Description

Technical Field

[0001] The present invention relates to the technical field of valves, and particularly to a side-mounted eccentric C-type ball valve. Background Art

[0002] A valve is a device used to control media such as gas, liquid, and gas or liquid containing solid powder in various pipelines and equipment. A valve usually consists of a valve body, a valve cover, a valve seat, a closing member, a driving mechanism, seals, and fasteners, etc. Valves came into being with the emergence of fluid pipelines. With the continuous development of technology and the continuous progress of society, valves are more and more widely used in real life and production, and the C-type ball valve belongs to one type of valve. In our daily life, the C-type ball valve is widely used in industries such as chemical industry, hospitals, and petroleum. In a valve, the valve seat is used to support the fully closed position of the valve core and form a sealing pair. In industries such as coal chemical industry, refining, and metallurgy, when fluid transportation is required, the C-type ball valve is mainly used to transport fluids such as gas and liquid.

[0003] At present, the existing C-type ball valve is easily affected by the impact of fluid velocity, resulting in vibration. The overall structure is not stable enough, causing the valve to become loose, and then overflow and leakage occur everywhere, resulting in poor interception effect of the valve on the fluid and affecting the normal use of the valve body. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A side-mounted eccentric C-type ball valve, comprising:

[0005] A first housing and a second housing, which are shells with a supporting function. The first housing and the second housing are installed at the same height. Bolts are installed at the outer edges of the first housing and the outer edges of the second housing. A feed hole is opened in the middle of the outer side of the first housing, and a discharge hole is opened in the middle of the outer side of the second housing;

[0006] An adjusting mechanism, which is used to control the fluid. The adjusting mechanism is installed on the top of the first housing;

[0007] Wherein, the adjusting mechanism includes a connecting valve rod, the connecting valve rod is rotatably installed in the middle of the top of the first housing, and a seal is installed between the connecting valve rod and the first housing. The bottom end of the connecting valve rod extends into the interior of the first housing. An adjusting round wheel is fixedly installed at the top end of the connecting valve rod. A spherical valve core is fixedly installed at the bottom end of the connecting valve rod. A pin shaft is fixedly installed at the bottom end of the spherical valve core, and the bottom end of the pin shaft is rotatably installed with the bottom of the inner cavity of the first housing. A circular through hole is opened in the middle of the spherical valve core. Rotating the adjusting round wheel clockwise drives the connecting valve rod to rotate, and then drives the spherical valve core to rotate clockwise;

[0008] Rotate the plugging convex block clockwise by 90 degrees using the spherical valve core. At this time, the spherical surface outside the spherical valve core just blocks the tail of the feed hole. Use the spherical surface outside the spherical valve core to fill the gap between the tails of the feed holes and plug the feed hole, thereby cutting off the fluid. At this time, the ball valve is in the closed state;

[0009] This side-mounted eccentric C-type ball valve further includes:

[0010] A stabilizing mechanism for supporting the connecting valve stem. The stabilizing mechanism is installed at the middle of the top of the first housing;

[0011] Among them, the stabilizing mechanism includes a cylindrical barrel. The bottom end of the cylindrical barrel is fixedly installed at the middle of the top of the first housing. The connecting valve stem is rotatably installed at the top of the cylindrical barrel. A first card slot and a second card slot are respectively opened at the middle of the inner cavity of the cylindrical barrel. A self-locking component is installed at the middle of the outer side of the connecting valve stem.

[0012] Preferably, the axis at the center of the first housing coincides with the axis at the center of the second housing, which is convenient for installing the first housing and the second housing. The bolts are evenly distributed at the edges of the outer side of the first housing and the edges of the outer side of the second housing. The evenly distributed bolts can firmly fix the first housing and the second housing.

[0013] Preferably, the spherical valve core is installed inside the first housing, and the pin shaft is installed below the spherical valve core, which is convenient for rotatably supporting the spherical valve core with the pin shaft, making the connection of the spherical valve core reliable.

[0014] By installing the pin shaft at the bottom of the spherical valve core, the bottom of the spherical valve core can be rotatably supported. At the same time, the bottom position of the outer side of the connecting valve stem is rotatably connected to the top of the first housing, and the top of the connecting valve stem rotates with the top of the cylindrical barrel. Furthermore, the spherical valve core and the connecting valve stem are connected at three different positions: the bottom, the middle, and the top, making the rotation adjustment of the spherical valve core and the connecting valve stem stable.

