Description

Technical Field

[0001] This utility model relates to the field of valves, and in particular to a butterfly valve that can be quickly disassembled online for end applications. Background Technology

[0002] Butterfly valves are widely used components in piping systems. A commonly used butterfly valve structure can be seen in patent publication CN116518091A. Because butterfly valves need to connect pipes on both sides, flange connections are provided at both ends. However, when used at the end of a piping system, one of the flange structures needs to be removed. In the butterfly valve structure disclosed in patent publication CN116518091A, the flange is installed on the valve body via a threaded connection. This threaded connection not only has poor installation reliability but also makes removal difficult and prone to causing valve body vibration. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a butterfly valve that can be quickly disassembled online for end-use applications. The first or second flange plate can be removed by tightening the first or second bolt, and once the first or second flange plate is removed, it can be used in the pipeline end system.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A butterfly valve for online quick-release end application includes a valve body, a valve plate, a valve seat, and a handle. The valve seat is disposed within the valve body, the valve plate is rotatably disposed within the valve body, and the handle is rotatably disposed on the valve body, with the valve plate and the handle engaging together. The valve body also includes a first flange plate and a second flange plate. The first flange plate is detachably engaged with the valve body via a first bolt, and the second flange plate is detachably engaged with the valve body via a second bolt. The first bolt and the second bolt do not contact each other.

[0006] In this type of butterfly valve, a first flange plate and a second flange plate are respectively installed on both sides of the valve body by a first bolt and a second bolt. When used in a non-end-of-pipeline system, the first flange plate and the second flange plate can be connected and matched with the pipelines on both sides. When it needs to be used in the end-of-pipeline system, only one flange plate is needed. Therefore, it is only necessary to remove the first bolt or the second bolt. After removing the first bolt or the second bolt, the first flange plate or the second flange plate can be removed. After removing the first flange plate or the second flange plate, it can be used in the end-of-pipeline system.

[0007] In summary, in this type of butterfly valve, the first flange plate or the second flange plate can be removed simply by turning the first bolt or the second bolt. Once the first flange plate or the second flange plate is removed, it can be used in the pipeline terminal system.

[0008] Meanwhile, in this type of butterfly valve, the first flange plate and the second flange plate are fixed with bolts. Therefore, the first flange plate and the second flange plate are essentially clamped and fixed at both ends of the valve body. This clamping and fixing installation method is more convenient and stable than threaded installation.

[0009] Optionally, the valve body is provided with a screw, and a first nut sleeve and a second nut sleeve are respectively provided at both ends of the screw. The first bolt is engaged with the first nut sleeve, and the second bolt is engaged with the second nut sleeve.

[0010] Specifically, the screw passes through the valve body, and a first nut sleeve and a second nut sleeve are respectively installed at both ends of the screw. The first nut sleeve and the second nut sleeve clamp and abut against the valve body from both sides.

[0011] Optionally, the valve body includes a first plate and a second plate, the first plate and the second plate being engaged together by the screw, and the valve seat being located between the first plate and the second plate.

[0012] Specifically, the screw passes through the valve body, the first nut sleeve abuts against the first plate, and the second nut sleeve abuts against the second plate. The first nut sleeve and the second nut sleeve together clamp the first plate and the second plate.

[0013] Optionally, the first plate is a cylindrical first plate, and the second plate is a cylindrical second plate.

[0014] Optionally, the first flange plate and the second flange plate have the same shape and size, and the first bolt and the second bolt have the same shape and size.

[0015] The first flange plate and the second flange plate are the same in shape and size, and the first bolt and the second bolt are the same in shape and size. This makes the structure on both sides the same, so both sides can be used and there is no distinction between the front and back sides.

[0016] Optionally, a sealing ring is provided between the first flange plate and the valve body, and a sealing ring is provided between the second flange plate and the valve body.

[0017] The sealing ring serves to seal between the valve body and the flange plate. Specifically, the sealing ring is installed between the first flange plate and the first plate body, and the sealing ring is installed between the second flange plate and the second plate body.

[0018] Optionally, it also includes a sleeve, which is disposed on the valve body and located outside the valve body, and the handle is rotatably engaged with the sleeve.

[0019] The sleeve is clamped onto the first plate and the second plate, and the sleeve plays a certain role in clamping the first plate and the second plate.

[0020] Optionally, the first flange plate and the second flange plate are located on both sides of the sleeve, and the first bolt and the second bolt are located on both sides of the sleeve.

[0021] The beneficial effects of this utility model are: the first flange plate or the second flange plate can be removed by simply turning the first bolt or the second bolt, and once the first flange plate or the second flange plate is removed, it can be applied to the pipeline end system.
