Definitions
- the claimed technical solution generally relates to fire-fighting equipment used as part of automatic fire extinguishing systems and, in particular, to a sprinkler for supplying fire extinguishing liquid (in particular water) in the form of a finely sprayed stream.
- fire extinguishing liquid in particular water
- the sprinkler of the fire extinguishing system usually consists of a body, a shut-off valve, a socket for spraying liquid flowing from the outlet of the sprinkler, a temperature-sensitive element that holds the shut-off valve of the sprinkler and is activated when the set temperature is reached.
- thermoflasks As a temperature-sensitive element of a thermal lock, discontinuous elements are currently used - glass thermoflasks.
- the principle of operation of a sprinkler sprinkler is as follows. When the temperature in the thermal lock zone exceeds its nominal response temperature, the thermal bulb is destroyed, the shut-off valve falls out of the sprinkler housing socket, and the water flow, hitting the sprinkler socket, is distributed over the protected area.
- a sprinkler of a fire extinguishing system is known from the prior art (RU 2652587, publ. 24.05.2017).
- the well-known sprinkler of the fire extinguishing system contains a housing with an outlet closed by a shut-off valve, a temperature-sensitive collapsing element and a trigger control device.
- the actuation control device is made in the form of a conductive coating deposited on the surface of a thermally sensitive collapsing element, and the coating has leads for inclusion in the circuit of the sprinkler condition control unit.
- a sprinkler of a fire extinguishing system is also known from the prior art (RU 155310, publ. 27.09.2015).
- a device for forced start-up of a sprinkler sprinkler with a thermally collapsing glass bulb, with an electrically controlled pyrotechnic drive installed near it in which a flexible plastic bracket is installed, made in the form of a flexible figured strip, covering the sprinkler arms and fixed on them with the help of internal strip stops and with the help of a snap lock made at the ends of the strip, while on the wall of the strips there is a socket for a pyrotechnic drive, which is installed and fixed in the socket with a retaining ring, and thinnings are made in the places of bending of the strip.
- the actuating mechanism for the signal-starting fire extinguishing device consists of a sprinkler sprinkler with a fragile (brittle) spacer element, which is placed between the valve and the adjusting screw, with a pyrotechnic drive with electric start installed near it.
- a fragile (brittle) spacer element in the form of a glass rod with rounded support ends, approximately spherical in shape.
- the actuator for a fire extinguishing signal trigger (RU 2614206 C1, publ. 03/23/2017).
- the actuator consists of a sprinkler with a fragile (brittle) locking element placed between the valve and the adjusting screw.
- the locking element is made in the form of a fragile electrical insulator of a cylindrical shape with rounded support ends
- the temperature-sensitive element is made of a wire with a shape "memory" effect in the form of a ring with rigidly fixed ends of the wire, while the ring covers the locking element on one side, and on the other side it covers one from the side parts of the sprinkler arch, and the ring is installed from the locking element to the arch along the shortest path at normal operating temperature in a forcibly stretched state, while the total length of the forcibly stretched ring exceeds the total length of the ring with the initially given shape by (7 8)%, in addition , at the ring, at the point of its connection with the locking element, a connection is made with the first electrical outlet and a second electrical outlet is made, located at the point of contact of the ring with the shackle, the opposite ends of both electrical outlets are connected to the power supply through the control panel by means of an electrical connector installed on the sprinkler body, with the possibility of electrically controlled forced start

- the disadvantage of the technical solutions known from the prior art is the external influence on the thermosensitive flask. Any intervention or application of additional elements to the surface of the flask violates the technical characteristics of the flask, and accordingly affects the reliability of the operation of the thermosensitive flask. In the claimed invention, the technical characteristics of the flask are not violated, since in the claimed technical solution no changes are made to the design of the flask, the flask is used in the factory version, and, accordingly, the reliability of operation of the thermosensitive bulb remains at a consistently high level.
- the electrical contacts of the forced operation of the bulb are open to moisture access and, accordingly, oxidize over time under the action of humidity, which adversely affects the reliability of the mechanism for the forced operation of the fire extinguishing sprinkler.
- the technical problem to be solved by the proposed sprinkler of the fire extinguishing system is to provide the possibility of remote control, forced start and control of the state of the sprinkler of the fire extinguishing system.

- thermosensitive collapsing element is made in the form of a glass thermosensitive flask.
- thermosensitive flask is filled with a liquid that boils at the response temperature.
- Figure 1 sprinkler with controlled start.
- the sprinkler of the fire extinguishing system consists of a cylindrical body (12) with an internal working chamber.
- the sprinkler of the fire extinguishing system is equipped with a thermal lock of automatic operation.
- the thermal lock is made in the form of a spring-loaded valve, made, for example, in the form of a spool (11) and made with the possibility of translational movement inside the body of the fire extinguishing sprinkler, and a glass thermosensitive flask (10).
- the valve is located in the inner part of the sprinkler body (12), while the valve in the duty mode closes the channel for supplying fire extinguishing liquid to the sprinkler outlet nozzles.

- the claimed sprinkler of the fire extinguishing system in addition to the normal mode of operation, is made with the possibility of remote forced operation of the temperature-sensitive element in case of early detection of a fire.
- the claimed design of the mechanism for forced actuation of the sprinkler of the system excludes external influence on the heat-sensitive flask (10).
- the thermosensitive flask (10) bursts, thereby opening the nozzle. Any intervention or application of additional elements to the surface of the bulb violates the technical characteristics of the bulb (10), and accordingly affects the reliability of the operation of the thermosensitive bulb.
