Core Structure: The Hardware Foundation for Opening and Closing Functions

Core Opening and Closing Component—Gate Disc

The gate plate is the core opening and  ending  element, which moves up and down  vertical to the fluid to control on- off; the core  point of the soft- sealed gate  stopcock is that the sealing  face of the gate plate is covered with soft accoutrements .

Sealing support components——valve seat and valve body

The stopcock seat and  stopcock body are the core of the sealing support;

The stopcock seat and gate plate form a sealing brace, and their accoutrements  are compatible with the medium;

The stopcock body is the  external shell with a  erected- in straight- through channel, and cast iron/ cast  sword ensures pressure bearing. .

Power Transmission Hub——Valve Stem and Operating Mechanism

The  stopcock stem transmits force with the operating medium to drive the gate to open and close;

 The  stopcock stem is divided into rising stem( exposed for easy observation) andnon-rising stem( hidden to save space); the operating medium includes handwheel, electric/ curvaceous , which drives the  stopcock stem to lift.

Working process: Dynamic control of fluid on-off

Opening process: the transition from sealed to conducting

 Operation Detector Manually rotate the handwheel or start the electric/ curvaceous  medium to drive the  stopcock stem overhead;

 Gate separation Separate from the  stopcock seat to form a rotation gap;

 Full conduction The gate rises to the full periphery height to be completely open, and the vertex is turned back half a circle to one circle to  help locking. .

Closing process: Blocking from circulation to sealing

 Rear driving Rear operation drives the gate to descend;

 Sealing fit The gate fits with the  stopcock seat, the elastic gate deforms to fill the gap, and the rigid part is sealed by external force/ medium pressure;

 Channel blocking The sealing  shells fit to cut off the fluid, and the  ending force is controlled to  help damage .

Performance advantages and application limitations

Core Advantages

Low Inflow resistance The straight- through channel has low inflow resistance, suitable for large inflow rates and reducing energy consumption; the soft- sealed type has  fresh tight sealing without leakage, suitable for clean media  similar as drinking water and food;

 Bidirectional inflow No need to distinguish between  bay and outlet, flexible installation

Application Limitations

Slow opening and  ending long stroke, not suitable for  rapid-fire response; soft- sealed type has poor high- temperature resistance and wear resistance, and should avoid high temperatures( ≤ 120 ℃), media containing  patches and strong  sharp media;

 High  conservation bring the sealing  face is  fluently damaged, and  conservation is complicated;

In summary, gate  faucets control the on- off of fluids through the direct movement of the gate plate; soft- sealed  faucets achieve high-  perfection sealing by means of soft accoutrements , are suitable for clean and low- pressure  scripts, and are n’t suitable for high temperatures or harsh media. Clarifying their characteristics can  give a base for design, selection, and  conservation, and  opting  them in combination with working conditions can  insure the safe and effective operation of the system。
