The utility model provides a pressure resistant type wheel box, which comprises a type wheel box, a type wheel and a cover plate. The type wheel is located in the type wheel box, and the cover plate is fixed at the bottom of the type wheel box; the upper part of the type wheel box bulges outward to form an arc and forms a window at the top, and the external top surface of the type wheel box is provided with several reinforcing ribs; the pressure resistant type wheel provided by the utility model On the premise of not changing the overall dimension of the box, the top of the box is changed into an arc-shaped structure, and a reinforcing rib is set on the outside, which increases the pressure resistance and does not affect the normal installation of the movement; after the box is changed into an arc-shaped structure, the gap between the window and the wheel is reduced, reducing the occurrence of reading difficulties due to lack of liquid and fog in the wheel; after the box is changed into an arc-shaped inner body It can reduce the volume, reduce the water storage space, slow down the leakage speed of the wheel at high and low temperature, and improve the pressure resistance.
【技术实现步骤摘要】
一种耐压字轮盒
本技术涉及水表行业,尤其是指一种耐压字轮盒。
技术介绍
水表作为接入水管管路中的一种仪表,其要求具有一定的耐压性能,防止水压较高时水表发生爆裂。而且水表多安装在户外,在冰冻天气时表内的水容易发生结冰膨胀现象,在水表内部产生巨大压力,使水表字轮盒发生爆裂。目前字轮盒多为方形设计,其顶面与侧面的交界处容易发生应力集中,更易发生爆裂,致使水表报废、水管漏水,造成各种浪费与不便。
技术实现思路
(一)要解决的技术问题本技术目的在于提供一种具有较强的耐压性能的耐压字轮盒,为实现上述之目的,本技术采取如下技术方案:(二)技术方案一种耐压字轮盒,包括字轮盒、字轮、盖板,所述字轮位于所述字轮盒内,所述盖板固定在所述字轮盒底部;所述字轮盒上半部分向外凸起形成弧形并在顶部形成一视窗,所述字轮盒外部顶面设置有若干个加强筋。(三)有益效果本技术与现有技术相比具有明显的优点和有益效果,具体而言,在不改变整体外形尺寸的前提下将字轮盒顶部变为弧形结构,并在外侧设置了加强筋,在增加耐压性能的同时不影响机芯的正常安装;字轮盒变为弧形结构后,视窗与字轮之间的间隙减小,减少因字轮内因缺液起雾导致抄读困难的发生;字轮盒变为弧形后内部体积减小,减小了储水空间,可减慢高低温时字轮的漏液速度,提高耐压性。附图说明下面参照附图结合实施例对本技术作进一步的描述。图1是本技术纵向剖面示意图;图2是本技术的俯视图。附图标号说明:1、字轮 ...
