Abstract
Combined balls (6, 7) or combined butterfly valves of a ball valve or a butterfly valve are composed of a wedge ball (6) or a wedge plate, and ball clacks (7) or butterfly clacks. After a valve rod (4) drives the wedge ball (6) or the wedge plate to rotate by 90 degrees according to the track of a right angle groove (5), the lower wedge of an anti-loosing wedge plug (1) is released, and pressure relieving holes (8) offset to be sealed. The ball clacks (7) or the butterfly clacks are opened to be closely attached to the valve base, and the valve is closed. The valve rod (4) drives the wedge ball (6) or the wedge plate to move upwards, the wedge ball (6) or the wedge plate is stopped by the anti-loosing wedge plug (1) and a spacing handle (3), the pressure relieving holes (8) are communicated with each other, the ball clacks (7) or the butterfly clacks disengage from the valve seat, and the pressure is balanced; when the wedge ball (6) or the wedge plate reversely rotates by 90 degrees, the valve is opened.
Description
The invention relates to the invention of ball valve and butterfly valve sealing configuration.
Ball valve, gate valve, stop valve, stopcock, butterfly valve, membrane valve are the opening/shutting valves that the controlling plumbing fixtures medium is connected or blocked.Wherein: ball valve, butterfly valve best performance are more.But because metallic seal is paid easy biting the end of knot when compressing, easy plucking during rotation.So, the ball valve of Metal Ball, metal butterfly plate and metal seat valve sealing or general hard material matched seal, the extremely difficult manufacturing of butterfly valve.The valve seat of existing ball valve, butterfly valve generally all adopts flexible barrier materials such as nylon, teflon, rubber, and serviceability temperature is lower than 150 ℃, has therefore placed restrictions on the using scope of ball valve, butterfly valve greatly.
Closely during the last ten years, adopt build-up wear-resistant wiping, high temperature resistant, corrosion resistant Hardmetal materials on sealing surface both at home and abroad, the sealing configuration that adopts elastic seat and elastic floating valve seat is also arranged, but all fail the biting the end of knot of fine solution sealing surface, plucking problem.I have also applied for two patents (85204475 to Patent Office of the People's Republic of China, 87100516.6) be to adopt flexible steel ring, four arc-shaped connecting rods, strut the valve sealing structure of bracing type of combination ball or combination butterfly plate, all be in order to solve biting the end of knot between sealing surface, plucking, development High Temperature High Pressure ball valve, this difficult problem of butterfly valve.
The objective of the invention is to provide a kind of and pay a not biting the end of knot, not bracing type High Temperature High Pressure ball valve, the butterfly valve seal structure of plucking, superior performance through evidence sealing.
This structure is device combination ball or a combination butterfly plate in ball valve or butterfly valve body.The centre of combination ball or combination butterfly plate is that wedge-type spheroid or wedge both sides have ball clack or butterfly lobe.Have on the valve body anyhow and intersect, laterally revolve the trough with straight angle that turn 90 degrees.When valve need be opened, the spacing handle of valve rod is up to peak in trough with straight angle, promptly limited, valve rod also compresses locking tapered plug or tapered sleeve, and at this moment wedge-type spheroid or wedge are also related up, relief hole communicates, it is in a basic balance to import and export both sides pressure, and ball clack or butterfly lobe are drawn close to wedge-type spheroid or wedge, form the gap between sealing surface after, valve rod drives combination ball or combination butterfly plate together with spacing handle and revolves and turn 90 degrees, and valve wide open opens.When valve need be closed, after opposite direction revolved and turn 90 degrees when valve rod drove combination ball or combination butterfly plate and does with unlatching in trough with straight angle together with spacing handle, throwing off locking tapered plug or tapered sleeve moves downwards, force wedge-type spheroid or wedge hyposphene, relief hole dislocation sealing, strut both sides ball clack or butterfly lobe, be adjacent to sealing, the valve contract fully to valve seat.
The present invention and prior art are compared, not only kept ball valve, the butterfly valve fluid resistance is little, flow to unrestricted, outside the advantages such as switch rapidly, highly low, in light weight, structure length is short, be integrated in one but also gate valve is opened and closed advantage such as the most laborsaving, that the stop valve sealing is the most reliable, can significantly reduce or eliminate biting the end of knot, plucking and frictional force between sealing surface like this, improved valve working life greatly, alleviate valve opening and closing power greatly, significantly enlarged the using scope of ball valve, butterfly valve.
The concrete structure of invention is born by following embodiment and accompanying drawing:
Accompanying drawing is a kind of High Temperature High Pressure ball valve sealing structure figure that proposes according to the present invention.
Stem Mut (2) is rotated counterclockwise, valve rod (4), wedge-type spheroid (6), spacing handle (3) is in trough with straight angle (5), and uplink synchronization is to peak, and the locking tapered plug (1) on limited handle of valve rod (4) (3) and the Stem Mut (2) is simultaneously spacing, up and the ball clack (7) of wedge-type spheroid (6) is gone up relief hole (8) when communicating, it is in a basic balance to import and export both sides pressure, and ball clack (7) is drawn close to wedge-type spheroid (6), forms gap (as the accompanying drawing position) between sealing surface.Stem Mut (2) continues rotation, valve rod (4), combination ball (6) (7), spacing handle (3) stop up in trough with straight angle (5), and the Stem Mut (2) of being forced to make peace rotates simultaneously, reach 90 when spending, runner hole in the wedge-type spheroid (6) on runner hole and the valve seat communicates fully, and valve wide open opens.
Stem Mut (2) drives valve rod (4), 90 degree are pass in combination ball (6) (7), spacing handle (3) dextrorotation in trough with straight angle (5), (as the accompanying drawing position), promptly limited, can not continue rotation, if continue rotary valve rod nut (2), it is descending that valve rod (4) is thrown off locking tapered plug (1), and wedge-type spheroid (6) is to capable relief hole (8) the dislocation sealing that communicates with ball clack (7) of hyposphene, and ball clack (7) is adjacent to valve seat, form sealing, the valve contract fully.
Utilize this structure both can design, make high temperature, high-pressure ball valve and the butterfly valve product of new range, again can be, connect size by the connection form of existing ball valve, gate valve, stop valve, the substituted type series product are made in the design of usage requirement method of switching.
Claims (2)
1, High Temperature High Pressure ball valve or butterfly valve have combination ball or combination butterfly plate in the valve pocket of valve body, when valve need be closed, wedge-type spheroid or wedge were descending, and two ball clacks or butterfly lobe strut to two sealing surface of seats and be adjacent to, and form sealing; And when valve need be opened, wedge-type spheroid or wedge were up, and two ball clacks or butterfly lobe leave two sealing surface of seats, drew in to the center, make leave the gap between sealing surface after, revolve again and turn 90 degrees, valve wide open is opened, it is characterized in that:
Have on A, described High Temperature High Pressure ball valve or the butterfly valve body anyhow and intersect, laterally revolve the trough with straight angle that turn 90 degrees, spacing handle and wedge-type spheroid or the wedge synchronous with it move by 90 degree trough with straight angle tracks,
B, described combination ball or combination butterfly plate reach the ball clack or the butterfly lobe that match with the inclined-plane by the wedge-type spheroid of being with the inclined-plane or wedge and combine.
2, High Temperature High Pressure ball valve according to claim 1 or butterfly valve is characterized in that: on combination ball or the combination butterfly plate pressure relief device is arranged.
