变压器蝶阀 LT型系列DN40-600 变压器配件 蝶阀阀门 逆止阀

　　1、蝶阀具有结构简单、体积小、重量轻、材料耗用省，安装尺寸小，开关迅速、90°往复回转，驱动力矩小等特点，用于截断、接通、调节管路中的介质，具有良好的流体控制特性和关闭密封性能。

　　1. Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast switching, 90 ° reciprocating rotation, small driving torque, etc. it is used to cut off, connect and adjust the medium in the pipeline, and has good fluid control characteristics and closing sealing performance.

　　2、蝶阀可以运送泥浆，在管道口积存液体最少。 低压下，可以实现良好的密封。 调节性能好。

　　2. The butterfly valve can transport mud, and the liquid accumulated at the pipe mouth is the least. Good sealing can be achieved under low pressure. Good adjustment performance.

　　3、蝶板的流线型设计，使流体阻力损失小，可谓是一种节能型产品。

　　3. The streamlined design of the butterfly plate makes the fluid resistance loss small, which can be described as an energy-saving product.

　　4、阀杆为通杆结构，经过调质处理，有良好的综合力学性能和抗腐蚀性，抗擦伤性。蝶阀启闭时阀杆只作旋转运动而不作升降运行，阀杆的填料不易破坏，密封可靠。与蝶板锥销固定，外伸端为防冲出型设计，以免在阀杆与蝶板连接处意外断裂时阀杆崩出。

　　4. The valve stem is a through rod structure, which has been quenched and tempered, and has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is opened and closed, the valve stem only rotates without lifting operation. The packing of the valve stem is not easy to be damaged and the sealing is reliable. It is fixed with the taper pin of the butterfly plate, and the extended end is designed to prevent the valve rod from bursting out when the connection between the valve rod and the butterfly plate is accidentally broken.

　　5、 连接方式有法兰连接、对夹连接、对焊连接及凸耳对夹连接。

　　5. The connection methods include flange connection, wafer connection, butt welding connection and lug wafer connection.

　　驱动形式有手动、蜗轮传动、电动、气动、液动、电液联动等，可实现远距离控制和自动化操作。

　　The driving forms include manual, worm gear drive, electric, pneumatic, hydraulic and electro-hydraulic linkage, which can realize remote control and automatic operation.
