Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a ball core angle valve. Background Technology

[0002] In daily life, tap water has become commonplace in every household. In the home water system, the angle valve, as a throttling device used for pipe connection, is a key component for controlling water flow. Its performance directly affects the water usage experience. Due to structural issues, traditional angle valves are prone to leakage, clogging, and other problems. Therefore, people have improved angle valves by replacing them with ball valves. However, most ball valves on the market are still too complex in structure and inconvenient to install.

[0003] For the reasons mentioned above, it is necessary to improve the existing technology. Utility Model Content

Detailed Implementation

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Please see Figure 1-6This utility model provides a ball core angle valve, including a valve body 1, the valve body 1 having a hollow interior forming a receiving cavity 10, the valve body 1 having an installation hole 11 and a water inlet hole 12 respectively at both ends, the valve body 1 having a water outlet hole 13 on the side, the installation hole 11, the water inlet hole 12 and the water outlet hole 13 being connected through the receiving cavity 10, and a stop ring 120 being provided at the connection between the receiving cavity 10 and the water inlet hole 12;

[0026] Valve cover 2, the valve cover 2 is disposed on the mounting hole 11, and its end is provided with a valve stem hole 20 coaxially disposed with the water inlet hole 12;

[0027] The ball core 3 is rotatably disposed in the receiving cavity 10, and one end of the ball core 3 extends outward to form a valve stem 30. The valve stem 30 passes through the valve stem hole 20. The bottom periphery of the ball core 3 extends outward to form a flange portion 31 that abuts against the stop ring 120. The ball core 3 is inserted into the receiving cavity 10 through the mounting hole 11, and its top end is pressed against the end of the valve cover 2.

[0028] In the above structure, the mounting hole and the water inlet hole are respectively located on both sides of the valve body, and the axial positions of the two holes are the same. The water outlet hole is located on one side of the valve body. The mounting hole, the water inlet hole, and the water outlet hole are connected by a receiving cavity. When the ball valve needs to be assembled, the operator puts the ball core into the receiving cavity from the mounting hole, so that the flange at the bottom of the ball core presses against the stop ring set at the connection between the water inlet hole and the receiving cavity. The stop ring has a bottom limiting effect on the ball core. Then, the valve cover is set on the mounting hole, the valve stem of the ball core passes through the valve stem hole, and the valve cover fixes the ball core into the receiving cavity, so that its top is limited by the valve cover. The overall structure is simple and the installation and operation are convenient.

[0029] Specifically, the stop ring 120 is provided with symmetrically arranged stop blocks 121, and a limiting groove 122 is formed in the gap between the stop blocks 121. The bottom end of the ball core 3 is provided with a limiting block 32 that moves along the limiting groove 122. When the ball core rotates, it drives the limiting block at its bottom end to rotate synchronously. The limiting block rotates along the limiting groove until it is stopped by the stop block. The maximum rotation angle of the ball core is limited by the stop block, thereby ensuring the accuracy of the rotation angle of the ball core.

[0030] Specifically, the inner wall of the mounting hole 11 is provided with an internal thread 110, and one end of the valve cover 2 is provided with an external thread 21 that cooperates with the internal thread 110. The cooperation between the internal thread and the external thread makes the valve cover and the mounting hole threadedly connected, making the operation of installing the valve cover easier, and allowing for multiple installations and removals.

[0031] Specifically, the valve stem 30 has teeth 300 on its end ring. The teeth on the end ring of the valve stem can increase the friction, making it easier for the operator to rotate the ball core.

[0032] Specifically, two first sealing rings 301 are fitted at the gap between the valve stem 30 and the valve stem hole 20. The first sealing rings can increase the sealing between the valve stem and the valve stem hole.

[0033] Specifically, a tightening ring 130 is fixedly installed in the water outlet 13, and a second sealing ring 131 is sleeved on the top of the tightening ring 130 to press against the ball core 3. By inserting the tightening ring from the water outlet to the receiving cavity, the second sealing ring is simultaneously driven to press against the side of the ball core, thereby increasing the sealing performance of the connection between the ball core and the water outlet.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
