Stainless steel globe valve material introduction and characteristics
Release Time:2020-08-28  Browse: times
Stainless steel globe valve is a kind of globe valve. The detailed stainless steel raw materials are CF8 (304), CF3 (304L), CF8M (316), CF3M (316L). Different raw materials are used, which can be applied to water, steam, and oil. , Nitric acid, acetic acid, oxidizing media, urea and other media.

Stainless steel globe valves are divided into manual stainless steel globe valves, pneumatic stainless steel globe valves, and electric stainless steel globe valves. Connection methods include general shut-off valve threaded stainless steel shut-off valve, angle stainless steel shut-off valve, three-way stainless steel shut-off valve, direct-flow stainless steel shut-off valve, insulation stainless steel shut-off valve, etc. The most significant advantage is: in the opening and closing process, Because the friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve, it is wear-resistant.

Stainless steel globe valve holding point:
The structure is simpler than the gate valve, and it is more convenient to manufacture and repair.
The sealing surface is not easy to wear and scratch, and the sealing performance is good. There is no relative sliding between the valve disc and the sealing surface of the valve body when opening and closing, so the wear and scratches are not serious, the sealing performance is good, and the service life is long.
When opening and closing, the disc stroke is small, so the height of the stop valve is smaller than that of the gate valve, but the structure length is longer than that of the gate valve.
The opening and closing moment is large, and the opening and closing is more laborious. The principal at the opening and closing time.
The fluid resistance is large, because the medium channel in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.
When the nominal pressure of the medium moving direction PN≤16MPa, the downstream flow is generally selected, and the medium flows upward from below the valve flap; when the nominal pressure PN≥20MPa, the reverse flow is generally selected, and the medium flows downward from the top of the valve flap. In order to increase the seal performance. When in use, the stop valve medium can only move in one direction and cannot change the direction of movement.
The disc is often eroded when fully opened.
As an indispensable part of the valve industry, the globe valve plays a pivotal role in the development of China's industry. From the beginning of the liberation of the stainless steel globe valve to today, the production and manufacturing model has been continuously improved, but facing the foreign WJ41H bellows Valves still have a long way to go. Foreign products are gaining ground in China's valve market. Because their products are indeed excellent, China's stainless steel globe valve industry is facing a serious market crisis. The crisis has greatly stimulated domestic globe valve manufacturers, prompting the formation of a kind of With a competitive competition model, companies need to step up their independent research and development, actively open up new markets, expand business channels, and lay a solid foundation for China's valve industry to go global
