Novel low temperature stop valve

新型低温截止阀

Abstract

The utility model relates to a novel low temperature stop valve, including valve rod and valve clack, the mounting groove that is used for connecting the valve rod is offered at the upper end of valve clack middle part, and at least one ball groove has been offered to the lower extreme lateral wall of valve rod, the ball inslot sets up the steel ball, and the degree of depth in ball groove is less than the steel ball diameter, at least one screw hole has been seted up to the lateral wall of valve clack, and the screw hole communicates with each other with the mounting groove, is provided with stop screw in the screw hole, when the tip inserted in the mounting groove of valve clack under the valve rod, the ball groove lay in same height with the screw hole on the valve clack, the ball inslot is filled in through the screw hole to the steel ball, restricts at the ball inslot in the stop screw screw in screw hole and with the steel ball. The design and processing size of messenger's valve clack can effectually reduce, reduces the quantity of part, and the valve clack is connected by the steel ball with the valve rod for cooperate more flexibility and joint strength also to promote greatly.
本实用新型涉及一种新型低温截止阀,包括阀杆和阀瓣,阀瓣的上端中部开设用于连接阀杆的安装槽,阀杆的下端侧壁开设有至少一个球槽,所述球槽内设置钢球,球槽的深度小于钢球直径;阀瓣的侧壁开设有至少一个螺钉孔,螺钉孔与安装槽相通,螺钉孔内设置有限位螺钉;当阀杆下端部插入阀瓣的安装槽内时,球槽与螺钉孔在阀瓣上位于同一高度;钢球经螺钉孔塞入球槽内,限位螺钉旋入螺钉孔内并将钢球限制在球槽内。使的阀瓣的设计加工尺寸可以有效的减小,减少零件的数量,阀瓣与阀杆靠钢珠连接,使得配合更灵活性且连接强度也大大提升。
