The utility model provides a compact self cleaning cut-off valve, including the valve body, which includes the inlet channel and the outlet channel. The connecting part is equipped with a valve seat, the top of the seat is fixed with the brush; the lift sleeve is fixed with the valve valve with the seat seal, and the lifting sleeve is connected with the body thread; the cover of the valve is connected with the valve body; the cover of the valve is connected with the valve body; the lid of the valve is connected with the body thread; the cover of the valve is connected with the body thread; the cover of the valve is connected with the body thread; the cover of the valve is connected with the body thread; the cover of the valve is connected with the body thread; the cover of the valve is connected with the body thread; the cover of the valve is connected with the body thread; the cover of the valve is connected with the body thread; the cover of the valve is connected with the body of the valve; It is firmly attached to the upper end of the valve body; the central part of the valve cover is connected with a stem, and the lower end of the stem is inserted into the lifting jacket and connected to the drive; the sealing pad is between the valve cover and the valve body; when the lifting sleeve is at the highest position, the upper end of the cushion is tightly sealed. The compact self cleaning cut-off valve of the utility model can clean the surface of the conical sealing surface on the valve disc in the process of closing and opening the utility model. Because the seal between the lifting sleeve and the seal is a radial seal structure, it can make the structure of the stem part more compact and compact compared with the existing technology. It is suitable for small space installation.

一种结构紧凑的自清洁截止阀
本技术属于阀门
,尤其是涉及一种截止阀。
技术介绍
截止阀是使用最为广泛的阀门之一,其具有制造成本低,维修方便等优点。然而现有的截止阀在使用过程中,液体介质所携带的杂质会粘附在阀瓣的密封面上,造成阀瓣与阀体的密封面产生缝隙,破坏密封效果。此外,现有的阀杆密封结构由于采用轴向密封的方式,使得截止阀的整体高度较高,不能适用于空间较小的安装环境。
技术实现思路
有鉴于此,本技术旨在提出一种结构紧凑的自清洁截止阀,以解决现有技术中,由于阀瓣上粘附杂物从而造成截止阀失效及截止阀整体高度较高的问题。为达到上述目的,本技术的技术方案是这样实现的:一种结构紧凑的自清洁截止阀,包括阀体,其内部包括进水流道和出水流道,两者连通的部分设有阀座,阀座的顶端固接有刷毛;升降套,其底部固接有与阀座密封配合的阀瓣,升降套与阀体螺纹联接;阀盖,其固接于阀体的上端;阀盖的中部转动连接有阀杆,阀杆的下端伸入升降套内,且与之传动连接;密封垫,其至于阀盖与阀体之间;当升降套位于最高位置时,其上端压紧密封垫。进一步,所述阀座的顶端设有清洁环,所述刷毛周圈固接于清洁环的内圆侧壁上。进一步,所述刷毛位于所述清洁环内圆侧壁的上部,且清洁环的内径大于所述阀座密封面的最大直径。进一步,所述阀座与阀瓣之间的密封结构为锥面密封结构。进一步,所述出水流道与阀体的上端开口之间设有与阀体一体成型的密封挡板,密封挡板的中心位置设有上下贯通的螺纹孔,所述升降套通过螺纹孔与密封挡板螺纹联接。进一步,所述密封垫嵌装于所述上端开口处,且密封垫的顶端伸出所述阀体。进一步,所述阀杆的下部横截面为多边形,且 ...
