V-ball for the overlapping continuous reforming catalyst device to control the flow path in the flow of solid particles, but as part of a three valve isolation system, a total of four full-device, installed in the regenerated catalyst and spent catalyst flows vertical pipe. This valve combines the effectiveness of the firm ball valves and angle valve V-ball together vendors, shearing between the open V-shaped notch in the ball and the ball sealing contributed to a smooth and unhindered plug operation, especially for solid materials. The valve body is 316SS, surfacing Stellite alloy, sealed for Stellite hard seal with the seal protector ring and sealed with a corresponding spring shims to adjust the thickness available V-ball in the center of the valve body and V-shaped gap between the ball and the metal seal remains within a certain range, such a structure can greatly reduce the catalyst and the valve, valve seat wear, preventing the closing valve inch chopped catalyst while causing forward and reverse maximum allowable leakage rate keep V-ball on the required standards and meet N, gas isolation requirements. Ball valves are generally reduced diameter and channel diameter indented two structures. No kind of structure perish; flow resistance coefficients are relatively small ball. Especially the so-called full-flow-type V-ball offer, namely - port ball valve, due to its channel diameter equal to pipe diameter, local resistance loss only if an equal length of the pipe friction V-ball manufacturers, that all valves, this valve The minimum flow resistance. In the rocket launch and test systems, require pipeline resistance as possible. There are two ways to reduce the resistance of the piping system: First, reduce the fluid flow rate, which requires increasing the diameter and valve size, which often have a negative impact on the economy of the pipeline system, especially for low-temperature transport system ( liquid hydrogen) is extremely unfavorable; First reduce local resistance of the valve, therefore, ball naturally became the best choice.
