Description

一种新型蝶阀
[技术领域]
本实用新型涉及阀门技术领域，尤其是一种新型蝶阀。 
[背景技术]
传统的硬密封蝶阀中的密封垫片一般采用石墨垫片或石棉垫片，阀门关闭后，靠密封副之间的挤压力达到密封效果；当工作压力在4.0MPa以上时，极易造成密封圈本身的损坏。这两种垫片的最高承压能力一般为2.5MPa，耐温仅达80℃仅适用于低温低压场合。 
[发明内容]
为解决上述问题，本实用新型提供了以下技术方案：一种新型蝶阀，其特征在于，包括阀体、蝶板、密封圈、阀杆和耐磨密封，所述一种新型蝶阀，设有耐磨密封，耐磨密封镶嵌在阀体或蝶板上，所述镶嵌在阀体或蝶板上的耐磨密封，采用钛合金制成，所形成的密封圈为金属硬密封结构。 
本发明有益效果：镶嵌在阀体或蝶板上的耐磨密封，具备良好的密封性能，具有耐高温、高压，抗腐蚀、寿命长等特点，操作省力，灵活可靠。可广泛应用于冶金、石化、热电和热力等行业的管道系统上，作流体的截断和调节用。 
[附图说明]
图1是本实用新型的结构示意图； 
参见图1，1是阀体，2是蝶板，3是阀杆，4是密封圈，5是耐磨密封。 
[具体实施方式]
下面结合附图和具体实施方式对本实用新型作详细描述： 
参照图1，所述一种新型蝶阀，设有耐磨密封，耐磨密封镶嵌在阀体或蝶板上，所述镶嵌在阀体或蝶板上的耐磨密封，采用钛合金制成，所形成的密封圈为金属硬密封结构，与密封圈4一道在高温高压介质通过时，其结构作调节和截断介质。
