When the pressure inside the equipment exceeds the specified working pressure and reaches the opening pressure of the safety valve, the internal medium acting on the valve is greater than the force exerted on it by the loading mechanism, so the valve valve leaves the seat, the safety valve opens, the medium inside the equipment is discharged through the seat. At this point, the internal pressure on the disc above the force is less than the loading mechanism applied to it above the force, the disc and tight pressure on the seat, the media stop discharge, equipment to maintain normal working pressure to continue to operate. Therefore, the relief valve is through the disc medium force and the loading mechanism force, automatically close or open to prevent the purpose of overpressure equipment.

      Z45X underground elastic seat seal gate valve is also called lifting rod gate valve, open rod gate valve. There is usually a trapezoidal thread in the lifting rod, through the nuts at the top of the valve and valve body guide groove, the rotation movement into a straight line, that is, the operating torque into the operating thrust. When the valve is opened and the gate lift is equal to 1:1 of the valve size, the flow path is completely clear, but this position cannot be monitored during operation. In practice, the valve stem is marked by the vertex, that is, the position of the fixed open, as its full open position. In order to consider the temperature change in the lock phenomenon, usually in the open to the vertex position, and then back, 1/2-1 circle, as the full open valve position. Therefore, the full open position of the valve is determined by the position of the gate (i.e., travel >).
