Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve accessories, in particular to a butterfly plate of a high-performance butterfly valve with no tip connection. Background Art

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve that can be used for on-off control of low-pressure pipeline media. A butterfly valve is a valve with a disc as the closing member, which rotates around the valve shaft to open and close. A "tipless disc" refers to a disc without a pin or pin connection. This disc is usually connected to other components through other means to achieve the function of rotation or control movement. Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] However, most of the existing disc plates are solid. Due to the large mass of the disc plates, the overall energy consumption of the equipment is increased. Secondly, the disc plates have a smooth surface and do not have a flow-guiding function, which increases the flow resistance and eddy current and reduces the flow control accuracy. Therefore, a disc plate for a high-performance butterfly valve with no tip connection is proposed. Utility Model Content

A positioning rod 607 is fixed on the top of the guide plate 606, and the positioning rod 607 is adapted to the positioning hole 3. A connecting rod 608 is fixed on the outside of the guide plate 606, and one end of the connecting rod 608 passes through the through groove 604 and is fixed with a pull handle 609. The setting of the guide groove 2, the mounting frame 601 and the guide plate 602 can reduce flow resistance and eddy current, and improve the control accuracy of the equipment on the flow rate. By setting a spring 605, a guide plate 606, a positioning rod 607, a connecting rod 608 and a pull handle 609, the position of the positioning rod 607 can be adjusted by pulling the pull handle 609, so that it can be quickly inserted into and out of the positioning hole 3, thereby realizing rapid disassembly and assembly of the guide structure 6, and facilitating subsequent maintenance.

[0032] Working principle: Before being put into use, install the mounting frame 601 in the guide groove 2. First, pull the two sets of handles 609 on the mounting frame 601 in the direction of approaching each other at the same time. The handle 609 drives the connecting rod 608, and the connecting rod 608 drives the guide plate 606. The guide plate 606 drives the positioning rod 607 to retract into the storage hole 603. Then, place the mounting frame 601 in the guide groove 2, and then release the handle 609. Under the thrust of the spring 605, the positioning rod 607 is inserted into the positioning hole 3 to realize the installation of the guide structure 6.

The setting of the cavity 4 can reduce the weight of the equipment to achieve a lightweight design, reduce the operating torque and energy consumption of the equipment, and improve the operating performance of the valve. The design of the honeycomb structure 5 can improve the overall strength of the disc plate and prevent deformation in high-pressure or large-caliber applications.
