Away from equal.This structure ensure that when refractory powder entered that cross section of axle center, inlet opening cincture as far as possible,
Water uniformly can mix with refractory powder.
It is surrounded with inlet opening at least two cross section on separated material ring, wants according to castable needed for fire-resistant workbench
The difference asked, the quantity of inlet opening on regulation separated material ring.Inlet opening on adjacent cross sectional is dislocatedly distributed, with
It is easy to water mix with refractory powder uniformly further.
Being provided with on inlet connector and the annular slot of batch mixing passage concentric, separated material ring one end snaps in annular snap
Groove, the separated material ring other end is provided with and the fixing movable buckle being clasped, this structure avoid water directly from every
The junction of material ring and water supply connector flows into batch mixing passage, thus causes that water and refractory powder are uneven to be mixed.
A diameter of 1mm-4mm of inlet opening, this structure can be avoided refractory powder to enter separated material ring in a large number connecing with charging
In gap between head medial wall, and the gap between separated material ring and water supply connector medial wall is caused to be plugged,
Or inlet channel is plugged.It is difficult to owing to separated material ring takes out in water supply connector, therefore, reduces inlet opening
Diameter, can reduce workman and clear up the time needed for spray gun.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of spray gun for fire-proof spray coating construction of the present invention；
Fig. 2 is the sectional view of inlet connector of the present invention.
Detailed description of the invention
With reference to Fig. 1, a kind of spray gun for fire-proof spray coating construction, including shower nozzle 1, mixing tube 2 and powder
Pipe 3, mixing tube 2 one end is provided with discharging joint 4, and mixing tube 2 is connected with shower nozzle 1 by discharging joint 4,
Being provided with the water inlet pipe 6 connected with discharging joint 4 on the sidewall of discharging joint 4, mixing tube 2 other end is arranged
Inlet connector 5, mixing tube 2 is had to be connected with powder pipe 3 by inlet connector 5.
Seeing figures.1.and.2, discharging joint 4 is provided with batch mixing passage 42 and intake tunnel 43, batch mixing leads to
Road 42 is the interface channel between shower nozzle 1 and mixing tube 2, and refractory powder enters batch mixing passage from mixing tube 2
42, intake tunnel 43 is the interface channel between batch mixing passage 42 and water inlet pipe 6, and water enters from water inlet pipe 6
Enter intake tunnel 43.It is provided with in discharging joint 4 and the separated material ring 7 of batch mixing passage 42 concentric, separated material ring
Interface channel between batch mixing passage 42 and intake tunnel 43 is cut off by 7, it is to avoid water is from water inlet pipe 6 way flow
Enter and directly mix with refractory powder, thus in causing discharging joint 4, the refractory powder of diverse location mixes with water
Close uneven.
With reference to Fig. 2, separated material ring 7 is provided with a cross section, b cross section and c cross section, three cross sections are all arranged
Have around separated material ring 7 sidewall inlet opening 71, a diameter of 2mm of inlet opening 71, on same cross section adjacent enter
Spacing between water hole 71 is identical.The wherein inlet opening 71 on a cross section and inlet opening 71 phase on c cross section
The most concordant, stagger with the inlet opening 71 on a cross section in the inlet opening 71 on b cross section.Set in intake tunnel 43
Being equipped with annular groove 44, annular groove 44 avoids the lateral wall of separated material ring 7 to be close to the medial wall of discharging joint 4,
Water flows through water inlet pipe 6, intake tunnel 43, annular groove 44 and inlet opening 71 successively, finally enters batch mixing and leads to
In road 42, mix uniformly with refractory powder.
With reference to Fig. 2, discharging joint 4 left end medial wall is provided with and the annular snap of batch mixing passage 42 concentric
Groove 41, the left end of separated material ring 7 can be inserted in annular slot 41, and the right-hand member lateral wall of separated material ring 7 is provided with
Movable buckle 72, discharging joint 4 right-hand member medial wall is provided with the fixing buckle coordinated with movable buckle 72
45.Separated material ring 7 moves axially, and separated material ring 7 left end inserts in annular slot 41, and movable buckle 72 squeezes
Press solidly and determine after buckle 45 produces elastic deformation through fixing buckle 45, it is achieved separated material ring 7 right-hand member and discharging joint
4 snap connection.This structure realizes separated material ring 7 and is fixed on discharging joint 4.
Seeing figures.1.and.2, shower nozzle 1 is provided with charging aperture, inlet connector 4 left end is provided with on lateral wall
Can be inserted into the annular convex rib 46 of charging aperture.
With reference to Fig. 1, the inwall of mixing tube 2 is provided with water accepting layer, water accepting layer can avoid water in mixing tube 2 just
Mix with refractory powder, thus cause and on mixing tube 2 inwall, be stained with castable, thus reduce mixing tube 2 and have
The refractory powder transit passage of effect.Mixing tube 2 is positioned at inlet connector 5 one end and is provided with observation window 21, observation window
Whether 21 exist castable so that checking mixing tube 2 to be positioned at observation window 21, and this structure can avoid water inlet pipe
6 too early water flowings, and cause water to flow directly in powder pipe 3.If water mixes with refractory powder in powder pipe 3
Symphysis becomes castable, thus blocks powder pipe 3, can seriously increase the maintenance cost of spray gun.
Separated material ring in the present invention also can be connected with discharging joint screw thread, thus simplifies the internal junction of discharging joint
Structure.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited to
This, those of ordinary skill in the art should be understood that the present invention includes but not limited to accompanying drawing and is embodied as above
Content described in mode.Any it is intended to be included in power without departing from the function of the present invention and the amendment of structural principle
In the scope of profit claim.
