Description

Technical Field

[0001] The utility model relates to the technical field of flow valves, in particular to a rust-proof and freeze-proof flow valve. Background Art

[0002] A flow valve is a device used to regulate the flow of a fluid medium. It can control the flow rate and flow rate of the fluid by adjusting the opening of the valve, thereby achieving regulation and control of the fluid medium. It is usually used in pipeline systems, industrial equipment and fluid control systems to ensure that the flow or pressure of the fluid medium in the pipeline or equipment is within a predetermined range.

[0003] In the prior art, a Chinese patent with authorization announcement number CN218440677U discloses a flow valve, including a shell, a support rod is fixedly connected to the inside of the shell, a folding plate is arranged above the support rod, a baffle is attached to the side of the folding plate away from the support rod, the baffle is arranged on the inner wall of the shell, and a trigger unit is arranged on the side of the folding plate away from the baffle. The flow valve, through the cooperation between the support rod, the folding plate, the baffle, the screw slider and the screw, realizes that the fluid flows through the folding plate in two streams, and then the two streams of fluid blend together, which can offset the impact force to a certain extent, and the flow velocity is monitored after the integration inside the shell, which solves the problem that the internal fluid of the traditional flow valve impacts the inside of the flow valve, which is not conducive to the flow monitoring of the internal measurement and control device of the flow valve. The fluid of the flow valve is more stable, so the monitoring is more accurate and the flow stabilization effect is good.

[0004] The above device controls the opening and closing of the valve by rotating the flip plate, but in actual use, the valve is generally made of metal material, which is greatly affected by thermal expansion and contraction. Therefore, when used in a low temperature environment, metal contraction may cause the gap between parts to become larger and affect use. Utility Model Content

[0032] When using the device, first use the mounting flange 2 to install the valve housing 1 in the pipeline. When the valve needs to be opened or closed, the staff operates the rotating handle 7. The rotating handle 7 drives the rotating shaft 6 to rotate under the limiting action of the limit block 18, so that the rotating shaft 6 drives the butterfly valve plate 3 to rotate, thereby realizing the opening and closing of the valve.
