The device ventilation tower installation
The invention relates to defence technique and can be used in the battle tower installations. The invention consists in that the device ventilation tower installation, containing the fan, limit switch, valve box, valve and rod, and a roller lever, a lever pivotally connected with the rod, and at its outer end a roller rigidly mounted switch with spring. The other end of the spring connected to the valve box. Spring is installed with the ability to transfer it from one stable position to the other through an unstable position. From opposite sides of the switch in the plane of its swing on the valve box installed two electromagnet, in turn interacts with the switch and the target switch - can be used to communicate with the switch in one of the stable positions of the spring is electrically connected to the electromagnets and electric fan. The technical result of the invention is to increase the safety of the arrow. 1 Il.The present invention relates to defence technique and can be used in the battle tower installations.Known ventilate .Fan tower installation contains the fan, limit switch, valve box, valve stem and spring. Under the action of the spring the valve is constantly pressed against the end face of the valve chest, excluding the message podveshennogo space with the external environment. Before shooting the shooter to manually open the valve by a lever mounted on the valve box. To hold the valve in the open position the lever is fixed by the stopper. When the lever arm acts on the limit switch, mounted on the valve box, which closes the circuit of the electric fan and produces a suction of podveshennogo space of the powder gases generated during firing. After the shooting, the shooter removes the arm from the stopper and the valve under the action of the spring is closed. This lever releases the limit switch and the fan turns off. Removing the lever from the stopper can be made using a magnetic switch mounted on the valve box. But this happens only on the signal PRHR (unit of radiation and chemical reconnaissance).The disadvantage of this design is that the operations for opening and closing the valve are shot manually, which uhowie gases will accumulate in Padmasana room that reduces the safety of the operation of the arrow.The invention solves the problem of increasing the safety and convenience of the arrow due to the automatic control of the fan tower.To solve the problem in the fan tower installation, containing the fan, limit switch, valve box, valve rod, roller lever, cooperating with the valve stem, it is new that the lever with the valve stem is connected pivotally, as at the outer end of the roller is rigidly fixed to the switch. It is spring, the other end of which is fixed on the valve box. Moreover, the attachment point of the spring, when its unstable position and switch, are located on the same line with the axis of rotation of the switch. When turning the switch counterclockwise or clockwise, the spring means from one stable position to the other through an unstable position, carrying with it the power closure mechanism, respectively, using the lever producing the opening and closing of the valve. On the valve box installed limit switch with the possibility of contact with the switch. On the valve box from opposite sides of the switch secreet when opening fire and executes the transfer of the switch, which under the action of the spring lever opens and keeps the valve. When this switch communicates with the destination switch that turns the fan on and removes power from the solenoid. Another electromagnet is triggered when the ceasefire or signal PRHR and carries out the transfer switch, which under the action of the spring lever closes and keeps the valve. When this switch is out of contact with the end switch and the fan is switched off.The hinged connection of the lever with the valve stem, the application switch and springs with changing its position relative to the axis of swing of the switch and use as control elements switch 2 electromagnets provide automatic control of the fan tower without the participation of the arrow, which increases safety and convenience of the latter.The drawing schematically shows the fan tower installation in the working position.On the roof of the tower 1 fan installed in the tower installation, consisting of a fan 2, mounted on the valve box 3. In the guide 4 valve boxes installed valve 5 with the rod 6, which is hinged to ruet, for example, a tension spring 10, secured to the valve box. The spring 10 is set so that when you turn the switch 9 clockwise it is located to the left of the roller 8, and when turning the switch counterclockwise to the right of the platen 8. The lever 7 is in the lower, upper positions, respectively, providing the closing or opening of the valve. On the valve box fixed electromagnets 11 and 12, which in turn interact with the switch 9. Limit switch 13 is mounted for contact with the switch. When opening fire power to the electromagnet 11 and he, acting on the switch 9, rotates counterclockwise. Spring 10, moving to the right from the axis of swing, continues to affect the switch 9. This lever 7 raises the rod 6, opening the valve 5, and the switch is in contact with a limit switch 13, which includes the fan 2 and removes power from the electromagnet 11. The valve is held in open position by the spring 10, and the powder gases are removed outside the tower. When you stop shooting or 4 signal PRHR is power to the electromagnet uchtala, continues to rotate it. This lever 7 lowers the rod 6, closing the valve 5, and the switch 9 becomes in contact with a limit switch 13, which turns off the fan 2 and de-energizes the electromagnet 12. Spring 10 holds the valve in the closed position.If necessary, the shooter can manually open and close the valve by turning the switch.The source of information1.

SUBSTANCE: according to the proposed method, excess pressure in a fighting compartment is measured by means of an air overpressure metre. The latter represents a glass tube with two marks, which is connected to atmosphere, and with a ball arranged in the tube. When excess pressure of 35 mm of water column is reached, the air overpressure metre ball moves upwards along the tube to upper position, which gives evidence of available air overpressure. Excess air pressure acts on the piston and moves it. At the piston movement, an electric circuit is closed, and a signal from a lamp and through a register of a sound signalling device warns the crew of available air overpressure in the inhabited compartment.
EFFECT: increasing degree of informativity of a crew.
