Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a valve connecting flange. Background Art

[0002] Flange, also known as flange flange or flange, is a part that connects shafts to each other and is used for connection between pipe ends. It is also used in flanges on equipment inlets and outlets for connection between two devices, such as reducer flanges. Flange connection or flange joint refers to a detachable connection consisting of flanges, gaskets and bolts that are connected to each other as a combined sealing structure. When water pumps and valves are connected to pipelines, parts of these equipment are also made into corresponding flange shapes, also known as flange connections. All connecting parts that are bolted and closed around two planes are generally called "flanges", such as the connection of ventilation ducts. This type of parts can be called "flange parts". A sealing ring is usually installed between the two flanges on the valve to achieve a sealing effect, and the two flanges are fixed by bolts.

[0003] However, although some valve connection flanges can be fixed by bolts, they do not have the effect of quick disassembly and assembly, which wastes a lot of manpower and time. At the same time, the bolts are prone to rust and damage after long-term use, resulting in gaps between the two flanges, which are prone to water leakage and air leakage, causing inconvenience to users. Therefore, we propose a valve connection flange to solve the above problems. Utility Model Content

[0011] Further preferably, two positioning rods are fixedly connected to one side of the two first flanges close to each other, and the vertical blocks are slidably sleeved on the outer sides of the corresponding positioning rods.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model holds the annular block and moves it to the side away from the valve body, so that the connecting rod drives the cross rod to move upward to stretch the spring, and the square rod is separated from the square groove. During installation, the second flange is moved to the side close to the valve body in the same way, and then the thrust on the annular block is released.
