Signal butterfly valve for petroleum, chemical, food, medicine, paper, water and electricity, ships, water supply and drainage, smelting, energy and other systems on the pipeline. Used as a regulating and throttling device on a variety of corrosive, non-corrosive gas, liquid, semi-fluid and solid powder lines and vessels. Especially widely used in high-rise building fire control systems and other needs of the state show the valve on the pipeline system. First, the characteristics of the signal butterfly valve 1, small and lightweight, easy disassembly and maintenance, and can be installed anywhere. 2, the structure is simple, compact, 90 ° rotation quick opening and closing. 3, operating torque, light and labor-saving. 4, to achieve a complete seal, gas leak test to zero. 5, choose different parts and materials, applicable to a variety of media. 6, flow characteristics tend to be straight, good regulation. 7, up to ten thousand times the number of opening and closing test, long service life. 8, where the use of gate valve, check valve (ball valve) "> globe valve, plug valve, hose valve and diaphragm valve pipeline, especially in high-rise building fire protection system and the need to show the state of the valve switch system can be used The valve replacement. Second, the working principle of the signal butterfly valve 1, the signal butterfly valve driven by the worm gear shaft and disc rotation to achieve opening and closing and control flow. 2, rotating worm gear handwheel to enable the disc to open and close and The purpose of regulating the flow, the hand wheel clockwise to turn the valve closed. 3, worm gear box There are two forms of micro-switch box set up: a, in the transmission box with open to close the two micro Move the switch, respectively, when the valve is fully open and closed action, connected to the control room "valve open" "valve off" light source, so that it accurately shows the valve switch state b, in the transmission box set to the micro-movement Switch (butterfly plate closed position 0 °), when the butterfly plate from 0 ° ~ 40 ° position micro-switch support for the output valve closed signal, 40 ° ~ 90 ° position of the other normally closed Out of the valve to open the signal. Adjustable pressure contact micro-switch cam, showing the disc at different locations. Third, the signal butterfly valve worm gear adjustment and wiring methods 1, open the electrical switch box cover, according to the electrical control requirements of the cable Of the core wire received the corresponding terminal, and seal the cable inlet, at the same time the cable is fixed to prevent damage to the cable wiring when the external force affects 2, when the valve is in the "fully closed" position, clockwise turn the following off the cam, Is the cam just touch the micro switch (you can hear a click), and then tighten the screw on the cam fixed cam. 3, when the valve is in the "fully open" position, turn the opening cam counterclockwise, with the same Adjust the way to open the cam. 4, adjust the limit screw, when the valve in the "full close" or "fully open" position, the limit screw should not just top the worm gear limit plane, but should leave a certain Of the gap, and then tighten the lock nut on the limit screw 5, cover the electrical switch box cover, when the valve in the "full close" position, so that the opening indicator Needle points to the "0" scale on the dial, and tighten the screw to fix the pointer. 四, Notes on the use of signal butterfly valve 1, The butterfly valve can be installed on the pipeline at any position in space. 2, The installation position of butterfly valve should be guaranteed to be used, repaired and Easy to change 3, the installation of the butterfly valve can not consider the direction of pipeline flow, which allows two-way flow. 4, butterfly valve installed before installation should be stored in dry places, the valve plate slightly open 4 ° ~ 5 °. Installation should be carried out before the following: a, carefully check the use of the performance of the butterfly valve is consistent with the specifications b clean the chamber and the sealing surface, do not allow dirt adhesion, do not open and close the disc before cleaning c, check Whether the transmission device is connected with the flange on the butterfly valve reliably or not 6, When the butterfly valve is clamped in the pipeline, pay attention to whether the connection force is even and reliable. 7, the butterfly valve installed, the pipeline pressure test, the valve plate must be in the open position. 8, the butterfly valve installed, it should be regularly checked, the main items of its inspection are as follows: a, butterfly valve seat and O-ring damage. b, sealing performance of the valve plate sealing surface. c, butterfly valve repair assembly, opening and closing rotation may not have jamming phenomenon. d, butterfly valve repair assembly, the sealing performance test should be required. f, after each overhaul, the situation should be detailed records for future reference.
