The utility model relates to a water-saving and explosion-proof angle valve, which comprises a main body of the angle valve, which is a non-metallic angle valve, and the main body of the angle valve is provided with a water inlet end, a water outlet end and a handwheel. The water inlet end is successively sleeved with a counterweight body and an inner sleeve, and the inner wall of the water inlet end is provided with a baffle, the inner end of the counterweight body is connected with the baffle, the inner end of the inner sleeve is sealed with the baffle, and the inner sleeve is The outer end is sealed with the outer end of the water inlet end, and the inner sleeve and the baffle are respectively provided with suitable water passages. The angular valve of the utility model can effectively reduce the volume of the chamber in the intake end of the angular valve through the configuration of the non-metallic body, the counterweight and the inner sleeve. When water freezes, the chamber has less water storage capacity, small volume expansion rate, effective explosion-proof function, and effective control of the overflow flow, which makes the outlet of the angular valve more mild and has less impact on other fittings such as connecting pipes. Effectively improve the utilization of water, but also protect other accessories, reduce the cost of use.

节水防爆角阀
本技术涉及角阀领域,特别是指一种节水防爆角阀。
技术介绍
角阀的应用十分广泛,目前多数的角阀主体的制备材料为金属材料,为控制成本和重量,角阀主体的壁厚较小,即角阀主体内的进水通道、出水通道及其它腔体的空间都非常大,这样的角阀存在着以下几个问题:第一,金属角阀容易溶出重金属元素,污染水源;第二,成本高,角阀在潮湿环境下也容易被腐蚀,使用寿命较短,使用成本也高;第三,过水量大,致使角阀的出水量也大,水的利用率较低;第四,在低温环境下,水结冰膨胀,金属材质形变量小,且内部容水量大,因而容易被冰撑破而爆裂。
技术实现思路
本技术提供一种节水防爆角阀,以解决现有的角阀低温易爆裂、易腐蚀、水利用率低等问题。本技术采用如下技术方案:节水防爆角阀,包括角阀主体;该角阀主体为非金属角阀主体,角阀主体配置有进水端、出水端和手轮,该进水端内依次套设有配重体和内套管,且配重体的内、外侧壁对应与内套管外壁、所述进水端内壁吻合连接。该进水端内壁设有隔挡板,配重体的内端与隔挡板抵接,内套管的内端与隔挡板密封连接,内套管的外端与进水端的外端密封连接,内套管与隔挡板分别设有相配适的过水通道。进一步改进地,上述内套管为非金属内套管,上述配重体为金属配重体。进一步改进地,上述内套管呈T字形,内套管与上述隔挡板之间配置有橡胶密封圈,内套管的外端与上述进水端的内壁通过胶液密封连接。进一步改进地,上述过水通道的孔口呈圆形、正三角形、正四边形或者正六边形。进一步改进地,上述过水通道的最大孔径为4~8mm。由上述对本技术结构的描述可知,和现有技术相比,本技术具有如下优点:本技术的角阀通过非金属 ...
