Notes: Serial valve connecting flange and butt-welding terminal size can be designed at customers'request. The material of the main parts and sealing surface of the valve can be designed and selected according to the actual working conditions or the special requirements of users.

 

 

1. It has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy installation and easy disassembly.

2. When the valve is fully opened, the flow resistance coefficient is very small, and the valve will eliminate the function of the valve disc and the dirt on the sealing surface every time the valve is opened and closed.

3. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.

4. It is widely used in oil and water steam pipelines such as petrochemical industry and thermal power plants to connect or cut off the intermediate quality of pipelines. The sealing surface of the opening and closing device has compact structure and reasonable design.

Q: What should I pay attention to when choosing a blowdown valve?

A: When choosing a common blowdown valve, it is necessary to make a reasonable selection according to the characteristics of the medium, temperature, pressure and other conditions. Once the selection is improper, it will bring safety risks and economic losses to production, so you should choose carefully and consult professionals. When selecting a blowdown valve, the following points need to be taken into account:

1. Valve material: sewage valve need to have the characteristics of corrosion resistance and high temperature resistance, generally choose stainless steel, titanium alloy and other materials.

2. Sealing: It is necessary to ensure good sealing and avoid liquid leakage when it is used.

3. Discharge capacity: The drain valve needs to have a high discharge capacity and can quickly discharge waste and impurities in the liquid.

4. Control mode: manual, electromagnetic and other control modes can be used to select according to specific needs.

 

Q: How many types of wear can materials have?

A: Material wear, generally can be divided into the following types: adhesive wear, that is, metal to metal wear; Abrasive wear; Erosion wear; Corrosion wear; Surface fatigue wear.

 

Adhesive wear: Adhesive wear is usually caused by sliding between metals. When two pieces of metal are pressed together, the uneven surfaces touch each other to form joints, and when sliding these joints break to form new joints, eventually forming abrasive particles. The reason why people do not want adhesive wear is that :

a) the wear of the material will increase the dimensional tolerance of the part, and then make the valve closing mechanism leak and damage;

b) Abrasive debris, especially large particles formed by abrasion or adhesion, will jam the moving parts of the valve and make the valve fail.

 

Abrasive wear: Abrasive wear occurs when hard particles cut the material under load. Hard particles such as sand, alumina, carbide, etc. are pressed into the surface of the soft metal under normal load, and the grooves are carved out when sliding, thus forming metal chips or loose grinding chips. At this point, abrasive wear and "microcutting" are similar.

 

Erosion wear: Erosion wear is a special form of abrasive wear caused by the cutting effect of the particles suspended in the fluid under the action of kinetic energy. This wear will occur in valves used to transport solids, such as those used to transport mud or the closed funnel valves commonly used in blast furnace feeding systems.

 

Corrosion wear: If the worn surface is subjected to chemical corrosion, it will occur corrosion wear. Most corrosion resistant alloys initially form a protective layer due to chemical corrosion, however, this protective layer may be worn off when the surface slides. The exposed metal is exposed to the surrounding corrosive media, which increases the wear rate (oxidative wear and corrosive wear are synonymous).

 

Surface fatigue wear: When repeated sliding or rolling on a closed track, the phenomenon of surface fatigue wear can be observed. As cracks on or under the surface of the part expand under repeated cyclic stress, fatigue wear often results in pitting on the surface. Surface fatigue wear - usually occurs on rolling elements such as bearings, gears and other parts.

 

In addition to the above types of wear, there are fretting wear or corrosion, cavitation, etc. - some special wear types.
