DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the implementation of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the embodiments of the utility model are within the scope of protection of the utility model.

[0033] Referring to the accompanying drawings, a repose angle discharge valve in an example of the present embodiment has a main body including a ball valve structure, and the ball valve structure includes a valve body 1, a valve cover 2, a ball core 3, a rotationally driven valve stem 4, a support shaft 5 and a valve seat 6.

[0034] The valve cover 2 is connected to the valve body 1, the valve seat 6 is arranged in the valve body 1, the ball core 3 is located in the valve body 1, and the ball core 3 is arranged between the valve cover 2 and the valve seat 6. The main body of the repose angle discharge valve adopts the traditional ball valve structure, which can be used as the basis for structural layout, can be adapted to the common pipeline path longitudinal, the connection size is relatively more standard, and the versatility is improved. It can even be made using the original ball valve structure, which is almost the same as the overall structural size (such as length) of the ordinary conventional ball valve on the pipeline and can be interchanged and more practical.

[0035] Among them, one end of the ball core 3 is provided with a supporting circular hole 7, and the supporting circular hole 7 is connected with the supporting shaft 5 by sleeve arrangement. A corresponding shaft sleeve can be arranged between the supporting circular hole 7 and the supporting shaft 5 so that they can rotate relatively more smoothly and stably. The supporting shaft 5 is connected and installed on the valve body 1;

[0036] The other end of the ball core 3 is provided with a connecting portion 31 (which can be in the form of a square hole, etc.), and the connecting portion 31 is fixedly connected to the rotary drive valve stem 4, so that the rotary drive valve stem 4 can cooperate to drive the ball core 3 to rotate and switch positions, and the rotary drive valve stem 4 is installed on the valve body 1, and the valve body 1 cooperates to support the rotary drive valve stem 4 to rotate. The support shaft 5 is coaxially arranged with the rotary drive valve stem 4, and can stably support the ball core 3 to rotate around the axis. Among them, the ball core 3 has an outer spherical surface 8, and the outer spherical surface 8 of the ball core 3 is sealed and matched with the valve seat 6 to realize the valve switch. An elastic element 9 (such as a spring) is also provided between the valve seat 6 and the valve body 1. The elastic element 9 keeps the valve seat 6 in contact with the outer spherical surface 8 of the ball core 3. Combined with the support shaft 5 and the rotation drive valve stem 4 of the ball core 3, a stable high sealing structure is formed, and the rotation axis of the ball core 3 will not change (such as floating). The valve seat 6 can maintain contact and cooperation with the outer spherical surface 8 of the ball core 3 under the elastic force of the elastic element 9. When the valve is sealed and closed, it is not affected by the medium pressure on both sides (input side and output side), thereby ensuring the closing and sealing effect.

[0037] An opening cavity 10 is provided on the ball core 3, and the medium channel of the valve cover 2 is set as a connecting hole 14. The outer end of the connecting hole 14 is provided with a step mouth 15. A bushing blanking straight pipe 16 is matched and installed in the connecting hole 14. The bushing blanking straight pipe 16 can be directly matched and lined in the connecting hole 14 for installation and connection, which is more compact in the ball valve structure; wherein, a flange 17 is provided on the upper end of the bushing blanking straight pipe 16, and the flange 17 is arranged in the step mouth 15, and a height-adjusting gasket 18 is also provided between the flange 17 and the step mouth 15, and the height-adjusting gasket 18 cooperates to adjust the extension distance of the bushing blanking straight pipe 16, so that the repose angle spacing can be debugged and adjusted, so that the repose angle spacing (i.e., the gap) of the valve is adjustable, the valve has good versatility and a wide range of application, and the number and specifications (such as thickness) of the height-adjusting gasket 18 can be set according to needs. The lower end of the bushing discharge straight tube 16 extends into the open cavity 10 of the ball core 3; the open cavity 10 has a planar material receiving inner cavity side wall 19 (i.e., the chamber side wall of the open cavity 10), and the planar material receiving inner cavity side wall 19 is a planar side wall that will cooperate with the material receiving so as to smoothly cooperate with the repose angle to discharge the material. The opening cavity 10 also has a first opening area 11, a second opening area 12 and a discharge opening area 13. The first opening area 11 is located between the discharge opening area 13 and the second opening area 12, and the second opening area 12 and the discharge opening area 13 are respectively arranged on both sides of the first opening area 11. The first opening area 11 is connected to the second opening area 12 to form a straight pipe connection port for a straight pipe (i.e., a bushing discharge straight pipe 16) to extend into and relatively rotate and avoid. During operation, the position of the bushing discharge straight pipe 16 is relatively fixed, and the ball core 3 is driven by the rotary driving valve stem 4 to rotate (back and forth). During the rotation of the ball core 3, the straight pipe connection port can avoid the (relatively fixed position) bushing discharge straight pipe 16 to prevent the bushing discharge straight pipe 16 from interfering with the rotation of the ball core 3; the first opening area 11 is arranged oppositely (face to face) to the plane receiving cavity side wall 19, for example, the position relatively below (i.e., the bottom) of the first opening area 11 on the ball core 3 is the plane receiving cavity side wall 19, so as to form a repose angle matching structure. Of course, the first opening area 11, the discharge opening area 13 and the second opening area 12 can also be directly connected to form an opening. The ball core 3 structure with the opening cavity 10 cooperates with the valve seat 6 on one side, so that the valve cavity does not accumulate material, reducing the occurrence of abnormalities such as valve jamming and scratching caused by (hard) particles accumulating in the cavity. The valve can adjust the distance between the bushing discharge straight pipe 16 and the ball core 3 when closing to ensure that a repose angle suitable for the granular medium is formed to form a seal, and ensure that the valve cavity does not accumulate material when closing, thereby reducing the occurrence of abnormalities such as valve jamming and scratching caused by (hard) particles accumulating in the cavity.

