工作(zuo)原(yuan)理(li)：

Working principle:

  橡膠、金屬(shu)聯接器，主(zhu)要由松套(tao)法蘭(lan)，橡膠(jiao)、金屬波紋(wen)管等(deng)部件(jian)組成。管道(dao)系(xi)統因環(huan)境溫度或使用溫度(du)産生冷縮(suo)或膨(peng)脹時(shi)，所産(chan)生的(de)力和變形(xing)量、偏(pian)移角(jiao)度，聯(lian)接器(qi)都能很好(hao)的補償。能(neng)吸收系統(tong)振動，降低(di)系統(tong)噪(zao)音(yin)，接頭(tou)兩端(duan)任意偏轉(zhuan)，能自由調(diao)節軸(zhou)向或橫向(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.

  止回閥(fa)，主要(yao)由閥(fa)體、蝶闆、彈(dan)簧、絞軸(zhou)及(ji)橡膠(jiao)圈等部件組成(cheng)。介質由蝶(die)闆無(wu)簧面進入，當兩(liang)半圓(yuan)形蝶闆在(zai)受介(jie)質壓力超(chao)過彈簧(huang)支(zhi)承力(li)後，使蝶(die)闆(pan)自行(hang)打開，當切(qie)斷前(qian)方介(jie)質壓力後(hou)，蝶闆在(zai)彈(dan)簧壓(ya)力及(ji)介質(zhi)反壓(ya)力作用(yong)下(xia)迅速(su)關閉(bi)。微阻緩閉(bi)止回(hui)閥，蝶(die)闆在(zai)彈簧壓力及介(jie)質反作用力下(xia)觸及液壓(ya)微阻(zu)裝置，随(sui)着(zhe)反作(zuo)用力(li)增(zeng)大，蝶闆(pan)緩緩關閉。風道止回(hui)閥，蝶闆在(zai)重錘(chui)作(zuo)用(yong)力及介質(zhi)反(fan)作(zuo)用力(li)下迅速關閥。

  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.

安裝及(ji)調試：

Installation and regulation

l  安裝(zhuang)前必(bi)需清(qing)潔閥(fa)門内腔，不允許(xu)有任何雜物和污垢附(fu)着。

l  法蘭(lan)式連接在(zai)安裝時，兩(liang)法蘭間需(xu)加密封墊。對夾(jia)式連接在(zai)安裝(zhuang)時，在法蘭與閥(fa)體連(lian)接(jie)處需加(jia)密封墊(nian)，然後均(jun)勻擰緊螺栓。

l  止(zhi)回閥安裝(zhuang)時請(qing)注意(yi)流向（閥體(ti)上有箭頭标明）。

l  安裝(zhuang)時(shi)請調整(zheng)使伸(shen)縮(suo)管(guan)伸出到伸縮量(liang)的1/2。使(shi)用一定(ding)期限後，需更(geng)換(huan)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.

訂貨須知：

Information for order

l  選用訂貨(huo)時(shi)，請(qing)參照(zhao)産品樣本(ben)注明産品(pin)規格(ge)、型号(hao)及技術參數（使(shi)用溫(wen)度，設(she)備工(gong)況、介(jie)質性(xing)質及工作(zuo)壓力等）。

l  表(biao)格中未(wei)列(lie)的規格、用于特(te)殊介(jie)質或其(qi)它特殊(shu)要求(qiu)，請(qing)與我公(gong)司銷(xiao)售(shou)部(bu)、技術(shu)部聯(lian)系，可為您(nin)另行(hang)設計制造。

l   Please indicate the type, model and technical parameter (using temperature, working condition of equipment and characteristic of medium etc) referring to the product sample when you place an order

l  If you have other special demand, need special medium or the spec that is not listed in the table, please contact with our department of market and technology. We can design and manufacture for you especially.