[0015] Preferably, the self-locking component is installed inside the cylindrical barrel, and the position of the self-locking component corresponds to the positions of the first card slot and the second card slot.

[0016] Preferably, the self-locking assembly includes a sector base and a square guide post. The sector base is fixedly installed at the middle outside the connecting valve stem. A rectangular support shell is fixedly installed on the sector surface outside the sector base by screws. A square sliding sleeve is installed at one end of the rectangular support shell away from the connecting valve stem. The square guide post is slidably installed outside the rectangular support shell through the square sliding sleeve. The square guide post extends into the interior of the rectangular support shell. Circular clamping balls and elastic frames are respectively fixedly installed at both ends of the square guide post. The elastic frame is installed inside the rectangular support shell. One end of the elastic frame away from the square guide post is fixedly installed at the middle of the inner wall of the rectangular support shell. When the connecting valve stem drives the whole self-locking assembly to rotate clockwise by 90 degrees, the valve is in the closed state. By using the first card slot and the second card slot which are respectively opened on two lines with an angle of 90 degrees, and by installing the circular clamping ball at the same height as the first card slot and the second card slot, and under the elastic force of the elastic frame, at this time, the square guide post pushes the circular clamping ball outwards, and at this time, the circular clamping ball is embedded into the interior of the second card slot;

[0017] When the connecting valve stem drives the whole self-locking assembly to rotate counterclockwise by 90 degrees, the valve is in the open state. At this time, the circular clamping ball will be embedded into the first card slot, so that the valve will be self-locked in both the closed and open states, thereby making the connecting valve stem more stable and making the spherical valve core not easily affected by fluid impact.

[0018] Preferably, the circular clamping ball is installed outside the rectangular support shell. The square guide post, the circular clamping ball and the elastic frame are installed at the same height. The elastic frame is diamond-shaped. There are three elastic frames, and the three elastic frames are evenly distributed between the square guide post and the inner wall of the rectangular support shell. By using the three elastic frames together to provide elastic force, the elastic supporting force for the square guide post is increased.

[0019] Preferably, an auxiliary component is installed between the top of the inner cavity of the first housing and the top of the spherical valve core. The auxiliary component includes an annular extension edge and a sealing gasket. The top of the annular extension edge is fixedly installed at the middle of the top of the inner cavity of the first housing. The sealing gasket is rotatably installed on the top of the spherical valve core. The connecting valve stem passes through the center of the annular extension edge and the center of the sealing gasket. An annular pad is fixedly installed at the middle of the outer side of the sealing gasket. The bottom of the annular extension edge is embedded between the annular pad and the sealing gasket. A spring is fixedly installed between the top of the annular pad and the top of the inner cavity of the first housing. By using the annular extension edge to block the fluid inside the first housing, and combining with the bottom of the annular extension edge being embedded between the annular pad and the sealing gasket, and the arc surface at the bottom of the sealing gasket fitting the spherical surface at the top of the spherical valve core, sealing is achieved. And by using the elastic force provided by the spring and combining with the action and reaction forces, the annular pad is subjected to a reverse pressing force, so that the annular pad is closely attached to the bottom of the annular extension edge, and it is not easy to have fluid overflow and leakage.

[0020] Preferably, the materials of the sealing gasket and the annular pad are both rubber materials. The springs are evenly distributed along the circumferential direction of the axis at the center of the sealing gasket.

[0021] Preferably, a leakage prevention component is installed between the first housing and the second housing. The leakage prevention component is installed at the same height as the first housing and the second housing. The leakage prevention component includes a sealing ring. The sealing ring is installed between the first housing and the second housing, and the sealing ring is hollow. Round holes are opened at the edge of the outer side of the sealing ring. The bolt passes through the center of the round hole. A support pad ring is fixedly installed between the two corresponding sides of the inner cavity of the sealing ring. When the sealing ring is installed between the first housing and the second housing and the first housing and the second housing are fixed by bolts, at this time, the sealing ring and the support pad ring are compressed and deformed. At this time, the support pad ring supports the inside of the sealing ring, so that the sealing ring fills the gap between the end face of the first housing and the end face of the second housing, and thus it is not easy to have leakage, making full use of the connection between the mechanisms to connect the structures together.

