Abstract
The utility model provides a preaction valve installation for fire control, it includes preact warning valves (3), piping manifold (1), secret water supply pipe (2) and controller, piping manifold (1) is connected with secret water supply pipe (2), and preact warning valves (3) lies in between piping manifold (1) and secret water supply pipe (2), preact warning valves (3) and secret water supply pipe (2) between through reserving water inlet channel (4) intercommunication, be equipped with solenoid valve (5) on reserving water inlet channel (4), solenoid valve (5) all are connected with the controller is electric with drench with rain alarm valve (3), still be equipped with water level inductor (6) in the preact warning valves (3), water level inductor (6) are connected with the controller electricity.
Description
Technical field
The utility model relates to a kind of preaction valve installation for fire-fighting
Background technology
Preaction valve installation is used for fire-fighting early warning system, and it comprises preact alarm valve group, transmission system, grid, automatic sprinkler, water source control valve etc.Low-pressure air is filled with, for the sealing situation of detection system grid in the pipeline of preaction valve installation.When protection zone outlet fire alarm, detection system works, open the electric-powered air release valve for being vented in preact drench valve and system, now system starts to wash by water and is vented, if the intensity of a fire continues development, automatic sprinkler opens water spray, put out a fire, preaction valve installation can prevent deluge system from causing the defect of spray by mistake because of detection error, if arbitrary shower nozzle is unexpected damaged in system, then can from this shower nozzle ejection gas, air pressure in system is caused to decline rapidly, and send alarm signal, remind operator on duty that exception occurs, but preact drench valve does not have action, therefore system can not be sprayed water.
Preact alarm valve group comprises deluge alarm valve, control device, air pressure holdout device, air feeder etc., deluge alarm valve is the major control valve of system, grid and water system are separated by it, when installing preaction valve installation, deluge alarm valve is in closed condition, one end discharge that usual meeting is positioned at deluge alarm valve at grid has the reserved water of certain depth for ensureing the gas tightness of deluge alarm valve, existing preaction valve installation bails by manually arranging to the discharge of reserved water, its hermetic seal cannot be checked when discharging reserved water, and manual emission reserved water is cumbersome.
Utility model content
Technical problem to be solved in the utility model: the preaction valve installation for fire-fighting that a kind of automation is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of preaction valve installation for fire-fighting, it comprises preact alarm valve group, grid, groundwater supply pipeline and controller, grid is connected with groundwater supply pipeline, preact alarm valve group is between grid and groundwater supply pipeline, being communicated with by reserved water inlet channel with between groundwater supply pipeline of described preact alarm valve group, reserved water inlet channel is provided with magnetic valve, and magnetic valve and deluge alarm valve are all electrically connected with controller; Also be provided with water level sensor in preact alarm valve group, water level sensor is electrically connected with controller; Grid is also provided with air gauge.
As preferably, it also comprises alarm, and alarm is electrically connected with controller.
Adopt said structure, the utility model is advantageously: open or close reserved water inlet channel by controller Controlling solenoid valve, water in water supply line is discharged in preact alarm valve group, simultaneously can the air pressure of inside, Real-Time Monitoring official website, the monitoring of gas tightness, thus ensure good gas tightness; By water level sensor and barometricly to cooperatively interact, when reserved water is discharged into certain depth, water level sensor by signal feedback to controller, controller shut electromagnetic valve, stop the discharge of reserved water, automaticity is high; Alarm, for pointing out staff, plays alarm function.
Accompanying drawing explanation
Fig. 1 is the partial structurtes schematic diagram of a kind of preaction valve installation for fire-fighting of the utility model.
As shown in the figure: 1-grid, 2-groundwater supply pipeline, 3-preact alarm valve group, 4-reserved water inlet channel, 5-magnetic valve, 6-water level sensor.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
In the utility model describes, it will be appreciated that, term " on ", D score, " interior ", the indicating position such as " outward " or position relationship be based on the position relationship described in accompanying drawing, be only the present invention for convenience of description or simplified characterization, instead of indicate the specific orientation that must have.
As shown in Figure 1, a kind of preaction valve installation for fire-fighting, it comprises preact alarm valve group 3, grid 1, groundwater supply pipeline 2 and controller, grid 1 is connected with groundwater supply pipeline 2, preact alarm valve group 3 is between grid 1 and groundwater supply pipeline 2, it is characterized in that: being communicated with by reserved water inlet channel 4 with between groundwater supply pipeline 2 of described preact alarm valve group 3, reserved water inlet channel 4 is provided with magnetic valve 5, and magnetic valve 5 and deluge alarm valve 3 are all electrically connected with controller; Also be provided with water level sensor 6 in preact alarm valve group 3, water level sensor 6 is electrically connected with controller; Grid 1 is also provided with air gauge.
It also comprises alarm, and alarm is electrically connected with controller.
Open or close reserved water inlet channel 4 by controller Controlling solenoid valve, the water in water supply line 2 be discharged in preact alarm valve group 3, simultaneously can the air pressure of inside, Real-Time Monitoring official website 1, the monitoring of gas tightness, thus ensure good gas tightness; Cooperatively interacted with barometric by water level sensor 6, when reserved water is discharged into certain depth, water level sensor 6 by signal feedback to controller, controller shut electromagnetic valve, stop the discharge of reserved water, automaticity is high; Alarm, for pointing out staff, plays alarm function.
Be described the utility model and embodiment thereof above, this description does not have restricted, and shown in accompanying drawing is also one of embodiment of the present utility model, and actual structure is not limited thereto.If generally speaking those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
