Abstract

本实用新型涉及一种自闭式水阀门,包括阀门壳 体、手柄,其特征在于阀门连杆上设有弹性发条,阀门 连杆与阀门采用螺纹传动连接,本实用新型结构简 单,只对现有水阀门作较小的改动就能达到自动关闭 的效果,同时还能延长水封的使用寿命,提高阀门的 封闭性。

Description

本实用新型涉及一种水阀门,尤其是一种自闭式水阀门。
现有水阀门,尤其是家庭用水阀门,一但打开后,须人为关闭,使用不够方便,有时开启后,如不及时关闭,水就会溢出,另外,现有水阀门,多数在开启时,阀门连杆及阀门均同时上下移动,水封极易损坏,造成阀门连杆与壳体接触处漏水。
本实用新型的目的在于提供一种开启后能够自动关闭,且阀门连杆处封闭性能好的自闭式水阀门。
本实用新型包括阀门壳体、手柄,其特征在于阀门连杆上设有弹性发条,阀门连杆与阀门采用螺纹传动连接,连杆上有传动外螺纹,阀门上部有相应的内螺纹。
为了能在较长时间用水时,使阀门定位,在阀门连杆上还设有一个定位棘轮机构。
本实用新型结构简单,只对现有水阀门作较小的改动就能达到自动关闭的效果。同时还能延长水封的使用寿命,提高阀门的封闭性。
以下结合附图对本实用新型及实施例作详述。
图1是本实用新型一个实施例的剖视图。
实施例:
参照附图,本实用新型包括手柄(1),阀门壳体(7),在阀门连杆(2)上设有弹性发条(5),阀门连杆(2)与阀门(6)之间采用螺纹传动连接,连杆(2)上有传动外螺纹,阀门(6)上有与之相应的内螺纹,为能在需较长时间用水情况下使用,在阀门连杆上还设有一组定位棘轮机构(3、4)。在需较长时间用水时,可在开启阀门后,将棘爪(4)推入棘轮(3)的棘齿内,阀门就可定位,关闭时只需将棘爪(4)归位,阀门即可自动关闭。

Claims (2)

1、一种自闭式水阀门,包括阀门壳体、手柄,其特征在于阀门连杆上设有弹性发条,阀门连杆与阀门采用螺纹传动连接,连杆上有传动外螺纹,阀门上部有相应的内螺纹。
2、如权利要求1所述的自闭式水阀门,其特征在于阀门连杆上设有一个定位棘轮机构。
