Polysilicon ball valve lock or card solutions
1. Valve seat plate spring deformation chamber, the sealing performance is not good, so that the silicon powder into the valve plate spring deformation chamber, resulting in failure to block the leaf spring is blocked, the valve is blocked by the valve seat can not be a good switch. 2. Between the valve body and the ball in the valve when the switch into the silicon powder, so that the ball does not lock the valve smoothly switch. However, this cause requires a working condition, that is, in the case of moist silicon powder can be bonded in the cavity. Silica fume in the case of dry or fluid does not cause such a lock case. If the silicon powder in the case of dry or fluid lock caused the case that is the first case of silicon powder into the valve plate deformation chamber. Solve the above two methods to produce a lock valve: 1. Zigong valve plant is used in the whole "O" -shaped ball, double seat, leaf spring loading structure, the seat seal design wide blade scraper structure, the valve switch Can be removed in the spherical silicon powder bonding, self-cutting self-cleaning function, the leaf spring with double graphite seal structure, the valve seal at the same time, the leaf spring is also sealed, the media will not enter the deformation chamber, so that the leaf spring Was blocked dead, you can meet the requirements for a long time. 2. In the moist silicon clogging valve cavity caused by locking can not switch this special case, we generally advise customers to strengthen the drying effect of silicon powder or switch to V-shaped hemisphere valve valve factory launched to completely solve this blockage problem.
