Abstract
The utility model provides a drainage device that leaks of valve drenches, fire -fighting water pipe is connected through the first valve of normally opening to the water inlet of the valve that drenches with rain, a U -shaped steel pipe is connected to the delivery port of the valve that drenches with rain, U -shaped steel pipe opening up, the rear end of U -shaped steel pipe is connected to by protective apparatus through the first valve of normally opening, the bottom of U -shaped steel pipe connects the drainage tube, is equipped with the second on the drainage tube and normally opens valve and electric valve. The utility model discloses drench the valve and by protective apparatus between set up the U -shaped steel pipe, the U -shaped steel pipe has an unhurried current function because it itself has the potential energy difference, U -shaped steel pipe bottom set up can the drainage the drainage tube, can be fast with drenching the valve because of the sealed production carrying -off that leaks in that damages, leak in avoiding and cause the damage to automatic water spray fire extinguishing systems's protection.
Description
Technical field
The utility model relates to the application of drench valve.
Background technique
Drench valve is widely used in automatic water atomization fire-extinguishing system, and usual drench valve because bad seals or aging and leakage phenomenon water in occurs, inside can leak and may damage the object of protection of water spray fire extinguish system.The generator driven water atomization fire-extinguishing system in such as power station, when not having breaking out of fire, if drench valve leaks in occurring, then can cause the damage of generator component.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of drainage system that leaks of drench valve, can prevent from leaking in drench valve flowing into the measure of protected equipment, avoids the damage of leaking in drench valve to protected equipment.
The technological scheme that the utility model technical solution problem adopts is: a kind of drainage system that leaks of drench valve; comprise drench valve; described drench valve horizontal arrangement; the water intake of described drench valve connects fire-prevention pipe by the first normally open valve door; the water outlet of described drench valve connects a U-shaped steel pipe; described U-shaped steel pipe is opening up; the rear end of described U-shaped steel pipe is connected to protected equipment by the first normally open valve door; the bottom of described U-shaped steel pipe connects drainage tube, and described drainage tube is provided with the second normally open valve door and electric valve.
While employing technique scheme, the utility model can also adopt or combine and adopt following further technological scheme:
Described drench valve and electric valve are connected to Fire alarm control unit.
The outlet of described drainage tube passes to land drain.
The beneficial effects of the utility model are: the utility model arranges U-shaped steel pipe between drench valve and protected equipment; U-shaped steel pipe has unhurried current function because itself has potential energy difference; arranging bottom U-shaped steel pipe can the drainage tube of draining; can fast by drench valve because of bad seals produce in leak carrying-off, leak in avoiding and damage caused to the object of protection of automatic water atomization fire-extinguishing system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to accompanying drawing.
The drainage system that leaks of the present utility model comprises drench valve 3, drench valve 3 horizontal arrangement, its water intake and water outlet are on same level line, the water intake of drench valve 3 connects fire-prevention pipe 1 by a first normally open valve door 2, the water outlet of drench valve 3 connects a U-shaped steel pipe 4, the U-shaped of U-shaped steel pipe 4 is opening up, can pocket water bottom it, the rear end of U-shaped steel pipe 4 is connected to protected equipment by a first normally open valve door 2, the bottom of U-shaped steel pipe 4 connects drainage tube 5, drainage tube 5 is provided with electric valve 6 and the second normally open valve door 7, drainage tube after second normally open valve door 7 passes to land drain.
In order to realize automatic control, drench valve 3 and electric valve 6 can be connected to Fire alarm control unit.
Drainage method of the present utility model is as follows:
A, without fire time, when drench valve 3 because of bad seals occur in leakage after, inside leak because Action of Gravity Field is pooled to bottom U-shaped steel pipe 4, after drainage tube 5, drain into land drain.
When b, breaking out of fire, drench valve 3 is opened at once after receiving the signal of fire alarm system; Meanwhile, normally closed electric valve 6 is closed at once after receiving fire signal, prevents fire water from shunting from drainage tube 5.Drench valve 3 and electric valve 6 also can Non-follow control.
Claims (3)
