Cangzhou City, the production of hand wheel factory

 Blue Xin hand wheel manufacturer, the cash supply, quality and excellence. Valve hand wheel from raw materials, production, processing a range of services, specializing in the production of hand wheel factory wholesale blue Xin preferred blue-hsin valve hand wheel hand wheel manufacturer, specializing in the production of hand wheel, Good quality valve hand wheels, pulleys industry focusing on the development of production, Hotline: 15133797806 using valve hand wheels need to pay attention: 1, the valve temporary storage, should be placed in dry and ventilated room, to be used at both ends of the valve channel closure infarction, scheduled for processing the outer coating rust oil. 2, before the device should reflect on whether the use of check valves identified in line with the request to review whether the intact parts, fasteners could loosen. 3, before the valve means in the pipeline should be clear of debris (including greaseproof paper on both sides of the gate). 4, lifting the valve should be installed in the two flanges neck (or rings hole) use spreader lifting, lifting of the hand wheel is prohibited; 5. closed: clockwise rotation of the handwheel valves closed until the hand that position, place the upper hand wheel for an anti- Forward 1/2 to 1 turn (from the View window to see the stem guard should be in the following position). 6, closed: counterclockwise rotation of the handwheel closed valve, until your hands feel bit far (View from the guard should be in the upper part of the stem hole see status); 7, before using the valve sealant should be injected into the grease in the nozzles, each six months at most filling a; 8, sewage holes in the bottom of the valve, according to user needs walks media here dismantle drain valve; 9, are strictly prohibited as a throttle valve (except with throttle valve), and only allows It was fully open or fully closed condition; 10, is prohibited in the valve with a pressure valve repair or beat around; blue Xin handwheel plant a variety of valve handwheel stamping, punching hand wheel, valve hand wheels, hand pressed steel wheel, steel handwheel, valve handle, butterfly valve handle is how to rotate the handwheel: handwheel valves can be rotated, but the trip without any change, I ask this is caused by the what ah what are the specific reason or reasons for the positioning ah?? It is mechanical, pneumatic usual first pneumatic valve straight trip whether or rotary hand wheel must be used when expire, or easy to damage the hand wheel. Blue Xin handwheel Factory Main business: valve hand wheels, stamping handwheel, handwheel steel, stainless steel handwheel and the valve handle and other accessories. Blue Xin hand wheel factory production of various types of valve hand wheels, handles are available on-demand, invites all manufacturers of the Union, cooperation and win-win. The type of valve: 1, all kinds of classification methods valves: wide valves use a wide range of classification more. The total can be divided into two categories: the first category automatic valve: to rely on the media (liquid, gas) own capabilities and self-valve operation. Such as check valves, safety valves, control valves, steam traps, valves and the like. The second category actuated valves: With manual, electric, hydraulic, pneumatic valve operation to manipulate. A gate valve, globe valve, throttle, butterfly, ball, plug and so on. By Use: cut off valves, regulating valves, bypass valves, valve type, valve type; 2, according to the force point: he moves with the valve, the valve automatically applied. Company production, custom processing all kinds of hand wheel, which has a beautiful shape, bright color, feel fine, convenient and durable, are ready to use environmentally friendly products. Not only improves the overall appearance of the valves and value-added products, stamping handwheel Application: electric drive mechanism stamped on the hand wheel apparatus includes an adjustable torque or travel limit switch, travel limit switch is located in the valve fully open position hand wheel or all closed position, when there is an obstacle on the reverse transmission direction, can cut off the secondary motor control circuit power, torque switch must be installed by the manufacturer, and meet the maximum operating torque of the calculated value. Blue Xin hand wheel factory specializing in the production valve fittings, the main products are: a one-time use cold steel stamping, electrostatic spray after the completion of the hand wheel, handle; valve hand wheel products, including steel handwheel (iron hand wheel). Special supply massive high quality and large valve hand wheels, hand wheels, valve hand wheels, plastic handwheel, Wenzhou valve hand wheels, cast iron hand wheel, bakelite hand wheel, hand wheel stamping, stainless steel hand wheel, Botou hand wheel, cast iron handwheel valves . What is the valve hand wheel? Control valve to open or close the drive, and will be above the manual control lever or hand wheel, to control the valve switch. How to valve size handwheel selection: API6D requirement is not more than the handwheel opening force 360N. Hand wheel diameter is generally greater than the length of the structure is not. Handwheel filler valve leakage how to do: Cause: 1 filler choose wrong, corrosive media intolerance, impatience valve high pressure or vacuum, high or low temperature use; 2 packing installed wrong, there is a small generation of large, spiral wound. bad joints, tighten down other defects; 3. use of filler exceeds been aging, loss of elasticity 4. Stem accuracy is not high, curved, less corrosion, wear and other defects 5. packing laps, capping not pressed; 6. gland, bolts, and other components damaged, so the lid can not be pressed; 7 improper operation, excessive force, etc; 8. gland skew between the gland and stem the gap is too small or too big, causing valve. rod wear, packing damage. Check Category: 1.NRVZ Silent Check Valve Silent Check Valve 3.NRVR 2.NRVG Silent Check Valve 4.SFCV rubber flap check valve and the valve's sign of how the definition of requirements: General valve must be used and choose to use sign project, for manual valves, if the hand wheel size is large enough, then the hand wheel should be equipped with an arrow indicating the valve is closed or additional words "on" "off". 5.DDCV double disc check valve. What is the role of the valve handwheel is: on or off, or adjust the valve switch of {title}.
