Description

Technical Field

[0001] This utility model relates to the field of valve technology, and more specifically, to a quick-installation three-way ball valve. Background Technology

[0002] Ball valves are a common fluid control component and are widely used in industrial pipeline systems.

[0003] Based on the above, the inventors have discovered that traditional ball valves are typically designed with one inlet and one outlet. For complex pipeline systems, the need for rapid connection and switching of multiple channels often cannot be met, resulting in poor overall applicability and inconvenience. Furthermore, in practical use, traditional ball valves lack effective limiting and indicating structures, making it difficult for operators to accurately judge the rotation angle of the ball and the opening / closing state of the valve, easily leading to misoperation. This, in turn, affects fluid transport efficiency and system safety, impacting the normal operation of the entire pipeline system. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a quick-installation three-way ball valve, aiming to achieve greater practical value.

At the same time, by setting a limit structure and an opening indicator, it can accurately display the rotation angle of the ball and the opening and closing status of the valve, avoiding the reduction of fluid transportation efficiency and system safety hazards caused by operator misjudgment, and ensuring the stable operation of the pipeline system.

[0006] 2. Technical Solution

A fixing plug is fitted on the outer periphery of the round stem section and is threaded to the inner wall of the valve seat. A lower limit stop is snapped onto the outer periphery of the round stem section. The lower limit stop is located at the bottom of the fixing plug. The bottom end of the valve stem extends into the valve cavity of the valve body and engages and is fixed with the top of the ball.

[0009] Furthermore, a conveying channel is provided on the outer periphery of the sphere, and the two ends of the conveying channel are respectively connected to the corresponding installation ports.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This solution, by setting up three installation ports and equipping them with quick-connect couplings, enables rapid connection and switching of multiple passages in complex piping systems, effectively improving the flexibility and efficiency of pipeline assembly. Simultaneously, the cooperation of the upper limit baffle and the limit block strictly limits the rotation angle of the valve stem, preventing passage misalignment caused by excessive ball rotation; the lower limit baffle constrains the axial movement of the valve stem, preventing it from falling off or shifting during operation. The combined design of the opening indicator and the opening observation hole allows operators to intuitively and accurately grasp the real-time opening and closing status of the valve, greatly reducing the probability of misoperation and further enhancing the safety and stability of system operation.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of 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.

[0041] Example:

[0042] Please see Figures 1-6A quick-installation three-way ball valve includes a valve body 1, a valve cavity 2 inside the valve body 1, a ball 3 movably installed in the valve cavity 2, three installation ports 4 connected to the valve cavity 2 on the outer periphery of the valve body 1, quick connectors 5 sealingly connected to the openings of the installation ports 4, a valve seat 6 integrally formed on the top of the valve body 1, a valve stem 7 provided in the valve seat 6, the valve stem 7 is composed of a square stem section, a round stem section and a snap-fit ​​section, an opening indicator disc 8 and an upper limit stop plate 9 are sleeved on the outer periphery of the square stem section of the valve stem 7, a fixing plug 10 is sleeved on the outer periphery of the round stem section of the valve stem 7 and the fixing plug 10 is threaded to the inner wall of the valve seat 6, a lower limit stop plate 11 is snapped on the outer periphery of the round stem section of the valve stem 7, the lower limit stop plate 11 is located at the bottom of the fixing plug 10, and the bottom end of the valve stem 7 extends into the valve cavity 2 of the valve body 1 and is snapped and fixed with the top of the ball 3.

[0043] See Figure 2 The outer periphery of the sphere 3 is provided with a conveying channel 13, and the two ends of the conveying channel 13 are respectively connected to the corresponding installation ports 4.

[0044] See Figure 2 and Figure 6 The outer periphery of the ball 3 is sealed to the inner wall of the valve cavity 2, and the bottom of the ball 3 is rotatably connected to the bottom of the valve cavity 2 by a pin.

[0045] See Figure 5 The top of the valve seat 6 has a groove, and two mutually symmetrical limit blocks 14 are fixedly connected to the side wall of the groove. The outer periphery of the upper limit baffle 9 is provided with an outward protrusion, and the outward protrusion is located between the two limit blocks 14. In use, by setting the upper limit baffle 9 and cooperating with the limit blocks 14 on the valve seat 6, the rotation angle of the valve stem 7 can be limited to ensure that the ball 3 is accurately positioned and to avoid excessive rotation that could cause misalignment of the passage.

[0046] See Figure 2 The opening indicator 8 is located between the upper limit baffle 9 and the fixed screw plug 10. The valve seat 6 has an opening observation hole 15 on its outer periphery, and the opening observation hole 15 corresponds to the position of the opening indicator 8.

[0047] See Figure 2 The lower limit baffle 11 consists of two crescent-shaped limit baffles. The outer circumference of the round rod section of the valve stem 7 is provided with an annular groove, and the crescent-shaped limit baffle is engaged in the annular groove. In use, the lower limit baffle 11, together with the fixing screw plug 10, can effectively prevent the valve stem 7 from moving axially and ensure the stability of the connection between the valve stem 7 and the ball 3.

[0048] See Figure 2The outer circumference of the round section of the valve stem 7 is equipped with an O-ring seal 12. The valve stem 7 is sealed to the inner wall of the valve seat 6 through the O-ring seal 12. During use, the O-ring seal 12 further enhances the sealing performance between the valve stem 7 and the valve seat 6, effectively preventing fluid leakage during transportation and improving the overall sealing reliability of the valve.

[0049] Working Principle: During use, the three mounting ports 4 of the valve body 1 can be quickly connected to external pipelines via the quick connector 5, meeting the need for rapid switching of multiple passages in complex pipeline systems. When it is necessary to adjust the fluid flow direction, the operator rotates the valve stem 7, which drives the ball 3 to rotate within the valve cavity 2. The delivery channel 13 on the outer periphery of the ball 3 then switches to the connected state of different mounting ports 4. During this process, the outer protrusion of the upper limit baffle 9 rotates between the two limit blocks 14, limiting the rotation angle of the valve stem 7, ensuring accurate positioning of the ball 3, and avoiding excessive rotation that could lead to misalignment of the passages. The lower limit baffle 11 cooperates with the fixing plug 10 to effectively prevent axial movement of the valve stem 7, ensuring the stability of the connection between the valve stem 7 and the ball 3. At the same time, the opening indicator 8 on the square section of the valve stem 7 rotates synchronously with the valve stem 7. The operator can visually read the scale on the indicator 8 through the opening observation hole 15 on the outer periphery of the valve seat 6, accurately judging the opening and closing state of the valve and the rotation angle of the ball 3, thereby precisely controlling the fluid delivery and significantly improving the ease of operation and the safety of system operation.