[0022] Preferably, the round holes are evenly distributed at the edge of the outer side of the sealing ring. The materials of the sealing ring and the support pad ring are both rubber materials. By passing the bolt through the center of the round hole, the whole sealing ring is limited, so that the sealing ring will not shift, reducing the influence of external force and the impact vibration during fluid flow, and making the sealing effect good.

[0023] The present invention provides a side-mounted eccentric C-type ball valve. It has the following beneficial effects:

[0024] 1. For this side-mounted eccentric C-type ball valve, when the spherical valve core rotates the plugging protrusion block clockwise by 90 degrees, the spherical surface outside the spherical valve core just blocks the tail of the feed hole. By using the spherical surface outside the spherical valve core to fill the gap between the tails of the feed holes, the feed hole is blocked, thereby shutting off the fluid. At this time, the ball valve is in the closed state.

[0025] 2. For this side-mounted eccentric C-type ball valve, the annular extension edge is used to partition the fluid inside the first housing, and the bottom of the annular extension edge is embedded between the annular gasket and the sealing gasket. Moreover, the arc surface at the bottom of the sealing gasket fits with the spherical surface at the top of the spherical valve core, thereby achieving sealing. By using the elastic force provided by the spring and combining the action and reaction forces, the annular gasket is subjected to a reverse pressing force, so that the bottom of the annular gasket is closely attached to the annular extension edge, making it difficult for the fluid to overflow from the connection between the connecting valve stem and the top of the first housing, and thus it is not easy to have fluid overflow and leakage.

[0026] 3. For this side-mounted eccentric C-type ball valve, the spherical valve core is rotatably supported at the bottom by using a pin shaft. The bottom position on the outside of the connecting valve stem is rotatably connected to the top of the first housing, and at the same time, the top of the connecting valve stem rotates with the top of the cylindrical barrel. As a result, the spherical valve core and the connecting valve stem are connected at three different positions: the bottom, the middle, and the top, making the rotation adjustment of the spherical valve core and the connecting valve stem stable.

[0027] 4. For this side-mounted eccentric C-type ball valve, the first card slot and the second card slot are respectively opened on two lines with an angle of 90 degrees, and the circular card ball is installed at the same height with the first card slot and the second card slot. Under the elastic force of the elastic frame, the square guide post pushes the circular card ball outwards at this time. When the connecting valve stem drives the self-locking component to rotate 90 degrees clockwise and counterclockwise as a whole, the valve will be self-locked in both the closed and open states, thereby making the connecting valve stem more stable and making the spherical valve core not easily affected by the impact of the fluid.

[0028] 5. For this side-mounted eccentric C-type ball valve, the sealing ring is installed between the first housing and the second housing. When the first housing and the second housing are fixed by bolts, the sealing ring and the support gasket ring are compressed and deformed at this time. The support gasket ring supports the inside of the sealing ring, making the sealing ring fill the gap between the end face of the first housing and the end face of the second housing, and thus it is not easy to have leakage.

[0029] 6. For this side-mounted eccentric C-type ball valve, the bolt passes through the center of the round hole, so that the whole sealing ring is limited, and thus the sealing ring will not shift, reducing the influence of external force and the impact vibration during fluid flow, and making the sealing effect good.

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0044] The first embodiment, as Figures 1 - 4 and Figures 7 - 9 and Figure 12 shown, the present invention provides a technical solution: a side-mounted eccentric C-type ball valve, comprising:

[0045] A first housing 1 and a second housing 2, the first housing 1 and the second housing 2 are shells with a supporting function, the first housing 1 and the second housing 2 are installed at the same height, bolts 3 are installed at the outer edges of the first housing 1 and the outer edges of the second housing 2, a feed hole 4 is opened in the middle of the outer side of the first housing 1, and a discharge hole 5 is opened in the middle of the outer side of the second housing 2;

[0046] The axis at the center of the first housing 1 coincides with the axis at the center of the second housing 2, which is convenient for the installation of the first housing 1 and the second housing 2. The bolts 3 are evenly distributed at the outer edges of the first housing 1 and the outer edges of the second housing 2. The evenly distributed bolts 3 can firmly fix the first housing 1 and the second housing 2.

