一、进口电动对夹蝶阀产品概述

进口电动对夹蝶阀（美国威盾VTON），Electric Wafer Butterfly valve，是指由角行程电动执行器和对夹式软密封蝶阀或者对夹式硬密封蝶阀组成，由电动执行器驱动蝶阀阀板的开启和关闭的蝶阀，也可以配置定位器，对介质进行流量，压力，温度的智能调节。

美国威盾电动对夹蝶阀主要产品有电动铸钢蝶阀，电动不锈钢蝶阀，电动对夹软密封蝶阀，电动对夹硬密封蝶阀。

Electric Wafer Butterfly Valve (VTON) refers to a butterfly valve composed of an angle stroke electric actuator, a soft seal butterfly valve or a hard seal butterfly valve. It is driven by an electric actuator to open and close the butterfly valve plate. It can also be equipped with a locator to intelligently adjust the flow rate, pressure, and temperature of the medium.

The main products of Weidun Electric Butterfly Valve in the United States include electric cast steel butterfly valves, electric stainless steel butterfly valves, electric soft seal butterfly valves, and electric hard seal butterfly valves.

二、进口电动对夹蝶阀产品特点

1、电动对夹蝶阀主要结构由阀体，阀瓣，阀座，阀杆及传动操作机构等部件组成，阀座采用可脱卸构造，并可根据不同介质的物理化学特性，选用相应的耐高温，耐低温，耐腐蚀，耐光，耐老化材质。

2、电动对夹蝶阀采用中线型结构无偏心设计，具有显著的操作扭矩低的特征，配置电动装置时的经济性显著；采用衬胶结构，蝶板圆周形密封面精密加工至较高的光洁度，对橡胶阀座的摩擦系数极低，阀门使用寿命较长；阀板密封面流态特性呈线性状态，具有较小的流阻系数，阀门流阻小；独特设计的模压橡胶阀座具有极佳的均衡性和支撑性，有效避免受力不均造成的对橡胶的破坏，阀门处全关位置时，橡胶处于最佳的压缩状态以保持零泄漏。

3、电动对夹蝶阀球墨铸铁壳体内外表面可采用高温静电喷涂环氧树脂粉末涂层，涂层具有较高的耐腐蚀性能，与球墨铸铁基体具有极高的结合强度，涂层度为0.2—0.5mm。  

1. The main structure of electric clamp butterfly valve is composed of valve body, valve disc, valve seat, valve stem, and transmission operating mechanism. The valve seat adopts a detachable structure, and corresponding materials that are resistant to high temperature, low temperature, corrosion, light, and aging can be selected according to the physical and chemical properties of different media.

2. The electric clamp butterfly valve adopts a medium linear structure with no eccentricity design, which has a significant feature of low operating torque and significant economic efficiency when equipped with an electric device; Adopting a rubber lined structure, the butterfly plate's circumferential sealing surface is precision machined to a high smoothness, with extremely low friction coefficient for the rubber valve seat and a long service life of the valve; The flow characteristics of the valve plate sealing surface are linear, with a small flow resistance coefficient, resulting in a small valve flow resistance; The uniquely designed molded rubber valve seat has excellent balance and support, effectively avoiding damage to the rubber caused by uneven force. When the valve is in the fully closed position, the rubber is in the best compression state to maintain zero leakage.

3. The inner and outer surfaces of the electric clamp butterfly valve ductile iron shell can be coated with high-temperature electrostatic spraying epoxy resin powder, which has high corrosion resistance and extremely high bonding strength with the ductile iron matrix. The coating degree is 0.2-0.5mm.
