Abstract
A kind of decompression fire-fighting sluice valve includes valve rod, valve body and valve deck composition, and the lower end of valve rod is fixedly installed with rubber flashboard, is equipped with decompressor in the water outlet of body wall；Decompressor is made of removable orifice plate, the orifice plate fixing seat being mounted on the removable orifice plate one end, the spring being mounted between removable orifice plate and orifice plate fixing seat；The utility model installs a decompressor by the water outlet in valve body, so that water outlet is soft, the water flowed out will not surge and vacuole.
Description
Technical field
The utility model belongs to pipeline valve technical field, and in particular to be a kind of reasonable in design, utility function
Very strong Novel firefighting gate valve.
Background technique
Fire-fighting sluice valve is mainly used for controlling the fluid stopping by force of liquid in pipeline, has been widely used, due to entering fire-fighting
Hydraulic pressure in bolt in gate valve is generally relatively high, the water surge flowed out and vacuole；The structure of common fire valve is to use
The way of pressure reducing orifice is installed additional in water outlet；And install the cost of manufacture that pressure reducing orifice increases product additional, effect of easing stress instead
Undesirable, the present inventor is directed to such technical disadvantages, restudies the internal structure of fire-fighting sluice valve, this case is given birth to therefrom.
Summary of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of reasonable in design, low manufacture cost,
The good Novel firefighting gate valve of using effect.
The utility model is achieved through the following technical solutions: a kind of decompression fire-fighting sluice valve, include valve rod, valve body and
Valve deck composition, it is characterised in that: rubber flashboard is fixedly installed in the lower end of the valve rod, in the water outlet of body wall
Decompressor is installed.
The decompressor is by removable orifice plate, the orifice plate fixing seat being mounted on the removable orifice plate one end, is mounted on
Spring composition between removable orifice plate and orifice plate fixing seat.
Removable orifice plate portion cylinder composition in T shape, removable orifice plate inside is hollow cavity.
The beneficial effects of the utility model embodiment is: compared with prior art, the utility model passes through going out in valve body
One decompressor is installed, so that water outlet is soft, the water flowed out will not surge and vacuole at the mouth of a river.
Detailed description of the invention
The utility model is described in detail with reference to the accompanying drawing.
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the decompressor in the utility model.
Fig. 3 is the removable orifice plate schematic diagram in Fig. 2.
Following is the specific name respectively identified in figure: 1, handwheel；2, valve rod；3, rubber flashboard；4, valve body；5, decompression dress
It sets；6, valve deck；501, orifice plate fixing seat；502, spring；503, removable orifice plate.
Specific embodiment
As shown in Figures 1 and 3, a kind of decompression fire-fighting sluice valve includes that valve rod 2, valve body 4 and valve deck 6 form, in the valve
The lower end of bar 2 is fixedly installed with rubber flashboard 3, and rubber flashboard 3 makees upper and lower displacement movement under the drive of valve rod 2, to make
It obtains valve to open or close, decompressor 5 is installed in the water outlet of 4 inner sidewall of valve body, decompressor 5 can be effectively relieved
The pressure of water outlet.
The decompressor 5 is by removable orifice plate 503, the orifice plate fixing seat being mounted on 503 one end of removable orifice plate
501, the spring 502 being mounted between removable orifice plate 503 and orifice plate fixing seat 501 forms.
The cylinder in T shape of removable orifice plate 503 forms, and is hollow cavity inside removable orifice plate 503.
When valve opening, rubber flashboard 3 is moved up, the decompression that high pressure water is arranged after flowing into from water inlet by water outlet
It after device 5 depressurizes, flows directly out and, be discharged milder.
