工作原理：

working principle:

  橡膠、金屬聯接器，主(zhǔ)要由松套法蘭，橡膠、金(jīn)屬波紋(wén)管等部件組成。管(guǎn)道系統因環(huán)境溫(wēn)度或(huò)使用溫度産生(shēng)冷縮或膨脹時(shí)，所産生的力(lì)和變形(xíng)量、偏移角度，聯接器(qì)都能很好(hǎo)的補償。能(néng)吸收(shōu)系統振(zhèn)動，降低(dī)系統噪音，接頭(tóu)兩端任意(yì)偏轉(zhuǎn)，能自(zì)由調(diào)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(yào)由閥(fá)體、蝶闆、彈(dàn)簧、絞軸及橡膠(jiāo)圈等部件組成(chéng)。介質(zhì)由蝶(dié)闆無(wú)簧面進入，當兩半圓形蝶闆在受(shòu)介質壓力超(chāo)過彈簧支承力(lì)後，使(shǐ)蝶闆自行打開，當切斷前(qián)方介(jiè)質壓力後(hòu)，蝶闆在(zài)彈簧壓(yā)力及介(jiè)質反壓(yā)力作(zuò)用下(xià)迅速關閉(bì)。微阻緩閉(bì)止回閥，蝶闆在(zài)彈簧壓力及介(jiè)質反作用力下(xià)觸及(jí)液(yè)壓微阻(zǔ)裝置，随着反作用力(lì)增大(dà)，蝶闆緩緩關閉。風道止回(huí)閥(fá)，蝶闆在(zài)重錘(chuí)作用(yòng)力及(jí)介質反(fǎn)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(ān)裝及(jí)調試：

installation and regulation

l  安裝(zhuāng)前必(bì)需清潔(jié)閥(fá)門内(nèi)腔(qiāng)，不允許(xǔ)有任(rèn)何(hé)雜(zá)物和污垢附着。

l  法蘭(lán)式(shì)連接在安裝(zhuāng)時，兩法蘭間需加密封(fēng)墊(niàn)。對夾(jiá)式連接在安裝(zhuāng)時，在(zài)法蘭(lán)與閥體連接處(chù)需加(jiā)密封墊，然後均(jun1)勻擰緊螺(luó)栓。

l  止(zhǐ)回閥(fá)安裝(zhuāng)時請(qǐng)注意(yì)流向(xiàng)（閥體(tǐ)上(shàng)有箭(jiàn)頭标明(míng)）。

l  安裝時請調(diào)整(zhěng)使伸縮管伸出到伸(shēn)縮(suō)量的1/2。使(shǐ)用一定期(qī)限後(hòu)，需更換密封圈(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.

訂貨須知(zhī)：

information for order

l  選用訂貨(huò)時，請參照(zhào)産品樣本(běn)注明産品(pǐn)規格、型号及技術參數（使(shǐ)用溫(wēn)度，設(shè)備工(gōng)況、介質性(xìng)質及(jí)工作壓力等）。

l  表(biǎo)格中未列(liè)的規(guī)格、用于(yú)特(tè)殊介(jiè)質或其它特殊(shū)要求(qiú)，請(qǐng)與(yǔ)我公(gōng)司銷售部(bù)、技術(shù)部聯系，可為您另行設計制造。

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.
