工(gōng)作原理：

working principle:

  橡膠(jiāo)、金屬(shǔ)聯接器(qì)，主(zhǔ)要由松套(tào)法蘭，橡膠、金(jīn)屬波紋(wén)管等部件(jiàn)組成(chéng)。管道系統因環(huán)境溫度或(huò)使(shǐ)用(yòng)溫度産生冷縮(suō)或膨脹時，所産(chǎn)生的力和(hé)變形(xíng)量、偏移角度，聯(lián)接器都能很好(hǎo)的補償。能吸收(shōu)系統振(zhèn)動，降低(dī)系統噪音(yīn)，接頭(tóu)兩端(duān)任意偏轉(zhuǎn)，能自由(yóu)調節(jiē)軸(zhóu)向或橫向位移(yí)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(fá)，主要由閥(fá)體(tǐ)、蝶闆、彈(dàn)簧(huáng)、絞(jiǎo)軸及橡膠(jiāo)圈等部件組成(chéng)。介質由蝶闆無(wú)簧面進(jìn)入，當兩(liǎng)半圓形蝶(dié)闆在(zài)受介質壓力超(chāo)過彈簧支(zhī)承力(lì)後，使蝶闆自行(háng)打開，當(dāng)切(qiē)斷前(qián)方介質壓力後(hòu)，蝶闆在彈(dàn)簧壓(yā)力及介質反(fǎn)壓力作(zuò)用(yòng)下迅速(sù)關閉(bì)。微(wēi)阻緩閉(bì)止回閥，蝶(dié)闆在(zài)彈簧壓力及介(jiè)質反作用(yòng)力下觸及(jí)液壓微阻(zǔ)裝置，随(suí)着反作(zuò)用力(lì)增大，蝶闆(pǎn)緩緩(huǎn)關(guān)閉。風道(dào)止回閥，蝶(dié)闆在(zài)重錘作用力及介質反作用力(lì)下迅(xùn)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.

安裝及調試：

installation and regulation

l  安裝(zhuāng)前必(bì)需清(qīng)潔閥(fá)門内腔，不允許(xǔ)有任何(hé)雜物和(hé)污垢(gòu)附着。

l  法蘭(lán)式連接在(zài)安裝(zhuāng)時，兩法蘭間需(xū)加密封墊。對夾式連(lián)接(jiē)在安裝(zhuāng)時，在法蘭(lán)與閥體連接處需加(jiā)密封(fēng)墊，然(rán)後(hòu)均(jun1)勻擰(nǐng)緊螺(luó)栓。

l  止(zhǐ)回閥(fá)安裝時請注意流向（閥體(tǐ)上有箭頭(tóu)标明）。

l  安裝時請調(diào)整(zhěng)使伸縮管(guǎn)伸出(chū)到伸縮(suō)量的1/2。使(shǐ)用一(yī)定(dìng)期(qī)限後(hòu)，需(xū)更(gèng)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.

訂貨須知：

information for order

l  選(xuǎn)用訂貨(huò)時，請(qǐng)參照(zhào)産品樣本注明産品規(guī)格、型号及技術(shù)參(cān)數（使(shǐ)用溫(wēn)度，設(shè)備工況、介質性(xìng)質及工作(zuò)壓力(lì)等）。

l  表(biǎo)格中(zhōng)未列(liè)的規格、用(yòng)于特(tè)殊介(jiè)質或其(qí)它特殊(shū)要求(qiú)，請與我公(gōng)司銷售(shòu)部(bù)、技術(shù)部聯(lián)系，可為您(nín)另(lìng)行設(shè)計制造(zào)。

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.
