Fluorine-lined Ball Valve Manufacturers Share The Structural Characteristics Of Fluorine-lined Right-angle Stop Valves

Structural features of Lined Globe Valve

Fluorine-lined right-angle stop valve refers to a valve in which the closing part (valve disc) driven by the valve stem moves up and down along the center axis of the valve seat. It is mainly used to connect or cut off the medium in the pipeline. . It has the advantages of compact structure, flexible opening and closing, strong corrosion resistance, short stroke (generally 1/4 of the nominal diameter). It is suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, clear hydrofluoric acid and various organic acids, strong acids, and strong oxidants at -50℃ to 150℃. FEP is also suitable for pipelines of various concentrations of strong alkali organic solvents and other corrosive gases and liquid media.

Fluorine-lined right-angle stop valve product structure:

The shell of the fluorine-lined stop valve is made of investment casting, which has high strength and smooth appearance. . Valve body, valve cover, valve disc, etc. Excellent corrosion-resistant materials (fluoroplastics) are selected as lining or coating materials, and molded lining technology is used to make the valve have metal strength and corrosion resistance. The valve seat uses integral polymer as sealing material, which has excellent sealing performance in a wide range of temperature and pressure; the opening and closing parts (valve disc) are moved up and down along the center axis of the valve seat by the valve stem. On the pipeline, it is mainly used to connect or cut off the medium in the pipeline, but it cannot be used for throttling.

Fluorine-lined right-angle stop valve product application:

Fluorine-lined right-angle stop valve. Fluoroplastic fully lined J41F46 straight-through. J45F46 direct current. J44F46 angle stop valve, compact structure. Flexible opening and closing. Strong corrosion resistance. Short stroke (usually 1/4 of the nominal diameter) and other advantages, widely used in petroleum. Cut off the medium in pipeline systems such as chemical industry, but it should be emphasized that it is strictly forbidden to adjust the flow of fluoroplastic lined stop valves, so as not to save. The high-speed medium flow generated at the orifice erodes and damages the sealing surface. The valve disc and valve stem of the fluorine right-angle stop valve are designed as an integrated structure to prevent internal components from rushing out of the valve body due to pipeline pressure fluctuations. Compact structure and safe use.

Structural features of fluorine-lined right-angle stop valve

1. The stop valve structure is simpler than the gate valve, and it is easier to manufacture and maintain.

2. The sealing surface is not easy to wear and scratch, with good sealing performance and long service life.

3. The valve disc has a small stroke, short opening and closing time, and small valve height.

4. The valve disc and the valve stem are designed as an integrated structure, which is compact and safe to use.

5. The stop valve has three angular structural forms: straight-through type, direct-current type, and direct-current type. Among them, the straight-through type is more commonly used, and the angle steel can be installed at the corner of the pipeline system. The direct-current flow resistance is the smallest among the stop valves.

6. Pneumatic and electric devices can be configured according to user needs to meet the needs of remote control and program control.

7. The lining material of the replacement parts can be applied to various media.
