Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a ball valve that is easy to assemble. Background Technology

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, with their V-shaped ball core and hard alloy-faced metal seat, possess strong shearing force, making them particularly suitable for media containing fibers or small solid particles. Multi-port ball valves not only flexibly control the merging, splitting, and switching of flow directions in pipelines, but also allow the closure of any channel while connecting the other two.

[0003] Traditional ball valves present many inconveniences during installation, especially when connecting the ball valve to the pipes on both sides. This often requires complex installation techniques and tools. On the one hand, the design of the connection between the pipe and the ball valve is not reasonable enough, which may lead to difficulty in alignment during installation, requiring a lot of time for adjustment and seriously affecting installation efficiency.

[0004] On the other hand, after long-term use, the disassembly and installation of the rotating disc at the top of the valve is cumbersome and requires the removal of a large number of related parts. This not only increases maintenance time and cost, but may also cause long-term interference with the normal operation of the entire pipeline system.

[0005] Therefore, we propose a ball valve that is easy to assemble. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, and the following technical solution is adopted:

[0007] A ball valve that is easy to assemble includes a ball valve pipeline, on both sides of the ball valve pipeline there are positioning grooves, on both sides of the ball valve pipeline there are first connecting flanges, at the connection of the two positioning grooves there are sealing positioning blocks, at the connection of the two sealing positioning blocks there are main pipelines, and on the inner side of the two main pipelines there are second connecting flanges.

[0008] The ball valve pipeline is also equipped with a connecting block. The connecting block has a rotating rod at its connection point. The connecting block is equipped with a quick-release assembly. The quick-release assembly includes two mounting cavities. Each of the two mounting cavities is equipped with several compression springs. Each of the compression springs has a connecting plate at its connection point. Each of the two connecting plates is equipped with a limit plug rod. Each of the two limit plug rods has an arc-shaped pressing head at its connection point.

[0011] As a preferred embodiment of this utility model, an installation pipe is installed at the top of the ball valve pipeline, the installation pipe is interconnected with the ball valve pipeline, a rotating rod is installed at the top of the installation pipe, and two through grooves are formed on the rotating rod.

[0012] As a preferred embodiment of this utility model, a ball valve body is installed at the bottom of the rotating rod, and a rotating disk is installed at the top of the connecting block, with the connecting block and the rotating disk being fixed to each other.

[0013] As a preferred embodiment of this utility model, the quick disassembly assembly further includes several limiting slide grooves, each of which is formed on the side walls of the two mounting cavities. Each of the limiting slide grooves is slidably connected to a limiting slider. An mounting plate is installed between multiple adjacent limiting sliders. The limiting plug rod passes through the mounting plate, and the mounting plate and the connecting plate are connected to each other. The limiting plug rod and the mounting plate are fixed to each other.

[0014] As a preferred embodiment of this utility model, the limiting plug rod is inserted into the two through slots of the rotating rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the connection structure between the ball valve and the pipes on both sides is optimized, making it more convenient to assemble the pipes with the ball valve.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to relevant references, and several embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] Example

[0027] like Figure 1-5As shown, this utility model provides a technical solution: Positioning grooves 2 are provided on both sides of the ball valve pipe 1. This is one of the key designs for convenient assembly. The positioning grooves 2 provide an accurate positioning reference for the subsequent connection of the main pipe 4. The first connecting flanges 3 installed on both sides of the ball valve pipe 1 are important components for connecting with the main pipe 4. A sealing positioning block 5 is provided at the connection point of the two positioning grooves 2. Its material has good sealing and wear resistance. The main pipe 4 is inserted into the positioning grooves 2 of the ball valve pipe 1 through the sealing positioning block 5. This design utilizes the cooperation between the sealing positioning block 5 and the positioning groove 2. The shape of the sealing positioning block 5 is precisely aligned with the positioning groove 2. When the main pipe 4 is inserted, the sealing positioning block 5 guides the main pipe 4 to accurately enter the positioning groove 2. At the same time, its own sealing performance can prevent the medium from leaking at the connection. Moreover, the second connecting flange 6 of the main pipe 4 and the first connecting flange 3 of the ball valve pipe 1 are connected and fixed by several sealing bolts 7. The sealing bolts 7 can not only provide sufficient connection force to ensure the firmness of the pipe connection, but also further enhance the sealing performance of the connection with the design of the sealing gasket, etc., to prevent the medium from leaking. This combination of positioning groove 2, sealing positioning block 5 and flange bolt connection greatly optimizes the connection structure.

