Abstract

一种耐冲蚀可调节型旋塞阀，包括阀体和旋塞，软质的阀座固定在阀体中和旋塞密封配合，旋塞内置带有通径的保护套，旋塞和保护套转动配合，该保护套的下根部穿出旋塞并和阀体相对固定。本发明的结构合理，保护套和阀体相对固定，在旋塞转动调节时保护套保持不动，始终挡在阀座的前面，通过的介质只能接触到保护套，不会直接冲刷到阀座，阀座几乎没有冲刷磨损，耐冲蚀性能大大增强，明显减少了阀门的维护检修量，提高了工作效率。

Description

耐冲蚀可调节型旋塞阀
技术领域：本发明涉及一种旋塞阀。
背景技术：较多旋塞阀采用软质的阀座配合旋塞，在旋塞半开调节时，介质流过旋塞会直接冲刷到阀座，损害较大。如果输送的介质腐蚀性强、压力大、流速高，对阀座的冲刷磨损会非常明显，使阀门的维护检修次数增加，影响生产。
发明内容：针对现有技术的不足，本发明提供一种结构合理的耐冲蚀可调节型旋塞阀。
本发明包括阀体和旋塞，软质的阀座固定在阀体中和旋塞密封配合，旋塞内置带有通径的保护套，旋塞和保护套转动配合，该保护套的下根部穿出旋塞并和阀体相对固定。
本发明的结构合理，保护套和阀体相对固定，在旋塞转动调节时保护套保持不动，始终挡在阀座的前面，通过的介质只能接触到保护套，不会直接冲刷到阀座，阀座几乎没有冲刷磨损，耐冲蚀性能大大增强，明显减少了阀门的维护检修量，提高了工作效率。
下面结合附图和实施例进一步说明本发明。
附图说明：图1是实施例的主结构示意图。
图2是图1的A-A剖视图。
图3是图1中保护套的右视图。
图4是图3的B-B剖视图。
图5是图2的半开调节状态示意图。
具体实施方式：如图1至图4所示，阀体1布置有旋塞2，软质的阀座3固定在阀体1中和旋塞2密封配合。旋塞2内置带有通径4的保护套5，旋塞2和保护套5转动配合，该保护套5的下根部穿出旋塞2并和阀体1相对固定。
实际上，旋塞2和保护套5之间一般是间隙配合，这样不影响旋塞2转动，也便于装配。保护套5的下根部是方柱形，阀体1的对应位置设有方形凹坑6配合相对固定。当然，保护套5的下根部也可以是其它造型，只需能够和阀体1相对固定不转动即可。
在旋塞2转动调节时，如图5所示，介质通过需要改变方向，对两侧的冲刷会增强，由于保护套5保持不动，始终挡在阀座3的前面，通过的介质只能接触到保护套5，不会直接冲刷到软质的阀座3。保护套5一般采用金属材质制造，硬度较高，也容易生产。
