The invention relates to a valve for piping systems containing fire fighting supply for fire extinguishing fluid under high pressure, the disposition of the fire-extinguishing fluid, located between the inlet and outlet shut-off means and operate the shut-off means the Executive the means to shut-off switch means in open and closed positions, and at rest, the locking means are in the closed position, and in case of fire the Executive means switch locking means from the closed position to the open position so that the fire extinguishing fluid flows from the inlet to the outlet.

The piping of the sprinkler systems in the state of rest, as a rule, already filled with fire extinguishing fluid. These so-called wet systems differ in that the fire-extinguishing liquid is constantly in the pipeline and in the event of a fire, it quickly gets to the sprinklers.

In order to avoid leak of fire extinguishing fluid in the rest of the piping system before the sprinklers or offsets in piping systems is the shut-off valve. This valve prevents the ingress of fire extinguishing fluid directly to the sprinklers. In the event of a fire, the valve is opened by remote-controlled servo motors, so that pajaritos is based on the fluid flows from the sprinklers.

For leak detection fire extinguishing fluid at rest is maintained under low pressure standby. This pressure is typically about 20 bar. In case of fire, fluid pressure greatly increases, so that, for example, of sprinklers can be atomized fine mist.

To ensure the functioning of the valve even in the event of a fire, they should be regularly serviced. For maintenance of valves they are activated. Thus, for example, at least 90 turn ball valves. Due to this detected plaque trapped foreign body, swollen and damaged gaskets, corrosion and other causes clogging of the valves. Jamming or other malfunctions of the valves must be installed in a timely manner, so that in the event of a fire to ensure their reliable operation.

Traditional maintenance valves regularly open. To do this, the technician uses a shut-off valve with a lateral release. Manually opens the check valve, and fire-extinguishing fluid flows through a lateral release. Then the valves are again manually to its initial position. The service leads to the fact that the fire-extinguishing fluid regularly refilled in the pipeline, and the pressure of rest to re - adjust. Escaping the fire-extinguishing liquid for the service may also have negative consequences, if protected areas are stored susceptible to moisture objects.

Due to these shortcomings the basis of the invention was based on the task of creating a valve for pipe sprinkler systems, jamming which could be detected without escaping the fire-extinguishing liquid from the pipeline.

In particular, it is possible to maintain the locking means through remote maintenance, in which the control of spatially separated from the valves. First of all, in the tunnels of several kilometres in length, it is advisable Central management service valves, so that you do not want the technician manually controlled all locking tools separately.

Derived previously from the prior art problem is solved, according to the invention, due to the fact that the locking means is arranged to switch in maintenance mode from its closed position with actuating means so that in maintenance mode fire-extinguishing fluid flows from the inlet to the outlet.

It was found that jamming the locking means can be detected by switching the locking means with the aid of actuating means during maintenance. In order to avoid leak of fire extinguishing fluid in maintenance mode during the enforcement process locking means done is by thus they are in maintenance mode exclude communication between the inlet and outlet. Due to the application of starting torque when switching the shut-off means in maintenance mode is destroyed minor tarnish and corrosion. After that, the valves are again fully operational.

Particularly preferably, the locking means formed by the ball valve and the ball valve is between the open and closed position of service. The ball valve can be performed, for example, in the form of 3-way 2-way ball valve. In this case, the hole of the valve body may be closed. The 3-way 2-way ball valve with a closed hole the ball can be rotated Executive means approximately 180no penetration fire extinguishing fluid from the inlet to the outlet.

The 3-way 2-way ball valve casing may be made so that coupled with the input valve output groove in the case of rotating the ball 90 closed. Ball ball valve can have any form of grooves, which allow you to rotate the ball valve in the provision of service between the open and closed positions without penetration fire extinguishing fluid from the inlet to the outlet.

Jamming of the ball of a ball valve is easy to detect when in maintenance mode, the ball valve can be rotated and the additional means, at least 50, preferably at least 90. Turn ball valve, at least 50 allows to reliably detect jamming. Light touch can be destroyed, and the operability of the ball valve is preserved.

The form of grooves in the ball of a ball valve can be performed preferably in such a way that the angle between the inlet and outlet openings ball valve is 5-175, mostly 90. The location of the holes in the valve body and the bores in the ball of a ball valve may be such that it allows rotation of the ball valve of at least 50 without escaping the fire-extinguishing liquid.

Also especially preferably, the locking means include the protective membrane and the stopcock. Protective membrane made with the possibility of destruction only when the pressure of peace. This occurs, for example, in case of fire. The shut-off valve prevents the fire extinguishing liquid from the sprinklers in case of accidental destruction of the protective membrane. Protective membrane forms together with shutoff valve double protection against leaks.

Also particularly preferred if the shutoff valve is a ball valve or solenoid valve.

Especially preferred if the overload diaphragm is located between what Odom and shutoff valve so the shut-off valve at rest dry. In this case, the protective membrane is located so that it reliably seals the stopcock at rest from the supply. In this case, the stop valve can be opened without escaping the fire-extinguishing liquid. The fire-extinguishing liquid is retained protective membrane in the cart. Only in the event of a fire protective membrane is destroyed, and actuating means turn the stopcock in the open position, so that it is possible to reliably extinguish the fire.

Likewise particularly preferred if the overload diaphragm is located between the shutoff valve and drain so that the shut-off valve at rest filled with fire extinguishing fluid. In this case, the shut-off valve prevents accidental destruction of bursting due to excessive pressure of calm. In the event of a fire protective membrane is destroyed after opening the shut-off valve as the fluid has pressure. In the case of maintaining a shut-off valve can be opened by the Executive means. Overload diaphragm withstands peace without destruction. Fire-extinguishing fluid flows from the sprinklers, delayed because of the safety membrane.

