Abstract
The utility model through type high pressure reverse bucket steam trap is a kind of steam trap for high steam pipe network and high pressure steam heating equipment.The valve body casts for WC6 steel alloys, and main valve seat is stellite, and drain valve uses movable valve plug; automatic positioning, hydrophobic valve inlet passageways are equipped with filter screen, and protection drain valve will not block; valve upper cover is equipped with filter screen blowdown bolt, can online blowdown purging pipeline.Hydrophobic valve inlet passageways are designed with loose joint cutting ferrule and are connected to U-shaped diversion pipe, and all parts are all mounted on valve deck, and for inlet and outlet flange in the same horizontal line on valve deck, installation piping is convenient.
Description
Technical field
The utility model through type high pressure reverse bucket steam trap is related to a kind of high pressure steam drainage valve, in particular for
The drain valve of high steam pipe network and high pressure steam heating equipment.
Background technology
Currently, the high pressure reverse bucket steam trap generally used in the market is all to use bottom in and top out, side low into height
The mounting means gone out, without filter screen, very inconvenient Pipe installing and maintenance.
Invention content
In order to solve high pressure reverse bucket steam trap bottom in and top out, low in and high out very inconvenient Pipe installing in side is asked
Topic, the utility model structure innovation through type high pressure reverse bucket steam trap, drain valve inlet and outlet are same on valve deck
On one horizontal line, facilitate Pipe installing, filter screen is equipped on hydrophobic valve inlet passageways, valve deck is equipped with blowdown bolt, can be
Line blowdown and purging pipeline.It is equipped with articulation cutting ferrule in hydrophobic valve inlet passageways, U-shaped diversion pipe is connected and steam and condensed water is drawn
Enter in reverse bucket, U-shaped diversion pipe can ensure that reverse bucket is under water seal always and work.Drain valve main valve plug is designed as free work
Dynamic, main valve plug is drawn to valve seat by the attraction that pressure difference generates before and after drain valve, and drain valve is closed in main valve plug self-centering, close
Sealing property is good, and service life is long.
Description of the drawings
Attached drawing 1 is：Through type high pressure inverted bucket steam trap
In attached drawing：Valve body (1) U-shaped diversion pipe (2) loose joint cutting ferrule (3) valve deck (4) valve bonnet seal pad (5) filter screen (6) is arranged
Dirty bolt (7) valve seat positioning sleeve (8) valve seat (9) main valve plug (10) auxiliary valve core (11) spool guide rod (12) reverse bucket holder (13)
Rack connecting plate (14) spool guide sleeve (15) lever pivot pin (16) spool pivot pin (17) lever (18) reverse bucket pivot pin (19) is vented
Hole (20) reverse bucket (21) pollution discharging plug (22).
Specific implementation mode：
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in the picture, through type high pressure reverse bucket steam trap is by valve body (1) U-shaped diversion pipe (2) loose joint cutting ferrule
(3) the secondary valve of valve deck (4) valve bonnet seal pad (5) filter screen (6) blowdown bolt (7) valve seat positioning sleeve (8) valve seat (9) main valve plug (10)
Core (11) spool guide rod (12) reverse bucket holder (13) rack connecting plate (14) spool guide sleeve (15) lever pivot pin (16) spool
Pivot pin (17) lever (18) reverse bucket pivot pin (19) gas vent (20) reverse bucket (21) pollution discharging plug (22) forms.
Drain valve imports and exports flange on valve deck in same horizontal line, and hydrophobic valve inlet is equipped with filter screen (6), has on valve deck
Blowdown bolt (7) blowdown and purging pipeline, hydrophobic valve inlet passageways can be equipped with a loose joint cutting ferrule (3), loose joint cutting ferrule (3) online
It is connected to U-shaped diversion pipe (2), U-shaped diversion pipe (2) introduces steam and condensed water in reverse bucket (21), when just starting, reverse bucket
(21) it is fallen down by the weight of itself, drain valve is in open state, and the air and water at low temperature in pipeline pass through U-shaped diversion pipe
(2) enter in reverse bucket (21), air is passed through by reverse bucket (21) top aperture and is discharged through hydrophobic valve seat (9), and condensed water is continuous
Into liquid level rises to hydrophobic valve seat (9) drain valve and drained outward by front and back pressure difference, and when steam enters in reverse bucket, steam is not
Break into fashionable, reverse bucket (21) interior steam forms density contrast with condensed water in drain valve, generates water seal, and there are in reverse bucket (21)
Steam so that reverse bucket (21) is generated rising buoyancy, it is upward that reverse bucket (21) interlocks lever (18) band movable valve plug guide rod (12)
Mobile, guide rod (12) drives auxiliary valve core (11) and main valve plug (10) closes drain valve, and main valve plug (10) is freely movable leans on
Drain valve is automatically closed in the attraction of pressure difference before and after drain valve, and main valve plug (10) self-centering, good seal performance, abrasive forces are small,
Service life is long.When steam does not enter back into drain valve, the steam part in reverse bucket (21) is small from reverse bucket (21) top
Hole (22) by with condensed water mixing after the heat dissipation of hydrophobic valve chest at condensed water, a part of steam in reverse bucket (21)
Also condensation becomes condensed water, and reverse bucket (21) loss of buoyance is fallen down, and reverse bucket (21) interlocks lever (18) band movable valve plug and is oriented to
Bar (12) moves down, and spool guide rod drives auxiliary valve core (11) and main valve plug (10) to lift off a seat (9), and drain valve is opened, and coagulates
It bears water and is discharged rapidly by pressure difference before and after drain valve.When steam be again introduced into reverse bucket (21) it is interior when, reverse bucket (21) rises again
Lever (18) and spool guide rod (12) are interlocked, auxiliary valve core (11) main valve plug (10) closes drain valve, continuously and automatically circulation industrial
Make, reaches block steam and drain water purpose.The drain valve is multiple functional, favorable working performance, is that a kind of very practical through type high pressure is hung upside down
Bucket steam trap.
