Abstract
The utility model discloses a diaphragm type rain alarm valve with a water pressure type anti-reset controller, comprising a diaphragm rain main valve and a diaphragm rain main valve controlling valve set connected with a diaphragm water inlet controlling opening of the diaphragm rain main valve, wherein, the diaphragm water outlet controlling opening is connected with a water pressure type anti-reset controller through a pipeline valve. The rain alarm valve can not be closed even though the valve is closed due to the false operation of the diaphragm rain main valve controlling valve set.
Description
The utility model belongs to the fire main alarm valve, is specifically related to the diaphragm type alarm valve that drenches with rain.
The diaphragm type of the Xiao Shouing alarm valve that drenches with rain in the market mainly comprises the barrier film main valve that drenches with rain, with barrier film a barrier film that the barrier film water inlet control mouth of main valve the is connected main valve control valve group that drenches with rain that drenches with rain.When this alarm valve that drenches with rain uses, can occur because the misoperation of control valve group, cause barrier film to drench with rain problem that main valve closes, this series products is substandard product now.
The purpose of this utility model is to design a kind of diaphragm type with the anti-reset controller of hydraulic type alarm valve that drenches with rain.
The technical solution of the utility model is: based on the existing barrier film main valve that drenches with rain, mouthful connect the barrier film main valve control valve group that drenches with rain in barrier film water inlet control; Going out the water management mouth at barrier film is connected by the anti-reset controller of pipe valve and hydraulic type.
This valve connects anti-reset controller owing to go out the water management mouth at barrier film, and when barrier film drenches with rain main valve control valve group when misoperation occurring, anti-reset controller is opened the water that enters diaphragm cavity and flowed out, and guarantees that the barrier film main valve that drenches with rain do not close.

Embodiment:
Barrier film in the utility model main valve that drenches with rain is controlled direct diaphragm type diaphragm valve for existing waterpower, can be angie type, horizontal etc.Here we adopt as shown in Figure 1 the barrier film main valve that drenches with rain, and it comprises the valve gap 1.1 that valve body 1.4 is connected with valve body 1.4, establishes spring 1.2 and diaphragm assembly 1.3 in the valve gap 1.1.Offer barrier film water inlet control mouth 1.5 and barrier film on the valve gap 1.1 and go out water management mouth 1.6.Be provided with the piston 1.7 that is connected with diaphragm assembly 1.3 in the valve body 1.4, piston 1.7 lower ends connect black box 1.8, and black box 1.8 contacts with valve body current control mouth 1.9.
The anti-reset controller of hydraulic type as shown in Figure 2, comprise valve body 2.1, the pressure sensitive hole 2.2 that is provided with on the valve body, the valve gap 2.3 that is connected with valve body 2.1 is established spring 2.4 in the valve gap, regulating shaft 2.5, diaphragm 2.6, diaphragm is connected with piston 2.7, and piston rod 2.8 lower ends connect flap assembly 2.9, and flap assembly 2.9 can seal with the valve seat 2.10 that is located on the valve body 2.1.
The barrier film of the anti-reset controller of band hydraulic type drench with rain alarm valve structure as shown in Figure 3: the drench with rain barrier film water inlet control mouthfuls 1.5 of main valve 1 of barrier film connects the barrier films main valve control valve group that drenches with rain, and the control valve group comprises choke valve 3, ball valve 4, check-valves 5, urgent manual ball valve 6, magnetic valve 7, long-range ball valve 8.Barrier film goes out water management mouth 1.6 and is connected by the anti-reset controller 2 of ball valve 9 and hydraulic type.
This alarm valve operation principle is as follows:
When being in set condition, ball valve 4 is opened, and ball valve 6, magnetic valve 7 and ball valve 8 are all closed, and ball valve 9 is opened, and anti-reset controller 2 cuts out automatically, and ball valve 11 is opened, and ball valve 13 and ball valve 14 are opened, and ball valve 15 is closed.Pressure gauge 10 has identical pressure with Pressure gauge 16, and Pressure gauge 12 no pressure show.Pressure switch 17 no hydraulic pressure, the alert tinkling of pieces of jade 18 of waterpower is not worked.Ball valve 19 closes.Ball valve 20,21,22 open.
When one or more situation of the following situation of unexpected appearance, the alarm valve that drenches with rain by set condition to duty: A: magnetic valve 7 is in opening B: ball valve 6 is in opening C: ball is in opening.Because control chamber pressure begins to be released, the alarm valve that drenches with rain begins to open, and when controlled pressure dropped to a certain degree, anti-reset controller 2 was opened automatically.
Even because of misoperation causes ball valve 6,8 and magnetic valve 7 Close All again, therefore the alarm valve that drenches with rain can not cut out yet.Because after one of ball valve 6,8 and magnetic valve 7 are opened, control chamber pressure reduces, and the anti-reset controller of hydraulic type is opened; Behind ball valve 6,8 and magnetic valve 7 Close Alls, the anti-reset controller of hydraulic type can be opened always, and control chamber can not accumulate hydraulic pressure, and the alarm valve that drenches with rain can not cut out.
If valve 9 cuts out (be equivalent to not adorn hydraulic type drench with rain alarm valve), how about is situation? when opening ball valve 6,8 and magnetic valve 7 because of the misoperation Close All, therefore the alarm valve that drenches with rain can cut out.Code requirement is after the alarm valve that drenches with rain is opened, even ball valve 6,8 and magnetic valve 7 are closed because of misoperation, the alarm valve that drenches with rain can not cut out.Therefore the alarm valve that drenches with rain of (or do not adorn hydraulic type drench with rain alarm) is a substandard product to close 9.
Claims (2)
1, the diaphragm type of the anti-reset controller of the band hydraulic type alarm valve that drenches with rain, it comprises the barrier film main valve that drenches with rain, with barrier film a barrier film that the barrier film water inlet control mouth of main valve the is connected main valve control valve group that drenches with rain that drenches with rain, it is characterized in that barrier film goes out the water management mouth and prevents that by pipe valve and hydraulic type reset controller is connected.
2, according to claim 1 with the diaphragm type of the anti-reset controller of the hydraulic type alarm valve that drenches with rain, it is characterized in that the anti-reset controller of hydraulic type comprises valve body, the pressure sensitive hole that is provided with on the valve body, the valve gap that is connected with valve body, establish spring in the valve gap, diaphragm, the piston that is connected with diaphragm, piston-rod lower end connects flap, flap can be located at the sealing of valve body upper valve base.
