Abstract
The utility model discloses a wet-type alarm valve with a constant-pressure function. The wet-type alarm valve comprises a valve body, a valve seat, a valve clack, a system pressure gauge, a water supply pressure gauge, a main water drainage valve, a test valve, a time delayer, a pressure switch and a hydraulic alarm bell, wherein the right side of the valve body is connected with the system pressure gauge and the water supply pressure gauge via a tube network respectively; the left side of the valve body is connected with the test valve via the tube network, and then is connected with the time delayer via the test valve; the upper end of the time delayer is connected with the pressure switch and the hydraulic alarm bell via the tube network; the valve clack is arranged in the valve body, and the distance from the valve clack to the bottom of the valve body is 1/3 of the height of the valve body; an automatic pressure flow adjustor is directly arranged on the tube network for connecting the system pressure gauge with the water supply pressure gauge; and an automatic filter device is arranged in the tube network for connecting the system pressure gauge with the water supply pressure gauge. The wet-type alarm valve provided by the utility model is convenient to remove slag, convenient to install and low in maintenance cost.
Description
Technical field
The utility model belongs to automatic sprinkler system, is specifically related to automatic sprinkler system a kind of wet alarm valve wherein.
Background technology
The operation principle of wet alarm valve is to rely on the reduction of pipe network system side hydraulic pressure or raise to open and close the warning flap.Under set condition, when pressure of supply water had fluctuation slightly, the effect of bypass balance pipe made warning flap hydraulic balance up and down, and pressure-bearing surface is greater than following pressure-bearing surface on the warning flap, and flap can not opened the generation false alarm.Under the alarm valve set condition, should be in normally open.If breaking out of fire; After in case pressure forms certain pressure reduction about the warning flap, alarm valve can move voluntarily flap is opened, in the annular that just has one water to flow into immediately just to reveal under flap opening is poor, the aperture from the alarm valve body wall (technical be called report to the police mouthful) outflow and enter the warning pipeline again; Flow to delayer again.After current were full of delayer, water flow pressure actuating pressure switch seal membrane was finished signal of telecommunication output by the microswitch in the upward pressure switch of push rod top.Enter with the current of spray regime and impact the alarm bell blade rotation with the water inlet by the alarm bell porch of another strand current constantly, make warning water system carry out audible alarm.In case stop discharging water or after stopping the shower nozzle sprinkling, the current of water supply side reenter fire_fighting pipe network by alarm valve, after treating alarm valve both sides (upper and lower cavity) hydraulic balance, the flap of alarm valve can be closed because of deadweight again, rubber washer below the flap covers the poor face of annular tightly, press water can't enter that annular is poor, and the warning pipeline does not have pressure flow, alarm valve is presented on again watch to answer duty.But traditional wet alarm valve is in the fire engineering of fire extinguishing system.
" a kind of wet alarm valve " CN201120350573.9 adopts and in the flap upper and lower surface moisturizing hole is set; though solved pressure balanced problem; but; in reality in long-time use; the pipe network of system can occur impurity such as iron filings usually and cause the gravity ball can not reach budgetary effect; cause outside the slow phenomenon of alarm valve time of fire alarming thereby at this time can form the certain pressure difference between water outlet and the intake antrum, even also following situation can occur: abnormal conditions such as long warning, gap warning.
The utility model content
At above-mentioned prior art, the purpose of this utility model is to provide a kind of residue-discharge convenience, easy for installation, wet alarm valve that maintenance cost is low.
Below in conjunction with accompanying drawing the utility model is further described, but never in any form the utility model is limited, any conversion or replacement based on the utility model training centre is done all belong to protection domain of the present utility model.
In order to solve the problems of the technologies described above, the wet alarm valve with constant voltage function of the present utility model comprises: valve body, valve seat, flap, system pressure table, pressure of supply water table, main water discharging valve, pet valve, delayer, pressure switch, warning water system; The valve body right side is by pipe network difference connected system Pressure gauge and pressure of supply water table, pass on left pipe network and connect pet valve, connect delayer again by pet valve, the delayer upper end connects pressure switch and warning water system by pipe network, valve inner 1/3rd location arrange flap, at the pipe network of connected system Pressure gauge and pressure of supply water table the pressure flow automatic regulator are set directly; In the pipe network of connected system Pressure gauge and pressure of supply water table automatic filtering unit is set.
As further improvement of the utility model, automatic filtering unit be in preposition filtration or the filter screen wherein one or both.
As further improvement of the utility model, automatic filtering unit is fore filter.
As further improvement of the utility model, automatic filtering unit is filter screen.
As further improvement of the utility model, automatic filtering unit is fore filter and screen pack complement filter.
