一、进口电动软密封蝶阀产品概述

进口电动软密封蝶阀是由橡胶软密封的蝶阀与VTON的电动执行器机构配套，可以用来开关以及输入控制信号（4~20mA或1~5VDC）及单向电源即可控制运转调节的蝶阀；电动蝶阀具有功能强、体积小、轻便宜人、性能可靠、配套简单、流通能力大、电动蝶阀特别是适合于介质粘稠、含颗粒、纤维性质的场合。目前该电动调节蝶阀广泛应用于食品、环保、轻工、石油、造纸、化工、教学和科研设备、电力等行业的工业自动控制系统中。

Electric soft sealed butterfly valve is a butterfly valve that is equipped with rubber soft sealed butterfly valve and VTON electric actuator mechanism. It can be used for switching, inputting control signals (4-20mA or 1-5VDC), and one-way power supply to control the operation and adjustment of the butterfly valve; Electric butterfly valves have strong functions, small size, lightweight and pleasant, reliable performance, simple matching, and large flow capacity. Electric butterfly valves are especially suitable for situations with viscous media, particles, and fiber properties. At present, the electric regulating butterfly valve is widely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical industry, teaching and research equipment, and power.

二、进口电动软密封蝶阀产品特点

1、小巧轻便，容易拆装及维修，并可在任意位置安装。

2、结构简单、紧凑，操作扭矩小，90度回转开启迅速。

3、流量特性趋直线，调节性能好。

4、蝶板与阀杆的连接采用无销钉结构，克服了有可能的内泄漏点。

5、密封件可更换，且密封可靠达到双向密封。

6、蝶板可根据用户要求喷涂覆层，如尼龙或聚四氟类。

7、软密封蝶阀：密封副的两侧一侧是金属材料,另一侧是有弹性的非金属材料的被称为"软密封".这种密封的密封性能较好,但不耐高温,易磨损,机械性较差.如:钢+橡胶;钢+四氟聚乙烯等。

1. Compact and lightweight, easy to disassemble and repair, and can be installed in any position.

2. Simple and compact structure, low operating torque, and quick opening with a 90 degree rotation.

3. The flow characteristics tend to be linear, and the regulation performance is good.

4. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possibility of internal leakage points.

5. The sealing element can be replaced and the sealing is reliable, achieving bi-directional sealing.

6. Butterfly plates can be sprayed with coatings according to user requirements, such as nylon or polytetrafluoro.

7. Soft sealed butterfly valve: A type of valve with metal material on one side and elastic non-metallic material on the other side of the sealing pair is called a "soft seal". This type of seal has good sealing performance, but is not resistant to high temperatures, is prone to wear, and has poor mechanical properties, such as steel and rubber; Steel+PTFE, etc.
