Description

Technical Field

[0001] The present application relates to the technical field of ball valves, and more particularly to a sanitary ball valve with easy component replacement. Background Art

[0002] Sanitary ball valves are ball valves that can meet the special requirements of various media in the food and biopharmaceutical fields. They are mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control.

[0003] A search of existing publicly available technology reveals a sanitary ball valve with application number CN200520132037.6. The valve cover and valve body are symmetrically arranged in a hemispherical shape, with the sealing packing smoothly connected to the valve cover and valve body, leaving no dead angles. This makes it easy to clean. Furthermore, a bracket is mounted on the outer surface of the rotating shaft, which is fixed to the valve stem. The bracket has a lever positioning hole that mates with the lever, allowing the ball valve to be positioned correctly between open, half-open, and closed positions, providing excellent reliability.

[0004] However, the ball valve needs to be opened and closed frequently during the use of the valve. During the rotation of the ball, a small amount of medium enters the gap formed by the valve body, the ball and the seal, causing retained fluid to breed bacteria, which harms the quality of the products produced. In addition, when the valve cover is tightened, it will rub against the ball, which can easily cause wear to the ball and reduce the sealing performance. After leakage, the entire ball can only be replaced, and it is inconvenient to disassemble and assemble, which affects the user experience. The overall use effect is not very good.

[0005] In order to solve the above problems, the present application provides a sanitary ball valve that is easy to replace parts. Utility Model Content

[0006] The present application provides a sanitary ball valve that is easy to replace parts and adopts the following technical solution:

[0007] A sanitary ball valve with easy component replacement includes a valve body and a ball. The valve body is composed of a first base body and a second base body, and several groups of fastening blocks are welded around the surface of the first base body and the second base body. First bolts are installed between the fastening blocks. Installation grooves are provided on the surface of one side of the top of the first base body and the second base body. A sealing disk is clamped between the installation grooves. The sealing disk and the valve body are fixed by a second bolt. A fixing seat is welded at the top of the sealing disk. A shaft body is rotatably connected to the middle position of the fixing seat, and the two ends of the shaft body are respectively connected to the handle and the ball.

[0008] Through the above technical solution, the ball is the basic structure of the sanitary ball valve, so it will not be described in detail.

[0009] Furthermore, friction pads are connected to the inner surface of the first base body and the inner surface of the second base body via third bolts.

[0010] Through the above technical solution, the friction pad is set to contact the ball. On the one hand, it is to improve the sealing effect between the ball and the inside of the valve body when it is installed to prevent the medium from overflowing from the gap. On the other hand, it can prevent the ball from directly wearing out the structure on the outside of the valve body. In this way, only the friction pad needs to be replaced in the event of subsequent wear. Compared with replacing the entire valve body structure, the loss is smaller and it can be used better.

[0011] Furthermore, a connecting pipe is welded to one end of the first base body and one end of the second base body, and a flange is installed at one end of the connecting pipe.

[0012] Through the above technical solution, the flange is provided to facilitate the connection of the sanitary ball valve with external pipelines, thereby realizing the medium transportation operation.

[0013] Furthermore, a docking strip is installed around the surface of one end of the first base body.

[0014] Through the above technical solution, the docking strip is provided to cooperate with the docking groove, so that the sealing effect is better when the first basic block and the second basic block are connected, thereby ensuring the subsequent use quality.

[0015] Furthermore, a docking groove is formed around the surface of one end of the second base body.

[0016] Through the above technical solution, the docking groove is set to cooperate with the docking strip, thereby improving the sealing effect when the first basic block and the second basic block are connected. At the same time, the installation position can be limited to ensure the accuracy of the installation.

[0017] Furthermore, a positioning hole for installing a second bolt is opened on the surface of the installation groove.

[0018] Through the above technical solution, the positioning hole is provided to facilitate the connection and installation of the second bolt, and the positioning hole is provided with a thread inside, which can further enhance the stability of the bolt connection.

[0019] Furthermore, the joints of the valve body are filled with sealing gaskets.

[0020] Through the above technical solution, filling the sealing gasket at the joint can effectively improve the sealing of the entire structure and prevent the internal liquid from overflowing.

