Description

一种衬氟蝶阀A fluorine-lined butterfly valve

技术领域technical field

背景技术Background technique

阀门可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油品、液态金属和放射性介质等各种类型流体的流动，在管道上主要起切断和节流作用。蝶阀又叫翻板阀，是一种结构简单的调节阀，可用于低压管道介质的开关控制的蝶阀是指关闭件阀瓣或蝶板为圆盘，围绕阀轴旋转来达到开启与关闭的一种阀。Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media, and mainly play the role of cutting and throttling on the pipeline. Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. Butterfly valve that can be used for on-off control of low-pressure pipeline medium means that the closing member disc or disc is a disc, which rotates around the valve shaft to achieve a one-way opening and closing. kind of valve.

衬氟蝶阀是一种用来实现管路系统通断及流量控制的部件，已在石油、化工、冶金、水电等许多领域中得到即为广泛地应用。衬氟蝶阀通常包括阀体、阀座、蝶板、阀杆。The fluorine-lined butterfly valve is a component used to realize the on-off and flow control of the pipeline system. It has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. Fluorine lined butterfly valve usually includes valve body, valve seat, butterfly plate and valve stem.

蝶阀密封通常通过蝶板与阀体内的阀座紧贴形成密封，在使用一段时间后受介质的压力的影响，衬塑层与阀座易发塑性变形，而由于阀杆分别穿过阀座与蝶板固定连接，这样容易导致阀杆与阀体的接合处发生泄漏，降低了阀门的密封性能，缩短了产品的使用寿命，同时现有的蝶阀结构比较复杂、重量大，不便操作。Butterfly valve seals usually form a seal through the close contact between the butterfly plate and the valve seat in the valve body. After a period of use, affected by the pressure of the medium, the plastic lining layer and the valve seat are prone to plastic deformation, and because the valve stem passes through the valve seat and the valve seat respectively. The butterfly plate is fixedly connected, which easily leads to leakage at the joint of the valve stem and the valve body, which reduces the sealing performance of the valve and shortens the service life of the product.
