Abstract
The invention relates to a deluge valve with memory device. The deluge valve comprises a valve body, a valve plate, a control chamber, and a reposition chamber, wherein the control chamber is connected with a pressure water control pipeline; and a bistable-state solenoid valve is disposed in the pressure water control pipeline. The opening and closing of the deluge valve is respectively controlled by two independent electrical signals. When the system needs to open the deluge valve, the system transmits opening electrical signal to open the deluge; and when the system needs to close the deluge valve, the system transmits closing electrical signal to close the deluge. Thus, the deluge is only opened until the opening electrical signal is transmitted; and the deluge is only closed until the closing electrical signal is transmitted. Therefore, the deluge of fire extinguishing system can be reliably and accurately operated to prevent the deluge being automatically and erroneously closed during water spraying process.
Description
Technical field
The present invention relates to a kind of drench valve that has memory, adopt two independent different electrical signals during for the opening and closing of drench valve respectively.When drench valve need be opened by system, system sends opened electrical signal, opens drench valve; When system need close drench valve, system sent and closes electrical signal, closes drench valve.
Background technique
In the prior art, drench valve is one of core parts of a kind of open type automatic sprinkling system, and the difference of the reset mode of opening according to drench valve can be divided into the formula of automatically reseting and hand reset formula.Preceding a kind of mode: after drench valve was accepted the automatically controlled signal unlatching, as long as automatically controlled signal disappears, drench valve will be closed automatically.The second way: drench valve wants to close drench valve after accepting the automatically controlled signal unlatching, needs the fire personnel to reach the spot, and implements manual-lock.The drench valve of this dual mode all exists serious problems, the problem that preceding a kind of mode exists: when fire takes place, require these drench valves to be held open state, in case the suppression system dead electricity, the phenomenon that these drench valves will occur closing is automatically carried out thereby have a strong impact on fire-fighting work; The problem that the second way exists: in the fire extinguishing procedure, when some drench valve need be closed, the fire personnel can't reach the spot and implement to close, and will have a strong impact on the follow-up fire extinguishing effect of fire, therefore, needed to propose a kind of drench valve that has memory.
Summary of the invention
The objective of the invention is to propose a kind of drench valve that has memory, in the press water controlling plumbing fixtures of this drench valve bistable electromagnetic valve is housed, this solenoid valve has memory characteristic, after the controlled unlatching of drench valve, can not close automatically, when drench valve is controlled close after, can not open automatically, can improve the reliability of whole suppression system effectively.
The objective of the invention is to realize: a kind of drench valve that has memory by following technical proposals, described drench valve has a valve body, have valve plate in this valve body, control chamber, chamber resets, its main points are: connect the press water controlling plumbing fixtures on the described control chamber, in this press water controlling plumbing fixtures bistable electromagnetic valve is housed.The opening and closing of drench valve of the present invention are controlled by different electrical signal respectively, after the controlled unlatching of drench valve, can not close automatically, when drench valve is controlled close after, can not open automatically.
Compared with the prior art the present invention has reliable operation, and control is sensitive, prevents the advantage that drench valve is closed automatically in the water spray process.
