New type of pneumatic technology and pneumatic valve stem rod type

the new pneumatic valve stem process
stem, English name valve stem, is one of the important parts, pneumatic valve accessories used in pneumatic valves, actuators or handle, directly drive the pneumatic valve core moving or rotating below, in order to realize the pneumatic valve switch or adjustment.
pneumatic valve stem is not only in the process of pneumatic valve opening and closing of the force and movement, and is a seal. At the same time, it is under the impact of the media and corrosion, and also with packing friction. So when choosing pneumatic valve stem material, must ensure that its under the specified temperature of sufficient strength, good impact toughness, abrasion resistance, corrosion resistance. Pneumatic valve stem is wearing parts, still should be paid attention to when choose material machining and heat treatment performance. Pneumatic valve lever type


pneumatic valve stem types are: stop pneumatic valve pneumatic valve stem, pneumatic valve pneumatic brake valve rod series, pneumatic ball valve, pneumatic valve stem, pneumatic valve pneumatic butterfly valve rod, security pneumatic valve pneumatic pneumatic valve pneumatic valve stem, valve stem, oilfield forging steel pneumatic valve pneumatic valve stem, Marine pneumatic valve pneumatic pneumatic valve rod, stainless steel stem, soft seal pneumatic valve rod series pneumatic valve stem, large pneumatic valve rod, copper and so on a series of pneumatic valve pneumatic valve stem.

pneumatic stem nut to match the pneumatic valve rod with threads, direct pneumatic valve rod under axial force, friction and brand pneumatic valve parts, such as stents. Pneumatic stem nut, therefore, besides must have certain strength, also with small friction coefficient, no rust, no and properties, such as pneumatic valve rod killed.

at present about the pneumatic valve rod production enterprises, pneumatic valve rod company do big, gradually increasing competition in the industry.

the new pneumatic valve rod processing technology is made of homemade forging cold extrusion forming technology, high thread strength, accuracy, threaded parts and parts of the polished rod concentricity, overcomes the traditional chipless thread rolling easy to distort, easy to deformation, vulnerable thread rolling die, problems such as polished rod position precision mirror effect after using proprietary technology, and the opening and closing more relaxed, sealed performance is good, and the key parts of pneumatic valve stem fall off using a CNC forming, tensile and torsion, from several aspects to ensure the quality of the product components.

is a pneumatic valve stem is made of homemade forging cold extrusion forming, threaded with high intensity, precision accurate, completely solve the original traditional pneumatic valve stem thread USES the screw, screw thread accuracy is not allowed.
2 is threaded parts and parts of the polished rod concentricity, overcome the long plagued domestic thread rolling process, using traditional chipless thread rolling easy to distort, easy to deformation, vulnerability problem of thread rolling die.
3 is the precision of the polished rod part adopts the patent technology of mirror, easy opening and closing, good seal performance, has solved the original polished rod parts grinding machine precision is not high, time-consuming long problem.
4 it is fall off parts adopt numerical control technology a molding, high precision, light sealed performance is good, also the eradication of the original closing part adopts two clamping turn down seal, concentricity, pour sealing easy leakage; Side parts adopt milling machine dial index, and the problems of slow processing process, takes a long time.
5 T slot end parts are forging forming process, high efficiency and low cost. Pneumatic valve rod of a complete set of production process and reached the international advanced level.
