Description
Technical field
The utility model belongs to steam heating pipe drainage exhaust field, more specifically to a kind of steam heating pipeline
Steam trap connection.
Background technology
Using steam as it is thermal source heated at present municipal administration heat in be widely used, its cardinal principle be using steam as
Heating agent and heat energy carrier, only it is transported to by self power effect in heating equipment, this embodies one of steam as power source
Face.But under the conditions of disregarding fuel and changing into the thermal efficiency of steam course, the heat energy availability for steam heating agent of analyzing and researching,
That is unit mass heat utilization rate, generally below 60%, utilization rate is low.
The reason for causing above mentioned problem is mainly that steam has some vapor because the reduction of temperature goes out in course of conveying
Now liquefaction condenses phenomenon.In steam heating system, the condensate on the way that steam condenses along tube wall may be by the steam stream of high speed
Band is wrapped up in, forms the high velocity water droplets flowed with steam, fast steam stream wraps up in band, forms the high velocity water droplets flowed with steam, and falls
The condensate on the way of ttom of pipe may also be started again by high velocity air, form " water plug " and with steam flow at high speed, when running into
When situations such as valve, turn or upward pipeline section changes flow direction, water droplet or water plug are hit with pipe fitting or pipe at high speeds
Hit, it is possible to produce " water attack " situation, so that there is phenomena such as noise or vibration, the tight of pipe fitting weld bond can be destroyed when serious
Property, it is to cause major accident to cause fluid leakage.
Utility model content
The purpose of this utility model is to provide a kind of steam heating pipeline steam trap connection, timely discharged in jet chimney
Liquefaction or the water condensed, avoid occurring " water attack " phenomenon in jet chimney, it is ensured that the security and sealing of jet chimney conveying.
A kind of steam heating pipeline steam trap connection of technical solutions of the utility model, the hot duct include instrumentation tubes and set
The heat-insulating cover being placed in outside instrumentation tubes, heat-insulation layer, the steam trap connection peace are filled between the heat-insulating cover and instrumentation tubes
In instrumentation tubes, the steam trap connection includes a threeway, and the threeway is arranged between heat-insulating cover and instrumentation tubes, threeway
Two of which interface on connect instrumentation tubes, drain pipe is connected on the 3rd interface, the drain pipe passes through heat-insulation layer and insulating tube
Set is connected with drain tank.
Preferably, short tube is provided with the heat-insulating cover, the short tube axis is vertical with heat-insulating cover axis, and described three
Lead to and connect the interface of drain pipe and be placed in short tube, the short tube oral area is provided with sealing blind.
Preferably, the interface of the threeway connection drain pipe is provided with orifice filter.
Preferably, the drain pipe connection drain tank end is provided with hydrophobic pipe-in-pipe, is provided with the hydrophobic pipe-in-pipe
Fixation steel plate, drain pipe are fixed by fixation steel plate and U-bolt with hydrophobic pipe-in-pipe, the hydrophobic pipe-in-pipe and heat-insulating cover
It is affixed.
Preferably, the hydrophobic pipe-in-pipe is arranged on the heat-insulating cover of short tube back.
Preferably, the hydrophobic pipe-in-pipe is arranged on short tube outer circumference surface.
A kind of steam heating pipeline steam trap connection of technical solutions of the utility model can timely discharge steam heating pipeline
Interior condensate, but in order to thoroughly effectively exclude the condensate in steam pipeline of jet chimney, the installation site of steam trap connection is also particularly
It is important.The set location of steam trap connection mainly has:Before the low spot of jet chimney and vertical elevated pipeline section;The steam of same slope aspect
Pipeline, in the case of Shun Po 200-300 meters in the case of 400-500 meters, adverse grade;In the steam pipe of long distance delivery
On the way;The curved preceding or minimum point of each compensation for the steam pipe of saturated vapor;The bottom of standpipe;Pressure-reducing valve and control on steam pipe
The valve front position of valve processed;Pipeline section low dot location.
The latent heat that saturated vapor in the range of conventional 0.1-1.2MPa carries is 81 ~ 71%, and sensible heat is 19 ~ 29%, just
Really select and set steam trap connection can reclaim 5%-8% steam thermal energy.
The utility model technology beneficial effect:
A kind of steam heating pipeline steam trap connection of technical solutions of the utility model, it is simple in construction, in heat-insulation layer, no
The insulation of original instrumentation tubes and pipe sleeve is influenceed, can be timely by pipe by the way that steam trap connection to be arranged on to the rational position of pipeline
Condensate discharge in road, avoids the formation of " water plug ", avoids the occurrence of " water attack " phenomenon, it is ensured that the tightness of steam heating pipeline
And security.
