Abstract

本发明一种对夹式煤渣管道用蝶阀的阀座，它的主要技术方案是：所述阀座包括骨架、衬胶，所述骨架一面设有凹洞，所述凹洞内设凹槽，所述衬胶位于所述凹洞内部，并通过所述凹槽将其固定在所述骨架上。本发明具有以下有益效果：本发明打破以往的衬胶包覆阀座的结构，而是设计成阀座包裹衬胶这一结构形式，阀座骨架由普通碳钢改为153合金铸铁，增加了抗腐蚀耐磨性能；骨架内设凹槽，衬胶不易脱落；衬胶采用高含胶量的高耐磨橡胶，不易撕裂。

Description

一种对夹式煤渣管道用蝶阀的阀座
技术领域
本发明涉及阀门技术领域，具体涉及一种对夹式煤渣管道用蝶阀的阀座。
背景技术
发电厂发电时燃烧煤所产生的大量煤灰渣，通过灰渣泵及管道排入特定灰库，为了保护灰渣泵，延长其使用寿命，我们常在出灰管道上增加一个二次隔离阀，常采用对夹式蝶阀，因其结构简单、体积小巧、拆装方便。但是在使用过程中，常出现阀座进出口沿磨损过甚、衬胶密封层脱落和撕裂导致寿命较短，需要频繁拆卸、抢修、更换。
发明内容
本发明的目的是提供一种耐磨抗腐；衬胶不易脱落、不易撕裂的的阀座。
为了解决背景技术所存在的问题，本发明是采用以下技术方案：一种对夹式煤渣管道用蝶阀的阀座，所述阀座包括骨架1、衬胶2，所述骨架1一面设有凹洞3，所述凹洞3内设凹槽4，所述衬胶2位于所述凹洞3内部，并通过所述凹槽4将其固定在所述骨架1上。
进一步地，所述骨架1采用153合金铸铁制成。
进一步地，所述衬胶2采用含胶量不低于65%的高耐磨橡胶。
本发明具有以下有益效果：本发明打破以往的衬胶包覆阀座的结构，而是设计成阀座包裹衬胶这一结构形式，阀座骨架由普通碳钢改为153合金铸铁，增加了抗腐蚀耐磨性能；骨架内设凹槽，衬胶不易脱落；衬胶采用高含胶量的高耐磨橡胶，不易撕裂。
附图说明
图1为本发明的结构示意图。
    附图标记说明：骨架1、衬胶2、凹洞3、凹槽4。
具体实施方式
下面结合附图对本发明做进一步详细的说明。
本发明一种对夹式煤渣管道用蝶阀的阀座，所述阀座包括由抗腐蚀耐磨性能优良的153合金铸铁制成骨架1和高含胶量的耐磨橡胶制成的衬胶2，所述骨架1一面是水平面，另一面设有凹洞3，所述凹洞3外围一圈设有凹槽4，所述衬胶2位于所述凹洞3内部，并通过所述凹槽4将其固定在所述骨架1上，这种设计使得所述衬胶2不易从所述骨架1脱落，而采用高含胶量的耐磨橡胶材料又使得所述衬胶2不易撕裂，延长了阀座的使用寿命，增强了该蝶阀的整体密封性能，不易泄漏，保证管道的正常工作。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，本领域普通技术人员对本发明的技术方案所做的其他修改或者等同替换，只要不脱离本发明技术方案的精神和范围，均应涵盖在本发明的权利要求范围当中。
