高性能系列 HIGH PERFORMANCE

两片式刀闸阀因阀体采用两片式组合而得名。

1、两片式刀型闸阀主体采用两片对称式铸造结构，其阀体同比老款一体式刀型闸阀更加厚实强度更高，阀体里外全采用CNC高精密加工，使其整体精度更高，各方面密封更好，阀门更耐介质冲刷，外观更加顺滑平整及美观。

2、阀门主体为全通径设计，并通径内腔设计成合理的斜坡导流冲刷口结构，可有效提高介质通过阀腔流道的顺畅性，并有效解决了老款一体式刀型闸阀介质卡槽关闭不严导致密封泄露等弊端问题。

3、独特的双向密封结构可实现双向承压不卡槽不泄露不受冲刷等影响，使阀门使用寿命大大提升，承压能力超标准化。

4、两片式刀闸阀更加适用与矿浆、矿渣、矿粉等各种介质形态复杂，冲刷力大，密封要求高，使用环境恶劣，高耐磨高腐蚀等特殊工况。

5、以上结构均有实用新型专利及外观专利，请尊重本司知识产权，崇尚创新、诚信守法。

KLP 两片式结构 VAAVESEERISTICS

1、阀座采用U型结构一体式热熔模压橡胶密封圈，其密封圈密度更高，回弹性更好，更加耐磨耐水耐油耐冲刷。2、橡胶阀座镶嵌于阀腔流道内，受两片阀体全方位包裹，使其95%以上面积不受介质冲刷，真正做到延长阀门的使用寿命及密封性。3、U型阀座橡胶密封接触面设计为凸V型结构，使其接触介质或闸板面积更小，可有效提高阀座的使用寿命，并可有效解决扭矩大、推力紧、启闭难等问题。4、阀座橡胶中道上密封设计为凹U型结构，使其接触闸板面积更小、回弹性更好、扭力更轻、密封更强，并可加装针芯注胶口，注胶口可多次保障橡胶后期磨损后通过外力注密封胶修补橡胶的密封性。5、阀座与阀体间设计有弧形刮板结构，选用四氟密封可有效刮除闸板上粘黏的介质，提高阀座整体使用寿命。

暗板带盖刀型闸阀又称为燃气专用阀，主要应用于燃气以及排污等气体或液体管道。有利于防止上封盖泄漏。主要特点是安装方便，节约成本，耐磨耐损。一般应用于粉料、浆液、气体、液体等介质传输管道。此种刀型闸的上密封突破了常规的密封形式，采用上盖结构，使得上密封由大面积的矩形密封改成了小面积的圆周密封，密封性能大大提高。在圆周密封的基础上，又采用了目前国际上先进的浮动密封结构，使得上密封达到了与管道同寿命的程度，从而整体上提高了阀门的使用寿命。此种闸阀在手轮顶部加装封套装置后，可以使阀门活动部件全部处于封闭状态，闸板和阀杆的丝杆传动不会因润滑油干枯而卡涩。特别适合在粉尘及干燥的恶劣环境中长期正常工作。

穿透式插板阀是一种闸板与阀座始终紧密接触密封的阀门，其原理是闸板上开有一个通径大小的圆口，通过闸板启闭使得闸板上圆口跟通径做完全脱离和相吻合的动作。此阀门的优点在于阀体通径无凹槽，介质不会卡阻堵塞，并且具有全通径流通特性，适合粉体颗粒介质的管道中使用。其密封结构可以分软密封、硬密封结构。

1产品基本参数

密封原理

1、开启阀门：当阀门逆时针旋转开启阀门时，阀座橡胶受内部弹性钢圈及自身弹性影响，随阀板的逐渐提升同时同步闭合阀座橡胶，阀座以此阻挡介质不会流到阀腔内部。当阀门完全处在开启状态时，阀板与阀座橡胶完全分离并萎缩在阀腔内部，以此保障阀体流道达到全密封状态阻止介质分散流进阀腔。

2、关闭阀门：当阀门顺时针旋转关闭阀门时，随着闸板的双刀口截面穿过橡胶阀座，对橡胶形成压力使橡胶随阀板的逐渐关闭同时同步挤开阀座橡胶，当阀门完全处在关闭状态时，阀板与阀座橡胶完全贴合，以此保障阀体流道达到全密封状态并阻止介质串流泄露及负压回流等。

结构特性

密封性好：独特的密封结构设计，可有效防止介质泄漏，密封间隙调整方便，无跑冒滴漏现象。
耐磨耐腐蚀：硬质合金密封面和不锈钢闸板的材质，使其具有良好的耐磨性和耐腐蚀性，使用寿命长。
操作方便：结构合理，操作灵活，可实现手动、电动、气动等多种操作方式。
维护便捷：易损件集中在左右密封板，更换零件时只需拆开左右阀板，便于维护和更换。
全通径设计：阀门开启时通道内无阻碍，介质流动通畅，不会出现沉积、堵塞等问题。

密封原理

开关过程：通过升降驱动机构控制闸板的上下移动来实现阀门的开启和关闭。当阀门开启时，闸板上升，管道内形成全通径，介质可顺畅通过；关闭时，闸板下降与密封面紧密贴合，实现密封。

阀座和闸板之间装配有密封圈组件，包括第一密封圈和第二密封圈，通过密封圈与密封面的紧密配合实现密封。阀体上镶有可胀缩的橡胶封圈，开启时收缩，关闭时密封圈胀开，与阀瓣压紧达到密封。
