Detailed Product Description: | I. Introduction four-link insulation butterfly is our scientific research personnel, combined with years of phthalic anhydride production process and valve manufacturing experience to develop a new generation of insulation valves, the product is suitable for large-diameter, high-volume, low dropout voltage, and low leakage No leakage of the occasion, and has a high resistance to corrosion and high temperature performance, the valve open and close rapidly, regulating high precision, reliable sealing process for the production of pipes or cut off the media for the role of mediation phthalic anhydride, maleic anhydride, also can be used to control other gases, liquids and other media. Two. Working principle and structure features 1. Four-link insulation butterfly valve consists of two parts consisting of components and pneumatic actuators. Body parts from the body, jacket, valve plate, shaft, four-bar linkage, stuffing and other parts. Among them, valve, valve plates, steel plates welded to the jacket, lightweight structure. Executing agency for the double cylinder, rack and pinion, rotary output, install a smooth, inflatable fast, full travel speed, pneumatic actuators can be double-acting or single acting (spring return), determined by the user. The biggest advantage of the four-link eccentric flap valve is opened valve plate first shift, and the seat out, then rotate, so it is not easy to scratch the sealing surface, good and reliable sealing performance, and no wear and tear, plus four link eccentric mechanism, the role of the media when the valve is closed and thus more and more tightly, quickly disengaged when turned on, long service life. (2) Note: You must confirm the conversion when the handle is switched to the pneumatic tank ventilation shall be allowed to operate pneumatically operated butterfly valves when prohibited toggle lever when in manual or pneumatic tank tank pneumatically operated butterfly valve pneumatic four-link insulation (BD640HPPL) have with electrical valve positioner and handheld pneumatic devices. and insulation valve combination. Mechanical and electrical signal transmission locator device consists of a pneumatic cylinder piston connecting rod. Cabinet and other parts of the output shaft. Filter valves and other control components. When the manual operation handle switch to manual conversion square tank, turn the hand wheel opening and closing valves, pneumatic operation when the handle is switched to the square to convert pneumatic tank, pneumatic actuators and circuit and system gas supply is turned on, the valve positioner receives 4mA (20 mA) current signal is converted into an output air pressure of the compressed air into the cylinder at one end to the other end of the pushing movement of the piston, the piston valve to drive the output shaft to achieve quick opening and closing operation or the like adjusted by the connecting rod parts. While the position of the valve control signal conditioner output by the correct positioning of the device according to the pressure or flow variable feedback signal to send. For only required to open and close the pneumatic valve, just join a two-way solenoid valve in the control system, the command is completed under different commands to open and close the valve action 3. Electric four-link insulation butterfly (BD940HPPL) digital display overall regulation of electric equipment and insulation butterfly combination of the four-link digital display overall regulation of electric butterfly valve can also be the scene switches to control the valve opening and closing via 4-20mA current signal output on the cockpit seats. 4 four-link structure insulation Butterfly Standard length: GB/T12221-1989 long series PN: JB/T81-1994 PN0.25Mpa jacket heat pipe flange standards: JB/T79.1-1994 PN1.6Mpa Zibo Wei Hang Valve Co., Ltd. is a professional manufacturer of gas valve, steam insulation blowing gas valve which has obtained national patent, patent number:.. ZL2012200121356, and have dedicated blast furnace gas oven gas gas gas gas furnace dedicated butterfly, is preferred brand gas industry. "Wei Heng valve" special insulation bitumen production butterfly has obtained national patent, patent number ZL201220012132.2 "Wei Heng valve" digestion and absorption of foreign advanced technology, the use of advanced technology production of phthalic anhydride. Maleic anhydride special insulation valve has been many domestic manufacturers selection, maleic anhydride, phthalic anhydride enjoy a high reputation in the industry.
