Description

Technical Field

[0001] The utility model relates to the technical field of cock valve installation, and more specifically, to a cock that is convenient for installation. Background Technique

[0002] A cock valve is a valve that realizes opening or closing by rotating a plug so that the channel opening on the plug communicates with or separates from the channel opening on the valve body. The shape of the plug can be cylindrical or conical. The channel of a cylindrical plug is generally rectangular, and the channel of a conical plug is trapezoidal.

[0003] When installing the existing cock valve, there is a lack of a corresponding positioning structure, which affects the docking efficiency between the top cover and the cock valve. In the prior art CN220622800U, by setting a docking component, the quick docking of the top cover and the lower connecting plate is realized. The positioning block is inserted into the positioning groove of the lower connecting plate to realize the docking positioning of the top cover and the lower connecting plate. The four threaded insertion shafts synchronously penetrate through the through holes of the lower connecting plate and the top cover, and the nut is sleeved on the surface of the threaded insertion shaft for locking and fixing, thus ensuring the docking efficiency between the top cover and the lower connecting plate. However, this structure is prone to wear between the indicating ring and the upper connecting plate during installation. When wear occurs between the indicating ring and the connecting rod, the rotation angle is inconvenient to observe. In view of this, we propose a cock that is convenient for installation.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment:

[0025] Please refer to Figures 1-4 , a plug that is convenient for installation, including a valve body 1. A plug body 2 is arranged inside the valve body 1. An adjusting rod 3 is arranged at the upper end of the plug body 2. The adjusting rod 3 is used to rotate the plug body 2 to realize the connection and closing of the pipelines at both ends of the valve body 1. An indicator ring 4 is installed on the adjusting rod 3. The indicator ring 4 is fixedly connected to the adjusting rod 3 as a whole. A connecting plate A5 is arranged on the valve body 1. A connecting plate B6 is arranged on the plug body 2. The connecting plate A5 and the connecting plate B6 are connected by bolts;

[0026] A rotating ring 7 is sleeved in the middle of the connecting plate B6. The rotating ring 7 is rotatably connected to the connecting plate B6. A groove 701 is opened on the outer wall of the rotating ring 7. The cross-section of the rotating ring 7 presents an I-shaped structure due to the opening of the groove 701. Among them, the adjusting rod 3 passes through the rotating ring 7 and is movably connected to the rotating ring 7. A through hole is opened in the middle of the connecting plate B6. The rotating ring 7 is rotatably installed in the through hole. A convex ring 601 is arranged in the through hole. A cavity is formed between the convex ring 601 and the inner side wall of the groove 701. A limiting component 8 is arranged on the indicator ring 4. The limiting component 8 passes through the rotating ring 7 and extends into the cavity. A positioning block 9 is arranged in the cavity. The limiting component 8 can contact the positioning block 9. Through the arrangement of the limiting component 8, the indicator ring 4 is fixedly connected to the rotating ring 7. When the plug body 2 is rotated, the indicator ring 4 and the rotating ring 7 rotate along with it, so as to facilitate observing the rotation angle.

[0027] In this application, the limiting component 8 includes two relatively arranged insert blocks 801. The insert blocks 801 are installed on the bottom surface of the indicator ring 4. A connection hole is opened on the rotating ring 7. The insert blocks 801 pass through the connection hole and extend into the groove 701. The insert blocks 801 are clamped with the positioning block 9. Through the cooperation of the insert blocks 801 and the connection hole, the position of the indicator ring 4 relative to the rotating ring 7 in the circumferential direction is limited. As Figure 4 shown, the connection hole is located at a position above one side of the groove 701 of the rotating ring 7, so that the bottom surface of the insert block 801 can contact the inner wall of the bottom of the groove 701.

