Abstract
A kind of saturated vapor spray head for steam annihilator, with cylindrical sprayer body, the steam channel being made of the steam (vapor) outlet of the steam inlet for the cone being successively connected, cylindrical throat and woodruff key flute profile is equipped in the sprayer body, the width dimensions of the steam (vapor) outlet are identical as the diameter of the throat；The steam inlet is equipped with the internal screw thread of connection steam supply pipe, and the lower part of the sprayer body is equipped with hexagonal prism body section.The effective range of the utility model is remote, and the distribution of steam of injection is uniform, and it is relatively large that single spray head is formed by vapour curtain area, can form complete steam curtain with relatively small number of spray head.
Description
Technical field
The utility model relates to steam annihilators, and in particular to a kind of saturated vapor spray for steam annihilator
Head.
Background technique
Steam annihilator is widely used in the fire-fighting of petrochemical industry, combines to form steam using multiple steam jets
Curtain is effectively isolated fire source, reduces fire spreading, and be rapidly reached the purpose of fire smothering.Existing steam jet, mostly taper
Nozzle arrangements, steam spray distance is short, is unevenly distributed, and it is small that single spray head is formed by vapour curtain area, to form complete steaming
Spray head quantity required for vapour curtain is relatively more.
Summary of the invention
The purpose of this utility model is that in view of the above-mentioned problems, providing a kind of saturated vapor spray for steam annihilator
The effective range of head, the steam jet is remote, and the distribution of steam of injection is uniform, and single spray head is formed by vapour curtain area relatively
Greatly, complete steam curtain can be formed with relatively small number of spray head.
Realizing the technical solution of above-mentioned purpose is: a kind of saturated vapor spray head for steam annihilator has cylinder
The sprayer body of shape, the sprayer body is interior to be equipped with by the steam inlet for the cone being successively connected, cylindrical throat and semicircle
The steam channel of the steam (vapor) outlet composition of key-way shape, the width dimensions of the steam (vapor) outlet are identical as the diameter of the throat.
The above-mentioned saturated vapor spray head for steam annihilator, the steam inlet are equipped with the interior of connection steam supply pipe
The lower part of screw thread, the sprayer body is equipped with hexagonal prism body section.
The utility model makes the steam a fluid stream office into spray head by the steam inlet of cone and the combination of laryngeal inlet
Portion is shunk, and flow velocity increases；By the steam (vapor) outlet of woodruff key flute profile make spray steam stream formed area coverage it is relatively large and
Uniform vapour curtain；Steam (vapor) outlet groove bottom uses arc surface, and the resistance for being subject to steam in ejection process is small, and forms steam point
The relatively uniform steam curtain steam flow of cloth.
The effective range of the utility model is remote, and the distribution of steam of injection is uniform, and single spray head is formed by vapour curtain area phase
To larger, complete steam curtain can be formed with relatively small number of spray head.
The utility model can be mounted on the saturated vapor steam supply pipe of steam annihilator by welding or being connected through a screw thread
On the road, easy to assembly.
Detailed description of the invention
Fig. 1 is the saturated vapor spray head main sectional view that this is used for steam annihilator.
Fig. 2 is the saturated vapor spray head top view that this is used for steam annihilator.
In figure: 1, sprayer body；2, steam inlet；3, throat；4, steam (vapor) outlet；5, internal screw thread；6, hexagonal prism body section.
Specific embodiment
Specific embodiment of the present utility model is illustrated in conjunction with attached drawing.
As shown in Figure 1, Figure 2, this saturated vapor spray head for being used for steam annihilator has cylindrical sprayer body 1, described
It is equipped with along axis by the steam inlet 2 for the cone being successively connected, cylindrical throat 3 and woodruff key flute profile in sprayer body 1
The steam channel that steam (vapor) outlet 4 forms, the width dimensions of the steam (vapor) outlet 4 are identical as the diameter of the throat 3.
The above-mentioned sheet with cylindrical sprayer body 1 is used for the saturated vapor spray head of steam annihilator, is pacified by welding
Mounted in the saturated vapor steam supply pipe road of steam annihilator.
The sheet that attached Example provides is used for the saturated vapor spray head of steam annihilator, and the lower part of the steam inlet 2 is set
There is the internal screw thread 5 of connection steam supply pipe, the lower part of the sprayer body 1 is equipped with hexagonal prism body section 6, is connected through a screw thread and is mounted on steam
The saturated vapor steam supply pipe road of extinguishing device.
