Description

Technical Field

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

[0002] A ball valve is a type of valve that uses a ball as its opening and closing element, controlling the flow of fluid through the rotation of the ball. It features simple structure, good sealing performance, convenient operation, and high durability, and is widely used in industries such as petroleum, chemical, and water supply. Depending on their structure and function, ball valves can be classified into floating ball valves, fixed ball valves, three-way ball valves, etc., suitable for fluid control needs in various operating conditions.

[0003] In existing ball valves, the valve cover and valve body are sealed by vapor phase welding. However, this welding method has certain problems. During the production process, cutting debris, welding spatter, or other processing residues may adhere to the surface of the cover. If these residues are not completely cleaned, the high-temperature gas flow during vapor phase welding may blow them into the valve body, causing contamination of the sealing surface or valve core assembly, thereby affecting the valve's sealing performance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ball valve with reliable sealing. It adopts a snap-fit ​​structure instead of the traditional welding method, which avoids the sealing problems that may occur during the welding process and improves the reliability of the valve.

[0005] To solve the above-mentioned technical problems, this utility model provides a reliable sealing ball valve, including a pipe body and a valve body disposed on the pipe body. The valve body is provided with a valve core assembly, and the valve core assembly has a water passage groove that communicates with the pipe body. The valve body is provided with a valve cover assembly, which includes a snap-fit ​​post. The valve core assembly includes a slot, and the snap-fit ​​post is inserted into the slot. The valve cover assembly drives the valve core assembly to rotate to control the opening and closing of the water passage groove and the pipe body. A support ring is provided between the valve body and the valve cover assembly, and the valve cover assembly is mounted on the valve body through the support ring.

[0006] The valve cover assembly includes a valve cover body, on which a handle for driving its rotation is provided, a snap-fit ​​post is disposed at the center of the valve cover body, an outer side is provided on the outer side of the valve cover body, and an inner side is provided between the outer side and the snap-fit ​​post.

[0007] The valve core assembly includes a valve core body, a water passage groove disposed within the valve core body, a mounting portion provided on the valve core body, and a slot disposed within the mounting portion.

[0008] An inner mounting groove is provided between the inner side and the snap-fit ​​post, and the mounting part is inserted into the inner mounting groove. An outer mounting groove is provided between the outer side and the inner side, and the valve body and the support ring are inserted into the outer mounting groove.

[0009] The support ring is provided with a buckle, and the valve body is provided with a slot, and the buckle is engaged in the slot.

[0010] The mounting part is provided with a first step, and a sealing ring is provided on the first step. A gasket is also provided above the sealing ring.

[0011] The mounting part is also provided with a second step, which is located above the first step, and the inner side abuts against the second step.

[0012] The inner wall of the outer side is provided with a protruding ring, and the valve body is provided with a groove, and the protruding ring is engaged in the groove.

[0013] The valve body is provided with a limiting rib, and the outer side abuts against the limiting rib.

[0014] A limiting block is also provided on the outer side, and the limiting rib restricts the movement range of the limiting block.

[0015] During assembly, the valve core assembly is first placed into the valve body, and the support ring is installed on the valve body, ensuring that the snap-fit ​​is engaged in the slot. The sealing ring and gasket are then sequentially fitted onto the first step. Next, the snap-fit ​​post on the valve cover body is inserted into the slot of the mounting part, so that the mounting part is inserted into the inner mounting slot, and the valve body and support ring are inserted into the outer mounting slot. Simultaneously, the convex ring slides into the groove, completing the assembly. In use, the valve cover body is rotated via the handle to rotate the valve core assembly until the limiting block abuts against the limiting convex edge, thus connecting or disconnecting the water passage between the water channel and the pipe body.

[0016] The beneficial effects of this utility model are:

[0017] This invention uses a snap-fit ​​structure instead of the traditional welding method, avoiding potential sealing problems that may occur during the welding process.
