When the high pressure globe valve is in operation, the stuffing box extends toward the end of the disk and protrudes from the bonnet, forming an inverted taper with an end diameter greater than the diameter of the mating section with the bonnet. A sealing ring corresponding to the shape of the gap is provided in the annular gap formed between the cone of the inverted cone on the stuffing box, the inner hole of the valve body and the bonnet face the end face of the high pressure globe valve. Using the above-mentioned technical scheme, the use of the pressure of the liquid medium itself to achieve the purpose of sealing, the greater the pressure, the larger the sealing force, the more reliable the sealing, making it a pressure seal globe valve.

When the temperature and pressure fluctuate under high pressure, the sealing performance is good and the sealing is reliable. Compared with the forced sealing, high pressure globe valve does not require a large bolt preload. The median flange is small in size, light in weight, and compact in structure.

The main features of the high pressure globe valve:
