工作原(yuán)理：

Working principle:

  橡膠(jiāo)、金屬聯(lian)接器，主(zhu)要由松(song)套法蘭(lán)，橡膠、金(jin)屬波紋(wén)♌管等部(bù)件組成(chéng)。管道系(xì)統因環(huán)境溫度(du)或使用(yòng)溫度💃産(chan)生冷縮(suo)或膨⛹🏻‍♀️脹(zhàng)時🏃🏻‍♂️，所産(chǎn)生的力(lì)和變形(xíng)量、偏移(yi)角度，聯(lian)接👉器都(dōu)能很好(hao)的補償(chang)。能📞吸收(shōu)系🧑🏾‍🤝‍🧑🏼統振(zhen)動，降低(dī)系統噪(zào)音，接頭(tou)兩端任(rèn)意偏轉(zhuan)，能自由(yóu)調節軸(zhóu)向或橫(héng)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(huí)閥，主要(yao)由閥體(tǐ)、蝶闆、彈(dan)簧、絞軸(zhóu)及橡膠(jiāo)圈等部(bu)件組成(chéng)。介質由(yóu)蝶闆無(wú)簧面進(jìn)入，當兩(liǎng)半圓形(xing)蝶闆在(zai)受介質(zhì)壓力超(chāo)過彈簧(huang)支承力(li)後，使蝶(dié)闆自行(hang)打開，當(dāng)切斷前(qián)方介質(zhi)壓力後(hòu)，蝶闆在(zai)彈簧壓(yā)力及介(jie)質反壓(ya)力作用(yòng)下迅速(su)關閉。微(wēi)♻️阻緩閉(bi)止回閥(fa)，蝶闆👌在(zai)彈簧壓(ya)力及介(jie)質反作(zuò)用力下(xia)觸及液(ye)壓微阻(zǔ)裝置，随(suí)着反作(zuò)用🌂力增(zeng)大，蝶闆(pǎn)緩緩關(guān)閉。風道(dào)止回閥(fá)🤞，蝶闆在(zai)重錘作(zuo)用✏️力及(jí)介質反(fan)作用力(li)下迅速(su)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)裝及調(diao)試：

Installation and regulation

l  安裝(zhuāng)前必需(xū)清潔閥(fa)門内腔(qiang)，不允許(xu)有任何(he)雜物和(he)污垢附(fù)着。

l  法蘭(lán)式連接(jie)在安裝(zhuang)時，兩法(fǎ)蘭間需(xū)加密封(feng)墊。對夾(jiá)式連接(jie)在安裝(zhuāng)時，在法(fa)蘭與閥(fá)體連接(jiē)處需加(jia)密封🔴墊(niàn)，然後均(jun)勻擰緊(jin)螺💃🏻栓。

l  止(zhǐ)回閥安(ān)裝時請(qǐng)注意流(liu)向（閥體(ti)上有箭(jian)頭标明(ming)）。

l  安裝時(shí)請調整(zhěng)使伸縮(suo)管伸出(chu)到伸縮(suō)量的1/2。使(shi)用一定(ding)期限後(hou)，需更換(huàn)密封圈(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(xu)知：

Information for order

l  選用(yong)訂貨時(shi)，請參照(zhao)産品樣(yang)本注明(míng)産品規(gui)格、型号(hào)及技術(shù)參💜數🌈（使(shi)用溫度(du)，設備工(gōng)況、介質(zhì)性質及(ji)工作💋壓(yā)力🐕等）。
