Technical Field
[0001] The utility model relates to the technical field of ball valves, in particular to a high-temperature V-type ball valve for a lithium battery anode material coating granulation reactor. Background Technique
[0002] As an adjustable ball valve, the V-type ball valve is widely used in the control of fluids such as slurries, powders, granules, and mud, and is generally used in working conditions above medium temperature. However, with the rise of the lithium battery anode material industry, more and more high-temperature reactors use V-type ball valves. Generally, ball valves are prone to blockage at the exhaust port of high-temperature reactors, unable to achieve tight shut-off, and jamming phenomena will also occur. The current V-type ball valves can no longer meet the use requirements of new working conditions, so it is necessary to develop a new type of high-temperature V-type ball valve. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is: to solve the problems that general ball valves are prone to blockage at the exhaust port of high-temperature reactors, unable to achieve tight shut-off, and jamming phenomena will also occur, and the current V-type ball valves can no longer meet the use requirements of new working conditions. Now, a high-temperature V-type ball valve for a lithium battery anode material coating granulation reactor is provided.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a high-temperature V-type ball valve for a lithium battery anode material coating granulation reactor, including a valve body and a valve seat and a ball core arranged in the valve body. A valve rod is arranged on the valve body, and one end of the valve rod is arranged on the ball core. The valve body is also provided with a chute matching the valve seat, and the valve seat is arranged in the chute. One end of the valve seat contacts the ball core to form a sealing surface, and a compensation groove with elastic deformation ability is arranged on the sealing surface. A sealing component for ensuring the seal between the valve seat and the valve body is arranged in the chute, and an elastic component for providing a pre-tightening force for the valve seat is arranged in the chute. The sealing component is located between the elastic component and the valve seat. Compared with the prior art, in this solution, the elastic component provides a pre-tightening force for the valve seat. Since the sealing component is located between the elastic component and the valve seat, the elastic component always presses the sealing component against the valve seat to ensure the sealing performance of the valve seat. During the opening and closing process of the ball core, under the extrusion of the ball core and in cooperation with the compensation groove on the sealing surface, the valve seat has a certain displacement space and the elastic component will deform. On the one hand, it can effectively provide an elastic pre-tightening force for the valve seat, and on the other hand, the reserved space of the valve seat prevents the ball core from jamming with the valve seat.
[0005] In order to implement the sealing component, in some preferred embodiments, the sealing component is a sealing ring, the material of the sealing ring is graphite carbon fiber, and a notch matching the sealing ring is arranged at one end of the valve seat away from the ball core, and the sealing ring is arranged in the notch.
[0006] In order to ensure stable and reliable sealing between the valve body and the valve seat, in some preferred embodiments, the contact surface between the valve seat and the sealing ring is an inclined surface. By having an inclined surface between the sealing ring and the valve seat, the inclined surface has a certain guiding effect to ensure strict sealing between the valve seat and the valve body.
[0007] In some preferred embodiments, the inclined surface is arranged to gradually incline upward from the inside to the outside in the radial direction of the valve seat.
[0008] In some preferred embodiments, one end of the elastic component abuts against the sealing ring through a pressing ring.
[0009] In some preferred embodiments, the elastic component is a disc spring.
[0010] In some preferred embodiments, an adjusting mechanism for the pre-tightening force of the elastic component is arranged on the valve body.
[0011] In order to implement the submission mechanism, in some preferred embodiments, the adjusting mechanism includes a retaining ring which is threadedly connected to the valve body, and the elastic component is arranged between the valve seat and the retaining ring. By means of the retaining ring threadedly connected to the valve body, the sealing specific pressure can be adjusted at any time according to the contact situation between the valve seat and the ball core, so as to achieve a tight cut-off between the ball core and the valve seat.
[0012] In order to ensure stable and reliable operation of the valve, in some preferred embodiments, one side of the ball core relative to the valve stem is rotatably installed on the valve body through a secondary shaft, and a collar is arranged between the valve body and the secondary shaft, and the material of the collar is graphite. By arranging a collar between the valve body and the secondary shaft and the material of the collar is graphite, it can prevent ash powder medium from entering and ensure long-term low-load operation of the valve.
[0013] Since the ball valve is applied in a high-temperature environment, in order to reduce the influence of high-temperature medium on the packing component, in some preferred embodiments, an upper valve cover is arranged on the valve body, one end of the valve stem passes through the upper valve cover, and heat dissipation fins are arranged on the outer peripheral surface of the upper valve cover. Through the lengthened design of the upper valve cover and the design of heat dissipation fins on the outer peripheral surface of the upper valve cover, the high temperature of the medium is gradually reduced, so that the packing component is not affected by high temperature.
