Fully Welded Ball Valve The Higher The Pressure, The More Reliable The Seal

- May 31, 2017 -

Fully Welded Ball Valve is mainly applied to all kinds of fire power station on the pipeline, cut off or connected to the pipeline medium. Applicable medium: water, steam and other non-corrosive media. Forged steel valves and other valve products compared to the characteristics of high temperature and pressure, unique self-sealing design, the higher the pressure, the more reliable sealing. Due to the performance of technical characteristics, the special conditions of the product also formed a substitute for other products can not be the characteristics.

    Characteristics of Full Welded Ball Valve for Forged Steel

    Fully Welded Ball Valve is mainly applied to all kinds of fire power station on the pipeline, cut off or connected to the pipeline medium. Applicable medium: water, steam and other non-corrosive media. Forged steel valves and other valve products compared to the characteristics of high temperature and pressure, unique self-sealing design, the higher the pressure, the more reliable sealing. Due to the performance of technical characteristics, the special conditions of the product also formed a substitute for other products can not be the characteristics.

    Forged steel valves often overlook the problem of greaseiness. Grease gun after refueling, the operator low temperature cut valve selection valve and grease the way after the connection, the injection operation. There are two forged steel gate valve situation: on the one hand the amount of grease less filling less, sealing surface due to lack of lubricant to speed up wear and tear. On the other hand grease too much, resulting in waste. Is not based on the type of valve type, the different valve sealing capacity for accurate calculation. You can calculate the valve size and type of sealing capacity, and then reasonable to inject the right amount of grease.

    Fully Welded Ball Valve  maintenance

    Ball valve maintenance are generally in the open state, under special circumstances choose to close maintenance. Other valves can not be arbitrarily in place.

    Forged steel plus long side gate valve to observe the valve diameter and seal ring flush. Such as ball valve, if there is open bit interference, can be adjusted in the open bit limiter, confirm the diameter straight after locking. Adjust the limit can not only pursue the opening or closing side of the position, to the overall consideration. If the open position is flush, not in place, will cause the valve is not strict. Similarly, adjust the customs in place, but also consider the corresponding adjustment of the opening bit. Make sure the valve is at right angles. After filling the grease, it must be sealed. To avoid impurities into, or grease mouth lipid oxidation, capping to apply anti-rust grease, to avoid rust. So that the next operation when applied.

    Forged steel cryogenic valves should be considered in the future order of specific delivery of oil specific treatment. In view of the different quality of diesel and gasoline, gasoline should be considered the erosion and decomposition capacity. After the valve operation, encountered in the gasoline section of the operation, the timely replenishment of grease to prevent wear and tear occurred. When filling grease,Fully Welded Ball Valve  do not ignore the grease on the stem part. Valve shaft parts have sliding sleeve or packing, also need to maintain the lubrication state, in order to reduce the friction when the operation, if not to ensure lubrication, the electric torque when the increase in wear parts, manual operation when the switch effort.

    Some ball valve valve marked with arrows, if not with the English FIOW writing, the role of the seat for the seal, not as a medium flow reference, the valve from the opposite direction of the vent. Normally, a two-seater sealed ball valve has a two-way flow.

    Valve maintenance, but also pay attention to the electric head and its transmission mechanism of water problems. Especially in the rainy season into the rain. One is to drive or drive shaft rust, the second is frozen in winter. Causing the motor to operate when the torque is too large,Fully Welded Ball Valve  damage to the transmission parts will make the motor no load or super torque protection jump can not achieve electric operation. Transmission parts are damaged, manual operation can not be carried out. In the super torque protection action, the manual operation can not switch, such as forced operation, will damage the internal alloy parts.
