Description
Technical field
The utility model relates to a kind of venturi steam trap, more specifically to a kind of no air gas is stifled and steam
Vapour is locked and is able to satisfy a kind of inner cavity stepped hole type nozzle venturi steam trap of block steam and drain water function.
Background technique
Conventional vapor drain valve maximum liquid discharge capacity is certain value under certain pressure difference at present, therefore for operating condition load variations
When conventional vapor drain valve can not adapt to technological parameter and worked normally, therefore, the mode of replacement can only be taken.It is more main
It is that the hydrophobic valve arrangement of conventional vapor is complex, components are more and cooperation required precision is very high, so components have slight mill
It will cause cooperation accuracy decline and seal failure after damage, steam caused to leak in the jet chimney of rear end, " water attack " is caused to damage
Bad gas utilization unit and tearing jet chimney.
Except this, all there is air gas and block up in conventional vapor drain valve, i.e., air is non-condensable gas, can not be dissolved in condensed water,
Cavity space is occupied when air enters in steam drainage valve chamber, causes condensed water cannot be introduced into and drain valve architecture is caused to lose
Effect.Steam vapour lock：When superheated steam enters in hydrophobic valve chamber, the process for being condensed in water is more slow, causes drain valve defeated
Water is slow.The problem of due to these, accelerating equipment and inner wall of the pipe burn into reduces the running efficiency of equipment and causes to steam
Vapour is detained using equipment or jet chimney lime set, influences the rate of heat exchange of heating equipment.
Utility model content
The technical problems to be solved in the utility model is：In no on-off structure, without sealing pair and it is able to satisfy steam trap
Block steam and drain water function, to eliminate, air gas is stifled and steam vapour is locked.
The utility model includes：Fixed plate-type flange, gasket, stepped hole type nozzle, tubular shell and connecting flange,
Feature is：
A, the bumping post on stepped hole type nozzle, the groove of lower end are provided with gasket, stepped hole type nozzle and fixation
The connection of plate-type flange inner hole thread, the lower end of fixed plate-type flange and tubular shell are welded to connect, the other end of tubular shell with
Connecting flange is welded to connect.
B, the internal diameter of stepped hole type nozzle one end is successively arranged taper hole, connecting hole, aperture, and the internal diameter of the other end is successively set
There are macropore, mesoporous, mesoporous is communicated with aperture.One end outer diameter of stepped hole type nozzle is successively arranged turret head, bumping post, the other end
Outer diameter be equipped with screw thread.
The utility model not only includes a stepped hole type nozzle, for the operating condition for meeting different flow, in the board-like method of fixation
The stepped hole type nozzle of mountable different pore size in the gear hole of the blue hole Zhong Tai lower end.
The utility model can provide a user one kind and high and low temperature is discharged using equipment suitable for steam pipeline and steam
Condensed water, air and not condensated gas and a kind of internal inner cavity stepped hole type nozzle venturi steam trap without opening and closing element.Platform
The design of rank hole type nozzle input end taper hole, cold condensate and non-condensable gas (air) quickly enter stepped hole type nozzle chamber
It is interior, prevent cold condensate and non-condensable gas (air) to be detained pipeline, to solve the problems, such as " water attack ".Stepped hole type nozzle step hole
Inner cavity design, can make high temperature lime set form vortex-like steam flow at step, steam can be prevented to spray from stepped hole inner cavity, to meet
Block steam and drain water function.The phenomenon that no valve mechanism for opening/closing is to prevent steam vapour lock avoids because steam is occupied full of valve insertion body
Space causes high temperature lime set to cannot be introduced into and be stranded in pipeline and cause " water attack " accident.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