[0014] The beneficial effects of the present utility model are as follows: When the high-temperature V-type ball valve for the coating granulation reactor of the negative electrode material of the lithium battery of the present utility model is in use, a pre-tightening force is provided for the valve seat through the elastic component. Since the sealing component is located between the elastic component and the valve seat, the elastic component always presses the sealing component against the valve seat to ensure the sealing performance of the valve seat. During the opening and closing process of the ball core, under the extrusion of the ball core and in cooperation with the supplementary groove on the sealing surface, the valve seat has a certain displacement space and the elastic component will deform. On the one hand, it can effectively provide an elastic pre-tightening force for the valve seat. On the other hand, the reserved space of the valve seat prevents the ball core from being stuck with the valve seat, avoiding the problems that the general ball valve is prone to blockage at the exhaust port of the high-temperature reactor, unable to achieve tight shut-off, and there will also be a stuck phenomenon, and the current V-ball valve can no longer meet the use requirements of the new working conditions.

[0024] As Figures 1-3 shown, a high-temperature V-type ball valve for a granulation reactor with coated lithium battery anode material includes a valve body 11, a valve seat 1 and a ball core 2 arranged inside the valve body 11. A valve rod 3 is arranged on the valve body 11. One end of the valve rod 3 is arranged on the ball core 2. The valve body 11 is also provided with a chute 4 matching the valve seat 1. The valve seat 1 is arranged in the chute 4 provided. One end of the valve seat 1 contacts the ball core 2 to form a sealing surface. A compensation groove 8 with elastic deformation ability is arranged on the sealing surface. A sealing component 5 for ensuring the seal between the valve seat 1 and the valve body 11 is arranged in the chute 4. An elastic component 6 for providing a pre-tightening force for the valve seat 1 is arranged in the chute 4. The sealing component 5 is located between the elastic component 6 and the valve seat 1.
[0025] In order to achieve high-temperature and strict cut-off, the valve seat 1 component adopts a high-temperature and high-performance sealing structure. The spherical surface of the ball core 2 and the sealing surface of the valve seat 1 are sprayed with chromium carbide, which is wear-resistant and high-temperature resistant, and ground to a mirror-level finish to achieve zero gas leakage.
[0026] The sealing component 5 is a sealing ring, and the material of the sealing ring is graphite carbon fiber. A notch matching the sealing ring is provided at one end of the valve seat 1 away from the ball core 2, and the sealing ring is arranged in the notch. The contact surface between the valve seat 1 and the sealing ring is an inclined surface, which is inclined upward gradually from the inside to the outside in the radial direction of the valve seat 1.
[0027] One end of the elastic component 6 is abutted against the sealing ring 8 through a pressing ring, and the elastic component 6 is a disc spring.
[0028] An adjusting mechanism for the pre-tightening force of the elastic component 6 is arranged on the valve body 11. The adjusting mechanism includes a retaining ring 7, and the retaining ring 7 is threadedly connected to the valve body 11. The elastic component 6 is arranged between the valve seat 1 and the retaining ring 7.
[0029] One side of the ball core 2 relative to the valve rod 3 is rotatably installed on the valve body 11 through a secondary shaft 12. A collar 13 is arranged between the valve body 11 and the secondary shaft 12. The material of the collar 13 is graphite. An upper valve cover 9 is arranged on the valve body 11. One end of the valve rod 3 passes through the upper valve cover 9, and heat dissipation fins 10 are arranged on the outer peripheral surface of the upper valve cover 9.
[0030] When the above-mentioned high-temperature V-type ball valve for a lithium battery anode material coating granulation reactor is in use, the valve rod 3 drives the ball core to rotate in the valve body 11, and makes the ball core contact or separate from the valve seat 1, realizing the opening or closing of the ball valve. During this process, when the ball core 2 contacts the valve seat 1, it will receive an extrusion effect. At this time, the valve seat 1 will displace in the chute 4 and squeeze the disc spring, and the disc spring deforms, ensuring that the ball core 2 and the valve seat 1 will not be stuck. At the same time, the disc spring always exerts a force on the sealing component 5, ensuring that the sealing component 5 always seals stably and reliably between the valve seat 1 and the valve body 11. And with the contact surface between the sealing component 5 and the valve seat 1 being an inclined surface, the sealing performance between the valve seat 1 and the valve body 11 is improved. At the same time, the supplementary groove 8 also has a certain elastic deformation ability. When the valve seat 1 contacts the ball core 2, the supplementary groove 8 is squeezed, preventing the ball core 2 and the valve seat 1 from being stuck.
[0031] Based on the inspiration of the ideal embodiments of the present invention described above, through the above description, relevant workers can completely make various changes and modifications within the scope not deviating from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