[0028] In this application, an installation cavity 802 is formed inside the insertion block 801. The inner side of the installation cavity 802 can communicate with the groove 701. A push rod 803 is movably connected inside the installation cavity 802. The upper end of the push rod 803 extends above the indicating ring 4. The push rod 803 is movably connected to the indicating ring 4 and the insertion block 801. Among them, a connecting rod 805 is rotatably connected inside the installation cavity 802. The push block 806 can contact the connecting rod 805. Torsion springs 807 are arranged at both ends of the connecting rod 805. One end of the torsion spring 807 is connected to the connecting rod 805, and the other end of the torsion spring 807 is connected to the inner wall of the installation cavity 802. An installation shaft is arranged through the middle of the connecting rod 805, and the torsion spring 807 is sleeved on the installation shaft. When the plug body 2 is disassembled through the setting of the torsion spring 807, the push rod 803 is moved upward. Under the action of the elastic force, the torsion spring 807 drives the connecting rod 805 to reset, so that the connecting rod 805 enters the installation cavity 802, thus facilitating the disassembly of the plug body 2. By moving the push rod 803 downward, the push rod 803 is used to push the connecting rod 805 to tilt toward the positioning block 9, so that the end of the connecting rod 805 contacts the bottom surface of the positioning block 9, thereby restricting the position of the indicating ring 4 in the vertical direction.

[0029] In a possible embodiment, a spring is arranged at the bottom of the insertion block 801. When the end of the connecting rod 805 is located on the bottom surface of the positioning block 9, the spring is in a compressed state. The restoring elastic force of the spring is used to provide an upward thrust, so that the end of the connecting rod 805 is in close contact with the bottom surface of the positioning block 9.

[0030] In this application, the push rod 803 can also be set as a threaded rod, and the threaded rod is rotatably connected to the indicating ring 4. A push block 806 is arranged inside the installation cavity 802. The push block 806 is of an inverted conical structure. The threaded rod is threadedly connected to the push block 806. A slide rod 804 is arranged through one side of the push block 806. The slide rod 804 is slidably matched with the push block 806. Through the setting of the slide rod 804, the moving track of the push block 806 is restricted. When the threaded rod rotates, the push block 806 threadedly connected to the threaded rod will move in the vertical direction. Since the push block 806 is of an inverted conical structure, when the push block 806 moves downward, it will push the connecting rod 805 to rotate outward around the connecting axis at its lower end, so that the end of the connecting rod 805 is in close contact with the bottom surface of the positioning block 9, realizing the fixation between the indicating ring 4 and the connecting plate B6.

[0031] In this application, multiple groups of sealing rings 10 are arranged on the inner surface of the contact between the rotating ring 7 and the connecting plate B6. The setting of the group of sealing rings 10 realizes the sealing between the rotating ring 7 and the connecting plate B6.

[0032] In this application, a sealing chassis 101 is arranged at the bottom of the valve body 1. The sealing chassis 101 is hermetically connected to the valve body 1 and is in sealing contact with the plug body 2. When the plug body 2 is installed into the valve body 1, the plug body 2 is in sealing contact with the sealing chassis 101.

[0033] Working principle: When installing the cock body 2, pass the cock body 2 through the rotating ring 7 and place it inside the valve body 1. During this process, align the insertion block 801 with the connection hole on the rotating ring 7, insert the insertion block 801 into the groove 701, and then rotate the push rod 803, i.e., the threaded rod, so that the push block 806 threadedly connected to the threaded rod moves in the vertical direction. Since the push block 806 has an inverted conical structure, when the push block 806 moves downward, it will push the connecting rod 805 to rotate outward around the connection axis at its lower end, so that the end of the connecting rod 805 is in close contact with the bottom surface of the positioning block 9, realizing the fixation between the indicating ring 4 and the connecting plate B6. Then connect the connecting plate A5 and the connecting plate B6 with bolts to achieve the connection between the cock body 2 and the valve body 1. And when the cock body 2 is rotated, the indicating ring 4 will also rotate accordingly. Through the setting of the limiting component 8, the indicating ring 4 is connected and fixed to the rotating ring 7. When the cock body 2 is rotated, even if the indicating ring 4 is worn, it will not affect the observation of the rotation angle of the cock body 2.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
