(一)预装

  ①卡套式管接头的预装的最重要的环节,直接影响到密封的可靠性。通常需要专用的预器。管径小的接头能够在台钳上进行预装。具体做法是,用一个接头作为母体,将螺母、卡套压紧到管子上可。主要有卡套式直通管接头、卡套式端直通接通头、卡套式三通管接头等型式。笔者发现,即使是同一厂家一批货,这几种接头体上锥形孔的深度往往不一样,成果就形成了走漏,而此疑问往往被忽视。正确的做法是,管子一端用什么样的接头体衔接,对应的衔接端则用一样类型的接头预装,这样能最大极限地防止呈现走漏疑问。

  ②管子端面应平齐。管子锯断后应在砂轮等东西上打磨平齐,而且去掉毛刺,清洁并用高压空气吹净后再运用。

  ③预装时,应尽量坚持管子与接头体的同轴度,若管子偏斜过大也会形成密封失效。

  ④预装力不宜太大使卡套的内刃刚好嵌入管子外壁,卡套不该有显着变形。在进行管路衔接时,再按规则的拧紧力装置。ф6-1卡套的拧紧力为64-1 15n、16фmmr 259n、ф18mm的为450n。若是在预装时卡套变形严峻,会失掉密封作用。

  (一) pre-installation

  (1)The most important part of the preassembly of the card sleeve type pipe joint, directly affects the reliability of the seal. Special presets are usually required. Smaller joints can be preassembled on a vise. The concrete way is, USES a joint as the mother body, presses the nut, the clamp sleeve to the pipe may. The main types are bayonet type through pipe joint, bayonet type end through connection head, bayonet type three-way pipe joint and so on. The author discovers, although be same manufacturer a batch of goods, the depth of conical hole on body of these a few kinds of joint is often different, the result formed leak, and this doubt often is ignored. The correct way is to use what kind of joint body to connect one end of the pipe, and the corresponding joint end is pre-installed with the same type of joint, so as to maximize the limit to prevent leakage.

  (2)The end of the pipe should be flush. After the pipe saw is broken, it shall be polished and leveled on the grinding wheel and other things, and the burr shall be removed, cleaned and blown clean with high-pressure air before use.

  (3)preinstallation, should try to adhere to the pipe and joint body coaxial, if the pipe deflection is too large will also form a seal failure.

  (4) preload force should not be too ambassador sleeve inside edge just embedded pipe wall, sleeve should not have significant deformation. When connecting the pipeline, tighten the device according to the rules. The tightening force of each sleeve with diameter of 6-1 is 64-1 15n, 16 diameter mmr259n, and diameter of 18mm is 450n. If the clamping sleeve deformation is severe during preinstallation, it will lose the sealing effect.

  (二)制止参加密封胶等填料。有人为了获得非常好密封作用,在卡套上涂上密封胶,成果密封胶被冲入液压体系中,形成液压元件阴尼孔阻塞等毛病。

  (二)Stop to participate in sealant packing. Someone in order to obtain a very good sealing effect, in the card sleeve coated with sealant, sealant results were flushed into the hydraulic system, the formation of hydraulic components Yin ni hole blocking problems.

  (三)衔接管路时,应使管子有满足的变形余量,防止使管子遭到拉伸力。

  (三)when connecting the pipe, the pipe shall have sufficient deformation allowance to prevent the pipe from being subjected to tensile force.

  (四)衔接管路时,应防止使其遭到侧向力,侧向力过大会形成密封不严。

  (四)when connecting the pipeline, it shall be prevented from being subjected to lateral force, which may lead to a loose seal.

  (五)衔接管路时,应一次性好,防止屡次拆开,不然也会使密封功能变差。卡套式管接头装置

  (五)when connecting the pipeline, it shall be good at one time to prevent repeated disconnection, or the sealing function will become poor. Bayonet coupling device

  (1)对需求酸洗的管子应先酸洗处置;

  (2)按需求长度用锯床或专用切管机等机具堵截管子,肯定不允许用溶断(如火焰切开)或砂轮切开;除掉管端表里圆毛刺、金属切屑及尘垢;除掉管接头的防锈剂及尘垢;一起还要保证管子圆度;

  (3)将螺母、卡套先后套入管子,卡套前端刃口(小径端)距管子口至少3mm,然后将管子刺进接头体内锥孔,顶到停止;

  (4)渐渐拧紧螺母,一起转变管子直至不动时,再拧紧螺母2/3~4
