Abstract

一种分体式可拆卸阀座,该阀座分为阀座段和阀座扩散段,阀座段和阀座扩散段通过螺栓连接成一体后,再与阀体的底部螺接。本实用新型的优点是采用分体式,实现了在线拆卸、维护、更换,提高了阀门的经济性能和使用性能,提高了效率。

Description

分体式可拆卸阀座
技术领域
本实用新型涉及一种适用于高性能角式黑水调节阀的阀芯,特别涉及一种在黑水、渣水中含有颗粒并有腐蚀性的工况下阀门的分体式可拆卸阀座。
背景技术
含固体颗粒的黑水、渣水、灰水,尤其是黑水中含有氯离子、氨、钾盐、硫化氢、磷酸等强腐蚀介质,黑水、渣水、灰水等在流经调节阀时会有阻塞流发生,高速流体产生闪蒸、空化,前后压差特别大,并且介质中颗粒会结垢粘连阀内件。传统的解决方法是既将导向部分下移,又将阀内件及流道表面硬化处理;但经常会发生阀座迅速被冲蚀成不规则形状,其后几乎完全被冲蚀,而阀门后的管道也会迅速被冲刷,埋下了安全隐患,阀座的寿命短。阀座采用上装式固定在阀体腔体内,阀座又是最易损坏、最关键的阀内件,更换、维护阀座涉及到上阀盖、执行机构、电气控制件等,无法实现在线更换维护。
实用新型内容
本实用新型所要解决的技术问题是要提供一种能在线更换维护的分体式可拆卸阀座。
为了解决以上的技术问题,本实用新型提供了一种分体式可拆卸阀座,该阀座分为阀座段和阀座扩散段,阀座段和阀座扩散段通过螺栓连接成一体后,再与阀体的底部螺接。
所述的阀座扩散段的内径向外扩散,呈喇叭状。
本实用新型应用于KSA文丘里黑水调节阀,阀座采用分体式,现场只需将变径法兰两端螺栓拆卸,既可将阀座方便拿出,进行更换或维护,同时阀芯也可以在线维护。
本实用新型的优越功效在于:
1)阀座采用分体式,实现了在线拆卸、维护、更换,提高了阀门的经济性能和使用性能,提高了效率;
2)本实用新型应用于KSA文丘里黑水调节阀,阀座采用碳化钨烧结体镶嵌件,其硬度达到HRA≥89,有着优越抗冲刷、抗腐蚀能力;
3)阀座扩散段应用了“文丘里”原理,减少液体介质产生闪蒸、空化对阀体及阀体后段管道的破坏,不仅使阀门寿命增加,更主要的是避免了管道的安全隐患。
附图说明

1-阀座段;  2-阀座扩散段;
3-螺栓;    4-阀体;
5-阀芯。
具体实施方式
以下结合附图,对本实用新型作进一步的描述。
如图1和图2所示,本实用新型提供了一种分体式可拆卸阀座,该阀座分为阀座段1和阀座扩散段2,阀座段1和阀座扩散段2通过螺栓3连接成一体后,再与阀体4的底部螺接。
所述的阀座扩散段2的内径向外扩散,呈喇叭状。
本实用新型应用于KSA文丘里黑水调节阀,阀座采用分体式,现场只需将变径法兰两端螺栓拆卸,既可将阀座方便拿出,进行更换或维护,同时阀芯也可以在线维护。
