进口波纹管密封单座调节阀哪家品牌好

进口波纹管密封单座调节阀Product Description:

The utility model relates to the field of single seat regulating valves, including a valve body and a valve cover, the valve cover is fixedly connected to the valve body, the valve cover is slidably connected with a valve rod, the valve rod is fixedly connected with a valve core, the valve body is provided with a movable through groove, the valve body is provided with a flow channel cavity, the valve body is fixedly connected with a bellows, the valve rod enters the flow channel cavity through the bellows, the end of the bellows that is not connected to the valve body is fixedly connected to the valve core, and the bellows isolates the internal space between the flow channel cavity and the valve cover; The corrugated pipe includes an inner corrugated pipe and an outer corrugated pipe, and more than 5 partition rings are fixedly connected between the inner corrugated pipe and the outer corrugated pipe. The support of the partition ring reduces the friction between the inner corrugated pipe and the outer corrugated pipe. When the outer corrugated pipe is broken, the inner corrugated pipe can be blocked for the second time. The partition ring can divide the corrugated pipe into multiple sections. When a crack occurs in one section, it is not easy to extend to the next section of the corrugated pipe, reducing the replacement frequency of the corrugated pipe and reducing the replacement cost of the corrugated pipe.

进口波纹管密封单座调节阀characteristic:

Bellows sleeve regulating valve is a variant of sleeve regulating valve. Packing is used for external dynamic sealing of common control valves used in petrochemical, coal chemical, pharmaceutical, power station and other industrial departments. As the valve rod moves continuously, the packing is worn after long-term operation, and the medium may leak out. In order to achieve absolute sealing, the bellows sealed regulating valve is developed. The medium is sealed in the space between the valve body and the bonnet by the bellows element, and is isolated from the packing chamber of the dynamic seal. Therefore, there is no channel for external leakage.

进口波纹管密封单座调节阀Principle:

The valve cover is slidably connected with a valve rod, the valve rod is fixedly connected with a valve core, the valve body is provided with a movable through groove, the valve body is provided with a flow channel cavity, the valve rod penetrates into the flow channel cavity through the movable through groove, the valve body is fixedly connected with a bellows, the valve rod passes through the bellows, the end of the bellows that is not connected with the valve body is fixed

ly connected with the valve core, and the bellows isolates the internal space between the flow channel cavity and the valve cover;
