The multi-functional principle of intelligent multi-function well head equipment operating part
At the inwall of valve body, flashboard, valve seat, oil pipe four-way, little four-way, flange, all and the position built-up welding special material wear-and corrosion-resistant layer that fluid directly contacts under the prerequisite that keeps strength of parent, improve the wear-corrosion resistance of inwall;
No rubber seal technology adopts plastics king PTFE as basic material, adds hardness and rigidity that 15% carbon fiber improves basic material, is bumped into tensile spring in lip inside and strengthens lip elasticity.
During use, pressure is from one section entering of lip, and the inside and outside wall in the tight-lipped subsides of the effect lower lip hole of tensile spring provides initial sealing, and pressure is big more, and the lip tensile force is big more, and sealing effectiveness is good more.
