Abstract

Disclosed is a leak-proof flanged connecting pipe used for municipal construction, comprising a flanged connecting pipe main body (1), wherein a flange (3) is welded at one end of the main body (1), and two recessed grooves (5) are provided on an outer wall of the front part of the other end, a circular ring is filled inside the recessed grooves (5), the section of the recessed grooves (5) is rectangular, the circular rings are elastic circular rings (6), and the flange (3) uses a bolt for locking. Since the flanged connecting pipe is provided with recessed grooves and elastic circular rings filling the recessed grooves, when the flanged connecting pipe is inserted in a water supply steel pipe, the elastic circular rings and an inner wall of the water supply steel pipe are in close contact, serving the function of excellent leak-proofing.

Description

一种用于 nr政施工的防漏氷的法兰连接管  Anti-leakage flange connecting pipe for nr administration
技术领域 Technical field
本实用新型涉及一种法兰连接管，具体涉及一种用于市政施工的 防漏水的法兰连接管。  The utility model relates to a flange connecting pipe, in particular to a waterproof flange connecting pipe used for municipal construction.
背景技犬 Background dog
目前， 市政地下供水管很多为玻璃钢夹砂管， 玻璃钢夹砂管有结 构简单， 价格便宜， 密封性好等优点。 但是玻璃钢夹砂管承压能力较 差， 经不起过大的外部压力， 一旦地下玻璃钢夹砂管旁边要打下桥墩 等地基设施时，玻璃钢夹砂管就会因为承受不起这些设施所施加的压 力而导致爆破。因而很多地下供水管为玻璃钢夹砂管的地方一旦遇到 上述情况时， 玻璃钢夹砂管就要进行更换钢管， 而传统的钢管与玻璃 钢夹砂管的连接往往密封性不良， 容易发生漏水， 钢管与玻璃钢夹砂 管的挤压， 也会在一定程度上造成玻璃钢夹砂管的损坏。  At present, many municipal underground water supply pipes are made of FRP sand pipes, and the FRP sand pipes have the advantages of simple structure, low price and good sealing. However, the glass fiber reinforced plastic sand pipe has poor pressure bearing capacity and cannot withstand excessive external pressure. Once the underground glass fiber reinforced plastic sand pipe is to be laid down, such as bridge piers and other foundation facilities, the FRP sand pipe will not be able to withstand the application of these facilities. Pressure causes blasting. Therefore, in many places where the underground water supply pipe is a FRP sand pipe, the FRP sand pipe will be replaced with the steel pipe, and the connection between the traditional steel pipe and the FRP sand pipe is often poorly sealed, which is prone to water leakage. Extrusion with the FRP sand pipe will also cause damage to the FRP sand pipe to a certain extent.
实用新型内容 Utility model content
本实用新型的目的在于针对以上技术不足，提供一种用于市政施 工的防漏水的法兰连接管， 本实用新型针对现有传统施工方法的缺 陷， 可以有效地防止供水钢管发生漏水现象。  The purpose of the utility model is to provide a water-proof flange connecting pipe for municipal construction in view of the above technical deficiencies, and the utility model is directed to the defects of the existing conventional construction method, and can effectively prevent the water supply pipe from leaking.
本实用新型的技术方案如下：一种市政施工的防漏水的法兰连接 管， 包括法兰连接管本体， 所述本体一端焊接有法兰板， 另一端前部 外壁设有两道凹槽， 所述凹槽内填充有圆环；  The technical scheme of the utility model is as follows: a leak-proof flange connecting pipe of a municipal construction, comprising a flange connecting pipe body, a flange plate is welded to one end of the body, and two grooves are arranged on the outer wall of the front end of the other end. The groove is filled with a ring;
根据上述的技术方案， 其特征还在于， 所述凹槽剖面为矩形； 根据上述的技术方案， 其特征还在于， 所述圆环为弹性圆环； 根据上述的技术方案， 其特征还在于， 所述法兰用螺栓锁紧。 本实用新型设有凹槽和填充凹槽的弹性圆环，当法兰连接管插进 供水钢管时， 弹性圆环和供水钢管内壁紧密接触， 起到了很好的防泄 漏作用。 According to the above technical solution, the groove is a rectangular cross section; and according to the above technical solution, the ring is an elastic ring; According to the above technical solution, the flange is also bolted. The utility model is provided with a groove and an elastic ring filled with a groove. When the flange connecting pipe is inserted into the water supply steel pipe, the elastic ring and the inner wall of the water supply pipe are in close contact, which plays a good anti-leakage effect.
