Abstract
The utility model provides a deluge alarm valve which can be automatically or manually controlled, and belongs to the field of fire extinguishment. The deluge alarm valve is shaped like a spindle, and the water supply flow of the deluge alarm valve reaches 14000L/min. The deluge alarm valve is composed of a valve body, a valve deck, a diaphragm, an insert, a flow guiding body, a spring, a bolt and a valve seat, wherein the valve deck, the diaphragm and the valve body are fastened through the bolt, the insert is arranged inside the diaphragm in a die casting mode, the valve seat is fixed inside the valve body in an embedding mode, the spring is installed between the valve deck and the diaphragm in a pre-compressed mode, and the flow guiding body is installed at the bottom of the diaphragm. At ordinary times, water flow at the water source side enters a diaphragm cavity through a connecting piece outside the valve, through the common action of water pressure of the diaphragm cavity and spring force, the diaphragm shifts downwards to abut against the valve seat, and the deluge alarm valve is closed and sealed. When the deluge alarm valve is opened, the pressure of the diaphragm cavity is relieved, and the diaphragm is opened for effluent of water under the pushing of the pressure of a water source. The deluge alarm valve solves the problems that the diaphragm of a conventional deluge alarm valve can bear low pressure and is prone to deformation and cracks, improves opening and closing operation flexibility of the diaphragm, and lowers water power friction, thereby having broad application prospects in the water spray and foam spray combined fire-extinguishing system.

Background technique
Current deluge alarm valve, barrier film does not have built-in pressure-bearing mold insert, and in the time of servo condition, barrier film pressurized produces the protruding stretching of drum, and the cracking that often meets accident, causes deluge alarm valve to open by mistake and opens water outlet accident, and the normal service life of barrier film is only 1 year; Conventional deluge alarm valve can not meet the large flow fire-fighting demand for metallurgy, 1100KV current conversion station, ten ton basins.
Summary of the invention
Lower in order to solve deluge alarm valve barrier film pressure-bearing, yielding, to ftracture problem, the utility model provides a kind of deluge alarm valve, its rated working pressure is 1.6MPa, nominal diameter 300mm, loss of head≤0.030MPa, water supply flow reaches 14000L/min, opening time <15s; The cylindric barrier film of the utility model design rubber mold pressing mold insert, the principle that adopts the lifting of hydraulic pressure control barrier film to open and close, has slowed down current zig zag eddy current, in water spray, foam spray combined medium extinguishing system, is with a wide range of applications.
The utility model is achieved through the following technical solutions:
Deluge alarm valve is made up of valve body, valve gap, barrier film, mold insert, valve seat, deflector, spring, bolt; Valve gap, barrier film and valve body are by bolton, and within mold insert is molded to barrier film, valve seat build-in is among valve body, and spring is loaded between valve gap and barrier film, and deflector is loaded on separator bottom.The principle that adopts the lifting of hydraulic pressure control barrier film to open and close, sealing is closed in the pressurization of diaphragm cavity water-filling, and diaphragm cavity sluices and opens water outlet.
The current of water source side by valve externally connected pipe, enter diaphragm cavity at ordinary times, and the acting in conjunction of hydraulic pressure and spring thrust by diaphragm cavity, makes barrier film prop up valve seat to bottom offset, closes sealing; When unlatching, venting diaphragm cavity pressure, barrier film is opened water outlet under the promotion of source pressure; When reset, stop diaphragm cavity pressure release, recover to press in diaphragm cavity water filling, the acting in conjunction of hydraulic pressure and spring thrust by diaphragm cavity, barrier film props up valve seat to bottom offset, closes sealing.Due to the principle that adopts the lifting of hydraulic pressure control barrier film to open and close, the utility model has been realized level, the vertically requirement of installing and using, and possesses and repeat the automatic cycle electric control function processed of opening, closing.
The beneficial effects of the utility model are: the cylindric barrier film of rubber mold pressing mold insert is set, has improved barrier film intensity, solved the hidden danger of diaphragm deflection, cracking, extended working life; Several uniform longitudinally guiding muscle have been designed in valve body chamber, guarantee under the precision of barrier film upper and lower displacement, have reduced the surface friction drag between valve body and barrier film external cylindrical surface, have improved and have opened and closed sensitivity; Barrier film below downstream stream is provided with deflector, has avoided current zig zag, has reduced flow resistance loss; The principle that adopts the lifting of hydraulic pressure control barrier film to open and close, the utility model has been realized level, the vertically requirement of installing and using, and possesses and repeat the automatic cycle electric control function processed of opening, closing.
