General information

Trunk RSK-50 designed to extinguish fires with a compact or sprayed jet of water with a variable spray angle. RSK-50 barrels are equipped with mobile fire extinguishing equipment, and internal fire hydrants can also be equipped.

Trunks RSK-50, along with structurally similar trunks RSP-50, until recently, were one of the most common types of fire nozzles in the Russian Federation 50-00-00.PS, RSK-50-00-00.PS.

Design features

The trunk consists of a body 1 , connecting head 2 overlapping device with handle 3 and nozzle 4 .

The design of the barrel allows the formation of a compact or sprayed jet at the exit, thereby increasing the efficiency of extinguishing fires and more efficiently using the water supply.

The position of the handle of the shutoff device for shutting off, forming a compact or atomized water jet:

  • I position - the jet is blocked;
  • II position - compact jet;
  • III position - spray jet. The barrel of the RSK - 50 is additionally equipped with a device that allows you to change the angle of the spray jet, depending on the position of the spray nut 6 ;
  • IV position - the minimum angle of the torch;
  • V position - the maximum angle of the torch.

Specifying Security Measures

It is forbidden to use trunks near open power lines located within the radius of action of a continuous jet.

It is forbidden to wear the shoulder strap of the barrel connected to the hose line when lifting and working at height. By the time the water is started, the barrel must be securely kept working.

Barrel preparation for work

In preparation for work, the barrel should be securely connected to the hose line. Set the barrel handle to the position necessary for the formation of a certain type of jet and direct it to the fire. Signal readiness for work.

VNIIPO of the Ministry of Internal Affairs of Russia has developed manual fire nozzles RSP-50, RSK-50, RSP-70, RSKZ-70, devoid of these shortcomings.

They form continuous and atomized jets with a variable spray jet angle (RSK-50) and a water protective curtain (RSKZ-70), have a ball-type blocking device.

Designed for a working pressure of 0.4-0.6 MPa, they provide:

water consumption with continuous jet:

  • 2.7 l/s (RSP-50, RSK-50),
  • 7.4 l/s (RSP-70, RSKZ-70),

spray water consumption:

  • 2.0 l/s (RSP-50, RSK-50),
  • 7.0 l/s (RSP-70, RSKZ-70) and protective curtain 2.3 l/s.

Sometimes, when extinguishing a fire, stationary equipment cannot cope with the tasks that need to be solved as quickly as possible. This is largely due to the main disadvantage of such systems - the complete lack of mobility. That is why manual fire nozzles are the actual fire equipment that is on the market today.

In this article, we will consider the most popular models of manual fire nozzles, their functional features and principles of operation.

Device

The structural component of the universal barrels for manual use makes it possible to use both a continuous flow of fire extinguishing material and a sprayed one.

The RSK-50 manual barrel includes such elements as:

  • frame;
  • stopcock;
  • nozzle on the barrel;
  • connecting (integrated) head.

Structural elements of the RSK-50 barrel

The handle of a plug faucet is the main tool that controls the jet that is given out under pressure. By changing the position of the handle relative to the barrel itself, you can change the type of jet coming out of the barrel hole. The main types of water or foam mixture at the outlet:

  • solid stream;
  • spray stream;
  • protective curtain.

Depending on the case, it is possible to change the type of fire extinguishing material supplied without violating the functionality of the entire device.

The plug faucet handles on the other two models mentioned above have exactly the same functions.

When the handle 4 of the plug valve 3 is positioned along the axis of the body 5, the liquid flow passes through the central hole and then exits the nozzle 12 in the form of a compact jet. When the handle is turned by 90 0, the central hole is blocked and the liquid flow from the cavity 8 of the hollow plug of the tap through the holes 7 and 10 enters channels 1, 2 and 9. Through the tangential channels 11, the liquid enters the central atomizer and leaves it in a swirling flow, which under by the action of centrifugal forces, when exiting the nozzle, it is sprayed, forming a torch with an opening angle of 60 0 . A similar principle of operation is incorporated in the design of universal trunks RSP-50 And RSP-70. Trunk RSKZ-70 allows, in addition, to additionally form a protective water curtain.

Maximum blast distance

continuous jet:

  • 30 m (RSP-50, RSK-50),
  • 32 m (RSP-70, RSKZ-70);

spray jet:

  • 11 m (RSP-50, RSK-50),
  • 15 m (RSP-70, RSKZ-70);

effective spray range:

  • 5 m (RSP-50, RSK-50)
  • 10 m (RSP-70, RSKZ-70), the average irrigation intensity is 0.14 and 0.2 l / m 2, respectively.

Barrel weight: 1.5 kg (RSP-50), 1.9 kg (RSK-50, RSP-70) and 2.4 kg (RSKZ-70).

Fire tests of barrels under conditions close to those of a real fire were carried out in Perm and Samara at special test sites.

Extinguishing with sprayed water jets of diesel fuel, flammable combustible liquids with a flash point below 0 degrees, as well as a trap product, which is an oil recovery with a specific gravity of 0.8 t / m 3 and a flash point of +28 degrees, showed a higher efficiency of new manual fire hoses compared to existing ones.

The proposed trunks are recommended for use in the configuration of mobile fire equipment, as well as (trunks RSP-50, RSP-70) internal fire hydrants in residential, public, administrative, industrial buildings and structures.

To complete mobile fire equipment and equipped with hoses d 38 mm, a manual fire nozzle RSP-38 has also been developed, which has the following main parameters:

  • working pressure - 0.4-0.6 MPa;

water consumption:

  • continuous jet - 1.8 l / s; sprayed - 1.5 l / s.

jet distance:

  • solid - 25 m; sprayed - 11 m.

To supply water to the fire, fire nozzles of various modifications are used. The simplest ones create a continuous compact jet, some models allow the jet to be sprayed, as well as create a water curtain to protect against heat flow. A special class is represented by barrels for creating air-mechanical foam from a foam concentrate solution. NPO RUSARSENAL offers fire hand guns from various manufacturers in a wide range - from the simplest to the professional ones.

Range

Trunks are manual RS-25, RS-50, RS-50P, RS-70 are the simplest devices for creating a continuous compact jet. They are used, as a rule, for a complete set of fire cabinets.

For stationary mounting on a fire hose, modifications RS-50.01, RS-50.01P, RS-70.01 and RS-70.01P are used. They are used to complete fire cabinets, in cases where extension of the hose line is not required.

Fire barrels RSK-50, SRK-50, RSP-50, RSP-70 have the function of blocking the flow of water with the possibility of creating a continuous or sprayed jet with a constant angle of the torch. Trunk RSKZ-70 allows you to form a protective water curtain that protects the shooter from the heat flow.

Trunks ORT-50 And ORT-50A are more modern and complex products, due to which they have extended functionality:

  • formation of a continuous or sprayed jet,
  • formation of low expansion foam (using a removable foam generator),
  • formation of a spectrum of various jets and their combinations,
  • high spray quality with a wide range of spray angles.
