The utility model relates to the technical field of valve manufacture, in particular discloses an anti-theft lock valve, comprising a valve body, a valve core and a valve rod and a valve located in the body and the internal stem is connected with the external lock located in the body and the outer end of valve stem connection locks can drive the valve rod and the valve core rotation, including security the rotary cap lock with a cylindrical shape, the circumference of the outer end of the lock head is provided with a plurality of slots on the outer wall of the lock is provided with a limit structure, anti-theft rotary cap with a cylindrical shape and is sheathed outside the lock and anti-theft card slot on the outer end of the circumference of the rotary cap is provided with a clamping groove corresponding to the the inner wall, anti-theft rotary cap is provided with an annular limit structure corresponding to the limiting groove, anti-theft screw cap with respect to lock free rotation. The utility model has the advantages that when the utility model is used by the external force, only the anti-theft cap rotates, and the lock head and the like are not moved, so that the locking valve can not be opened, and the safety performance of the locking valve is greatly improved.
【技术实现步骤摘要】
本技术涉及阀门制造
,尤其涉及一种防盗锁闭阀。
技术介绍
锁闭阀是供暖和给水等管路系统中常用的一种阀门,由阀体、阀芯、阀杆和相应的锁闭机构等组成,阀体为内部空腔结构且包括三通,分别为进水口、出水口和锁头接口,阀芯为球形阀芯,阀芯位于阀体的内部,阀芯与阀杆的内端连接,锁头通常位于阀体的外部,锁头与阀杆的外端连接,锁头可以为装在阀杆上的弹簧、棘爪和棘轮锁帽,调整阀芯位置后,把棘轮锁帽拧上,用户就不能自行开启,这样就可以实现对供暖和给水等系统一户一组的可控制通断,且非破坏性不能开启。磁性锁闭阀,就是依靠磁力的作用力达到控制锁闭阀内相应部件的开启和关闭,采用的是一种磁性锁,这种磁性锁闭阀一般用于一些重要的、特殊位置和功用的阀门上,防止阀门被任意开关使用,而且无任何空隙、防堵塞、防水、防腐、使用方便,深受当前供水、供暖、燃气、太阳能热水器等行业的青睐。现有技术中,很多锁闭阀在防盗性能方面都存在着较大的缺陷,特别是在受到外力作用时,会对锁闭阀相应部件造成破坏,例如难以防范一些普通工具(如管钳子)的破坏,从而不能有效的防止用户盗水盗暖等现象,另外,也存在着一定的安全隐患。
