Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As shown in Figure 1 to Figure 2, the hydrophobic structure of a kind of jet chimney, including jet chimney 1 and steam trap connection, steam pipe
The horizontal component 101 in road 1 imbeds underground, and the vertical portion 103 of jet chimney 1 passes ground 2, a part for vertical portion 103
On ground 2, a part passes through circular arc transition part between ground more than 2, horizontal component 101 and vertical portion 103 additionally below
Divide 102 connections.
Steam trap connection includes drain pipe the 3, first gate valve 4, the first hydrophobic pipeline I and the second hydrophobic pipeline being arranged in parallel
Ⅱ.First gate valve 4 is welding gate valve or flanged gate valve.It is internal that horizontal component 101 is stretched in drain pipe 3 one end, other end from
Vertical portion 103 goes out to be located in and is provided only with the place of heat-insulation layer and passes.First gate valve 4 is arranged on the vertical portion being exposed on ground 2
Divide the outside of 103 and be connected with drain pipe 3, on the right side of the first gate valve 4, being provided with the first hydrophobic pipeline I and the second drain pipe of parallel connection
Road II.First hydrophobic pipeline I is from left to right disposed with the second gate valve 5, filter 6, steam trap 7 and check-valves (in figure not
Show), condensed water after drain pipe 3 flows successively through the second gate valve 5, filter 6, steam trap 7 and check-valves the most afterwards from discharge outlet
302 discharge.Discharge outlet 302 scene connects DN25 double focusing direct-buried pipe direct-burried to gully.Check-valves is set, prevents the cold of steam trap connection
Backflow can be produced when solidifying water has been discharged into pressure device.Second gate valve 5 is flanged gate valve.It is provided with flange on second hydrophobic pipeline II
Gate valve 9, sets up manual bypass, and when can meet blowing pipeline after hydraulic test of pipeline, a large amount of dewatering needs or condensed water are the most
Time dewatering needs.Because the jet chimney 1 being embedded in underground is the minimum point of whole pipeline, condensed water accumulates in horizontal component
Bottom within 101, so the water inlet 301 of drain pipe 3 stretches into horizontal component 101 inside and is fixed in horizontal component 101
Portion and the bottom of transition portion 102 internal connection, and it is close to the bottom of horizontal component 101.Water inlet 301 is for being provided with 30
The groove of degree angle, it is easier to condensed water is discharged.
It is arranged close to the position of external protection on the jet chimney 1 of heat-insulation layer is provided with anti-as it is shown in figure 1, be provided only with
Canopy 8, prevents rainwater from entering in the external protection of jet chimney 1.
Operation principle of the present utility model:
Opening the first gate valve 4 and the second gate valve 5, flanged gate valve 9 remains off.Due to the pressure in jet chimney 1
Higher than the pressure outside jet chimney 1, condensed water sequentially passes through the first gate valve 4 and the first hydrophobic pipeline I after being pressed into drain pipe 3 after
Discharge from discharge outlet.
If condensed water is more, opening flanged gate valve 9, condensed water is discharged from the second hydrophobic pipeline II simultaneously.Second
Hydrophobic pipeline II can also effectively get rid of the hydrops during water pressure test.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
