消防信号蝶阀

Fire Fighting Signal butterfly valve

●简介  Brief

本蝶阀适用在石油、化工、食品、医药、造纸、水电、船舶、给排水、冶炼、能源等系统管路上。可在多种腐蚀性、非腐蚀性的气体、液体、半流体以及固体粉末管线和容器上作为调节和截流设备使用。特别广泛适用于高层建筑消防系统及其它需要显示阀门开关状态的管线系统上。

This butterfly valve is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papermaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc the pipe route. Can regard on gas, liquid, semifluid as well as sloid powder pipes and power lines and the container of many kinds of corrosive ness and non-corrosiveness adjusts and dams ariver the equipment use. Especially extensively being suitable in high layer of building fire prctection system reaches other to show in the pipes and power lines system of valve switch state.

5,  Long service life. Standing the test of tens of thousands opening/closing operations.

6,  Bubbles-tight sealing with no leakage under the pressure test.

7,  Wide selection of materials, app;icable for various mdeilum.

8,  Gate valve, globe valve, cock, glue pipe valve and diaphragm valve altogether, especially reaching and need show in the pipes and power lines system of valve switch state at high layer of building fire protection system, all available this valve is replaced.

●工作原理  The Work Principle

1、本信号蝶阀由涡轮蜗杆传动装置驱动轴及蝶板旋转实现启闭和控制流量。

2、旋转涡轮蜗杆传动装置手轮，使蝶板达到启闭及调节流量的目的，手轮顺时针方向旋转为阀门关闭。

3、涡轮蜗杆传动装置箱体内设置微动开关有两种型式：

（1）在传动装置箱体内设有开向、关向两个微动开关，分别在阀门全开和关闭时动作，接通控制室“阀开”“阀关”指示灯电源，使之准确显示阀门开关状态。

（2）在传动装置箱体内只设关向微动开关（蝶板全关闭位置为0°）。当蝶板由0~40°位置时微动开关动作、输出阀门关闭信号，40~90°位置时另一对常闭触点可输出阀门打开信号。可调整压触微动开关的凸轮，显示蝶板所处的不同位置。

1,  This signal butterfly valve is by the pot wheel worm-drive device drive tuming axle and the butterfly board revolving realizes opening and close and controls the volume of flow.

2,  Revolving the worm gear worm-drive device handwheel, making butterfly board achieve the purpose opening and close and adjusts the volume of flow, that the handwheel clockwise revolves closes down for the valve.

2,  The worm gearworm-drive device chest is set up the microswitch inside the body andis had two kinds of versions:

(1)   At the gearing chest has out inside the body to and the pass to two microswitchs. Two switches move respectively at the valve standard-sized sheet with when cutting out, the pilot lamp power supply in the connection control room “valve leaves” “valve pass”, mades accurately shows the valve switch state.

(2)   In the gearing chest body. The signalis closed down by the export valve to the microswitch action when the butterfly biard is by 0~40°seat, and another can be sended out the valve and opening the signal to often closing the contact during 40~90°seat. Can adjust the cam that the pressure was touches the microswitch, and show the different seats of buttfefly board place.
