Abstract

本实用新型涉及一种水泵用放气结构，属泵用放气结构制造领域。泵中设有放气管，放气螺堵与放气管内壁旋接，放气螺栓旋接在放气螺堵放气孔道内且可旋进、旋出。优点：一是泵中放气结构的设置，不仅能够可靠地将泵内的空气或含有空气的流体从放气结构中排出，而且能够有效地避免泵内液体对人体的伤害和对环境的污染；二是结构新颖、简单、可靠、成本低。

Description

泵用放气结构
技术领域：
本实用新型涉及一种水泵用放气结构，属泵用放气结构制造领域。
背景技术：
现有的泵用放气结构，在结构设计上，泵体中的放气结构采用螺栓堵头，排气时，直接将螺栓旋掉。其不足之处：当泵中的尚未完气体放出时，紧接着的便是液体，如果液体为高温液体或有毒或有害液体时，此时再将堵头旋接密封时，不可避免地烫伤或危害人们的身体健康，并且对环境产生污染。
发明内容：
设计目的：避免背景技术中的不足之处，设计一种能够将泵中积存的空气有效排出的泵用放气结构。
设计方案：为了实现上述设计目的，在结构设计上，在泵中设置一放气结构，该放气结构为泵用放气管侧向螺堵调控放气结构，即在泵用放气管的侧部开有放气气道，放气气道的通与不通采用螺堵控制，当旋接在放气管轴向内的螺堵旋紧时，螺堵的头将放气管口堵塞、螺堵的壁将放气气道口密封；当旋接在放气管轴向内的螺堵旋松时，螺堵的头离开放气管口、螺堵的壁与放气气道口呈间隙配合，泵头内的空气或气液体从泵中排出。其技术方案：泵头(1)中设有放气管(2)，放气螺堵(3)与放气管内壁旋接，放气螺栓(4)旋接在放气螺堵(3)的放气孔道内且可旋进、旋出。
本实用新型与背景技术相比，一是泵中放气结构的设置，不仅能够可靠地将泵内的空气或含有空气的流体从放气结构中排出，而且能够有效地避免泵内液体对人体的伤害和对环境的污染；二是结构新颖、简单、可靠、成本低。
附图说明：
图1是泵用放气结构的示意图。
具体实施方式：
实施例1：参照附图1。泵用放气结构，泵1采用现有技术制作且泵1的泵体上装有放气管2，放气管2的一端与泵头1腔体连通、一端与放气螺堵3旋接，放气螺栓4旋接在放气螺堵3的放气孔道内且可旋进、旋出。放气螺堵3侧部采用现有技术开有放气气道5。放气管2的管口小于螺堵3的堵头螺纹，螺堵3的堵头呈锥形。
需要理解到的是：上述实施例虽然对本实用新型作了比较详细的说明，但是这些说明只是对本实用新型说明性的，而不是对本实用新型的限制，任何不超出本实用新型实质精神内的发明创造，均落入本实用新型的保护范围内。
