Abstract
The utility model high pressure steam drainage valve station, using the high pressure steam drainage valve station of the special shut-off valve of two positive and negative Double-clacks of high pressure and a high pressure steam drainage valve composition complete set.Drain valve station continuous operation under the bad working environments that high temperature and pressure does not stop vapour, when needing to overhaul and safeguard, the high-pressure stop valve of special bivalve flap seal can be transferred to lower valve base closing, the channel of high pressure steam drainage valve is led in cutting, open simultaneously upper valve base and bypass pipe interface channel, bypass pipe temporarily replaces high pressure steam drainage valve, and high pressure steam drainage valve can on-bne repair and replacement spool accessory at this time.The high pressure steam drainage valve station structure is compact, multiple functional, saves production cost, improves working efficiency.
Description
Technical field
The utility model relates to arrive the high steams fields, especially continuous production such as petrochemical industry, nuclear power station, aircraft carrier
Cannot stop the high pressure steam drainage valve of important process units.
Background technique
It is very rare applied to the steam trap of high pressure at present, under the bad working environments of the long-term continuous operation of high pressure, generally
Drain valve is all difficult to meet working condition requirement.The high pressure steam line of some power plant can not find suitable drain valve, can only be using electricity
Dynamic shut-off valve replaces drain valve, is unable to automatic hydrophobic.By market survey, the utility model can solve this problem completely.
Summary of the invention
In order to solve the hydrophobic problem of the long-term continuous operation bad working environments of high pressure, the utility model discloses a kind of high pressure is long
The high pressure steam drainage valve station of phase operation, it is desirable to provide a kind of to utilize the utility model spy under the operating condition of high-pressure no vapour
The high pressure steam drainage valve station of system opens bypass tool flow tube and replaces high pressure steam drainage valve, simultaneously closes off high pressure steam drainage valve
Channel enables high pressure steam drainage valve on-bne repair and replaces the high pressure steam drainage valve station of accessory.
Wherein forging the high-pressure stop valve of 12Cr1MOV valve body is positive and negative Double-clack, double-valve-seat two way seal face, lower valve base
Lead to high pressure steam drainage valve channel, valve seat supplemented by upper valve base for main valve seat control, bypass tube passage is led in control, and upper valve base has
One orifice channel can temporarily replace high pressure steam drainage valve.
The flap tuning upper valve base of two high-pressure stop valves in normal work is closed bypass tube passage, is opened simultaneously logical
Toward high pressure steam drainage valve channel, high pressure steam drainage valve operates normally work.
When high pressure steam drainage valve needs Maintenance and Repair, the flap of two high-pressure stop valves is transferred to lower section, closes master
Valve seat, cutting lead to the vapour source of high pressure steam drainage valve, open simultaneously upper valve base, steam and condensed water by the throttle orifice of upper valve base
Channel passes through, and bypass pipe temporarily replaces high pressure steam drainage valve hydrophobic, and high pressure steam drainage valve can with on-bne repair and more at this time
Part is changed, high pressure steam line can also be run as usual.
It is completed when high pressure steam drainage valve overhauls, then high-pressure stop valve flap is transferred to upper valve base, close bypass tube passage,
The channel towards high pressure steam drainage valve is opened simultaneously, high pressure steam drainage valve works on.This high pressure steam drainage valve station can
To work under the severe operating condition of high pressure for a long time.
The major advantage of the utility model is:
1, forging 12Cr1MOV valve-body stop valve is the high-pressure stop valve of special positive and negative two-way flap, double-valve-seat, upper valve base
There is an orifice channel, connecting bypass pipe temporarily can replace high pressure steam drainage valve hydrophobic.
2,12Cr1MOV valve body high pressure steam drainage valve is forged, valve body, valve deck, valve seat, spool internals all have tears open online
Unloading functions facilitate on-bne repair and replacement.
3, the high pressure steam drainage valve station structure is compact, multiple functional, reliable working performance, saves production cost, improves
Working efficiency.
Detailed description of the invention
Attached drawing 1 are as follows: high pressure steam drainage valve station
Specific embodiment
The present invention will be further described with example with reference to the accompanying drawing
As shown in the picture, for the utility model mainly by stop valve body (1), shut-off valve lower valve base (2) ends valve core
(3), shut-off valve upper valve base (4), graphite packing (5) end disc nut (6), shut-off valve gland nut (7), shut-off valve valve
Bar (8), shut-off valve valve stem nut (9) end valve hand wheel (10), bypass connecting pipe (11), drain valve helmet (12), hydrophobic valve deck
(13), hydrophobic valve body (14), hydrophobic spool (15), seal spool pad (16), drain valve filter screen (17), drain valve sealing cushion for cover
(18), drain valve valve block (19), hydrophobic valve nut (20), drain valve bolt (21), high pressure steam drainage valve (22), throttle orifice are logical
Road (23) composition.
The cut-off valve core (3) of its mesohigh stop valve (1) is positive and negative Double-clack double-valve-seat two way seal face, under shut-off valve
Valve seat (2) is main valve seat, and extra high pressure steam drain valve (14) channel is led in control, and shut-off valve upper valve base (4) is equipped with a throttling
Hole path (23) can temporarily replace high pressure steam drainage valve, and shut-off valve valve rod (8) and cut-off valve core (3) are movable cooperations,
Have fixture nut (9) on stop valve body (1) bracket, adjustable shut-off valve valve rod (8) the control cut-off of cut-off valve hand wheel (10)
Valve core (3) is up and down.
The cut-off valve core (3) of two high-pressure stop valves (1) in normal work, tuning shut-off valve upper valve base (4) are closed
It bypasses tube passage (11), opens and lead to high pressure steam drainage valve (22) channel, high pressure steam drainage valve (22) operates normally work
Make.When high pressure steam drainage valve (22) needs Maintenance and Repair, two high-pressure stop valve cores (3) are transferred to shut-off valve lower valve base
(2), the vapour source of high pressure steam drainage valve (22) is led in cutting, opens simultaneously shut-off valve upper valve base (4), steam and condensed water by cutting
Only the orifice channel (23) of valve upper valve base (4) passes through, and bypass pipe temporarily replaces high pressure steam drainage valve (22) hydrophobic, high at this time
Steam trap (22) are pressed can also to run as usual with on-bne repair and replacement accessory, high pressure steam line.When high steam is dredged
Water valve (22) maintenance is completed, then high-pressure stop valve core (3) is transferred to shut-off valve upper valve base (4) and closes bypass, is opened simultaneously and is cut
Only valve lower valve base (2), high pressure steam drainage valve (22) work on.The utility model high pressure steam drainage valve station can exist for a long time
Continuous work under the severe operating condition of high pressure.
