自封由壬002 

      自封式管接頭安裝完畢自動(dòng)啟開，卸下時(shí)自動(dòng)閉合，杜絕了管體介質(zhì)流出污染環(huán)境，節(jié)省作業(yè)成本，防止沙塵進(jìn)入管體和設(shè)備中造成機(jī)械磨損，降低事故隱患，管接頭裝卸連接方便，減少勞動(dòng)強(qiáng)度，節(jié)省作業(yè)時(shí)間。所使用材料完全符合美國(guó) ASTM 和 AISI 標(biāo)準(zhǔn)，產(chǎn)品及零件全部采取了防腐處理。管接頭耐高壓、密封可靠、標(biāo)準(zhǔn)統(tǒng)一、通用互換性好。萬向自封式管接頭可根據(jù)連接方向自動(dòng)調(diào)節(jié)，管線排列整齊美觀，減少管線抗疲勞強(qiáng)度。
自封式管接頭可根據(jù)結(jié)構(gòu)不同分為兩大系列：
1、鋼珠式快速自封管接頭　

2、銷鍵插入式自封管接頭
　　The self-sealing pipe joint will open automatically after completion of installation and will close during disassembly, which completely eradicates environmental pollution arising from outflow of medium inside the pipe, saves the operation cost, prevents mechanical wear arising from dust inside the pipe and equipment and reduces the accident potentials. The pipe joint can be assembled, disassembled and connected easily, thus the labor intensity is reduced and the operation time is saved. Used materials completely conform to American ASTM and AISI standards. The preservative treatment is carried out on all products and parts. The pipe joints are characterized by high-pressure resistance, reliable seal, unified standard, good compatibility and interchangeability. The universal self-sealing pipe joint could carry out adjustment automatically as per the connection direction and the pipe lines are arranged orderly and beautifully, which reduce the fatigue resistance of the pipe line. The self-sealing pipe joints can be divided into two series as per structures:
　　1. Fast self-sealing steel ball pipe joint
　　2. Pin key plug-in self-sealing pipe joint.
