Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts technology, and more specifically, it relates to a three-piece high-platform ball valve that is easy to install. Background Technology

[0002] When connecting water pipes, a switch is needed to control the water flow. A three-piece high-platform ball valve is required to control the water flow. The three-piece valve consists of a valve body and two valve covers locked together by four extended bolts to form a three-section structure. During maintenance and disassembly, the pipeline does not need to be disassembled. The valve body or the inside of the water pipe can be inspected and maintained, making it convenient to use.

[0003] According to CN202120493816.8, this utility model discloses a high-platform three-piece ball valve, including a valve body and valve covers on both sides of the valve body. A ball is located inside the valve body, and a valve stem is connected to the top of the ball. A stuffing box is provided between the valve body and the valve stem. The stuffing box includes a packing assembly and a packing sleeve. The packing sleeve is located at the upper end of the packing assembly, and a butterfly spring is also provided at the upper end of the packing sleeve. A clamping nut is provided at the upper end of the butterfly spring. The handle is connected to the valve stem via a nut. In this utility model, a clamping nut is added to the upper end of the butterfly spring, adding a clamping force to the pre-tightening force of the clamping nut on the stuffing box, improving the sealing performance of the valve stem. A full-enclosure sealing ring is provided between the ball and the valve cover, effectively preventing leakage by completely enclosing the ball within the sealing ring, greatly improving the valve's sealing performance.

[0004] Based on the above, existing three-piece high-platform ball valves are generally installed by inserting bolts into the sockets. When connecting the valve body to the two valve covers, the operator needs to align the sockets on the valve body and valve covers one by one, and then insert the long bolts into the sockets, which makes the installation and alignment of the valve body and valve covers quite cumbersome.
