Abstract

本实用新型是连接管路的一种大口径卫生管接头,它主要是由接头主体,外螺母,卡环及密封圈组成,它的结构特点是卡环与管子接触的内圆面有锯形齿,齿向朝里倾斜,推顶管子向里压紧,增强拉脱强度,省去内衬,避免内径变小,减少水流阻力,提高接头使用寿命,该实用新型结构简单,容易装卸。

Description

大口径卫生管接头
本实用新型涉及连接冷水管、热水管管路的一种大口径卫生管接头。
现有的冷、热水(介质)管大口径管接头与管子连接处都在管径内设置有内衬,以保证密封性能和增强拉脱强度,由此而带来的弊端是使管路在连接处的通径变小,水流阻力增大,尤其是大口径的管路会出现漏水,另外,管接头的另件多,结构比较复杂,反修率增多,影响使用寿命。
针对现有大口径管接头存在的不足之处,本实用新型提供一种适用于直通接头,弯通接头,三通接头,四通接头,堵头和异径接头连接,无内衬的管接头。
本实用新型的技术构思方案如下:它主要包括有接头主体,外螺母,卡环及密封圈,管子外壁同接头主体内壁之间设置有卡环和密封圈,外螺母紧固接头主体与管子的连接,外螺母内腔端面成斜面,它的内园端面与卡环端面外园接触,接头主体上制有弹性衬塑,它的技术特点是卡环与管子接触的内园面有锯形齿,齿向朝内倾斜。
本实用新型的积极效果在于:卡环内园面呈锯齿形,齿向朝接头主体里倾斜,顶连管子,提高拉脱强度,省去内衬,克服连接处内径变小,水流阻力大的弊病,减少维修,外螺母端面内园和卡环外园端面接合,减少平面摩擦阻力,使操作省力,减轻相临接头出现的松动,接头主体的弹性衬塑,能提高管子连接端的密封性能。
以下,根据附图,结合实施例,对本实用新型的技术内容进一步加以说明。
图1是本实用新型直通接头结构视图。
图2是堵头结构视图。
图1所示,连接的两根管子1相对顶接在接头主体7的弹性衬塑6,在接头主体7内壁与管子1外壁相接处置有卡环3,垫片4,密封圈5,其排列是密封圈5在下面,垫片4在中间,卡环3在上面。卡环3的内园面设置有锯形齿,其齿向是向内倾斜,成30°~65°度角,外螺母2端面向外侧呈斜面,同卡环3端面外园接触,旋动与接头主体7螺纹连接的外螺母2,推压卡环3向里移动,通过卡环3的斜齿把管子1往里推,使两连接管子1端面同接头主体7弹性衬塑6紧压。
图2是本实用新型的另一实施例,接头主体7及弹性衬塑6一端面封口,呈凹字形,管子端口***接头主体7,通过外螺母使其顶压在衬塑6封口端面。
