Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve which is easy to clean. Background Art

[0002] Butterfly valve is a commonly used fluid control valve with simple structure and convenient operation. It is widely used in various industrial fields. The name of butterfly valve comes from the shape of the disc inside the valve body, which is similar to the wings of a butterfly. They usually consist of a round or oval valve body and a rotatable valve plate.

[0003] When butterfly valves are used on pipelines that transport industrial salt, they can control the transport of salt. However, due to the characteristics of industrial salt, a large amount of crystals will adhere to the internal structure of the butterfly valve over a long period of time, causing the butterfly valve to be blocked and difficult to open. Workers need to regularly disassemble the butterfly valve and clean the crystals inside the butterfly valve, and then install the butterfly valve on the pipeline that transports industrial salt. This series of operations is cumbersome. To this end, we propose a valve that is easy to clean. Utility Model Content

[0024] Working principle: when cleaning the crystals adhered to the internal structure of the valve body 1, first rotate the knob screw 13 outward until the knob screw 13 leaves a corresponding threaded hole 12 on the tube wall of the valve body 1, and then push the connecting ring 5 in the direction of the multiple L-shaped tubes 4, the connecting ring 5 can drive the multiple connecting rods 11 to rotate synchronously, the multiple connecting rods 11 can drive the respectively connected splicing rods 9 to slide upward in the corresponding slide grooves 6, the multiple splicing rods 9 can drive the respectively connected guide rods 7 to slide upward in the corresponding connecting plates 8, and the multiple splicing rods 9 can drive the respectively connected blocking covers 10 to move upward, and the multiple blocking covers 10 can drive the respectively connected blocking blocks 14 to leave the corresponding L-shaped tubes 4 until the multiple splicing rods 9 are in contact with the tops of the respectively corresponding slide grooves 6, at this time, the knob screw 13 will correspond to another threaded hole 12 on the tube wall of the valve body 1, at this time, tightening the knob screw 13 in the threaded hole 12 can fix the connecting ring 5, and the multiple blocking blocks 14 will also be suspended and fixed.
