Abstract

本实用新型涉及一种闸阀,包括阀体、阀座、闸板、阀杆、阀盖、传动装置、密封件和安装件,主要是阀杆与阀盖之间的密封采用氟橡胶密封圈。具有启闭轻便、结构简单等优点,适用于低温、低压介质管道的阀门。

Description

闸阀
技术领域
本实用新型属于阀门类,具体的说是关于一种闸阀。本实用新型适用于低温、低压介质管道的阀门。
背景技术
闸阀一般由阀体、阀座、闸板、阀杆、阀盖、传动装置、密封件和安装件组成,其密封性能的好坏主要由闸板与阀座之间的密封以及阀杆与阀盖之间的密封决定。现有闸阀的阀杆密封一般采用石墨填料密封,其使用压力、温度高,密封性能好。但其启闭力矩大,而且需要设置填料压盖,结构较复杂。
发明内容
本实用新型的目的是针对现有产品的不足,提供一种启闭轻便、结构简单的闸阀。
本实用新型的技术方案包括阀体、阀座、闸板、阀杆、阀盖、传动装置、密封件和安装件,主要是阀杆与阀盖之间的密封采用氟橡胶密封圈。
本实用新型的优点是阀杆密封采用氟橡胶密封圈,启闭轻便、结构简单。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
如图1所示的闸阀,包括阀体1、阀座、闸板2、阀杆3、阀盖6、传动装置、密封件和安装件。闸板2上端与阀杆3固定连接,阀盖6由螺栓4、螺母5安装阀体1上,两者之间设有O型密封圈13,阀杆3与阀盖6之间的密封采用氟橡胶密封圈7,氟橡胶密封圈7有3个,相邻两个之间设有轴套,启闭过程中氟橡胶密封圈7与阀杆3之间摩擦力小,启闭力矩小。阀杆3的上端设有手轮10、防尘罩11、阀杆螺母12,在阀杆螺母12外侧设有油嘴9和轴承8。
