Abstract

本实用新型公开了一种防冻哈夫节,包括壳体,所述壳体内部具有空腔,所述壳体的内壁上设有贴合有碳纤维发热膜,所述壳体的侧壁上设有电源盒。本实用新型结构简单、防止被冻裂,防止壳体内部结冰。

Description

防冻哈夫节
技术领域
本实用新型涉及一种防冻哈夫节。   
背景技术
    现有技术中,哈夫节在使用过程中,遇到天气寒冷的时候,哈夫节会被冻裂,且哈夫节的密封圈受到冷冻后,密封圈的使用寿命会降低。
实用新型内容
本实用新型目的是提供一种结构简单、防止被冻裂,防止壳体内部结冰的防冻哈夫节。
本实用新型解决技术问题提供如下方案:
一种防冻哈夫节,包括壳体,其特征在于:所述壳体内部具有空腔,所述壳体的内壁上设有贴合有碳纤维发热膜。
所述壳体的侧壁上设有电源盒。
本实用新型在哈夫节的壳体的内壁上贴合有一层碳纤维发热膜,这样通过对碳纤维发热膜进行通电加热,可以在寒冷的天气里,防止哈夫节边缘的密封圈被冻僵,导致密封圈失效,影响哈夫节的密封性能和使用寿命。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
参见附图,一种防冻哈夫节,包括壳体1,所述壳体1内部具有空腔2,所述壳体1的内壁上设有贴合有碳纤维发热膜3,所述壳体1的侧壁上设有电源盒4。

Claims (2)

1.一种防冻哈夫节,包括壳体,其特征在于:所述壳体内部具有空腔,所述壳体的内壁上设有贴合有碳纤维发热膜。
2.根据权利要求1所述防冻哈夫节,其特征在于:所述壳体的侧壁上设有电源盒。
