Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and specifically relates to a sealing ball valve. Background Technology

[0002] Ball valves are a common type of valve in industrial production and daily life. The closing element is a ball, which rotates around the valve body's centerline to open and close the valve. They offer advantages such as low fluid resistance, simple structure, small size, light weight, high reliability, and ease of operation, making them widely used. A ball valve typically consists of a valve body, a ball, a stem, and a handle. During operation, the handle is held to rotate the ball, thus opening and closing the valve.

[0003] When existing ball valves are in operation, the handle is turned to drive the ball valve to rotate. However, since the ball valve is in the pipeline, the direction and angle of rotation of the ball valve cannot be clearly seen by turning the handle. This can easily lead to the valve being opened or closed accidentally, causing safety accidents and affecting the safe use of the ball valve. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a sealing ball valve with an anti-accidental contact function.

[0005] The objective of this utility model can be achieved through the following technical solution: A sealing ball valve includes a valve body, a valve ball disposed within the valve body, a valve stem connected to the valve ball, and the valve stem extending outside the valve body and connected to a handle switch. The valve stem is characterized by having a movable part, a fixed part on the valve body, and a positioning component for positioning the movable part on the fixed part. The movable part has a positioning hole that mates with the positioning component. The positioning component consists of a positioning element, a sliding part, a retaining ring, and a return spring. The valve body has a first mounting groove for installing the positioning component. One end of the positioning element engages with the positioning hole on the movable part, and the other end extends out of the valve body. The fixed part has a stop element, and a second mounting groove for installing the stop element. The stop element retracts and moves within the second mounting groove, and the valve ball is positioned by the action of the stop element and the positioning component.

[0006] In the aforementioned sealing ball valve, a connecting spring is provided in the mounting groove 2, the abutment abuts against the side end or lower end of the retaining ring, and the other end of the abutment extends out of the fixing part and is connected to a pull rod.

[0007] In the aforementioned type of sealing ball valve, when the positioning assembly does not position the movable part, the movable part moves within the valve body as the valve ball rotates.

[0008] In the aforementioned type of sealing ball valve, the sliding part slides up and down within the mounting groove.

[0009] In the aforementioned type of sealing ball valve, there are two positioning components, which are respectively located on the left and right sides of the valve body.

[0010] Compared with existing technologies, this sealed ball valve controls the positioning or movement of the valve ball through a positioning component and abutment, preventing the valve from being opened due to accidental contact by the operator. Attached Figure Description

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 As shown, this sealing ball valve includes a valve body 1, a valve ball 2 disposed inside the valve body 1, a valve stem 3 connected to the valve ball 2, and the valve stem 3 extending outside the valve body 1 and connected to a handle switch 4. The valve stem 3 has a movable part 14, and the valve body 1 has a fixed part 5. The fixed part 5 has a positioning component 6 for positioning the movable part 14. The movable part 14 has a positioning hole that mates with the positioning component 6. The positioning component 6 consists of a positioning element 7, a sliding part 8, and a... The valve body 1 is composed of a retaining ring 9 and a return spring 10. The valve body 1 has an installation groove 1 for installing the positioning component 6. One end of the positioning component 7 fits into the positioning hole on the movable part 14, and the other end of the positioning component 7 extends out of the valve body 1. The fixed part 5 is provided with a backing component 11. The fixed part 5 has an installation groove 2 for installing the backing component 11. The backing component 11 retracts and moves within the installation groove 2. Through the action of the backing component 11 and the positioning component 6, the valve ball 2 is positioned.

[0016] To elaborate further, a connecting spring 12 is provided in the mounting groove 2, and the abutment 11 abuts against the side end or the lower end of the retaining ring 9. The other end of the abutment 11 extends out of the fixing part 5 and is connected to a pull rod 13.

[0017] To elaborate further, when the valve ball 2 is fixed, the positioning member 7 in the positioning assembly 6 extends into the opening of the movable part 14 to position the movable part 14. At the same time, the abutment member 11 retracts into the second mounting groove, and the connecting spring 12 in the second mounting groove is in a compressed state. When the valve ball 2 does not need to be fixed, by pulling the positioning member 7 that extends out of the valve body 1, the return spring 10 in the first mounting groove is compressed, the positioning member 7 retracts into the first mounting groove, the retaining ring 9 moves upward, the connecting spring 12 in the second mounting groove rebounds, the abutment member 11 extends out of the second mounting groove, and the upper end of the abutment member 11 is in contact with the lower end of the retaining ring 9 to prevent the positioning member 7 from returning to its original position. The movable part 14 loses the positioning of the positioning assembly 6, and the valve ball 2 can rotate. When re-fixing is required, pulling the lever 13 retracts the abutment 11 into the mounting groove, the return spring 10 rebounds, and the positioning member 7 re-engages with the positioning hole of the movable part 14, preventing the valve ball 2 from rotating. This provides the present invention with an anti-accidental activation effect.

[0018] To elaborate further, when the positioning component 6 does not position the movable part 14, the movable part 14 moves within the valve body 1 as the valve ball 2 rotates.

[0019] To elaborate further, the sliding part 8 slides up and down within the mounting groove.

[0020] To elaborate further, there are two positioning components 6, which are respectively located on the left and right sides of the valve body 1.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0022] Although this document frequently uses terms such as valve body 1, valve ball 2, valve stem 3, handle switch 4, fixing part 5, positioning assembly 6, positioning element 7, sliding part 8, retaining ring 9, return spring 10, abutment 11, connecting spring 12, pull rod 13, and moving part 14, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