Preferably also, if the Executive environments, the Batwa are driven pneumatically or electrically. Such Executive means can be, for example, electric motors.

The position of the actuating means can be set by sensors. These sensors can be, for example, the end position switches and circuit breakers service position. These switches control the control means. The sensors can be controlled, in addition, the operational range of the actuating means. The sensors provide remote maintenance actuating means by means of remote control electric motors and control functions of the motor or the position of the actuating means.

Other signs are given in the dependent clauses.

Below the invention is explained in more detail using depicting examples of its implementation of the drawing, which are:

- figure 1: schematically fire-extinguishing system;

- figure 2: a variant of the system of figure 1;

- figure 3: valve with safety diaphragm in the first exemplary embodiment;

- figure 4: valve with safety diaphragm in the second exemplary embodiment;

- figa: valve with ball valve in the closed position;

- fig.5b: valve with ball valve in position of service;

- figs: valve with ball valve in the open position.

The device 1 for fire extinguishing contains feeding devices is 2, includes tank and high pressure pump (not shown). Alternatively, the power supply device 2 can be equipped with one or more receivers, in which the pressure is kept the fire-extinguishing liquid. Fire extinguishing liquid can be stored under ambient pressure, and only when active, it affects the pressure of one or more receivers. The feeding device 2 is controlled by the control device 3, which receives the signal about the fire from the fire sensor 4.

In the example in figure 1 to a power supply device 2 through the main supply line 6 and a branches off from the main supply line 6 of the supply lines 7, 8, 9 attached sprinklers 10, 11, 12.

In the example in figure 2 the first group of 13 from three sprinklers 14 through the coupler 15 is attached to the exhaust from the main supply line 16 of the supply line 17. In addition, a separate sprinkler 18 is attached directly to the power line 19, the exhaust from the main supply line 16. Three sprinkler 21 of the third group 20 is connected through the intermediate line 22 and the coupler 23 to the third supply line 24 extending from the main supply line 16.

Sprinklers 10, 11, 12, 14, 18, 21 can hold open insert, through which is made in the appropriate sprinkler channels are connected with the inlet of the sprinkler. When applying after otousama fluid under high pressure up to 300 bar inserts create a fine mist fire extinguishing.

Figure 3 in the first preferred example shown, the valve 50. Via a feed line 7 fire extinguishing fluid is delivered 32 valve 50 calm under pressure of about 20 bar. The valve 50 includes the protective membrane 30, the inlet 32 and the outlet 34, the stop valve 36, the Executive means 38 and the sensor 40.

The fire-extinguishing liquid is retained protective membrane 30 in the supply line 7. It seals the valve 50, in particular the shut-off valve 36, from the fire-extinguishing liquid. At rest stop cock 36 dry. For maintenance you can use the actuating means 38 to change the position of the shut-off valve 36. For example, the shut-off valve 36 can be formed by an electromagnetic valve, which has open and closed positions. Executive means 38 can have a remote control.

With the help of the actuating means 38 can perform reciprocal switching between open and closed positions. The position of the actuating means 38 is determined by the sensors 40. By means of the auxiliary drive (not shown) Executive means 38 can switch in case of service from the displayed position above the sensor 40A to a position above the sensor 40b. Sensor 40b determines the switch actuating means 38 and notifies the control device, so that the switch p is harivamsa. Then the Executive means 38 by means of auxiliary drive again switched back into the shown position. Achieving this position is determined by the sensor 40b. By switching when the service determines the tarnish and corrosion in the locking means 36.

In the event of a fire increases the fluid pressure, and this leads to the fact that the protective membrane 30 is destroyed. Additionally using the actuating means 38 shutoff valve 36 is rotated to the open position, so that the fire extinguishing fluid can flow from the inlet 32 to the outlet 34 and the fire can be extinguished.

Figure 4 shows another variant of the valve 50. When this protective membrane 30 is located behind the shutoff valve 36. At rest stop cock 36 filled with fire extinguishing fluid. Switch actuating means 38 from the closed position to the open position causes the fact that the fire-extinguishing liquid in the outlet 34 abuts against the protective membrane 30. Protective membrane 30 seals the outlet 34 from the rest of the pipeline, so that the fire extinguishing fluid is unable to flow.

In case of fire the Executive means 38 is switched so that the shut-off valve 36 is in the open position. Fire extinguishing liquid rests with the increased pressure in the protective membrane 30, in which R is slushaetsa and fire.

On figa schematically shows the ball valve 44. It contains a ball 46 with the flow channel 48. Ball 46 is rotated Executive means (not shown). The position of the ball 46 is determined by sensors (not shown). In position on figa ball 46 is in the closed position. A flow channel 48 of the ball 46 is made so that it has not communicated with either the inlet 32 or outlet 34.

In case of maintenance of ball 46 is rotated into position on fig.5b. Thus the supply 32 is in communication with the flow channel 48. Fire extinguishing fluid may not, however, flow into the outlet 34, as between inlet 32 and outlet 34 no direct connection. The ball valve 44 seals the inlet 32 from the outlet 34. Due to the rotation of the ball 46 ball valve 44 to 90 can be set, not stuck if the ball 46.

The regular rotation of the ball 46 from figa in position on fig.5b you can set the jamming of the ball 46. In the case of a jammed valve 50 can be replaced.

The regular control ball valve ball 44 46 can be in the event of a fire easily rotated into position on figs. In this case, the flow-through channel 48 provides a direct connection between the inlet 32 and outlet 34. Fire extinguishing fluid can flow through the flow passage 48 in the outlet 34 and effectively extinguish the fire.
