闸阀的进口高端规格

原文: 闸阀的种类 ,按密封面配置可分为楔式闸板式闸阀和平行闸板式闸阀 , 楔式闸板式闸阀又可 分为 : 单闸极式、双闸板式和弹性闸板式;平行闸板式闸阀可分为单闸板式和双闸板式。按阀杆的螺纹位置划分,可分为明杆闸阀和暗杆闸阀两种。  闸阀的安装与维护应注意以下事项:  手轮、手柄及传动机构均不允许作起吊用,并严禁碰撞。   双闸板闸阀应垂直安装(即阀杆处于垂直位置 , 手轮在顶部 )。   带有旁通阀的闸阀在开启前应先打开旁通阀(以平衡进出口的压差及减小开启力 )。   带传动机构的闸阀,按产品使用说明书的规定安装。   如果阀门经常开关使用 , 每月至少润滑一次。  结构特点:  长期以来市场上使用的一般闸阀普遍存在着漏水或生锈现象,引进欧洲高科技橡胶及阀门制造技术所生产的弹性座封闸阀,克服了一般闸阀密封不良,生锈等缺陷,弹性座封闸阀利用弹性闸板产生微量弹性变形的补偿作用达到良好的密封效果,该阀具有开关轻巧、密封可靠、弹性记忆佳及使用寿命等显著优点。闸阀的进口高端规格。

译文: Gate valve type, according to the sealing surface configuration can be divided into wedge type gate valve and parallel sluice gate valve gate, wedge gate valve gate can be divided into: single gate type, double disc and flexible disc; Parallel slide gate valve can be divided into single ram and double ram. According to the threads of the valve stem position, can be divided into rising stem gate valves and dark bar gate valve two kinds. Gate valve installation and maintenance should be paid attention to the following items: the handwheel, handle and transmission mechanism are not allowed for lifting, and it is forbidden to collision. Double disc gate valves should be installed vertically (that is, the valve stem in a vertical position, the handwheel at the top). Gate valve with a bypass valve in open open the bypass valve should be taken before (in the balance of import and export of differential pressure and reduce the opening force). Belt transmission mechanism of the gate, according to the regulations of the product instruction manual installation. If the valve switch is used, often lubrication at least once a month. Structure features: on the market for a long time to use a common gate valve is leaking or rusty phenomenon commonly, the company introduced the European high-tech rubber and valve manufacturing technology of elastic seat seal gate valves, overcome the general gate seal bad, rust and other defects, seal gate valves of the elastic base seat using elastic disc produce elastic deformation compensation effect to achieve good sealing effect, this valve has the switch light, reliable sealing, good elastic memory and service life etc.闸阀的进口高端规格。
