Abstract

锁控式闸阀属于采暖供热管路用的器件。阀体经阀盖与外套连接,外套内外六方驱动杆装在内六方阀杆腔内。内六方阀杆由螺纹段、圆柱段、导柱腔、圆腔、六方腔、圆腔构成一体。外六方驱动杆由导柱、六方体、圆柱体、圆周槽、方台体构成一体,在方台体的一个面竖向开沟槽,圆柱体段装弹簧。在内六方阀杆圆柱段装密封件,螺纹段连接闸板。结构简单操作方便,供热控制、调节效果好利于热能管理。广泛适用于热力系统的采暖供热管路。

Description

锁控式闸阀
锁控式闸阀属于采暖供热管路用的器件。
目前采暖供热系统的散热器输入端普遍采用闸板式小口径阀门,用户可以私自开阀关阀调节流量,使供热失去平衡造成有的楼层温度高有的楼层温度低,影响总体系统供热效果。对于不缴纳供热费的用户也无法控制供热。
本发明的目的是:提供一种便于管理必须开封后再使用专用工具方能开关的新型锁控式闸阀。
本发明的技术方案是:阀体经阀盖与外套连接,外套内将外六方驱动杆装在内六方阀杆腔内构成简易离合器。内六方阀杆由螺纹段、圆柱段、导柱腔、圆腔、六方腔、圆腔构成一体。外六方驱动杆由导柱、六方体、圆柱体、圆周槽、方台体构成一体,在方台体的一个平面中心位置竖向开沟槽,圆柱体段装弹簧。在内六方阀杆圆柱段装两层密封垫和密封圈及密封固定套,螺纹段连接闸板。离合器分开闸板为锁住状态,外六方驱动杆在内六方阀杆的圆腔内可任意旋转,但不能带动阀杆及闸板动作。当需要闸阀动作开启或关闭时必须使用特制的钥匙来实现。具体说将手轮A内腔套在驱动杆的方台体上,内腔下端销钉对准沟槽落入圆周槽内旋转一下离开沟槽后向上提3-10mm,内六方与外六方咬合相当离合器结合,再将手轮B插在手轮A腔内,通过穿在手轮A轮沿内的弹簧销钉使A、B两个手轮咬合形成一体。转动手轮B可带动阀杆转动,闸板沿着螺纹段上下移动实现开启和关闭,当调节到所需的位置时取出手轮A、B外加封盖。
本发明结构简单操作方便,供热控制、调节效果好利于热能管理。广泛适用于热力系统的采暖供热管理。
附图:总体结构剖面示意图。
实施例:外套1密封固定套7阀盖8采用灰口铸铁HT20-40车制。阀体9选用普通阐板闸体。外六方驱动杆2采用中碳钢车制,铣方。内六方阀杆3采用中碳钢表面N化处理增加耐磨耐腐蚀性车制,插方。离和弹簧4采用65Mn回火处理。密封垫5为石棉板,密封圈6为橡胶圈。闸板10选购通用黄铜件。装配时将一个密封垫5装入外套内腔,离和弹簧4套在外六方驱动杆的圆柱体上一并装入内六方阀杆腔内,在其圆柱段装配密封固定套和密封圈及第二个密封垫。将此部件加润滑脂装在外套内腔,旋紧阀盖8再将闸板10旋在内六方阀杆的螺纹端,最后将阀体9连接在阀盖上。锁控闸阀全部装完后进行开启、关闭、耐压渗水实验合格后将外套与阀盖铆合。现场安装后在外套上端封盖。
