Abstract

This utility model relates to a connecting device of large and medium caliber pipe element, consisted of connecting piece 5, connecting bolt 4, connecting nut 3 and sealing packing ring 6; the connecting piece 5 is provided with one step shape flange piece fastener 2 which is matched with this connecting piece, and the connecting main body is consisted of bolt 4, nut 3, step shape flange piece fastener 2 and connecting piece 5; meanwhile, the cavity of this step shape flange fastener 2 is provided with one cone shape tooth clamp 8 and washer 7; the sealing component between pipe body 1 and connecting piece 5 is consisted of cone shape tooth clamp 8, washer 7 and sealing packing ring 6 at the upper part of washer 7; the height h for the cavity of step shape flange fastener 2 should be less than the height H of cone shape tooth clamp 8.Comparing with the pipe element connecting device which is universally used for the moment, the advantages are that the connection is fast, structure is simple; moreover, the joint and pipe element without connection is covered by connecting screw thread which can reduce the cost of manufacture.
本实用新型涉及一种大中口径管件的连接装置,由连接件5、连接螺栓4、连接螺母3、密封填料圈6组成,其特征在于:所述的连接件5上设有一与该连接件配套的台阶状法兰片紧固件2,并由螺栓4、螺母3、台阶状法兰片紧固件2与连接件5组成连接主体;同时在该台阶状法兰紧固件2的凹陷处置有一锥体状齿卡8及垫圈7,由锥体状齿卡8、垫圈7及设于垫圈7上部的密封垫料圈6组成管体1与连接件5之间密封组件;所述台阶状法兰紧固件2的凹陷处的高度h应小于锥体状齿卡8的高度H。与目前普遍使用的管件连接机构相比较,其优点是连接牢固,结构更为简单,而且由于不用参予连接的接头和管件上套制连接丝扣,还可以降低制造成本。
