Metal hard seal ball valve, hard seal ball valve

Metal hard seal ball valve Overview:

1, the metal hard seal ball valve adopts eccentric structure, in the closing process, the sealing specific pressure between the valve seat and the ball can be rapidly increased, so as to ensure the reliable sealing of the sealing pair. When THE VALVE IS OPEN, the SEAT and the ball can be quickly separated, which effectively reduces the operating torque and minimizes the possibility of control damage between the seat surface and the ball. 2, the metal hard seal floating ball valve (as shown in the figure) adopts the elastic loading structure to ensure the contact between the sealing surface of the ball and the valve seat seal under the normal closing condition. Under the high temperature working condition, it can effectively compensate the thermal expansion of the internal parts and avoid the blockage caused by high temperature. It is suitable for the use of medium and small diameter high temperature occasions. 3, the metal hard seal fixed ball valve in addition to the eccentric characteristics of the metal hard seal eccentric ball valve, other advantages in this service, in addition, it can be used two-way, and not easy to sink in the cavity

According to the user's working conditions, the sewage outlet can also be set up in the middle cavity. 4. The surface of the ball of the metal hard sealing ball valve is treated with special hardening, and the whole seat is made of special hard materials or local hard surfacing materials to ensure that there is a suitable hardness difference between the sealing pair.

5, because the surface of the sphere is treated with special surface hardening, the valve seat is made of surfacing hard alloy, so in the process of opening and closing the valve can well withstand the medium flushing, especially suitable

It is suitable for solid particles and abrasive media.

6. In addition to the special surface treatment of the surface of the ball and the valve seat, flexible graphite and metal winding gaskets are used in other sealing materials, so they can be used at high temperature and high pressure

Working condition, and with fire resistance function.

The main application fields of metal hard seal ball valve:

Petrochemical industry: in refineries, chemical plants, metal hard seal ball valve is used to deal with high temperature, high pressure, flammable and explosive and corrosive media, such as crude oil, natural gas, petrochemical products, etc.

Power industry: in the steam and water circulation system of power plants, the metal hard seal ball valve can withstand high temperature and high pressure to ensure efficient and stable fluid control.

Metallurgical industry: in the high temperature furnace gas, cooling water system, the metal hard seal ball valve can effectively cope with high temperature and wear, to meet the harsh working environment.

Food and pharmaceutical industry: although the metal hard seal ball valve is not as popular as the sanitary grade valve in these fields, it can also be applied in specific links, such as the treatment of high temperature disinfection media.

Paper, mining, water treatment industry: in these industries, metal hard seal ball valves are suitable for pipe systems containing solid particles or corrosive media, and their wear and corrosion resistance characteristics are particularly important
