Its characteristics include compact structure, good sealing performance, high reliability, long service life, etc. The following will introduce the structure, working principle, characteristics and application of stainless steel compression sleeve needle valve in detail.
The stainless steel compression needle valve is mainly composed of valve body, valve stem, ferrule and sealing ring. The inside of the valve body is usually provided with a channel connected to the pipe, and the opening and closing state of the valve is controlled by the up and down movement of the valve stem. The ferrule is used to fix the position of the sealing ring to ensure that the valve has good sealing performance.
The working principle of stainless steel compression sleeve needle valve is mainly to use the up and down movement of the valve stem to control the opening and closing state of the valve. When the valve is closed, the stem is in close contact with the seal, which prevents the flow of the medium. When the valve is opened, the stem separates from the seal and the medium can flow through the valve. Due to the presence of the ferrule, the position of the sealing ring is well fixed, avoiding seal failure due to media erosion.
Stainless steel compression type needle valve has the following features:
1.Compact structure: The valve is small in size, simple in structure, easy to install and maintain.
2.Good sealing performance: the soft and hard double sealing structure is adopted, which can ensure the sealing performance of the valve.
3.High reliability: Due to the simple structure of the valve and few moving parts, it has high reliability.
4.Long service life: Since the valve material is made of stainless steel, it has strong corrosion resistance, so it has a long service life.
Stainless steel compression type needle valves are widely used in the following fields:
1.Oil: It is used to control the circulation of oil products in oil pipelines.
2.Chemical: It is used to control the circulation of chemical substances in chemical pipelines.
3.Medicine: It is used to control the circulation of drugs in pharmaceutical pipelines.
4.Other fields: such as food, electronics and other fields that require precise control of fluid media.