[0047] An adjusting mechanism 6, the adjusting mechanism 6 is used for controlling the fluid, and the adjusting mechanism 6 is installed on the top of the first housing 1;

[0048] Among them, the adjusting mechanism 6 includes a connecting valve rod 61, the connecting valve rod 61 is rotatably installed in the middle of the top of the first housing 1, and a seal is installed between the connecting valve rod 61 and the first housing 1. The bottom end of the connecting valve rod 61 extends into the interior of the first housing 1. An adjusting round wheel 62 is fixedly installed at the top end of the connecting valve rod 61. A spherical valve core 63 is fixedly installed at the bottom end of the connecting valve rod 61. A pin shaft 64 is fixedly installed at the bottom end of the spherical valve core 63. The bottom end of the pin shaft 64 is rotatably installed with the bottom of the inner cavity of the first housing 1. A circular through hole 65 is opened in the middle of the spherical valve core 63. The staff rotates the adjusting round wheel 62 clockwise, so that the connecting valve rod 61 is driven to rotate, and then the spherical valve core 63 is driven to rotate clockwise;

[0049] Rotate the plugging projection block clockwise by 90 degrees using the spherical valve core. At this time, the spherical surface outside the spherical valve core 63 just blocks the tail of the feed hole 4. Use the spherical surface outside the spherical valve core 63 to fill the gap between the tails of the feed hole 4 and plug the feed hole 4, thereby cutting off the fluid. At this time, the ball valve is in the closed state.

[0050] The spherical valve core 63 is installed inside the first housing 1, and the pin shaft 64 is installed below the spherical valve core 63.

[0051] The pin shaft 64 is installed at the bottom of the spherical valve core 63 to rotatably support the bottom of the spherical valve core 63. And the bottom position on the outside of the connecting valve stem 61 is rotatably connected to the top of the first housing 1. At the same time, the top of the connecting valve stem 61 is rotated with the top of the cylindrical barrel 71. Thus, the spherical valve core 63 and the connecting valve stem 61 are connected at three different positions: the bottom, the middle, and the top, making the rotation adjustment of the spherical valve core 63 and the connecting valve stem 61 stable.

[0052] An auxiliary component 8 is installed between the top of the inner cavity of the first housing 1 and the top of the spherical valve core 63. The auxiliary component 8 includes an annular extension edge 81 and a sealing gasket 82. The top of the annular extension edge 81 is fixedly installed at the middle of the top of the inner cavity of the first housing 1. The sealing gasket 82 is rotatably installed on the top of the spherical valve core 63. The connecting valve stem 61 passes through the center of the annular extension edge 81 and the center of the sealing gasket 82. An annular pad 83 is fixedly installed at the middle of the outside of the sealing gasket 82. The bottom of the annular extension edge 81 is embedded between the annular pad 83 and the sealing gasket 82. A spring 84 is fixedly installed between the top of the annular pad 83 and the top of the inner cavity of the first housing 1. Use the annular extension edge 81 to block the fluid inside the first housing 1, and combine with the bottom of the annular extension edge 81 being embedded between the annular pad 83 and the sealing gasket 82, and the arc surface at the bottom of the sealing gasket 82 fits the spherical surface at the top of the spherical valve core 63, thereby achieving sealing. And use the elastic force provided by the spring 84, and combine with the action and reaction forces, so that the annular pad 83 receives a reverse pressing force, and thus the annular pad 83 is closely attached to the bottom of the annular extension edge 81, and it is not easy to have fluid overflow and leakage.

[0053] The materials of the sealing gasket 82 and the annular pad 83 are both rubber materials. The springs 84 are evenly distributed along the circumferential direction of the axis at the center of the sealing gasket 82 to increase the pressing points, thereby making the fit tight.

