Q41 Hard-sealed ball valve, ball valve

Q41 Hard-sealed Ball Valve Introduction:

The Q41 hard-sealed ball valve is widely used in various systems such as the extraction, refining, and pipeline transportation of oil, natural gas, coal, and minerals; in the production of chemical products, medicine, and food; in the power production systems of hydropower, thermal power, and nuclear power; in the water supply, heating, and gas supply systems of cities and industrial enterprises; in the irrigation and drainage systems of farmlands; and in the production systems of metallurgy. It is an important mechanical product closely related to production construction, national defense construction, and people's lives. The ball valve is sealed in various pipeline systems and is used to cut off or connect the medium flow, allowing the medium to be transported to designated points according to the predetermined process.

Characteristics and Advantages of Q41 Hard-sealed Ball Valve:

1. The manual part can be a steel plate pressed handle or a stainless steel cast handle. The handle is equipped with a limit structure, setting limits at the positions of valve opening and closing. When the valve is used in key devices, the limit block is provided with a lock hole to lock the switch position to avoid accidental operation. 2. The valve stem is made by overall forging and tempering of A182F (1Cr13), with a hardness of 220-250 B220. 3. The packing of the valve selects braided, flexible graphite sealing ring or tetrafluoroethylene sealing ring, enabling the valve stem to achieve reliable sealing under certain lubrication conditions. 4. According to needs, the ball valve can be designed as an anti-static structure, with conductive springs set between the ball, the valve stem, and the valve body. 5. The sealing pair forms are diverse. Different working conditions can select soft sealing, hard sealing, fire-resistant valve seats, etc. Structures; for DN150 and below, it is in the form of floating ball. 6. Auxiliary sealing structures can be set at the valve seat, and an injection valve is added at the valve seat and valve stem positions. In emergency situations, it can temporarily seal, and the valve stem can be lengthened as needed to accommodate the layout requirements of the site.
