Abstract
A kind of high pressure steam drainage valve station for high steam hydrophobic pipeline, using the special shut-off valve of two positive and negative Double-clacks of high pressure and the high pressure steam drainage valve station of a high pressure steam drainage valve composition complete set.Continuously run under the bad working environments of high-pressure no vapour at the drain valve station, when needing to overhaul and safeguarding, the high-pressure stop valve of special bivalve flap seal can be transferred to lower valve base closing, passage of the cut-out towards high pressure steam drainage valve, open upper valve base and bypass pipe interface channel at the same time, bypass pipe replaces high pressure steam drainage valve hydrophobic temporarily, 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 work efficiency.
Description
Technical field
Patent of the present invention is related to the high steam such as petrochemical industry, nuclear power station, aircraft carrier field, especially continuous production
Cannot be stopped the high pressure steam drainage valve of important process units.
Background technology
Steam trap at present applied to high pressure is very rare, under the bad working environments that high pressure is continuously run for a long time, 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 use electricity
Dynamic shut-off valve replaces drain valve, it is impossible to automatic hydrophobic.By market survey, patent of the present invention can solve this problem completely.
The content of the invention
In order to solve the hydrophobic problem that high pressure continuously runs bad working environments for a long time, patent of the present invention discloses a kind of high pressure length
The high pressure steam drainage valve station of phase operation, it is desirable to provide a kind of to utilize patent of the present invention spy under the operating mode 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 close off high pressure steam drainage valve
Passage, enables high pressure steam drainage valve on-bne repair and replaces the high pressure steam drainage valve station of accessory.
The high-pressure stop valve for wherein forging 12Cr1MOV valve bodies is positive and negative Double-clack, double-valve-seat two way seal face, lower valve base
Controlled for main valve seat and lead to high pressure steam drainage valve passage, bypass tube passage is led in valve seat supplemented by upper valve base, control, and upper valve base has
One orifice channel, can replace high pressure steam drainage valve temporarily.
The flap tuning upper valve base of two high-pressure stop valves in normal work, closes bypass tube passage, while opens logical
Toward high pressure steam drainage valve passage, the work of high pressure steam drainage valve normal operation.
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, cut-out while open upper valve base towards the vapour source of high pressure steam drainage valve, steam and condensation water by upper valve base throttle orifice
Passage replaces high pressure steam drainage valve hydrophobic temporarily by, bypass pipe, 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.
Completed when high pressure steam drainage valve overhauls, then high-pressure stop valve flap be transferred to upper valve base, close bypass tube passage,
The passage towards high pressure steam drainage valve is opened at the same time, and high pressure steam drainage valve works on.This high pressure steam drainage valve station can
To work for a long time under the severe operating mode of high pressure.
The major advantage of patent of the present invention is：
1st, forging 12Cr1MOV valve-body stop valves are special positive and negative two-way flap, the high-pressure stop valve of double-valve-seat, upper valve base
There is an orifice channel, connecting bypass pipe can replace high pressure steam drainage valve hydrophobic temporarily.
2nd, 12Cr1MOV valve body high pressure steam drainage valves are forged, valve body, valve deck, valve seat, spool internals all possess tears open online
Unloading functions, facilitate on-bne repair and replacement.
3rd, the high pressure steam drainage valve station structure is compact, multiple functional, reliable working performance, saves production cost, improves
Work efficiency.
Brief description of the drawings
Attached drawing is：High pressure steam drainage valve station
Embodiment
Patent of the present invention is further illustrated with example below in conjunction with the accompanying drawings
As shown in drawings, patent of the present invention is mainly by stop valve body (1) shut-off valve lower valve base (2) cut-off valve core (3)
Shut-off valve upper valve base (4) graphite packing (5) cut-off disc nut (6) shut-off valve gland nut (7) shut-off valve valve rod (8) cut-off
Valve valve stem nut (9) ends 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) orifice channel (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) passage is led in control, and shut-off valve upper valve base (4) is equipped with a throttling
Hole path (23), can replace high pressure steam drainage valve, shut-off valve valve rod (8) and the cooperation that cut-off valve core (3) is activity temporarily,
There is fixing nut (9) on stop valve body (1) stent, cut-off valve hand wheel (10) can be controlled with adjustable cut-off valve valve rod (8) to be ended
Valve core (3) is up and down.
Cut-off valve core (3) tuning shut-off valve upper valve base (4) of two high-pressure stop valves (1) in normal work, is closed
Tube passage (11) is bypassed, opening leads to high pressure steam drainage valve (22) passage, the work of high pressure steam drainage valve (22) normal operation.
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 cut-out, while opens shut-off valve upper valve base (4), steam and condensation water by cutting
Only the orifice channel (23) of valve upper valve base (4) is by temporarily bypass pipe replaces high pressure steam drainage valve (22) hydrophobic, high at this time
Steam trap (22) is pressed can also to be 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, while is opened and cut
Only valve lower valve base (2), high pressure steam drainage valve (22) work on.Patent high pressure steam drainage valve station of the present invention can exist for a long time
Continuous work under the severe operating mode of high pressure.
