Abstract

一种十字钢锁法兰阀,是在现有法兰阀阀体上盖侧部开有锁孔,其内装有十字钢锁及锁销,锁销与阀杆螺母上的定位孔相配合,十字形钥匙用于控制钢锁从而带动锁销开关来进行锁定或开启。这种带有钢锁的法兰阀即不改变原有阀门的各项性能,又能保证在锁体锁定钥匙管理者不在的情况下阀杆螺母(手柄)无法转动,阀杆不能带动阀片阀芯上下运动,因此具有防盗功能,解决了现有阀门在公共场所使用易丢失的问题。

Description

十字钢锁法兰阀
本实用新型法兰阀,特别是带有锁定装置的法兰阀。
与本实用新型最为接近的已有技术为一项名称为“十字钢锁球阀”的专利,该项目公开了一种十字钢锁球阀,是在阀体内由下至上依次装有带通孔的球体、阀杆、锁体及其内的锁芯,在锁体与锁芯之间装有锁簧及弹子,锁芯上开有截面为十字形的钥匙孔,这种球阀具有防盗功能,可广泛用于自来水、取暖设备及石油管道等中性流体的管路中控制管理使用,作为法兰阀具有防盗功能的结构目前还没出现。
本实用新型的任务是:克服现有技术的不足,设计一种结构简单、操作方便、使用寿命长的具有防盗功能的法兰阀。
本实用新型的任务是以如下方式实现的:十字钢锁法兰阀,是在现有法兰阀阀体上盖侧部开有锁孔,其内装有十字钢锁及锁销,锁销与阀杆螺母的定位孔相配合,十字形钥匙用于控制钢锁从而带动锁销开关。
本实用新型由于锁体安装在法兰阀上盖侧部这既不改变阀门的各项性能,又能保证在锁体锁定钥匙管理者不在的情况下阀杆螺母(手柄)无法转动,阀杆不能带动阀片阀芯上下运动,从而起到了防盗功能。
图1为本实用新型正面视图;
图2为图1的A-A剖视图;
图3为图2的B-B剖视图。
本实用新型的一个最佳实施例,如图,十字钢锁法兰阀包括阀体上盖9,在阀体上盖侧部开有锁孔,其内装有十字锁芯6和锁销7,锁销与阀杆螺母4上的定位孔8相配合进行定位,阀杆螺母4上的定位孔可以是沿圆周均布的2个以上,本实施例选用4个如图2、图3所示,与锁销7相配合使用的钥匙用于插入钥匙插入孔12进入十字形锁芯6内通过钥匙旋转来带动锁销7左右移动,当钥匙顺时针旋转时将锁销带动向左移动使锁处于开的状态,这时可搬动手轮1使调节阀杆2进行阀门的开启。当钥匙逆时针旋转带动锁销向右移动使锁处于关闭状态则阀门不能拧动。图中3为手轮紧固螺帽,5为阀杆螺母与手轮之间的固定键,10为阀盖与阀体联接孔,11为十字钢锁。

Claims (2)

1、一种十字钢锁法兰阀,它包括法兰阀,其特征在于:在法兰阀阀体盖侧部开有锁孔,其内装有十字钢锁及锁销,锁销可与阀杆螺母上的定位孔相配合,十字形钥匙用于控制钢锁开关。
2、如权利要求1所述的法兰阀,其特征在于:阀杆螺母上的定位孔数为2个以上。