[0038] Its working principle is that when the ball core 3 rotates to the valve closed state, the plane receiving cavity side wall 19 faces upward, and the first opening area 11 is at the position corresponding to the bushing feeding straight tube 16, the bushing feeding straight tube 16 and the plane receiving cavity side wall 19 will smoothly form a repose angle matching structure, and the particles in the medium will be discharged with the bushing feeding straight tube 16 and accumulated on the (lower) plane receiving cavity side wall 19 to form a repose angle matching structure. The distance between the bushing feeding straight tube 16 and the plane receiving cavity side wall 19 is the repose angle matching structure. The outer spherical surface 8 of the ball core 3 cooperates with the valve seat 6 to seal and close the valve, thereby cutting off the flow of liquid or gas in the medium; when the ball core 3 rotates to the valve open state, the outer spherical surface 8 of the ball core 3 cooperates with the valve seat 6 to open the valve, and the second opening area 12 is at the position corresponding to the bushing discharge straight pipe 16, and the discharge opening area 13 rotates with the ball core 3 to face the middle of the valve seat 6, and the particles on the side wall 19 of the plane receiving cavity and the medium in the bushing discharge straight pipe 16 can pass through the valve seat 6 and be output through the valve.

[0039] The repose angle discharge valve adopts a ball valve structure as the main body to optimize the overall structure so that the valve is more versatile and easier to manufacture, wherein the bushing discharge straight pipe 16 cooperates with the ball core 3 (having a first opening area 11, a second opening area 12, and a third opening area) and the valve seat 6, not only forming a repose angle matching structure, but also being able to cooperate to cut off the gas or liquid in the medium when the valve is closed (to prevent gas and liquid from passing through the valve), wherein the repose angle matching spacing can be adjusted by raising the gasket 18, so that it can be used for more particles of different specifications and has a wider range of applications, filling the gap that the repose angle valve cannot smoothly cut off gas and liquid in the closed state, and overcoming the problem that it cannot be used for particles of different specifications.

[0040] The following optimization or further explanation may be performed based on the above embodiments.

[0041] For example, the ball core 3 rotates with the rotation drive valve stem 4 to have a valve closing position and a valve opening position. When the ball core 3 is in the valve closing position, the plane material receiving cavity side wall 19 is located directly below the bushing material discharge straight tube 16, the plane material receiving cavity side wall 19 is in a horizontal state, and there is a material receiving fitting clearance (i.e., the repose angle fitting spacing) between the plane material receiving cavity side wall 19 and the lower end of the bushing material discharge straight tube 16, and the outer spherical surface 8 of the ball core 3 cooperates with the valve seat 6 to cut off and close the valve. When the ball core 3 is in the valve opening position, the plane material receiving cavity side wall 19 is located at the rear side of the bushing material discharge straight tube 16 (i.e., the lateral position), the outer spherical surface 8 of the ball core 3 cooperates with the valve seat 6 to open the valve, and there is a separation space between the valve seat 6 and the outer spherical surface 8 for the medium to pass through.

[0042] For another example, the height-adjusting gasket 18 includes stacked unit gaskets; the height-adjusting gasket 18 can be stacked and adjusted in height by setting the number of unit gaskets as required, so as to adjust the distance that the bushing blanking straight tube 16 extends into, that is, to adjust the repose angle between the lower port where the bushing blanking straight tube 16 extends into and the plane receiving inner cavity side wall 19 to coordinate the spacing size.