[0021] In summary, this application has the following beneficial technical effects:

[0022] This application adopts a first base body, a second base body and a sealing disc. When constructing the sanitary ball valve, the assembly operation of the entire structure can be achieved by inserting the sealing disc into the installation groove on the surface of the first base body and the second base body and fixing it with a second bolt. Moreover, since the structure is of a detachable type, it can be flexibly disassembled and maintained in the event of damage or failure, thereby reducing the operating difficulty of personnel and improving the flexibility of use of the device. At the same time, when damage occurs, only the corresponding components need to be replaced, and the entire structure does not need to be replaced simultaneously, which can reduce maintenance damage and reduce financial expenditure. It has the advantages of convenient maintenance, low wear and replacement loss, and flexible use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example:

[0033] The present application discloses a sanitary ball valve that is easy to replace parts. Figure 1-4 , including a valve body 1 and a ball 18, the valve body 1 is composed of a first base body 2 and a second base body 3, and several groups of fastening blocks 4 are welded around the surface positions of the first base body 2 and the second base body 3, and first bolts 5 are installed between the fastening blocks 4. The first base body 2 and the second base body 3 are provided with mounting grooves 11 on the surface positions on one side of the top, and a sealing disk 17 is clamped between the mounting grooves 11. The sealing disk 17 and the valve body 1 are fixed by a second bolt 8. A fixing seat 9 is welded on the top position of the sealing disk 17, and a shaft body is rotatably connected to the middle position of the fixing seat 9, and the two ends of the shaft body are respectively connected to the handle 10 and the ball 18. The ball 18 is the basic structure of the sanitary ball valve, so it will not be described in detail.

[0034] See also Figure 1 and Figure 4 The inner surface of the first base body 2 and the inner surface of the second base body 3 are both connected with a friction pad 14 through a third bolt 15. The friction pad 14 is set to contact the ball 18. On the one hand, it is to improve the sealing effect between the ball 18 and the inside of the valve body 1 when it is installed to prevent the medium from overflowing from the gap. On the other hand, it can prevent the ball 18 from directly wearing out with the structure on the outside of the valve body 1. In this way, when it is subsequently worn, you only need to replace the friction pad 14. Compared with replacing the entire valve body 1 structure, the loss is smaller and it can be used better.

[0035] See also Figure 1-3The friction pad 14 is set to contact the ball 18. On the one hand, it is to improve the sealing effect between the ball 18 and the inside of the valve body 1 when it is installed to prevent the medium from overflowing from the gap. On the other hand, it can prevent the ball 18 from directly wearing out the structure on the outside of the valve body 1. In this way, only the friction pad 14 needs to be replaced in the event of subsequent wear. Compared with replacing the entire valve body 1 structure, the loss is smaller and it can be used better. The flange 7 is set to facilitate the connection of the sanitary ball valve with the external pipeline, thereby realizing the medium transportation operation.

[0036] See also Figure 1 and Figure 3 A docking strip 16 is installed around the surface of one end of the first basic body 2. The docking strip 16 is provided to cooperate with the docking groove 13 to achieve a better sealing effect when the first basic block and the second basic block are connected, thereby ensuring the quality of subsequent use.

[0037] See also Figure 1 and Figure 2 A docking groove 13 is provided around the surface of one end of the second base body 3. The docking groove 13 is provided to cooperate with the docking strip 16 to improve the sealing effect when the first base block and the second base block are connected. At the same time, the installation position can be limited to ensure the accuracy of the installation.

[0038] See also Figure 1-3 A positioning hole 12 for installing the second bolt 8 is opened on the surface of the mounting groove 11. The positioning hole 12 is provided to facilitate the connection and installation of the second bolt 8, and a thread is provided inside the positioning hole 12, which can further enhance the stability of the bolt connection.

[0039] See also Figure 1 The joints of the valve body 1 are filled with sealing gaskets. Filling the joints with sealing gaskets can effectively improve the sealing of the entire structure and prevent the internal liquid from overflowing.

[0040] The implementation principle of this embodiment is: when in use, personnel can insert the sealing disk 17 into the installation grooves 11 on both sides in turn, and then the connection operation between the first base body 2 and the second base body 3 and the ball 18 can be realized, thereby forming a complete sanitary ball valve. Subsequently, the flanges 7 on both sides of the valve body 1 are connected to the external pipeline to realize normal conveying operation. Moreover, since the entire sanitary ball valve is composed of multiple detachable parts, when damage occurs, only the corresponding damaged parts need to be replaced, and the entire ball valve does not need to be replaced, which effectively reduces the loss during maintenance. Moreover, when the ball 18 is severely worn, the ball 18 and the friction pad 14 can be replaced, so that the first base body 2 and the second base body 3 do not need to be replaced, which can further reduce the overall loss and improve the use effect of the device. At the same time, the detachable structure also makes the entire maintenance operation more convenient and quick. The device as a whole has the advantages of easy maintenance, low wear and replacement loss, and flexible use.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