[0028] First, align the main pipe 4 with the positioning grooves 2 on both sides of the ball valve pipe 1, so that the sealing positioning block 5 inside the main pipe 4 is inserted into the positioning groove 2. During the insertion process, the main pipe 4 can automatically align itself due to the matching shape of the sealing positioning block 5 and the positioning groove 2. Then, align the second connecting flange 6 of the main pipe 4 with the first connecting flange 3 of the ball valve pipe 1, insert the sealing bolt 7 and tighten it to complete the connection between the ball valve and the main pipes 4 on both sides.

[0029] A connecting block 11 is installed inside the ball valve pipeline 1. A rotating rod 9 is provided at the connection point of the connecting block 11. A quick-release assembly is installed inside the connecting block 11. The quick-release assembly includes two mounting cavities 13, which provide installation space for other internal components. Several compression springs 20 are installed inside each of the two mounting cavities 13. The compression springs 20 are one of the core components for realizing the quick-release function. A connecting plate 17 is installed at the connection point of the compression springs 20. When subjected to external force, the compression springs 20 can drive the connecting plate 17 to move through their own elastic deformation. Limiting plug rods 18 are installed on both connecting plates 17. The limiting plug rods 18 are used for connection and fixation with the rotating rod 9. An arc-shaped pressing head 19 is provided at the connection point of the two limiting plug rods 18. The arc-shaped pressing head 19 facilitates the operator to apply external force. In addition, the quick-release assembly also includes several limiting grooves 14. Several limiting grooves 14 are formed on the side walls of the two mounting cavities 13. Limiting sliders 15 are slidably connected to the limiting grooves 14. Mounting plates 16 are installed between multiple adjacent limiting sliders 15. Limiting plug rods 18 pass through the mounting plates 16 and connect to the connecting plates 17. The limiting plug rods 18 and the mounting plates 16 are fixed to each other. This design makes the limiting plug rods 18 more stable during movement. When it is necessary to disassemble the rotating disk 12, press the arc-shaped pressing head 19. The arc-shaped pressing head 19 transmits external force to the limiting plug rods 18, so that the limiting plug rods 18 overcome the elastic force of the compression spring 20 and are pulled out from the through groove of the rotating rod 9. Thus, the rotating disk 12 can be disassembled. When installing the rotating disk 12, after the rotating disk 12 is installed in place, release the arc-shaped pressing head 19. The elastic force of the compression spring 20 will push the limiting plug rods 18 into the through groove of the rotating rod 9 to achieve quick fixation.

[0030] During disassembly, press the arc-shaped pressing head 19 to allow the limiting plug rod 18 to move into the mounting cavity 13 under the guidance of the limiting slide groove 14 and the limiting slider 15, overcoming the elastic force of the compression spring 20, until the limiting plug rod 18 is completely pulled out of the through groove of the rotating rod 9. Then the rotating disk 12 can be removed. During installation, place the rotating disk 12 in a suitable position so that the through groove on the rotating rod 9 is aligned with the limiting plug rod 18. Release the arc-shaped pressing head 19, and the compression spring 20 will push the limiting plug rod 18 into the through groove, completing the installation of the rotating disk 12.

[0031] This easy-to-assemble ball valve achieves convenient assembly and rapid maintenance by optimizing the connection structure between the ball valve and the pipelines on both sides and designing a quick-disassembly component for the rotating disc 12 on the top of the valve. When installing the ball valve, it can quickly and accurately connect the ball valve to the pipelines on both sides, reducing installation time and difficulty. In case of failure of the rotating disc 12, it can be quickly disassembled and replaced, improving the maintenance efficiency of the equipment and ensuring the stable operation of the entire pipeline system.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