[0043] In addition, the optimization is that the medium channel of the valve body 1 is provided with a step hole 20, the outer ring of the valve seat 6 has a step structure, and the outer ring of the valve seat 6 is sleeved in the step hole 20; a fire-proof graphite ring 21 is also provided between the outer ring of the valve seat 6 and the inner ring of the step hole 20, and a groove ring is provided on the outer ring of the valve seat 6, and the fire-proof graphite ring 21 is arranged in the groove ring; an O-ring 22 (i.e., an O-type sealing ring) is also provided between the outer ring of the valve seat 6 and the inner ring of the step hole 20; the O-ring 22 is arranged on the outer channel of the fire-proof graphite ring 21 to play a fire-proof role, protect the O-ring 22, and avoid sealing failure of the O-ring 22. The outer channel of the valve seat 6 is also equipped with a step pressure ring 23, and the elastic element 9 is arranged between the step pressure ring 23 and the valve body 1. There is also an assembly space for the O-ring 22 between the step pressure ring 23 and the valve seat 6. The step pressure ring 23 is sleeved in the valve seat 6. A protective gasket can also be arranged between the step pressure ring 23 and the O-ring 22 to prevent the O-ring 22 from deforming and squeezing into the gap between the step pressure ring 23 and the valve body during use. The elastic element 9 adopts a spring (such as a disc spring or a cylindrical spring, etc.). The fireproof graphite ring 21, O-ring 22 (i.e., O-type sealing ring) on ​​the valve body 1 and the valve seat 6, as well as the step pressure ring 23 and the elastic element 9 cooperate to form a bidirectional pressure-bearing sealing structure (such as a valve seat double piston structure). Regardless of whether the medium acts in the forward or reverse direction, the valve seat can cooperate with the ball core 3 to seal, and the valve seat 6 has reliable sealing performance.

[0044] In addition, a valve stem seat 25 with a packing device 24 is provided on the valve body 1. The rotary driven valve stem 4 is connected to the valve stem seat 25. The valve stem seat 25 is used to cooperate with the support of the rotary driven valve stem 4. The packing device 24 is used to cooperate with the rotary driven valve stem 4 to seal during operation. A bracket 26 is provided on the valve stem seat 25. An actuator 27 (such as a pneumatic or electric actuator 27) is installed on the bracket 26. The actuator 27 is transmission-connected to the rotary driven valve stem 4, and the rotary driven valve stem 4 is driven by the actuator 27 to rotate. This is a mature technology and will not be elaborated on.

[0045] The valve cover 2 is connected to the valve body 1 by fasteners; the support shaft 5 has a base 30, the base 30 is connected to the valve body 1 by fasteners, and the base 30 is located on the outside of the valve body 1; the valve stem seat 25 is connected to the valve body 1 by fasteners. If fasteners such as bolts and screws are used for connection, the entire valve body structure is easy to disassemble and assemble, and the technology is mature.

[0046] The plane receiving cavity side wall 19 of the opening cavity 10 of the core 3 may be provided with a material gathering concave hole 29, so that the particles are more stable and concentrated when stacked on the plane receiving cavity side wall 19. For example, the material gathering concave hole 29 is a spherical concave hole.

[0047] In addition, it can be optimized that when the ball core 3 is in the valve opening position, the plane receiving cavity side wall 19 is located on the rear side of the bushing unloading straight tube 16, and the plane receiving cavity side wall 19 is in an upright state, and the particles on the plane receiving cavity side wall 19 are easy to fall.

[0048] For example, the first opening area 11 and the plane material receiving cavity side wall 19 are arranged relatively up and down, the unloading opening area 13 is relatively located on the left side of the plane material receiving cavity side wall 19, and the second opening area 12 is relatively located on the right side of the plane material receiving cavity side wall 19; the unloading opening area 13, the first opening area 11 and the second opening area 12 are arranged in the same circumferential direction, and the circumferential direction is perpendicular to the axis of the rotary driving valve stem 4, so that when the rotary driving valve stem 4 drives the ball core 3 to rotate back and forth in the circumferential direction, the unloading opening area 13, the first opening area 11 and the second opening area 12 can rotate and switch positions along the circumferential direction, so that the bushing unloading straight pipe 16, the valve seat 6 and the outer spherical surface 8 of the ball valve can cooperate to operate.

[0049] As an additional optimization, the second opening area 12 of the ball core 3 also has a rotation limit portion 28 (which can be set to an arc-shaped edge), and the rotation limit portion 28 matches the rotationally driven valve stem 4. When the ball core 3 rotates to open the valve, the rotation limit portion 28 cooperates with the outer wall of the bushing feed straight pipe 16 to rotate into place.
