Description
Technical field
Exempting to wash away sealing surface regulating valve suitable for what oil, chemical industry and other industry used the present invention provides a kind of,
Shut-off valve use can be done, mesohigh pipeline is particularly suitable for.
Technical background
Currently, domestic regulating valve, shut-off valve, generally main by valve rod, valve stem nut, valve deck, valve body, valve seat, flap etc.
Part is wanted to form, main seal pattern has plane, conical surface etc..Its disadvantage is the sealing of valve and adjusting flow position
It is valve seat, at flap sealing.When closing valve, the valve seat on valve is in close contact with flap realizes sealing, valve opening and into
When row adjusts flow, pipeline medium flows out between valve seat and flap, the sealing surface of medium direct erosion valve seat and flap, sealing
It face and is easily washed away and damages by medium, valve seal performance is caused to fail.Especially lower valve the case where High Pressure Difference adjusts flow
The door service life is shorter.
Invention content
It is an object of the invention to overcome existing valve sealing structure technical disadvantages, innovative design go out valve seal position and
Water outlet position is the structure on two different location of valve, solves the direct erosion sealing of valve medium when adjusting flow
Face, sealing surface easily damage, the disadvantage that valve seal performance is poor, service life is short.
The present invention solve technical problem the technical solution adopted is that：The present invention is by handle, valve stem nut, valve rod, valve deck, valve
Body, bushing, upper piston, lower piston, spring composition, the built-in bushing of valve body, the built-in upper piston of bushing, lower piston, spring.
Bushing is equipped with water outlet, and water outlet lower end is equipped with sealing ring, and upper piston upper end is equipped with sealing ring.
Bushing inner cavity is equipped with step, and lower piston bottom end is equipped with step, and lower piston is equipped with medium flow field through-hole.
It is an advantage of the invention that：Valve mechanism is simple, switch flexibly, valve regulated flow when, valve sealing ring and lower work
End cylindrical surface, which is mutually fitted close, beyond the Great Wall forms sealing pair, and valve seal position and water outlet position are positions different in valve two
It sets, solves the disadvantage that the valve direct erosion sealing surface of medium, valve sealing face when adjusting flow are protected, valve is close
Sealing property is good, and service life is long, and the operating mode of flow is adjusted especially suitable for High Pressure Difference.
Present invention will be further explained below with reference to the attached drawings and examples.
Attached drawing 1 is the main sectional view of the embodiment of the present invention.
1 handle in figure, 2 valve stem nuts, 3 valve decks, 4 valve rods, 5 bushings, 6 valve bodies, 7 sealing rings, 8 upper pistons, 9 sealing rings,
It is living under 10 lower pistons, 11 springs, A water outlets, B upper pistons and lower piston contact surface, C bushings step, D lower pistons lower end step, E
Fill in medium flow field through-hole.
Specific implementation mode
In the accompanying drawings, one kind exempt to wash away sealing surface regulating valve by handle (1), valve stem nut (2), valve deck (3), valve rod (4),
Bushing (5), valve body (6), sealing ring (7), upper piston (8), sealing ring (9), lower piston (10), spring (11), water outlet (A),
Bushing step (C), lower piston lower end step (D), the hole flow of media (E) composition.Bushing (5), bushing (5) are housed in valve body (6)
Built-in upper piston (8), lower piston (10), spring (11).Bushing (5) is equipped with water outlet (A), lower end water outlet (A) of bushing (5)
Equipped with sealing ring (9), upper piston (8) upper end is equipped with sealing ring (7), and bushing (5) inner cavity is equipped with step (C), lower piston (10) bottom
End is equipped with step (D), and lower piston (10) is equipped with medium flow field through-hole (E).
A kind of sealing mechanism for exempting to wash away when sealing surface regulating valve is closed is by bushing (5), upper piston (8), sealing ring (9)
Composition, after valve completely closes, the sealing ring (9) on upper piston (8) lower end cylindrical surface and bushing (5) is mutually fitted close,
Valve seal pair is formd, the circulation of medium has been blocked, valve is closed.
A kind of adjusting flow mechanism that exempting to wash away sealing surface regulating valve be by bushing (5), upper piston (8), lower piston (10),
Spring (11), water outlet (A) and sealing ring (9) composition.When Open valve, valve rod (4) drives upper piston (8) to move up,
Simultaneously lower piston (10) under the thrust of spring (11) with upper piston (8) synchronize move up, upper piston during valve opening
(8) with the contact surface of lower piston (10) (B) while by sealing ring (9).When the step (D) of lower piston (10) lower end is moved to lining
When covering step (C) of (5), the upper transverse plane of lower piston (10) is flushed with water outlet (A) lower end plane, and valve is now arranged in initially
Open state, the step (C) that step (D) the arrival bushing (5) of lower piston (10) lower end is at this time, lower piston (10) is limited solid
Surely it cannot continue to move up.It is further continued for Open valve, upper piston (8) continues to move up, lower piston (10) and upper piston (8)
Contact surface (B) start gap occur, the gap be known as adjust mouth, medium from the adjusting mouth flow to water outlet (A) reach valve chamber,
Output valve.Valve is continued on, upper piston (8) continues to move up, and adjusts open height and is gradually increased, and reaches most when adjusting mouth
When big position, valve is all turned on.Adjustment adjusts the size of open height to realize flow-rate adjustment, reaches valve regulated flow.
It, can be in the end face of upper piston (8) and lower piston (10), surfacing in order to improve valve regulated mouth anti-medium performance of flushing
One layer of anti-impact brush material, the service life is longer for valve.
A kind of scouring mechanism of exempting from for exempting to wash away sealing surface regulating valve is by bushing (5), lower piston (10) and sealing ring (9) group
At.When Open valve, when the step (D) of lower piston (10) lower end reaches step (C) of bushing (5), lower piston (10) is limited
Position is fixed from and continues to move up, and one kind, which is exempted to wash away sealing surface feature, just to be had been carried out, at this time lower piston (10) upper end cylinder
The sealing ring (9) of lower end water outlet (A) on face and bushing (5) is mutually fitted close, and is formd sealing pair, has been blocked medium
Circulation, protects valve sealing face, valve sealing face just exempts to wash away.
A kind of cutting sealing loop mechanism of exempting from that exempting to wash away sealing surface regulating valve is by upper piston (8), lower piston (10), sealing
Enclose (9), spring (11) composition.For valve during being turned on and off, upper piston (8) and the contact surface (B) of lower piston (10) are same
When pass through sealing ring (9), sealing ring (9) will not be cut.
The present invention operation principle be：Handle (1) is rotated counterclockwise, valve stem nut (2) rotates, living in valve rod (4) drive
Plug (8) move up, while lower piston (10) under the thrust of spring (11) with upper piston (8) synchronize move up, live instantly
After plug (10) is fixed, sealing ring (9) phase of lower end water outlet (A) on lower piston (10) upper end cylindrical surface and bushing (5)
It is mutually fitted close, forms sealing pair, blocked the flowing of medium, valve sealing face is protected, valve sealing face is just
Exempt to wash away, valve, which continues on, can be adjusted flow.Rotate clockwise handle (1), valve stem nut (2) rotation, valve rod (4)
Upper piston (8) is driven to move down, after upper piston (8) and lower piston (10) contact, upper piston (8) and lower piston (10) are together
It moves down, the contact surface (B) while process sealing ring (9) of upper piston (8) and lower piston (10), when the lower face of upper piston is arrived
Up to sealing ring (9) lower end when, valve is closed.
