Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a hard-seal metal ball valve. Background Technology

[0002] Metal hard-seal ball valves, as components used to control the on / off state and flow rate of pipeline systems, have been widely used in many fields such as petroleum, chemical, metallurgy, and hydropower.

[0003] Ball valves have a simple structure, are easy to operate, open and close quickly, have low fluid resistance, and good sealing performance. They can usually withstand high-pressure and high-temperature working environments. The ball of the ball valve can realize various flow control modes such as fully open and fully closed regulation. Therefore, they are widely used in the flow control and cut-off of various media, making them play an important role in application. Therefore, timely installation and disassembly are required.

[0004] According to the utility model patent with Chinese patent application number 202021730032, a double-channel metal hard-seal ball valve is proposed. This double-channel metal hard-seal ball valve can solve the problem that conventional metal hard-seal ball valves cannot guarantee a seal after damage to the single sealing surface in fluid media containing hard particles and in working conditions requiring a tight seal. However, this double-channel metal hard-seal ball valve does not have a docking structure. When the ball valve is damaged and replaced, rust may occur at the connection between the pipeline and the ball valve. In order to facilitate the disassembly of the ball valve, the joint end of the pipeline needs to be cut off, which damages the pipeline and makes the disassembly of the ball valve complicated and time-consuming. Therefore, it is necessary to propose a hard-seal metal ball valve to solve the above-mentioned problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a hard-seal metal ball valve, which has the advantages of convenient docking, installation, and disassembly of the ball valve, thus solving the problem that ball valves in the prior art do not have docking functionality.

[0006] To achieve the above-mentioned purpose of facilitating the docking, installation, and disassembly of the ball valve, this utility model provides the following technical solution: a hard-seal metal ball valve, including a ball valve body, a first connecting pipe and a second connecting pipe respectively provided on the left and right sides of the ball valve body, a fixed disc fixedly installed on the opposite side of the first connecting pipe and the second connecting pipe, and a docking assembly movably installed inside the fixed disc;

[0007] The docking assembly includes a rotating cylinder, which is movably mounted inside the fixed disk. A connecting pipe is threaded inside the rotating cylinder, and a rotating ring is movably mounted outside the fixed disk. A first sealing ring is provided at the end of the connecting pipe.

[0008] Furthermore, a second sealing ring is provided at the end of the rotating drum, and the rotating drum passes through the fixed disc and extends into the interior of the first connecting pipe.

[0009] Furthermore, a positioning component is installed on the outside of the rotating ring. The positioning component includes a fixing block. The fixing block is fixedly installed on the outside of the rotating ring, and a positioning rod is threadedly connected to the inside of the fixing block.

[0010] Furthermore, a knob is connected to the end of the positioning rod, and multiple positioning slots are formed on the outside of the fixed disc, into which the positioning rod is inserted.

[0011] Furthermore, a through groove is provided on the outside of the fixed disc, and a connecting rod passes through the inside of the through groove.

[0012] Furthermore, a connecting rod is fixedly connected to the inner wall of the rotating ring, a rotating cylinder is fixedly connected to the bottom of the connecting rod, and an adjusting disc is movably installed on the top of the ball valve body.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This hard-seal metal ball valve, through the installation of a docking assembly, allows for easy installation by connecting the connecting pipe to one side of the pipeline. The pipeline then limits the position of the connecting pipe. By rotating the rotating ring, the rotating ring, via the connecting rod, drives the rotating cylinder to rotate inside the fixed disc, causing the connecting pipe to be threaded into the inside of the rotating cylinder. The connecting pipe then gradually extends in length until it is fully extended into the pipeline. Repeating the above steps connects and fixes both ends of the first and second connecting pipes to the pipeline, thus enabling rapid installation of the ball valve body. The operation is simple and convenient.

