Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, in particular to a wafer-type butterfly valve which is easy to disassemble and repair. Background Art

[0002] The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0°-90°. When it rotates to 90°, the valve is fully open. This valve is generally installed horizontally. The wafer butterfly valve has a simple structure, small size, and light weight. It is composed of only a few parts, and it can be quickly opened and closed by rotating 90°. The operation is simple. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, so it has good flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valves, the sealing ring can be embedded in the valve body or attached to the periphery of the butterfly plate.

[0003] After searching, the Chinese patent publication number CN219035724U discloses a clamp-type electric butterfly valve, including a valve body, a fixing frame and a transmission valve stem, the fixing frame is detachably connected to the upper surface of the valve body, the transmission valve stem is connected to the inside of the fixing frame, and the end extends to the inside of the valve body, the transmission valve stem is composed of a rod body, a clamping hole and a clamping groove, the clamping hole is opened on the upper end of the rod body surface, and the rod body has multiple clamping holes, and the clamping groove is opened at the top of the rod body. When in use, there are two driving modes: manual and electric. When the power is off, the use effect of the valve body will not be affected, which effectively meets the use requirements, and it is also convenient to install and disassemble the driver, which is convenient for later replacement and maintenance.

[0004] The above patent has the following disadvantages: the staff cannot remove the butterfly plate quickly and conveniently, which consumes a lot of manpower and material resources, affects work efficiency, and may cause the entire wafer butterfly valve to be unusable. In view of this, we propose a wafer butterfly valve that is easy to disassemble and repair. Utility Model Content
