一种管道连通件 技术领域 TECHNICAL FIELD
本实用新型涉及管道连通件, 尤其是一种采用塑胶材质的管道连通件。 背景技术 The utility model relates to a pipe connecting piece, in particular to a pipe connecting piece made of plastic material. Background technique
目前所有各种塑胶材质的管材口径可以做到非常大的尺寸,但对于必须配 套的大口径管道连通件如三通、 四通均无法以先开钢质或铝质模具后再经射出 机来加工成型, 主要原因有: 大尺寸三通、 四通零件规格种类繁多, 且大尺寸 零件射出模具开模费用太高, 大容量射出机本身机器费用及配套费用投资太 大,再加上有些塑胶材料本身不耐长时间的高温烘烤,所以传统大尺寸的三通、 四通等各种规格尺寸的管道连通件均是以手工来加工, 即先将由塑胶管材制成 的管件主体部件中央锯一个 V形凹口, 同时将由塑胶管材制成的侧管底部也锯 一个与管件主体部件 V形开口相同尺寸的 V形凸口, 然后用同材质的焊条将以 上两个 V形接缝处焊接, 焊接完以后再用玻璃纤维片加特殊树脂 (FRP ) 将以 上悍接的 V形口及周边区域包覆起来。 以上传统手工制作成的大尺寸三通、 四 通管道连通件存在以下缺点: 本体与侧管因接合面积太小, 所以结合力不够牢 固, 抗拉性及抗压性均弱, 且密封效果不佳。 另外, FRP材质与管件主体及侧 管的塑胶材质热膨胀系数不同, 所以在长期积温状况下, 会互相脱离开, 同时 FRP的包覆外形非常不美观。 基于以上事实传统手工作大尺寸的塑胶管道连通 件三通、 四通均只能用于低压力及低温的管道系统。 At present, the caliber of all kinds of plastic materials can be very large, but for large-caliber pipe connections such as tees and crosses, it is impossible to open the steel or aluminum mold first and then pass the injection machine. The main reasons for processing and molding are: There are many types of large-size tee and four-way parts, and the injection mold opening cost of large-size parts is too high. The investment in the machine and supporting costs of the large-capacity injection machine is too large, plus some plastics. The material itself is not resistant to high-temperature baking for a long time, so traditional large-size tees, crosses and other pipe connections of various specifications are processed by hand, that is, the central part of the main body of the pipe made of plastic pipe is sawed first. A V-shaped notch. At the same time, the bottom of the side pipe made of plastic pipe is also sawed with a V-shaped protrusion of the same size as the V-shaped opening of the main body of the pipe. Then, the two V-shaped seams are welded with a welding electrode of the same material. After welding, use glass fiber sheet plus special resin (FRP) to cover the above-mentioned V-shaped mouth and surrounding area. The traditional hand-made large-size three-way and four-way pipe connecting parts have the following disadvantages: The joint area of the body and the side pipe is too small, so the bonding force is not strong enough, the tensile and compression resistance are weak, and the sealing effect is not good. good. In addition, the thermal expansion coefficient of the FRP material is different from that of the plastic material of the main body of the pipe and the side pipe. Therefore, under long-term accumulated temperature conditions, the FRP materials will be separated from each other. At the same time, the FRP coating appearance is very unsightly. Based on the above facts, traditional hand-worked large-sized plastic piping connection tees and crosses can only be used for low pressure and low temperature piping systems.
1988年 1月 19日递交的一份欧洲专利 (申请号为: 88200084. 7 ) 名称为 "管道连接件, 尤其是排水管道" , 此申请案公开了一种三通管道连通件的结 构, 是在管材制作的管件主体上做出一个以 90°直角向外翻转的小尺寸环状凸 起轴环, 再在此轴环上来开平行槽并加装膨胀物来卡住插入的侧管。 此种结构 存在着以下的缺点: 90°直角本身的抗压性就较弱,另外管件主体的凸出轴环与 侧管互相连接面积过小, 而且只靠膨胀物来连接, 与传统的橡胶活套式连接法 相似,结合力和密封效果均不佳,所以它们只能用于无压力的排水管路系统中,
而无法适应流体压力较大、 甚至是高温、 高压、 以及高密封要求的场合。 发明内容 A European patent (application number: 88200084. 7) filed on January 19, 1988, entitled "pipe connection, especially drainage pipe", this application discloses the structure of a three-way pipe connection, which is A small-sized ring-shaped convex collar turned outward at a right angle of 90 ° is made on the main body of the pipe made of the pipe. Then, a parallel groove is formed on the collar and an expansion is installed to clamp the inserted side pipe. This structure has the following shortcomings: The 90 ° right angle itself has weak compression resistance. In addition, the connecting area between the protruding collar and the side pipe of the main body of the pipe is too small, and it is only connected by the expansion, and it is connected with the traditional rubber. The looper connection method is similar, and the binding force and sealing effect are not good, so they can only be used in pressureless drainage pipeline systems. However, it cannot adapt to the occasions with large fluid pressure, even high temperature, high pressure, and high sealing requirements. Summary of the invention
