二、進(jìn)口信號(hào)蝶閥產(chǎn)品特點(diǎn)：

1、小型輕便，容易拆裝及維修，并可以任意位置上安裝。

2、結(jié)構(gòu)簡單、緊湊，90°旋轉(zhuǎn)啟閉迅速。

3、操作扭矩小，省力輕巧。

4、達(dá)到完全密封，氣體試驗(yàn)泄漏為零。

5、選擇不同零部件材質(zhì)，可適用多種介質(zhì)。

6、流量特性趨于直線，調(diào)節(jié)性能好。

7、啟閉試驗(yàn)次數(shù)多達(dá)萬次，使用壽命長。

8、凡使用閘閥、止回閥（球形截流閥）">截止閥、旋塞閥、膠管閥及隔膜閥的管路，特別在高層建筑消防系統(tǒng)及需要顯示閥門開關(guān)狀態(tài)的管線系統(tǒng)上，均可用該閥替換。

1、 Small and light, easy to dismantle and repair, and can be installed in any position.

2. The structure is simple and compact, and the 90 ° rotary opening and closing are fast.

3. Small operating torque, light and labor-saving.

4. Achieve full sealing and zero gas test leakage.

5. Select different parts and materials, which can be applied to a variety of media.

6. The flow characteristics tend to be straight and the regulation performance is good.

7. The number of opening and closing tests is up to ten thousand, and the service life is long.

8. Where gate valve, check valve (globe shut-off valve) "> stop valve, cock valve, rubber pipe valve and diaphragm valve are used, the valve can be replaced, especially in the fire protection system of high-rise buildings and the pipeline system that needs to display the valve switch status.

三、進(jìn)口信號(hào)蝶閥工作原理：

1、信號(hào)蝶閥由蝸輪蝸桿傳動(dòng)裝置驅(qū)動(dòng)轉(zhuǎn)軸及蝶板旋轉(zhuǎn)實(shí)現(xiàn)啟閉和控制流量。

2、旋轉(zhuǎn)蝸輪蝸桿傳動(dòng)裝置手輪，使蝶板達(dá)到啟閉及調(diào)節(jié)流量的目的，手輪順時(shí)針方向旋轉(zhuǎn)為閥門關(guān)閉。

3、蝸輪蝸桿傳動(dòng)裝置箱體內(nèi)設(shè)置微動(dòng)開關(guān)有兩種形式：

a、在傳動(dòng)裝置箱體內(nèi)設(shè)有開向、關(guān)向兩個(gè)微動(dòng)開關(guān)，分別在閥門全開和關(guān)閉時(shí)動(dòng)作，接通控制室“閥開”“閥關(guān)”指示燈源，使之準(zhǔn)確顯示閥門開關(guān)狀態(tài)。

b、在傳動(dòng)裝置箱體內(nèi)設(shè)關(guān)向微動(dòng)開關(guān)（蝶板全關(guān)位置為0°），當(dāng)?shù)逵?/font>0°～40°位置時(shí)微動(dòng)開關(guān)支作，輸出閥門關(guān)閉信號(hào)，40°～90°位置時(shí)另一對(duì)常閉可輸出閥門打開信號(hào)?？烧{(diào)整壓觸微動(dòng)開關(guān)的凸輪，顯示蝶板所處的不同位置。

1. The signal butterfly valve is driven by the worm gear transmission device to rotate the shaft and butterfly plate to realize opening and closing and control the flow.

2. Rotate the hand wheel of the worm gear transmission device to open and close the butterfly plate and adjust the flow. Turn the hand wheel clockwise to close the valve.

3. There are two types of microswitches in worm gear box:

a. There are two microswitches in the transmission box, open and close, which act when the valve is fully open and closed respectively, and turn on the indicator light source of "valve open" and "valve close" in the control room, so as to accurately display the valve switch status.

b. The transmission box is equipped with a close microswitch (Butterfly fully closed position is 0 °). When the butterfly plate is from 0 ° - 40 ° position, the microswitch is supported to output the valve closing signal. When the butterfly plate is from 40 ° - 90 ° position, another pair of normally closed can output the valve opening signal. The cam of the press touch microswitch can be adjusted to display the different positions of the butterfly plate.

四、進(jìn)口信號(hào)蝶閥產(chǎn)品簡介：

德國《LOCKE》洛克進(jìn)口信號(hào)蝶閥是國際先進(jìn)技術(shù)而自行開發(fā)的中線型蝶閥，它具有結(jié)構(gòu)簡單，密封可靠，開啟輕便、壽命長、維護(hù)方便等優(yōu)點(diǎn)。故被廣泛地應(yīng)用于給排水、建筑消防等系統(tǒng)各種管道上，尤其在消防管路中。本信號(hào)閥可明白無誤的顯示出閥門開關(guān)狀態(tài)，具有直觀、清晰、可靠的反映出消防系統(tǒng)中的工作狀態(tài)，所以廣泛、大量的適用于消防系統(tǒng)中。

Locke imported signal butterfly valve from Germany is a self-developed middle line butterfly valve with international advanced technology. It has the advantages of simple structure, reliable sealing, light opening, long service life and convenient maintenance. Therefore, it is widely used in water supply and drainage, building fire protection and other systems, especially in the fire pipeline. The signal valve can clearly display the opening and closing state of the valve, which can directly, clearly and reliably reflect the working state of the fire fighting system, so it is widely and widely used in the fire fighting system.
