pressure. After the thermal lock (thermal flask) of the sprinkler is activated and the opening for water supply is opened, a flow of fire extinguishing agent is supplied through the spray channels to extinguish the fire.
