工(gong)作原理：

Working principle:

  橡膠(jiāo)、金屬聯接器(qì)，主要由松套(tào)法蘭，橡膠、金(jin)屬波紋管😘等(deng)部件組成。管(guǎn)道系統因環(huán)境溫度或使(shǐ)用溫度産生(shēng)冷縮或膨脹(zhàng)時，所産生的(de)力和變形量(liang)、偏移角🌂度，聯(lián)接🍉器都能⛱️很(hen)好的補償。能(neng)吸收系🔞統振(zhen)動，降低☎️系統(tǒng)噪音✊，接頭兩(liǎng)端任意偏轉(zhuǎn)，能自由調節(jiē)軸向或橫向(xiang)位移等。

  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(huí)閥，主要由閥(fá)體、蝶闆、彈簧(huang)、絞軸及橡膠(jiao)圈等部件組(zǔ)成。介質由蝶(die)闆無簧面進(jìn)入，當兩半圓(yuán)形蝶闆🈚在受(shòu)介質壓力超(chāo)過彈簧支承(cheng)力後，使蝶闆(pan)自行打開，當(dāng)切斷前方介(jiè)質壓🔆力後，蝶(die)💋闆在彈☀️簧壓(ya)力及介質反(fan)壓力作用下(xia)迅速關閉。微(wei)阻緩閉止回(hui)閥，蝶闆在彈(dàn)簧壓力及介(jie)質反作用力(lì)下觸及✂️液壓(ya)微阻裝置，随(sui)着反作用力(lì)增大，蝶闆緩(huǎn)緩關閉。風道(dao)止回閥，蝶闆(pan)在重錘作用(yòng)力及介🚩質反(fǎn)作用力下迅(xun)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(zhuāng)及調試：

Installation and regulation

l  安裝(zhuang)前必需清潔(jié)閥門内腔，不(bú)允許有任何(hé)雜物和污垢(gou)附着。

l  法蘭式(shì)連接在安裝(zhuang)時，兩法蘭間(jian)需加密封墊(niàn)。對夾式🐉連接(jiē)在安🏃裝時，在(zài)法蘭與閥體(tǐ)連接處需加(jia)密封❗墊，然後(hòu)均勻擰緊螺(luo)栓。

l  止回閥安(an)裝時請注意(yì)流向（閥體上(shang)有箭頭标明(ming)）。

l  安裝時請調(diao)整使伸縮管(guan)伸出到伸縮(suō)量的1/2。使用一(yī)定期🎯限後，需(xu)更換密封圈(quān)。

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.