[0054] The second embodiment, as Figures 1 - 9 shown, on the basis of the first embodiment:

[0055] This side-mounted eccentric C-type ball valve further includes:

[0056] The stabilizing mechanism 7 is used to support the connecting valve stem 61, and the stabilizing mechanism 7 is installed at the middle of the top of the first housing 1;

[0057] Among them, the stabilizing mechanism 7 includes a cylindrical barrel 71. The bottom end of the cylindrical barrel 71 is fixedly installed at the middle of the top of the first housing 1. The connecting valve stem 61 is rotatably installed at the top of the cylindrical barrel 71. The middle of the inner cavity of the cylindrical barrel 71 is respectively provided with a first card slot 72 and a second card slot 73. The middle of the outer side of the connecting valve stem 61 is provided with a self-locking component 74.

[0058] The self-locking component 74 is installed inside the cylindrical barrel 71, and the position of the self-locking component 74 corresponds to the positions of the first card slot 72 and the second card slot 73, which is convenient for realizing self-locking.

[0059] The self-locking component 74 includes a sector base 741 and a square guide post 743. The sector base 741 is fixedly installed at the middle of the outer side of the connecting valve stem 61. A rectangular support shell 742 is fixedly installed on the sector surface of the outer side of the sector base 741 through screws. A square sliding sleeve is installed at one end of the rectangular support shell 742 away from the connecting valve stem 61. The square guide post 743 is slidably installed on the outer side of the rectangular support shell 742 through the square sliding sleeve. The square guide post 743 extends into the interior of the rectangular support shell 742. Circular clamping balls 744 and elastic frames 745 are respectively fixedly installed at both ends of the square guide post 743. The elastic frame 745 is installed inside the rectangular support shell 742. One end of the elastic frame 745 away from the square guide post 743 is fixedly installed at the middle of the inner wall of the rectangular support shell 742. When the connecting valve stem 61 drives the whole self-locking component 74 to rotate clockwise by 90 degrees, the valve is in the closed state. By using the fact that the first card slot 72 and the second card slot 73 are respectively arranged on two lines with an angle of 90 degrees, and using the circular clamping ball 744 and the first card slot 72 and the second card slot 73 are installed at the same height, and under the elastic force of the elastic frame 745, at this time the square guide post 743 pushes the circular clamping ball 744 outwards, and at this time the circular clamping ball 744 is embedded into the interior of the second card slot 73;

[0060] When the connecting valve stem 61 drives the whole self-locking component 74 to rotate counterclockwise by 90 degrees, the valve is in the open state. At this time, the circular clamping ball 744 will be embedded into the first card slot 72, so that the valve will be self-locked in both the closed and open states, thereby making the connecting valve stem 61 more stable and making the spherical valve core 63 not easily affected by fluid impact.

[0061] The circular ball catch 744 is installed on the outer side of the rectangular support shell 742. The square guide post 743, the circular ball catch 744 and the elastic frame 745 are installed at the same height. The elastic frame 745 is diamond-shaped, and there are three elastic frames 745. The three elastic frames 745 are evenly distributed between the square guide post 743 and the inner wall of the rectangular support shell 742. The three elastic frames 745 are used together to provide elastic force and increase the elastic support force for the square guide post 743.

[0062] The third embodiment is as follows Figures 1 - 4 and Figures 7 - 11 shown. Based on the first embodiment:

[0063] A leak-proof component 9 is installed between the first outer shell 1 and the second outer shell 2. The leak-proof component 9 is installed at the same height as the first outer shell 1 and the second outer shell 2. The leak-proof component 9 includes a sealing ring 91. The sealing ring 91 is installed between the first outer shell 1 and the second outer shell 2, and the sealing ring 91 is hollow. Circular holes 92 are formed at the outer edge of the sealing ring 91. The bolt 3 passes through the center of the circular hole 92. A support pad ring 93 is fixedly installed between the two corresponding sides of the inner cavity of the sealing ring 91. When the sealing ring 91 is installed between the first outer shell 1 and the second outer shell 2 and the bolt 3 is used to fix the first outer shell 1 and the second outer shell 2, at this time, the sealing ring 91 and the support pad ring 93 are compressed and deformed. At this time, the support pad ring 93 supports the inside of the sealing ring 91, so that the sealing ring 91 fills the gap between the end face of the first outer shell 1 and the end face of the second outer shell 2, and thus leakage is not likely to occur.

