工作(zuo)原理(li)：

Working principle:

  橡膠(jiao)、金屬(shu)聯接(jie)器，主(zhu)要由(you)松套(tao)法蘭(lan)，橡膠(jiao)、金屬(shu)波紋(wen)管等(deng)♉部件(jian)組成(cheng)。管道(dao)系統(tong)因環(huan)境溫(wen)度或(huo)使用(yong)溫度(du)産生(sheng)冷縮(suo)或膨(peng)脹時(shi)，所産(chan)生的(de)力和(he)變形(xing)量、偏(pian)移角(jiao)度，聯(lian)接器(qi)都能(neng)很好(hao)的補(bu)償。能(neng)吸收(shou)系統(tong)振動(dong)，降低(di)系統(tong)噪音(yin)，接頭(tou)兩端(duan)任意(yi)偏轉(zhuan)，能自(zi)由調(diao)節軸(zhou)向或(huo)橫向(xiang)位移(yi)等。

  The rubber, metal connector is mainly made up of free flange, rubber and metal ripple pipe etc. The system pipe contracts or expands because of environment temperature or using temperature. The connector can compensate the force, distortion amount and excursion angle, which is made by contracting or expanding. It can absorb system quiver and reduce system noise. The joint ends can be deflected arbitrarily and adjust shaft freely.

  止(zhi)回閥(fa)，主要(yao)由閥(fa)體、蝶(die)闆、彈(dan)簧、絞(jiao)軸及(ji)橡膠(jiao)圈等(deng)部件(jian)組成(cheng)。介質(zhi)由蝶(die)闆無(wu)簧面(mian)進入(ru)，當兩(liang)半圓(yuan)形蝶(die)闆在(zai)受介(jie)質壓(ya)力超(chao)過🔞彈(dan)簧支(zhi)承力(li)後，使(shi)蝶闆(pan)自行(hang)打開(kai)，當切(qie)斷前(qian)方介(jie)質壓(ya)力後(hou)，蝶闆(pan)在彈(dan)簧壓(ya)力及(ji)介💋質(zhi)反壓(ya)力🐪作(zuo)用下(xia)迅❄️速(su)關閉(bi)。微阻(zu)緩閉(bi)止回(hui)閥，蝶(die)闆🏃🏻在(zai)彈簧(huang)壓力(li)✨及介(jie)質反(fan)作用(yong)力下(xia)觸及(ji)液壓(ya)微阻(zu)裝👨‍❤️‍👨置(zhi)，随着(zhe)反作(zuo)用🥵力(li)增大(da)，蝶闆(pan)緩緩(huan)關閉(bi)。風道(dao)止回(hui)閥，蝶(die)闆在(zai)重⚽錘(chui)作用(yong)力及(ji)介質(zhi)反作(zuo)用🔞力(li)下迅(xun)速關(guan)閥。

  The check valve is mainly made up of valve body, butterfly board, spring, wring shaft and rubber ring etc. the medium enter from butterfly board which is without spring. When medium pressure of the two round butterfly boards is beyond the spring bearing, the board will open itself. When cut off the medium pressure ahead, the board will close quickly on the effect of spring pressure and medium counterforce. The board of micro-block slow-close check valve touches the hydraulic micro-block device on the effect of spring pressure and medium anti-pressure. The board closes slowly as the counterforce increasing. The board of venting pipe check valve close quickly on the effect of hammer force and medium counterforce.

安(an)裝及(ji)調試(shi)：

Installation and regulation

l  安裝(zhuang)前必(bi)需清(qing)潔閥(fa)門内(nei)腔，不(bu)允許(xu)有任(ren)何雜(za)物和(he)污垢(gou)附着(zhe)。

l  法蘭(lan)式連(lian)接在(zai)安裝(zhuang)時，兩(liang)法蘭(lan)間需(xu)加密(mi)封墊(nian)。對夾(jia)式連(lian)接在(zai)安裝(zhuang)時，在(zai)法蘭(lan)與閥(fa)體連(lian)接處(chu)需加(jia)密封(feng)墊，然(ran)後均(jun)⛷️勻擰(ning)緊螺(luo)栓。

l  止(zhi)回閥(fa)安裝(zhuang)時請(qing)注意(yi)流向(xiang)（閥體(ti)上有(you)箭頭(tou)标明(ming)）。

l  安裝(zhuang)時請(qing)調整(zheng)使伸(shen)縮管(guan)伸出(chu)到伸(shen)縮量(liang)的1/2。使(shi)用一(yi)定期(qi)限👨‍❤️‍👨後(hou)，需更(geng)換密(mi)封圈(quan)。

l   The body must be cleaned before installed and there is no dirt and sundries clinging to the body.

l   Add seal cushion between two flanges of flange type connection or between the flange and valve body of dual clamp type connection, then screw down bolt when installs the valve.

l   Pay attention to the flow direction of check valve when install. There is arrow on the valve body.

l   Extend the pipe to the 1/2 of extension amount when install the extension pipe. Seal rings need to be exchanged after the steel extension pipe has been used for a period of time limit.

訂貨(huo)須知(zhi)：
