Description

带防盗装置的阀门
技术领域：
 本实用新型与带防盗装置的阀门有关，尤其与自来水输送系统的防盗阀门有关。
背景技术：
 已有的自来水输送系统水表前用阀门，一般未设防盗装置。带有防盗装置的阀门未设置保护防盗装置的密封圈，常常因雨水和粉尘侵入使防盗系统锈蚀、堵塞而失去防盗功能，不能按要求控制自来水流量，造成自来水公司的经济损失。
实用新型内容：
 本实用新型的目的是提供一种防盗性能好，使用寿命长，便于自来水控制和管理的带防盗装置的阀门。
本实用新型是这样实现的：
本实用新型阀体1的中腔有左、右阀座与闸板2两侧密封面配合，阀杆3与闸板2上端的螺纹孔螺纹连接，阀杆3穿过阀盖4通过传动销10与传动套6连接，阀杆3或阀盖4的动配合面上有O型橡胶密封圈，传动套6或阀盖4的竖向动配合面上有O型橡胶密封圈7，传动套6和阀盖4的水平动配合面上分别有对应的磁钢孔和销孔，磁钢孔直径大于销孔直径，磁钢孔内有磁钢9，销孔内有弹簧5和止动销8。
阀盖4的竖向动配合面上有周向凹槽，凹槽内有O型橡胶密封圈7。
本实用新型有如下优点：
阀盖与传动套之间设有O型橡胶密封圈，使雨水和粉尘不能进入防盗机构内部，避免了其锈蚀和堵塞，确保了防盗系统开关灵活，止动防盗可靠。
附图说明：
图1为本实用新型的结构图。
具体实施方式：
阀体1轴心线的两侧有左、右阀座，闸板2由阀杆3传动上下运动，使阀门开启或关闭。阀体1与阀盖4连接形成阀腔。阀杆3穿过阀盖4经传动销10与传动套6连接，传动套6与阀盖4之间有O型橡胶密封圈7密封。磁钢9在传动套6的磁钢孔中。阀盖4上开有销孔，孔中有弹簧5和止动销8，弹簧5将止动销8顶入传动套6的磁钢孔中，锁定传动套6不能转动，使得由传动套6带动的阀杆3不能带动闸板上下运动。当采用带磁铁的工具，迫使磁钢9下移，将止动销8推出传动套中的磁钢孔，当止动销上端面与阀盖4上端面在同一平面时，带磁铁的工具转动传动套6带动阀杆3转动，使闸板作上下运动。
阀体1左、右两侧有内螺纹，通过内螺纹与管道外螺纹连接。