[0015] This hard-seal metal ball valve features a positioning component. During use, after the ball valve body is installed via the docking assembly, rotating the knob drives the positioning rod to rotate. The positioning rod is threaded into the fixing block, allowing it to extend downwards into the positioning groove. The positioning groove and positioning component position and limit the rotating ring, preventing the ball valve body from becoming loose due to the rotating ring's rotation, which could affect the valve's performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment, a hard-seal metal ball valve includes a ball valve body 1. A first connecting pipe 3 and a second connecting pipe 4 are respectively provided on the left and right sides of the ball valve body 1. A fixed disc 5 is fixedly installed on the side of the first connecting pipe 3 and the second connecting pipe 4 that are opposite to each other. A docking assembly 8 is movably installed inside the fixed disc 5.

[0023] The docking assembly 8 includes a rotating cylinder 801, which is movably mounted inside the fixed disk 5. A connecting pipe 802 is threadedly connected inside the rotating cylinder 801. A rotating ring 804 is movably mounted outside the fixed disk 5. A first sealing ring 803 is provided at the end of the connecting pipe 802.

[0024] In the case implementation, by setting up a connecting pipe 802, the connecting pipe 802 is connected to one side of the pipeline, and the connecting pipe 802 is limited by the pipeline.

[0025] In the implementation of the case, by rotating the rotating ring 804, the rotating ring 804 will drive the rotating cylinder 801 to rotate inside the fixed disc 5 through the connecting rod 11, so that the connecting pipe 802 is threadedly connected to the inside of the rotating cylinder 801. The connecting pipe 802 will gradually extend in length until it is completely extended into the inside of the pipe. The above steps are repeated to connect and fix the two ends of the first connecting pipe 3 and the second connecting pipe 4 to the pipe, thereby realizing the quick installation of the ball valve body 1. The operation steps are simple and convenient for operation and installation.

[0026] In the implementation of the case, by setting the positioning component 7, when the ball valve body 1 is installed through the docking component 8, the positioning rod 702 is rotated by rotating the knob 703. The positioning rod 702 is threaded into the fixing block 701, so that the positioning rod 702 extends downward into the positioning groove 6. The positioning groove 6 and the positioning component 7 position and limit the rotating ring 804, so as to prevent the rotation of the rotating ring 804 from causing the installation of the ball valve body 1 to become loose and affecting the use effect.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, connect the connector 802 to the pipeline so that the pipeline limits the movement of the connector 802;

[0029] 2) Then, the first connecting pipe 3 and the second connecting pipe 4 are connected and fixed to the pipeline by the docking component 8;

[0030] 3) The swivel ring 804 is then locked and limited by the positioning component 7;

[0031] 4) Finally, adjust the ball valve body 1 using the adjusting disc 2.

[0032] In summary, this hard-seal metal ball valve, by setting the docking assembly 8, allows the docking pipe 802 to be docked to one side of the pipeline during use. The pipeline limits the docking pipe 802, and by rotating the rotating ring 804, the rotating ring 804 drives the rotating cylinder 801 to rotate inside the fixed disc 5 via the connecting rod 11. This causes the docking pipe 802 to be threaded into the inside of the rotating cylinder 801, and the docking pipe 802 gradually extends in length until it is completely extended into the inside of the pipeline. Repeating the above steps connects and fixes both ends of the first connecting pipe 3 and the second connecting pipe 4 to the pipeline, thereby achieving quick installation of the ball valve body 1. The operation steps are simple and convenient for installation.

[0033] Furthermore, by setting the positioning component 7, when the ball valve body 1 is installed through the docking component 8, the positioning rod 702 is rotated by rotating the knob 703. The positioning rod 702 is threaded into the fixing block 701, thereby causing the positioning rod 702 to extend downward into the positioning groove 6. The positioning groove 6 and the positioning component 7 position and limit the rotating ring 804, preventing the rotation of the rotating ring 804 from causing the installation of the ball valve body 1 to become loose and affecting the use effect.
