Description

Technical Field

[0001] This utility model relates to the field of switching valve technology, and in particular to a valve body with a split assembly. Background Technology

[0002] A switching valve (or switching on / off valve) is a device used to control the direction of fluid flow and is widely used in various industrial and mechanical systems. Its main function is to switch between different operating modes by changing the path of the fluid flow. These valves are typically used in systems that require switching between multiple operating states, such as hydraulic systems, pneumatic systems, and fluid transport systems.

[0003] Existing switching valve technologies mostly use sealing rings and complex connection structures for sealing. However, this method cannot effectively prevent liquid leakage or loosening of connections, leading to frequent maintenance problems during use. For example, Chinese patent discloses "a valve body with a split assembly", with application number "CN202323065327.0". It uses a base, a clamping structure, and a locking device to achieve a detachable connection between the valve head and the actuator. When the connecting part of the base is clamped by the clamping structure, the valve core shaft of the valve head is connected to the drive shaft in the actuator. When the user needs to disassemble, simply loosen the locking device to release the clamping structure from the connection, and the valve head can be removed for replacement. During installation, insert the valve core shaft of the valve head onto the drive shaft, and then drive the clamping structure to clamp the connection of the base through the locking device. However, the installation and adjustment of the clamping structure and locking device require additional steps, which may increase the difficulty of operation for the user. When replacing the valve head, the locking device must be loosened first to release the clamping structure from the connection before the valve head can be removed and replaced. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art by providing a split-assembly valve body. Through a guide arc plate inserted between the first and second rubber gaskets, the rubber gaskets are tightly fitted to the base, significantly improving the sealing effect and preventing liquid leakage. Simultaneously, the locking rod and spring work together to ensure the stability and safety of the pipe connection, preventing loosening or shaking during use. This not only enhances the overall performance of the valve body but also improves the convenience of installation and maintenance.

[0005] This utility model also provides a valve body with the aforementioned split-assembly, comprising: a first pipe, a second pipe detachably connected to the other end of the first pipe, a valve head body disposed on the first pipe, a base fixedly connected to the side surface of the first pipe, a positioning rod fixedly connected to the outer surface of the base, and guide arc plates fixedly connected to both the positioning rod and the outer surface of the base; a fixing groove disposed inside the second pipe, a first rubber pad and a second rubber pad fixedly connected to both sides inside the fixing groove, a positioning block fixedly connected to the bottom of the fixing groove, and a locking rod disposed on the second pipe, with a spring and a connecting ring disposed on the locking rod. Through the above device, the cooperation of the rubber pads, guide arc plates, base, positioning rod, and positioning block, with the guide arc plate inserted between the first and second rubber pads, effectively improves the sealing performance at the connection, prevents liquid leakage, and enhances the stability of the assembly process.

[0006] According to the present invention, a split-assembly valve body is provided, in which a fixing plate is fixedly connected to the side surface of both the first pipe and the side surface of the second pipe, and the fixing plate is provided with mounting holes. This device, using the mounting holes of the fixing plate for fixation, enhances the connection stability between the first pipe and the second pipe.

[0007] According to the present invention, a split-assembly valve body has a circular base that fits snugly into a fixing groove. This device, through the design of the circular base, achieves a precise fit between the base and the fixing groove, ensuring assembly accuracy.

[0008] According to the present invention, a valve body with a split assembly includes an L-shaped positioning rod with a slot that passes through the positioning rod and the second pipe. This device, through the slot design of the L-shaped positioning rod, further improves the positioning accuracy during assembly.

[0009] According to the present invention, in a split-assembly valve body, the flow guide arc plate is located on the outermost side and is in contact with the bottom of the fixing groove. This device, through the contact between the flow guide arc plate and the bottom of the fixing groove, enhances the effect of inserting the rubber gasket.

[0010] According to the present invention, in a split-assembly valve body, the fixing groove has the same shape as the positioning rod and the base, and the positioning rod is clearance-fitted with the positioning block. Through this device, the consistent shape design allows the fixing groove to better fit with the positioning rod and the base, ensuring structural stability.

[0011] According to the present invention, a split-assembly valve body is provided, wherein the locking rod passes through the locking groove, and a sleeve is fixedly connected to the side surface of the second pipe, with the locking rod passing through the sleeve. Through this device, the through-hole structure of the locking rod and the sleeve further enhances the robustness of the connection between the first and second pipes.

[0012] According to the present invention, a split-assembly valve body includes a pull ring on the outside of the locking rod, a connecting ring fixedly connected to the side surface of the pull ring, and a spring fixedly connected to the connecting ring. This device, through the combination of the locking rod, pull ring, connecting ring, and spring, ensures that the pipe connection cannot loosen, thus increasing safety.

[0013] Beneficial effects

[0014] Compared to existing technologies, this valve body for split-assembly utilizes a guide arc plate inserted between the first and second rubber gaskets to ensure a tight seal between the rubber gaskets and the base, significantly improving the sealing effect and preventing liquid leakage. Simultaneously, the locking rod and spring work together to ensure the stability and safety of the pipe connection, preventing loosening or shaking during use. This not only enhances the overall performance of the valve body but also improves the ease of installation and maintenance. Attached Figure Description

The slot 8 has a clearance fit, and a positioning rod 6 is fixedly connected to the outer surface of the base 5. The positioning rod 6 ensures the accurate position of each component during assembly. The positioning rod 6 is L-shaped and has a slot 12. The slot 12 fixes the pipe and prevents the connection from loosening. The slot 12 passes through the positioning rod 6 and the second pipe 2. Both the positioning rod 6 and the outer surface of the base 5 are fixedly connected to a flow guide arc plate 7. The flow guide arc plate 7 enhances the insertion effect and fits against the bottom of the fixing slot 8 to ensure sealing. The flow guide arc plate 7 is located on the outermost side and fits against the bottom of the inner side of the fixing slot 8.

[0025] The second pipe 2 has a fixing groove 8 inside, which is the same shape as the positioning rod 6 and the base 5. The positioning rod 6 and the positioning block 11 are fitted with a clearance. The first rubber pad 9 and the second rubber pad 10 are fixedly connected to both sides inside the fixing groove 8. The first rubber pad 9 and the second rubber pad 10 provide a sealing function to prevent fluid leakage. The positioning block 11 is fixedly connected to the bottom inside the fixing groove 8 to enhance the structural stability. The second pipe 2 is provided with a clamping rod 14 to fix the pipe and prevent loosening. The clamping rod 14 passes through the clamping groove 12. The side surface of the second pipe 2 is fixedly connected with a sleeve 13. The clamping rod 14 passes through the sleeve 13.
