结构及工作原理Structure and working principle
柱塞式截止阀是由阀体、阀盖、阀杆、柱塞、密封圈、手轮等零七八碎件组成(如图)。
当旋转手轮时，通过阀杆带动柱塞，使柱塞顶斜锥面与阀座锥面往复离合，完成阀门的开启和关闭。在阀门中，柱塞与密封圈间采用过盈配合。通过调节阀盖固定螺栓的压紧， 使密封圈被压缩，内圈紧包柱塞外圈紧贴阀腔内壁，这样在密封圈上所产生的径向分力将在于流体的压力，从而保证了密封性，杜绝了外泄漏。由于密封圈采用回弹性强，而靡性高的无毒新型密封材料，所以密封可靠、经久耐用。阀座与柱塞的锥面密封部位，采用优质耐靡材料，能保证阀门的使用寿命。
本阀门结合柱塞阀的无泄漏优点和截止阀的启闭快特点，成为一个结构新颖、用途广 泛的新品种。
Plunger valve by valve body,valve cover,stem,plunger,sealing ring,hand wheel and sporadic form attachments (see chart).
When rotating the handwheel,through the valve rod drives the plunger,the plunger reciprocating inclined cone and seat cone clutch,complete opening and closing of the valve.In the valve,USES the interference fit between plunger and seal.Pressure across the valve cover retaining bolt tight,make the seal ring is compressed,inner ring present tight circle against the valve cavity wall,beyond the Great Wall so on sealing ring radial component force would be generated by the pressure of the fluid,thus ensuring the sealing,to eliminate the extemal leakage.The adoption of resilience is strong,sealing ring and bonding high nontoxic new sealing material,so the sealing is reliable,durable.Seat and taper sealing plunger parts,using high quality materials,resistant to ensure the service life of the valve.This combination plunger without leakage valve advantages,and the characteristics of the valve opening and closing fast,become a new structure,USES a wide range of new varieties.
