工作原(yuán)理：

Working principle:

  橡膠、金屬聯接(jiē)器，主要由松套法(fǎ)蘭，橡膠、金屬波紋(wen)管等部👨‍❤️‍👨件組成。管(guǎn)道系統因環境溫(wēn)度或使用溫度🌍産(chǎn)生冷縮或膨脹時(shi)，所産生的力和變(biàn)形量、偏移角度，聯(lián)接器都能很好的(de)🔞補償。能吸收系統(tong)振動，降低系統噪(zào)音❄️，接頭兩端任意(yì)偏轉✍️，能自由調節(jiē)軸向或橫向位移(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，主要由(you)閥體、蝶闆、彈簧、絞(jiao)軸及橡膠圈等部(bù)件💞組成。介質由蝶(dié)闆無簧面進入，當(dāng)兩半圓形蝶闆在(zài)受介質壓力😍超過(guo)彈簧支承力後，使(shǐ)蝶闆自行打開，當(dāng)切斷前方介質壓(ya)力後，蝶闆在彈簧(huang)壓力及介質反壓(ya)力作用下迅速關(guān)閉。微阻緩閉止回(huí)閥，蝶闆在彈簧壓(yā)力及介質反作用(yong)力下觸及液壓微(wei)阻裝置，随着反作(zuò)用力增大，蝶闆緩(huan)緩關閉。風道止🔴回(hui)閥，蝶闆在重錘作(zuo)用♊力及介質反作(zuo)用力下迅速關閥(fa)。

  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.

安裝及調試：

Installation and regulation

l  安裝(zhuāng)前必需清潔閥門(mén)内腔，不允許有任(ren)何雜物和污垢附(fù)着。

l  法蘭式連接在(zai)安裝時，兩法蘭間(jian)需加密封墊。對夾(jia)式🔱連🔞接在安裝時(shi)，在法蘭與閥體連(lián)接處需加密封墊(nian)，然⚽後均勻擰緊螺(luó)栓。

l  止回閥安裝時(shí)請注意流向（閥體(tǐ)上有箭頭标明）。

l  安(an)裝時請調整使伸(shen)縮管伸出到伸縮(suo)量的1/2。使用一定期(qi)限後，需更換密封(feng)圈。

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：
