Production technology of pneumatic valve stem

pneumatic valve stem and ball joints and pneumatic valve stem and valve body contact should be an antistatic mechanism, prevent electrostatic agglomeration on the sphere. Pneumatic valve stem safety design should prevent was 'blown out' under the working pressure, pneumatic valve stem blow-out proof flange of the disposal of a circular ring, in order to reduce friction coefficient.
traditional pneumatic valve stem
the characteristics of the machining process. Traditional pneumatic valve stem thread USES the spiral, precision is inaccurate; And the traditional vulnerability without crumbs screw rolling rolling dies, easy deformation, distortion.
. Polished rod parts adopt grinding machine precision is not high, time consuming,
. Pour off parts adopt two clamping turn end seal, concentricity, pour sealing leakage easily.
. End parts adopt milling machine dial indexing, processing, slow process, takes a long time.
the characteristics of the pneumatic valve rod manufacturing process:
. New type of pneumatic valve rod thread with homemade extrusion, high intensity, precision.
. Threaded parts and parts of the polished rod of concentric, overcome the long plagued domestic thread rolling process easy distortion, vulnerability thread rolling die.
. Precision of the polished rod parts mirror effect, easy opening and closing, good seal.
. Pour off parts adopt numerical control technology a molding, high precision, pour sealing performance is good.
. Side parts forging forming technology on T slot, high efficiency and low cost.
. A complete set of pneumatic valve rod production technology reached the international advanced level.
in strong corrosion, volatile and harmful process conditions, once the pneumatic valve stem seal is broken, strong corrosion, volatile and harmful medium leakage from the pneumatic valve pneumatic control valve stem, to the serious consequences of surrounding environment and personal safety. The corrugated pipe pneumatic stem seal form is a way to solve the above problem. Generally speaking, stainless steel bellows. The special structure of pneumatic valve cover protection control pneumatic valve packing to avoid contact with fluid, once the corrugated pipe burst, stuffing box at the top of corrugated pipe structure can prevent corrugated pipe rupture failure which is caused by serious consequences. In engineering practice, the choice of the form of bellows seal should fully consider bellows sealed pressure rating would reduce with the temperature increases, the fluid solid particles cannot exist, and the longest of the corrugated pipe material circulation life, etc. In some process of medium corrosion resistance of stainless steel is strong corrosion, medium such as process of wet chlorine, wet chlorine contained traces of hydrochloric acid can be made of stainless steel bellows was quickly corrosion.
in the progress, the development of science and technology is becoming more and more quickly, a new type of pneumatic valve rod manufacturing technology to lower cost, improve efficiency, more in line with the requirements of modernization. In addition, corrugated pipe cut-off pneumatic valve manufacturer to prompt, pneumatic valve rod material selection is also an important task in the process of its production, hope don't ignore the important factors.