[0064] The circular holes 92 are evenly distributed at the outer edge of the sealing ring 91. The materials of the sealing ring 91 and the support pad ring 93 are both rubber. By passing the bolt 3 through the center of the circular hole 92, the whole sealing ring 91 is limited, so that the sealing ring 91 will not shift, reducing the influence of external force and the impact vibration during fluid flow, and making the sealing effect good.

[0065] During use, first, the staff places the leak-proof component 9 between the first outer shell 1 and the second outer shell 2, and passes the bolt 3 through the circular holes at the edge of the second outer shell 2, the circular holes 92 and the circular holes at the edge of the first outer shell 1 in sequence. At this time, by passing the bolt 3 through the center of the circular hole 92, the whole sealing ring 91 is limited, so that the sealing ring 91 will not shift, and then tightens the nut at the right end of the bolt 3. At this time, the first outer shell 1 and the second outer shell 2 are fixed by the bolt 3;

[0066] When the bolt 3 is used to fix the first outer shell 1 and the second outer shell 2, at this time, the sealing ring 91 and the support pad ring 93 are compressed and deformed. At this time, the support pad ring 93 supports the inside of the sealing ring 91, so that the sealing ring 91 fills the gap between the end face of the first outer shell 1 and the end face of the second outer shell 2;

[0067] At this time, it is connected to an external fluid pipeline through the flange at the right end of the first housing 1, and then the flange at the left end of the second housing 2 is connected to another external fluid pipeline. When the valve is in the open state, the fluid flows into the first housing 1 from the feed hole 4 and flows out from the discharge hole 5 at the left end of the second housing 2;

[0068] When it is necessary to cut off the fluid, the staff rotates the adjusting round wheel 62 clockwise, so that the connecting valve stem 61 is driven to rotate, and then the spherical valve core 63 is driven to rotate clockwise;

[0069] And the blocking protrusion is rotated clockwise by 90 degrees by using the spherical valve core. At this time, the spherical surface outside the spherical valve core 63 just blocks the tail of the feed hole 4. The spherical surface outside the spherical valve core 63 fills the gap between the tails of the feed hole 4 to block the feed hole 4, thereby cutting off the fluid. At this time, the ball valve is in the closed state;

[0070] And the internal fluid of the first housing 1 is blocked by using the annular extension edge 81, and the bottom of the annular extension edge 81 is embedded between the annular gasket 83 and the sealing gasket 82. Moreover, the arc surface at the bottom of the sealing gasket 82 fits the spherical surface at the top of the spherical valve core 63, thereby realizing sealing. And by using the elastic force provided by the spring 84 and combining the action and reaction forces, the annular gasket 83 is subjected to a reverse pressing force, so that the annular gasket 83 is closely attached to the bottom of the annular extension edge 81, and it is not easy to have the situation of fluid overflow and leakage;

[0071] Moreover, the pin shaft 64 is installed at the bottom of the spherical valve core 63 to rotatably support the bottom of the spherical valve core 63. The bottom position on the outer side of the connecting valve stem 61 is rotatably connected to the top of the first housing 1, and at the same time, the top of the connecting valve stem 61 is rotated with the top of the cylindrical barrel 71, so that the spherical valve core 63 and the connecting valve stem 61 are connected at three different positions of the bottom, the middle and the top, making the rotation adjustment of the spherical valve core 63 and the connecting valve stem 61 stable;

[0072] At the same time, when the connecting valve stem 61 drives the self-locking assembly 74 to rotate clockwise by 90 degrees as a whole, the valve is in the closed state. The first card slot 72 and the second card slot 73 are respectively opened on two lines with an angle of 90 degrees, and the circular card ball 744 and the first card slot 72 and the second card slot 73 are installed at the same height. Under the elastic force of the elastic frame 745, the square guide post 743 pushes the circular card ball 744 outwards at this time, and the circular card ball 744 is embedded into the internal of the second card slot 73;

[0073] When the connecting valve stem 61 drives the self-locking assembly 74 to rotate counterclockwise by 90 degrees as a whole, the valve is in the open state. At this time, the circular clamping ball 744 will be embedded in the first clamping groove 72, so that the valve will be self-locked in both the closed and open states, thereby making the connecting valve stem 61 more stable and making the spherical valve core 63 not easily affected by fluid impact.
