Abstract

本实用新型由底部装有吸水管,侧面或底部装有与离心泵进水口相通的进水管的密闭容器及阀门、压力表组成。取代了公知技术中离心泵所必需的底阀,从而扩大了离心泵的工作范围,使之既能抽吸清水又能输送泥浆或含有粗颗粒和块状物质的流体,且只需灌一次引水。

Description

本实用新型属于离心泵无底阀装置。
在公知的技术中,底阀是离心泵不可缺少的部件。然而在某些场合却无法给离心泵安装底阀,或在输送某些含粗颗粒或块状物质的流体时,底阀往往关闭不严而失去装底阀的作用,致使离心泵无法正常工作。
本实用新型的目的在于提供一种能扩大离心泵使用范围,不受输送流体和安装场地的限制且安装使用方便的离心泵无底阀装置。
本实用新型的技术解决方案是:一种离心泵无底阀装置,包括现有离心泵的吸水管,其特殊之处在于吸水管一端能够进入一密闭容器内,且与密闭容器顶部内表面保持一适当距离,在密闭容器底部或侧面装有能与离心泵进水口相通的进水管。能与容器内相通的用于灌引水和排放空气的阀门和显示容器内压力的压力表装在容器顶部。
本实用新型的优点是:1.扩大了离心泵的工作范围,使之既能抽清水也能输送泥浆以及含粗颗粒或块状物质的流体。2.不管离心泵是连续还是间断工作,只需灌一次引水。3.结构简单,安装使用方便。4.较之安装底阀还有一定的节能作用。
附图为本实用新型的结构示意图。
下面结合附图对本实用新型的最佳实施例作进一步说明。与密闭容器〔1〕连接的吸水管〔2〕的一端能够从密闭容器底部进入,其上端部〔6〕不与密封容器顶部内表面接触,在密闭容器的底部或侧面装有进水管〔3〕与离心泵进水口相通,阀门〔5〕、压力表〔4〕装在密闭容器顶部。
在离心泵启动前,通过阀门向密闭容器内灌引水至容器内水位平齐或低于吸水管上端部。离心泵启动,随容器内预先所灌引水的排出而容器内出现真空,致使被输送的流体通过吸水管而吸入密闭容器,最后经过出水管进入离心泵排出。离心泵停止工作,密闭容器内始终能保持原有的水位,故离心泵再次启动,就不必再灌引水。本实用新型适用于各种离心泵。

Claims (3)
