Description
Technical field
This utility model belongs to extinction using gas equipment field, especially relates to a kind of constant pressure type container value.
Background technology
In outer stored-pressure type automatic fire extinguishing system, because extinguishing chemical bottle group bears limited pressure, promote nitrogen need to pass through air relief valve
Enter extinguishing chemical bottle group, provide constant-voltage power for fire extinguishing system；When extinguishing chemical bottle group does not work, air relief valve is closed
Under, answer bubble-free to leak.Domestic existing like product container value and air relief valve exist simultaneously, wasting space, and pressure value can not
Adjust it is impossible to adapt to the extinguishing chemical bottle group of different refitting amounts, and the safety of extinguishing chemical bottle group cannot be ensured.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides one kind can adjust startup pressure according to initial set value
Power, have the constant pressure type container value of decompression concurrently.
This utility model solves its technical problem and be the technical scheme is that a kind of constant pressure type container value, including valve body,
Can in valve body the valve rod of movement and position-limit mechanism, described valve stem seal is connected in valve body, and described valve body is provided with for driving
The air inlet that gas passes through, described valve body is provided with pressure regulating device and the exhaust passage with the cooperation of this pressure regulating device, and this aerofluxus is led to
Road can connect air inlet, valve inner and the external world；Described exhaust passage can be coordinated so that pressure regulating device with valve rod, position-limit mechanism
There is the first working position and the second working position, when being in the first working position, the partial high pressure gas in described exhaust passage can
Promote and move on pressure regulating device, described exhaust passage is connected with the external world, the partial high pressure gas push valve in described exhaust passage
Bar moves down to open container value；When being in the second working position, exhaust passage is isolated by pressure regulating device with the external world, described aerofluxuss
Gases at high pressure in passage promote valve rod to move down to open container value.During original state, set the pressure to valve body for the pressure regulating device,
I.e. the pressure value of exhaust passage blocked by pressure regulating device, enters the startup gas in container value by air inlet and enters through exhaust passage
Enter in valve body, when starting the setting value that gas pressure is more than pressure regulating device original state, a part of high pressure gas are known from experience pressure regulation
Mechanism pushes up upwards so that exhaust passage connection is extraneous, discharges a part of gases at high pressure, another part high pressure gas are known from experience to valve rod top
End applies a downward pressure, promotes valve rod to move down, thus connecting air inlet and gas outlet, opens container value.When releasing
Venting body is equal to or less than initial set value, pressure regulating device homing to pressure.When completing to start, position-limit mechanism is applied to valve rod
Plus a restoring force upwards, air inlet do not connect with gas outlet.
Further, described pressure regulating device includes mounting seat, the elastic component that can move up and down in mounting seat, is used for adjusting
The regulating part of elastic component decrement and the blocking piece offseting with elastic component one end, described blocking piece is coordinated with exhaust passage.By adjusting
Moving up and down of part can change the decrement to elastic component, thus changing pressure regulating device to the pressure value blocking exhaust passage,
It is adapted to different container bottle, adaptability is high.
Further, described position-limit mechanism includes return unit, the location division in valve body and the company being sheathed on valve rod
Fitting, described connector is offseted with location division with valve interior wall sealing cooperation, described return unit one end, and its other end is butted on connection
Part.Elastic component is set between valve rod and connector, it is to avoid elastic component shifts, and structure is more stable.
Further, described position-limit mechanism also includes revolving part, and this revolving part is coordinated with valve rod, can move up and down regulation multiple
The decrement of position part.By the decrement moving up and down change return unit of revolving part, regulating valve stem can be facilitated to move up and down
Distance, such that it is able to according to different container bottle, cooperative voltage regulation device sets different Opening pressures, structure is more flexible.
Open Here pressure is the minimum operating pressures that promoting valve rod to move down, because in ampoule, discharge pressure scope is less, in order to
There is a small amount of leakage in the bottle that starts avoiding pressure larger, and lead to promote valve rod to move down to cause to open by mistake and open, by revolving part
Setting is so that exist during less leakage rate it is impossible to promote valve rod to move down open container value, so that air relief valve has had appearance concurrently
The function of device valve.
Further, described position-limit mechanism also includes opening tool, this opening tool and the valve rod with valve interior wall sealing cooperation
