Description
Technical field
This utility model relates to fire-fighting control field, specifically a kind of special pressure relief ball valve of high-pressure fine water mist fire-extinguishing system.
Background technology
Fine water mist fire-extinguishing system is used for the application places such as archives and electric machine room at present.Such application places is to water stain
Loss requires that relatively other places are high, and fine water mist fire-extinguishing system is after closedown, although valve has been switched off, but rear segment pipe pressure
Power is because being unable to reach service pressure, and the shower nozzle being installed on pipeline i.e. cannot spray water mists, thus occurs dripping
Phenomenon, to shower nozzle just to paper document or electrical equipment cause unnecessary secondary damage.
Utility model content
This utility model purpose is to provide a kind of simple structure, cheap, easy to use high-pressure water mist fire-extinguishing system
Unite special pressure relief ball valve.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of special pressure relief ball valve of high-pressure fine water mist fire-extinguishing system, including water supply connector, valve body, water out adapter, described valve
Body is rectangular shape, and water supply connector and water out adapter are arranged on two faces that valve body is symmetrical, and valve inner is provided with spheroid,
Described ball interior is provided with sprue and secondary channels, and described sprue runs through spheroid, the vertical sprue of described secondary channels, and incites somebody to action
Running through with outside spheroid in the middle part of sprue, described valve body is provided with valve rod, valve rod controls spheroid, described valve body is provided with and lets out
The mouth of a river.
Further, sluicing flange it is provided with between described spheroid and discharge opening.
Further, described water supply connector, water out adapter are provided with nitrile rubber o type circle with the junction of valve body.
Preferably, the spheroid of described valve inner is provided around valve seat.Fixing spheroid, prevents position from moving.
As preferably, described valve body is provided with sluicing plug and regulation plug, as described spheroid rotates underaction, then
Adjust described regulation plug and the compression degree of depth of described sluicing plug respectively.
The beneficial effects of the utility model are:
Pressure relief ball valve is designed to Highpressure Tee ball valve by this utility model so that during valve opening state, current directly lead to
Cross water inlet and the outlet at straight-through two ends, hence into valve rear end；And during valve-closed state, current from valve rear end by
Outlet flows back to valve, discharge opening discharge.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model can be by right
Require that the multitude of different ways limiting and covering is implemented.
As it is shown in figure 1, the open a kind of special pressure relief ball valve of high-pressure fine water mist fire-extinguishing system of this utility model, connect including entering water
1, valve body 2, water out adapter 4, described valve body 2 is in rectangular shape, and described water supply connector 1 is arranged on valve body 2 with water out adapter 4
On two symmetrical faces, water supply connector 1, water out adapter 4 seal with nitrile rubber o type 7 circle with the junction of valve body 2.
Valve body 2 is internally provided with spheroid 6, and described spheroid 6 is internally provided with sprue 12 and secondary channels 13, described sprue
12 run through spheroid 6, the described vertical sprue 12 of secondary channels 13, and run through outside with spheroid 6 in the middle part of sprue 12, described valve body
Being provided with valve rod 11 on 2, valve rod 11 controls spheroid 6, and described valve body 2 is provided with discharge opening 3, rotary valve rod 11, and valve rod 11 is controlled
The rotation of spheroid 6 processed, when the sprue 12 of spheroid 6 is by water supply connector 1 and water out adapter 4 internal run-through, pressure relief ball valve is being opened
Opening under state, High-Pressure Water directly flows into the spheroid 6 in valve body 2 from described water supply connector 1, then flows out after water out adapter 4,
Whole runner design is simple, and resistance to water-flow loss is little；Rotary ball valve, when the secondary channels 13 of spheroid is by water out adapter 4 and discharge opening 3
Time through, pressure relief ball valve in off position under, High-Pressure Water cannot flow into valve body 2 from water supply connector 1 again, it is achieved that to current
Control.After Tong Shi, the High-Pressure Water in segment pipe then passes back into spheroid 6 by water out adapter 4, through spheroid 6 and discharge opening 3 it
Between the sluicing flange 9 that arranges, and discharge from described discharge opening 3, thus segment pipe quick pressure releasing after realizing.
It is provided with sluicing flange 9 between described spheroid 6 and discharge opening 3.Have employed flange connection, decrease elbow peace
Bending radius needed for dress so that valve mechanism is the compactest, installation takes up room less.
Spheroid 6 within described valve body 2 is provided around valve seat 8, when spheroid 6 normally works, internal pressure maximum up to
25MPa, for preventing the skew of described spheroid 6 from causing leakage, four direction is respectively mounted described valve seat 8 and compresses, preventing stress not
Uniformly.
It is provided with sluicing plug 10 and regulation plug 5 on described valve body 2, as described spheroid 6 rotates underaction, then distinguishes
Adjust regulation plug 5 and the compression degree of depth of described sluicing plug 10.
Above-described this utility model embodiment, is not intended that the restriction to this utility model protection domain.Any
Amendment, equivalent and the improvement etc. made within spirit of the present utility model and principle, should be included in this utility model
