Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to a stop valve with a quick-disassembly structure. Background Art

[0002] The stop valve has a simpler structure than the gate valve, and is easier to manufacture and maintain. The sealing surface is not easily worn or scratched, and has good sealing performance. There is no relative sliding between the valve disc and the sealing surface of the valve body during opening and closing, so the wear and scratches are not serious. The sealing performance is good and the service life is long. When opening and closing, the valve disc has a small stroke, so the stop valve is smaller in height than the gate valve, but the structural length is longer than the gate valve, the opening and closing torque is large, the opening and closing is more laborious, the opening and closing time is longer, and the fluid resistance is large. Because the medium channel in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.

[0003] When using the stop valve, it is often necessary to disassemble, maintain and replace it. However, most traditional low-temperature stop valves are fixed with many bolts when connected to other pipelines, which will make it extremely time-consuming and labor-intensive to disassemble them later, which is extremely inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide a stop valve with a quick-release structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stop valve with a quick-release structure, comprising a stop valve body, interface pipes are provided on both sides of the stop valve body, a first flange is provided on one side of the two interface pipes, a threaded groove is provided on one side of the two first flanges, a second flange is provided on one side of the two first flanges, a threaded ring is provided on one side of the two second flanges, an external tube is provided on one side of the two second flanges, a card groove is provided around one side of the first flange, connecting columns are provided around the outer rings of the two external tubes, and the inner cavities of the connecting columns are threadedly connected to support rods.

[0006] Preferably, the first flange and the second flange are of the same size.
