Divided by the threaded stem position can be divided into two clear shot valve gate and dark bar. When the valve is closed, the sealing surface can only rely on media pressure to seal, which rely on the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface. Gate valve with the valve stem linear movement, called the lift rod valve (also called clear shot valve). Often movements are trapezoidal threaded rod through the top of the valve guides and valve nut on the rotary motion into linear motion, which is the operating torque thrust into action. Open the valve, when the gate valve lift height equal to the diameter of the 1: 1 times, the fluid channel is completely smooth, but at run time, this position is not monitored. Actual use, is the apex of the stem as a sign that the fixed position, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the position of the valve fully open. Therefore, the fully open position of the valve, according to gate position (ie, travel> to determine. Stainless steel valve, forged steel valve, flange valve, flanged ball valve, gate valve, some two-piece ball valve, the stem nut is located at the gate on the handwheel drive stem rotation, leaving the gate upgrade, this valve is called the rotating rod valve or valve called the dark bar 3] [ANSI flange valve installation - Former Riverstone 1. Install the valve should be checked valve cavity and sealing surfaces and other parts, does not allow dirt or sand attached; 2. The joints bolts evenly tightened requirements; 3. Check the packing requirements of pressed parts, both to ensure the packing seal, but also to ensure the gate open and flexible; 4. User Before installing the valve, the valve must be calibrated model, connection size and attention to the medium flow, to ensure consistency with the requirements of the valve; 5. user when installing the valve, the valve must set aside the necessary drive space; 6. Drive wiring circuit diagram device shall be; 7. valve must be regularly maintained, not free collision and squeeze to affect a seal, ① American standard steel flange valve product name and model ② American Standard steel flange valve diameter. ③ American Standard steel flange valve with an attachment so we can correct for your selection.
