Abstract

一种带有固紧弹簧的液化石油气调压器具有减 压阀体(5)、进气嘴(1)、弹簧圈(2)、螺管(3)、手轮 (4)、出气管(6)。由于在固紧螺管(3)前加设了弹簧 圈(2),使液化石油气减压阀与液化石油气钢瓶连接 时,提高了密封程度,同时旋进手轮(4)时也不必旋到 极限,大大减轻了手轮的拧紧力度,使安装调压器时 既省力又安全可靠。

Description

本实用新型涉及液化石油气调压器,特别适用于家用液化石油气钢瓶的调压连接。
现在家庭使用的液化石油气钢瓶与液化气调压器的连接是采用手轮上的螺管进行刚性连接,而旋紧手轮需十分用力,一般家庭妇女都会感到困难,如果拧紧力度不足,则容易造成漏气危及安全。
本实用新型的目的在于提供一种改进的液化石油气调压器,使液化石油气调压器与液化石油气钢瓶的连接方式在螺管刚性连接的同时又能实行弹性固紧,以达到减轻手轮拧紧力度,并提高气密程度。
本实用新型是这样实现的:在现有液化石油气调压器的高压进气嘴与固紧螺管之间加设一只相应直径和适当长度的弹簧圈。为使弹簧伸缩灵活,弹簧圈的内径不小于螺管的内径,其外径不大于螺管的外径。
本实用新型提供了一种改进的液化石油气调压器,由于在固紧螺管前加设了一只弹簧,使液化石油气调器与液化石油气钢瓶连接时,弹簧的伸张力可以提高进气嘴的接触密封力度,同时旋进手轮时也不必旋到极限,因此大大减轻了手轮的拧紧力度。
附图1是本实用新型实施例的外型图。
下面结合附图进一步描述其实施例。
带有固紧弹簧的液化石油气调压器,具有减压阀体(5)、高压进气嘴(1)、弹簧圈(2)、手轮(4)、与手轮(4)连体的螺管(3)、低压出气管(6)。设在进气嘴(1)与螺管(3)之间的弹簧圈(2)为本实用新型的改进部分。弹簧圈(2)的内径不小于螺管(3)的内径,其外径不大于螺管(3)的外径。最佳状态是弹簧圈(2)的长度为3-5圈,使螺管(3)留有比较宽松的前后活动余地。

Claims (1)
